Rspec 加载旧架构

Question

我正在处理一个遗留项目（最近从 rails 4.1 升级到 5.2），我不得不更改关联表。之前：报表有很多客户，客户有很多报表。现在我创建了一个ClientsReport表，它不仅包含 client_id 和 reports_id，而且还有一个idasprimary_key和一个can_manage（布尔值）。

与当调用rspec的它给我一个错误的测试reports_clients.for(report).first.can_manage 说unKnownAttribute can_manage的<ClientsReport client_id: 1, report_id:3> 任何迹象，如果id也没有can_manage

所以看起来它正在使用旧模式。

还尝试ActiveRecord::Migration.maintain_test_schema!按照此处的建议添加，但我不确定

我尝试运行，rake:db:prepare但它给我带来了一堆错误，现在看起来我破坏了测试数据库，因为我有 4 个失败的测试，现在我有 166 个......

我的 spec_helper.rb 看起来像这样：

Spork.prefork do
  require 'simplecov'
  SimpleCov.start 'rails'
  # This file is copied to spec/ when you run 'rails generate rspec:install'
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'devise'
  require './spec/controllers/controller_helpers.rb'

  # Requires supporting ruby files with custom matchers and macros, etc,
  # in spec/support/ and its subdirectories.
  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    config.include Devise::Test::ControllerHelpers, type: :controller
    config.include ControllerHelpers, type: :controller

    config.include Capybara::DSL

    # ## Mock Framework
    #
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
    #
    # config.mock_with :mocha
    # config.mock_with :flexmock
    # config.mock_with :rr

    # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    # If you're not using ActiveRecord, or you'd prefer not to run each of your
    # examples within a transaction, remove the following line or assign false
    # instead of true.
    config.use_transactional_fixtures = true

    # If true, the base class of anonymous controllers will be inferred
    # automatically. This will be the default behavior in future versions of
    # rspec-rails.
    config.infer_base_class_for_anonymous_controllers = false

    config.infer_spec_type_from_file_location!

    # Run specs in random order to surface order dependencies. If you find an
    # order dependency and want to debug it, you can fix the order by providing
    # the seed, which is printed after each run.
    #     --seed 1234
    config.order = "random"
    config.include FactoryGirl::Syntax::Methods
  end

end


Spork.each_run do
  # This code will be run each time you run your specs.
end

在确保您的架构是最新的后，您可以使用此命令完全重置测试数据库。

bin/rails db:environment:set db:drop db:create db:schema:load RAILS_ENV=test
