What i understand

Suppose I have a class with convenient validation, for example:

User < ActiveRecord::Base
    validates :username, :format => {/regex/}, :message => :name_format
end

In this case, I can use i18nto make the error message translated by including the following in mine /config/locals/en.yml:

en:
    activerecord:
        errors:
            models:
                user:
                    attributes:
                        username:
                            name_format: 'has the way-wrong format, bro!'

This is normal and generally very convenient.

What I want to know:

My question is: what happens when I have subclasses inheriting from the user:

UserSubclassOne < User
    # extra stuff
end
UserSubclassTwo < User
    # extra stuff
end
...
UserSubclassEnn < User
    # extra stuff
end

Now the problem is that Rails cannot find the translation user_subclass_one.attributes.username.name_format.

He complains:

translation missing:
en.activerecord.errors.models.user_subclass_one.attributes.username.name_format

I hope that Rails will look up the hierarchy UserSubclassOnebefore Userwhen searching for the string in en.yml, and then notice when it gets a “hit”, but (if I didn’t do something terribly wrong), apparently this does not happen.

en.yml.en.errors.models User, user_subclass_one, user_subclass_two .., Rails , .

:

User gem MyGem, Rails MyEngine, Rails MyApp, UserSubclassOne,..., UserSubclassEnn, , , MyGem::User, en.yml, - , , .

, en.yml : /config/locals/en.yml:

en:
    activerecord:
        errors:
            models:
                my_gem/user:
                    attributes:
                        username:
                            name_format: 'has the way-wrong format, bro!'
