问题 I often find myself without knowing what exceptions to rescue when using a specific library of code in Ruby. For instance, I often use HTTParty for any HTTP requests my rails/sinatra app would make. I dug around the code for HTTParty and found a file containing the defined exceptions used. Great! I'll just rescue them when making a request. To test it out, I put in a bogus domain name for the request, but instead of HTTParty::ResponseError exception I expected, I instead get got a SocketError

问题 I've got a Sinatra app that I'm trying to run on Dreamhost that makes use of pony to send email. In order to get the application up and running at the very beginning (before adding pony), I had to gem unpack rack and gem unpack sinatra into the vendor/ directory, so this was my config.ru: require 'vendor/rack/lib/rack' require 'vendor/sinatra/lib/sinatra' set :run, false set :environment, :production set :views, "views" require 'public/myapp.rb' run Sinatra::Application I have already done

问题 I have a small app using omniauth and I'm testing it with LinkedIn provider (omniauth-linkedin). Unfortunately my test environment is behind a proxy. So I need to access linkedin through a proxy. How do I set the proxy address so the request to linkedin will succeed? It does not seem to be obeying the http_proxy settings. 回答1: I figured it out, I think.. ue OmniAuth::Builder do provider :linkedin, "KEY", "SECRET", {:client_options => { :proxy =>\ ENV["HTTP_PROXY"] || ENV["http_proxy"] }} end

问题 I am quite new to Ruby as web platform and learn best by adapting and expanding examples. I like Sinatra and want to use it and Chartkick to display charts. Unfortunately, I'm having trouble getting even the most trivial example running and there seems to be a dearth of full examples (lots of 'one liners'). Here's what I have: require 'sinatra' require 'chartkick' get '/' do '<%= javascript_include_tag "//www.google.com/jsapi", "chartkick" %> <%= pie_chart({"Football" => 10, "Basketball" => 5

问题 I am using this code to enable logging in my Sinatra app: log_file = File.new('my_log_file.log', "a") $stdout.reopen(log_file) $stderr.reopen(log_file) $stdout.sync=true $stderr.sync=true The actual logging is done using: logger.debug("Starting call. Params = #{params.inspect}") It turns out that only INFO or higher level log messages are logged and DEBUG messages are not logged. I am looking for a way to set up the log level to DEBUG. 回答1: I guess there might be a better way, but you can

问题 I'm writing a simple app that takes standard input from the user. As for the email entry, I have it verify if it is in a standard email format and then have it list the problems like this when a new instance is going to be saved: u = User.new u.email = params[:email] u.save if u.save redirect '/' else u.errors.each do |e| puts e end end I know that if it is correct it should return back to the home page. If it is wrong I want it to return to the home page as well, but I want it to return an
