[w-zygmuntowicz]

System configuration

ruby 3.3.5 (2024-09-03 revision ef084cc8f4) [x86_64-linux]
Rails 7.2.1
motor-admin 0.4.31

Description

When trying to upload files for a model with has_many_attached option set the 500 error appears inside the browser inspector and the files are not saved. It is possible to save files when using has_one_attached option.

Error

POST http://localhost:3000/motor_admin/api/data/active_storage__attachments
500 Internal Server Error

Response

The update action could not be found for the :wrap_io_params
callback on Motor::ActiveStorageAttachmentsController, but it is listed in the controller's
:only option.

Raising for missing callback actions is a new default in Rails 7.1, if you'd
like to turn this off you can delete the option from the environment configurations
or set config.action_controller.raise_on_missing_callback_actions to false.
