每当我尝试创建或更新我们的应用程序使用的环境时，我都会得到以下信息：

NoMethodError (undefined method `base_url' for #<HashWithIndifferentAccess:0x107162f08>):

正如我在标题中所说，我最近升级到 Rails 2.3.11。这个错误以前从未发生过。这是我的environments_controller.rb中发生错误时正在执行的代码：

def check_base_url_for_https
  @environment = params[:environment]
  if /^https:\/\//i =~ @environment.base_url 
    @ajax_flash = "<ul class='notice'><li>The website you are trying to test is a secure site.  If you are using self-signed SSL certificates please see our <a href='http://support.janova.us'>Support Site</a> and search for SSL for important tips on how to access your site.</li></ul>"
  end
end

有谁知道为什么这段代码（特别是该行在if /^https:\/\//i =~ @environment.base_urlRails 2.3.11 中不再有效？

我想补充一点，我的 app/models/environment.rb 中的代码似乎也很合理：

def base_url 
  self[:base_url].try(:gsub, /\$/, '') 
end

有人看到上面的代码有什么问题吗？

我想通了：params[:environment]被定义为哈希。谢谢你，弗罗斯特，强迫我看到这个。因此，我将线路更改@environment = params[:environment]为@environment = Environment.new(params[:environment])并且它有效。
