How do I use the Draper Gem?

To use the Draper Gem, start by installing it via the command line with gem install draper. Then, you can include it in your Ruby application.

What are the main features of the Draper Gem?

The Draper Gem provides decorators for your Ruby objects, allowing you to add presentation logic to your models without cluttering them.

Can you give me an example of how to create a decorator?

Sure! First, create a decorator class that inherits from Draper::Decorator. Then, define methods to add presentation logic. For example:

class ProductDecorator < Draper::Decorator
  delegate_all

  def formatted_price
    h.number_to_currency(object.price)
  end
end

How do I apply the decorator to a model instance?

You can apply the decorator by calling decorate on your model instance. For example:

product = Product.find(1)
decorated_product = product.decorate
puts decorated_product.formatted_price
