将分页冲突Rails 3.1.0.rc4

Question

我遇到问题因为与will_paginate gem的错误或冲突而运行我的Rails 3.1.0.rc4应用程序.

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.这似乎是一个已知的问题,很快就会修复:https://github.com/mislav/will_paginate/issues/124

你可以在此期间使用补丁: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"

希望这能回答你的问题.
