How to use Python to develop the online editor function of the CMS system

With the development of the Internet, the CMS system has become the first choice for many website developers. As a content management system, it helps users easily create, edit and publish website content. The online editor function is an essential component in the CMS system, which allows users to edit and save content directly on the website. This article will introduce how to use Python to develop the online editor function of a CMS system and provide some code examples.

Before we start, we need to understand some basic concepts and tools. First of all, Python is a simple yet powerful programming language that is widely used in web development. Secondly, we need to choose a suitable development framework to build the CMS system. Django is a popular Python web framework that provides many powerful features and tools. Finally, we need to choose a suitable rich text editor to implement online editing functions. Summernote is an easy-to-use rich text editor that integrates well with Django.

First, we need to install Python and Django. Install them by running the following command in the terminal:

$ pip install python
$ pip install django

Copy after login

Once the installation is complete, we can create a new Django project:

$ django-admin startproject cms

Copy after login

Then, we need to create a new Django application:

$ python manage.py startapp editor

Copy after login

Next, we need to configure some basic information in the Django settings file. Open the settings.py file and add the following configuration:

INSTALLED_APPS = [
    ...
    'editor',
    'django_summernote',
    ...
]

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

Copy after login

Then, we need to configure URL routing in the urls.py file. Open the urls.py file and add the following configuration:

from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    ...
    path('summernote/', include('django_summernote.urls')),
    ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Copy after login

Next, we need to create a model to store the editor content. Open the models.py file and add the following code:

from django.db import models
from django_summernote.fields import SummernoteTextField

class Page(models.Model):
    title = models.CharField(max_length=100)
    content = SummernoteTextField()

Copy after login

Then, we need to run the database migration command to create the database table:

$ python manage.py makemigrations
$ python manage.py migrate

Copy after login

Next, we need to create A view to handle editor functionality. Open the views.py file and add the following code:

from django.shortcuts import render
from .models import Page

def editor(request, page_id):
    page = Page.objects.get(id=page_id)
    
    if request.method == 'POST':
        page.content = request.POST.get('content')
        page.save()
    
    return render(request, 'editor.html', {'page': page})

Copy after login

Then, we need to create an editor template to implement the online editor function. Create an HTML file called editor.html and add the following code:

{% extends "base.html" %}

{% block content %}
    <h1>{{ page.title }}</h1>
    <form method="post" action="">{% csrf_token %}
        {{ page.content|safe }}
        <br>
        <button type="submit">保存</button>
    </form>
{% endblock %}

Copy after login

Finally, we need to create a base template to render the website content. Create an HTML file named base.html and add the following code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>CMS系统</title>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/summernote@0.8.18/dist/summernote-bs4.css">
    <script src="https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/summernote@0.8.18/dist/summernote-bs4.js"></script>
    <script>
        $(document).ready(function() {
            $('textarea').summernote({
                height: 300
            });
        });
    </script>
</head>
<body>
{% block content %}
{% endblock %}
</body>
</html>

Copy after login

Now, we have completed the development of the online editor function of the CMS system. Start the development server by executing the following command:

$ python manage.py runserver

Copy after login

Then, visit http://localhost:8000/editor/1/ in the browser to edit and save using the online editor function Page content.
