This means we need to pass the user id into the various methods that
call it. But, since it is a pointer, we can use nil if we don't have a
user to check with (this is noted in the service).
This is part of the step towards finishing the creation wizard, all that
is left is the image. However, that is a bigger problem since it
requires a file store and file server. But for now, tags are implemented
and working!
Furthermore, not sure how we are going to handle the searching. Maybe a
full-text search index? For now, it has been ignored, but the filters
seem to be working properly.
Most everything is implemented, included a state handler and a pretty
simple (but workable) system for managing state in HTML. Nice and simple
for now.
There is still much work to be done, but the rest is simple backend
creation and error handling. And then input validation...a nightmare.
