Apparently, each campsite type could have different check-in and
check-out times, thus i need them in the database.
I thought about using an integer or a datetime field, but customer seems
to want a text field to maybe add “before” and “after” there as well.
Translatable text it is.
Previously, the only type with options was plots, that was always the
third fieldset, which was the wrong thing to hardcode, but it was done
in a hurry. Now there are more types with options, so we have to do it
properly.
I also changed the translatable link to not include any HTML, because it
meant that i had to retranslate them just to add a new attribute, that
does not make much sense—the attribute is not even translatable, thus
all translations must include it verbatim.
I tried to use ../, and ../../ to make the routes relatives, but it
would not work well because the same page would have two URLs, one
ending with slash and another without, and the relative links would be
different on each case.
I need to have a single top-level element in order to serialize to XML
when returning the editor’s content back to the text area, because,
unlike PostgreSQL, XMLSerializer only works with XML documents.
I added a <div> because this is the least “semantic” block element there
is, but Oriol seems to have trouble in services when trying to align
services using a grid due to this extra div.
Now i still use the div to serialize to XML, but then remove that
top-level element from the output string by stripping out its label. I
can not be sure that all browsers would serialize the <div> in the
same way, thus i can not use fixed indices in call to substring.
This is mostly because it is required for the “Digital Kit”, but it also
works in our favor because now i can version the URL to the static
resources.
Go 1.18 adds the info from git if the package is build from a git
repository, but this is not the case in OBS, so i instead relay on a
constant for the version number. This constant is “updated” by Debian’s
rules, mostly due to the discussion in [0].

It is for people aged 17 or olded, not 16. I was confused by the
expression “over 16”, that **seems** to mean 17 or older, but actually
includes people aged 16, too.
There is no way, for now, to add, edit or remove users, because
currently we only need to list users.
I can not give admins access to the user table, for security
permissions, so i had to create a new view. I could name it also ‘user’
in ‘camper’ scheme, but then i was afraid i would have problems with
unit tests and their search_path, so instead i called it
‘company_user_profile’, which is like ‘user_profile’ but for all users
in ‘company_user’.
I created a new Go package for it, rather than add the admin handler in
‘auth’, because ‘template’ depends on ‘auth’, and rendering from ‘auth’
would cause a dependency loop.
I needed to have the roles in gettext to translate them, but there is
no obvious place where to put the call to PgettextNoop. For now, there
are in ‘NewAdminHandler’ because it is called once in the application’s
lifetime and they actually do not matter much.
Without the position relative, the booking button is no longer on top
of the carousel depending on the screen resolution, and Oriol wants less
gap between the carrousel and the next section.
I misunderstood Oriol, and what he really wanted was to have the arrows
on top of the image, not just move the arrows from below to above. Thus,
I no longer need the carrousel to be a flex because the buttons are now
absolutely position (slick.css already sets the container to relative
position).
These arrows need to be visually inside a single container, to have a
white background, but Slick adds the two arrows separately. I had to
move them close together, remove the radius from the “common edge”, and
use padding to “move” the arrows, rather than translation, in order to
avoid showing a gap.
Oriol did not like that this carousel was different from the rest, and
wanted to have it like the rest, but showing only one slide at a time,
like the customer wants.
He also wanted the arrows for **all** carousels to be in the top-right
corner instead of bottom-right, mostly because the customer complains
that she does not see the arrows if they are on the bottom, and Oriol
does not like the arrows to the sides.
This is a separate carousel from the one displayed at the bottom with
location info; it is, i suppose, a carousel for the hero image.
For the database, it works exactly as the home carousel, but on the
front had to use AlpineJS instead of Slick because it needs to show a
text popping up from the bottom when the slide is show, something i do
not know how to do in Slick.
It now makes no sense to have the carousel inside the “nature” section,
because the heading is no longer in there, and moved it out into a new
“hero” div.
Since i now have two carousels in home, i had to add additional
attributes to carousel.AdminHandler to know which URL to point to when
POSTing, PUTting, or redirecting.
