This application adds some nice helpers on-top of the base Warden Rack layer. It aims to make Warden easier to use in Rails-based environments without something as heavy-weight as devise.
Add this line to your application's Gemfile:
gem 'rails_warden'And then execute
$ bundle
Or install it yourself as:
$ gem install rails_warden
Create a new Rails initializer to inject RailsWarden into the Rails middleware stack:
# config/initializers/warden.rb
Rails.configuration.middleware.use RailsWarden::Manager do |manager|
manager.failure_app = Proc.new { |_env|
['401', {'Content-Type' => 'application/json'}, { error: 'Unauthorized', code: 401 }]
}
manager.default_strategies :password # needs to be defined
# Optional Settings (see Warden wiki)
# manager.scope_defaults :admin, strategies: [:password]
# manager.default_scope = :admin # optional default scope
# manager.intercept_401 = false # Warden will intercept 401 responses, which can cause conflicts
endIf you want to customize the Session serializer (optional), add the following to the intializer:
class Warden::SessionSerializer
def serialize(record)
[record.class.name, record.id]
end
def deserialize(keys)
klass, id = keys
klass.find_by(id: id)
end
endThe next step is to configure warden with some authentication strategies. Check out the warden wiki for that.
RailsWarden ships with a helpful set of methods and helpers for use inside of ActionController.
To use them, just include them inside your base controller.
class ApplicationController < ActionController::Base
include RailsWarden::Authentication
