Peeking at the Rails module using pry reveals that console invocations can be detected like this: Rails.const_defined? ‘Console’ And server invocations like this: Rails.const_defined? ‘Server’
Use a sinatra before handler: before do request.body.rewind @request_payload = JSON.parse request.body.read end this will expose it to the current request handler. If you want it exposed to all handlers, put it in a superclass and extend that class in your handlers.
As of Rails 3.2, Rack middleware belongs in the app/middleware directory. It works “out-of-the-box” without any explicit require statements. Quick example: I’m using a middleware class called CanonicalHost which is implemented in app/middleware/canonical_host.rb. I’ve added the following line to production.rb (note that the middleware class is explicitly given, rather than as a quoted string, which … Read more
Sinatra 1.3 will ship with such a logger object, exactly usable as above. You can use edge Sinatra as described in “The Bleeding Edge”. Won’t be that long until we’ll release 1.3, I guess. To use it with Sinatra 1.2, do something like this: require ‘sinatra’ use Rack::Logger helpers do def logger request.logger end end
Make sure you are pushing a repo that contains a proper supported app ( Rails, Django etc.) and you are not just pushing some random repo to test it out. Newbie in Heroku: Error when push my app to Heroku If that is not the case and you are pushing what you think is a … Read more
You could use two Procfiles (e.g. Procfile and Procfile.dev) and use foremans -f option to select a different one to use in dev: In dev (Procfile.dev contains your shotgun web process): foreman start -f Procfile.dev In production, foreman start will pick up the normal Procfile. Alternatively you could create a bin directory in your app … Read more
Ah, I just stumbled into this exact problem. As it turns out, looping (or any sort of seeking, for that matter) in <video> elements on Chrome only works if the video file was served up by a server that understands partial content requests. i.e. the server needs to honor requests that contain a “Range” header … Read more
request.ip returns the client ip even if that client is a proxy. request.remote_ip is smarter and gets the actual client ip. This can only be done if the all the proxies along the way set the X-Forwarded-For header.
Rack as Design Rack middleware is more than “a way to filter a request and response” – it’s an implementation of the pipeline design pattern for web servers using Rack. It very cleanly separates out the different stages of processing a request – separation of concerns being a key goal of all well designed software … Read more
