Rails 4.2 - url助手引发"ArgumentError:错误的参数数(1..2的3)“

Question

我们正在将Rails应用程序从4.1升级到4.2。

虽然这段代码在4.0和4.1中运行得很好：

admin_root_url(:subdomain => 'www')

当我在4.2.3上尝试时，我会得到以下错误：

ArgumentError: wrong number of arguments (3 for 1..2)

我在控制台中检查了几次，运行以下代码：

include Rails.application.routes.url_helpers
default_url_options[:host] = "localhost"
root_url

我们的Gemfile看起来如下：

================编辑(2) ===============

我深入研究了代码，并看到/gems/actionpack-4.2.4/lib/action_dispatch/routing/route_set.rb (282)中引起错误的行是：

t._routes.url_for(hash, route_name, url_strategy)

而url_for函数在url_rewriter中的签名是：

def url_for_with_subdomains(options, path_segments=nil)

看来我需要更新什么，但我不知道是什么。

================编辑(3) ===============

为了确保它与我的routes.rb文件无关，我清理了它，并将它保留如下：

MyApp::Application.routes.draw do
  root 'pages#index', :constraints => {:subdomain => /www|$^/}
end

正如预期的那样，仍然存在相同的错误。

Answer 1

由于同样的问题，解决方案不是使用：

include Rails.application.routes.url_helpers

我不包括并将url_helpers添加到变量中，如下所示：

url_helpers = Rails.application.routes.url_helpers
url_helpers.root_url

Answer 2

我也有同样的问题，在我的案子的最后

t._routes.url_for(hash, route_name, url_strategy)

名为url_for_with_secure_option，来自bartt-ssl_requirement宝石。

由于我们不再需要bartt-ssl_requirement gem，所以我们的解决方案就是简单地删除bartt-ssl_requirement gem。

Answer 3

尝试删除subdomain-fu并在需要时使用Rails4 request.subdomain。
