Ruby-on-rails gem 因“where”而失败meta_where 的条件
我有一个问题，可能是宝石问题，但可能是元问题。我使用gems安装meta_where-1.0.4，响应是我成功了，并且提供了meta_where的uri，但是当我在控制器的搜索方法中尝试where-条件时，类似于这个例子，meta-where提供：
Person.where(:skill_set.matches => 'Hello%'
报告错误：
"undefined method 'matches' for :skill_set:Symbol"
就好像宝石的方法没有被访问一样。我尝试使用“require”，但这没有帮助。
我使用的是 Windows XP、Firefox、Ruby 1.9.2。
我需要做什么？ 谢谢，巴尼
I have a question about what is probably a gems problem, but may be meta-where. I used gems to install meta_where-1.0.4, and the response was that I succeeded and the uri for meta_where was provided, but when I tried a where-condition in the search method of a controller, similar to this example that meta-where provides:
Person.where(:skill_set.matches => 'Hello%'
an error was reported:
"undefined method 'matches' for :skill_set:Symbol"
It's as if the gem's methods aren't being accessed. I tried using "require" but that didn't help.
I'm using Windows XP, Firefox, Ruby 1.9.2.
What do I need to do?
Thanks, Barney

我假设您已经运行了迁移，并且
person表中有一个skill_set属性：您不需要require。只需将'gem meta_where'添加到您的 Gemfile 中，然后运行 'bundle install'即可。I assume you have run the migrations and there is a
skill_setattribute in thepersontable: you don't needrequire. Just add'gem meta_where'to your Gemfile and then run'bundle install'.
