Action Controller: Exception caught

Rails
1

I’m getting:

Routing Error

no route found to match “/expenses/” with {:method=>:get}

When pointing the browser to http://localhost:3000/expenses/ as per
the
tutorial at http://developer.apple.com/tools/rubyonrails.html. (No,
I’m not a Mac user.)

Is this due to something I’m doing (code wise) or a configuration of
rails or ruby? Google indicates that it may be due to rails
configuration, but it seems more likely that I’ve made an error given
that I’m learning.

At first I thought there was a problem with the database configuration,
but that seems fine.

My results:

You need to just go to http://localhost:3000. The name of your
application is expenses, that does not mean you need to add /expenses to
the end of your URL. Remove expenses and you should see the rails start
page. Delete index.html from your public folder and you should be good
to go. Then you should be able to continue with your tutorial.

After deleting expenses/public/index.html and going to <http://
localhost:3000/> I get:

Routing Error

no route found to match “/” with {:method=>:get}

Is the tutorial in error? It says:

$ script/server

Then point your web browser at http://localhost:3000/expenses. You
should
see the web page that lets you create new accounts.

Looking for a different tutorial :slight_smile:
