My models.py:
USER_TYPES = (
('D', 'Demo' ),
('F', 'Free' ),
('P', 'Premium'),
)
class BaseProfile(models.Model):
user = models.OneToOneField(User, primary_key=True)
user_type = models.CharField(max_length=1, blank=True, choices=USER_TYPES)
class DemoProfile(models.Model):
user = models.OneToOneField(User, primary_key=True)
demo = models.CharField(max_length=10, blank=True)
...
class FreeProfile(models.Model):
user = models.OneToOneField(User, primary_key=True)
free = models.CharField(max_length=10, blank=True)
...
class PremiumProfile(models.Model):
user = models.OneToOneField(User, primary_key=True)
premium = models.CharField(max_length=10, blank=True)
...
class ProxyProfile(BaseProfile):
class Meta:
proxy = True
def get_profile(self):
if self.user_type == 'D':
return DemoProfile._default_manager.get(user__id__exact=self.user_id)
elif self.user_type == 'F':
return FreeProfile._default_manager.get(user__id__exact=self.user_id)
else:
return PremiumProfile._default_manager.get(user__id__exact=self.user_id)
I use BaseProfile to map user_id to specific user_type. I wanted to use ProxyProfile as proxy which loads user_type depending profiles to ModelForm as shown below
My forms.py:
class ProfileForm(ModelForm):
...
class Meta:
model = ProxyProfile
exclude = ('user','user_type')
...
ProfileForm is provided to django-profiles using following code in urls.py:
urlpatterns += patterns('',
url(r'^profiles/edit/', edit_profile,
{'form_class': ProfileForm},
name='profiles_edit_profile'),
(r'^profiles/',include('profiles.urls')),
)
I've also set in settings.py: AUTH_PROFILE_MODULE = 'main.ProxyProfile'
During user registration all db data is filled correctly (it looks like everything is OK).
I register using form passed to django-registration:
urlpatterns += patterns('',
url(r'^register/$', register,
{'form_class': UserRegistrationForm},
name='registration.views.register'),
(r'', include('registration.urls')),
)
from forms.py:
class UserRegistrationForm(RegistrationFormUniqueEmail, RegistrationFormTermsOfService):
utype = forms.ChoiceField(choices=USER_CHOICES)
def save(self, profile_callback=None):
new_user = RegistrationProfile.objects.create_inactive_user(username=self.cleaned_data['username'],
password.self.cleaned_data['password1'],
email=self.cleaned_data['email'],
)
new_base_profile = BaseProfile(user=new_user, user_type=self.cleaned_data['utype'])
if self.cleaned_data['utype'] == "D":
new_profile = DemoProfile(user=new_user)
if self.cleaned_data['utype'] == "F":
new_profile = FreeProfile(user=new_user)
if self.cleaned_data['utype'] == "P":
new_profile = PremiumProfile(user=new_user)
new_profile.save()
new_base_profile.save()
return new_user
And registration phase works OK.
I've problem with profile edit/details pages. My profiles filtered in ProxyProfile model and used as FormModel in ProfileForm are not rendered (I can't see profile specific fields are not rendered to HTML page) Maybe there is some other way (more like Django way :)) to do this (select and render profile model depending on user_type field which is related to User model).
Thanks in advance :)
