How do I localize custom error messages in rails active record validations?

Question

To be specific I was trying to localize the Custom Methods example here. I found a similar question but I don't know how to pass that :message argument in errors.add() method. I tried doing something like this:

errors.add(:discount, message: :greater_than_value_error)

but it prints:

{:message=>:greater_than_value_error}

instead of printing the actual error message that was in the .yml file.

What should be the correct syntax here?

My .yml file looke like this (not sure whether this piece below is 100% accurate):

activerecord: #try to use activemodel here
  errors:
    models:
      invoice: # or namespace/model_name
        attributes:
          discount:
            greater_than_value_error: "can't be greater than total value"

try following errors.add :field_name, :message with rails 4.

errors.add(:discount, :greater_than_value_error)

If you are writing custom validation then you need do actual translation,

errors.add(:discount, I18n.t(path_to_locale_text))

You can internationalize the standard validation messages like predefined validators greater_than_value_error only if you are using built in methods.

validates_numericality_of :discount :greater_than => limit
