[FEATURE] Use existing marshmallow schema
Description
I already have (flask) Schema classes defined:
class UserIn(Schema):
"""Fields for user when requesting a new account in admin."""
username = fields.Str(
required=True, validate=validate.Length(min=4, max=254)
)
password = fields.Str(
required=True, validate=validate.Length(min=8, max=16)
)
I also have a dataclasses_json equivalant:
@dataclass_json
@dataclass
class InUser:
"""New user account dataclass."""
username: str
password: str
I want to re-use the UserIn
for loading InUser
. but it appears InUser.schema()
does not take the already defined one?
Am I missing some subtle aspect for this?
Possible solution
No response
Alternatives
To cache the whole thing
_in_user_setup = InUser.schema(UserIn)
And deserializing from dictionary (or json)
new_user:InUser = _in_user_setup.load({...})
