ruby-on-rails - rails中的以下方法有什么区别？

Question

users_pathuser_path(user1)
我猜前者用于索引操作，后者用于特定用户的显示操作

Answer 1

Your expectation is right:

users_pathgives the path to the controller action users#index while

user_path(user1)gives the path to controller action users#show with params[:id] set to user1.id

Answer 2

users_path returns /users
new_user_path returns /users/new
edit_user_path(:id) returns /users/:id/edit (for instance, edit_user_path(10) returns /users/10/edit)
user_path(:id) returns /users/:id (for instance, user_path(10) returns /users/10)

Answer 3

users_path will routes to users#index as you expected

和

user_path(user) will redirect to users#show if method is get

或者

It will redirect or routes to users#destroy if method is delete
