# Dicer

useful DCI for Rails.

for example:

```ruby

class User < ActiveRecord::Base

  has_many :purchases

end

module Customer

  include Dicer::Behavior

  def purchase(book)

    self.purchases.create(book: book)

  end

end

class PurchaseContext < Dicer::Context

  describe User do

    it_behaves_like Customer

  end

end

--

context(PurchaseContext.new)

user = User.where(id: session[:user_id]).first

book = Book.where(id: params[:id]).first

user.purchase(book)

```

Dicer is faster than `#extend` and `SimpleDelegator`

```
