Question

当在浏览器中加载这些部分内容时，我无法通过浏览器后退按钮离开页面。页面保持不变，但网址会更改。

导致这种情况的原因是什么？

  match '/signup',  to: 'users#new',            via: 'get'
  match '/signout', to: 'sessions#destroy',     via: 'get'


# /users/new
  def new
    @user = User.new
    render partial: "new", layout: false
  end

# /sessions/new
  def new
    render partial: "new", layout: false
  end

这是我的筹码。这只需点击登录链接一次。

Answer 1

您是否有过滤器重定向公共访问会话#new？您是否定义/签署了路线？

Answer 2

我可能错了，但正如我在评论中写的那样，我有一个客户在Rails 3.2.12上使用Turbolinks和一组定制的JS库。 Turbolinks引发了许多问题，例如双重提交，其中一个与你提到的类似。我有3个选择：

1-取出Turbolinks（我的临时解决方案，直到我展示团队TL导致它）

2-更改JS lib依赖项

3-将Rails应用程序更新到最新的4.x. （我最后这样做了，这不是太糟糕）

如果我错了，你的案例和设置与我的不相似，那么Github上有一个很好的线程，有些人试图解决它并且似乎仍然是开放的。

检查参数：

Processing SESSION::SESSION#new (for 127.0.0.1 at 2014-04-04 13:50:03) [POST]
Parameters: {"authenticity_token"=>"XXXXX=", "param1"=>"1"}

在您的日志中，如果根据您的列或您想要保留的内容未发送您想要创建的参数，您将看到正在发送的参数。

如果你想创建一个后退按钮，你可以试试这个：

link_to_function "Back", "history.back()"

检查您的行动表格，也许您正在发送其他网址

  <% form_tag :controller=>"sessions",:action=>"new" do %>
    <% @user.each do |user| %>
      <%= user.name %>
      <%= user.lastname %>
    <% end %>
  <% end %>
