I have no idea what this the internal working of rails is as this error seem to be some problem coming from 'mapping.rb'.
The following it my routes.rb
TestApp::Application.routes.draw do
root 'dunbs' => 'dunbs#index'
end
Your syntax for defining a root route is incorrect, it should be either root to: 'dunbs#index' or root 'dunbs#index'.
See http://guides.rubyonrails.org/routing.html#using-root for more details.

I have used Devise a million times, but I have never had this issue. I have placed the gem in my gem file. I did 'bundle install' then I typed ' rails generate devise:install' and I get this error:

Can someone help? I can't seem to get past this basic setup stage.
Your error shows you added devise_for :user in routes.rb when you haven't set it up yet, as shown here:
from /Users/johnseabolt/Desktop/2. Projects/ReactBlog/config/routes.rb:2:in `<top (required)>'
Remove devise_for :user from routes.rb, run the install generator, then add devise_for :user again if it worked out.
I am able to generate a url and associated web page with the help of the rails generate controller static_pages about. So the url would be something like this www.bla.com/static_pages/about'. Now I want to generate this urlbla.com/help` without the use of generate,
I added a route in routes.rb like this
get 'help'
Then I added an action in application_controller.rb like this
def hello
render text: "Hello"
end
Then when started the server, I get the following error

Missing :controller key on routes definition, please check your
routes. (ArgumentError)
As the error states, you need to specify controller and action matching to the route. The below should work.
get "help", to: 'static_pages#about', as: 'help'
^^^^^^ ^^^^
controller action
Also, I suggest you to follow these Guides for clear understanding on how to define the routes.
I followed the steps on https://github.com/plataformatec/devise to install devise.

Okay, I figured out the problem. I guess because I previous installed devise and tried to reinstall a new version. However, devise automatically created some models for the app. I deleted those created folders/files and rerun rails generate devise:install and it worked.
When I try to run my rails server I get the following error (Important note: I have just pulled my code from Github to Nitrous.Io, and was starting to work on the application):

Looks like your database hasn't yet been created.
The most likely solution would be to run rake db:migrate if you're using sqlite, though if you're using Postgres or Mysql on Nitrous, you'll need to install them first. There is a guide to what's available here http://help.nitrous.io/categories/databases/
I included 'backbone-on-rails' in my Gemfile, did bundle install, and then did
rails generate backbone:install --javascript
And I got the error below. I'm using rails 3.2.8 and ruby 193. Can anyone explain what the problem might be?
If I can't get the gem to work, does anyone know where I should include _underscore and backbone in a Rails application?

It had nothing to do with backbone-on-rails. I had an error in the route that was defined in routes.rb