I was using a <form> to delete slides and other such elements before
adding the form to sort these same elements with drag and drop, without
realizing that i was wrapping the existing delete <form>s, that now
would not submit properly—they were submitting the sort form instead.
Customer does not want the new “masonry-like” design of the surroundings
page, and wants the same style they already had: a regular list with
text and photo, alternating the photo’s side.
And, of course, they want to be able to add and edit them themselves. It
is like another carousel, but with an additional rich-text description.
The photos that we had in that page are no longer of use.
Had to create a custom build of CKEditor with the following plugins
added-in:
* Autoformat
* Block quote
* Bold
* General HTML Support
* Heading
* Image
* Image caption
* Image resize
* Image style
* Image toolbar
* Image upload
* Indent
* Italic
* Link
* Link image
* List
* Media embed
* Simple upload adapter
* Source editing
* Table
* Table toolbar
* Text transformation
The important bit is the “Simple uploader adapter”, that i modified to
upload the file as `media` instead of the default `upload` (i.e.,
modified ckeditor.js to replace "upload" with "media").
I also had to add the CSRF header somewhere in the HTML document for
JavaScript to be able to retrieve it and pass it to the uploader
adapter, or i would have to disable CSRF validation in that form, which
i did not like at all.
The pets icon is just the same as the notpet but without the diagonal
bar.
The price is hardcoded in the query for now, as there is no field
in the campsite type.
It is better for mobile users, as they can zoom and pan the map in their
small screens.
Had to increase header’s z-index or the zoom controls would be on top
of it.
By default, it selects the next day, unless the new arrival date is
before the current departure, in which case is left as is, because the
idea is to help people avoid useless calendar selections when booking
for next three or four months: they would need to change the month
twice, and now only at most one.
locale.Translation and form.L10nInput are no longer used.
The translation type in Postgres is now also useless, and i believe it
was never used, but i keep it because I already have a tag and i can not
just remove it, meaning that dropping it is more trouble that worth it.
Customer wants four slides in home’s carousel, while keeping three in
the rest of the carousels.
In mobile screen, Oriol told me to always have a single slide, but in
tablet it is the given number minus one.
Customer does not want a contact page, but a page where they can write
the direction on how to reach the campground, with a Google map embed
instead of using Leaflet, because Google Maps shows the reviews right
in the map.
That means i had to replace the GPS locations with XML fields for the
customer to write. In all four languages.
This time i tried a translation approach inspired by PrestaShop: instead
of opening a new page for each language, i have all languages in the
same page and use AlpineJS to show just a single language. It is far
easier to write the translations, even though you do not have the source
text visible, specially in this section that there is no place for me
to put the language links.
Customer does not want the next slide to show partially; either it shows
theo whole slide, or not at all.
Had to remove the min-width for campsite type’s spiel, or it would make
the whole thing fall over, i do not know why; possibly because slick
could not reduce the width to its expected value.
I use Sortable, exactly like HTMx’s sorting example does[0]. Had to
export the slug or ID of some entries to be able to add it in the hidden
input.
For forms that use ID instead of slug, had to use an input name other
than “id” because otherwise the swap would fail due to bug #1496[1]. It
is apparently fixed in a recent version of HTMx, but i did not want to
update for fear of behaviour changes.
[0]: https://htmx.org/examples/sortable/
[1]: https://github.com/bigskysoftware/htmx/issues/1496
Had to change setup_redsys because admins can not read the current
encrypt key, thus it is not possible to `set encrypt_key =
coalesce(…, encrypt_key)`.
Not that it did much sense, anyway, as i was already inside the branch
of the if when encrpty_key is null.
However, it seems that this also affects in the `on conflict` update. I
assume this is because `excluded` is some kind of row of the relation
and has the same restrictions.
The idea is that the booking form will be prefilled with the values
passed from that other mini-form, and the campsite type is implicit
due to the page where the form is located at, but i need to give it to
the booking page.
