Bir nesnenin sanal niteliğini pg_search ile nasıl arayabilirim?

Question

Üzerinde kurulum acts_as_taggable sahip bir sınıf Node var, bu yüzden herhangi bir düğüme user_tags ekleyebilir. Ayrıca, user_tag_list'daki tüm kullanıcılar için gerçek User kayıtlarına bakacak olan Node modelimde de bir yöntemim var. Node.id = 85 ilk ada sahip bir kullanıcı etiketi vardır çünkü

[32] pry(main)> m = Node.find(85) 
    Node Load (8.6ms) SELECT "nodes".* FROM "nodes" WHERE "nodes"."id" = $1 LIMIT 1 [["id", 85]] 
=> #<Node id: 85, name: "House Fire 2", family_tree_id: 57, user_id: 57, media_id: 228, media_type: "Video", created_at: "2015-05-15 00:20:26", updated_at: "2015-05-20 01:06:34"> 
[33] pry(main)> m.user_tags 
    ActsAsTaggableOn::Tag Load (3.8ms) SELECT "tags".* FROM "tags" INNER JOIN "taggings" ON "tags"."id" = "taggings"."tag_id" WHERE "taggings"."taggable_id" = $1 AND "taggings"."taggable_type" = $2 AND "taggings"."context" = 'user_tags' [["taggable_id", 85], ["taggable_type", "Node"]] 
=> [#<ActsAsTaggableOn::Tag id: 4, name: "gerry@test.com", taggings_count: 1>, #<ActsAsTaggableOn::Tag id: 6, name: "danny@test.com", taggings_count: 1>] 
[34] pry(main)> m.user_tag_list 
    ActsAsTaggableOn::Tag Load (0.8ms) SELECT "tags".* FROM "tags" INNER JOIN "taggings" ON "tags"."id" = "taggings"."tag_id" WHERE "taggings"."taggable_id" = $1 AND "taggings"."taggable_type" = $2 AND (taggings.context = 'user_tags' AND taggings.tagger_id IS NULL) [["taggable_id", 85], ["taggable_type", "Node"]] 
=> ["gerry@test.com", "danny@test.com"] 
[35] pry(main)> m.tagged_users 
    User Load (5.7ms) SELECT "users".* FROM "users" WHERE "users"."email" = 'gerry@test.com' LIMIT 1 
    User Load (2.1ms) SELECT "users".* FROM "users" WHERE "users"."email" = 'danny@test.com' LIMIT 1 
=> [#<User id: 52, email: "gerry@test.com", encrypted_password: "$2a$10$KaX1kvtIw1.jGITnt9Czqeq3xTzhY3OM052NSHsL5Lf...", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 5, current_sign_in_at: "2015-04-03 17:10:28", last_sign_in_at: "2015-04-03 00:38:24", current_sign_in_ip: "127.0.0.1", last_sign_in_ip: "127.0.0.1", created_at: "2015-03-05 01:36:31", updated_at: "2015-04-03 17:10:28", first_name: "Gerry ", confirmation_token: nil, confirmed_at: "2015-03-05 01:36:52", confirmation_sent_at: nil, unconfirmed_email: nil, invitation_relation: "uncle", avatar: nil, invitation_token: nil, invitation_created_at: "2015-03-05 01:36:31", invitation_sent_at: "2015-03-05 01:36:31", invitation_accepted_at: "2015-03-05 01:36:52", invitation_limit: nil, invited_by_id: 1, invited_by_type: "User", invitations_count: 0, bio: nil, last_name: "Atrick", gender: 0>, 
#<User id: 58, email: "danny@test.com", encrypted_password: "$2a$10$ZpzLH17iFrOXzH4U/pOX.e4nwN.9IJ1s1Ap/zQglk9K...", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 6, current_sign_in_at: "2015-05-26 04:36:32", last_sign_in_at: "2015-04-03 00:14:55", current_sign_in_ip: "127.0.0.1", last_sign_in_ip: "127.0.0.1", created_at: "2015-03-12 03:39:28", updated_at: "2015-05-26 04:36:32", first_name: "Daniel", confirmation_token: nil, confirmed_at: "2015-03-12 05:46:18", confirmation_sent_at: nil, unconfirmed_email: nil, invitation_relation: "son", avatar: nil, invitation_token: nil, invitation_created_at: "2015-03-12 03:39:28", invitation_sent_at: "2015-03-12 03:39:28", invitation_accepted_at: "2015-03-12 05:46:18", invitation_limit: nil, invited_by_id: 57, invited_by_type: "User", invitations_count: 0, bio: nil, last_name: "Marty", gender: 0>] 

Yani, ideal olarak, ne yapmak istiyorsunuz kullanıcıların Gerry diyelim aramak için ve yukarıdaki örnekten Node.id = 85 döneceğini izin olduğunu: İşte bir resimdir Gerry.

Bu benim mevcut pg_searchNode tarih:

pg_search_scope :node_search, against: [:name, :user_id, :circa], 
    using: { tsearch: { any_word: true} }, 
    :associated_against => { 
     comments: [:message], 
     user: [:first_name, :last_name, :email], 
     memberships: [:relation] 
    } 

Ben pg_search dinamik kapsamını kullanmak mümkün olmalıdır gibi hissediyorum, ben ona pek grok olamaz.

Bu nasıl elde ki?

Answer 1

Cevabın oldukça düz ileri olduğu ortaya çıktı. Ben

include PgSearch 
    pg_search_scope :node_search, against: [:name, :user_id, :circa], 
    using: { tsearch: { any_word: true, dictionary: :english} }, 
    :associated_against => { 
     comments: [:message], 
     user: [:first_name, :last_name, :email], 
     memberships: [:relation], 
     user_tags: [:name] 
    } 

Not:

acts_as_taggable_on :user_tags 

çözüm şöyle pg_search bildiriminde bu sütunu eklemek için basitçe:

bu benim Node modelinde acts-as-taggable-on beyanı olduğunu düşünürsek alanı user_tags içinde belirtmek için (yani :name özniteliği).

Yani şimdi, bunu isteyerek :user_tags gibi o sanal özniteliği karşı arar.
