[RUBY] How to display error messages in Japanese

1. Describe config.i18n.default_locale =: ja

 class Application < Rails::Application
   #Japanese language setting
   config.i18n.default_locale = :ja

Install 2rails-i18n

gem 'rails-i18n'

After writing Terminal bundle install

Japanese registered in rails-i18n https://github.com/svenfuchs/rails-i18n/blob/master/rails/locale/ja.yml

Now I can translate what is written in rails-i18n However, other words have not been translated into Japanese.

3 Create a Japanese localization file for login

config>locales>devise.ja.yml Create a file

Copy the Japanese translation of devise and paste it into the devise.ja.yml you just created https://github.com/tigrish/devise-i18n/blob/master/rails/locales/ja.yml

4 Create a Japanese translation file (ja.yml) for other forms



The nickname of the user table is translated into Japanese The text of the tweet table is translated into Japanese image is translated into Japanese
