How to implement :with_trait using Fabrication

Question

I'm considering migrating many mocks from FactoryGirl over to the Fabrication gem.

However, so far I've been unable to find any information on implementing the trait pattern available in FactoryGirl.

Is there a generally accepted way to do this with Fabrication?

Thank you in advance for any answers or information.

Answer 1

Fabrication doesn't have syntax sugar for traits. As far as I understand, it is just a way to group and define inheritance.

In the case of this Factory: (which I pulled from this blog post)

FactoryGirl.define do
  factory :todo_item, aliases: [:incomplete_todo_item] do
    name 'Pick up a gallon of milk'
    complete false

    factory :complete_todo_item do
      complete true
    end
  end
end

You would do the same thing in Fabrication like this:

Fabricator(:todo_item, aliases: :incomplete_todo_item) do
  name 'Pick up a gallon of milk'
  complete false
end

Fabricator(:complete_todo_item, from: :todo_item) do
  complete true
end

If you do decide to convert you can send to the mailing list with any specific questions. I am always happy to help figure out how to get things working or improve the efficiency of your fabricators.
