Как вывести данные из БД SQLite Django на html страницу?

Файл models.py

from django.db import models
class Manufacturer(models.Model):
    number = models.IntegerField(verbose_name="Номер")
    manufacturer = models.CharField(max_length=20, verbose_name="Производитель")
    def __str__(self):
        return self.manufacturer
    class Meta:
        verbose_name = "Производитель"
        verbose_name_plural = "Производители"
class Catalog(models.Model):
    number = models.IntegerField(verbose_name="Номер")
    manufacturer = models.ForeignKey(Manufacturer, on_delete=models.CASCADE, verbose_name="Производитель")
    types = models.CharField(max_length=50, verbose_name="Тип оборудивания")
    model = models.CharField(max_length=50, verbose_name="Модель")
    description = models.CharField(max_length=1000, verbose_name="Описание")
    information = models.CharField(max_length=1000, verbose_name="Информация")
    def __str__(self):
        return self.model
    class Meta:
        verbose_name = "Каталог"
        verbose_name_plural = "Каталоги"

Файл views.py

from django.shortcuts import render
import requests
from django.views.generic import ListView, DetailView, TemplateView
from Tenda.models import Manufacturer, Catalog
def index(request):
    return render(request, 'Tenda/index.html')
class CatalogView(ListView):
    model = Catalog
    template_name = 'catalog.html'
class CatalogDetail(DetailView):
    model = Catalog
    template_name = 'catalog.html'

Файл catalog.html

{% extends "Tenda/wrapper.html" %}
{% block content %}
    {% for val in values %}
        <!-- Таблица каталога-->
        <table class="table">
          <thead class="thead-dark">
            <tr>
              <th scope="col">#</th>
              <th scope="col">Номер</th>
              <th scope="col">Производитель</th>
              <th scope="col">Тип</th>
              <th scope="col">Модель</th>
              <th scope="col">Описание</th>
              <th scope="col">Информация</th>
            </tr>
          </thead>
          <tbody>
            {% for catalog in catalogs %}
            <tr>
              <th scope="row">1</th>
              <td>{{ catalog.number }}</td>
              <td>{{ catalog.manufacturer }}</td>
            </tr>
            {% endfor %}
          </tbody>
        </table>
        {{val}}
    {% endfor %}
{% endblock %}
