ActiveModel validaitons not working

[freiden]

Hi,

In my project, when using:

extend ActiveModel::ModelValidations

 copy_validations_from Model

The validations from my models are not backported to the Form.

After taking a look at the code it seems like the issues is coming from Mapping.from_representable_attrs(definitions) in the copy_validations_from method, definitions is always returning {} which prevent the mapping of the attributes in from_representable_attrs and prevent the method inverse_image to return any value.

Did I miss an element to set to make the validations work?

Hi! Ideally, you'd patch this because this feature has been abandoned for a long time - can you find out what went wrong and help us with it? 😍

@apotonick Is it only this part of the implementation or the AR in it's totality?

[apotonick]

Only the copying, everything else works fine! Thanks!

@apotonick I will try to make fix/patch for this and then make a PR for it.
