Question

我刚刚安装了searchlogic gem，但是当我尝试通过控制台访问基本方法时，我收到以下错误：

>> User.username_not_null
NoMethodError: undefined method `username_not_null' for #<Class:0x1033a1d90>
    from /Library/Ruby/Gems/1.8/gems/searchlogic-2.4.27/lib/searchlogic/named_scopes/conditions.rb:81:in `method_missing'
    from /Library/Ruby/Gems/1.8/gems/searchlogic-2.4.27/lib/searchlogic/named_scopes/association_conditions.rb:19:in `method_missing'
    from /Library/Ruby/Gems/1.8/gems/searchlogic-2.4.27/lib/searchlogic/named_scopes/association_ordering.rb:27:in `method_missing'
    from /Library/Ruby/Gems/1.8/gems/searchlogic-2.4.27/lib/searchlogic/named_scopes/ordering.rb:30:in `method_missing'
    from /Library/Ruby/Gems/1.8/gems/searchlogic-2.4.27/lib/searchlogic/named_scopes/or_conditions.rb:28:in `method_missing'
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1959:in `method_missing'
    from (irb):1

我仍然掌握宝石，这常常让我陷入困境 - 有人能指出我正确的方向来解决这个问题吗？

不要将Searchlogic用于您可以使用Rails的内容：

 User.all(:conditions => ["username IS NOT NULL"])

Searchlogic安装了gem，但我无法访问方法
