重定向到當前頁面

Question

我有一個在rails 4中帶有重定向的問題。我需要重定向到在特定情況下指定的頁面。 向后重定向不起作用，因為我需要重定向的頁面不是上一頁，並且僅在用戶單擊鏈接時才需要重定向到該頁面。 代碼：查看用戶單擊的位置：

<li >
  <%= link_to new_admin_wine_path do %>
    <span>
      Cadastrar um novo vinho
    </span>
  <% end %>
</li>

單擊該鏈接時需要重定向到的頁面：new_admin_wine_path

控制器：

def store_location
    return unless request.get?
    if (request.path != new_user_session_path &&
        request.path != new_user_registration_path &&
        request.path != new_user_password_path &&
        request.path != edit_user_password_path &&
        request.path != "/:locale/users/confirmation(" &&
        request.path != destroy_user_session_path &&
        !request.xhr?) # don't store ajax calls
      session[:previous_url] = request.fullpath
    end
  end
  def after_sign_in_path_for(resource)
    session[:previous_url] || root_path    
  end

您應該查看過濾器 。 基本上，您將要構造控制器：

class someController < ActionController::Base
    after_filter :redirect_method, only: [:whatever, :actions, :you, :want]
    def store_location
        return unless request.get?
        if (request.path != new_user_session_path &&
            request.path != new_user_registration_path &&
            request.path != new_user_password_path &&
            request.path != edit_user_password_path &&
            request.path != "/:locale/users/confirmation(" &&
            request.path != destroy_user_session_path &&
            !request.xhr?) # don't store ajax calls
          session[:previous_url] = request.fullpath
        end
      end
      def after_sign_in_path_for(resource)
        session[:previous_url] || root_path    
      end
     def redirect_method
        redirect_to root_path (or whevever you want to send them) 
     end
end
