## Usage

Use the method `validates_duplicity_of` with an attribute in your Rails model. The scope is optional.

```ruby

class Post < ActiveRecord::Base

  validates_duplicity_of :name

end

post = Post.create name: "Foo"

post.name

=> "Foo"

post = Post.create name: "Foo"

post.name

=> "Foo (1)"

class Note < ActiveRecord::Base

  validates_duplicity_of :title, scope: :user_id

end

note = Note.create title: "Bar", user_id: 1

note.title

=> "Bar"

note = Note.create title: "Bar", user_id: 1

note.title

=> "Bar (1)"

```
