Hey everyone,
I have a project relating courses and professors. Each course can have multiple professors and each professor can have multiple courses, so I have a many-many table, professors_courses with a PRIMARY key defined on professor_id, course_id.
This table also contains some metadata about the professor/course combination. So, as a result, I have a model for that many-many relationship, ProfessorCourse.
I am trying to do this:
ProfessorCourse::model()->with( 'professor', 'course' )->findByPk( array( 'course_id' => 5, 'professor_id' => 10 ) );
Where my relations are defined as:
return array(
'course' => array( self::HAS_ONE, 'Course', 'course_id' ),
'professor' => array( self::HAS_ONE, 'Professor', 'professor_id' )
);
However, because of the composite key on ProfessorCourse in my many-many model, it is attempting to join courses ON (course.course_id = t.professor_id) (notice it is matching the course ID based on the combo’s professor ID)
Is there any way to specify which primary key in the many-many table to use on the JOIN for my relation? Does anyone have other suggestion on how to accomplish this task with models?
