categories/models.py
from django.db import models
from treebeard.mp_tree import MP_Node
class Category(MP_Node):
title = models.CharField(max_length=50)
slug = models.SlugField(unique=True)
node_order_by = ['title']
class Meta:
verbose_name = 'category'
verbose_name_plural = 'categories'
def __str__(self):
return 'Category: {}'.format(self.title)
categories/views.py
from django.views.generic import DetailView
from .models import Category
class CategoryDetailView(DetailView):
model = Category
context_object_name = 'category'
template_name = 'categories/category_detail.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context["products_in_category"] = self.object.products.filter(active=True)
return context
category_detail.html
.....
{% for p in products_in_category %}
<h2><a href="{{ p.get_absolute_url }}">{{ p.title }}</a></h2>
.....
The code above works well to display products that belong to a specific category but I would also be able to display the products that belong to its descendants.
Example:
shoes
├── sneakers
│ ├── laced sneakers
│ └── non-laced sneakers
If I'm on the category page for sneakers I would want to be able to see products related to both Laced Sneakers and Non-laced Sneakers.
My thought was that the get_context_data could look something like this
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context["products_in_category"] = self.object.get_descendants().products.filter(active=True)
return context
But unfortunately, that did not work out.
I was thinking about using ListView instead but the category page will have a description describing the category and for that reason, I figure DetailView would be a better choice.
What do you guys think is the best approach?
