jordi fita mas 97cf117da3 Manage all media uploads in a single place
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.

jordi fita mas afe77f2296 Add the services page
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.

jordi fita mas f746c82b46 Make home page’s carousel manageable via the database
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.

jordi fita mas f48936f800 Add internationalization and localization of campsite types
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.

jordi fita mas da127124a1 Add cover media to campsite types
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.

jordi fita mas b4919db6c4 Add seasons’ relation, functions, and admin section
Seasons have a color to show on the calendar. I need them in HTML format
(e.g., #123abc) in order to set as value to `<input type="color">`, but
i did not want to save them as text in the database, as integers are
better representations of colors—in fact, that’s what the HTML syntax
also is: an integer.

I think the best would be to create an extension that adds an HTML color
type, with functions to convert from many representations (e.g., CSS’
rgb or even color names) to integer and back.  However, that’s a lot of
work and i can satisfy Camper’s needs with just a couple of functions
and a domain.

To show the color on the index, at first tried to use a read-only
`<input type="color">`, but seems that this type of input can not be
read-only and must be disabled instead.  However, i do not know whether
it makes sense to have a disabled input outside a form “just” to show
a color; i suspect it does not.  Thus, at the end i use SVG with a
single circle, which is better that a 50%-rounded div with a background
color, even if the result is the same—SVG **is** intended for showing
pictures, which is this case.

jordi fita mas 000a2e506e Add tabs to “company settings” pages to link each other
I realized that tax details, campsite types, and campsites pages are all
part of the settings of the company, in the sense that all of them are
set up by a company administrator, and should be under the same item in
the user menu.

The template for these tabs is in the same layout.gohtml file because
i did not want to repeat the tabs everywhere it were used, or i would
forget some of them when adding new tabs, and did not want to add a new
file just for that.

jordi fita mas 50fbfce9ee Add the form to update company’s tax details
It is inside the “user menu” only because this is where Numerus has the
same option, although it makes less sense in this case, because Numerus
is geared toward individual freelancers while Camper is for companies.
But, since it is easy to change afterward, this will do for now.

However, it should be only shown to admin users, because regular
employees have no UPDATE privilege on the company relation.  Thus, the
need for a new template function to check if the user is admin.

jordi fita mas 93364b896c Remove the menu aria role from admin’s layout
Elements with the menu role require complex functionality and a keyboard
navigation[0] that i do not implement, thus the role is incorrect and
more harmful than anything else.

jordi fita mas 216ae20638 Add the campsite relation, HTTP handlers, and form
For now, there is only the label, type, and active fields.  We will need
some field to hold the area on the map, but this requires #4, and
possibly #6, to be finished.

jordi fita mas 208952b964 Add the Active field to the campsite type’s edit form and function
In the new form this field is hidden and always active, because it makes
no sense to add an inactive campsite type.

jordi fita mas 1e1797c1b4 Go back to WYSIWYG for campsite types’ description and remove pages
GrapesJS was not working: too complex for users and not enough for
designers.

Therefore, we decided to use a simple WYSIWYG widget for the campsite
types’ description, while we will do the actual HTML template with an
external editor.  Once that is done, we will convert that HTML to Go
templates and get the description’s content from the database.

Now the pages section has no sense: all the pages will be straight Go
templates.  Only the pages for “special things”, like campsite types,
will use the database, and only for some fields, not the whole page.

jordi fita mas c010b1adba Replace Gutenberg with GrapesJS for pages
I simply can not use Gutenberg without having it choking in its own
over-engineered architecture: using it inside a form, submits it when
clicking the button to change a paragraph’s text size; and using the
custom text size in pixels causes the paragraph component to fail.

The issue with paragraph’s custom text size is that block-editor’s
typography hook expects the font size to be a string, such as '12px' or
'1em', to call startsWith on it, but the paragraph sets an integer,
always assuming that the units are pixels.  Integers do not have a
startsWith method.

Looking at the Gutenberg distributed with the current version of
WordPress, 6.3, seems that now paragraph has a selector for the units,
therefore never sets just the integer.  That made me think that the
components used by the Isolated Block Editor are “mismatched”: maybe in
a previous version of block-editor it was always passed as an integer
too?

I downloaded the source code of the Isolated Block Editor and tried to
update @wordpress/block-library from version 8.14.0 to the current
version, 8.16.0, but fails with an error saying that 'core/paragraph' is
not registered, when, as far as i could check, it was.  Seems that
something changed in @wordpress/blocks between version 12.14.0 and
12.16.0, so i tried to upgrade that module as well; it did not work
because @wordpress/data was not updated —do not remember the actual
error message—.  Upgrading to @wordpress/data from 9.7.0 to 9.9.0 made
the registration of the 'isolated/editor' subregistry to be apparently
ignored, because the posterior select('isolated/editor') within a
withSelect hook returns undefined.

At this point, i gave up: it is obvious that the people that shit
JavaScript for Gutenberg do not care for semantic versioning, and there
are a lot of moving parts to fix just to be able to use a simple
paragraph block!

It seems, however, that there are not many open-source, block-based
_layout_ editors out there: mainly GrapesJS and Craft.JS.  Craft.JS,
however, has no way to output HTML[0], requiring hacks such as using
React to generate the HTML and then pasted that shit onto the page;
totally useless for me.

I am not a fan of GrapesJS either: it seems that the “text block” is
a content-editable div, and semantic HTML can go fuck itself,
apparently.  Typical webshit mentality. By strapping another huge
dependency like CKEditor, but only up to the already out-of-support
version 4, i can write headers, paragraphs and list.  That’s
something, i guess.

jordi fita mas c0f532df4e Add the pages section
For now, this is almost identical to the campsite types, but this
section is for purely informational pages that have no other relation
to the database than “belongs to the same company”.

jordi fita mas d117ce5027 Add public page for campsite type, and function to edit them
Had to export and move PublicPage struct to template because i can not
import app from campsites/types: app already imports campsite for the
http handler, and it, in turn, imports the types package for its own
http handler; an import loop.

Also had to replace PublicPage.MustRender with a Setup function because
the page passed down to html/template was the PublicPage struct, not
whatever struct embeds it.  I was thinking more of Java inheritance here
rather than struct embedding.

jordi fita mas e128680e9a Split templates and handlers into admin and public
I need to check that the user is an employee (or admin) in
administration handlers, but i do not want to do it for each handler,
because i am bound to forget it.  Thus, i added the /admin sub-path for
these resources.

The public-facing web is the rest of the resources outside /admin, but
for now there is only home, to test whether it works as expected or not.

The public-facing web can not relay on the user’s language settings, as
the guest user has no way to set that.  I would be happy to just use the
Accept-Language header for that, but apparently Google does not use that
header[0], and they give four alternatives: a country-specific domain,
a subdomain with a generic top-level domain (gTLD), subdirectories with
a gTLD, or URL parameters (e.g., site.com?loc=de).

Of the four, Google does not recommend URL parameters, and the customer
is already using subdirectories with the current site, therefor that’s
what i have chosen.

Google also tells me that it is a very good idea to have links between
localized version of the same resources, either with <link> elements,
Link HTTP response headers, or a sitemap file[1]; they are all
equivalent in the eyes of Google.

I have choosen the Link response headers way, because for that i can
simply “augment” ResponseHeader to automatically add these headers when
the response status is 2xx, otherwise i would need to pass down the
original URL path until it reaches the template.

Even though Camper is supposed to be a “generic”, multi-company
application, i think i will stick to the easiest route and write the
templates for just the “first” customer.
