如何通过属性来处理相关对象？

我有一个 Ruby on Rails 模型，其中有很多 HABTM 关系。本质上，我正在为客户制作一个以滑板为主题的视频共享网站。每个视频通过 HABTM 都有许多属性：位置、滑板者、标签、位置、音乐、设备、地点、区域等...并且它还有一些重要的类属性：标题、描述等

...我的客户希望每个视频播放器使用所有前面提到的描述性数据提供“相关视频”提要。此外，信息应该被加权（相似的标题优先于相似的标签）。

我试图找到一种实现 Google SiteSearch 来处理繁重工作的好方法，但找不到好的搜索词语法，即：

inurl: example.com/videos related:example.com/videos/4638872

不幸的是，这实际上不起作用......

I have a Ruby on Rails model that has quite a few HABTM relationships. Essentially, i'm making a video sharing site themed around skateboarding for a client. Each video has many attirbutes through HABTM: Location, Skateboarders, tags, location, music, equipment, spot, region, etc... And it also has a few class attributes that are significant: Title, description, etc...

The idea here is my client would like a "Related Videos" feed by each video player, using all of the formerly mentioned descriptive data. Furthermore, the information should be weighted (similar titles take precedence over similar tags).

I was trying to find a good way implement Google SiteSearch to handle the grunt work, but can't find a good search term syntax ie:

inurl: example.com/videos related:example.com/videos/4638872

Which doesn't actually work, unfortunately...

那么，您正在寻找一个搜索词来查找您的视频吗？我不太确定这个问题，但如果是这样，这对你有用吗？

site:example.com inurl:videos

So, you are looking for a search term to use in order to locate your videos ? I'm not so sure about the question, but if so, would this work for you ?

site:example.com inurl:videos

通过使用 ferret 进行关键字爆炸搜索解决了这个问题。

def related
    string = self.name + " " + self.tag_name + " " + self.skateboarder_name + " " + self.category_name + " " + self.editor_name
    #probably could have used "join" there...
    s = "*" + string.gsub(" ", "* OR *") + "*"
    relates = Video.find_with_ferret(s)
    #takes out duplicates and gices 10 to choose from
    while relates.count <= 10
        relates << Video.random
        relates = relates.uniq
    end
    #take out original video
    relates = relates - [Video.find(self.id)]
    #send back with "middle data"... for some reason i thought this might be more accurate....
    return relates[1..8]
end

Solved this by using ferret to do a keyword explode search.

def related
    string = self.name + " " + self.tag_name + " " + self.skateboarder_name + " " + self.category_name + " " + self.editor_name
    #probably could have used "join" there...
    s = "*" + string.gsub(" ", "* OR *") + "*"
    relates = Video.find_with_ferret(s)
    #takes out duplicates and gices 10 to choose from
    while relates.count <= 10
        relates << Video.random
        relates = relates.uniq
    end
    #take out original video
    relates = relates - [Video.find(self.id)]
    #send back with "middle data"... for some reason i thought this might be more accurate....
    return relates[1..8]
end
