Ruby on rails 4 数据库清理器正在清除我的开发数据库

我已经为rails 4应用程序配置了

数据库清理器

， 每次运行测试时，我都发现我的数据库在

test

和

development

环境中都被删除了

我的配置在

rails\u helper

中，如下所示：

ENV["RAILS_ENV"] ||= 'test'
# This file is copied to spec/ when you run 'rails generate rspec:install'
require 'spec_helper'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'database_cleaner'
Rails.env = "test"
# Add additional requires below this line. Rails is not loaded until this point!

# Requires supporting ruby files with custom matchers and macros, etc, in
# spec/support/ and its subdirectories. Files matching `spec/**/*_spec.rb` are
# run as spec files by default. This means that files in spec/support that end
# in _spec.rb will both be required and run as specs, causing the specs to be
# run twice. It is recommended that you do not name files matching this glob to
# end with _spec.rb. You can configure this pattern with the --pattern
# option on the command line or in ~/.rspec, .rspec or `.rspec-local`.
#
# The following line is provided for convenience purposes. It has the downside
# of increasing the boot-up time by auto-requiring all files in the support
# directory. Alternatively, in the individual `*_spec.rb` files, manually
# require only the support files necessary.
#
# Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

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

RSpec.configure do |config|
  # 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 = false

  # RSpec Rails can automatically mix in different behaviours to your tests
  # based on their file location, for example enabling you to call `get` and
  # `post` in specs under `spec/controllers`.
  #
  # You can disable this behaviour by removing the line below, and instead
  # explicitly tag your specs with their type, e.g.:
  #
  #     RSpec.describe UsersController, :type => :controller do
  #       # ...
  #     end
  #
  # The different available types are documented in the features, such as in
  # https://relishapp.com/rspec/rspec-rails/docs

ENV["RAILS_ENV"] ||= 'test'

到

移除

Rails.env = 'test'

由于RAILS_ENV环境变量应该足以进行配置
嗯，我不确定我做错了什么，但是通过撤消我为
数据库_cleaner
所做的所有配置：

卸载
数据库\u cleaner
gem
从
spec\u helper
和
rails\u helper
然后，在重新安装
数据库并取消对此行的注释后，执行以下操作：

Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

通过我的
rails\u助手
，我能够让
数据库清理器
按预期恢复工作。谢谢大家。
在我的例子中，当我使用
dotenv rails
gem时，它是在.env文件中指定的数据库连接。出于某些原因，database_cleaner更喜欢从那里连接，而不是rails应用程序配置
 如果有人在寻找这个问题的另一个潜在来源，我在
.bashrc
文件中随机定义了
$DATABASE\u URL
，直接指向我的开发数据库。我花了几个小时才找到它。
我很感激这是一篇老文章，但我今天遇到了这个问题。
我用pry和我的
ENV['RAILS\u ENV']='test'
但是我的
ENV['DATABASE\u URL']
以以下形式设置到我的开发数据库：
postgres://localhost/my_dev_db

我在
rails\u helper.rb
中的数据库清理器配置中添加了一行，以更改为我的测试数据库，如下所示：

  config.before(:suite) do
    ActiveRecord::Base.establish_connection(ENV['DATABASE_TEST'])
    DatabaseCleaner.clean_with(:truncation)
  end

其中ENV['DATABASE_TEST']的形式为：
postgres://localhost/my_test_db

这为我解决了这个问题。
你的database.yml是什么样子的？@SergioTulentsev我刚刚编辑了这个问题，将
数据库包括在内。yml
我尝试了这个，但没有成功。
development env
数据库仍然被清除。如何在
gem文件中包含
database\u cleaner
？它应该只驻留在您的测试组中：
gem'database_cleaner'，group:：test
yes，@stve它与rspec rails、capybara、factory_girl_rails、e.t.c一起包含在测试组中。这解决了使用vagrant时的相同问题（开发数据库被擦除），我在环境中设置RAILS_ENV的地方我使用Docker并发现了相同的东西。从Docker（Macbook）外部运行rspec，获取
.env
文件并清除我的数据库。将我的
.env
重命名为
dev.env
并更新
docker compose.yaml
为我解决了这个问题。
