FactoryGirl problems - `factory ': wrong number of arguments (0 for 1) (ArgumentError)

Question

I am working on a Ruby on Rails tutorial and I am so close to ending, but Factory Girl does not make my life easier.

I cannot run any of the specification files calling factory.

require 'spec_helper' require 'factory_girl_rails' describe User do before(:each) do @attr = { :name => "Example User", :email => " [e-mail] ", :password => "foobar", :password_confirmation => "foobar" } end it "should create a new instance given valid attributes" do User.create!(@attr) end it "should require a name" do no_name_user = User.new(@attr.merge(:name => "")) no_name_user.should_not be_valid end it "should require an email address" do no_email_user = User.new(@attr.merge(:email => "")) no_email_user.should_not be_valid end it "should reject names that are too long" do long_name = "a" * 51 long_name_user = User.new(@attr.merge(:name => long_name)) long_name_user.should_not be_valid end it "should accept valid email addresses" do addresses = %w[ [e-mail] [e-mail] [e-mail] ] addresses.each do |address| valid_email_user = User.new(@attr.merge(:email => address)) valid_email_user.should be_valid end end it "should reject invalid email addresses" do addresses = %w[ user@foo ,com user_at_foo.org example.user@foo. ] addresses.each do |address| invalid_email_user = User.new(@attr.merge(:email => address)) invalid_email_user.should_not be_valid end end it "should reject duplicate email addresses" do #put user with given email address into the database User.create!(@attr) user_with_duplicate_email = User.new(@attr) user_with_duplicate_email.should_not be_valid end it "should reject email addresses identical up to case" do upcased_email = @attr[:email].upcase User.create!(@attr.merge(:email => upcased_email)) user_with_duplicate_email = User.new(@attr) user_with_duplicate_email.should_not be_valid end describe "password validations" do it "should require a password" do User.new(@attr.merge(:password => "", :password_confirmation => "")).should_not be_valid end it "should reject short passwords" do short = "a" * 5 hash = @attr.merge(:password => short, :password_confirmation => short) User.new(hash).should_not be_valid end it "should reject long passwords" do long = "a" * 41 hash = @attr.merge(:password => long, :password_confirmation => long) User.new(hash).should_not be_valid end end describe "password encryption" do before(:each) do @user = User.create!(@attr) end it "should have an encrypted password attribute" do @user.should respond_to(:encrypted_password) end it "should set the encrypted password" do @user.encrypted_password.should_not be_blank end it "should be true if passwords match" do @user.has_password?(@attr[:password]).should be_true end it "should be false if the passwords don't match" do @user.has_password?("invalid").should be_false end describe "authenticate method" do it "should return nil on email/password mismatch" do wrong_password_user = User.authenticate(@attr[:email], "wrongpass") wrong_password_user.should be_nil end it "should return nil for an email address with no user" do nonexistent_user = User.authenticate(" [e-mail] ", @attr[:password]) nonexistent_user_should be_nil end it "should return the user on email/password match" do matching_user = User.authenticate(@attr[:email], @attr[:password]) matching_user.should == @user end end end describe "admin attribute" do before(:each) do @user = User.create!(@attr) end it "should respond to admin" do @user.should respond_to(:admin) end it "should not be an admin by default" do @user.should_not be_admin end it "should be convertible to an admin" do @user.toggle!(:admin) @user.should be_admin end end describe "micropost associations" do before(:each) do @user = User.create{@attr} @mp1 = FactoryGirl.create(:micropost, :user => @user, :created_at => 1.day.ago) @mp2 = FactoryGirl.create(:micropost, :user => @user, :created_at => 1.hour.ago) end it "should have a microposts attribute" do @user.should respond_to(:microposts) end it "should have the right microposts in the right order" do @user.microposts.should == [@mp2, @mp1] end it "should destroy associated microposts" do @user.destroy [@mp1, @mp2].each do |micropost| Micropost.find_by_id(micropost.id).should be_nil end end end end 

factories.rb

  #by using the symbol ':user', we get Factory Girl to simmulate the User model require 'spec_helper' FactoryGirl.define do factory :user do |user| user.name "User Name" user.email " [e-mail] " user.password "foobar" user.password_confirmation "foobar" end factory.sequence :email do |n| "person-#{n}@example.com" end factory :micropost do |micropost| micropost.content "Foo bar" micropost.association :user end end 

This is the error message I get:

I also tried restarting spork and several combinations suggested here for syntax with FactoryGirl.

HELP !!!!

Answer 1

You do not need to loop when creating an object in the factory, and you can use the sequence to define the object at the same time, try the following:

 FactoryGirl.define do factory :user do sequence(:name) { |n| "User Name #{n}" } sequence(:email) { |n| "person-#{n}@example.com" } password "foobar" password_confirmation "foobar" end factory :micropost do content "Foo bar" user end end 

Answer 2

I think the problem is how you declare the factories passing the block. Try declaring a micropost factory, for example, as follows:

 factory :micropost do content "Foo bar" association :user end
