How to skip validations when using the `validate` method?

I am using Ruby on Rails 3.2.9. I implemented a custom validator and I would like to skip validations (on creating a new object in a migration file) when using the validate method. In general I can use :without_protection => true as a parameter of the create! method but in my case (see the code below) it seems do not work: validation are not skipped.

class Article < ActiveRecord::Base
  validate do
    # custom validation code
  end
end

How can I skip validations?

Without protection does not turn off validations, it allows you to mass-assign protected attributes. To save without validating:

new_record = Article.new
new_record.save(:validate => false)

You'll have to ensure that all of the other validations are disabled in order for this to be effective. ActiveRecord cannot selectively disable validations, but can omit them entirely.

For instance:

class Article < ActiveRecord::Base
  validate :something,
    :if => :validations_are_turned_on?

  validate :always

protected
  def validations_are_turned_on?
    !@validations_disabled
  end
end

Tagging any of the non-essential validations with the appropriate :if condition should work. In this case if @validations_disabled is not set then all validations will run.
