}

Usage

python3 manage.py configure-schema <app_label.ModelName1> <app_label.ModelName2> <app_label.ModelNameN> -in <my_graphql_app_label> -fl <flavor_name>

Arguments

Required

1. list of models in form of app_label.ModelName
2. --in-app, -in: the app_label where the schema modules will be generated
3. --flavor, -fl, --workflow, -wfl: the name of the workflow that will generate the necessary modules

Optional

1. --package-name, -pn: the name of the package, defaults to gql
2. --overwrite, -owt: if true, will overwrite everything

Falvors/Workflows

This addon comes with the following flavors:

• relay_queries: generates relay style types(nodes), query, filter, order
• relay_mutations: generates relay style create/partial-update input types, mutations
• query_set_managers: A simple class with get_queryset, to help manage querysets in one place, normally not needed
• tests: coming soon

IMPORTANT!

Running a flavor with overwrite flag will replace the necessary modules made with other flavors to work with the currenty run flavor.

Under the hood and things to know

StrawberryJamTemplate

The addon has implemented a simple StrawberryJamTemplate class. The command looks for modules in the chunks/flavor_name/templates/ and initializes the Template subclass of StrawberryJamTemplate, which generates the necessary modules in the schema.

Mutations

The relay_mutations flavor comes with extra. Instead of exposing to-many relations as a field, it exposes them via <field_name>_add and <field_name>_remove fields of type list[GlobalID], which let add remove fields by simply passing ids that need to be added or removed.

TODO

• Add generation of test modules
• Maybe add ability to run multiple flavors consecutively
• The generated schema will not work, if the types for relations are not generated. So maybe skip the fields for models that are not supplied to the command.
