Question

我试图在我的rails项目中为多语言实现i18n。部分它有效，例如。在导航中，它是application.html.erb的一部分，并按如下方式实现：

<%=t :about %>

application.rb的结构如下：

require_relative 'boot'
require 'rails/all'
Bundler.require(*Rails.groups)

module Regional
  class Application < Rails::Application
    I18n.available_locales = [:en, :de]
    I18n.default_locale = :en
  end
end

application_controller.rb如下所示：

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :set_locale

  private

  def set_locale
    I18n.locale = params[:locale] || I18n.default_locale
  end

  def default_url_options(options = {})
    {locale: I18n.locale }.merge options
  end
end

着陆页的主体位于另一个文件index.html.erb中，i18n的使用方式如下：

<div class="section-title text-center center">
    <div class="overlay">
      <h2><%=t :regionalTitle %></h2>
      <hr>
      <p><%=t :regionalSubTitle %></p>
    </div>
  </div>

但是网站只显示变量而不是值，而不是获得正确的翻译： i18n doesnt show value

信息更新：它甚至不会显示英文文本。

我也尝试将i18n控制器代码用于着陆页，但没有帮助

    private 
    def set_locale
        I18n.locale = params[:locale] || I18n.default_locale
      end

      def default_url_options(options = {})
        {locale: I18n.locale }.merge options
      end

更新：这是日志文件。首先，当我只是重新加载文件时，第二次选择英语时。

更新：文件夹的路径和层次结构。Hierarchy and file name

似乎params[:locale]似乎是nil，因此您I18n.default_locale将:en作为default_locale。因此，您看到普通文本（:en）而不是翻译文本（:de）。

您可以通过发送如下所示的显式值来调试它，以确保params[:locale]为nil。

def set_locale
  I18n.locale = 'de' || I18n.default_locale
end

Rails i18n显示变量但不显示值（翻译）
