有没有办法创建这样的条件？
- @products = Product.find(:all,:limit => 5,:conditions => { :products => { :locale => 'en',:id NOT '1' },:tags => { :name => ['a','b']})
我想列出所有不包括产品的产品1.
谢谢.

使用squeel宝石.
- Product.where(
- :products => { :locale => 'en',:id.not_in => '1' },'b']}
- ).limit(5)

为此使用AR Extensions.它支持以下条件修饰符：
- * _lt => less than
- * _gt => greater than
- * _lte => less than or equal to
- * _gte => greater than or equal to
- * _ne => not equal to
- * _not => not equal to
现在可以重写您的查询如下：
- @products = Product.find(:all,:joins => [:tags],:conditions => { :locale => 'en',:id_not => '1','b']}
- )
