I upgraded py4web today from a version that was several months old. Now I'm getting this error:
-------------------------------------
ombott.router.errors.RouteMethodError: Handler is already registred for `['GET', 'DELETE', 'HEAD', 'POST', 'PUT']`
-------------------------------------

I think this is related to @action decorators, but I'm not sure exactly what I need to change.

I have a lines like this for each of my page defs:
-------------------------------------
@action('outdoor_table', method=['POST', 'GET'])
@action('outdoor_table/<path:path>', method=['POST', 'GET'])
--------------------------------------

 Can somebody give me a suggestion on this?

Hi!
This error occurs when trying to overwrite already registered routes (or rather, registered method(s) of routes). If you really want to do that, add overwrite=True:

@action('some/route/to/overwrite',  method=[...],  overwrite=True)

just in case  - this should work (it does not require overwrite=True) :
@action('outdoor_table', method=['POST', 'GET'])
@action('outdoor_table/<path:path>', method=['POST', 'GET'])

I had a decorator like this

@unauthenticated("index", "index.html")

I thought that this was used to redirect unauthenticated users to a different page (although I can't find this documented). This seems to be the cause of the problems I was seeing. For some reason, it didn't cause a problem in the previous version of py4web, but did cause a problem in the updated version. I've removed this line and that seems to have fixed the problem. Is the syntax of this code correct?

Syntax is correct, but this decorator cannot be combined with @action/@action.uses

OK, I see that I was using @unauthenticated inappropriately. It's curious, though, that it didn't seem to break when used that way in the previous version of py4web, but did cause a problem with the latest source.  Maybe the switch to ombott changed the way it behaved.

Also, I don't see any documentation showing use of  @unauthenticated with parameters like this:  @unauthenticated("index", "index.html"). That would be a good thing to add. Is there a good way to redirect unauthenticated users without using @unauthenticated?

ombott does not allow to overwrite routes randomly (which is good I think), but  bottle does.

Strongly agree. Ombott does it better