The booking page does not yet use that information.
The form is based on the one in the current website, but in a single
page instead of split into many pages; possibly each <fieldset> should
be in a separate page/view. The idea is for Oriol to check the design
and decide how it would be presented to the user, so i needed something
to show him first.
I hardcoded the **test** data for the customer’s Redsys account. Is
this bad? I hope not, but i am not really, really sure.
The data sent to Redsys is just a placeholder because there are booking
details that i do not know, like what i have to do with the “teenagers”
field or the area preferences, thus i can not yet have a booking
relation. Nevertheless, had to generate a random order number up to
12-chars in length or Redsys would refuse the payment, claiming that
the order is duplicated.
The Redsys package is based on the PHP code provided by Redsys
themselves, plus some hints at the implementations from various Go
packages that did not know why they were so complicated.
Had to grant select on table country to guest in order to show the
select with the country options.
I have changed the “Postal code” input in taxDetails for “Postcode”
because this is the spell that it is used in the current web, i did not
see a reason to change it—it is an accepted form—, and i did not want to
have inconsistencies between forms.
Oriol does not want to waste so much vertical space for the calendar,
and wants it to show in a carousel, initially with only 6 months, and
loading the next three each time the user scrolls past the last.
I now use HTMx in the public page too for this auto-loading behavior,
based on their “infinite scroll” example[0].
Had to put the /calendar URI inside campsites because in the
calendar.gohtml i do not know the current type’s UUID, and can not use
a relative URL to “add subdirectories”, because the type does not end
with a slash.
Had to change season.CollectCalendar to expect the first month and a
number of months to show, to be able to load only 6 or 3 months after
the current, for the initial carousel content, or after the last month
of the carousel.
[0]: https://htmx.org/examples/infinite-scroll/
I had to export the Calendar type from Season to use it from
campsite/types, and also renamed them because season.SeasonCalendar is
a bit redundant compared to just season.Calendar.
I still have not added the HTMx code to switch year because i am not
sure whether Oriol will want to show a whole year or just half a year.
The calculation for the text color taking into account the contrast with
the background is from [0].

In the old website, the prices where show with all the options, but in
the new design only a single price is show, that in the case of
campsites with options is the price per night of the “base” plus the
minimum options selected.
This is the text that introduces the carousel; it is not a spiel, but
this is what i call it.
It turns out that this text needs to have paragraphs and headings, much
like home’s slider, rather than the one in services page, thus no need
to change its font size or to align all items in the carousel in the
middle.
I can not reuse the carousel package because these carousels need the
campsite site’s slug as a first parameters: i can not have a relation
per campsite type, as i do in home and services pages, because the
campsite types are added by administration types; even if i had a
single relation for slides of home and services pages, these would go
in a different relation due to the foreign key to campsite type.
What i could reuse, however, is the Slide and SlideEntry types from
that package, although i had to export carousel.Translation to be usable
from the types package. I should change that to use locale.Translation,
but this was the easier option, or i would need to change the queries
and templates for carousel package too.
Besides that, they work exactly like the slides in home and services
pages.
I created a common template to show the company address in the footer
and the contact page, and then i realized Go did not like to output my
phone URL in the anchor without having the tel: schema in the template.
I then removed that variable and now the URL is created with tel: and
the phone number with its spaces removed.
I was not sure whether to use PostGIS to store the GPS location of the
company, as i am sure i will only use that point just to show the map.
However, just in case, it is not a big deal.
There is no way to change that from the administration pages for now,
because of time constraints, and it is very unlikely that they will
change the campgrounds’ location in the near future.
The location is in a separate table because i did not want to have to
change every test file, to be honest, but this also makes the map
“optional” without the need for NULL values.
I added the contact address to every public page because the new design
adds it to the footer, so i will be needing it everywhere, just like the
menu.
This calendar is supposed to be edited by admin users, but do not yet
have the complete JavaScript code to do so, thus for now i have made it
read-only.
