Re: models.ManyToManyField

The first solution works like this:

If you create a foreign key from ModelA to ModelB, Django automatically create something like B.modela_set that works just like the objects attribute, but just for the A objects that are related to B, right?

That's why you can du stuff like attore.film_set.all() to get all the films the actor was in. Django creates film_set for you in Attore instances because you have a ForeignKey from Film to Attore

So, if you wanna list all the films for each actor, something like

actors_dict = dict()

actors = Attore.objects.all()

for actor in actors:

  full_name = '{} {}'.format(actor.nome, actor.cognome)

  actors_list[actor.cognome] = [film.titolo for film in actor.film_set.all()]

Then actors_list would be a dictionary like:

{
  'Nicholas Cage': ['Gone in 60 Seconds', 'Face Off'],

  'Jack Nicholson': ['Batman', 'The Shining']
}

There are different ways of doing this, and I get the feeling you'd like something with templates. But this is pretty much the gist of it.

I think it is the first solution that you have proposed, but I can't figure out how to use it. Also, is there a way to make sure that the ID is automatically taken? With a proper publisher for loop I would like all the lists of movies for each actor.

This is my urls.py

from django.conf.urls.defaults import *

urlpatterns = patterns('',    

    (r'^Film$', 'Database.views.film'),

)

and this is my views.py

from django.shortcuts import render_to_response

from django.template import RequestContext

from models import *

def film(request):

    film = Film.objects.all()

    return render_to_response('Film.html', { 'film': film, })

Thanks for the help.
