Why aren't custom error_messages supported for the `load` and `loads` methods on Schema?

See original GitHub issue


Why does this code only support dump and dumps?

Validation happens on load and loads too, so presumably it makes sense for me to able to overload those messages with the same class variable too, no?

Ah thanks. Fixed

“Required” validation is field-level, not schema-level, so you need to set the default error messages on Field.

from marshmallow import Schema, fields

fields.Field.default_error_messages["required"] = "boom!"

class ArtistSchema(Schema):
    name = fields.Str(required=True)

print(ArtistSchema().validate({}))  # {'name': ['boom!']}

@lafrech The docs appear correct. Am I missing something?
