If there were contacts added with add_contact passing an empty string
to `web` parameter, contact_web would not have such row, and during the
revert the `web` parameter of contact would end up being NULL.
The legal stuff. Required by Spanish law when setting up a site intended
for pecuniary gain, directly or indirectly.
Now we have more pages to the “public web”, and moved the header and
footer from home to the common layout. I also took the opportunity to
change the element from <div> to the appropriate element based on their
use (i.e., <header> and <footer>).
I removed the <div> around the logo because i did not see any use for
it. I may be from a previous design iteration, but it had no style
applied nor any usage at all in JavaScript.
I mistakenly thought that <small> was de inverse of the deprecated <big>
element, but apparently it is for small-print text and such, thus suited
for this case.
This is mostly to reassure people that we are running the same version
as published on numerus.cat. Or at least, try.
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].

There are no sales yet in Numerus, and having that summary there
confuses people.
He left the space there, without any text or background color, to
maintain the position of the rest.

This is mainly to be able to stylize them using CSS; the current style
i set i just a placeholder to check that it works as expected.
Most of these links needs to check for the URI’s prefix, because they
are links to a whole section, but the first link must check for the
exact match, otherwise it would match every other URI, as all of them
start with /company/{uuid}.
The server does not return the markup for the top navigation when usin
HTMx, though, hence i have to change the current class using JavaScript.
I am not sure if the correct value for aria-current is “page” when the
link is not for the actual page the user is currently in, like when is
in the new quote page, but it seems to be the most appropriate value
from the enumeration given in the specifications, except, perhaps, for
the “location” value, but i was unable to find any example of that value
anywhere.
Part of #89.
I use customized built-in components, extended from any HTML elements
(e.g., HTMLDivElement), for product search, multiselect, and tags input
fields. The idea is that people that without JavaScript could still use
the regular, non-customized, inputs.
It turns out, this does not work so well: the CSS assumes that
JavaScript is enabled, and web components supported by the browser. If
one of these fails, then the controls are unusable—the multiselect is
too short, and the tags field accepts invalid characters that the
backend does not validate until it fails with a database error.
We discovered this because Apple does not implement customized built-in
components[0], hence it does not use my JavaScript code and forms,
the expenses forms in particular, are almost useless.
The way to fix this is to replace the regular inputs with autonomous
web components, extended from HTMLElement, using JavaScript, because
it would only do so with JavaScript enabled, and the CSS style would
only apply to these components, not the regular input fields.
However, currently i do not have time to do the proper fix, and have
to use a polyfill for Safari to support customized built-in components.
Shame.

This is for users that belong to more than one company. It is just a
page with links to the home of each company that the user belongs to.
Had to add a second company to the demo data to test it properly, even
though i already have unit tests for multicompany, but, you know….
It makes no sense to retrieve the same OIDs each and every connection,
because they are not going to change unless the database is reset,
something it is very unlikely to happen in production.
Thus, it is best to query them the first time the application connects
to the database, that it is done at startup to query the available
languages, and then reuse the OIDs.
I can get away of using an “unprotected” map, instead of sync.Map or a
map in tandem with sync.RWMutex, because the application establishes a
connection at startup from a single goroutine, and it registers _all_
types we will need to register within the application’s lifespan, hence
it there will be no more writes to that map once the web server is
listening for incoming connections.
This is risky, however, and i hope i do not have to regret it.
The problem is that parse_price('', 2) returned NULL instead of throwing
and exception: it seems that accessing var[1] of a text[] variable set
to the empty array, {}, returns NULL, and NULL::integer is, of course,
still NULL.
Apparently, this is the only case, until now, that i had an empty
subtotal, and i did not know what to do: should i keep the function as
is and just handle its NULL return, change it to return 0 in that case,
or raise an exception?
The argument for the first two options, to leave it as is or to
return zero, was that it was convenient for me to allow empty strings as
input values, because that’s what i get from an empty <input>; returning
zero would avoid an extra coalesce everywhere the function was used.
The argument in favor to the last option, an exception, was that the
empty string does not represent an integer, nor a “unknown” (NULL)
integer, therefore the function should do the same when i pass in any
other string that does not represent an integer, just as “a.b”.
At the end i went for option three, because it is the one that breaks
fewer expectatives: casting an empty string to integer, or passing
an empty string as the first value to to_number() throw and exception in
PostgreSQL; my function should do the same. Heck, that what **i**
expected it to do because of the casting inside the function.
To still allow empty strings as parameter to compute_new_expense_amount,
the only case so far, i only had to check for that empty string and
convert it to the string representation of zero, so that parse_price
returns the value i want for that function. This, of course, breaks
the same expectatives as returning NULL for to_price, but i think it is
OK in this case because to_price is more general—used in many more
cases—than compute_new_expense_amount, which is only intended for that
HTML form.
Closes#77.
When adding “free-form products” to quotes they do not have a product
ID, but i has coalescing the NULL to zero because product_id is an
integer and can not coalesce a nullable integer to an empty string.
However, that causes problems when trying to create the invoice for that
quote, because it tries to add products that have an ID of 0 and the
foreign key, obviously, fail.
At first i modified NewInvoiceProductArray.EncodeBinary to check for
"0" as well as the empty string, but i realized this was wrong: the
problem was because i gave these products an ID when they do not have
any. And the solution is to cast product_id to a text, which is what
will get converted anyway because i the only thing i do to it is to
store to a string-backed InputForm field.
Closes#73.
This was requested by a potential user, as they want to be able to do
whatever they want to do to these lists with a spreadsheet.
In fact, they requested to be able to export to CSV, but, as always,
using CSV is a minefield because of Microsoft: since their Excel product
is fucking unable to write and read CSV from different locales, even if
using the same exact Excel product, i can not also create a CSV file
that is guaranteed to work on all locales. If i used the non-standard
sep=; thing to tell Excel that it is a fucking stupid application, then
proper applications would show that line as a row, which is the correct
albeit undesirable behaviour.
The solution is to use a spreadsheet file format that does not have this
issue. As far as I know, by default Excel is able to read XLSX and ODS
files, but i refuse to use the artificially complex, not the actually
used in Excel, and lobbied standard that Microsoft somehow convinced ISO
to publish, as i am using a different format because of the mess they
made, and i do not want to bend over in front of them, so ODS it is.
ODS is neither an elegant or good format by any means, but at least i
can write them using simple strings, because there is no ODS library
in Debian and i am not going to write yet another DEB package for an
overengineered package to write a simple table—all i want is to say
“here are these n columns, and these m columns; have a good day!”.
Part of #51.
Since most of PL/pgSQL functions accept a `uuid` domain, we get an error
if the value is not valid, forcing us to return an HTTP 500, as we
can not detect that the error was due to that.
Instead, i now validate that the slug is indeed a valid UUID before
attempting to send it to the database, returning the correct HTTP error
code and avoiding useless calls to the database.
I based the validation function of Parse() from Google’s uuid package[0]
because this function is an order or magnitude faster in benchmarks:
goos: linux
goarch: amd64
pkg: dev.tandem.ws/tandem/numerus/pkg
cpu: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz
BenchmarkValidUuid-4 36946050 29.37 ns/op
BenchmarkValidUuid_Re-4 3633169 306.70 ns/op
The regular expression used for the benchmark was:
var re = regexp.MustCompile("^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-4[a-fA-F0-9]{3}-[8|9|aA|bB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}$")
And the input parameter for both functions was the following valid UUID,
because most of the time the passed UUID will be valid:
"f47ac10b-58cc-0372-8567-0e02b2c3d479"
I did not use the uuid package, even though it is in Debian’s
repository, because i only need to check whether the value is valid,
not convert it to a byte array. As far as i know, that package can not
do that.

