Implementing event management system using WebMan technology
Using WebMan technology to build an event management system
With the rapid development of the Internet, enterprise and organizational management have become increasingly complex, and event management has become particularly important. To improve efficiency and accuracy, many businesses and organizations are beginning to use incident management systems to help them track, record, and handle incidents. This article will introduce how to use WebMan technology to build a powerful event management system.
WebMan is an open source web framework based on Python that provides many powerful tools and features to help developers quickly build efficient web applications. We will use WebMan to build the back-end of the event management system, and use HTML, CSS and JavaScript to implement the front-end interface.
First, we need to create a basic database to store event information. In this example, we will use a SQLite database to simplify configuration. We can use Python's built-in SQLite module to operate the database. The code is as follows:
import sqlite3
# 连接到数据库
conn = sqlite3.connect('event.db')
# 创建事件表
conn.execute('''CREATE TABLE event
(id INTEGER PRIMARY KEY AUTOINCREMENT,
title TEXT NOT NULL,
description TEXT NOT NULL,
status TEXT NOT NULL)''')
# 关闭数据库连接
conn.close()In this code, we first import the sqlite3 module and then use connect() The function connects to a SQLite database file named event.db. Next, we use the execute() function to execute a SQL command to create a table named event, which contains id, title## Four fields: #, description and status. Finally, we use the close() function to close the database connection.
index.html, the code is as follows:
<!DOCTYPE html>
<html>
<head>
<title>事件管理系统</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.0/dist/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<h1 id="事件管理系统">事件管理系统</h1>
<div id="eventList"></div>
<form id="eventForm">
<div class="mb-3">
<label for="title" class="form-label">标题</label>
<input type="text" class="form-control" id="title" required>
</div>
<div class="mb-3">
<label for="description" class="form-label">描述</label>
<textarea class="form-control" id="description" rows="3" required></textarea>
</div>
<button type="submit" class="btn btn-primary">提交</button>
</form>
</div>
<script src="https://cdn.jsdelivr.net/npm/jquery@3.6.0/dist/jquery.min.js"></script>
<script src="script.js"></script>
</body>
</html>div element placeholder as the container for the event list, followed by a form for entering event information. The form contains an input box, a text box, and a submit button.
script.js with the code as follows:
$(function() {
// 加载事件列表
$.ajax({
url: 'api/events',
type: 'GET',
success: function(events) {
var $eventList = $('#eventList');
// 渲染事件列表
$.each(events, function(index, event) {
$eventList.append('<div>' + event.title + '</div>');
});
}
});
// 提交事件表单
$('#eventForm').submit(function(e) {
e.preventDefault();
var $form = $(this);
var title = $('#title').val();
var description = $('#description').val();
// 创建事件
$.ajax({
url: 'api/events',
type: 'POST',
data: {
title: title,
description: description
},
success: function() {
// 清空表单并重新加载事件列表
$form.trigger('reset');
$('#eventList').empty();
$.ajax({
url: 'api/events',
type: 'GET',
success: function(events) {
var $eventList = $('#eventList');
// 渲染事件列表
$.each(events, function(index, event) {
$eventList.append('<div>' + event.title + '</div>');
});
}
});
}
});
});
});ajax()Function to send HTTP request. First, when the page loads, we send a GET request to api/events to get the event list and render the list into the eventList container in the page. Then, when the form is submitted, we get the title and description from the input box and send it as data to a POST request to api/events to create a new event. After successful creation, we clear the form and reload the event list.
app.py, the code is as follows:
import webman
import sqlite3
app = webman.Application()
# 获取事件列表
@app.route('/api/events', methods=['GET'])
def get_events(request):
conn = sqlite3.connect('event.db')
cursor = conn.execute('SELECT * FROM event')
events = [{"id": row[0], "title": row[1], "description": row[2], "status": row[3]} for row in cursor]
conn.close()
return webman.Response.json(events)
# 创建事件
@app.route('/api/events', methods=['POST'])
def create_event(request):
data = request.json
title = data['title']
description = data['description']
status = '待处理'
conn = sqlite3.connect('event.db')
conn.execute('INSERT INTO event (title, description, status) VALUES (?, ?, ?)', (title, description, status))
conn.commit()
conn.close()
return webman.Response.empty()
# 运行应用程序
if __name__ == '__main__':
app.run()webman module, and then create A Application object named app. Next, we define a function for processing GET requests to obtain the event list, and use the json() function to convert the results into JSON format for return. Then, we define a function for handling POST requests to create a new event and store the data in the request body into the database. Finally, we use the run() function to run the application.
python app.py in the command line to start the application. Then, open the browser and visit http://localhost:8000/ to see our event management system interface. Event information can be submitted through the form and displayed in the event list in real time.
