So I am making an ecom site, and I am using Django. I am quite new and I am using a tutorial but have stepped off touch with it as I want to have 2 categories and maybe more on my website in the future. I want to be able to display them by their category, and I asked for help around my discord server and some people have tried to help and it does go through all my products however I have an if statement and that if statement gets ignored
So can anyone show me a way to display products with their category set as Specials only? Or hatbox only?
Store.Html
{% extends 'store/main.html' %}
{% load static %}
{% block content %}
<title>Store</title>
<h2>Our Stylish Hat Boxes - from the smallest to the largest.</h2>
<div class="row" style="padding-bottom: 5%;">
{% if products.category == Hatbox %}
{% for product in products %}
<div class="col-sm-4-fluid" style="margin-right: 5%;">
<div class="card" style="width:300px;">
<img class="card-img-top" src="{{product.imageURL}}" alt="Card image">
<div class="card-body">
<h5 style="display: inline-block; float:right;"><strong>
£ {{product.price|floatformat:2}}</strong></h5>
<h6 class="card-title">{{product.name}}</h6>
<a href="#" class="btn btn-primary">View</a>
</div>
</div>
</div>
{% endfor %}
{% endif %}
</div>
<h2>Something Special...</h2>
<div class="row" style="padding-bottom: 5%;">
{% for product in products %}
{% if products.categorys.name == "Specials" %}
<div class="col-sm-4-fluid" style="margin-right: 5%;">
<div class="card" style="max-width:300px;min-width: 50px;">
<img class="card-img-top" src="{{product.imageURL}}" alt="Card image">
<div class="card-body">
<h5 style="display: inline-block; float:right;"><strong>

<h6 class="card-title">{{product.name}}</h6>
<a href="#" class="btn btn-primary">View</a>

Answer
The if statement in the code won’t work as the products inside {% if products.categories == Hatbox %} does not have any categories since its not a single category object. The if statement is also missing quotes around Hatbox. Try this below:
Views
def store(request):
categorys = Category.objects.all()
context = {
'categorys': categorys,
}
return render(request, 'store/store.html', context)
store.html
{% for category in categorys %}
<h1>{{ category.nameOfCategory }}</h1>
{% for product in category.product_set.all %}
{{ product.name }}
{{ product.price }}
{{ product.size.size }}
{% endfor %}
{% endfor %}
