如何打印FactoryGirl.create进行的Model.create调用？

Question

Is there any way to print the ActiveRecord operations called by FactoryGirl.create?

Say we have a factory :foo of model Foo . Running FactoryGirl.create(:foo) , creates a database entry for the model Foo and some other entries for different models, say Bar , Car , etc.

Is there any way in which we could convert this FactoryGirl.create(:foo) command into its underlying Model.create commands?

For example

FactoryGirl.create(:foo)

should break into

Foo.create(name: 'some name', ...)
Bar.create(field_value: 'asdf', ....)
Car.create(field_value: 'asdf1231', ....)
...

factory_girl calls save! when it creates a model, so you can get at least part way there by overriding save! in each of your models. Put this in config/initializers/print_model_save.rb :

class ActiveRecord::Base
  alias_method :original_save!, :save!

  def save!
    puts "#{self.class.name}.create! #{attributes.symbolize_keys.inspect}"
    original_save!
  end

end

That will work for simple attributes. Complex attributes might require more complicated argument printing. Try it and see.
