# Delegate-class

Using the default ruby delegate library, this gem is used to wrap the class _AND_ instance methods of another class.

(_Though I still don't know the real usage of it_)

You may want to use it like this:

##Usage

I found it can be used on these situations.

Lets say you are using Rails and has the model:

```ruby

   

class User < ActiveRecord::Base

end

```

And then you have an author delegator class, modified to make things like _#form_for_

```ruby

require "delegate"

class Author < SimpleDelegator

  def class

    __getojb__.class

  end

  def bookmates

    User.find(1)

  end

  def name

   super + "!"

  end

end

```

IMO, there are two bad things in these code:

 1. Redefine class

 2. Referencing the class you should be delegating

You may change it to:

```ruby

require "delegate/class"

class Author < ClassDelegator(User)

  def bookmates

    self.class.find(1)

  end

  def name

   super + "!"

  end

end

```

Now, you are delegating the instance and class methods to the wrapped class/object

## Instalation

[![Build Status](https://secure.travis-ci.org/bltavares/delegate-class.png)](http://travis-ci.org/bltavares/delegate-class)

It's is simple.

Hope you like it (:
