Is there a benefit to using resource vs resources in your Rails routes? -

to have more 1 route on course resource, use resources :course. use singular resource 1 route courses#new. feasible use resources :course if have 1 route? figure easier later on add course routes if plural. there downside making resource plural go?

singular resources like:

    resource :course 

generate 6 routes instead of 7. plural index route left. main reason differing between singular/ plural resources expressiveness. sometimes, have resource clients without referencing id. example, /course show current course. in case, can use singular resource map /course (rather /course/:id) show action:

1. get
   • /course/new
   • courses#new
   • return html form creating course
2. post
   • /course
   • courses#create
   • create new course
3. get
   • /course
   • courses#show
   • display 1 , course resource
4. get
   • /course/edit
   • courses#edit
   • return html form editing course
5. patch/put
   • /course
   • courses#update
   • update 1 , course resource
6. delete
   • /course
   • courses#destroy
   • delete course resource

read singularize resource routes, if singular!
please consider decision. if course resource singular in context choose singular resource, otherwise choose multiple resources.
