我们正在将我们的 Rails 应用程序从 4.1 升级到 4.2。

虽然此代码在 4.0 和 4.1 中运行良好：

admin_root_url(:subdomain => 'www')

当我在 4.2.3 上尝试时，我收到此错误：

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 看起来像这样：

控制台中的堆栈跟踪：

    from bin/rails:4:in `<main>'

================ edit（2）=================
我跳入了代码中，看到了 /gems /activepack中的行引发错误的-4.2.4/lib/action_dispatch/routing/route_set.rb（282）是：

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

而url_rewriterurl_for中的函数签名是：

def url_for_with_subdomains(options, path_segments=nil)

看起来我需要更新一些东西，但我不知道是什么。

================编辑（3）===============只是为了确保它与我的文件
无关，我routes.rb清理它并像这样离开它：

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

正如预期的那样，仍然有同样的错误。

In case you get that error in the console, because you use a helper that uses URL helpers:

class << helper; include Rails.application.routes.url_helpers; end
helper.my_method # \o/

我有完全相同的问题，最后在我的情况下

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

url_for_with_secure_option从bartt-ssl_requirement宝石调用。

由于在我们的案例中不再需要bartt-ssl_requirementgem，因此我们的解决方案是简单地删除bartt-ssl_requirementgem。

在需要时尝试删除subdomain-fu并使用 Rails4 request.subdomain。

有同样的问题，解决方案是而不是使用：

include Rails.application.routes.url_helpers

我没有将 url_helpers 添加到变量中，如下所示：

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