Re: [web2py] Re: web2py reports "invalid function (client/get_approval)" when function has typing return type

[João Matos]

Hello, I already opened an issue on Github. Thanks, but I prefer to stick with the old type syntax # type: () -> Dict[str, SQLFORM] solution instead of creating another function. Best regards, João Matos On 08-03-2019 16:45, Anthony wrote: In order to determine which functions in a controller file to expose as actions, web2py uses the following regex (the intention is to identify only functions that take no arguments and don't start with a double underscore): '^def\s+(?P<name>_?[a-zA-Z0-9]\w*)\( *\)\s*:' As you can see, this does not support type hints. Feel free to open an issue on Github or submit a pull request to allow type hints. In the meantime, you can create a separate function with the type hint and call that function from within a non-hinted action: def get_approval():     return hinted_get_approval() Anthony On Friday, March 8, 2019 at 9:31:58 AM UTC-5, João Matos wrote: If I write this function from typing import Dict @auth.requires(lambda: (auth.requires_login() and request.env.http_referer and ('/client' in request.env.http_referer or '/client/get_approval' in request.env.http_referer))) def get_approval() -> Dict[str, SQLFORM]: """Get approval for deletion. :return: Dict with form.

I even tried with just -> Dict to see if it was a problem with SQLFORM, but it returns the same message.
