app.serializers.role.RoleSerializer.from_dict

classmethod RoleSerializer.from_dict(fields: Dict[str, Union[marshmallow.fields.Field, type]], *, name: str = 'GeneratedSchema') → type

Generate a Schema class given a dictionary of fields.

from marshmallow import Schema, fields

PersonSchema = Schema.from_dict({"name": fields.Str()})
print(PersonSchema().load({"name": "David"}))  # => {'name': 'David'}

Generated schemas are not added to the class registry and therefore cannot be referred to by name in Nested fields.

Parameters

• fields (dict) – Dictionary mapping field names to field instances.

• name (str) – Optional name for the class, which will appear in the repr for the class.
