ArgumentError: Factory not registered - Rails 5

Question

As I found this is a very common problem, but I still can not solve it.

I create a user factory (I use Devise), in spec/factories/users.rb:

FactoryGirl.define do
  factory :user do
    first_name "Jonas"
    last_name "Sniegas"
    email "[email protected]"
    password "asdfasdf"
    password_confirmation "asdfasdf"
  end
end

And try to create it from test console ( rails c -e test ):

FactoryGirl.create(:user)

And then:

ArgumentError: Factory not registered: user from /Users/user/.rvm/gems/ruby-2.3.0/gems/factory_girl-4.7.0/lib/factory_girl/registry.rb:24:in find' from /Users/user/.rvm/gems/ruby-2.3.0/gems/factory_girl-4.7.0/lib/factory_girl/decorator.rb:10:in method_missing' from /Users/user/.rvm/gems/ruby-2.3.0/gems/factory_girl-4.7.0/lib/factory_girl.rb:85:in factory_by_name' from /Users/user/.rvm/gems/ruby-2.3.0/gems/factory_girl-4.7.0/lib/factory_girl/factory_runner.rb:12:inrun' from /Users/user/.rvm/gems/ruby-2.3.0/gems/factory_girl-4.7.0/lib/factory_girl/strategy_syntax_method_registrar.rb:20:in block in define_singular_strategy_method' from (irb):1 from /Users/user/.rvm/gems/ruby-2.3.0/gems/railties-5.0.6/lib/rails/commands/console.rb:65:in start' from /Users/user/.rvm/gems/ruby-2.3.0/gems/railties-5.0.6/lib/rails/commands/console_helper.rb:9:in start' from /Users/user/.rvm/gems/ruby-2.3.0/gems/railties-5.0.6/lib/rails/commands/commands_tasks.rb:78:in console' from /Users/user/.rvm/gems/ruby-2.3.0/gems/railties-5.0.6/lib/rails/commands/commands_tasks.rb:49:in run_command!' from /Users/user/.rvm/gems/ruby-2.3.0/gems/railties-5.0.6/lib/rails/commands.rb:18:in ' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:293:in require' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:293:inblock in require' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:259:in load_dependency' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:293:inrequire' from /Users/user/Desktop/Ruby/Test/bin/rails:9:in <top (required)>' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:287:inload' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:287:in block in load' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:259:inload_dependency' from /Users/user/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.6/lib/active_support/dependencies.rb:287:in load' from /Users/user/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:inrequire' from /Users/user/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'

Gemfile:

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"

I also tried to add FactoryGirl.find_definitions in the before do block in spec/rails_helper.rb and specify all factories in one file - spec/factories.rb. Nothing seems to work..

Any help on this?

Answer 1

Problem was with Spring... Had to stop it - spring stop.

Now everything works well. I will leave this answer since in those many many questions and answers I went through, no-one suggested to stop preloader...
