sinatra

问题 I have a Sinatra app setup where most of the logic is performed inside of various classes, and the post / get routes instantiate those classes and call their methods. I'm thinking about whether putting the post / get route handlers inside of the classes themselves would be a better structure. In any case, I'd like to know if it is possible. So for instance: class Example def say_hello "Hello" end get '/hello' do @message = say_hello end end Without modification to the above, Sinatra will say

问题 Right now, I do a get '/' do set :base_url, "#{request.env['rack.url_scheme']}://#{request.env['HTTP_HOST']}" # ... haml :index end to be able to use options.base_url in the HAML index.haml. But I am sure there is a far better, DRY, way of doing this. Yet I cannot see, nor find it. (I am new to Sinatra :)) Somehow, outside of get , I don't have request.env available, or so it seems. So putting it in an include did not work. How do you get your base url? 回答1: A couple things. set is a class

问题 I want to serve static HTML pages using nginx . Then, I will use jQuery to update DIVs, SPANs, etc via AJAX calls from a Padrino server. I like creating my web pages in HAML because it's easier but in production, I don't want to serve HAML templates. Just raw, HTML at the speed of nginx. Is there an easy way to do this? What would be ideal would be a service that automatically renders HAML, partials, etc into the public folder that nginx could serve. 回答1: Simple, add padrino-cache to your app

问题 I'm trying to set up and run the Extreme Startup coding dojo on my Windows machine. When I try to access the front page on http://localhost:3000, I get this error: application error Errno::ENOENT at / No such file or directory @ rb_sysopen - c:/Users/mark/Desktop/extreme_startup/lib/extreme_startup/views/leaderboard.haml file: template.rb location: initialize line: 210 BACKTRACE (expand) JUMP TO: GET POST COOKIES ENV c:/Users/mark/Desktop/extreme_startup/lib/extreme_startup/web_server.rb in

问题 I'm testing a Sinatra application, which is using DataMapper, with RSpec. The following code: it "should update the item's title" do lambda do post "/hello/edit", :params => { :title => 'goodbye', :body => 'goodbye world' } end.should change(Snippet, :title).from('hello').to('goodbye') end Results in this error: title should have initially been "hello", but was #<DataMapper::Property::String @model=Snippet @name=:title> I can of course hack this by removing the lambda and only checking if:

问题 While loading a Thin webserver for a sinatra app I keep getting Unable to load the EventMachine C extension; To use the pure-ruby reactor, require em/pure_ruby'<path>/vendor/bundle/ruby/1.9.1/gems/eventmachine-1.0.0.rc.4/lib/eventmachine.rb:8:in `require': cannot load such file -- rubyeventmachine (LoadError) from <path>/vendor/bundle/ruby/1.9.1/gems/eventmachine-1.0.0.rc.4/lib/eventmachine.rb:8:in `<top (required)>' from <path>/vendor/bundle/ruby/1.9.1/gems/thin-1.5.0/lib/thin.rb:7:in

问题 I am trying to test a ruby authentication app using minitest and webrat but get errors. Tests like visit '/' fail with an error Status 200 expected but was 404. Tests containing code like fill_in :email, :with => "first@company.com" fail with error Could not find field: :email . I read several sinatra, testing and webrat documents and forums. Some of them were old and suggested stuff like Sinatra::Default, but github.com/brynary/webrat/wiki/sinatra, Building a Sinatra App Driven By Webrat

问题 Trying to get Sinatra setup on Ubuntu 12.04. I have RVM installed, and I think I have installed all dependencies (listed below). I found another SO post (here) that indicated I don't have libssl-dev installed, but it looks like I do. When I run: sudo gem install sinatra I get: ERROR: While executing gem ... (NameError) uninitialized constant Gem::RemoteFetcher::OpenSSL rvm req installs: sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev

问题 I have a sinatra web application and a C++ library that I can 'require' in sinatra (ruby) using bindings created by swig. I also have a second -very similar- library, in which the function names are partially the same as in the first one. When I require them both, the one that is loaded first 'wins', i.e. calls to the ambiguous function names are always mapped to this library. The reason is that 'require' does only load stuff that is not already loaded, whereas 'load' reloads no matter what.

问题 I am running Ubuntu 10.04 on a linode trying to get sinatra, passenger, nginx, and rvm to all play nice with Ruby 1.9.2. I'm running into an issue with gems though: ~/.rvm/gems/ruby-1.9.2-p290/gems$ ls returns daemon_controller-0.2.6 fastthread-1.0.7 passenger-3.0.9 rack-1.3.2 rake-0.9.2 and gem list returns *** LOCAL GEMS *** rack (1.3.2) rake (0.9.2) sinatra (1.2.6) tilt (1.3.3) What is odd to me is that they aren't the same. And sinatra is missing from the .rvm gems. When I go to my
