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.

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 just found out that this is a feature introduced in PostgreSQL 10,
back in 2017.
Besides this being the standard way to define an “auto incremental
column” introduced in SQL:2003[0], called “identity columns”, in
PostgreSQL the new syntax has the following pros, according to [1]:
* No need to explicitly grant usage on the generated sequence.
* Can restart the sequence with only the name of the table and column;
no need to know the sequence’s name.
* An identity column has no default, and the sequence is better
“linked” to the table, therefore you can not drop the default value
but leave the sequence around, and, conversely, can not drop the
sequence if the column is still defined.
Due to this, PostgreSQL’s authors recommendation is to use identity
columns instead of serial, unless there is the need for compatibility
with PostgreSQL older than 10[2], which is not our case.
According to PostgreSQL’s documentation[3], the identity column can be
‘GENERATED BY DEFAULT’ or ‘GENERATED ALWAYS’. In the latter case, it is
not possible to give a user-specified value when inserting unless
specifying ‘OVERRIDING SYSTEM VALUE’. I think this would make harder to
write pgTAP tests, and the old behaviour of serial, which is equivalent
to ‘GENERATED BY DEFAULT’, did not bring me any trouble so far.

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.

I was starting to add the public page for campsite types, creating more
granular row-level security policies for select, insert, update, and
delete, because now the guest users needed to SELECT them and they have
no related company to filter the rows with. Suddenly, i realized that
the role was wrong in the user relation: a user can be an admin to one
company, and employee to another, and guess to yet another company;
the role should be in the company_user relation instead.
That means that to know the role to set to, the user alone is not enough
and have to know the company as well. Had to change all the
cookie-related function to accept also the company’s host name, as this
is the information that the Go application has.
We are no longer going to “stitch up” a whole page based on ACF-like
field, but write the whole page with that information in description.
That change is due to wanting to serve the public-facing part of the web
with the same application.
