I totally agree with Glenn.
Every day I suffer of the lack of example in the Python doc.
It would be great that Django does it better.

This will test if one tag has an empty article_set. AFAICT, the question
is on how to find all tags which have an empty article_set. Yes, you

Suppose I have the following two model objects:

Each Article can be associated with multiple Tags and vice versa.

Then perhaps the docs etc. should instead show "raise "

Hi Glenn.
the thing is, if there's anything in django's knowledge to avoid the

this is not possible on trunk , if you are using magic-removal, you can

else:

Can I use _pre_delete() in a model to stop the deletion from
occurring?
I've checked the documentation, but couldn't find anything relevant.

Hi,
when your uncollapse the first time then the right list show only one

If you save without performing any other operation before, then only
the shown entry will saved in the database (others entries will be LOST

Other than the fact that you're using "Users" instead of "User" on the
second line, that should work.
Ah, it was user-error. I was bulk-inserting some data with predefined foreign key ids, but I forgot to create the table that those foreign keys reference, and I didn't set "null=True" in the model. So, the select_related was joining a table that had no records -- thus returning an empty list when