I do not like confirmation messages: they question user’s actions, and
in general it is better to offer an undo option afterward. However, undo
is harder to implement, and currently i do not have time to do this.
The delete for the session is different because the only repercussion
would be to log in again; the user is not in danger of losing any data
whatsoever.
This one has an input to select the icon. It makes no sense to choose
an icon only by name, thus a <select> is not appropriate, and had to
use a hidden input with a row of button to choose the icon from. This
works now only because there are very few icons; we’ll need to choose
a different approach when there are many more icons.
Since now the icons have to be defined in CSS for both the public and
admin sections, i had to split it into a separate file that both sites
can use. I considered the option to “include” that CSS with m4, like
i do for images in demo.sql, but it made everything too complicated
(e.g., having to call make for each change in the CSS), and decided to
load that CSS in a separate <link>.
We discussed with Oriol how to show these “extra” menu items, as they
can’t be in the horizontal menu we have intended for employees, because
there is not enough horizontal space.
Oriol suggested to move these into the user menu. In fact, the company
settings was already there, which means that i already wanted to do that
from the very beginning, i believe, but i must have forgotten it along
the way…. Or maybe it was because this is where Numerus has the company
settings menu item, too, and i did not see the relation with the rest;
i do not know.
I decided to use a custom attribute for the campsite label in the SVG
because i was a bit wary of reusing ‘id’ for that, specially given that
most labels are number only and XML can not have IDs starting with a
number.
In fact, at least Inkscape and Affinity solve the problem by having an
additional foreign attribute to keep the “group label” in without that
restriction (‘inkscape:label’ and ‘serif:id’, respectively), thus i
thought of doing the same, but with a namespace that i control and be
independent of the design program.
However, it seems that Affinity does not have a way of editing the XML
attributes like Inkscape does[0], thus there is no way of adding or
editing that value from there; i can not ask Oriol to edit the SVG file
in a text editor each time.
We have agreed to reuse the ‘id’ attribute to contain the campsite’s
label by using a specific prefix, that we checked is editable without
issue in Affinity’s UI.

I am using the US terms for campground and campsite, that’s why the
relation is called ‘campsite’ instead of ‘pitch’, but i used the wrong
terminology in the SVG map because the customer uses the UK term and
call themselves campsite, so i mixed things.
It is now the campground map and each individual area is a campsite,
as i have been using all along.
I did not remember that the file was loaded as a module, so i have
to export it in order to use from the <script> in media. That <script>
needs to be also a module and explicitly import the function; since it
is already loaded, the browser does not load the file again.
This link is supposed to be for employees, to see the map and check
on campsites’ availability. Currently, it shows the same for employees
and admins, but it will need to change.
I intend to use the same SVG file for customers and employees, so i had
to change Oriol’s design to add a class to layers that are supposed to
be only for customers, like trees. These are hidden in the admin area.
I understood that customers and employees have to click on a campsite to
select it, and then they can book or whatever they need to do to them.
Since customers and employees most certainly will need to have different
listeners on campsites, i decided to add the link with JavaScript. To
do so, i need a custom XML attribute with the campsite’s identifier.
Since i have seen that all campsites have a label, i changed the
“identifier” to the unique combination (company_id, label). The
company_id is there because different companies could have the same
label; i left the campsite_id primary key for foreign constraints.
In this case, as a test, i add an <a> element to the campsite with a
link to edit it; we’ll discuss with Oriol what exactly it needs to do.
However, the original design had the labels in a different layer, that
interfered with the link, as the numbers must be above the path and
the link must wrap the path in order to “inherit” its shape. I had no
other recourse than to move the labels in the same layer as the paths’.
Have to call Dialog.showModal when HTMx loaded the dialog in the DOM,
so had to add a onLoad event listened that checks whether the loaded
element is actually a DIALOG.
Had to restrict the margin: 0 for all elements (*) to exclude dialog,
because the browser sets it to auto, and i did not want to set it again
just because i was too overzealous with my “reset”.
