When converting a standard route helper method to a nested one, in each case carefully consider whether to use a local variable vs. an instance variable. For example owner or @owner; pet or @pet.

Target Controller Action	HTTP Request Method	Route Helper Methods	Sample URLs
index	GET	owner_pets_path(owner)	owners/5/pets
show	GET	owner_pet_path(owner, pet) or [owner, pet]	owners/5/pets/3
new	GET	new_owner_pet_path(owner)	owners/5/pets/new
edit	PUT	edit_owner_pet_path(owner, pet)	owners/5/pets/3/edit
destroy	DELETE	owner_pet_path(owner, pet) or [owner, pet]
create	POST	owner_pet_path(owner, pet) or [owner, pet]
update	PUT	owner_pet_path(owner, pet) or [owner, pet]
