Validacity

Move your validation logic out of your models or form objects.

Usage

You can append validators on-fly and then remove some of them if not needed.

It can be very suitable if you need to validate different states of the same object differently. Say you're using a state machine and each state have it's own field set and the fields from other satates shouldn't be validated at this time.

Or perhaps you just have to many constructions like validate :blablabla, presence: true in your model and you want to get rid of it.

All you need is to add a concern to your model:

# app/models/user.rb

class User
  include Validacity::Validatable
  validations :user_personal_data
end

And generate a validator:

# app/validators/user_personal_data_validator.rb

class UserPersonalDataValidator
  validate :name, presence_of: true
  # ...a ton of different validators
end

Now call validator with the regular methods like:

user.valid?

Installation

Add this line to your application's Gemfile:

gem 'validacity'

And then execute:

$ bundle

Now run the validator installation command:

$ bundle exec rails g validacity:install

And the event validator:

$ bundle exec rails g validacity:validator Event