The rest of the CSS is just to have a sticky header and footer, and see
the cancel button, that works as a “close”, all the time.
Finally, i realized that if i add the dialog at the end of the fieldset
and let HTMx inherit its hx-target and hx-swap, i no longer need to set
them in the dialog, as HTMx will always replace the fieldset, and i can
have the dialog side by side the current content of the fieldset, that
it was very confusing seeing it disappear when trying to select a new
media.
The cancel button could now just remove the dialog instead of making the
POST, but in local it makes no difference; we’lls see what happens on
production.
It makes easier to upload new images from the place where we need it,
instead of having to go to the media section each time.
It was a little messy, this one.
First of all, I realized that POSTint to /admin/media/picker to get the
new media field was wrong: i was not asking the server to “accept an
entity”, but only requesting a new HTML value, just like a GET to
/admin/media/upload requests the form to upload a new media, thus here
i should do the same, except i needed the query parameters to change the
field, which is fine—it is actually a different resource, thus a
different URL.
Then, i thought that i could not POST the upload to /admin/media,
because i returned a different HTML —the media field—, so i reused the
recently unused POST to /admin/media/picker to upload that file and
return the HTML for the field. It was wrong, because i was not
requesting the server to put the file as a subordinate of
/admin/media/picker, only /admin/media, but i did not come up with any
other solution.
Since i had two different upload functions now, i created uploadForm’s
Handle method to refactorize the duplicated logic to a single place.
Unfortunately, i did not work as i expected because uploadForm’s and
mediaPicker’s MustRender methods are different, and mediaPicker has to
embed uploadForm to render the form in the picker. That made me change
Handle’s output to a boolean and error in order for the HTTP handler
function know when to render the form with the error messages with the
proper MustRender handler.
However, I saw the opportunity of reusing that Handler method for
editMedia, that was doing mostly the same job, but had to call a
different Validate than uploadForm’s, because editMedia does not require
the uploaded file. That’s when i realized that i could use an interface
and that this interface could be reused not only within media but
throughout the application, and added HandleMultipart in form.
Had to create a different interface for multipart forms because they
need different parameters in Parse that non-multipart form, when i add
that interface, hence had to also change Parse to ParseForm to account
for the difference in signature; not a big deal.
After all that, i realized that i **could** POST to /admin/media in both
cases, because i always return “an HTML entity”, it just happens that
for the media section it is empty with a redirect, and for the picker is
the field. That made the whole Handle method a bit redundant, but i
left it nevertheless, as i find it slightly easier to read the
uploadMedia function now.
This is required if requesting an admin page via HTMx; i do not think it
is done as of now, except for the media picker, that has no layout
because i do not want to update the title.
It made no sense to have a file upload in each form that needs a media,
because to reuse an existing media users would need to upload the exact
same file again; this is very unusual and unfriendly.
A better option is to have a “centralized” media section, where people
can upload files there, and then have a picker to select from there.
Ideally, there would be an upload option in the picker, but i did not
add it yet.
I’ve split the content from the media because i want users to have the
option to update a media, for instance when they need to upload a
reduced or cropped version of the same photo, without an edit they would
need to upload the file as a new media and then update all places where
the old version was used. And i did not want to trouble people that
uploads the same photo twice: without the separate relation, doing so
would throw a constraint error.
I do not believe there is any security problem to have all companies
link their media to the same file, as they were already readable by
everyone and could upload the data from a different company to their
own; in other words, it is not worse than it was now.
This page is more or less similar to home, in terms of database: it
has a carousel and a list of items; in this case, the definition of
campsite services.
As i said early, when adding the home carousel, this carousel has its
own relation and set of functions to manage slides. They are also
duplicated in Go code, but i think i will need to refactor it later to
a carousel package or something like that, because both relations have
the exact same fields and types, so it makes no sense to have twice the
same code.
I already did it with the CSS and JavaScript code, mostly because it was
easier to replace the `.surroundings div` selector with `.carousel`, and
because that way i can have a single template that loads and initializes
Slick.
