DatabaseValidation

We write a lot of validations in our ActiveRecord models that already exist inside of our database. This gem automatically creates those validations.

Usage

We need more tools that use tools we already have

class Thing < ActiveRecord::Base
  include DatabaseValidation
end

What's automatically created

For now:

  • validates_uniquness_of (with scope)
  • validates_presence_of
  • validates_inclusion_of (for booleans)
  • validates_length_of :maximum, :allow_nil
  • validates_numericality_of :greater_than, :less_than, :allow_nil

Tested Adapters (probably others)

  • mysql
  • mysql2

Installation

# in your Gemfile
gem 'database_validation'
