## Documentation
- [Ruby on Rails Quickstart](https://auth0.com/docs/quickstart/webapp/rails)
- [Sample projects](https://github.com/auth0-samples/auth0-rubyonrails-sample)
- [API Reference](https://www.rubydoc.info/gems/omniauth-auth0)
## Getting started
### Installation
Add the following line to your `Gemfile`:
```ruby
gem 'omniauth-auth0'
```
If you're using this strategy with Rails, also add the following for CSRF protection:
```ruby
gem 'omniauth-rails_csrf_protection'
```
Then install:
```bash
$ bundle install
```
See our [contributing guide](CONTRIBUTING.md) for information on local installation for development.
## Configure the SDK
Adding the SDK to your Rails app requires a few steps:
- [Create the configuration file](#create-the-configuration-file)
- [Create the initializer](#create-the-initializer)
- [Create the callback controller](#create-the-callback-controller)
- [Add routes](#add-routes)
### Create the configuration file
Create the file `./config/auth0.yml` within your application directory with the following content:
```yml
development:
auth0_domain:
auth0_client_id:
auth0_client_secret:
```
### Create the initializer
Create a new Ruby file in `./config/initializers/auth0.rb` to configure the OmniAuth middleware:
```ruby
AUTH0_CONFIG = Rails.application.config_for(:auth0)
Rails.application.config.middleware.use OmniAuth::Builder do
provider(
:auth0,
AUTH0_CONFIG['auth0_client_id'],
AUTH0_CONFIG['auth0_client_secret'],
AUTH0_CONFIG['auth0_domain'],
callback_path: '/auth/auth0/callback',
authorize_params: {
scope: 'openid profile'
}
)
end
```
### Create the callback controller
Create a new controller `./app/controllers/auth0_controller.rb` to handle the callback from Auth0.
> You can also run `rails generate controller auth0 callback failure logout --skip-assets --skip-helper --skip-routes --skip-template-engine` to scaffold this controller for you.
```ruby
# ./app/controllers/auth0_controller.rb
class Auth0Controller < ApplicationController
def callback
# OmniAuth stores the information returned from Auth0 and the IdP in request.env['omniauth.auth'].
# In this code, you will pull the raw_info supplied from the id_token and assign it to the session.
# Refer to https://github.com/auth0/omniauth-auth0/blob/master/EXAMPLES.md#example-of-the-resulting-authentication-hash for complete information on 'omniauth.auth' contents.
auth_info = request.env['omniauth.auth']
session[:userinfo] = auth_info['extra']['raw_info']
# Redirect to the URL you want after successful auth
redirect_to '/dashboard'
end
def failure
# Handles failed authentication -- Show a failure page (you can also handle with a redirect)
@error_msg = request.params['message']
end
def logout
# you will finish this in a later step
end
end
```
### Add routes
Finally, add the following routes to your `./config/routes.rb` file:
```ruby
Rails.application.routes.draw do
# ..
get '/auth/auth0/callback' => 'auth0#callback'
get '/auth/failure' => 'auth0#failure'
get '/auth/logout' => 'auth0#logout'
end
```
## Logging in
To redirect your users to Auth0 for authentication, redirect your users to the `/auth/auth0` endpoint of your app. One way to do this is to use a link or button on a page:
```html
<%= button_to 'Login', '/auth/auth0', method: :post %>
```
