root_path and root_url undefined

Hi all,

I've just started working on another RoR project after a couple of months
away. I'm having trouble with named routes, specifically root_*

In previous apps I've used root_path and root_url without any problems, but
in this project (2.3.2 - the same as my last project where I used it) it
comes up undefined.

I've double and triple checking my routes.rb, and it all appears fine. I've
defined map.root and removed index.html. I just can't think what could be
causing this continuing problem.

I had upgraded this app to 2.3.5 and thought that might have been the cause.
I googled around for deprecation notices or anything and eventually
regressed rails back to 2.3.2 with no change.

I know I've probably missed something very simple, but it's completely
eluding me right now. Any insights you guys could send my way would be



Not sure what is the issue is, I am running 2.3.4 and it works fine.
I do have he map.root as the first entry although I don't think that
will matter.

Can you send your routes.rb file?

Thanks for the reply Darian, I also have map.root as the first (uncommented) entry.

My entire routes.rb is available at, but please don't laugh at my mess :smiley:

Are you sure you restarted your server after introducing the map.root mapping ?

Thanks & Regards,

Also you try
rake routes
to see all your routes.

"root" appears as the first route in the list, and it looks properly formed:

Can you post the error message and any info that appears in the log?

Thanks for the reply, I will get the information posted as soon as possible.
I'm in hospital right now and have only just got internet access provided.
As soon as I can get someone to turn on my dev machine I will be able to
post the logs.

Oh and no flowers or cards please, everyone is so depressingly cheerful it's
a wonder they are still alive :smiley:



My apologies Rick, I didnt intent to send my reply only to you. Here is a
copy for the list to peruse, including some extra information.

Since my last mail I also tried some of the other named routes I have
defined, and all of them come up undefined as well. There is obviously
something strange going on, and I'm not sure if it's me.

Can you post the error message and any info that appears in the log?

Ok here we go:

Error message and backtrace from the logs can be found here:

1 class PagesController < ApplicationController
2 verify :method => :post, :only => [
3 :update, :create, :destroy, :revert
4 ], :redirect_to => root_path
6 def show

The routes.rb has been pastie'd in a previous post, but I will repeat the
link here for reference (

You can also see the result of "rake routes" here

Please let me know if there is anything else I can provide.

Many thanks



I believe in your controller you want to use:

:redirect_to => 'root_path'

Hi, thanks for the reply. Unfortunately that redirects me literally to

I just tried named routes from inside a view and they work as expected. It's
only when I come to use the in a controller that they fail. I've also
compared this project with a previous one I made that used named routes, and
they appear to be used in exatly the same way.



I think you must have something in your code (plugin perhaps?) that is
mucking with the verify. Here's the environment I'm using to try do
duplicate your problem:

About your application's environment
Ruby version 1.8.7 (powerpc-darwin9.7.0)
RubyGems version 1.3.5
Rack version 1.0
Rails version 2.3.2
Active Record version 2.3.2
Action Pack version 2.3.2
Active Resource version 2.3.2
Action Mailer version 2.3.2
Active Support version 2.3.2
Application root /Users/rick/matt
Environment development
Database adapter sqlite3
Database schema version 20091206142727

I did a 'rails matt' followed by 'script/generate scaffold Page
title:string body:text' just to gin things up. I've also added

map.index '/', :controller => 'pages', :action => 'index'

to my routes.rb and removed public/index.html.

To be successful, my verify line must look like:

class PagesController < ApplicationController
  verify :method => :post,
        :only => [:edit, :destroy, :revert],
        :add_flash => { :notice => 'Cannot do that...'},
        :redirect_to => :index_path


class PagesController < ApplicationController
  verify :method => :post,
        :only => [:edit, :destroy, :revert],
        :add_flash => { :notice => 'Cannot do that...'},
        :redirect_to => 'index_path'

If I use

class PagesController < ApplicationController
  verify :method => :post,
        :only => [:edit, :destroy, :revert],
        :add_flash => { :notice => 'Cannot do that...'},
        :redirect_to => index_path

My app fails on the verify producing:

undefined local variable or method `index_path' for

I would suggest you start a simple test app, like this, and then
incrementally add to it any plugins you need.

Regardless, your use of :redirect_to => root_path (without quotes or
colon) is what is producing the error.

Is your experience the same if you use :redirect_to => 'root_url' ?

How about :redirect_to => {
  :controller => 'pages',
  :action => 'show',
  :name => 'HomePage'

Rick, many thanks for your reply. I believe I have sorted it now. If I use

:redirect_to => :root_url

it does appear to work as I expect. I realise that I wasn't using verify in
my last project, and it seems to take slighly different arguments than

So for verify I will use the symbol :root_url but for redirect_to I will use
the method root_url().

Many thanks for the help with this one, my head hasn't been clear enough to
work it out for myself, I might have to lay off the morphine for a while :smiley:



I use redirect_to root_url

You probably ought to save the morphine for when you're feeling
