Chỉ mục tìm kiếm trống rỗng sau khi tái lập từ mô hình

Question

Khi tôi cố gắng lập lại các bản ghi từ bên trong một mô hình, nó sẽ kết thúc thiết lập một chỉ mục trống trên máy chủ elasticsearch.

Vì vậy, tôi có một mô hình Course có nhiều Instructors. Bây giờ, tôi có phương thức gọi lại này bên trong mô hình instructor.rb cố gắng reindex bất cứ khi nào một cái gì đó được cập nhật trên Instructor.

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 mô hình trông như thế này:

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 

Hình như gọi Course.search_index.clean_indices trong dòng cuối cùng sẽ làm sạch các chỉ số cũ. Tôi nghĩ rằng bạn có thể muốn gọi nó trong dòng đầu tiên, hoặc không gọi nó cả.

Answer 2

Tôi đã tìm thấy bản sửa lỗi nhanh cho vấn đề này. gọi số touch trên bố mẹ (Course) lớp Instructor và mô hình được liên kết khác dường như đang cập nhật chỉ mục một cách chính xác.

instructor.rb mô hình trông như thế này:

: 
: 
: 
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 

Như móc hoạt động chính xác khi có điều gì xảy ra trên Course mô hình, touch dường như được giải quyết mục đích cho bây giờ.

Trả lời cho vấn đề vẫn còn là một bí ẩn đối với tôi.
