Form with 2 models

[Paddy Joy]

I have an Account model:

class Account(models.Model):

accountname = models.CharField(max_length=50, unique=True)
owner = models.ForeignKey(User)
admins = models.ManyToManyField(User, related_name='admins',
blank=True)
accounts = models.ManyToManyField(User,
related_name='accounts', blank=True)
def __str__(self):
return self.name

I want to create a single form that creates an account and an
owner(contrib.auth.User) at the same time.

Is there an easy way of doing this or do I need to create a custom
form that contains the fields of both models and then separate the
data in my view?

Hi Paddy,

Django forms support normal OOP extension. So you can simply subclass
the built-in user creation form (see
django.contrib.auth.forms.UserCreationForm) and add your relevant
account model fields to it. You could then extend the save() method of
the UserCreationForm to first call the base save method followed by
your own save for the Account model.

What's wrong with creating two different Forms (one for the account,
one for the user) and displaying them together in the template? Django
has no problem with that (it's in fact one of Django's strengths,
being able to mix and match several Forms in a single view&template).

Are you sure that both forms' save() methods will be called on a submit?

Thanks I didn't know I could do that. For some reason I was fixated on
the concept of one form/one view/one template.

I tried as you suggested and it turned out to be pretty straight
forward.

view.py:
@login_required
def CreateAccount(request):

if request.method == "POST":
AccountForm = NewAccountForm(request.POST)
UserForm = CreateUserForm(request.POST)

if UserForm.is_valid() & AccountForm.is_valid():
newuser = UserForm.save()

newaccount = AccountForm.save(commit=False)
newaccount.owner = newuser
newaccount.save()

return HttpResponseRedirect("/account/")

else:
AccountForm = NewAccountForm()
UserForm = CreateUserForm()


return render_to_response('test.html', {"form1": AccountForm,
"form2": UserForm, }, context_instance=RequestContext(request))

test.html:
{% extends "base.html" %}

{% block content %}

<form method="POST" action="">
<table>
{{ form1.as_table }}
{{ form2.as_table }}
</table>
<input type="submit" value="Submit" />
</form>

{% endblock %}
