What does this mean -uninitialized constant ActionView Base

Full error: uninitialized constant ActionView Base::CompiledTemplates

Not sure here. I have a controller, model and views for something
called
‘cana’,
Howere I also have a model and a table called ‘canb’.

In the show template for ‘cana’ I’m attempting to do:

<% @canbs = Canb.find(:all) %>
<% for canb in @canbs %>

Actually the names are different and longer but for this email I’ve
chosing
cana and canb.

So am I getting this error because canb needs it’s own view , controller
or
both ?
