'Routing Error No route matches [GET] "/"' when opening treebook application server address in browser

Hi there,

Originally when creating the treebook application I was getting the warning message 'Insecure world writable dir /usr/local in PATH, mode 040777'. I followed the advice in another post and used the command 'sudo chmod o-w /usr/local/'. I no longer get any warnings now, however, when I try to open the application server in the browser I get 'Routing Error No route matches [GET] "/"'.

Can anyone help?

Thanks, Rhys

It seems from your question that you think the two are connected? If they are then, well, good luck. :-) Otherwise, this is simply a routing error I would check in config/routes.rb and check you had a line of code like the following:

 root to: 'statuses#index'

If this is missing then there is not mapping of the URL "/" to any controller action in which case you get the error you see. You can also query rake routes and see if there is a mapping of root directory to any of your contoller actions. You are looking for the prefix column and for a row beginning "root" 

rake routes

This can sometimes get a little overwhelming so you can reduce the output by using grep 

rake routes | grep root
                    root GET    /                   statuses#index       <== This row

or a controller specifier

rake routes CONTROLLER=statuses
     Prefix Verb   URI Pattern                  Controller#Action
   statuses GET    /statuses(.:format)          statuses#index
            POST   /statuses(.:format)          statuses#create
 new_status GET    /statuses/new(.:format)      statuses#new
edit_status GET    /statuses/:id/edit(.:format) statuses#edit
      status GET    /statuses/:id(.:format)      statuses#show
            PATCH  /statuses/:id(.:format)      statuses#update
            PUT    /statuses/:id(.:format)      statuses#update
            DELETE /statuses/:id(.:format)      statuses#destroy
       feed GET    /feed(.:format)              statuses#index
       root GET    /                            statuses#index      <== This row

If your not having any luck with this try putting in the following into your browser - just to get something happening:

http://localhost:3000/statuses

Thanks for the quick response Rich. That was the first time I'd had to deal with a problem so it threw me at first. All sorted thanks to your help.

Cheers
