如何使用Rails I18n.t翻译ActiveRecord属性？

gem 'i18n'

config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '**', '*.{rb,yml}')]
config.i18n.default_locale = :en

en:
  activerecord:
    attributes:
      user:
        name: "Name"
        email: "Email"

<%= f.label :name, I18n.t("activerecord.attributes.user.name") %>
<%= f.text_field :name %>

<%= f.label :email, I18n.t("activerecord.attributes.user.email") %>
<%= f.email_field :email %>

def create
  @user = User.new(user_params)
  if @user.save
    flash[:success] = I18n.t("activerecord.attributes.user.name") + " " + I18n.t("activerecord.attributes.user.email") + " " + I18n.t("created_successfully")
    redirect_to @user
  else
    render 'new'
  end
end
