This release adds field support for permissions

import strawberry

from strawberry.permission import BasePermission

class IsAdmin(BasePermission):
    message = "You are not authorized"

    def has_permission(self, info):
      return False

@strawberry.type
class Query:
    @strawberry.field(permission_classes=[IsAdmin])
    def hello(self, info) -> str:
      return "Hello"

This releases adds support for ASGI 3.0

from strawberry.asgi import GraphQL
from starlette.applications import Starlette

graphql_app = GraphQL(schema_module.schema, debug=True)

app = Starlette(debug=True)
app.add_route("/graphql", graphql_app)
app.add_websocket_route("/graphql", graphql_app)

Added support for optional fields with default arguments in the GraphQL schema when default arguments are passed to the resolver.

Example:

@strawberry.type
class Query:
   @strawberry.field
   def hello(self, info, name: str = "world") -> str:
       return name

type Query {
    hello(name: String = "world"): String
}

Fixed issue that was prevent usage of InitVars.
Now you can safely use InitVar to prevent fields from showing up in the schema:

@strawberry.type
class Category:
    name: str
    id: InitVar[str]

@strawberry.type
class Query:
    @strawberry.field
    def category(self, info) -> Category:
        return Category(name="example", id="123")

Fixed logo on PyPI

Added support for passing resolver functions

def resolver(root, info, par: str) -> str:
    return f"hello {par}"

@strawberry.type
class Query:
    example: str = strawberry.field(resolver=resolver)

Also we updated some of the dependencies of the project

Added support for renaming fields. Example usage:

@strawberry.type
class Query:
    example: str = strawberry.field(name='test')

Added support for declaring interface by using @strawberry.interface
Example:

@strawberry.interface
class Node:
    id: strawberry.ID

This changes field to be lazy by default, allowing to use circular dependencies
when declaring types.
