Simple Range validator

Validate fields of type Range. Also contains simple validators for Array values and types respectively ;)

gem 'simple_range_validator'

Here using Mongoid's built in Range field support ;)

class Search
  include Mongoid::Document

  field :cost, type: Range

  validates :cost, range:  {within: 0..40000 }
end

Search.new cost: (0..2000)

And here using factory_girl gem:

FactoryGirl.define do
  sequence(:cost_range) { [ (0..2000), (2000..4000), (4000..8000) ].sample }

  factory :search do
    cost  { FactoryGirl.generate(:cost_range) }
  end
end

Create a Search instance via factory (requires Factory Girl macros enabled):

create :search

Could make sense to integrate both of these gems ;)

class Search
  include Mongoid::Document

  field :color, type: Array

  # you can also use only: as the option
  validates :color, array:  {in: ['red', 'blue', 'green'] }
end

class Search
  include Mongoid::Document

  field :color, type: Array

  # you can also use in: as the option
  validates :color, array_types:  {only: [String, Fixnum] }
end

class Search
  include Mongoid::Document

  field :period, type: Timespan

  # you can also use in: as the option
  validates :period, timespan:  {from: 1.day.ago, to: 14.days.from_now }
end

Simple as pie ;)

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
• Fork the project.
• Start a feature/bugfix branch.
• Commit and push until you are happy with your contribution.
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
