Why doesn't it display posts on the Django site?

Question

Django

Does not display posts on the main page of the site from the database, I don’t know what to do, I searched in the internet for options that don’t fit.
The problem is in the database, because if you just do a post, then everything is good, but if it’s in a cycle from the database, then it doesn’t display anything. Please tell me what to do?
PS There are no errors.

urls.py

from django.conf.urls import url, include
from . import views
from django.views.generic import ListView, DetailView
from main.models import AllFilms

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^$', ListView.as_view(queryset=AllFilms.objects.all().order_by("-date")[:12], template_name="main/homepage.html")),]

views.py

from django.shortcuts import render
from django.http import HttpResponse
from .models import AllFilms

def index(request):
  posts = AllFilms.objects.all()
  return render(request, 'main/homepage.html')
  return render(request, 'blog/index.html', context = {'posts' : posts})

homepage.py

{% extends "main/wrapper.html" %}

{% block content %}
  <h3>{{posts.title}}</h3>
  {% for film in posts %}
    <h3>{{film.title}}</h3>
  {% endfor %}

{% endblock %}

models.py

from django.db import models

class AllFilms(models.Model):
  title = models.CharField(max_length = 50)
  img_src = models.TextField()

  def __str__(self):
    return self.title

Answer 1

Your return with the context in which the posts are located does not work, because there is another return before it.
