Org: Replace assert current_user is not None with a Sentry warning and HTTPForbidden

Adds OrgRequest.get_current_user() which captures a Sentry warning and raises HTTPForbidden when current_user is None despite a valid session. Replaces all bare asserts across feriennet, org, town6 and translator_directory.

Copilot

Pull request overview

This PR aims to prevent crashes when request.current_user is unexpectedly None by introducing a safer accessor on OrgRequest and replacing a number of assert request.current_user is not None call sites with either request.get_current_user() or guard clauses.

Changes:

Added OrgRequest.get_current_user() which raises HTTPForbidden and attempts to emit a Sentry warning when current_user is unexpectedly missing.
Replaced multiple assert request.current_user is not None usages with request.get_current_user() across org/feriennet/translator_directory views and helpers.
Added unit tests for the new get_current_user() behavior.

@Daverball Is this a good approach to prevent assertion errors at runtime but try to identify the root cause of current_user beeing None?

…user NO_IDENTITY is not None, so the previous guard would trigger a spurious Sentry warning for unauthenticated requests. Use is_logged_in instead, which correctly checks identity is not NO_IDENTITY. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

MagicMock auto-creates truthy attributes, so setting identity=None had no effect on the is_logged_in check. Explicitly set is_logged_in=True/False to reflect the actual condition the code under test checks. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

The method raises HTTPForbidden for any None current_user, not just the stale-session case. Clarify that anonymous requests are also forbidden, and that Sentry is only notified for the logged-in-but-missing-user case. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Daverball · 2026-05-08T16:45:51Z

The root cause of this exception is most likely that changing a translator's e-mail address does not log them out. So they're still logged in with their old e-mail, which no longer has an associated account, so get_current_user will return None.

So I don't think we should make any large sweeping changes to make the application not crash, when this happens. Since after all it is a real problem if we didn't log that user out.

It might be worth adding a change_username method to User which calls self.logout_all_sessions() and then switch to using that instead of manually updating User.username, everywhere it is relevant, so we can't forget to do this step.

Although we probably could change current_user to use the primary key instead of the username in order to retrieve the User object, since we now store both in the identity object and the primary key will never change. But we would still need to detect when the username in the identity no longer matches the username of the User and update the cached username in the session, since otherwise there may still be some odd behavior for code that relies on request.current_username.

Is that related to LDAP?

Daverball · 2026-05-22T14:31:19Z

Is that related to LDAP?

It shouldn't be an issue during external login, although I'm not sure what happens if they have multiple sessions and their LDAP username gets changed during external login, I'm not sure if we remembered to terminate all the other sessions, so only the one with the new name remains.

But with translators it's also possible for admins to change the name of the translator, which gets mirrored back to the user if I'm not mistaken and we could be forgetting to log the user out there as well. There's also the LDAP synchronization cronjob, although I'm not sure if we have that for translator directory or if it's only running for FSI.

Either way there are quite a few ways the username can change, and we probably didn't remember to log out the active session for some of the ways. That's why adding a change_username method makes sense to me, so it's not as easy to forget. Either way you will have to look at all of the places in the code that update the username and check if they also call logout_all_sessions() and either add the missing call or refactor to change_username().
