[ckan-dev] Overriding controllers in plugins?

Wed Aug 5 16:21:37 UTC 2015

Is it possible to override a stock CKAN controller in a plugin?  I am attempting to load a new controller for controllers.user.read.  I want to restrict access so only users themselves can see their own profiles.

I tried to use the before_map class from IRoutes like this, so that my custom read controller would be called:
            m.connect('user_datasets', '/user/{id:.*}', action='mngeo_user_read', ckan_icon='sitemap')

I was hoping this would override this mapping from config.routing:
        m.connect('user_datasets', '/user/{id:.*}', action='read',
                  ckan_icon='sitemap')

The trouble I am having seems to be that since this is being implemented _before_ the routes in config.routing, it is "greedy" and is catching requests to pages such as user/login

Using the after_map would seem to implement my class too late.

I also tried to not use any IRoutes and just have my replacement controller named "read" hoping it would take the place of the main ckan controller.

Can anyone explain how I can get my own controller to get mapped?  Or if I appear to be just generally confused, set me on the right path?

Many thanks,
