Question

我正在使用Rails 3.2.3和acts_as_tree 1.1.0。我一直在使用acts_as_tree与早期版本的Rails 3（例如3.1.1。）进行一些不同的项目，没有任何问题，但是对于这个版本它根本不起作用。如果是因为3.2.3或我使用的其他东西，我无法确认。

这是我试过的，无济于事： - 在几个不同的控制器上使用acts_as_tree - 仅使用acts_as_tree（没有订单声明） - 运行bundle install和bundle update - 仔细检查parent_id是否存在且是整数

首先，当我尝试这个时，我首先尝试：

undefined method `acts_as_tree'

重新加载页面（并没有做任何其他事情）导致：

undefined method `key?' for nil:NilClass

然后重新启动服务器导致启动失败（应用程序崩溃而不启动），并出现以下错误：

这让我觉得有一个兼容性问题btw Rails 3.2.3和acts_as_tree。我不知道如何验证这一点。

我有哪些选择？我不一定需要使用Rails 3.2.3但是如果我降级到3.1.1。（我尝试过）我遇到其他似乎更糟糕的问题（“文件设置”似乎不一样）。

那么，我的选择是什么？你也经历过这个吗？ acts_as_tree有问题，对吧？

看起来从2年前开放

2年前打开此问题不适用于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

如果Rails / ActiveRecord较旧，我们不再支持Ruby 1.8或版本   比3.0。如果您使用的是早于3.0的ActiveRecord版本   请使用0.1.1。

继续前进，我们将尽力支持最新版本的   ActiveRecord和Ruby

这就是为什么他们不打扰那些已经解决的问题

acts_as_tree和rails 3.2.3，不兼容？
