Hi. I wrote an intemediary model like this one:
http://docs.djangoproject.com/en/dev/topics/db/models/#extra-fields-on-many-to-many-relationships
########################## models.py #############################
from django.db import models
class Person(models.Model):
name = models.CharField(max_length=128)
class Group(models.Model):
name = models.CharField(max_length=128)
members = models.ManyToManyField(Person, through='Membership')
class Membership(models.Model):
person = models.ForeignKey(Person)
group = models.ForeignKey(Group)
invite_reason = models.CharField(max_length=64)
########################## admin.py #############################
from django.contrib import admin
from intermediary_test.models import Person, Group, Membership
class MembershipInline(admin.TabularInline):
model = Membership
extra = 1
class GroupAdmin(admin.ModelAdmin):
inlines = (MembershipInline,)
admin.site.register(Person)
admin.site.register(Group, GroupAdmin)
##################################################################
The problem is that by the admin interface I can't add more than
two persons in a group (adding them by ``save and continue editing'').
Here's what happens when I try to add another person:

I don't have any problem adding more than two persons
in a group by shell instead.
Any suggestion? Thanks in advance,
