Deploy on Heroku

You can deploy the app on Heroku by clicking the button below:


If you don't have a Heroku account, you will be prompted to create one.


The following free add-ons are automatically installed as part of set-up. Even though the add-ons are free, you have to verify your account by adding a credit card.

  • PostgreSQL is the database for your application.
  • SendGrid sends emails from your application (e.g. the forgot password email).
  • NewRelic monitors your application performance
  • Cloudinary resizes, crops and then stores the images in your application.

Configure the recover password host redirection:

During setup, you will be prompted to enter a EMAIL_REDIRECT_HOST, used within the emails sent from your application. The value should be

Scale to 2 dynos

First, go to your Heroku account and create an application to be used for the project. When asked for the number of web dynos to be used in your application select 2. There is a small monthly fee associated with having an extra dyno.

For testing purposes, you can choose an application with no extra dynos (this will be free). Please note that sites with no extra dynos "go to sleep" and can be slow to wake up. So, when you are ready to let the public use your site, make sure that your Heroku appliation has at least 2 dynos.

FINAL STEP: Update your username and password via the Content Editor

Your site was installed with a default username and password (these are set in the db/seeds.rb file). Go to your app and login

The default username and password are:


Once you login, use the Admin menu in the navigation to change the email to your email address. Then you will need to change the password to a strong password that only you know.

Development Environment Setup

In most cases you will not need to setup a development environment for this application. The only reason to go through the following steps would be if you wanted to customize your site beyond what you can set with the Content Editor.


To setup the application you will need:

  • PostgreSQL database
  • Ruby 1.9.3-p448
  • Bundler gem
  • Bower

PostgreSQL installation


$ sudo apt-get -y install postgresql

Mac OS X

$ brew install postgresql

Ruby Installation


To install ruby, it is necessary to have rbenv installed. This can be installed following the steps described in rbenv's Github Repository, in the Installation Section.

Ruby 1.9.3-p448

When rbenv is already installed, go to the project's root folder, and run the following command

 $ rbenv install

Bundler gem

In order the manage the project dependencies, it is necessary to have installed bundler.

 $ gem install bundler


To manage the client-side js dependencies, it is necessary to have installed bower. Bower depends on node.js, so if it is not installed yet, install it with nvm, following these instructions: NVM - Installation guide.

Having node.js installed, run the following command to install bower:

npm install -g bower

Development environment

Before running the app, the following steps should be performed.

  • Obtain a copy of the application
  • Create the database user for the application
  • Install the application dependencies
  • Create the database
  • Download the client-side dependecies

Obtain a copy of the application

Clone the code to your computer. The command you type into your shell application (Terminal on the Mac) will be:

$ git clone

This will create a directory named city-72.

Create the database user for the application

createuser -P -s city72

Assign the word city72 as password too.

Linux users should run the above command as postgres user (sudo su postgres).

Install the application dependencies

bundle install

Create the database

bundle exec rake db:setup

Download the client-side dependencies

bower install

Run the application locally

With all the prerequisites and the development environment ready. Just run the app, with the following command:

bundle exec rails s

Open your application on Port 3000

Go to your browser and open
