The following modifications were made:

1. Copied in some code from the previous semester's implementation of this project (https://github.com/expertiza/expertiza/pull/1270/commits/72d97ffb5dd2279202efb2b1d329d64618403725 - they didn't do it properly and weren't permitted to check-in)

2. Successfully recreated Expertiza issue #98

3. When checking whether a team needs to be removed from the waitlist, looped through all waitlisted teams on all topics for which the drop topic deadline has passed

4. Renamed the update_is_waitlisted method to clear_waitlisted_teams_for_topic to better reflect what the method does

5. Moved the code to clear the waitlists if needed to within sign_up_topic.rb so it can be called from multiple locations

6. Added call to clear the waitlists if needed to assignments_controller - edit and update, so the instructor can also see the updated state with the cleared waitlists

7. Verified Expertiza issue #98 has been fixed

8. Tested to ensure things work if it’s a staggered deadline assignment

9. Updated documentation on wiki




Unable to complete:

1. Remove commit fb75d88e5519e56003eaaa56e01173c0479d2682 from our branch

2. Adding field auto_dropped_from_waitlist to SignedUpTeam

3. Rather than deleting a waitlisted team from the topic altogether, unmark "is_waitlisted" and instead mark "auto_dropped_from_waitlist" to preserve the history

4. Adding the "auto_dropped_from_waitlist" to a view so the instructor could see it

5. Fix Expertiza issue #154

Other related issues found:

- When editing an assignment's due dates, the drop topic deadline won't display unless the signup deadline is displayed

- When a student is on the waitlist for more than one topic, only the row for one of the topics is grey

- There seems to be about a 20 minute drop topic deadline lag, some of the time

- Click on the assignment you just created

- Click "Signup sheet"

- Click the green checkmark under "Actions"

- (Repeat the above steps until there are enough students to have one on the waitlist)

   Uncheck "Use drop topic deadline"

- Click "Impersonate User"

- Enter a student's username who has signed up for a topic of this assignment

- Click on the assignment you just created

- Click "Signup sheet"

- Notice how the student has the option to drop this topic

- Also notice there is a student on the waitlist

- Allow the drop topic deadline you set to pass

- Refresh the page

- Notice now the student does not have the option to drop this topic

   This is working as desired

- Also notice there is still a student on the waitlist

   This is Expertiza issue #98
   The waitlist should be cleared when a drop topic deadline has passed
