Help in error

[koren85]

I get Error when I use this code in before_save:

c_role_ids = User.current.membership(self.tracker_id).try(:role_ids) || []
  u=User.find(self.assigned_to)
  a_role_ids = u.membership(self.tracker_id).try(:role_ids) || []
  if c_role_ids.include? 6
    if a_role_ids.include? 3 
      raise WorkflowError.new("Error")
    end
  end

Eror then I save rule:

undefined method `membership' for nil:NilClass``

but in ruby console I get rusult

irb(main):018:0> a_role_ids = u.membership(30).try(:role_ids) || []
=> [9, 3, 13, 19, 15]

What I do wrong?

Hi,

You get an error, because you're using an assigned user for membership and the interpreter also thinks of the possibility of what happens if the assigned user is not specified. In this case, you want to get membership for nil.

Try this code, it should work:

if self.assigned_to
   c_role_ids = User.current.membership(self.tracker_id).try(:role_ids) || []
   u=User.find(self.assigned_to)
   a_role_ids = u.membership(self.tracker_id).try(:role_ids) || []

      if c_role_ids.include? 6
         if a_role_ids.include? 3 
            raise WorkflowError.new("Error")
         end
     end
end

I hope its help!
