#generate_add_methods(name) ⇒ Object

Generate dynamic class methods like add_focus, add_follow Favor.add_focus has at least two parameters as add_focus(operator,resource)

the operator is someone(maybe something) who has taken an action(context) on a resource
the resource is target
return an object with error when create favor failed

Even method could receive a block to assign more attributes, but it is not recommended Favor is designed to handle simple data structure, mostly for simple relation data

just the user click one button or touch one link, then a favor was created
