Rails Validation - Remove or Modify Nested Model Names-CodePudding

I have a few name-spaced Models, with relationships to each other as such:

my_ns/main.rb

module MyNs
  class Main < ApplicationRecord
    has_many :secondary

    accepts_nested_attributes_for :secondary, allow_destroy: true
  end
end

my_ns/secondary.rb

module MyNs
  class Secondary < ApplicationRecord
    belongs_to :main
    has_many :tertiary

    accepts_nested_attributes_for :tertiary, allow_destroy: true
  end
end

namespace/tertiary.rb

module MyNs
  class Tertiary < ApplicationRecord
    belongs_to :secondary

    validate :custom_method

    private

    def custom_method
      errors.add(:thing, :custom_method_translation) if # condition
    end
  end
end

I then have a form that lets me add a main, multiple secondary and tertiary instances. This all works great, until I try to validate that custom_method. When the validation fails, and errors.add(:thing, ...) is triggered, the validation message appears as such:

Secondary tertiary thing is not valid.

Basically, I want this to say "Tertiary's thing is not valid." I've seen this Stackoverflow answer which alludes to using ActiveRecord's i18n

config/locales/en.yml:

en:
  activerecord:
    attributes:
      main_model/nested_model:
        key: 'Key'

The thing is, my models are nested more than 1 level, and have namespaces. I've tried things like:

en:
  activerecord:
    attributes:
      my_ns/main/secondary/tertiary:
        thing: 'Thing'

# OR

en:
  activerecord:
    attributes:
      my_ns/main/my_ns/secondary/my_ns/tertiary:
        thing: 'Thing'

# OR

en:
  activerecord:
    attributes:
      my_ns/main:
        my_ns/secondary:
          my_ns/tertiary:
            thing: 'Thing'

And nothing has worked... The error message still appears as "Secondary tertiary thing is not valid".

Does anyone know how to handle this with nested, namespaced Models? Is this something that can be handled? Alternatively, if there's a way to stop Rails from attempting to prepend the Model chain, that would work too. I just need the error to say "Thing is invalid", or "Tertiary's thing is invalid", etc. I don't want to see "Secondary tertiary ..."

You can check this issue https://github.com/rails/rails/issues/19863 it looks similar to yours.

Instead of adding complete chain from top model, try directly adding from the secondary model

en:
  activerecord:
    attributes:
      secondary/tertiary:
        thing: 'Thing'
