sinatra

问题 I have problem getting my sass work with my haml template.

问题 I am using sinatra and DataMapper to access an sqlite3 database. I always get an nil when calling get(params[:id]) . But when I call get(params[:id].to_i) I can get the right record.

问题 It's really difficult to explain. But basically, I have an amazon instance, and I want to ssh into it and run a local server on it with sinatra. so I would ssh into the amazon instance, git clone my repo, and run ruby config.ru.

It works on a rack app but it doesn't work on the sinatra, I've even

问题 I made a simple Sinatra app to run a homepage. It's already working on my computer. Now I wanted to host it at heroku, but I can't manage it to make it run. I am not really familiar with concepts like "Gemfile" or "Procfile". My ruby app requires Sinatra, haml and sinatra/r18n. My gemfile looks like this: source :rubygems gem 'sinatra' gem 'thin' gem 'sinatra-r18n' gem 'haml' My Procfile looks like this: web: bundle exec ruby app.rb -p $PORT My app.rb starts like this: # app.rb require

问题 I am trying to send an email from a contact form (built in HTML) with the Pony Gem within sinatra, I have followed the docs but something must be missing.

问题 Following my question here. So I am trying to do a smart redirect using this: get "/category/:id/merge" do #... setting @catalog_id and category call env.merge("PATH_INFO" => "/catalog/#{@catalog_id}/category/#{category.id}", "REQUEST_METHOD"=>"PATCH","QUERY_STRING"=>"merge=1") status 200 end But when I look in logs, I see something that is not only frustrating but also completely absurd: # this one is from internal call I, [2013-03-21T15:55:54.382153 #29569] INFO -- : Processing GET /catalog
