Devise with Sinatra

Question

Does anyone had installed Devise gem with Sinatra?

Devise is based on Warden and so it should work on Sinatra, I couldn\'t find any related info about how to implement i

Answer 1

I was able to get it working. There were a few main aspects:

1. Get Devise working with Rails (Devise is a Rails app, won't work without it)
2. Setup the mapping (route) on Rack level to support both Rails and Sinatra
3. Share the sessions between Rails and Sinatra
4. Setup Warden and make it available to Sinatra

Here is most relevant part of code from /config.ru:

    #

    # ...

    # Rest with Rails
    map "/" do
      run MyApp::Application
    end

    # Anything urls starting with /slim will go to Sinatra
    map "/slim" do

      # make sure :key and :secret be in-sync with initializers/secret_store.rb initializers/secret_token.rb
      use Rack::Session::Cookie, :key => '<< see, initializers/secret_store.rb >>', :secret => '<< copy from initializers/secret_token.rb >>'

      # Point Warden to the Sinatra App
      use Warden::Manager do |manager|
        manager.failure_app = AppMain
        manager.default_scope = Devise.default_scope
      end

      # Borrowed from https://gist.github.com/217362
      Warden::Manager.before_failure do |env, opts|
        env['REQUEST_METHOD'] = "POST"
      end

      run AppMain
    end
