Routing Error No route matches "/users" Ruby on Rails Tutorial: Learn Rails by Example, by Michael Hartl

Question

I'm following Ruby on Rails Tutorial: Learn Rails by Example, by Michael Hartl.

http://ruby.railstutorial.org/chapters/a-demo-app#sec:a_micropost_microtour

Problem started: So, when I typed:

$ rails generate scaffold Micropost content:string user_id:integer

the command went through fine.

However, when I typed: $ bundle exec rake db:migrate

I get the errors below:

K-MacBook-Pro:demo_app ka$ bundle exec rake db:migrate
WARNING: 'require 'rake/rdoctask'' is deprecated.  Please use 'require
'rdoc/task' (in RDoc 2.4.2+)' instead.

What I have tried:

I copied "gem "rake", "0.8.7"" to my Gemfile I ran bundle update rake Then I tried: $ bundle exec rake db:migrate (in /Users/ka/rails_projects/demo_app) After this it brings me back to the $prompt.

When I open http://localhost:3000/users I get the following error:

Routing Error No route matches "/users" No route matches "/Users"

I don't see any errors when you run rake db:migrate, only warnings. — Andrew Marshall

The problem is that you don't have any path setup in config/routes.rb for Users.

If User is a resource, you can add the following to the file:

# config/routes.rb
resources :users

This will allow you to use your /users, users_path, user_path(@user), etc.

The rdoc warnings you are getting are just that, warnings. They are most likely due to a gem that needs updating (on their end). Keep your gems up to date whenever you can, and you will eventually see that warning go away (most likely).
