FactoryGirl, perché sono già registrato o non inizializzato?

Question

Sto cercando di fare un semplice test per il mio modello Course, ho scritto questa fabbrica:

FactoryGirl.define do 
    factory :course do 
    name 'How to be happy ?' 
    end 
end 

il course_spec.rb:

require "rspec" 
require 'factory_girl_rails' 
describe "When a course is created" do 

    it "can't be deleted if any student is enrolled to it" do 
    FactoryGirl.find_definitions 
    course = FactoryGirl.build(:course) 

    student= Student.create! 
    course.students << student 
    course.destroy 
    course.name.should !=nil 
    end 
end 

ma, raggiungo questa linea

course = FactoryGirl.build(:course) 

Ho ricevuto l'errore:

FactoryGirl::DuplicateDefinitionError: Factory already registered: course 

se io commento la: definizione di corso nella fabbrica, ottengo:

NameError: uninitialized constant Course 

Qualche idea per favore?

qui è la mia gemma envioronment:

Lo spec_helper.rb:

require 'spork' 




    Spork.prefork do 
     # Loading more in this block will cause your tests to run faster. However, 
     # if you change any configuration or code from libraries loaded here, you'll 
     # need to restart spork for it take effect. 
     ENV["RAILS_ENV"] ||= 'test' 
     require File.expand_path("../../config/environment", __FILE__) 
     require 'rspec/rails' 
     require 'rspec/autorun' 

     # Requires supporting ruby files with custom matchers and macros, etc, 
     # in spec/support/ and its subdirectories. 
     Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f} 

     RSpec.configure do |config| 
     # == Mock Framework 
     # 
     # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line: 
     #

     # 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 = true 

     # If true, the base class of anonymous controllers will be inferred 
     # automatically. This will be the default behavior in future versions of 
     # rspec-rails.

     # This code will be run each time you run your specs.

Answer 1

Hai provato a rimuovere questa riga?

FactoryGirl.find_definitions 

Sto usando Factory Girl (con il factory_girl_rails gemma) & Shoulda con un progetto 3.1 e non ho dovuto caricare in modo esplicito le definizioni.

Answer 2

Tutto quello che dovresti fare è require 'rspec_factory_girl' e poi le definizioni.

Generalmente se lo metti nella spec_helper.rb, richiederà tutti i file nella directory spec/, il che significa che se avete le vostre fabbriche definiti ad esempio nel spec/factories.rb, avranno caricato automaticamente.

Questo tuttavia richiede di aggiungere require 'spec_helper' nella parte superiore del file spec, che sembra non si sta facendo.

Se non si desidera utilizzare il file spec_helper.rb in questo modo, poi basta richiedere manualmente la definizione, come ad esempio require 'factories'.

Un piccolo trucco se stai usando qualcosa come spork e la necessità di caricare manualmente le fabbriche prima di ogni corsa

FactoryGirl.factories.clear 
# either this if you have multiple files under 'spec/factories', 
# or just load the single file, such as 'spec/factories.rb' 
Dir.glob("#{::Rails.root}/spec/factories/*.rb").each do |file| 
    load "#{file}" 
end 

edit: completo esempio di Spork

Spork.each_run do 
    require 'factory_girl_rails' 

    # reload all the models 
    Dir["#{Rails.root}/app/models/**/*.rb"].each do |model| 
    load model 
    end 

    # reload all factories 
    FactoryGirl.factories.clear 
    Dir.glob("#{::Rails.root}/spec/factories/*.rb").each do |file| 
    load "#{file}" 
    end 

    # reload routes 
    YourAppName::Application.reload_routes! 
end 

Answer 3

Nella mia caso, è accaduto quando ho accidentalmente messo due file di fabbrica che contengono la stessa chiave come segue:

Rails.root/spec/factories/book.rb 
Rails.root/spec/factories/books.rb 

Questo è ovvio, ma questa situazione si è verificata quando mi sono sviluppato in ambiente no-git (!) E ho inserito file sorgente da rsync (1). Quando ho rinominare book.rb a books.rb dal mio PC locale e rsync a dev-ENV, sia book.rb e books.rb esistono e questo ha causato la situazione qui ;-(

Answer 4

Ho anche incontrato questo errore:

FactoryGirl::DuplicateDefinitionError: Factory already registered: factory_name 

E ho risolto il problema aggiungendo :require => false nel mio Gemfile come questo:

gem 'factory_girl_rails', :require => false 

Poi richiedono nel test_helper.rb solo una volta da avere questa linea:

require 'factory_girl_rails' 

Answer 5

Ecco cosa ha funzionato per me in Rails 4.2.6

In rails_helper.rb aggiungere questi librarys

require 'factory_girl' 
require 'factory_girl_rails' 

aggiungere questi alla parte config

config.include FactoryGirl::Syntax::Methods
