ValidationSkipper

Forked from npearson72/validation_skipper.

This Rails gem lets you easily declare which attribute validations to skip in you models, and choose when to skip them in your controllers.

Installation

Add this line to your application's Gemfile:

gem 'validation_skipper'

And then execute:

bundle

Usage

In your model

Let's say you have a User model with a name, phone, and password. In your code, you might have validations like these:

validates :name, :presence => true
validates :phone, :presence => true
validates :password, :presence => true

To implement ValidationSkipper, you would follow these simple steps.

Step 1: Include the ValidationSkipper module in the model

include ValidationSkipper

Step 2: Declare which validations are allowed to be skipped

can_skip_validation_for :name, :phone, :password

(Note: this does not automatically skip them, but makes them eligible for skipping)

Step 3: Change the validations to look like these

validates :name, :presence => true, :unless => Proc.new { |u| u.skip_name_validation? }
validates :phone, :presence => true, :unless => Proc.new { |u| u.skip_phone_validation? }
validates :password, :presence => true, :unless => Proc.new { |u| u.skip_password_validation? }

In your controller

Now just pass the names of the fields you want to skip validation for from within your controller, ex:

def create
  @user = User.new(params[:user])
  @user.skip_validation_for :name, :phone
  # The rest of your code goes here...
end

This will now skip the validations for name and phone only, but still validate for password.

And there you go, anytime you want the same effect elsewhere, just follow this approach.

Enjoy!
