在Rails 4.0.0.rc1中無法檢測到association_proxy.rb

我正在使用composite_primary_keys gem與Rails 4.0.0.rc1。增加的Gemfile在Rails 4.0.0.rc1中無法檢測到association_proxy.rb

gem 'composite_primary_keys'

和運行包安裝後，我加

require 'composite_primary_keys'

到application.rb。然而，當我運行rails generate create_table，我得到了以下錯誤：

/Users/name/.rvm/gems/ruby-1.9.3-p385/gems/activesupport-4.0.0.rc1/lib/active_support/dependencies.rb:228:in `require':

我檢查composite_primary_keys.rb文件中的這種寶石，並發現它需要association_proxy.rb。但是，Rails似乎找不到這個文件。

對於Rails的加載順序，我是否在錯誤的時間需要這個gem？或者這是因爲association_proxy.rb不再在Rails 4中？

有同樣的問題，使用

gem 'composite_primary_keys', '=3.1.0'

的差異通過刮擦版本，並

bundle update composite_primary_keys

嘗試不同的版本可能會幫助固定它。

是的。版本3.1.0不起作用。已更新至6.0.0。 – rishabhmhjn
