Student ePub exports fail silently for concluded courses

Open christopher-b opened this issue 6 years ago • 5 comments

Summary:

On the ePub export page (https://your.canvas.com/epub_exports), concluded courses are listed, but trying to generate an export fails with no user feedback.

Steps to reproduce:

Enroll as a student in a concluded course
Try to generate an ePub export of that course.
Watch the JS console for an authorization error

Expected behavior:

Either the exported should be generated, or feedback should be provided to users stating that they cannot generate ePubs for concluded courses.

Actual behavior:

The export fails, with no feedback to the user.

Additional notes:

The problem lies here: https://github.com/instructure/canvas-lms/blob/e5b47766209cc534923ff67758d0350458997d6a/app/models/epub_export.rb#L85

Students cannot "participate" in concluded courses. I think this should be modified to allow students who can read the course to generate the export
