Thanks Colin..
I am using ternary operator on @currentuser:
@currentuser ? can_admin?(topic) : false .
User model method: topic_admin changed to can_create
Topic model method: can_admin changed to can_be_created_by
@currentuser.can_create?(topic)
### User model has this method:
def can_create?(topic)
topic.can_be_created_by?(self)
end
----
### Topic model has this method:
def can_be_created_by?(user)
valid_roles = %w{admin editor}
if valid_roles.include?(user.role.name)
return true
else
return false
end
end

Problem -
I have nested resources in my application - (topic has_many items). And
on my show topic page I have a link to 'Add new item'. I would like to
show this link only to users with certain roles. However, I am not able
to pass this resource (item) as it has not been initialized. So how can
I call method like: @currentuser.can_create?(item) from my show topic
page. I am initializing resource objects within the controller, but how
can I initialize these from my view? Do I need to? Any clues?
