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來處理早期版本的Rails 3（比如3.1.1）的一些不同的項目，但沒有任何問題，但對於這個版本根本不起作用。如果是因爲3.2.3或其他我使用的東西，我還沒有能夠確認。acts_as_tree和rails 3.2.3不兼容？

這是我已經試過了，沒有用： - 對幾個不同的控制器使用acts_as_tree - 只有使用acts_as_tree（沒有order語句） - 運行包安裝包更新 - 仔細檢查PARENT_ID存在，是整數

首先，當我嘗試這樣做，在我第一次嘗試了：

undefined method `acts_as_tree'

重新加載頁面（而不是做別的）引起的：

undefined method `key?' for nil:NilClass

然後重新啓動服務器造成發射失敗（應用程序會崩潰和無法啓動），出現以下錯誤：

這讓我想有一個保持兼容問題BTW的Rails 3.2.3和acts_as_tree。我不知道如何驗證這一點。

我有什麼選擇？我不一定需要使用Rails 3.2.3，但是如果我降級到3.1.1。（我試過）我遇到了其他更糟糕的問題（「文件設置」似乎不一樣）。

那麼，我有什麼選擇？你有沒有體驗過這個？ acts_as_tree有問題，對嗎？

貌似有一個從2年前開放

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

選項

acts_as_tree_rails3 gem install acts_as_tree_rails3

或

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

Ë DIT：

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

與評論

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

這就是爲什麼他們不使用acts_as_tree_rails3的伎倆那些打開的問題

打擾。我看不出你所鏈接的問題是如何相關的。從未聽說過acts_as_tree_rails3，並且不需要將其用於3.1.1。但我很高興它的工作。謝謝！ – Christoffer

謝謝它適合我。 –
