Allauth will not save additional fields

Question

I have been trying to extend my allauth signup form but cannot seem to get it working, I receive no error messages and everything appears to work fine except all my additional fields do not get saved. Please tell me if you can see what I am doing wrong, thanks!

Models -

from django.db import models
from django.contrib.auth.models import User

You are adding new attributes on the user object instead of creating a new EmployerProfile. I believe the following code is what you are trying to achieve:

class SignupForm(forms.Form):
    # ...
    def signup(self, request, user):
        EmployerProfile.objects.create(
            user=user,
            home_number=self.cleaned_data['home_number'],
            mobile_number=self.cleaned_data['mobile_number'],
            business_name=self.cleaned_data['business_name'],
            business_address_number=self.cleaned_data['business_address_number'],
            business_address_street=self.cleaned_data['business_address_street'],
            business_address_region=self.cleaned_data['business_address_region'],
            business_address_suburb=self.cleaned_data['business_address_suburb'],
            business_address_postcode=self.cleaned_data['business_address_postcode'],
            business_industry=self.cleaned_data['business_industry']
        )
