Ruby on rails RubyonRails回调不'；我不在Heroku工作，但在本地工作

我一直在使用rails\u admin开发一个学校应用程序。本地的一切都很好，但是当我推到Heroku时，我在模型中定义的回调没有被使用，甚至不是最简单的回调。所以我来问你，是否有人以前遇到过类似的问题，或者可以帮助我解释我的日志，因为我找不到原因

首先，我的Gemfile是这样的：

source 'https://rubygems.org'

ruby '2.2.0'

group :development, :test do
    gem 'railroady'
end

# For documenting models automatically
gem 'annotate', '~> 2.6.6'

# For styling all HTML using SASS
gem 'bourbon'
gem 'neat'
gem 'bitters'

# For using creating SQL triggers inside models
gem 'hairtrigger'

# For creating seed data files from existing data in the database
gem 'seed_dump'

# Used for translations of the mailer and account confirmations
gem 'devise-i18n'

# User permissions and login
gem 'devise'
gem 'cancancan', '~> 1.10'
gem "rolify"
gem "figaro"
gem "rails_admin"

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.1'
# Use sqlite3 as the database for Active Record on the development environment
gem 'sqlite3', group: :development
# Use PostgreSQL as the database for Active Record on the production environment
gem 'pg', group: :production
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer',  platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder

# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0',          group: :doc

# Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
gem 'spring', group: :development
gem 'rails_12factor', group: :production

这是我在中使用回调的模型：

region.rb 这就是我在本地服务器上执行相同操作时看到的，正如您所看到的，在POST块中，“key”元素显然是insert查询的参数

我发现了错误！它与开发早期在Heroku上的PostgreSQL数据库上直接创建的团队中的其他人的SQL触发器有关，因为它与回调同时被调用，一旦我删除了它，一切都开始按预期工作。

只要生产和本地之间存在差异，我就从基础开始：尝试在Heroku上重新启动应用程序，如果没有差异，请在回调中添加调试语句以查看是否命中：

logger.info“内部回调”

并重新部署。确保两个站点中的代码相同，等等。您在两个环境中使用的数据库是否相同？不，我使用sqlite3进行开发，使用PostgreSQL进行生产，并且我尝试在heroku上重新启动应用程序，但没有成功。不过，我已经解决了这个问题，请看下面的答案。你能再解释一下吗？我现在有这个问题。
