Present And Call Shorthand method for using the following call

Examples:

def prac(object, method, *args)
  return if object.nil? || method.nil?
  presenter_for(object).send(method.to_sym, *args)
end

#presenter_for(model, klass = nil) {|presenter| ... } ⇒ Object

We can use this to give a block and wrap all the presenter methods in the block. This shows clearly that we are using a presenter without the explicit assign statement. Some magic happens to initiate a new presenter with the model and the view context

Parameters:

  • model (Object) —

    any type of object that needs to be presented

  • klass (KlassName) (defaults to: nil) —

    a different presenter klass

Yields:

  • (presenter)

Returns:

  • model presenter instance
