progress pages are broken

[anandology]

We have progress pages on mon school at /mon/progress and /mon/student_progress.

Traceback

Notes

Looks like this is failing now.

    def get_lessons(self):
        return [lesson
                for c in self.course.get_chapters()
                for lesson in c.get_lessons()]

@pateljannat looks like your recent refactoring of lessons and chapters broke this.

@anandology

In progress.py if you replace the line

self.lessons = self.get_lessons()

with

self.lessons = self.course.get_lessons()

the issue would be resolved. You won't need the get_lessons function of progress.py then.

Let me know if this works

Thanks @pateljannat. That fixed the issue.
