Question

I use Sinatra modular style, i don’t know what going bad. I serach google but didn’t find anything

require 'sinatra/base'

class App < Sinatra::Base

  get '/' do
    haml '%h1 Test'
  end

end

run App

And a see test.rb:12:in <main>': undefined methodrun’ for main:Object (NoMethodError)
What going wrong?

Answer 1

did you run it via ruby -rubygems hi.rb (assuming this code is in hi.rb). If so, you don’t need run App. Unless you are running it through another framework built on/with Sinatra.

Also might want to include haml…

You have a config.ru:

# config.ru
require 'my_app'
run MyApp

and a my_app.rb:

# my_app.rb
require 'sinatra/base'
require 'haml'

class MyApp < Sinatra::Base

get('/') { haml '%h1 Test' }

  # start the server if ruby file executed directly
  run! if app_file == $0
end

then in the folder where the my_app.rb is run this to start the app on localhost:4657:

rackup -p 4567
