I have a tables with content in two languages. Then I have a column called 'language' to distinguish.Now I use I18n to do multi languages website.So, how can I get content in database with current language?
I think that if I can set the default_scope of model accoding to the language, or load different models the same name.
Thank you!
You can use a URL parameter to set the application locale for a request, for example:
# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
before_action :set_locale
def set_locale
I18n.locale = params[:locale] || I18n.default_locale
end
end
Find the model by current locale:
YourContent.where(name: some_name, language: I18n.locale)
and use the t method in views with your strings files since you have the application locale set.
The docs have a few other examples.
Yes, you can use default_scope { language: I18n.locale } to omit the extra where, but be aware of the caveats of default_scope.
If you want to switch to different table conditionally for same model, you can use ActiveRecord::Base.table_name class method.
Example:
cTable4 ❯ rails c -e production
Running via Spring preloader in process 60375
Loading production environment (Rails 4.2.4)
irb(main):001:0> Book.first
Book Load (0.1ms) SELECT "books".* FROM "books" ORDER BY "books"."id" ASC LIMIT 1
=> #<Book id: 1, name: "ELoquent Ruby", author: "Russ", year: "2011", created_at: "2016-01-07 08:40:47", updated_at: "2016-01-07 08:40:47">
irb(main):002:0> Book.table_name = 'titles'
=> "titles"
irb(main):003:0> Book.first
Book Load (0.2ms) SELECT "titles".* FROM "titles" ORDER BY "titles"."id" ASC LIMIT 1
=> #<Book id: 1, title: "Practical OOD Ruby", author: "Sandi Metz">
irb(main):004:0>
