sinatra

问题 I have modular style sinatra app, with the following line near the end, so that it can be run standalone: # ... all code before this omitted run! if __FILE__ == $0 end # This is the end of the file When I run this app with ruby app.rb it works fine, and webrick starts up. However, if I run it instead with bundle exec ruby app.rb I get this error: >bundle exec ruby app.rb C:/Ruby200/lib/ruby/gems/2.0.0/gems/sinatra-1.4.4/lib/sinatra/base.rb:1488:in `start_server': undefined method `run' for

问题 I am a former PHP developer learning Rails and Sinatra. In PHP, every page request loaded all of the required files. If I changed some code and refreshed the page, I could be sure that the code was fresh. In Rails 3, Controller code is fresh on every request. However, if I modify any code in the /lib folder, I need to restart the server so the changes take effect. Why does this happen? Is it something to do with the way Ruby is designed? Is Rails doing some optimizations to avoid reloading

问题 I'm working on a simple API with Sinatra and I have a route like this one: get '/api/v1/invoice/:biller', :provides => [:json] do respond_with invoice( request ) end It works like a charm when I don't send any header params, but when I send: Accept Content-Type Then I got a 404 Not Found error and the classic Sinatra error 'Sinatra doesn't know this ditty' . How can I validate specific header params on Sinatra? Edit This is the actual header (Accept) with a curl example: curl -H "Accept:

问题 I'm trying to show some html in a facebook tab page without success.... I'm new in facebook applications and I do not understand what is happening. I've created a heroku app, to use your SSL, named https://sinatra-dev-test.herokuapp.com, this URL only shows a H1 with a "Teste" string. In my Sinatra Application I have a get route, and a post route that redirects to get. The heroku logs do not show nothing in particular, no one error or warning. Here is a screenshot to my facebook app config:

问题 I have a Sinatra DataMapper app hitting a sqlite3 database that I am attempting to deploy to Heroku. First pass, I included my database file in the git repo. This works, as in the app runs, but production data does not belong in the repository. It doesn't really work though because the database is read-only. I then removed the db file for source control and attempted a heroku db:push sqlite://db/my-app.db . This command yields the following stact trace: my-app/(master) ~ heroku db:push sqlite

问题 I've been wondering this for a while now, but what is the best way to ensure that in a web app (RoR, Sinatra, PHP, anything) that when you are creating links (either generating with a method, or writing in by hand) that they go to the proper place whether you are on the root of a domain or not: http://www.example.com/ or http://www.example.com/this/is/where/the/app/is/ My thoughts are get the end-user to specify a document root somewhere in the config of your app, and use that, however I'm
