Ruby on rails 如何使用rake任务和数据库清理器gem在rubyonrails中填充和清理数据库？

我在一个文件中有两个rake任务。播种和繁殖。 seed正在创建必要的数据，而populate正在为我的测试填充样本数据

在我的测试中，我正在操作一个数据库（添加新条目、删除它等等）。我正在使用Database cleaner gem重置数据库，但是当我重置数据库时，我需要为下一个测试填充数据。我有以下设置，但它不工作，数据库仍然是空的，填充数据不存在

这是spec/support/database_cleaner.rb

require 'rake'
load File.expand_path("../../../lib/tasks/my_tasks.rake", __FILE__)
RSpec.configure do |config|
  config.use_transactional_fixtures = false 
  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
  end
  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end
  config.before(:each, :js => true) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
    DatabaseCleaner.start
    Rake::Task.define_task(:environment)
    Rake::Task['db:seed'].invoke
    Rake::Task['db:populate'].invoke
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
end

等级库/rails\u helper.rb

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV['RAILS_ENV'] ||= 'test'
require 'rake'

require File.expand_path('../../config/environment', __FILE__)
# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?
 require 'spec_helper'
 require 'factory_girl_rails'
 require 'rspec/rails'
 require 'capybara/poltergeist'

 # Checks for pending migrations before tests are run.
 # If you are not using ActiveRecord, you can remove this line.
 ActiveRecord::Migration.maintain_test_schema!

 Capybara.configure do |config|
   config.default_wait_time = 20
 end

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

 config.include FactoryGirl::Syntax::Methods

 # 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.infer_spec_type_from_file_location!
end

我找到了一个解决办法，但这不是完美的，我仍然在寻找解决办法，所以请张贴一个答案，如果你找到它。我不会选择这个作为正确答案

您需要将content spec/support/database_cleaner.rb文件放入spec/spec_helper.rb文件中

RSpec.configure do |config| 
.
.
.
  config.use_transactional_fixtures = false 
  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  config.before(:each, :js => true) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
    DatabaseCleaner.start
    Rake::Task.define_task(:environment)
    Rake::Task['db:seed'].invoke
    Rake::Task['db:populate'].invoke
  end

  config.after(:each) do
    # DatabaseCleaner.clean
  end
  config.infer_spec_type_from_file_location!
end
