KeyError: 'include'

After this, i can see below two tables created in database

django_migrations
django_content_type

My Model is below:

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

class UserMaster(models.Model):
    user = models.OneToOneField(User, on_delete = models.CASCADE)

    # Additional fields
    confirm_password = models.CharField(max_length=10)

    def __str__(self):
        return self.user.username

Below is Forms.py

from django import forms
from django.contrib.auth.models import User
from retail_forms.models import UserMaster

class UserForm(forms.ModelForm):
    password = forms.CharField(widget = forms.PasswordInput())
    first_name = forms.CharField(required=True)
    last_name = forms.CharField(required=True)

    class Meta():
        model = User
        fields = ('first_name','last_name','email','username','password')

class UserMasterForm(forms.ModelForm):
    confirm_password = forms.CharField(required=True)
    class Meta():
        model = UserMaster
        fields = ('confirm_password',)

Django version: 3.2

Can someone help.

@WillemVanOnsem - Added models.py and forms.py file. Not sure if this is you are asking. I am very new to django, so not up to the mark. — Ronak

django-mssql-backend isn't compatible with django 3.2 (at time of writing). Try 3.0, or 3.1 with the mssql-django backend (see: github.com/microsoft/mssql-django/issues/25) — Tim Nyborg

This issue is patched in pre-release version 1.0rc1 of mssql-django. GitHub issue

I recommend using mssql-django over django-pyodbc, django-pyodbc-azure-2019 or django-mssql-backend. As it's supported by microsoft and has better support imo.

To fix:

Install mssql-django pip install mssql-django==1.0rc1
Change the database engine in settings.py

DATABASES = {
        'default': {
            'ENGINE': 'mssql',
            ...
        }
    }

Using mssql-django works for me. There is a collision in django-environ, as it translates schema mssql:// into incorrect engine.

Dear I play with this alot and found that issue is django-pyodbc

I do the following:

Uninstall this using pip uninstall django-pyodbc or pip3 uninstall django-pyodbc (for Linux)
Install this using pip install django-pyodbc-azure-2019 or pip3 install django-pyodbc-azure-2019 (for Linux)

My Issue is resolved and hope your app will run smoothly after this. :-)

It is related with Django version. New version has issues, we need to downgrade. ` pip install django-pyodbc-azure-2019` automatically installs older Django version, that's way how problem is solved.

Diagnosis :
This is an incompatibility issue between django-mssql-backend and django. django-mssql-backend supports Django 3.0+ only.
Solution :
Rollback to Django 3.0.14 and then run your migrations. It works fine.
Alternatively, you can try this fork supporting 3.2 : https://github.com/microsoft/mssql-django/issues/50

Changing the Engine name work for me:

# settings.py
DATABASES = {
    "default": {
        "ENGINE": "mssql",
        "NAME": "DATABASE_NAME",
        "USER": "USER_NAME",
        "PASSWORD": "PASSWORD",
        "HOST": "HOST_ADDRESS",
        "PORT": "1433",
        "OPTIONS": {"driver": "ODBC Driver 17 for SQL Server", 
        },
    },
}
