acts_as_tree和rails 3.2.3不兼容？

我正在使用Rails 3.2.3和acts_as_tree 1.1.0。我一直使用acts_as_tree来处理早期版本的Rails 3（比如3.1.1）的一些不同的项目，但没有任何问题，但对于这个版本根本不起作用。如果是因为3.2.3或其他我使用的东西，我还没有能够确认。acts_as_tree和rails 3.2.3不兼容？

这是我已经试过了，没有用： - 对几个不同的控制器使用acts_as_tree - 只有使用acts_as_tree（没有order语句） - 运行包安装包更新 - 仔细检查PARENT_ID存在，是整数

首先，当我尝试这样做，在我第一次尝试了：

undefined method `acts_as_tree'

重新加载页面（而不是做别的）引起的：

undefined method `key?' for nil:NilClass

然后重新启动服务器造成发射失败（应用程序会崩溃和无法启动），出现以下错误：

这让我想有一个保持兼容问题BTW的Rails 3.2.3和acts_as_tree。我不知道如何验证这一点。

我有什么选择？我不一定需要使用Rails 3.2.3，但是如果我降级到3.1.1。（我试过）我遇到了其他更糟糕的问题（“文件设置”似乎不一样）。

那么，我有什么选择？你有没有体验过这个？ acts_as_tree有问题，对吗？

貌似有一个从2年前开放

opened this issue 2 years ago Does not work with Rails 2.3.8 https://github.com/rails/acts_as_tree/issues/1

选项

acts_as_tree_rails3 gem install acts_as_tree_rails3

或

nested_set https://github.com/skyeagle/nested_set

你是对的，新的位置是https://github.com/amerine/acts_as_tree同一作者

与评论

We no longer support Ruby 1.8 or versions if Rails/ActiveRecord older than 3.0. If you're using a version of ActiveRecord older than 3.0 please use 0.1.1.

Moving forward we will do our best to support the latest versions of ActiveRecord and Ruby

这就是为什么他们不使用acts_as_tree_rails3的伎俩那些打开的问题

打扰。我看不出你所链接的问题是如何相关的。从未听说过acts_as_tree_rails3，并且不需要将其用于3.1.1。但我很高兴它的工作。谢谢！ – Christoffer

谢谢它适合我。 –
