ActionView::Template::Error

I am trying to call the user_id and role_id field from a hash current_role. When I try calling current_role.role_id or current_role.user_id, I get the following error message:

ActionView::Template::Error (undefined method `role_id' for #<ActiveRecord::Relation::ActiveRecord_Relation_RoleMembership:0x00000103d4fbd0>):

If I try to run current_role.inspect, I see that both user_id and role_id are both set. Here is the response from current_role.inspect:

#<ActiveRecord::Relation [#<RoleMembership id: 1, user_id: 1, role_id: 2, created_at: "2014-01-27 02:25:25", updated_at: "2014-01-27 02:25:25">]>

Why am I unable to call current_role.role_id or current_role.user_id? Any help would be appreciated.

That's because current_role is an instance of ActiveRecord::Relation and not RoleMembership.

To get the role_id of the first RoleMembership in the current_role relation, use: 

current_role.first.role_id

If you want to make current_role default to the first RoleMembership, you should update your current_role definition to something like follows: 

def current_role
  RoleMembership.where(...).first
end

With the updated current_role definition, you will then be able to use current_role.role_id and it will return the expected role_id.
