I have two classes: {{{ class DashboardSuggestion(BaseModel): active = models.BooleanField(default=True) title = models.CharField(max_length=50) body = models.CharField(max_length=80) max_dismissals = models.IntegerField(default=1) days_between_dismissals = models.IntegerField(null=True, blank=True) objects = DashboardSuggestionQuerySet.as_manager() class Meta: db_table = 'dashboard_suggestion' }}} {{{ class DashboardSuggestionDismiss(BaseModel): suggestion = models.ForeignKey('suggestions.DashboardSuggestion', on_delete=models.CASCADE, related_name='dismissals') user = models.ForeignKey('users.User', on_delete=models.SET_NULL, null=True, blank=True) company = models.ForeignKey('companies.Company', on_delete=models.SET_NULL, null=True, blank=True) count = models.IntegerField(default=1) class Meta: db_table = 'dashboard_suggestion_dismiss' unique_together = ['user', 'suggestion', 'company'] }}} And the following QuerySet: {{{ class DashboardSuggestionQuerySet(models.QuerySet): def for_dashboard(self, user, company): queryset = self.annotate( is_dismissed=FilteredRelation( 'dismissals', condition=( Q(dismissals__user=user) & Q(dismissals__company=company) & ( Q(dismissals__count__gte=F('max_dismissals')) | Q(dismissals__updated__gt=timezone.now() - timezone.timedelta(days=1) * F('days_between_dismissals')) ) ) ), ).filter( Q(is_dismissed__isnull=True), ) }}} When I attempt to call `DashboardSuggestion.objects.for_dashboard(user, company)` I receive the following error: `Cannot resolve keyword 'days_between_is_dismissed' into field. Choices are...` The string `days_between_is_dismissed` does not exist anywhere in my code. I do not see where it is being used or generated at all. Trying to do a bit of debugging, somehow the `F('days_between_dismissals')` in the FilteredRelation condition is getting converted to `F(days_between_is_dismissed)` but I have not yet found the exact place that is happening. This code was working as I expected in Django 4.2. -- Ticket URL: <https://code.djangoproject.com/ticket/35050> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
