将分页冲突 Rails 3.1.0.rc4

Question

由于错误或与 will_paginate gem 冲突，我在运行 Rails 3.1.0.rc4 应用程序时遇到问题。

当我尝试启动服务器时产生的错误如下：

我遇到了同样的问题。看来这是一个已知问题，很快就会得到解决： https://github.com/mislav /will_paginate/issues/124

您可以同时使用补丁：https://github.com/p7r/will_paginate/commit/53d1da6da003dc172ee054e4cc416d0723f00b88

或者，更好的是，在 Gemfile 中使用以下行：

gem "will_paginate", :git => "https://github.com/p7r/will_paginate.git", :branch => "rails3"

希望这能回答您的问题。
