Comment (by ontowhee):

 Replying to [comment:10 David Sanders]:

 Thanks for the simple example!

 I'm not too knowledgeable about the ORM, but I'm trying to work through
 this problem. Is the problem within annotate, or somewhere else, or a
 combination of annotate and something else?

 Using the simple example, I tried taking the union of Foo and Bar without
 any annotation, and I apply `.values('name')` to the result


 {{{
 Foo.objects.create(name='hello')
 Bar.objects.create(name='goodbye')

 qs = Foo.objects.all().union(Bar.objects.all())
 print(qs)
 }}}

 and it gives

 {{{
 
 }}}

 Which is correct and expected. However, when I remove `.values('name')`

 {{{
 qs = Foo.objects.all().union(Bar.objects.all())
 print(qs)
 }}}

 it then gives

 {{{
 , ]>
 }}}

 Is this expected, or is this something to look into?

Comment:

 If it helps, while checking if #34945 was a duplicate of this I was able
 to boil down the failure to this simple example:

 {{{
 class Foo(Model):
 name = CharField()

 class Bar(Model):
 name = CharField()

 qs = (
 Foo.objects.annotate(alias=F("name"))
 .union(Bar.objects.annotate(alias=F("name")))
 .values("alias")
 )
 print(qs)
 }}}

 gives

 {{{
 
 }}}
