Ariadne Codegen 0.12

February 5, 2024

Ariadne Codegen 0.12 has been released!

This is a maintenance release that fixes reported bugs in Pydantic models creation, subscriptions, plugins and adds support for saving schema to graphql file.

Fixed graphql-transport-ws protocol implementation not waiting for the connection_ack message on new connection

Async client for graphql-transport-ws protocol didn't await for the connection_ack message on the new connection to the GraphQL server.

This has been addressed in Ariadne Codegen 0.12.

Fixed get_client_settings mutating config_dict instance

Ariadne Codegen mutated config_dict on initialization, which caused errors when plugins attempted to access changed or removed keys in the configuration dict.

In 0.12 config_dict is first copied before being changed, preserving the original dict for plugins.

Restored model_rebuild calls for top level fragment models

model_rebuild calls were previously removed from Ariadne Codegen to improve the generated client's initialization performance.

This caused an issue where lazy references were not completed by Pydantic on initialization, breaking those in the client.

0.12 attempts to detect scenarios where model_rebuild are necessary and includes them in the generated client.

Added support to graphqlschema for saving schema as a GraphQL file

Ariadne Codegen provides the graphqlschema command which creates a local copy of specified schema.

Previously this copy was always a Python declaration of the GraphQLSchema instance, but since 0.12 it is now possible to create a copy in GraphQL Schema Definition Language.

Output format is controlled by the file extension used in the target_file_path configuration option:

• .py will produce a Python file with GraphQLSchema instance.
• .graphql and .gql will produce a GraphQL file with SDL schema definition.
