The courseware_api view will use check_course_access - which now returns AccessResponse objects, and all other uses of check_course_access will now use check_course_access_with_redirect, which is a drop-in replacement for the original check_course_access implementation.
We also added a few new helpers to access_utils:
- check_public_access is a replacement for allow_public_access, which now returns AccessResponse objects
- check_enrollment checks if the learner is enrolled, and uses check_public_access to account for COURSE_ENABLE_UNENROLLED_ACCESS_FLAG
- check_survey checks whether there is a required survey that the learner must complete prior to accessing the course.
There are two new kinds of AccessError subclasses:
- SurveyRequiredAccessError
- EnrollmentRequiredAccessError
We weren’t using has_access to check user access, which meant we were missing out on a bunch of checks. This PR adds a local _check_access function to CoursewareInformation. Ideally we would add this into access.py, but we’re adding it here for now to avoid any unexpected regressions in editing more commonly used code. This should ultimately be folded into our access system properly.
