Just add some experiment code to figure out something

1. REST usage as follows:
Helper			GET		POST		PUT			DELETE
event_path(@event)		/events/1 			/events/1		/events/1
				show action			update action           destroy action
events_path			/events		/events
				index action	create action
edit_event_path(@event)	/events/1/edit
				edit action
new_event_path		/events/new
				new action

2.Try to figure out the association(belongs_to, has_many, etc), still not that clear.
