Rails Json具有多语言响应

Question

I have a Controller that has a mobile client, the response currently are in English, however im questioning if there's a way to customize the language of the response.

Ex:

English: { "success": false, "message": "Error with your login or password" }

Spanish:{ "success": false, "message": "Error con tu usuario o contraseña" }

and of curse the content of the "message" is gonna be located in the language configuration file that rails has:

en.yml

or

es.yml

and this is the function where the response is generated.

def invalid_login_attempt
    warden.custom_failure!
    render :json => { :success => false, :message=> "Error with your login or password" }, :status => 401
  end

Thanks.

Answer 1

Have you tried I18n.t ?

render :json => { :success => false, :message=> I18n.t('your_key') }, :status => 401

And you can set the locale for every request in ApplicationController based on some criteria, like for example

before_action :set_locale

def set_locale
  I18n.locale = request.headers["X-Lang"] || I18n.default_locale
end

Answer 2

Setting up internationalization (I18n) for Rails should be pretty much the same for HTML and JSON responses. Have a look at the official tutorial .
