Mutations on proxy models issue
It would seem that mutations on proxy-models aren't working in my setup.
Can you see the mistake in my setup?
A simplified, reproducible example with details included:
Managers:
from django.db.models import Queryset, Manager
class ClientQueryset(Queryset):
def create(self, **kwargs):
kwargs.update({'is_client': True})
return super().create(**kwargs)
class ClientManager(Manager):
def get_queryset(self):
return ClientQueryset(self.model, using=self._db).\
filter(is_client=True)Models:
from django.db import models
from .managers import ClientManger
class Company(models.Model):
name = models.CharField(max_length=100)
is_client = models.BooleanField(default=False)
class Client(Company):
objects = ClientManager()
class Meta:
proxy = TrueBased on this setup, I'm perfectly capable of creating the client objects in the classic ORM way:
from contacts.models import Client
client = Client.objects.create(name='client orm')
print(client.is_client, client.name)Next up, let's setup the strawberry mutations.
schema:
from strawberry import relay, auto
import strawberry
import strawberry_django
from typing import List
from .models import Company, Client
@strawberry_django.filter(Company)
class CompanyFilter:
id: auto
name: auto
@strawberry_django.filter(Client)
class ClientFilter:
id: auto
name: auto
@strawberry_django.input(Company, fields="__all__")
class CompanyInput:
pass
@strawberry_django.partial(Company, fields="__all__")
class CompanyPartialInput(strawberry_django.NodeInput):
pass
@strawberry_django.input(Client, fields="__all__")
class ClientInput:
pass
@strawberry_django.partial(Client, fields="__all__")
class ClientPartialInput(strawberry_django.NodeInput):
pass
@strawberry_django.order(Company)
class CompanyOrder:
name: auto
@strawberry_django.order(Client)
class ClientOrder:
name: auto
@strawberry_django.type(Company, filters=CompanyFilter, order=CompanyOrder, pagination=True, fields='__all__')
class CompanyType(strawberry.relay.Node):
pass
@strawberry_django.type(Client, filters=ClientFilter, order=ClientOrder, pagination=True, fields='__all__')
class ClientType(strawberry.relay.Node):
pass
@strawberry.type
class Mutation:
create_company: CompanyType = strawberry_django.mutations.create(CompanyInput)
create_companies: List[CompanyType] = strawberry_django.mutations.create(CompanyInput)
update_company: CompanyType = strawberry_django.mutations.update(CompanyPartialInput)
delete_company: CompanyType = strawberry_django.mutations.delete()
delete_companies: List[CompanyType] = strawberry_django.mutations.delete()
create_client: ClientType = strawberry_django.mutations.create(ClientInput)
create_client: List[ClientType] = strawberry_django.mutations.create(ClientInput)
update_client: ClientType = strawberry_django.mutations.update(ClientPartialInput)
delete_client: ClientType = strawberry_django.mutations.delete()
delete_client: List[ClientType] = strawberry_django.mutations.delete()
@strawberry.type
class Query:
company: CompanyType = strawberry_django.node()
companies: strawberry_django.relay.ListConnectionWithTotalCount[CompanyType] = strawberry_django.connection()
client: ClientType = strawberry_django.node()
clients: strawberry_django.relay.ListConnectionWithTotalCount[ClientType] = strawberry_django.connection()
schema = strawberry.Schema(
query=Query,
mutation=Mutation,
)Now that the schema is setup, let's run some mutations:
First, the base model "Compay":
mutation createCompany{
createCompany(data:{name: "company"}){
name
isClient
}
}yields, successfully
{
"data": {
"createCompany": {
"name": "company",
"isClient": false
}
}
}Now, let's try the proxy-model:
mutation createClient{
createClient(data:{name: "client"}){
name
isClient
}
}Yields, unsuccessfully:
{
"data": null,
"errors": [
{
"message": "Client matching query does not exist.",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"createClient"
]
}
]
}Can you see the mistake in my setup?
