问题 I'm starting thin with a parameter set like the following under ubuntu chdir: /var/www/myuser/current rackup: /var/www/myuser/current/config.ru environment: production address: 0.0.0.0 port: 3000 timeout: 30 log: log/thin.log pid: tmp/pids/thin.pid max_conns: 1024 max_persistent_conns: 512 require: [] wait: 30 servers: 3 daemonize: true user: myuser group: myuser And I want to define a set of environment variables for "myuser" so they can be accessible in the rack application I'm deploying in

问题 I'd like to log things from within a middleware that I'm putting into a Rails app, using the app's existing logger. Is there a standard way to do this? Two possibilities that come to mind: the logger is directly accessible in the rack environment the loger can be accessed at app boot time and assigned to the middleware Searching for solutions involving either of these doesn't come up with much. I haven't fully thought through/experimented to see if the order of operations allows either to be

问题 Environment: Ruby: 2.1.2 Rails: 4.1.4 Heroku In our rails app hosted on Heroku, there are times that requests take a long time to execute. It is just 1% of times or less, but we cannot figure out what it is happening. We have newrelic agent installed and it says that it is not request-queuing , it is the transaction itself who takes all that time to execute. However, transaction trace shows this: (this same request most of the times takes only 100ms to be executed) As far as I can tell, the

问题 I have created a custom middleware for rails which will intercept all requests and make sure it's coming from an authorized IP, otherwise it should prompt for a basic http auth user/name password. This is currently what it looks like: require 'net/http' class AuthorizeEnvironment def initialize(app) @app = app end def call(env) if AppConstants.approved_doximity_ips.include?(env["REMOTE_ADDR"]) @app.call(env) elsif authorized?(env) @app.call(env) else [403, {"Content-Type" => "text/html"}, [

问题 I'm developing an application serving large videos only to logged users. To keep these videos private i put them in a private folder inside Rails project and let Rails serve them, instead of using the public folder and excluding requests from apache (to avoid direct linking to them). My action in the controller looks like this: def video respond_to do |format| format.mp4{ send_file File.join([Rails.root, "private/videos", @lesson.link_video1 + ".mp4"]), :disposition => :inline, :stream =>

In which file should I make changes so that it will take the add the file that I want into the cache manifest. I want to include the file in my views folder. 回答1: You need to add it to your routes.rb file. Here is my routes.rb file with a customized manifest.

问题 I'm using a very simple Sinatra app that works well. However, every log message is repeated three times. I can bring that down to two by disabling the Sinatra logging with disable :logging but I still have two. The messages are slightly different, so I gather they are coming from Rack and somewhere else in the stack too. How do I completely disable logging of successful web requests? 回答1: Rack is adding own logging as a middleware try to run rackup -E none This removes one log entry. The

问题 Gemfile file: 'rack', '~> 1.6.0' I am having little trouble in passing the session variables from rspec tests to the Rack middleware. I have gone through many articles on internet but there is no solution which can help me to understand. So basically i want to be able to do this in my middleware class req = Rack::Request.new(env) req.session[:token] But currently req.session[:token] comes as empty from my rspec.
