Question

In my html.erb views I can normally use code like:

if current_user.role?(:label)
"do something"
end

I’m trying to do the same in a Prawn based PDF but am getting a “undefined local variable or method `current_user'” error.

I understand I need to explicitly include a helper in my PDF class, something like:

class SalesnotePdf < Prawn::Document
  include CanCan::Ability
  "do pdf layout here"
end

But this doesn’t appear to work? Any ideas on the correct include or other approach to this?

Thanks in advance!

EDIT:
I think current_user is actually a Devise method I need to access.

Answer 1

Well, current_user really is a Devise method and is available in views, helpers and controllers, but not models. A better approach would be to check the user’s role in a controller and then call a specific Prawn document.
