How to write custom menu functions for CMS systems in Python

How to write the custom menu function of the CMS system in Python
When developing and designing a CMS (content management system), the custom menu function is a very important part. It allows users to customize the menu according to their needs and preferences for quick access to various features and pages. In this article, we will write a simple CMS system using Python and add custom menu functionality.

First, we need to create a menu class to store and manage menu item information. Each menu item contains a name and corresponding page path. We can use a dictionary to represent a collection of menu items, where the key is the menu name and the value is the page path. Here is the sample code for the menu class:

class Menu:
    def __init__(self):
        self.menu_items = {}
        
    def add_menu_item(self, name, path):
        self.menu_items[name] = path
        
    def remove_menu_item(self, name):
        if name in self.menu_items:
            del self.menu_items[name]
        
    def get_menu_items(self):
        return self.menu_items

Next, we need to write a function to display the menu. This function will perform the corresponding operation based on the user's selection. Here is a simple sample code:

def show_menu(menu):
    print("===== 自定义菜单 =====")
    menu_items = menu.get_menu_items()
    
    for index, (name, path) in enumerate(menu_items.items(), start=1):
        print(f"{index}. {name}")
        
    print("====================")
    
    choice = int(input("请选择一个菜单项: "))
    
    if 1 <= choice <= len(menu_items):
        selected_menu_item = list(menu_items.keys())[choice - 1]
        print(f"你选择了菜单项 '{selected_menu_item}'，页面路径为 '{menu_items[selected_menu_item]}'")
    else:
        print("无效的选择！")

Now, we can use this code in the main program to create a CMS system and add custom menu functionality. The following is a sample code:

def main():
    menu = Menu()
    
    menu.add_menu_item("首页", "/")
    menu.add_menu_item("文章列表", "/articles")
    menu.add_menu_item("用户管理", "/users")
    
    show_menu(menu)

if __name__ == "__main__":
    main()

In this example, we first create a Menu object and add three menu items using the add_menu_item() method. Then, we call the show_menu() function to display the menu and perform the corresponding actions based on the user selection.

This is just a simple example, you can extend and modify the code according to your actual needs. For example, you can add more menu items, improve the style of menu display, perform additional actions when selecting menu items, and more.

To summarize, we wrote a simple CMS system using Python and added custom menu functions. Through this example, you can learn how to use object-oriented programming and basic user interaction to implement this functionality. I wish you success in developing a CMS system!
