Unable to find input class EncryptedInput Error

[denys-husiev-perfectial]

Hello.
After updating formtastic from 3.1.5 to 4.0.0 I have the following error: Unable to find input class EncryptedInput
It appears for field which is encrypted in ActiveRecord model

form.input :field_name, label: "Field" # raises an error

class MyModel < ActiveRecord::Base
  attribute :field_name, :encrypted
end

It is fixed when I explicitly specify form.input :field_name, label: "Field", as: :string.
As I understand, the error appears because of updated method Formtastic::Helpers::InputHelper#column_for which calls type_for_attribute(instead of column_for_attribute) after update and returns encrypted(instead of string)

P.S. Using formtastic as dependency of ActiveAdmin

Hi,

I think thats intended. Formtastic 4 understands Rails 5+ Attributes API. Formtastic 3 didn't, so it defaulted to strings.

This allows you for example to define an attribute attribute :check, :boolean and be rendered as a checkbox. It is like you'd have a column in database of type encrypted. Formtastic behaves the same for these virtual attributes as for real ones.

This also allows you to define a EncryptedInput that handles your specific input in case it is not just plain string (you want some code editor for example).

Formtastic currently does not support easy type aliases for inputs, but you can always override and adjust this method if you need to do it.
