Is there a possibility to do a pagination with union types?
My implementation currently looks like this (without Unions):
@strawberry_django.type(
model=models.User, filters=UserFilter, order=UserOrder, pagination=True
)
class UserType:
id: auto
name: auto
@strawberry.type
class Queries:
@gql.django.connection
async def users(self, info: Info) -> Iterable[UserType]:
return models.User.objects.all()This makes the query look like this:
{
users(first: 5, after: "YXJyYXljb25uZWN0aW9uOjk=") {
edges {
node {
id
name
}
}
totalCount
}
}But my wish would be that the query should be with Unions. So like this:
{
users(first: 5, after: "YXJyYXljb25uZWN0aW9uOjk=") {
edges {
node {
... on User {
id
name
}
... on PermissionProblem {
message
}
}
}
totalCount
}
}If I make the query return a union type, like this:
UsersResult = strawberry.union(
"UsersResult", types=[User, PermissionProblem]
)
@strawberry.type
class Queries:
@gql.django.connection
async def users(self, info: Info) -> Iterable[UsersResult]:
try:
# This function can throw a `PermissionDenied`
return models.User.objects.all()
except PermissionDenied as err:
return PermissionProblem(message=str(err))I get the error message 'StrawberryUnion' object has no attribute '_type_definition'
I hope I have been able to formulate my request in a reasonably understandable way. Is there currently such a possibility?
