Ruby on rails RubyonRails测试-ActiveRecord:：RecordNotUnique:PG:：UniqueViolation:ERROR:重复键值违反了唯一约束；xxx_xxxx_xxxx_pkey“；

我有以下型号。我正在使用Rails 6.0.3.2（Ruby 2.7.1p83）并使用Minitest作为测试引擎

class AuthContentType < ApplicationRecord
  has_many :auth_permissions
end

我可以得到帮助吗？我一直在尝试执行一些建议的解决方案。但这对我没有帮助

解决方案：1（在控制台中运行）

我的测试/测试助手.rb

ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'

class ActiveSupport::TestCase
  # Run tests in parallel with specified workers
  parallelize(workers: :number_of_processors, with: :threads)

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...

end

ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'

class ActiveSupport::TestCase
  # Run tests in parallel with specified workers
  # parallelize(workers: :number_of_processors, with: :threads)

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...

end

数据库中可能有唯一的索引。您可以添加一个任务并运行

rake数据库：更正顺序id

rails g任务数据库更正\u seq\u id

然后生成一个文件，如lib/tasks/database.rake

你应该把这个街区：

namespace :database do
    desc "Correction of sequences id"
    task correction_seq_id: :environment do
        ActiveRecord::Base.connection.tables.each do |t|
            ActiveRecord::Base.connection.reset_pk_sequence!(t)
        end
    end
end

知道我的机器有Windows操作系统，我通过执行以下操作解决了问题：

我把这句话注释掉了

parallelize(workers: :number_of_processors, with: :threads)

从我的test_helper.rb

ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'

class ActiveSupport::TestCase
  # Run tests in parallel with specified workers
  parallelize(workers: :number_of_processors, with: :threads)

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...

end

ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'

class ActiveSupport::TestCase
  # Run tests in parallel with specified workers
  # parallelize(workers: :number_of_processors, with: :threads)

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...

该错误表明，从加载测试装置时，您违反了表auth\u content\u types上的主键约束。通过从设备标签构建校验和，设备使用稳定的ID。您可能多次加载装置，或者清理不起作用。请发布您的

lib/test\u helper.rb

和

test/controllers/gd\u controller\u test.rb

，他们需要找到错误的确切来源。我添加了“test\u helper.rb”和test/controllers/gd\u controller\u test.rb脚本here@Gizemsoylutr回溯显示问题发生在加载测试夹具时，具有稳定（固定）ID的。加载夹具后，rails已经重置了PK序列以避免冲突：Windows上应该支持并行测试，并且由于rails应该为每个工作者创建不同的测试数据库，因此不应该有任何冲突。也许这是一个并行测试的bug，只发生在windows上。您可以尝试在rails问题跟踪程序中报告问题：

ENV['RAILS_ENV'] ||= 'test'
require_relative '../config/environment'
require 'rails/test_help'

class ActiveSupport::TestCase
  # Run tests in parallel with specified workers
  # parallelize(workers: :number_of_processors, with: :threads)

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
