Ruby on rails Rails 5.2中的ActiveRecord:save/update不保存记录，即使它说保存了

在ruby 2.6.5、postgres 10.11和pg gem 1.1.4版的Rails 5.2.4.1应用程序中，我有一个如下的ActiveRecord模型：

class房地产{select（RealEstate.column_names.map！（&:to_sym）-[：metadata]）
作用域：活动，->{where（活动：true）}
有_many:lots，->{where（lot:true）}，类名：'realstate'，外键：'program\u id'
属于：程序，类名：'realstate'，可选：true
枚举旧的或新的：{
老:0,，
新#U大厦：1#开发商新房地产项目
}
枚举事务类型：{
租金:0,，
购买：1
}
枚举属性\u类别：{
公寓：0，
众议院：1，
其他：2
}
结束

db/structure.sql

中的底层数据模型如下（某些列匿名）：

正如您所看到的，没有Rails回调。“奇怪之处”——我们使用一个postgres JSONB列和一个postgres integer数组列

现在我们有了一个管理员更新路径来编辑其中的一些记录。它不遵循命名约定，也不使用活动记录验证，而是使用干式验证：

require 'dry-validation'

module Admin
  class NewRealEstatesController < Admin::BaseController
    before_action :set_form, only: [:edit, :update]

    def update
      validation_result = AdminRealEstateSchema.call(real_estate_listing_params.to_h)
      if validation_result.success?
        # Don't mind column mappings with the dry schema validator, there might be inconsistencies
       # because I anonymized the column names, but the mapping is correct and validations pass
        @estate.some_string_1 =  params[:real_estate][:some_string_1]
        @estate.some_string_2 = params[:real_estate][:some_string_2]
        @estate.some_string_3 = params[:real_estate][:some_string_3]
        @estate.property_category = params[:real_estate][:property_category]
        @estate.some_string_4 = params[:real_estate][:some_string_4]
        @estate.price = params[:real_estate][:price]
        @estate.some_string_5 = params[:real_estate][:some_string_5]
        @estate.active = params[:real_estate][:active]
        @estate.some_timestamp_1 = params[:real_estate][:some_timestamp_1]
        @estate.some_timestamp_2 = params[:real_estate][:some_timestamp_2]
        @estate.some_count = params[:real_estate][:some_count]
        @estate.surface = params[:real_estate][:surface]
        @estate.some_boolean_1 = params[:real_estate][:some_boolean_1]
        @estate.some_boolean_2 = params[:real_estate][:some_boolean_2]
        res = @estate.save
        render json: { result: 'done', debug: { res_save_ar: res, changed: @estate.saved_changes?, \
          changes: @estate.saved_changes, previous_changes: @estate.previous_changes } }, status: 200
      else
        respond_to do |format|
          format.html { render :edit }
          format.json { render json: { errors: validation_result.errors.map{|key, error| "#{key} : #{error[0]}"} },  \
            status: :unprocessable_entity, serializer: nil }
        end
      end
    end

    def edit; end

    private 

    def set_form
      @estate = RealEstate.find(params[:id])
    end

    def real_estate_listing_params
      params[:real_estate_listing].permit(...) # all strong params edited in route, it's correct
    end
  end
end

AdminRealEstateSchema = Dry::Validation.Form do
  configure { config.type_specs = true, config.messages = :i18n }
  PROPERTY_CATEGORIES = %w(house apartment other)
  required(:property_category, :string).filled(:str?, included_in?: PROPERTY_CATEGORIES)
  required(:some_string_1, :string).filled(:str?)
  required(:some_string_2, :string).filled
  optional(:some_string_3).maybe(:str?)
  optional(:some_string_4).maybe(:str?)
  optional(:some_string_4).maybe(:str?)

要求“干式验证”
模块管理员
类NewRealEstatesController

视图是正确的，使用

remote:true

现在谈谈这个问题：有时，由于表单的存在，记录会被保存和更新，但没有一致性，有时绝对不会保存和更新，就像更改已被回滚一样，即使

save

返回true，如web控制台中返回的JSON所示

ActiveRecord还可以正确地映射所有应使用正确值更新/保存的列，如

@estate.saved\u changes

Rspec测试全部通过。但只有在生产中，我们才会遇到这种错误

现在需要注意的几点可能很重要：

• 几个月前，我们已经遇到了一个

  create\u或
  bug。无法正确创建记录。迫于最后期限，我通过
  ActiveRecord:：Base.connection.execute
  求助于原始SQL，结果一切正常

• 此表非常活跃，有许多后台作业插入/读取客户的数据
• 此表上没有自定义postgres触发器

我越来越绝望了，我想这可能是我们代码中的一个bug（很明显），或者是

activerecord

中的一个bug

有什么想法吗

我相信这可能与最新稳定版本中的一个已知错误有关。我会和其他一些与pg开放相关的问题一起检查。我在使用pg数据类型时遇到了类似的情况，这些数据类型不是rails默认的int和string值（使用JSONB和Money）。我们是n
