Hi @Zerotask

I"m not sure about this part

@api.api_operation([HTTPMethod.POST, HTTPMethod.PATCH], "/path")

this makes it longer, and it is not really a place which people use often or make mistakes...
but redabitliy of the code is degrading...

Hi @Zerotask

@api.api_operation([HTTPMethod.POST, HTTPMethod.PATCH], "/path")

My intention was to provide a default way which supports auto completion and ensures it's written correctly. For example, some people could accidentally write OPTION instead of OPTIONS or they have to lookup all available HTTP methods on the web.
Personally I also prefer enums over raw strings.

I changed it back.
