Ransack和act-as-taggable-on问题

Question

我有一个使用act-as-taggable-on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搜索找到有任何心情和完全匹配国家的记录.但它返回了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

它什么都没有!但我肯定有一个:

>> 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'))

请帮忙!

更新:2013年1月11日问题应该在于正确应用ransack谓词.有几个相关问题实际上没有解决. Rails,Ransack:如何在"所有"匹配中搜索HABTM关系而不是"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无法解决的事件

Answer 1

您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 它对我有用

我认为这是更好的方法。
