I am trying to build a small database of Universities, Departments and Courses. But for some reason I can't seem to get a list of courses attached to a Department.
So far I have the following Database: => Course(id: integer, course_name: string, length: integer, description: text, programme: string, department_id: integer, university_id: integer, created_at: datetime, updated_at: datetime)
=> Department(id: integer, department_name: string, department_description: text, head_firstname: string, head_lastname: string, head_email: string, university_id: integer, courses_id: integer, created_at: datetime, updated_at: datetime)
=> University(id: integer, name: string, website: string, country: string, city: string, departments_id: integer, courses_id: integer, created_at: datetime, updated_at: datetime)
Models: class Course < ActiveRecord::Base belongs_to :department belongs_to :university end class Department < ActiveRecord::Base belongs_to :university has_many :courses end class University < ActiveRecord::Base has_many :departments has_many :courses end
For the Department I am trying to run the following controller def index @departments = Department.includes(:courses, :university)
and the following view: <% @departments.each do |department| %> <tr> <td><%= department.department_name %></td> <td><%= department.department_description %></td> <td><%= department.head_firstname %></td> <td><%= department.head_lastname %></td> <td><%= department.head_email %></td> <td><%= department.university.name %></td> <td><%= department.courses %>
that last line outputs #<Course:0x1042b8270> and it fails when i try to add something like department.courses.course_name
I am at a loss here and haven't been able to find any clues on the documentation as to what I might be doing wrong. If anyone could at least point me in the right direction, that would be great.
