SDS Laravel: Fixes to Broken Behavior
2024 Apr 18: User Preferences Screen Fails to Display
Context: User darren.duncan attempted to visit their
User Preferences screen, example urls
https://api.smus.ca/User/Preferences (production) and
https://api-latest.smus.ca/User/Preferences (preview).
Observed Behavior: In production, a non-graceful generic 500
internal server error message was displayed rather than the expected
User Preferences screen. In preview, the revealed underlying symptom was
that the code line in PreferencesController of
$addresses = $user->guardian->addresses; was dying with
Attempt to read property addresses on null. The problem
occurred for user darren.duncan but not for other users.
Expected Behavior: The User Preferences screen should always display, regardless of whether the user in question is a guardian or has guardians. If some functionality of the screen is not applicable for users that aren't or don't have guardians, the screen should either hide that functionality or explain why it doesn't apply or both.
Applied Solution: The dying code line was replaced with code that only tried to fetch and return an address list when it was valid to do so, and it returned an empty list otherwise. As a result, the User Preferences screen never failed to display under this scenario.
Caveat: While the User Preferences screen no longer fails to
display, as of the completion of this fix, it still remained true that
the functionality to actually display the fetched address list in
question was never implemented, and so for every user, the screen
carried the placeholder message Shows address info instead
of each individual address.
