##View

def index(request):

products = Product.objects.all()

category = get_list_or_404(Category)

cat = Category.objects.filter(pk = id)

return render(request, 'shop/index.html', locals())

##product_list Page

<h2>Categories</h2>

{% if cat %}

<ul>

{% for c in cat %}

<li>

<a href="{% url 'product-list' %}"> {{c.name}}</a>

</li>

{% for product in cat.get_product %}

<p> {(product.name}}</p>

{% endfor %}

{% endfor %}

</ul>

What is the name of the field in your model?  ie:  Title, Name, etc....  so one option would be product.title   or product.name....

can you just put your model in here?

from django.db import models

from django.shortcuts import reverse

OK, this is CLOSE and it may even work....maybe someone else can correct it, because I may have category/product backwards, and I put a filter in there so you can search for a product by attribute, but you'll have to tweak it...

category_view.html

{% extends "base.html" %}
{% block content %}
<h3 align="center"> Products in a Category </h3>
<form method="get">
    {{ object_list.form.as_p }}
  <button type="submit">Search</button>
</form>
{% for object in object_list.qs%}
{% include 'category-inline.html'%}
{% endfor %}
{% endblock %}




category_inline.html

<div class='col-80 col-md-100 mb-1 mx-auto'>
<div class='card'>
  <div class='card-body'> 
<h5 class = 'card-title'>       
<p>{{object.name}}-{{object.slug}}</p>      
{% for product in object.category.category.all %}          
{{product.name}}--{{product.slug}}--{{product.brand}}--
{{product.available}}{{product.stock}}                 
{% endfor %}


views.py

from .filters import ProductFilter

def category_view(request):  
my_title = "Products"  
qs = Category.objects.prefetch_related('category__category')  
category_list = ProductFilter(request.GET, queryset=qs)  
template_name = 'category_view.html'  
context = {'object_list': category_list,"title":my_title}  
return render (request, template_name, context)



filters.py


class ProductFilter(django_filters.FilterSet):
category__name = django_filters.CharFilter(lookup_expr='icontains',label='Product Name contains')
class Meta:      
model = Product
fields = {

        }

I would suggest not using locals(). You only have three variables to pass through to your template.

Thanks it was helpful learned about django-filter,
But i just want it simple as in , i already have the list of categories displaying, i just need something that when the customer click on a particular category name the customer will get redirected to another page with all the list of products under that category

Hi. 

Please don't hijack other people threads but start a new one.

No. Absolutely no. You can write plain backend code for example by using JSON respondses.

Though if you want to write full web sites HTML and CSS greatly helps.

2. what are the advantages and disadvantages of django?

A good friendly community. And it's written in Python. Best programming language ever.

3. how it is useful?

In my opionion it's very fast tool to make ideas to real dynamic web apps.

Also there are tons of Python libraries that you can leverage plus huge amount apps (kind of plugins) you can use in you Django projects to help making things even faster.

4. any best resources that u can provide for me?

Do tutorials. Django Girls do provide excellent tutorial to get started.

 thanks in advance...!
