CloudFoundry 504 Gateway Time-out - ruby-on-rails-3

Question

I have tried to push a simple rails 3.2.3 application with mongo_mapper to cloudfoundry, but I am getting 504 Gateway Time-out. The application ran fine on localhost. I provided additional information below. Please could you provide me assistance to resolve this issue?
To create and push application I typed:
rails new myapp -skip-active-record
scaffold massage content:string --skip-migration --orm mongo_mapper
bundle update
bundle install
bundle package
vmc push myapp --runtime ruby19
Here is the Gemfile:
Source 'http://rubygems.org'
gem rails', '3.2.3
gem mongo_mapper
gem bson_ext
end
Here is the controller:
class MessagesController < ApplicationController
def index
#messages = Message.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: #messages }
end
end
def show
#message = Message.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #message }
end
end
def new
#message = Message.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: #message }
end
end
def edit
#message = Message.find(params[:id])
end
def create
#message = Message.new(params[:message])
respond_to do |format|
if #message.save
format.html { redirect_to #message, notice: 'Message was successfully created.' }
format.json { render json: #message, status: :created, location: #message }
else
format.html { render action: "new" }
format.json { render json: #message.errors, status: :unprocessable_entity }
end
end
end
def update
#message = Message.find(params[:id])
respond_to do |format|
if #message.update_attributes(params[:message])
format.html { redirect_to #message, notice: 'Message was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #message.errors, status: :unprocessable_entity }
end
end
end
def destroy
#message = Message.find(params[:id])
#message.destroy
respond_to do |format|
format.html { redirect_to messages_url }
format.json { head :no_content }
end
end
end
Here is the modle:
class Message
include MongoMapper::Document
key :content, String
end
Here is the index view
<h1>Listing messages</h1>
<table>
<tr>
<th>Content</th>
</tr>
<% #messages.each do |message| %>
<tr>
<td><%= message.content %></td>
<td><%= link_to 'Show', message %></td>
<td><%= link_to 'Edit', edit_message_path(message) %></td>
<td><%= link_to 'Destroy', message, :confirm => 'Are you sure?', method: :delete %></td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New Message', new_message_path %>
Here is config/locales/mongo.yml
defaults: &defaults
host: 127.0.0.1
port: 27017
development:
<<: *defaults
database: proj815_development
test:
<<: *defaults

# set these environment variables on your prod server
production:
host: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-1.8'].first['credentials']['hostname'] rescue 'localhost'%>
port: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-1.8'].first['credentials']['port'] rescue '27017'%>
database: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-1.8'].first['credentials']['db'] rescue 'proj815' %>
username: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-1.8'].first['credentials']['username'] rescue ''%>
password: <%= JSON.parse( ENV['VCAP_SERVICES'] )['mongodb-1.8'].first['credentials']['password'] rescue ''%>

Normally this happens because your application is too large to upload, if you can reduce the size of your application, you should be fine.
