Adding a new tab in Profile (n00b)

[Kimball]

I'm trying to learn Ruby, Rails and Insoshi all at the same time.
I've created a migration for a new entity, Entity (belongs_to :person)
to be associated with Person (has_many :entities) and I can do CRUD on
the Entity model. I'm using Galleries as a metaphor, and I'm getting
an error creating the tabs:

The @people variable appears to be empty. Did you forget to pass the
collection object for will_paginate?

I can't seem to find any documentation about Insoshi itself, is there
somewhere I should be looking? I suspect I need to modify routes.rb
maybe or edit the view code?

I'll be putting this app into production as soon as I feel comfortable
with everything.

Many thanks,
