django 1.3 - Saving multiple forms does a partial save

I'm having some troubles making multiple forms in django. I have two models, Space and Entity. Each space can have N entities related to it.

I've created a form with two ModelForms, and writed a view that works "apparently". This is, it saves the space form, but not the data on the entity form. I does not make sense to me that saving the forms does a "partial" storage of it.

views.py

def all(items):
    import operator
    return reduce(operator.and_, [bool(item) for item in items])

def create_space(request):

    """
    Create new space with its related entities. In this view the author
    field is automatically filled.
    """
    space_form = SpaceForm(request.POST or None, request.FILES or None)
    entity_forms = [EntityForm(request.POST or None, prefix=str(x)) for x in range(0,3)]

    if request.POST:
        space_form_uncommited = space_form.save(commit=False)
        space_form_uncommited.author = request.user

        if space_form.is_valid() and all([ef.is_valid() for ef in
               开发者_JAVA百科                           entity_forms]):
            new_space = space_form_uncommited.save()

            for ef in entity_forms:
                ef_uncommited = ef.save(commit=False)
                ef_uncommited.space = new_space
                ef_uncommited.save()
            # We add the created spaces to the user allowed spaces
            space = get_object_or_404(Space, name=space_form_uncommited.name)
            request.user.profile.spaces.add(space)
            return redirect('/spaces/' + space.url)

    return render_to_response('spaces/space_add.html',
                              {'form': space_form,
                               'entityform_0': entity_forms[0],
                               'entityform_1': entity_forms[1],
                               'entityform_2': entity_forms[2]},
                              context_instance=RequestContext(request))

forms.py

class SpaceForm(ModelForm):

    """
    """
    class Meta:
        model = Space

class EntityForm(ModelForm):

    """
    """
    class Meta:
        model = Entity

The template code is pasted here because is too long.

You don't need to create objects, ModelForm will do it for you, so remove lines space = Space() and entity = Entity() and don't pass any instance to forms.

And don't reinvent all function, it's already Python built-in. :-)

SOLVED

There was some kind of problem using RAW forms. I converted EntityForm to a ModelFormSet and after that, the Entities got saved.

Fixed also the entity.space delaration, it was storing a NoneObject.

Final code:

views.py

def create_space(request):

    space_form = SpaceForm(request.POST or None, request.FILES or None)
    entity_forms = EntityFormSet(request.POST or None, request.FILES or None,
                                 queryset=Entity.objects.none())

    if request.POST:
        space_form_uncommited = space_form.save(commit=False)
        space_form_uncommited.author = request.user

        if space_form.is_valid() and entity_forms.is_valid():
            new_space = space_form_uncommited.save()
            space = get_object_or_404(Space, name=space_form_uncommited.name)

            ef_uncommited = entity_forms.save(commit=False)
            for ef in ef_uncommited:
                ef.space = space
                ef.save()
            # We add the created spaces to the user allowed spaces

            request.user.profile.spaces.add(space)
            return redirect('/spaces/' + space.url)

    return render_to_response('spaces/space_add.html',
                              {'form': space_form,
                               'entityformset': entity_forms},
                              context_instance=RequestContext(request))

forms.py

from django.forms.models import modelformset_factory
EntityFormSet = modelformset_factory(Entity, extra=3)
