Is $result always going to be an <expression> at this point, and never an <operator-expression> as it expected by $not?

This is related to my other comment, in that I'm curious how this wasn't discovered sooner unless it was only recently introduced. This also hints at a gap in functional test coverage running generated queries on a live server.

Yes, compileWhere* function always return expressions with $and, $or or a field name, and now $nor.

if (str_ends_with($where['boolean'], 'not')) {
$result = ['$not' => $result];
$result = ['$nor' => [$result]];

I don't see PHPORM-90 linked to anything. This this bug predate us taking over the library, or was it introduced during some recent query refactoring? If the latter, we should link it up.

I implemented whereNot in GromNaN/laravel-mongodb#13. The issue PHPORM-49 is now linked in Jira.

This test is failing if I run it on version 3.9.3: the generated query was { title: 'admin' }, which is wrong because it ignore the negation.
In the current master, the query is { $not: { title: 'admin' } }, which is invalid and rejected by the server.
With this patch, the working query is { $nor: [ { title: 'admin' } ] }.

reviewing the generated query was { title: 'admin' }, which is wrong because it ignore the negation.

I'm not sure if I realized this when originally reviewing PHPORM-49, but the fact that earlier versions completely ignored negations with no feedback to the user sounds like pretty disastrous bug.

It looks like someone asked for this feature: #2418
