That way, your application won't have to generate the schema every time a user opens your API docs.

It will be generated only once, and then the same cached schema will be used for the next requests.

### Override the method

Now you can replace the `.openapi()` method with your new function.

Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded`.

But when the form includes files, it is encoded as `multipart/form-data`. You'll read about handling files in the next chapter.

  `Never mind!' said the King, with an air of great relief.
`Call the next witness.'  And he added in an undertone to the
Queen, `Really, my dear, YOU must cross-examine the next witness.
It quite makes my forehead ache!'

  Alice watched the White Rabbit as he fumbled over the list,
feeling very curious to see what the next witness would be like,
`--for they haven't got much evidence YET,' she said to herself.
