Use Webman to implement the user feedback and comment system of the website

Introduction:
In modern society, websites have become a way for people to obtain information, communicate and express opinions important tool. In order to better interact with users, user feedback and comment systems are an integral part of the website. This article will introduce how to use the Webman framework to implement a simple but powerful user feedback and comment system, giving users a better sense of participation and communication platform.

1. Webman Framework
Webman is a lightweight Web framework based on Python, which is simple to use and has good scalability. It provides routing, middleware, templates and other functions, and is a tool very suitable for rapid development of web applications.

2. Design Ideas
The user feedback and comment system can be considered as an interactive process: the user fills in the feedback or comment content, and the system receives the content and stores and displays it. In order to realize this process, we can use a database to store user feedback and comment content, and use the Webman framework to implement user interface and data interaction.

3. Database design
We can use SQLite database to store user feedback and comments. For the sake of simplicity, we design a simple table structure, including four fields: id, username, content and time. Among them, id is a unique identifier, username is the user's nickname, content is the specific content of the feedback or comment, and time is the time of submission.

The following is a code example to create a database table:

import sqlite3

# 创建数据库连接
conn = sqlite3.connect('feedback.db')

# 创建游标对象
cursor = conn.cursor()

# 创建表
cursor.execute('''
    CREATE TABLE IF NOT EXISTS feedback (
        id INTEGER PRIMARY KEY AUTOINCREMENT,
        username VARCHAR(50),
        content TEXT,
        time TIMESTAMP DEFAULT (datetime('now', 'localtime'))
    )
''')

# 提交更改
conn.commit()

# 关闭连接
conn.close()

Copy after login

4. Webman routing and interface design
First, we need to set up Webman routing so that users can access our feedback and Comments page. Here is a code example for setting up routing:

from webman import Webman

app = Webman()

# 显示反馈和评论页面
@app.route('/')
def index():
    return app.render_template('index.html')

# 处理用户提交的反馈或评论
@app.route('/submit', methods=['POST'])
def submit():
    # 获取用户提交的内容
    username = app.request.form.get('username')
    content = app.request.form.get('content')
    
    # 将内容插入数据库
    conn = sqlite3.connect('feedback.db')
    cursor = conn.cursor()
    cursor.execute('INSERT INTO feedback (username, content) VALUES (?, ?)', (username, content))
    conn.commit()
    conn.close()
    
    # 返回提交成功信息
    return '提交成功！'

Copy after login

Next, we need to create an HTML template to display the feedback and comments page and accept input from the user. The following is a simple HTML template example:

<!DOCTYPE html>
<html>
<head>
    <title>用户反馈和评论系统</title>
</head>
<body>
    <h1>用户反馈和评论系统</h1>
    
    <h2>用户反馈</h2>
    <form action="/submit" method="post">
        <label for="username">昵称：</label>
        <input type="text" id="username" name="username" required><br>
        <label for="content">内容：</label>
        <textarea id="content" name="content" required></textarea><br>
        <input type="submit" value="提交">
    </form>
    
    <h2>评论列表</h2>
    {% for comment in comments %}
        <p>昵称：{{ comment[1] }}</p>
        <p>内容：{{ comment[2] }}</p>
        <p>时间：{{ comment[3] }}</p>
        <hr>
    {% endfor %}
</body>
</html>

Copy after login

In the above HTML template, we use the syntax of the template engine to dynamically display the list of user-submitted feedback and comments. Among them, comments are feedback and comment data obtained from the database and rendered into the page through traversal.

5. Run and test
Save the above code to a .py file, and then run the file to start the Webman service. Open the browser and enter "http://localhost:8000" in the address bar to access the user feedback and comments page. After entering the nickname and content, click the submit button to store the user's feedback and comment content in the database. Refresh the page to see a list of submitted feedback and comments.

6. Summary:
This article introduces how to use the Webman framework to implement a simple but powerful user feedback and comment system. By designing the database table structure, setting up Webman routing and writing HTML templates, we can store and display user feedback and comment data. Such a system can effectively improve user participation and interactivity of the website, and provide users with a better communication platform. In actual applications, the system functions can be further expanded and optimized according to needs, such as adding user login, permission management, etc. I hope this article can provide some reference and help for developers interested in developing user feedback and comment systems.
