如何在Rails JSON API中呈现错误代码

Question

I want to render error codes in my error responses as JSON API describes here . I use ActiveInteraction gem and it uses ActiveModel::Errors under the hood for creating error objects. According to the documentation ActiveModel::Errors library just sets an attribute and a message if you want to add an error to your response object.

add(attribute, message = :invalid, options = {})

So how could I set a code property while adding an error?

Here is an extract from the rails api docs:

person.errors.add(:name, :not_implemented, message: "must be implemented")

Actually the ':not_implemented' is the code you need.
