Answer 1

I had this problem too. In my case there were two files with the same code, like this:

FactoryGirl.define do
  factory :user do
  end
end

One file was named "Useres.rb" and the other "User.rb" so I just deleted "Useres.rb" and fixed the error.

Answer 2

Please try following these steps

1) I looked for all occurrences of "factory_girl" from my RAILS_ROOT:

find . -name "*.rb" | xargs grep "factory_girl"

2) Because this was a full engine plugin "app" that I created via "rails plugin new --mountable", I had a file under RAILS_ROOT//lib/ called "engine.rb". It had:

config.generators do |g|
  g.test_framework      :rspec,        :fixture => false
  g.fixture_replacement :factory_girl, :dir => 'spec/factories'
  g.assets false
  g.helper false
end

3) I also had the following in my spec_helper.rb file:

Dir["#{File.dirname(FILE)}/factories/*/.rb"].each { |f| require f }

4) the g.fixture_replacement line in engine.rb and the Dir line in spec_helper.rb were initializing the factories twice. I commented out the one from spec_helper.rb and that fixed the problem.

Alternatively, you can leave in spec_helper.rb and comment out in engine.rb.

Both fixed the problem in my case.

Answer 3

Check to see if you added factories through the model generator. My generator made a model and I added one to my main factory.rb file. Deleting the automatically generated ones worked for me.

Answer 4

I also ran with the same issue and commenting out a single line in spec_helper.rb file solved my problem.

Try commenting out this line from spec_helper.rb file and you should be good.

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

Loading factory girl into a development console will do this too:

require 'factory_girl_rails'; reload!; FactoryGirl.factories.clear; FactoryGirl.find_definitions

will raise a FactoryGirl::DuplicateDefinitionError on a sequence under Factory Girl v4.4.0.

It seems the sequences get handled differently within FG and simply wrapping all sequences in a rescue block will solve the issue.

For example:

  begin
    sequence :a_sequence do |n|
      n
    end
    sequence :another_sequence do |n|
      n*2
    end
  rescue FactoryGirl::DuplicateDefinitionError => e
    warn "#{e.message}"
  end

I had the same problem- make sure you aren't loading FactoryGirl a second time in your spec/support/env.rb file.
