padrino-warden

A Padrino module that provides authentication for your Padrino application through Warden.

Most of the code was adapted from sinatra_warden.

Usage

Currently padrino-warden uses +password+ as default authentication strategy. If you wish to change that consult Warden.

class SampleApp < Padrino::Application
  register Padrino::Warden

  class User
    attr_reader :name
    def initialize(name)
      @name=name
    end

    def self.authenticate(a, b)
      return User.new('john')
    end
  end

  Warden::Strategies.add(:password) do
    def valid?
      params["email"] || params["password"]
    end

    def authenticate!
      u = User.authenticate(params["email"], params["password"])
      u.nil? ? fail!("Could not log in") : success!(u)
    end
  end

  Warden::Manager.serialize_into_session do |user|
    user.id
  end

  Warden::Manager.serialize_from_session do |id|
    User.get(id)
  end
end

Run this to see your new routes:

$ padrino rake routes

You can now login at http://localhost/sessions/login

After login you can fiddle with current_user for anything you need.

Multi Sub-Apps

You UserApp(/user):

register Padrino::Warden

This will mount the sessions controller on it:

/user/sessions/...

You OtherApps:

register Padrino::Warden::Helpers

But you must apply the same options in your UserApp.

Overriding warden manager defaults

class SampleApp < Padrino::Application
  register Padrino::Warden

  Warden::Strategies.add(:token) do
    def valid?
      params["token"]
    end

    def authenticate!
      ...
    end
  end

  set :warden_config do |manager|
    manager.scope_defaults :api, strategies: [:token], store: false
  end
end

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
