Translation for schema keys

[marcotas]

Maybe this is a dumb question but I really didn't find it anywhere in the documentation.

How can I translate a Schema field name? Example:

UserValidation = Dry::Validation.Schema do
  configure { config.messages = :i18n }

  required(:age).filled
end

When I want the full messages i got the message translated correctly, but not the field name.
age obrigatório(a). I didn't find the translation key for 'age', which should be 'idade' of the translated name.

Maybe the yml file should have something like this?

pt_BR:
  errors:
    fields:
      age: Idade

Sorry about my english. To be clearer I want to know the translation key to be able to translate the Schema fields. If I have required(:name).filled I want to setup my i18n yml file to have 'name' translated in the full messages validations.

Thanks for everything and congratulations for the excelent lib! 👍

I was also wondering whether there was a good way to do this. I have monkey patched myself a solution for now, but would rather have a supported solution if possible.

@cmcolinh would you share that? this is mind-boggling.

Monkey patch this in (I put in in config/initializers/)

def extract_all(key, h)
  r = []
  h.each do |k, v|
    if v.is_a? Hash
      r += [extract_all("#{key}.#{k}", v)].flatten(1)
    else
      r << [:"#{key}.#{k}", v]
    end
  end
  r
end

module Dry
  module Validation
    class Result
      def validation_errors(locale: :en)
        err = {}
        self.errors(locale: locale).map do |k, v|
          if v.is_a? Hash
            err.merge!(extract_all(k, v).to_h)
          else
            err[k] = v
          end
        end

        err.map do |k, v|
          if v[0].is_a?(String)
            [AppDef[k]&.[](:rails) || k, "#{AppDef[k]&.[](locale) || "#{k} "}#{v[0]}"]
          else
            return_value = []

            v.values.each do |a|
              return_value << "#{AppDef[k]&.[](locale)}#{a[0]}"
            end

            [AppDef[k]&.[](:rails), return_value.join("\r\n")]
          end
        end.to_h
      end
    end
  end
end

Where AppDef was written in YAML with an example of

ball:
  es: "pelota"

I see no reason why the i18n file could'nt be used instead.
Then call using

s.call(params).validation_errors(locale: :es)

It's customized for my specific needs of course(to create newline delimited errors that I can raise as is, it's also flattening the error keys as well, which you may not want), but you can probably change this to fit your needs as well.

this will get me going. thank you.

I'm also interested in this. Any inbuild solution to that?

i was poking around the code yesterday and tonme it looks like there‘s supposed to be built-in support for that. but the kay path lookup fails for the i18n adapter. i‘ll try have a look at the test suite and wether i can put sth together.
