Django - Multiple User Profiles

I have done it this way.

PROFILE_TYPES = (
    (u'INDV', 'Individual'),
    (u'CORP', 'Corporate'),
)

# used just to define the relation between User and Profile
class UserProfile(models.Model):
    user = models.ForeignKey(User)
    profile = models.ForeignKey('Profile')
    type = models.CharField(choices=PROFILE_TYPES, max_length=16)

# common fields reside here
class Profile(models.Model):
    verified = models.BooleanField(default=False)

I ended up using an intermediate table to reflect the relation between two abstract models, User which is already defined in Django, and my Profile model. In case of having attributes that are not common, I will create a new model and relate it to Profile.

You can do this in following way. Have a profile which will contains common fields which are necessary in both profiles. And you have already done this by creating class UserProfile.

class UserProfile(models.Model):
    user = models.ForeignKey(User)
    # Some common fields here, which are shared among both corporate and individual profiles

class CorporateUser(models.Model):
    profile = models.ForeignKey(UserProfile)
    # Corporate fields here

    class Meta:
        db_table = 'corporate_user'

class IndividualUser(models.Model):
    profile = models.ForeignKey(UserProfile)
    # Individual user fields here

   class Meta:
        db_table = 'individual_user'

There is no rocket science involved here. Just have a keyword which will distinguish between corporate profile or individual profile. E.g. Consider that the user is signing up. Then have a field on form which will differentiate whether the user is signing up for corporate or not. And Use that keyword(request parameter) to save the user in respective model.

Then later on when ever you want to check that the profile of user is corporate or individual you can check it by writing a small function.

def is_corporate_profile(profile):
    try:
        profile.corporate_user
        return True
    except CorporateUser.DoesNotExist:
        return False

# If there is no corporate profile is associated with main profile then it will raise `DoesNotExist` exception and it means its individual profile
# You can use this function as a template function also to use in template
{% if profile|is_corporate_profile %}

Hope this will lead you some where. Thanks!
