I just completed a reasonably painful Facebook Canvas app integration and wanted to share a couple high-level gotcha's I ran into using the Facebooker2 RoR plugin.
My current environment-- this is the one that finally worked, so my recommendation is to implement using these: ruby: 1.8.7 rails: 2.3.12 Heroku stack: bamboo-ree-1.8.7 If you need to migrate to bamboo be sure and follow the instructions provided on Heroku <http://devcenter.heroku.com/articles/bundler> and not the instructions on the Bundler site. First, of course read the core dev docs at Facebook: - http://developers.facebook.com/docs/guides/canvas/ - http://developers.facebook.com/docs/reference/api/user/ Installing Facebooker2: My biggest issue (aside from migrating stacks on Heroku) was learning to work with a Rack app. For my pre Rails 3 app I made the following modifications to process: - Did not use config.ru file. I'm sure there are a lot of Rack gurus who can add detail to why or why not to run a config.ru file, but my final solution involved removing this file. - Created Facebook.rb in /lib dir - Removed Module::Rack declaration from Facebook.rb - my final version of Facebook.rb contains ONLY the class declaration for Facebook and not the surrounding Module declaration used in the Facebooker2 instructions - Added request = Rack::Request.new(env) to Facebook.rb - After removing Module::Rack from Facebook.rb had to access request directly through Rack obj - Again, ninjas please chime in on how this could have been best-ier practiced... but remember, my solution worked! :) - Add to environment.rb - config.middleware.use "Facebook" directly below: Rails::Initializer.run do |config| - /vendor/plugins/facebooker2/lib/rails/controller.rb at ~ line 56 replaced - user = Mogli::User.new(:id=>userid) - with - user = Mogli::User.find(userid, client) - Finally, tiny issue with ssl was solved by changing settings in my facebook app control panel to point ssl requests to my app via heroku and by deploying the piggback addon <http://devcenter.heroku.com/articles/ssl> I'm sure I've left stuff out and I'm sure examples of real code would help anyone actually attempting this work, so please ping if anyone needs additional assistance my experience might provide. -- You received this message because you are subscribed to the Google Groups "Heroku" group.
