Django: A magical framework that can handle both front-end and back-end development!
Django is an efficient and scalable web application framework. It is able to support multiple web development models, including MVC and MTV, and can easily develop high-quality web applications. Django not only supports back-end development, but can also quickly build front-end interfaces and achieve flexible view display through template language. Django combines front-end development and back-end development into a seamless integration, so that developers do not have to learn the respective skills of front-end and back-end development and can easily complement each other.
This article will introduce the basic principles and functions of Django and provide some practical code examples.
1. The basic principles and functions of Django
Django is based on the Python language and uses some basic concepts and syntax of Python. The basic principle of Django is to adopt the MVT (Model-View-Template) development model, which is a variant of MVC.
MVT development model separates business logic, data model and view output, which facilitates development and maintenance. The specific process is:
1. The client issues a request (Request), and the route (URL) points to the corresponding view (View).
2. View is responsible for querying and processing data, and then passing the data to the template (Template).
3. The template (Template) renders the data into a specific view and returns the response (Response) to the client.
Django focuses on the design of the model layer. Developers using Django do not need to pay too much attention to the details of database operations. They only need to set the field type, validation rules (Validation), options, etc. when defining the model.
Django's front-end view is rendered using a template language, which uses Python code to directly render HTML templates. Templates bind and render data by specifying model classes or model instances, reflecting the pattern of the Django MVVM system.
2. Django code example
The following is a simple Django code example:
Step 1: Install and start Django
# 安装Django pip install Django # 创建一个新项目 django-admin startproject myproject # 启动Django开发服务器 python manage.py runserver
Step 2: Define the model
from django.db import models
class Book(models.Model):
name = models.CharField(max_length=100)
author = models.CharField(max_length=100)
pub_date = models.DateField()
price = models.DecimalField(max_digits=10, decimal_places=2)Step 3: Define the view
from django.http import HttpResponse
from django.template import loader
from .models import Book
def index(request):
books = Book.objects.order_by('-pub_date')[:5]
template = loader.get_template('book/index.html')
context = {
'books': books,
}
return HttpResponse(template.render(context, request))Step 4: Define the web page template
{% extends "base.html" %}
{% block content %}
<h1>Book list</h1>
{% if books %}
<ul>
{% for book in books %}
<li>Name: {{ book.name }} Author: {{ book.author }} Price: {{ book.price }}</li>
{% endfor %}
</ul>
{% else %}
<p>No books are available.</p>
{% endif %}
{% endblock %}Step 5: Configure routing
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
]Step 6: Run Django application
python manage.py runserver
Through the above steps, we can use Django to easily build a simple book list application. In summary, the Django framework provides a very efficient way to build web applications. It not only supports back-end development, but also provides some simple and easy-to-use methods for building front-end views. We believe that the Django framework will continue to be widely favored by web developers in the next few years!

Understanding React's Primary Function: The Frontend Perspective
Apr 18, 2025 am 12:15 AM
React's main functions include componentized thinking, state management and virtual DOM. 1) The idea of ??componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.
