Re: CrudRestController and @before_validate

I have now just set the mount_point to . and it seems to work, the pager links are correct now and I haven't noticed any other breakage...

@cached_property

def mount_point(self):

return '.'

And in response to your question from irc (sorry, wasn't at home yesterday), yes, I need to give the sub-controllers the id of the parent object.

So that I get urls like

/events/eip12/lessons/1/teams/

And the lesson_id=1 is specific to the event "eip12".

Probably like Github urls where the issue ids are unique just for the repo they belong to.

I thought that would have to be done using _lookup for the nested controllers, or is there another way that I have overseen?

Thanks,

Moritz

mount_point would return None for a non statically mounted controller,
so it won't probably solve the issue.

If the issue is caused by the fact that you need to allocate the
controllers with some options you can use cached_property to make it
behave as it was statically mounted. Take a look at
https://bitbucket.org/_amol_/tgapp-photos/src/81288e064f75/photos/controllers/root.py
to see what I mean.

If you really need to serve the controllers from _lookup you must
override _mount_point to use request.path_info
Something like request.path_info[len(tg.dispatched_controller().mount_point):].split('/')[0]
might be the way to go, but I don't have any ready made snippet for
something like that as I always served crud rest controllers from
statically mounted places or cached properties.
