Skip callback on create Rails

Question

I would like to create an Active Record model for Rspec test.

However, this model has callbacks, namely: before_create and after_create method (I think these methods are called callbacks not validation if I am not wrong).

Is there a way to create an object without triggering the callbacks?

Some previous solutions I have tried / does not work for my case:

Update Method:

update_column and other update methods will not work because I would like to create an object and I can't use update methods when the object does not exist.

Factory Girl and After Build:

FactoryGirl.define do
  factory :withdrawal_request, class: 'WithdrawalRequest' do
    ...
    after(:build) { WithdrawalRequest.class.skip_callback(:before_create) }
  end
end

Failure/Error: after(:build) { WithdrawalRequest.class.skip_callback(:before_create) }

NoMethodError: undefined method `skip_callback' for Class:Class

Skip Callback

WithdrawalRequest.skip_callback(:before_create)

withdrawal_request = WithdrawalRequest.create(withdrawal_params)

WithdrawalRequest.set_callback(:before_create)

Failure/Error: WithdrawalRequest.skip_callback(:before_create)

NoMethodError:undefined method `_before_create_callbacks' for #

How to save a model without running callbacks in Rails

I have also tried

WithdrawalRequest.skip_callbacks = true

Which does not work too.

---------- EDIT -----------

My factory function is edited to:

after(:build) { WithdrawalRequest.skip_callback(:create, :before, :before_create) }

My before_create function looks like this:

class WithdrawalRequest < ActiveRecord::Base
  ...
  before_create do
    ...
  end
end

---------- EDIT 2 -----------

I changed the before_create to a function so that I can reference it. Is either of these a better practice?

class WithdrawalRequest < ActiveRecord::Base
  before_create :before_create
  ...
  def before_create
    ...
  end
end

Based on the referenced answer:

FactoryGirl.define do
  factory :withdrawal_request, class: 'WithdrawalRequest' do
    ...
    after(:build) { WithdrawalRequest.skip_callback(:create, :before, :callback_to_be_skipped) }
   #you were getting the errors here initially because you were calling the method on Class, the superclass of WithdrawalRequest

    #OR
    after(:build) {|withdrawal_request| withdrawal_request.class.skip_callback(:create, :before, :callback_to_be_skipped)}

  end
end
