Factory_bot: Factory already registered, beginner question

[stephenson]

Hi factory_bot community
First of all, thanks for putting all the work into factory_bot!

I am new to factory_bot, and can't understand why I get the DuplicateDefinitionError with the following factory file:

FactoryBot.define do
  sequence :email do |n|
    "person#{n}@example.com"
  end

  sequence :name do |n|
    "Name #{n}"
  end

  factory :employee do
    email
    company
    name
  end

  factory :project do
    company
    name
  end

  factory :company do
    name "Test Company"

    factory :full_company do
      transient do
        employees_count 5
        projects_count 2
      end

      after(:create) do |company, evaluator|
        create_list(:employee, evaluator.employees_count, company: company)
        create_list(:project, evaluator.projects_count, company: company)
      end
    end
  end
end

Can someone point me in the direction of what I am doing wrong?

Thanks!

@stephenson hmm, there's nothing obvious here that seems out of place; are there multiple factory files (e.g. spec/factories.rb and spec/factories/employee.rb) where there might be overlap? Could you provide the backtrace from the exception in hopes that it leads to further clues?

@joshuaclayton Only one factory file in the project, this is the full output in the terminal (is that the backtrace? Sorry noob here):

@stephenson looks like test/factories/projects.rb is causing problems; any chance you could verify?

[stephenson]

@joshuaclayton you are completely right, I did not see that the rails generator created a factory file. Still learning!

Thanks a lot for your time!

Thanks!
