Can Django ORM's `.first` return `None` for a non-empty queryset?
I have a very simple model called Achievement. In an algorithm, I reach a point in which I have a queryset for this model - named achievements bellow. I got in a situation in which the method .first() applied to this queryset outputs None, even though there is an element in the queryset. In summary, achievements.order_by('-amount')[0] # outputs an achievement achievements.order_by('-amount').first() # None achievements.count() # 1 How can this happen? There is no default ordering for this model. -

How to annotate Django Queryset with the same value but with a different data type of one of existing fields?
I have a Django model that has a NumberVal field which is models.FloatField(). Then I need to annotate the queryset objects like so .annotate(numberval_as_text=str(OuterRef("NumberVal"))) - the same value, but as a string except for the fact that this throws QuerySet.annotate() received non-expression(s): OuterRef(NumberVal) error which is clearly right but it demonstrates the point. I need this because this annotation is followed by an extensive second annotation where I need this numberval_as_text in subquery filters. Any hint would be appreciated. -
