rails中的以下方法有什么区别？

Question

users_path和user_path(user1)
我想前者去索引动作，后者去特定用户的show动作

Answer 1

您的期望是正确的：

users_path在

时提供控制器操作users#index的路径

user_path(user1)提供控制器操作users#show的路径，其中params[:id]设置为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

并且

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

或

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