Well it works exactly as you described. You hookup with your JS
framework to change event of selectbox A to run query and update
contents (by calling django view with correct params) of selectbox B.

I suggest that you keep validation to happen on form submit rather than
when updating two field values.

Just find out what is the best way to do that with your JS framework.

Try googling "dependent selectboxes <name of your js framework" and it
should get you going. By adding keyword Django might give even more help.
