Я использую страны драгоценных камней для заполнения элемента выбора страны. Я хотел бы добавить страны, не включенные в список стран ISO3116, предоставленные драгоценным камнем.Загрузка пользовательских данных в жемчужину Hexorx/страны в рельсах 4.2
Gem: https://github.com/hexorx/countries
Я прочитал вики для стран камня. Я попытался выполнить инструкции, указанные в разделе «Загрузка пользовательских данных». к сожалению, они слишком скудны для родственника новичков, таких как я.
Когда я пытаюсь загрузить сервер разработки, я получаю ошибку, указанную ниже.
Я не знаю, где я должен добавить следующий код. Я добавил его в «config/initializers», потому что согласно руководствам (http://guides.rubyonrails.org/initialization.html) файлы в этом каталоге загружаются после файлы gem загружаются при инициализации приложения. Следовательно, мое замешательство. К моменту выполнения кода ниже не должна быть инициализирована константа «ISO3116»?
Код:
конфигурации/Инициализаторы/custom_countries.rb
ISO3116::Data.register(
continent: "Europe",
alpha2: "EN",
alpha3: "ENG",
name: "England"
)
