Question

I don’t know what is up, but I was experimenting with GSUB then decided I didn’t want to use it anymore so changed my link_to arguments back to:

<%= link_to root_url(@user.username), @user.username %>

Now I keep getting this error:
undefined method `gsub’ for nil:NilClass

and when I remove that whole line from my show file everything is fine.

or if I change it to this:

<%= link_to root_url(:user => @user.username), @user.username %>

It’s like it has been confused some how and thinks I’m still using the gsub method when I’m not. I’ve tested or url helpers such as login, password_reset etc and they all work fine. It seems to only be doing this with root_url.

I also cloned a repo of my site from yesterday before I got this issue and guess what?
Same error..

I’ve never been this frustrated with my programming.

Is there something I can clear? I’ve tried clearing everything inthe tmp folder still no luck.

routes:

Mysite::Application.routes.draw do

  resources :users
  resources :sessions
  resources :passwords


  root :to                   => "users#new"
  match 'success'            => "users#success"
  match 'login'              => "sessions#new"
  match 'logout'             => "sessions#destroy"
  match 'reset_password'     => "passwords#new"
  match 'setup_new_password' => "passwords#edit"
  match ':username'          => "users#show"

end

This should do the trick, as root_url (and root_path) do not have parameters:


<%= link_to @user.username, root_url %>
