Dynamic Strawberry Types with dynamic fields

[cabal-daniel]

Hello, we are exploring Strawberry as an option of our application. We have several DynamoDB single-tenant database deployments for an object say "users". The users table has 10 columns that are the same between each deployment but there are more than 20 other columns that can be different.

For example in Deployment 1 the users table has columns/fields:

• friends
• last_logged_on

Deployment 2 might have

• siblings
• cousins

Therefore we have to determine the schema for Strawberry at runtime. Is there any documentation on this? We've tried several options suggested through GPT and looked into "hacking" into the StrawberryDefinitions class. The problem is that the return type of a query field must be compatible with Strawberry

@strawberry.type
class Query:

    @strawberry.field
    def hello(self) -> str:
        return "Hello"

    @strawberry.field
    def all_users(self) -> typing.List[FullUser]:
        return []

    @strawberry.field
    def get_dynamic_types(self) -> Any:
       return []

The last get_dynamic_types is incompatible as Any is not supported.

Description

Looks like there's many an opportunity to override the Schema class?

class CustomSchema(strawberry.Schema):
    def get_fields(
        self, type_definition: StrawberryObjectDefinition
    ) -> List[StrawberryField]:
        if type_definition.name == 'FullUser':
            type_definition.fields.append(
                strawberry.field(name='custom_field', resolver=custom_field_callback)
            )
        return type_definition.fields

It looks like the above works but will require a restart of the server if the schema changes.
