I use Ernie's gem Ransack for searching. When the supporter searches his own tickets (handled by tickets_controller.index) he should also see the unassociated tickets in the search result (views/tickets/index) (in combination with the other serach conditions eg. "date" or something else) (So that he can take an open ticket) expected SQL statement: SELECT * FROM

在Rails2.0当中有大量的用法已经被废弃掉了，在你的应用程序升级到Rails2.0的过程当中必须注意。下面我先列举一下有哪些用法被废弃，然后有什么替代方案，大家请帮我补充： 一、controller的paginate分页方法被拿掉了 2.0以前controller带有paginate这个public的分页方法，现在已经不能使用了。现在推荐的是另外一个替代插件will_paginate，安装这个插件可以用如下的命令： ./script/plugin install svn://errtheblog.com/svn/plugins/will_paginate 关于will_paginate的用法可以参考这个插件里面自带的文档，用法非常简单，或者也可以看作者的博客： http://errtheblog.com/posts/56-im-paginating-again 目前JavaEye2.0的代码也是使用controller的paginate，但是在我们JavaEye3.0代码里面，已经改成了will_paginate。 二、ActionWebServices这个gem包被拿掉了 Rails社区提倡REST，而不是SOAP，如果以前用了SOAP，那么也可以单独安装ActionWebServices，如果是新项目，还是用REST和ActiveResource吧。 三

I've tried this solution: Ruby on Rails: How to sanitize a string for SQL when not using find?
