Rails + Yelp

This is a sample Rails application using the Ruby gem. To check it out in action, visit http://rails-yelp.herokuapp.com/.

Usage

The key take away here is that you'll want to place an initializer inside of config/initializers that set's up the keys for the gem.

# inside of config/initializers/yelp.rb

Yelp.client.configure do |config|
  config.consumer_key = YOUR_CONSUMER_KEY
  config.consumer_secret = YOUR_CONSUMER_SECRET
  config.token = YOUR_TOKEN
  config.token_secret = YOUR_TOKEN_SECRET
end

Now you can use the a pre-initialized client anywhere in the app:

# inside of HomeController
# app/controllers/home_controller.rb

class HomeController < ApplicationController
  # ...

  def search
    parameters = { term: params[:term], limit: 16 }
    render json: Yelp.client.search('San Francisco', parameters)
  end
end

The client is a singleton so that it's only initialized the first time you call it. The same client is used for every subsequent request made throughout the application.

Using this example application

This Rails application was made as an example to show an integration with the Yelp gem/API. For the most part it's ready to go to deploy on Heroku but a few things have been changed.

API Keys

API keys are set and used from environment variables.

Yelp

You'll need to register an account and get API keys from the developer site.

Google Maps

You can get a Google Maps key from the Google Developer Console. Enable the Geocoding API and Google Maps Javascript API v3 to get the map working.

`config/database.yml`

The database file is fairly empty and is set to work with a clean/default PostgreSQL installation. If you're looking to configure it to your system or use a different adapter we recommend looking at the Ruby on Rails guide to configuring the database for more information.

`config/secrets.yml`

Every rails application employs a secret key to verify signed cookies. To keep people from using the same secret keys we've removed them here. You should generate new ones with rake secret before starting development.
