has_and_belongs_to_many on legacy DB
...working with mapping ActiveRecord onto a legacy database. All is going
well (using set_table_name, set_primary_key, etc), but I can''t get my
many<=>many relationships to work.
My contrived example of the situation:
Student has_and_belongs_to_many Teachers. This is mapped via table
student2teacher where the foreign keys are studentId and teacherId. The
primary key in Student is studentId, and in Teacher is teacherId. However,
when I run my unit tests I am getting this error:
Mysql::Error: Unknown column ''j.student_id'' in ''where clause''
This is confusing,...
