I don't understand what Django is asking for?

Question

Django

It was like this
There was a database, I added new columns to it and Django logically began to swear that there were no columns.
I deleted the database and the migration files performed the migration again and now it tells me that there is no table which should not be. What to do?

from django.shortcuts import render
from django.http import Http404, HttpResponseRedirect
from django.http import HttpResponse
from . models import allfilms

def index(request):
  allfilm = allfilms.objects.all()[:21]
  return render(request, 'main/homepage.html', <b>context = {'allfilms' : allfilm}</b>)

I selected a piece without which the page opens well, logically without data.
I have only one allfilms table but it asks for main_allfilms
