Here&#8217;s how you can define models and relationships:<\/span><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\"> Open the `models.py` file in your Django app directory.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Import the necessary modules: `from django.db import models`.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Define your models as Python classes, with each class representing a database table.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Define attributes (fields) for each model class, such as CharField, IntegerField, ForeignKey, etc., to represent the different types of data stored in the table.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Define relationships between models using ForeignKey, OneToOneField, ManyToManyField, or other appropriate fields.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Look at the example:<\/span><\/p>\n<pre class=\"theme:turnwall height-set:true height:250 nums:false lang:default decode:true\">python\r\n\r\nfrom django.db import models\r\n\r\nclass Category(models.Model):\r\n\r\n\u00a0\u00a0\u00a0\u00a0name = models.CharField(max_length=100)\r\n\r\nclass Product(models.Model):\r\n\r\n\u00a0\u00a0\u00a0\u00a0name = models.CharField(max_length=200)\r\n\r\n\u00a0\u00a0\u00a0\u00a0category = models.ForeignKey(Category, on_delete=models.CASCADE)\r\n\r\n\u00a0\u00a0\u00a0\u00a0price = models.DecimalField(max_digits=10, decimal_places=2)<\/pre>\n<p><span style=\"font-weight: 400;\">In this example, we have defined two models: `Category` and `Product`. The `Product` model has a ForeignKey relationship with the `Category` model, representing a one-to-many relationship (one category can have multiple products).<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"23-Implementing-Django-Views\"><\/span><span style=\"font-weight: 400;\">2.3 Implementing Django Views:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h4><span class=\"ez-toc-section\" id=\"Handling-HTTP-requests-and-responses\"><\/span><span style=\"font-weight: 400;\">Handling HTTP requests and responses:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">Views in Django handle HTTP requests and return responses.

Here&#8217;s how to implement views:<\/span><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\"> Open the `views.py` file in your Django app directory.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Import the necessary modules: `from django.shortcuts import render, get_object_or_404, redirect`.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Define functions or classes for your views. Functions are used in function-based views, while classes are used in class-based views.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Write the logic for handling the request, which may involve querying the database, processing data, and preparing a response.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Return a response, which can be an HTML template rendered with data, a redirect to another URL, or other appropriate responses.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Example of a function-based view:<\/span><\/p>\n<pre class=\"theme:turnwall height-set:true height:250 nums:false lang:default decode:true\">python\r\n\r\nfrom django.shortcuts import render, get_object_or_404\r\n\r\nfrom .models import Product\r\n\r\ndef product_detail(request, product_id):\r\n\r\nproduct = get_object_or_404(Product, id=product_id)\r\n\r\nreturn render(request, 'product_detail.html', {'product': product})<\/pre>\n<p><span style=\"font-weight: 400;\">In this example, the `product_detail` function retrieves a product object from the database based on the provided `product_id`.

They allow you to combine static HTML with dynamic content from the backend. Here&#8217;s how to create and use templates:<\/span><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\"> Create a `templates` directory in your Django app directory (if not already present).<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Inside the `templates` directory, create HTML template files with the `.html` extension.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Add template tags and filters to inject dynamic content and perform logic within the templates.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Use Django&#8217;s template language to access variables, loop through data, and apply conditional logic.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Example template (`product_detail.html`):<\/span><\/p>\n<pre class=\"theme:turnwall height-set:true height:250 nums:false lang:default decode:true \">html\r\n\r\n&lt;h1&gt;{{ product.name }}&lt;\/h1&gt;\r\n\r\n&lt;p&gt;Category: {{ product.category.name }}&lt;\/p&gt;\r\n\r\n&lt;p&gt;Price: ${{ product.price }}&lt;\/p&gt;<\/pre>\n<p><span style=\"font-weight: 400;\">In this example, we access the `product` object&#8217;s attributes using template variables enclosed within `{{ }}`.
