I'm making a website using Django and Bootstrap but I'm unable to find out the error.

This is

from django.db import models

# Create your models here.

class Product(models.Model):
    product_id = models.AutoField
    product_name = models.CharField(max_length=50)
    category = models.CharField(max_length=50,default="")
    subcategory = models.CharField(max_length=50,default="")
    price = models.IntegerField(default=0)
    desc = models.CharField(max_length=300)
    pub_date= models.DateField()
    image = models.ImageField(upload_to="shop/images",default="")

    def __str__(self):
        return self.product_name

This is
from django.shortcuts import render
from .models import Product
from math import ceil
# Create your views here.
from django.http import HttpResponse
def index(request):
    # products= Product.objects.all()
    # n= len(products)
    # nSlides= n//6 + ceil((n/6) - (n//6))
    # params={'no_of_slides':nSlides, 'range':range(1,nSlides), 'product': products}
    allProds = []
    catprods = Product.objects.values('category','id')
    cats = {item['category'] for item in catprods}
    for cat in cats:
        prod = Product.objects.filter(category = cat)
        n = len(prod)
        nSlides = n // 6 + ceil((n / 6) - (n // 6))
        allProds.append([prod,range(1 , nSlides), nSlides])
        params = {'allProds': allProds}
    return render(request,"shop/index.html", params)
def about(request):
    return render(request , 'shop/about.html')
def contact(request):
    return HttpResponse("We are at contact")
def tracker(request):
    return HttpResponse("We are at tracker")
def search(request):
    return HttpResponse("We are at search")
def productView(request):
    return HttpResponse("We are at product view")
def checkout(request):
    return HttpResponse("We are at checkout")

This is
from django.contrib import admin
from django.urls import path
from . import views

urlpatterns = [
    path("",views.index, name ="ShopHome"),
    path("about/",views.about,name="About us"),

This is index.html

What I have tried:

Saying, "not working", is the single most useless comment we see on these forums. And just dumping all your code and expecting us to a) work out what the problem is and where it occurs, and b) provide a full solution, is rather rude.

So, please use the Improve question link below your question, and add complete details of the problem and exactly where it occurs.
