How to use Python to implement the advertising management function of CMS system

With the rapid development of the Internet, websites have become one of the important channels for publicity and promotion in all walks of life. As a common method of online promotion, advertising plays an important role in the profitability and user experience of the website. In order to facilitate website administrators to manage and display advertisements, many websites use CMS (Content Management System) systems to implement advertising management functions. This article will introduce how to use the Python programming language to implement the advertising management function of a simple CMS system.

1. Introduction to CMS system

CMS system is a software used to manage and publish content. It can be used to create, edit and publish website content. It provides a user-friendly interface that allows webmasters to easily manage the content, layout, and functionality of the website. Through the CMS system, advertising administrators can easily add, edit and delete ads, and control the placement, frequency and style of ads.

2. Development environment preparation

Before writing code, we need to prepare a suitable development environment. The following are some commonly used Python development tools and libraries:

1. Python interpreter: Python 3.x version is recommended.
2. Flask Framework: A lightweight Python web development framework to build web applications quickly and easily.
3. SQLAlchemy: A popular Python ORM (Object Relational Mapping) library for operating databases.
4. SQLite database: A lightweight relational database suitable for small applications.

You can choose other suitable tools and libraries based on your needs and personal preferences. Next, we will use Flask and SQLAlchemy to implement advertising management functions.

3. Create a Flask application

First, we need to create a Flask application. You can follow the steps below:

1. Install the Flask library:

pip install flask

2. Create a Python script named app.py and import the necessary modules:

from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///ads.db'
db = SQLAlchemy(app)

In the above code, we imported the Flask and SQLAlchemy libraries and created a Flask application. app.config['SQLALCHEMY_DATABASE_URI'] is used to set the connection string of the database. Here we use the SQLite database.

4. Create an advertising model

Next, we need to create an advertising model to represent advertising information. In Python, we can represent a database table by defining a class that inherits from SQLAlchemy.Model.

class Ad(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(128))
    content = db.Column(db.String(512))
    start_date = db.Column(db.Date)
    end_date = db.Column(db.Date)
    position = db.Column(db.Integer)
    status = db.Column(db.Integer)

In the above code, we define an Ad class, which contains various attributes of the advertisement, such as title, content, start date, end date, location and status, etc. The id is designated as the primary key, ensuring the uniqueness of each ad.

5. Create a database table

After creating the advertising model, we need to use the db.create_all() method to create the corresponding database table.

db.create_all()

6. Writing advertising management functions

Next, we can start writing advertising management functions. We need to implement the function of adding, deleting, modifying and checking advertisements. Here are some commonly used functions and sample code:

1. Add Ads

@app.route('/ads/add', methods=['GET', 'POST'])
def add_ad():
    if request.method == 'POST':
        ad = Ad()
        ad.title = request.form['title']
        ad.content = request.form['content']
        ad.start_date = request.form['start_date']
        ad.end_date = request.form['end_date']
        ad.position = request.form['position']
        ad.status = request.form['status']
        db.session.add(ad)
        db.session.commit()
        return redirect(url_for('list_ads'))
    else:
        return render_template('add_ad.html')

In the above code, we handle it through the '/ads/add' route and POST method A request to add an ad. If it is the POST method, the various properties of the ad are obtained from the form and added to the database.

2. Edit ads

@app.route('/ads/edit/<int:ad_id>', methods=['GET', 'POST'])
def edit_ad(ad_id):
    ad = Ad.query.get(ad_id)
    if request.method == 'POST':
        ad.title = request.form['title']
        ad.content = request.form['content']
        ad.start_date = request.form['start_date']
        ad.end_date = request.form['end_date']
        ad.position = request.form['position']
        ad.status = request.form['status']
        db.session.commit()
        return redirect(url_for('list_ads'))
    else:
        return render_template('edit_ad.html', ad=ad)

In the above code, we use the '/ads/edit/048ad4750fb7cf4b15128bd9f7912e14' route and GET/POST method to handle editing ads. ask. If it is a GET method, the advertisement is queried from the database and passed to the template for display. If it is the POST method, the various properties of the advertisement are updated and saved to the database.

3. Delete ads

@app.route('/ads/delete/<int:ad_id>', methods=['POST'])
def delete_ad(ad_id):
    ad = Ad.query.get(ad_id)
    db.session.delete(ad)
    db.session.commit()
    return redirect(url_for('list_ads'))

In the above code, we handle the request to delete ads through the '/ads/delete/048ad4750fb7cf4b15128bd9f7912e14' route and POST method. Query the advertisement from the database through ad_id and delete it.

4. Get the ad list

@app.route('/ads')
def list_ads():
    ads = Ad.query.all()
    return render_template('list_ads.html', ads=ads)

In the above code, we handle the request to get the ad list through the '/ads' route. All ads are queried from the database through the Ad.query.all() method and passed to the template for display.

7. Create HTML templates

Finally, we need to create some HTML templates to render and display advertising management functions. Here are some commonly used templates and sample code:

1. add_ad.html

<form method="post" action="/ads/add">
    <label>标题</label>
    <input type="text" name="title">
    <!-- 其他属性的输入框 -->
    <button type="submit">保存</button>
</form>

2. edit_ad.html

<form method="post" action="/ads/edit/{{ad.id}}">
    <label>标题</label>
    <input type="text" name="title" value="{{ad.title}}">
    <!-- 其他属性的输入框 -->
    <button type="submit">保存</button>
</form>

3. list_ads.html

<table>
    <tr>
        <th>标题</th>
        <!-- 其他属性的表头 -->
        <th>操作</th>
    </tr>
    {% for ad in ads %}
    <tr>
        <td>{{ad.title}}</td>
        <!-- 其他属性的表格 -->
        <td>
            <a href="/ads/edit/{{ad.id}}">编辑</a>
            <form method="post" action="/ads/delete/{{ad.id}}" style="display:inline;">
                <button type="submit">删除</button>
            </form>
        </td>
    </tr>
    {% endfor %}
</table>

In the above code, we use the template engine provided by Flask, which can easily pass dynamic data to HTML templates for rendering and display.

8. Run the program

Finally, we need to run the script in the terminal to start the Flask application.

python app.py

Enter http://localhost:5000 in the browser to access the advertising management function page.
