Django allauth saving user user fields with registration form

Question

I have expanded the standard user model with the UserProfile model with the following fields:

class UserProfile(models.Model):
    user = models.OneToOneField(User, related_name='profile')
    gender = models.CharField(max_length=30)
    info = models.CharField(max_length=30)

but when creating a new user using this form:

class SignupForm(forms.Form):
    first_name = forms.CharField(max_length=30, label='First name')
    last_name = forms.CharField(max_length=30, label='Last name')
    info = forms.CharField(max_length=30, label='info')
    def save(self, user):
        user.first_name = self.cleaned_data['first_name']
        user.last_name = self.cleaned_data['last_name']
        profile = UserProfile()
        profile.user = user     
        profile.info = self.cleaned_data['info']
        profile.save()
        user.profile = profile
        user.save()

"information" is always empty ('') in the database (like any other field except id). Standard attributes (first name, last name) are saved correctly.

I tried debugging and the error is not related to SQL because the query is invalid:

INSERT INTO "user_profile" ("user_id", "info") VALUES (17, '',
 '') RETURNING "user_profile"."id";

But, when I debug the value of user.profile.info using pdb, it works correctly:

(Pdb) user.profile.info
u'info passed from form'
