Using scaffolding

rubyonrails-talk

Hi all,

I've been following this online book: http://ruby.railstutorial.org/chapters/a-demo-app#sec-modeling_demo_users

I ran the commands: rails generate scaffold User name:string email:string bundle exec rake db:migrate

As I understand it I should be able to go to the following URL and it should display a list of users: http://localhost:3000/users

However I get this error:

"Routing Error

No route matches [GET] "/users"

Try running rake routes for more information on available routes."

Have you restarted the server since you made the change? It is not necessary to restart when changing model/view/controller files but if any configuration files (such as routes.rb) are changed then it is necessary to restart it.

Othewise, did you try running rake routes to show you the routes available, as suggested? You may not yet be able to fully understand the output but it is worth following the suggestion anyway. Have a look at config/routes.rb. I would have expected the generate scaffold command to have added something like

resources :users

to it.

In the first chapter another application was created, could it be that the rails server is serving the first application instead of the one from the second chapter of the book?

Assuming that you are running the commands from within the folder of the second application then no. I presume you have run rails server from within the second application.

Hi Colin,

Closing the terminal and restarting the server did the trick, thank you.

Hi Colin,

You should be able to stop the server using Ctrl+C (on linux anyway). Not sure about other systems.

I tried that a number of times but it didn’t work, closing the terminal window was the only way to get it to work.

What do you mean "it didn't work"? Do you mean that it did not stop the server or it stopped the server but restarting it did not fix the problem? If the latter were you in the correct directory in the terminal? If the former what OS are you using?

Restarting the server didn’t fix the problem, I believe I was in the correct directory but that maybe was the problem. I’ve since closed the terminal down and it’s now working. This is certainly the fastest setup I’ve ever experienced in getting a framework up and running. Hopefully today’s progress will be good too!

Cheers,
