【问题描述】：

目前正在尝试使用 capybara/rspec/factory girl 测试多个数据库，尽管我的数据库清除存在问题。

查询错误：

': Mysql2::Error: Duplicate entry '1503' for key 'PRIMARY': INSERT INTO `users`

Facility_spec.rb

feature "User with facilities" do
  @current_user = FactoryGirl.create(:user_with_facility)   
  scenario 'A user can perform a walk-through', :js => true do
    login_as
    visit '/'
    expect(page).to have_text "Our records indicate that you have access to 1 facilities:"
    ...
  end

  @current_user = FactoryGirl.create(:user_with_facility)   
  scenario 'The quick-form requires first_name, last_name, and dob', :js => true do
    login_as
    visit '/'
    expect(page).to have_text "Our records indicate that you have access to 1 facilities:"
    ...
  end
end

rails_helper.rb

cleaner = DatabaseCleaner[:active_record,{:connection => :emp_portal_test}]
rt_cleaner = DatabaseCleaner[:active_record, {connection: :test_rt_treats}]

RSpec.configure do |config|
 config.include Capybara::DSL
 config.include FactoryGirl::Syntax::Methods

 config.use_transactional_fixtures = false

 config.before(:suite) do 
   cleaner.strategy = :truncation
   rt_cleaner.strategy = :truncation     
 end

 config.before(:each) do 
   cleaner.strategy = :truncation
   rt_cleaner.strategy = :truncation
   cleaner.start
   rt_cleaner.start
 end

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

config.after(:each) do 
  cleaner.clean
  rt_cleaner.clean   
end

user_factory.rb

FactoryGirl.define do
 factory :user do
  id 33065
  first_name "Andrew"
  last_name  "Larson"
  select_id "al44096"
    factory :user_with_facility do
      after(:create) do |user|
        user.facility_assignments << create(:facility)
      end
    end
  end

factory :facility do
    id 1550
    ref_select_id 1550
    status -1
    name "St. Paul's Home & Apartments"
    name_internal "St Paul's Home"
    dept_id "R51"
    ...
end

当我在这个测试环境中创建一个新患者时，它会在我下次使用之前被擦除，尽管我不能在我的代码中使用相同的 current_user。

【问题讨论】：

您如何管理多个数据库连接？您是为此使用 gem 还是手动操作？
不完全确定您所说的“管理”是什么意思。我有 cleaner = DatabaseCleaner[:active_record,{:connection => :emp_portal_test}] rt_cleaner = DatabaseCleaner[:active_record, {connection: :test_rt_treats}] 每个都与数据库建立连接以执行清理任务。

【解决方案1】：

好吧，几块……

我的一个数据库表没有自动增量功能，因为它的 id 是个问题，所以我通过 ... 向表添加了自动增量功能。
```
ALTER TABLE document MODIFY COLUMN document_id INT auto_increment
```
解决此问题后，我的数据库清理器工作正常。

奖励：我不知道，但是在我需要的两个场景中访问 @current_user

background do
  @current_user = FactoryGirl.create(:user_with_facility)   
end

直到现在我才看到这个，很棒。
```
2 examples, 0 failures
```
