Ruby on rails Rails设计-将URL传递到登录

我是否有办法将URL传递到Desive登录页面，以便在用户登录时将其重定向回该URL

比如：

/login?passthru=/somethingawesome

---

还是设置会话变量更好？

在

应用程序\u控制器中有存储重定向位置的方法和访问存储重定向位置的方法：

def store_location(path)
  session[:return_to] = request.request_uri || path
end

def redirect_back_or_default(default)
  redirect_to(session[:return_to] || default)
  session[:return_to] = nil
end

重写方法中的after_sign_，以将用户重定向到所需位置：

def after_sign_in_path_for(resource_or_scope)
  redirect_back_or_default(resource_or_scope)
end

设计维基：如何：

顺便说一句，上面的方法未经测试，您应该对其进行测试。
以下是我所做的

1） 在模板中设置登录名
如下所示：Im passing request.fullpath在这里作为一个例子，你可以用你想要的任何东西替换它

<%= link_to "Log in", new_user_session_path(:passthru => request.fullpath %>

更新更新版本（Ruby 2.2.0、Rails 4.2.0、Desive 3.2.4）：

应用程序\u控制器.rb

  before_action :store_location

  private

  def store_location
    session[:requestUri] = params[:requestUri] if params[:requestUri].present?
  end

  # Custom After Sign in Path
  def after_sign_in_path_for(resource_name)
    if session[:requestUri]
      session.delete(:requestUri)
    else
      super
    end
  end

<%= link_to ('Get This'), some_require_auth_path(@something.id, requestUri: request.fullpath), class: 'button' %>

设计会话\u Controller.rb

  before_action :store_location

  private

  def store_location
    session[:requestUri] = params[:requestUri] if params[:requestUri].present?
  end

  # Custom After Sign in Path
  def after_sign_in_path_for(resource_name)
    if session[:requestUri]
      session.delete(:requestUri)
    else
      super
    end
  end

<%= link_to ('Get This'), some_require_auth_path(@something.id, requestUri: request.fullpath), class: 'button' %>

查看xxxx.html.erb

  before_action :store_location

  private

  def store_location
    session[:requestUri] = params[:requestUri] if params[:requestUri].present?
  end

  # Custom After Sign in Path
  def after_sign_in_path_for(resource_name)
    if session[:requestUri]
      session.delete(:requestUri)
    else
      super
    end
  end

<%= link_to ('Get This'), some_require_auth_path(@something.id, requestUri: request.fullpath), class: 'button' %>
