路由错误没有路由匹配 [GET] “/index”

Question

I'm new to Rails. I've got a routing error bellow when I try to access http://localhost:3000/index.

No route matches [GET] "/index"
Rails.root: /Users/[...]/taskleaf

Routes

Helper  HTTP Verb   Path                Controller#Action
root_path   GET     /                   tasks#index

tasks_path  GET     /tasks(.:format)    tasks#index

            POST    /tasks(.:format)    tasks#create

[...]

Here is the content of my route.rb file:

Rails.application.routes.draw do
  root to: 'tasks#index'
  resources :tasks
end

I would be very grateful if you could help me out...

Answer 1

from what you've provided, try changing it to either '/' or '/tasks/index' then you may get what you're looking for.

Or, add this code in your routes.rb file get '/index', to: 'tasks#index' , which would direct /index path to the index action in your tasks controller.

Here is how Rails routing works: when you request '/index', it'll try to find #index route in your routes.rb file, which doesn't exist since the index action lies within your 'tasks' controller (from what I've seen from your codes). In the code, you defined the root page ('/') to be '/tasks/index' (try visiting '/' and '/tasks/index', they should be the same).

Remember, whenever you've seen a routing error, it is likely that you didn't define the route in routes.rb file

Feel free to give it a try and update here if there's any further errors/problems.
