モデルからインデックスを再作成した後にSearchkickインデックスが空です

Question

モデル内からレコードを再索引作成しようとすると、elasticsearchサーバー上に空のインデックスを設定してしまいます。

Courseのモデルは、多くの場合、Instructorsです。 今、Instructorで何かが更新されるたびに再インデックスを試みるinstructor.rbモデル内に、このコールバックメソッドがあります。

class Instructor < ActiveRecord::Base 
belongs_to :teacher, :class_name => "User", :foreign_key => "user_id" 
belongs_to :instructorable, polymorphic: true 
after_commit :reindex_course 

private 

    def reindex_course 
    Course.reindex_course 
    end 
end 

course.rbモデルは次のようになります。私はこのクエリを実行すると、新しいインストラクターの作成

class Course < ActiveRecord::Base 
     has_many :instructors, as: :instructorable, dependent: :destroy 

searchkick word_start: [ :name, :description, :instructor_name] 

def search_data 
     { 
     name: name, 
     description: description, 
     searchable: searchable, 
     }.merge(
     instructor_name: instructors.includes(:teacher).pluck(:'users.name').reject(&:nil?), 
     institute_id: creator.try(:institute_id) 
) 
      def self.reindex_course 
       index = Course.reindex(async: true, refresh_interval: "5s") 
       Course.search_index.promote(index[:index_name], update_refresh_interval: true) 
       Course.search_index.clean_indices 
       end 
    end

Answer 1

 def self.reindex_course 
      index = Course.reindex(async: true, refresh_interval: "5s") 
      Course.search_index.promote(index[:index_name], update_refresh_interval: true) 
      Course.search_index.clean_indices 
      end 

は、古いインデックスをきれいになり、最後の行にCourse.search_index.clean_indicesを呼び出すように見えます。私はあなたが最初の行でそれを呼びたいと思うかもしれないと思うか、まったくそれを呼ばないでください。

Answer 2

私はこの問題のクイックフィックスを見つけました。親（Course）のクラスtouchをInstructorと呼び、他の関連モデルはインデックスを正しく更新しているようです。

instructor.rbモデルは次のようになります。何かがCourseモデル上で発生したときフックとして

: 
: 
: 
after_commit :reindex_course 
: 
: 
def reindex_course 
    if self.try(:instructorable).try(:persisted?) 
     if self.instructorable_type == "Course" 
     self.instructorable.touch 
     elsif self.instructorable_type == "ScheduledCourse" 
     self.instructorable.course.touch 
     end 
    end 
    end 

が正常に動作し、touchは今の目的を解決しているようです。

問題は私にとって謎のままです。
