I'm just getting familiar with Django and I think I've got all the
basics... and I have lots of experience with Python and MySQL, but I'm

I'm hoping to use Django with a legacy database and I'm suspecting
that things are not working as they should because the database has
tables that lack the "id" column that Django generates from the same
model. Searching the documentation, I don't see anything that
indicates this is required, but

I find myself frequently frustrated by examples and tutorials that include
code snippets that don't identify where they live. In particular, I haven't
quite figured out where forms usually are defined and then where they need
to be imported.
I see that forms sometimes are in a file called forms.p

Thanks... that's what I was guessing. But it appears to me that I sometimes
see ModelForms in models.py... wondering if that's typical.

I am having a problem with locking on MySQL and can't quite figure out
what's causing it. Although I have some scripts that do raw SQL, none of
them are running, I see no other transactions in the process list, yet when
I call save() on one of my objects, the transaction locks, seemingly
forever.
