Proxy objects with fallbacks. Useful for creating stubs with partially defined objects.

Add this line to your application's Gemfile:

gem 'stub'

And then execute:

$ bundle

Or install it yourself as:

$ gem install stub

Inherit Stub::Abstract (or Stub::Template::Abstract) and define __stub__ method:

class MyStub < Stub::Abstract
	module Methods
		def __stub__ method_name, *args, &block
			# Do something when method fails on the proxied object
			# or returns nil.
		end
	end
end

See also Stub::Template::Prototype as a working example.

Use a proxied object to generate placeholders in place of absent attributes & methods:

render Stub::Template::Prototype.new(MyModel.new)

Later you can use this rendered template in Prototype's new Template() and evaluate it with data from MyModel.find. Example (don't forget escaping in real-life code):

var template = '<%= render Stub::Template::Prototype.new(MyModel.new) %>';
var record   = JSON.parse('<%= my_model.to_json %>');

text = new Template(template).evaluate(record);

3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
