ruby on rails 4 - fake - database_cleaner está borrando mi base de datos de desarrollo

fake data rails

Question

Tengo database-cleaner configurado para mi aplicación Rails 4, cada vez que ejecuto la prueba, descubro que mi base de datos se anula tanto en el entorno de test como de development .

Mis configuraciones están en rails_helper como sigue:

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
  config.infer_spec_type_from_file_location!

  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
  end

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


  config.mock_with :rspec

  config.before(:all) do
    ActiveRecord::Base.skip_callbacks = true
  end

  config.after(:all) do
    ActiveRecord::Base.skip_callbacks = false
  end

end

¿Cómo puedo asegurarme de que el limpiador limpie el db en el test environment sin tocar mi development ?

Mi database.yml es el siguiente:

# PostgreSQL. Versions 8.2 and up are supported.
#
# Install the pg driver:
#   gem install pg
# On OS X with Homebrew:
#   gem install pg -- --with-pg-config=/usr/local/bin/pg_config
# On OS X with MacPorts:
#   gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
# On Windows:
#   gem install pg
#       Choose the win32 build.
#       Install PostgreSQL and put its /bin directory on your path.
#
# Configure Using Gemfile
# gem ''pg''
#
default: &default
  adapter: postgresql
  encoding: unicode
  # For details on connection pooling, see rails configuration guide
  # http://guides.rubyonrails.org/configuring.html#database-pooling
  pool: 5

development:
  <<: *default
  database: directory-service_development

  # The specified database role being used to connect to postgres.
  # To create additional roles in postgres see `$ createuser --help`.
  # When left blank, postgres will use the default role. This is
  # the same name as the operating system user that initialized the database.
  #username: directory-service

  # The password associated with the postgres role (username).
  #password:

  # Connect on a TCP socket. Omitted by default since the client uses a
  # domain socket that doesn''t need configuration. Windows does not have
  # domain sockets, so uncomment these lines.
  #host: localhost

  # The TCP port the server listens on. Defaults to 5432.
  # If your server runs on a different port number, change accordingly.
  #port: 5432

  # Schema search path. The server defaults to $user,public
  #schema_search_path: myapp,sharedapp,public

  # Minimum log levels, in increasing order:
  #   debug5, debug4, debug3, debug2, debug1,
  #   log, notice, warning, error, fatal, and panic
  # Defaults to warning.
  #min_messages: notice

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: directory-service_test

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
#   DATABASE_URL="postgres://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
#   production:
#     url: <%= ENV[''DATABASE_URL''] %>
#
production:
  <<: *default
  database: directory-service_production
  username: directory-service
  password: <%= ENV[''DIRECTORY-SERVICE_DATABASE_PASSWORD''] %>

Answer 1

Bueno, no estoy seguro de lo que estaba haciendo mal, pero al deshacer todas las configuraciones que tenía para database_cleaner :

1. desinstalando la gema database_cleaner
2. eliminando todas las configuraciones relacionadas de ambos, spec_helper y rails_helper

Y luego seguir esta guía de Avdi Grimm , luego de reinstalar la database_cleaner gem y también descomentar esta línea:

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

de mi rails_helper , pude hacer que database_cleaner vuelva a funcionar como se esperaba. Gracias a todos.

Answer 2

En mi caso, fue la conexión a la base de datos especificada en el archivo .env cuando utilicé dotenv-rails gem. Por alguna razón, database_cleaner prefiere la conexión desde allí en lugar de la configuración de la aplicación Rails.

Answer 3

Si alguien está buscando otra fuente potencial de este problema, aleatoriamente tenía $DATABASE_URL definido en mi archivo .bashrc para apuntar directamente a mi base de datos de desarrollo. Me llevó unas horas encontrar eso.

Answer 4

Yo recomendaría cambiar

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

a

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

y eliminar

Rails.env = ''test''

como la variable de entorno RAILS_ENV debería ser suficiente para la configuración
