Had to add an `unsafe` function to be able to translate text with HTML
fragments in it, although the fragments are added back with printf
because the login link is actually not translatable.
It turns out i have been **years** doing this wrong: you are supposed to
pass that value as a text, like 'CURRENT_TIMESTAMP', not like the
keyword so that it returns the current timestamp as a timestamptz.
However, i have been doing it wrong because of a bug in previous
versions of pgTAP[0], that did not take into account keywords such as
CURRENT_TIMESTAMP or CURRENT_DATE and was comparing their actual values,
not the names, therefore i thought that i misread the documentation.
Only now have discovered this because Debian 12 upgraded pgTAP version
to 1.2.0.

I tried to have a log line that uses the “common” format from Apache,
because i thought that it would help me reuse regexps i have defined for
fail2ban filters and such.
However, it makes no much sense.
For once, i was repeating the date and time: log.Printf already does
that for me.
And, second, i do not need that data in Numerus’ log because i always
run it behind a proxy that _has_ a “common”-formatted log file, so
there is no need for me to repeat all that data again.
What i need is the IP, to know whether remotedAdd() function works as
expected; the method, to check that the override does its job; the path,
to know what resource the browser requested; the response status code,
so that i do not need to open the browser console for that; the response
size, to keep on eye that i do not return a lot of data; and the
total response time, to realize how long my unoptimized SQL queries
slows the application down.
The rest, Apache should do its job and record it in its log file for
fail2ban and whatever i need the logs for in the future.
I need the actual remote address to add fail2ban rules for it, but i
also to not want everyone to be able to fake X-Forward-For HTTP headers.
Which can contain multiple ip addresses, by the way, so i have to get
only the first one, as the others will be the proxies that the request
has been (re)forwarded to.
The same as for invoices: to allow people to have their own numbering
scheme, and for these that start using the program in the middle of the
current year.
I have to use a value to be used as “none” for payment method and
contact. In PL/pgSQL add_quote and edit_quote functions, that value is
NULL, while in forms it is the empty string. I can not simply pass the
empty string for either of these fields because PL/pgSQL expects
(nullable) integers, and "" is not a valid integer and is not NULL
either. A conversion is necessary.
Apparently, Go’s nil is not a valid representation for SQL’s NULL with
pgx, and had to use sql.NullString instead.
I also needed to coalesce contact’s VATIN and phone, because null values
can not be scanned to *string. I did not do that before because
`coalesce(vatin, '')` throws an error that '' is not a valid VATIN and
just left as is, wrongly expecting that pgx would do the job of leaving
the string blank for me. It does not.
Lastly, i can not blindly write Quotee’s tax details in the quote’s view
page, or we would see the (), characters for the empty address info.
They are mostly the same as invoices, but the contact and payment method
are optional, thus, like other optionals fields, i created relations to
link these that have payment method or contact, to avoid NULL columns in
quote.
Still missing functions to add and edit quotations, and views to compute
their tax and total amount.
This is because when i create the demo users then i can no remove the
available languages before users, due the constrain, and i can no use
sqitch rebase or revert.
This is for new users that do not start using the application from the
beginning of the current fiscal year and, therefore, need to create
invoices starting from a specific number.
I had to change the constraint on the currval to allow zero, otherwise
it would not be possible to set 1 as the next number, because users
can also not delete the row.
It is better that way because it works without JavaScript; if HTMx is
not available, it will just use regulars forms.
The problem is that most of the submit buttons where using formaction
to send the request to a different action, and only one button was the
“real” action. Since i could not pass the formaction to
invoice-product-form template, i have changed the “default” action to
the one with “ancillary” functions.
I have to use a different action to remove for each product because i
can not pass the index to the backend without JavaScript: it only
depends on the button click, that already has a name for the action.
Thus, in a way, i have “merged” the action and the index in a single
name.
With this button, it is no longer necessary to set the quantity to zero
to remove, at least not with JavaScript. This is why i am using Alpine:
to use x-cloak and hide it from non-JavaScript users.
Although, i wonder if it would not be better to use HTMx for that?
There is no point in creating a new invoice without products, thus we
were forcing users to always use the “Add product” button for no reason
other than it was easier for me….
I wanted to add the product inside ServeInvoice, when the slug is “new”,
but then it tried to compute the invoice total without price or quantity
and it failed. Thus, i add that product after it has done the
computation query.
I tried this already when i started adding filters, but i tried to use
AlpineJS for that, and could not because it would reset the context each
time i submitted the filters, due to HTMx replacing the whole content.
I realized that the only thing i need is some “flag” to show and hide
the form with CSS. I do not even need AlpineJS for that, but i used it
anyway because then i can use the x-cloak thing to hidde the toggle
button for users with JavaScript disabled.
Similarly, the body by default has that “flag” set in the markup, and is
removed when AlpineJS is initialized, thus if JavaScript is disabled the
filters form is shown nevertheless.
That column was supposed to have a checkbox for batch operations, but
we do not have any operation that would like to perform to many products
or contacts at the same time. For now, at least.
I want the `white-space: pre` to preserve the newline characters that
users may have used, but this prevents line wrapping and long lines are
not confined within the page margins.
`pre-line` preserves the newlines, but collapses spaces and tabs, and
wraps long text, which is more what i want.
