`autodetect ': non è stato rilevato alcun ORM noto

Question

Impossibile pulire i dati utilizzando database_cleaner.rb; lanciando il seguente problema sui test di corsa.

/Users/prashanth_sams/.rvm/gems/ruby-2.0.0-p598/gems/database_cleaner-1.3.0/lib/database_cleaner/base.rb:147:in `rilevare automaticamente ': Non sono noti È stato rilevato ORM! ActiveRecord, DataMapper, Sequel, MongoMapper, Mongoide, Ciclomotore o CouchPotato, Redis o Ohm caricato? (DatabaseCleaner :: NoORMDetected)

database_cleaner.rb

require 'database_cleaner' 

DatabaseCleaner.strategy = :truncation 

RSpec.configure do |config| 
    config.use_transactional_fixtures = false 
    config.before :each do 
    DatabaseCleaner.start

    config.after :each do 
    DatabaseCleaner.clean 
    end

Answer 1

Usa mio setup, sembra funzionare bene per RDBMS (che cked su MySQL e Postgres), alla tua database_cleaner.rb:

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 

    # this may be needed for Capybara tests and for testing after_commit hooks 
    config.before(:each, strategy: :truncation) do 
    DatabaseCleaner.strategy = :truncation 
    end 

    config.before(:each) do 
    DatabaseCleaner.start 
    end 

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

Se si desidera utilizzare truncation strategia, basta usare describe 'something', strategy: :truncation o it 'something', strategy: truncation.

Answer 2

Ho avuto lo stesso problema su controller_spec. 'autodetect': No known ORM was detected! Is ActiveRecord, DataMapper, Sequel, MongoMapper, Mongoid, Moped, or CouchPotato, Redis or Ohm loaded? (DatabaseCleaner::NoORMDetected)

Ho risolto richiedendo il file rails_helper sulle specifiche del controller.

require 'rails_helper' 

In rails_helper.rb richiede il file 'database_cleaner'.

require 'database_cleaner' 

Answer 3

ho avuto questo problema (on Rails 5.1) e la ragione era che avevo

config.before(:suite) do 
    DatabaseCleaner.clean_with :truncation 
end 

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

config.before(:each) do 
    DatabaseCleaner.start 
end 

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

nel mio spec_helper.rb.

Ho inserito require 'database_cleaner in spec_helper.rb.

Quindi alla fine ho spostato entrambe le cose su rails_helper.rb e questo ha risolto il problema per me.
