This also has an initial use case for Personalized Learner Schedules
to add CTAs to capa and vertical blocks to allow users to shift their
course deadlines.
These are expensive, read-only web requests. Unfortunately,
middleware adds writes, and we currently run with view-level
transactions enabled by default. Holding those long transactions
open has caused extra load on the database and been our largest
sources of django.db.utils:OperationError exceptions.
This has been particularly noticeable as we start deploying the
new Courseware MFE, which uses the BlocksInCourseView more
frequently.
This switches the Dates Tab to be an enrolled tab allowing only
enrolled learners to view. Additionally, it will now redirect
logged out learners to the login page if they hit the Dates Tab directly.
- use new dates banner template on course outline page
- remove old banner from main.html
- let dates tab use new dates banner template
- remove dates banner completely from the courseware problem view
on the web app
- use new banner on the courseware problem view on the mobile app
- update banner util to use get_course_blocks

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
- remove code for displaying banner in mobile dates fragment
- replace button with link to web app in reset dates banner on
the mobile problem template
- adjust spacing of reset dates button in banner when button wraps
on smaller screen
- for self paced courses, if a sequential's due date has passed
and it is incomplete, allow the user to reset the start_date
for the related schedule to now, thus shifting all due dates
for all sequentials within the course by the pre determined
due date offset.
- add historical table to the Schedule model.
