They are not functions because i need to join them with the main
invoice relation, and although possible is a bit more awkward with
functions.
The taxes have their own relation because i will need them grouped by
their name in the PDF, so it will probably be a select for that
relation.
When updating the product list, i forgot to change the index in the
product field’s names and, therefore, i created invoices with only the
products until the first gap.
I have moved everything into a different file, even though it is related
to “db”, because it was starting to get a bit ugly.
Apparently i was doing too much work and had to read the code to
understand what i was supposed to do, because pgtypes’ documentation,
as all other projects from the same author, is almost non-existent.
I needed to add binary encoding function for the new_invoice_product
type, and currently it is not correct: i hardcoded the OID values, but
they are going to be different on a different database.
They are to complete the invoice, so it can be in an invalid date, but
we do not want to force people to finish all required inputs before they
can add products or update quantities, do we?
Now had to add the empty option label for customer in all cases, because
it could be empty, although that should be done regardless in case
someone has a browser that does not validate fields.
I have seen that pgx has the CollectRows function to do the same job as
that function. I can not use CollectRows because it uses generics and
requires Go 1.18, but i have adopted the same nomenclature they use.
Apparently, url.Values.Has and math.MaxInt was added to Go 1.17,
but on Debian Bullseye there is only Go 1.16. I do not want to
install a new version of Go to the server unless there is an
overwhelming reason, and a couple of methods are not. Thus, now i use
Go 1.16 too on my development machine, to avoid situations like this.
