Since campsite types need a media, i have to insert also images to the
media relation. The best would be to use PostgreSQL’s
pg_read_binary_file to read the media content from actual files when
inserting the new rows, but the files need to be within the database
cluster directory, or have to use an absolute path when running as a
superuser to read from files outside the cluster directory, which means
that it would depend on the path where i leave the files, that is
different in development that in staging.
To avoid that problem i can simply insert the rows using their base64
strings, with PostgreSQL’s decode. The images are kind of small, but
i was worried that each change in demo.sql would duplicate that data in
git, even if the change is not related to the images, because git stores
the whole file; even if small, soon everything adds up.
I do not care if the _final_ demo.sql is big, as this file is packaged
in a different deb and is only installed in staging, so i’ve chosen to
use m4 to build a single “amalgamated” SQL file from the base .sql
file and the individual image files converted to base64 strings. That
way, each image is individually managed by git and the base .sql file
does not balloon up for each little change.
Changed m4’s quotes to [[ ]] because the default ` ' was interfering
with Intellij’s syntax highlighting.
It does nothing more than to server a single page that does nothing
interesting.
This time i do not use a router. Instead, i am trying out a technique
i have seen in an article[0] that i have tried in other, smaller,
projects and seems to work surprisingly well: it just “cuts off” the
URI path by path, passing the request from handler to handler until
it finds its way to a handler that actually serves the request.
That helps to loosen the coupling between the application and lower
handlers, and makes dependencies explicit, because i need to pass the
locale, company, etc. down instead of storing them in contexts. Let’s
see if i do not regret it on a later date.
I also made a lot more packages that in Numerus. In Numerus i actually
only have the single pkg package, and it works, kind of, but i notice
how i name my methods to avoid clashing instead of using packages for
that. That is, instead of pkg.NewApp i now have app.New.
Initially i thought that Locale should be inside app, but then there was
a circular dependency between app and template. That is why i created a
separate package, but now i am wondering if template should be inside
app too, but then i would have app.MustRenderTemplate instead of
template.MustRender.
The CSS is the most bare-bones file i could write because i am focusing
in markup right now; Oriol will fill in the file once the application is
working.
