Re: How can I access attributes in intermediate class

I was intrigued so I did it, I get this solution:

from models import User, Group, Membership

def example(request):

    example_group_id = 1 #I create only one group to test, this is his id

    group = Group.objects.get(pk=example_group_id)

    for user in group.members.iterator(): #Get all user in the group throught the membership

        membership = Membership.objects.get(person=user, group=group) #Get the membership object using the user and the group as keys

        membership.date_joined # Now you can read your date_joined

Perhaps it isn't the best way to do it, but it works :p

I hope this helps you,

   group = models.ForeignKey(Group)
   date_joined = models.DateField()


What if I want to access Membership.data_joined in Group class?

Thanks
