What is Django?

Django is a secure and easy-to-learn web framework which follows MVT architecture inspired by MVC(Model-View-Controller) enabling us a quick development process with its built-in admin side, ORM(Object Relational Mapping), etc.

MVT here is Model-View-Template

The model is used to create and apply constraints on Tables/Collections in the Database. It looks like the image below.

class Orders(models.Model):
    order_id = models.AutoField(primary_key=True)
    user_id = models.ForeignKey(User, on_delete=models.CASCADE,default=None)
    product_ids = models.CharField(max_length=200,default=None)
    address_id = models.ForeignKey(Useraddress,on_delete=models.CASCADE,default = None)
    price = models.IntegerField()
    deliverycharges = models.IntegerField(null=True)
    orderdate = models.DateTimeField(auto_now_add=True)

The Views are functions or classes which accept HTTP requests and can process the request if needed and returns an HTTP response which may contain HTML files, HTTPResponse, JsonResponse, etc.

def viewCart(request):
    user =  User.objects.get(uid = request.user.uid) 
    cart = Cart.objects.filter(uid=user)
    if not cart:
        messages.error(request,"No Products found")

    context = {'cart' : cart}   
    return render(request, 'customer/cart.html' ,context=context)

The template is where the Whole HTML code is written and can be manipulated using Built-in Django Templating Engine

#Base.html which will be inherited in all the other html files so that you don't have to rewrite the same code over and over.


<!doctype html>
<html lang="eng">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Ecommerce | {% block title %}{% endblock title %}</title>
    {% block head %} 
    {% endblock head %}
  </head> 
<body> 
    {% block content %}
    {% endblock content %}
</body>
</html>

#This file inherits base.html and demonstrates use of block, include and for tags.


{% extends 'customer/base.html' %}
{% block title %} 
Cart
{% endblock title %}

{% block content %}
{% include 'customer/navbar.html' %}
<div class="container mt-5" >
        <div class="list-group">
            {% for product in cart %}
            <span class="list-group-item list-group-item-action mb-3"> 
                <a href="productdetails?id={{product.pid.pid}}">  {{product.pid.name}} </a>
                <a class="btn btn-sm btn-danger  float-end" href="removefromcart?id={{product.pid.pid}}">Remove from Cart</a>
            </span> 
            {% endfor %}
        </div>
        <div>
            <a href="checkout/address?source=cart" class="btn btn-success ">Checkout</a>
        </div>
</div>
{% endblock content %}

The controller in Django is handled by Django itself.
