Posting in several tastypie resources simultaneously - django

Question

Here's what I'm trying to do :
The user creates an Event in my application. Here's the model :
class Event(models.Model):
name = models.CharField(max_length=40)
organizer = models.ForeignKey(UserProfile)
description = models.TextField(null=True)
place = models.TextField(null=True)
confirmed = models.BigIntegerField(null=True)
organizer_part = models.BooleanField(default=True)
slug = models.SlugField()
Right after that, it posts the different people invited to this event, and the different dates that the user chose. Here are the models :
class EventDate(models.Model):
"""Correspondances date-event"""
event = models.ForeignKey(Event)
date = models.BigIntegerField()
class EventPeople(models.Model):
"""Correspondances personne-event"""
event = models.ForeignKey(Event)
phone_number = models.PositiveIntegerField()
name = models.CharField(max_length=32)
answer = models.BooleanField()
participation = models.NullBooleanField()
I'd like to fill those three models in only one request. So far I have to make three requests. I can't see how I could possibly do it.
Any idea would be highly appreciated.

Answer 1

Resource that should work with your models is:
class EventResource(ModelResource):
event_dates = fields.ToManyField(EventDateResource, 'event_dates')
event_peoples = field.ToManyField(EventPeopleResource, 'event_peoples')
class Meta:
queryset = Event.objects.all()
Also you have to create simple EventDateResource and EventPeopleResource.
One one more change in yout models, you need to add related_names:
class EventDate(models.Model):
"""Correspondances date-event"""
event = models.ForeignKey(Event, related_name='event_dates')
date = models.BigIntegerField()
class EventPeople(models.Model):
"""Correspondances personne-event"""
event = models.ForeignKey(Event, related_name='event_peoples')
phone_number = models.PositiveIntegerField()
name = models.CharField(max_length=32)
answer = models.BooleanField()
participation = models.NullBooleanField()
