multiple controllers with one view

[lbjc...@gmail.com]

I have two controllers in an app. 

One controller has functions that manage DAL tables and forms. The second has imported module that are sometimes called. They both use one view. I have tried to figure out ho to work this out but cant find ho to print results to view from the second controller. With this arrangement, I keep getting an error message:  

name 'conversations' is not defined

. My second controller has this code:

def conversations():
    row = db(db.post.author== auth.user.id).select(db.post.id, db.post.convo, orderby=~db.post.id, limitby=(0,1)).first()
    id = row.convo if row else None
    return dict(id=id)


with the view.html
{{=conversations()}}

I tried looking for an example, reference previous items related to this and the only answer I got online is this

The error is shown because you only send a variable 'id' to the view. All variables used in the view should be send in the dict you return from the controller. Please check the web2py book on the website on views and controllers.

To choose which view, put 

response.view="view.html"

in the 2 controllers that share the same view.

And you need to return the same variables used for the view in both controllers.

def conversations():
    row = db(db.post.author== auth.user.id).select(db.post.id, db.post.convo, orderby=~db.post.id, limitby=(0,1)).first()
    id = row.convo if row else None
    return dict(id=id)


with the view.html
{{=conversations()}}

You must either include "conversations" as a key in the dict returned by the controller (so it will be available as a variable in the view), or check for the existence of "conversations" in the view before attempting to access it:

{{if 'conversations' in globals():}}
{{=conversations()}}
{{pass}}