I want this button, as well as the submit button, to be on a row below
the filters’ input, especially for quotes and invoices, that have the
most filters and looks weird with the button wedged in. Thus, i added
a <fieldset> around all the filters.
Closes#69
Sometimes, if the space is tight, the browser may break the radio button
and the single-word label for the toggle, which looks very weird.
I did not set nowrap to all radio button because the no wrap would
prevent long labels to break, and i am not sure if there is any such
radio option. I know that for the toggle there is not any.
This works mostly like invoices: i have to “update” the expense form
to compute its total based on the subtotal and the selected taxes,
although in this case i do no need to compute the subtotal because that
is given by the user.
Nevertheless, i added a new function to compute that total because it
was already hairy enough for the dashboard, that also needs to compute
the tota, not just the base, and i wanted to test that function.
There is no need for a custom input type for that function as it only
needs a couple of simple domains. I have created the output type,
though, because otherwise i would need to have records or “reuse” any
other “amount” output type, which would be confusing.\
Part of #68.
Works exactly the same as for expenses, and this is sometimes convenient
for keeping transfer slips from customers and such.
I actually did not know where to add the download from this attachment,
because if add a column to the index it can easily be confused with the
download icon for the actual invoice.
Part of #66.
We only want two statuses for expense: not yet paid (pending), and paid.
Thus, it is a bit different from quotes and invoices, because expenses
do not pass throw the “workflow” of created→sent→{pending,paid}. That’s
way in this case the status field is already in the new expense form,
instead of hidden, and by pending is not equivalent to created but
unpaid (i.e., the same status color).
With the new select field in the form, the file field no longer can
span two columns or it would be alone on the next row.
Closes#67.
This is mostly to have better contrast with the alternative row color
(#EDE95E), because with Firefox’s default link color (#1B6ACB), on Linux
at least, the contrast ratio is 4,5:1.
Closes#62.
This was requested by Oriol; there are no other technical or legal
requirements for this.
I can not simply append the customer name to the file because it could
have characters that are not valid in file name depending on the
operating system, so i have to “slugify” it.
Closes#65
There was no explicit `order by` in the queries that list the products
of quotes and invoices, so PostgreSQL was free to use any order it
wanted. In this case, since was am grouping first by name, the result
was sorted by product name.
This is not an issue in most cases, albeit a bit rude to the user,
except for when the products *have* to in the same order the user
entered them, because they are monthly fees or something like that, that
must be ordered by month _number_, not by their _name_; the user will
usually input them in the correct order they want them on the invoice or
quote.
Sorting by *_product_id does *not* guarantee that they will always be
in insertion order, because the sequence can “wrap”, but i think i am
going to have bigger problems at that point.
Closes#63
Using Orca or similar accessibility tools, it was not possible to
understand what these “menus” were intended for because they had only
icons without any alternative text, thus nothing to speak aloud with.
By default, when using hx-boost, HTMx adds the `show:top` modifier to
`hx-swap`. This is actually the wanted behaviour in these cases,
because it means that you are following a link to a “different” page,
and it makes sense to start from the top.
However, for quote and invoice forms is a hindrance because you are
usually editing the bottom-most product, as new lines are appended,
therefore you are all the time having to scroll down to the line.
Every. Single. Time.
Here i reverted the show:top to just show:false to keep the scroll as
is. I also added the show:bottom to the new product button, because
that way the window show entirely the new line.
I could not use `show🪟bottom`, however, despite appearing in the
documentation, because that, somehow, ended up doing the same as
`show🪟top`. Not sure if a bug or something i did not understand.
Closes#58.
