29142	QuerySet crashes when OuterRef is combined with an operator	Michael Barr	Matthew Schinckel	"[https://docs.djangoproject.com/en/2.0/ref/models/expressions/#referencing-columns-from-the-outer-queryset According to the documentation on models.OuterRef]:

""It acts like an F expression except that the check to see if it refers to a valid field isn’t made until the outer queryset is resolved.""

I am experiencing an issue with this using the following example:

{{{
class ExampleModel(models.Model):
    date = models.DateField()
    value = models.IntegerField()


subquery = ExampleModel.objects.filter(
    date__gte=models.OuterRef('date') - timedelta(days=2),
    date__lte=models.OuterRef('date') + timedelta(days=2),
    value__lte=5
)
queryset = ExampleModel.objects.annotate(
    value_is_lte_five=models.Exists(subquery)
)
}}}

 
The result that I am getting is:

AttributeError: 'ResolvedOuterRef' object has no attribute 'relabeled_clone'

From my understanding, if this is similar to an F Expression, you should be able to perform the timedelta on the OuterRef. [https://stackoverflow.com/questions/48230771/is-it-possible-to-do-arithmetic-operation-on-outerref-expression I also found someone else on StackOverflow with the same issue]. 

What I would like to know is if this is a bug (e.g. should it be supported), or a documentation issue. "	Bug	closed	Database layer (models, ORM)	2.0	Normal	fixed		Matthew Schinckel	Ready for checkin	0	0	0	0	0	0
