Subject: Stupid TypeError while checking array values

Not sure if I'm even close to the mark on this.  Ruby noob here...RACKIN 
M'BRAINS HERE!! :(

I am trying to check values of an array against another value. 
Unfortunately, I keep getting a TypeError that says:

can't convert User into Integer

I am trying to check if a logged in user has access to a course id based 
on ownership assignments.

I have 2 tables having M:M relationship and a join table:

****************
*              *
*   Courses    *
*              *
****************

**********************
*                    *
*   Courses_Users    *
*                    *
**********************

****************
*              *
*    Users     *
*              *
****************

...and here is my action

  def user_assigned_course(course_id, user_id)
    allowed_users = Course.find_by_id(course_id).users
    allowed_users.each do |user|
      if allowed_users[user] == user_id
        return true
      end
    end
  end

...help...
