延迟作业仅在heroku上失败

Question

我有一个在本地运行的简单工作（在开发和生产以及暂存中）但在heroku（生产和暂存）上失败。

命令是DoctorLocation.reindex!，这是一种用于algolia的方法。

引发的错误是NameError: uninitialized constant DoctorProfile::Recommendation：

app[worker.1]: [Worker(host:c304ffd7-6c21-4eeb-b423-d42fae5d2adb pid:4)] Job DoctorLocation.reindex! (id=70) FAILED (3 prior attempts) with NameError: uninitialized constant DoctorProfile::Recommendation

奇怪的是DoctorLocation.reindex!能够在控制台中成功运行，只有在使用延迟的作业时它才会失败。

另请注意，DoctorProfile和Recommendation是两个独立的模型，这使得此错误更加混乱。

更新：医生位置模型的代码：

class DoctorLocation < ApplicationRecord
  include AlgoliaSearch
  include AlgoliaDelayedJob

  belongs_to :doctor_profile
  belongs_to :location

  delegate :first_name, :last_name, :name, :photo_url, :gender, :practice, to: :doctor_profile

  unless Rails.env.test?
    algoliasearch :per_environment => true, if: :approved?,
                  id: :uuid, enqueue: :trigger_delayed_job do
      attribute :id, :uuid, :first_name, :last_name, :name, :photo_url, :gender,
                :practice, :location
      attribute :doctor_id do
        doctor_profile.id
      end

      attribute :patients do
        doctor_profile.patients.map{|x| {
          uuid: x.uuid, photo_url: x.photo_url, first_name: x.first_name,
          last_name: x.last_name, name: x.name, id: x.id
        }}
      end
      attribute :reviews do
        doctor_profile.reviews.map{|x| {
          body: x.body,

          patient_profile_uuid: x.patient_profile.uuid,
          patient_profile_id: x.patient_profile.id,
          patient_profile_name: x.patient_profile.name
        }}
      end
      attribute :patient_count do
        doctor_profile.patients.length
      end
      attribute :patient_ids do
        doctor_profile.patients.map(&:uuid)
      end
      attribute :insurances do
        doctor_profile.insurance_providers.map{|x| "#{x.category}:#{x.name}"}
      end
      attribute :specialties do
        doctor_profile.specialties.map(&:name)
      end
      geoloc :lat, :lon

      tags do
        doctor_profile.specialties.map(&:name)
      end

      attribute :group_ids do
        doctor_profile.patients.map{|x| x.group_ids }.flatten.compact.uniq

      attribute :liked_by_friends_of_user_id do

      end

      attributesToIndex ['first_name', 'last_name', 'name']
      attributesForFaceting [
        :insurances, :gender, :patient_ids, :liked_by_friends_of_user_id,
        :group_ids
      ]
      customRanking ['desc(patient_count)']
    end
  end

AlgoliaDelayedJob

module AlgoliaDelayedJob
  extend ActiveSupport::Concern

  module ClassMethods
    def trigger_delayed_job(record, remove)
      if remove
        # record not saved, so delete from index by id
        # (can't instantiate the model and call .delay.remove_from_index!)
        index = Algolia::Index.new("#{self.name}_#{Rails.env}")
        index.delete_object(record.uuid)
      else
        obj = self.find(record.id)
        obj.index!
      end
    end
  end