There is no UI to create or edit service definitions, although there are
the SQL functions, because i have no more time now, and Oriol needs to
check that the style is correct for that page.
This page is “highly stylized”, with a masonry-like grid, that i did not
know how to generate automatically from data defined in PostgreSQL,
therefore with Oriol we agreed to have this one as a static page and
we will see what we can do if the customer asks to be able to change
it.
I was a bit undecided on whether the icons in the bottom part of the
page should be defined in the CSS or with style="" and CSS variables,
like i do for the campsite type in the home page.
At first i thought that it should use CSS variables, mostly for
coherence: if another section of the web does it for its background
image, why no this one. The difference is that the home page is
dynamically created from the database, while this page is static and we
know what icons we need, thus it makes more sense to move it to the
stylesheet file, because then it will be downloaded by user agents that
actually want to use it (e.g., browsers, but not Braille terminals).
I debated with myself whether to create the home_carousel relation or
rather if it would be better to have a single carousel relation for all
pages. However, i thought that it would be actually harder to maintain
a single relation because i would need an additional column to tell one
carrousel from another, and what would that column be? An enum? A
foreign key to another relation? home_carousel carries no such issues.
I was starting to duplicate logic all over the packages, such as the
way to encode media paths or “localization” (l10n) input fields.
Therefore, i refactorized them.
In the case of media path, i added a function that accepts rows of
media, because always need the same columns from the row, and it was
yet another repetition if i needed to pass them all the time. Plus,
these kind of functions can be called as `table.function`, that make
them look like columns from the table; if PostgreSQL implemented virtual
generated columns, i would have used that instead.
I am not sure whether that media_path function can be immutable. An
immutable function is “guaranteed to return the same results given the
same arguments forever”, which would be true if the inputs where the
hash and the original_filename columns, instead of the whole rows, but
i left it as static because i did not know whether PostgreSQL interprets
the “same row but with different values” as a different input. That is,
whether PostgreSQL’s concept of row is the actual tuple or the space
that has a rowid, irrespective of contents; in the latter case, the
function can not be immutable. Just to be in the safe side, i left it
stable.
The home page was starting to grow a bit too much inside the app
package, new that it has its own admin handler, and moved it all to a
separate package.
I am not happy with the localization interface for admins, but it is the
easier that i could think of (for me, i guess), with a separate for
each language.
I am not at all proud of the use of RecordArray, but i did not see the
need to create and register a type just to show the translation links.
I might change my mind when i need to add more and more translation
links, but only it the current interface remains, which i am not that
sure at the moment.
There is a big difference between the item that has the submenu for
lodges and languages: languages is a link to the “alternate” version of
the page, while the lodges has no page to link to. Therefore, one is an
anchor while the other is a button, to make a semantic difference, but
both have the exact same appearance here.
This is the image that is shown at the home page, and maybe other pages
in the future. We can not use a static file because this image can be
changed by the customer, not us; just like name and description.
I decided to keep the actual media content in the database, but to copy
this file out to the file system the first time it is accessed. This is
because we are going to replicate the database to a public instance that
must show exactly the same image, but the customer will update the image
from the private instance, behind a firewall. We could also synchronize
the folder where they upload the images, the same way we will replicate,
but i thought that i would make the whole thing a little more brittle:
this way if it can replicate the update of the media, it is impossible
to not have its contents; dumping it to a file is to improve subsequent
requests to the same media.
I use the hex representation of the media’s hash as the URL to the
resource, because PostgreSQL’s base64 is not URL save (i.e., it uses
RFC2045’s charset that includes the forward slash[0]), and i did not
feel necessary write a new function just to slightly reduce the URLs’
length.
Before checking if the file exists, i make sure that the given hash is
an hex string, like i do for UUID, otherwise any other check is going
to fail for sure. I moved out hex.Valid function from UUID to check for
valid hex values, but the actual hash check is inside app/media because
i doubt it will be used outside that module.
