Devise iOS Rails Backend

Gem that updates devise to work with external clients. Specially created to work with devise for iOS.

It currently implements authentication only with a "simple token authentication".

Requirements

Name	Version
Ruby	2.1.5
Rails	4.1.8
Devise
Simple Token Authentication
Active Model Serializers

Setup

With a working devise environment, the only thing you need to do is:

• add gem to the Gemfile gem 'devise-ios-rails'
• run bundler to install the gem bundle install
• setup devise like you would normally do (check the installation guide)
• in your routes change devise_for ModelName with devise_ios_rails_for ModelName (ModelName is usually User)
• authentication is handled by user token which is generated for each user during the registration process.

To make it work you need to run migration that adds authentication_token column to your Devise model. If your ModelName is User then the migration should look like this:

class AddUniqueTokenToUser < ActiveRecord::Migration
  def change
    add_column :users, :authentication_token, :string
    add_index :users, :authentication_token, unique: true
  end
end

Don't forget about rake db:migrate.

-To protect actions to only registered users, add acts_as_token_authentication_handler_for User in your controller:

class SecretSpacesController < ApplicationController
  acts_as_token_authentication_handler_for User
end

• If you want to skip authentication for some actions add skip_before_filter :authenticate_user_from_token!, only: [:action] in your controller

class SecretSpacesController < ApplicationController
  acts_as_token_authentication_handler_for User
  skip_before_filter :authenticate_user_from_token!, only: [:new]
end

Example app

• Rails with devise and Simple Authentication Token authentication

Testing

In order to run tests, first you need setup the gem locally.

• clone the repo to your machine git clone https://github.com/netguru/devise-ios-rails.git
• go inside gems directory cd devise-ios-rails and run bundle command bundle install
• now you need to setup your environment variables. You can simply just copy over .env.sample to .env. It should look more or less like this:

DOMAIN_NAME='localhost:3000'
DOMAIN_URL='http://localhost:3000'
SECRET_KEY_BASE='a_very_long_string'
DEFAULT_SENDER='[email protected]'

then you can run your tests by typing rspec.
