GraphQL API

Defining the Schema Class

A plugin can extend NetBox's GraphQL API by registering its own schema class. By default, NetBox will attempt to import graphql.schema from the plugin, if it exists. This path can be overridden by defining graphql_schema on the PluginConfig instance as the dotted path to the desired Python class. This class must be a subclass of graphene.ObjectType.

Example

# graphql.py
from typing import List
import strawberry
import strawberry_django

from . import models


@strawberry_django.type(
    models.MyModel,
    fields='__all__',
)
class MyModelType:
    pass


@strawberry.type
class MyQuery:
    @strawberry.field
    def dummymodel(self, id: int) -> DummyModelType:
        return None
    dummymodel_list: List[DummyModelType] = strawberry_django.field()


schema = [
    MyQuery,
]

GraphQL Objects

NetBox provides two object type classes for use by plugins.

::: netbox.graphql.types.BaseObjectType options: members: false

::: netbox.graphql.types.NetBoxObjectType options: members: false
