Я работаю над проектом django, в котором я расширил таблицу auth_user для добавления операторов, и это даст ошибку

Question

MY HTML CODE ===

Это мой html код для добавления оператора в базу данных

{% extends 'Adminside/master.html' %}
{% block content %}

МОЙ КОД ПРОСМОТРА =====

Это мой код просмотров для ввода данных

def addoperator(request):
        if request.method=="POST":
            opera = User.objects.create_user(
            username=request.POST['name'],
            email=request.POST['email'],
            password=request.POST['password']

        )
            s=Operator()
            s.user=opera 
            s.phonenumber=request.POST['number']
            s.gender=request.POST['gender']
            s.address=request.POST['address']
            s.picture=request.FILES['userimage']
            s.document=request.FILES['document']
            s.save()
            return render(request,'Adminside/addoperators.html')
        else:
            return render(request,'Adminside/addoperators.html')

МОЙ КОД МОДЕЛЕЙ ===

МОЯ ОШИБКА ПРИ РАБОТЕ НА ЭТОМ

OperationalError at /addoperator
table Adminside_operator has no column named user_id
Request Method: POST
Request URL:    http://127.0.0.1:8000/addoperator
Django Version: 2.2.4
Exception Type: OperationalError
Exception Value:    
table Adminside_operator has no column named user_id
Exception Location: C:\Users\lenovo\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\db\backends\sqlite3\base.py in execute, line 383
Python Executable:  C:\Users\lenovo\AppData\Local\Programs\Python\Python37-32\python.exe
Python Version: 3.7.4
Python Path:    

Это основная ошибка, из-за которой я застрял на этой штуке, и в этой модели кода я заботился только о пользовательском поле, но выдает ошибку о user_id, которую я не понимаю, откуда она взялась, любая помощь будет буду признателен ...... Спасибо
