course_id

In this line of code:

step = get_object_or_404(Step, course_id=course_pk, pk=step_pk)

Is this course_id argument defined in Step module? Cause we know that get_object_or_404 function has know id about course_id!

When you call models.ForeignKey() in your 'Step' model, behind the scenes django appends '_id' to the fieldname ('course' in this instance), thereby creating its column name in the 'Step' table. Every row (instance) in your 'Step' table will have a value in the 'course_id' column which corresponds to the id of the course the step belongs to.
