…org_for_user RoleBase._authz_get_orgs_for_user() read assignment.scope.org for every AuthZ assignment, but PlatformGlobData (course-v1:*, lib:*) has no .org attribute at all, unlike CourseOverviewData/OrgGlobData where it's a real (possibly None) field. Any user with a platform-wide role crashed get_orgs_for_user()/has_org_for_user() with an AttributeError. Special-case platform-wide assignments: since they cover every org, return all registered org short names instead of deriving them from individual assignments. Fixes openedx/openedx-authz#380

And could we please update test_course_listing.py module to use the build_external_key method? I forgot to do that in some of the tests.

Applied — wrapped it in PlatformCourseOverviewGlobData(...) since the literal suggestion would assign a bare string to scope (RoleAssignmentData.scope expects a ScopeData instance). Also updated test_course_listing.py's platform/org-glob tests to use build_external_key() as you asked. Fixed in d32aa52.

Yes, you're right. Now that I'm taking a closer look at the test, instead of mocking the assignments, could we use the assign_role_to_user_in_scope function? Something like this:
assign_role_to_user_in_scope(
self.student.username,
COURSE_STAFF.external_key,
PlatformCourseOverviewGlobData.build_external_key(),

Good idea — this is actually stronger, since it exercises the real Casbin assignment + policy load instead of mocking get_user_role_assignments_filtered. It also caught a latent bug in my mock: I had RoleData(external_key=COURSE_STAFF) (the RoleData object itself) instead of COURSE_STAFF.external_key, which the mock silently tolerated since it bypassed the real filtering. Switched to assign_role_to_user_in_scope + load_policy() in 795de56.
Per review feedback from @BryanttV on openedx#38980, also applied to test_course_listing.py which had the same pattern in unrelated pre-existing tests.

…ents Per review feedback from @BryanttV on openedx#38980: exercising the real Casbin policy assignment + get_orgs_for_user path is more faithful than mocking get_user_role_assignments_filtered directly, and it catches issues the mock papered over (the mocked RoleData had external_key=COURSE_STAFF, the RoleData object itself, instead of COURSE_STAFF.external_key).

Sorry for being late to this review. Does this return the same structure as in L641? Can we make sure of this with a test - like a test case that for a user returns a subset and for another all orgs? Not sure if we're doing that already. Thanks

No worries about the timing! Yes — both branches return the same shape, a plain list[str] of org short names (L640 is a list comprehension over get_organizations(), L641 is list(a set) of assignment.scope.org values). Added test_get_orgs_for_user_authz_platform_glob_vs_org_scoped: it registers a third org that's never assigned to anyone, then asserts an org-scoped grant returns only its own org while a platform-wide grant returns all three, against that same shared pool of orgs — so the two branches are actually distinguished instead of just coincidentally returning the same numbers (which is what my original platform_glob test alone couldn't rule out, since it only ever registered exactly the orgs it expected back). Verified locally against a real devstack. Fixed in fbb2726.
Per review feedback from @mariajgrimaldi on openedx#38980: registers a third org that's never assigned, then asserts an org-scoped grant returns only its own org while a platform-wide grant returns all three, against the same pool of registered orgs — so the two branches (roles.py L640 vs L641, both list[str]) are actually distinguished by the test instead of coincidentally matching.
Description
Fixes openedx-authz#380
RoleBase._authz_get_orgs_for_user()(common/djangoapps/student/roles.py) readsassignment.scope.orgfor every AuthZ assignment. However,PlatformGlobData(thecourse-v1:*/lib:*platform-wide scopes) does not have an.orgattribute, unlikeCourseOverviewData/OrgGlobData, where.orgis a valid (possiblyNone) field.As a result, any user with a role assigned at a platform-wide scope would cause
get_orgs_for_user()/has_org_for_user()to fail with anAttributeError.The fix handles platform-wide assignments before accessing
.org. Since a platform-wide grant applies to every organization, the compatibility layer returns all registered organization short names instead of trying to derive them from individual assignments.Testing Instructions
authz.enable_course_authoringflag globally.course-v1:*).role.get_orgs_for_user(user)/role.has_org_for_user(user), or trigger any code path that uses them (e.g., the Studio course listing).AttributeErroris raised.Added
test_get_orgs_for_user_authz_platform_globincommon/djangoapps/student/tests/test_roles.pyto cover this case.
