i am trying to create an app with angular and rails.as a first step i am
trying my controller to give json response , in which i am failing with
the below error

Completed 406 Not Acceptable in 26.0ms

my controller-------

class TodosController < ApplicationController
respond_to :json

def index
#respond_with :@todo
@todo=Todo.all
respond_to do |format|
format.json { render :json => @todo}

end
end
end

routes.rb------

resources :todos

gemfile--------

source ‘https://rubygems.org

gem ‘rails’, ‘3.2.17’

Bundle edge Rails instead:

gem ‘activerecord-jdbcsqlite3-adapter’
gem ‘jruby-openssl’

group :development, :test do
gem ‘ffaker’
gem ‘factory_girl_rails’
gem ‘rspec-rails’
gem ‘shoulda’
gem ‘shoulda-matchers’
end

Gems used only for assets and not required

in production environments by default.

group :assets do
gem ‘sass-rails’, ‘~> 3.2.3’
gem ‘coffee-rails’, ‘~> 3.2.1’

See https://github.com/sstephenson/execjs#readme for more supported
