悲剧和行为

我已经有了一个使用行为作为标签的几个分类法的模型

class Film < ActiveRecord::Base
  attr_accessible :mood_list, :genre_list, :tag_list, :country_list
  acts_as_taggable_on :countries, :genres, :moods, :tags
end

我试图让Ransack搜索找到有任何情绪的记录，并且完全匹配国家。 但它会回退0条记录，而我有匹配的记录，请参阅：

Film.search({:moods_name_in=>['happy', 'snooze']}).result.count => 2    
Film.search({:countries_name_eq=>'USA'}).result.count => 2
Film.search({:moods_name_in=>['happy', 'snooze'], :countries_name_eq=>'USA'}).result.count => 0

它什么都不返回！ 但我绝对有一个：

>> f.countries
[#<ActsAsTaggableOn::Tag id: 13, name: "USA">]
>> f.moods
[#<ActsAsTaggableOn::Tag id: 17, name: "active">, #<ActsAsTaggableOn::Tag id: 16, name: "psyched">, #<ActsAsTaggableOn::Tag id: 15, name: "happy">]
The SQL generated is:
(3.2ms)  SELECT COUNT(DISTINCT "films"."id") FROM "films" LEFT OUTER JOIN "taggings" ON "taggings"."taggable_id" = "films"."id" AND taggings.context = ('moods') AND "taggings"."taggable_type" = 'Film' LEFT OUTER JOIN "tags" ON "tags"."id" = "taggings"."tag_id" LEFT OUTER JOIN "taggings" "country_taggings_films_join" ON "country_taggings_films_join"."taggable_id" = "films"."id" AND taggings.context = ('countries') AND "country_taggings_films_join"."taggable_type" = 'Film' LEFT OUTER JOIN "tags" "countries_films" ON "countries_films"."id" = "country_taggings_films_join"."tag_id" WHERE (("tags"."name" IN ('happy', 'snooze') AND "countries_films"."name" = 'USA'))

请任何帮助！

更新：2013年1月11日问题应该在于正确应用搜索谓词。 有几个实际上没有解决的相关问题。 Rails，Ransack：如何搜索HABTM关系中的“全部”匹配而不是“任何”

将ActiveRecord habtm查询转换为Arel

更新看起来问题是has_and_belongs_to_many https://github.com/ernie/ransack/issues/164无法解析的事件

你可以通过关联添加它，fe： class Person < ActiveRecord::Base PERSON_SEARCH_OPTIONS = :name_or_email_or_tags_name_cont end它适用于我

我认为这是更好的方法。
