How to create a field to expose Model Fields' choices #471
Description
I have a model field with choices:
CHOICES = [
('foo', 'Foo'),
('bar', 'Bar'),
]
class MyModel(models.Model):
ham = models.CharField(max_length=2, choices=CHOICES)
So, in the schema I have the model and its choices. But can I expose the choices ?
I tried this but without success:
MyModelHamType = registry.get_converted_field(models.MyModel._meta.get_field('ham')).get_type()
class Query(object):
choices = graphene.Field(MyModelHamType)
def resolve_choices(self, info, **kwargs):
# What to do here
return MyModelHamType
The code above gives the following thing:
Request :
query {
hams
}
Response:
{
"errors": [
{
"message": "Expected a value of type \"MyModelHam\" but received: MyModelHam",
"path": [
"hams"
]
}
],
"data": {
"hams": null
}
}
It seems that as the object aren't the of the same type (Pythonicly saying), Graphene doesn't want to handle.
I could recreate myself a MyModelHamType with Enum, but it will be duplicate with the existing one autocreated and already in schema.
