Manager isn't available; 'auth.User' has been swapped for 'accounts.User'

Question

I have created a custom user model 'User' and have declared in settings.py as AUTH_USER_MODEL Also i have two other models consumer and workman which has an onetoone relation with my custom user. i created two forms for registering customer and workman but as i fill form(it doesnt even check validation) and submit, it says: Manager isn't available; 'auth.User' has been swapped for 'accounts.User'

models.py:

from django.contrib.auth.models import AbstractUser
from django.contrib.auth import  get_user_model

# Create your models here.

class User(AbstractUser):

    class Types(models.TextChoices):
        CONSUMER = "CONSUMER" , "Consumer"
        WORKMAN = "WORKMAN" , "Workman"
    type = models.CharField(max_length=20,choices=Types.choices,default=Types.WORKMAN)

    is_consumer = models.BooleanField(default=False)
    is_workman = models.BooleanField(default=False)

class Consumer(models.Model):
    user = models.OneToOneField(get_user_model(),on_delete=models.CASCADE,primary_key=True)
    location = models.CharField(max_length=100)

class Workman(models.Model):
    user = models.OneToOneField(get_user_model(),on_delete=models.CASCADE,primary_key=True)
    contact = models.CharField(max_length=100)

views.py:

from .forms import ConsumerCreationForm, WorkmanCreationForm
from .models import Workman,Consumer

class consumersignupview(CreateView):
    model = Consumer
    form_class = ConsumerCreationForm
    template_name = 'accounts/register.html'
    success_url = '/'


class workmansignupview(CreateView):
    model = Workman
    form_class = WorkmanCreationForm
    template_name = 'accounts/register.html'
    success_url = '/'

forms.py:

from django.contrib.auth.forms import UserCreationForm
from django import forms
from .models import Consumer,Workman

class ConsumerCreationForm(UserCreationForm):
    location = forms.CharField( max_length=100, required=False)
    class meta(UserCreationForm.Meta):
        model = Consumer
        
class WorkmanCreationForm(UserCreationForm):
    contact = forms.CharField(max_length=100)

    class meta(UserCreationForm.Meta):
        model = Workman

Share the *full* traceback. Normally the Django error page has a function to turn the error in a text format that includes settings, traceback, etc. — Willem Van Onsem, Nov 11 '21 at 18:40

This error is a repeat of this issue. You are likely importing the wrong user model somewhere.

Yeah i went through those solutions but there are no any 'User' mentioned anywhere in my code so the solution didnt help much. – Rupesh Chaulagain Nov 11 '21 at 18:50
Hmm, how are you attaching a `User` to the consumer? It seems to be a required field based on the model, but I don't see you assign it anywhere in the view. You also don't need to import `get_user_model()` because the model is in the same file. – dichter Nov 11 '21 at 19:35
