Granitizer add flexibility in the GraphL mutation input to define filter input and payload input To be used aside of graphene-python Detailed documentation is in the "docs" directory.
Add "django-granitizer" to your INSTALLED_APPS setting like this:
INSTALLED_APPS = [ ... 'django-granitizer', ]
from django-granitizer.granitizer import Granitizer class ObjectGranitizer(Granitizer):
- class Meta:
graphene_class = ObjectNode serializer_class = ObjectSerializer #if using relay.Node relay_id_fields = {
"type" : BTypeNode, "target" : BTargetNode, "id" : BusinessNode} filter_key = {
"dict": [{"key":"filter"}], "uniq":[{"key":"id"}]} payload_key = {"dict": [{"key":"data"}]}
- Model
- class Object(models.Model):
- name = models.CharField(max_length=100) description = models.TextField()
- Graphene Object Type
- class ObjectDataInput(DjangoInputObjectType):
- class Meta:
- model = Object
- class ObjectFilter(InputObjectType):
- name = String()
- class ObjectInput(InputObjectType):
- id = graphene.ID() filter = ObjectFilter() data = ObjectDataInput()
