Follow the previous article to create an app named polls.

The file structure is as follows:

Then web2py automatically adds some code to it.

We need to remove some, such as the controllers and defualt. py index methods;

Corresponding to default/index.html under the views folder

In fact, it is not difficult to see the ing between the controller and views of web2py.

Files under controller correspond to a folder under view (controllers/default. py corresponds to views/default/folder ),

Then we will remove some irrelevant content from the c and v of the corresponding relationship.

As follows:
