i have two models. Teacher and Subject joined by HABTM defined both ways. A teacher can teach many subjects and a subject can be taught by many teachers.my join table is subjects_teachers and have fields id,teacher_id and subject_id.
Fetching Teacher data from its model, i expect all teachers and their respective subjects , Fetching Subject data from its model i expect to also see the teachers teaching that particular subject
problem on both instances, the associated model returns the correct number of records but the data is absent. i see [maximum depth reached] when i display the respective arrays.
I removed the id field from the join table and that fixed only the Teacher model.The Subject model still has the problem.
i just need to know what [maximum depth reached] means and why removing the id filed from the join table fixed the Teacher problem but not Subject.
also if its important i should mention that my Teacher model primary key field doesnt follow convention SUBJECT model
