Examples of views and templates
The
logic of building a simple jump interface is as follows: The
detailed description is as follows:
1. The interface index.html is inherited from base.html
2. The function of base.html is completed by the macro macroobject.html
3. Click the link in index.html and jump through the route. Transfer, and grab the URL key field from request.args.get, to judge in the view, and return the judged content to detial.html
