В приложении Rails-3.0.10 у меня есть такой маршрут:
match "/" => GithubTrends
, который указывает приложение sinatra в lib / github_trends.rb:
$:.unshift File.dirname(__FILE__)
class GithubTrends < Sinatra::Base
disable :run
set :root, File.dirname(__FILE__) + '/../'
set :cache_enabled, true # production
LANGUAGES = ['ActionScript', 'Ada', 'Arc', 'Asp', 'Assembly', 'Boo', 'C', 'C#', 'C++', 'Clojure', 'CoffeeScript', 'ColdFusion', 'Common Lisp', 'D', 'Delphi', 'Dubi', 'Eiffel', 'Emacs Lisp', 'Erlang', 'F#', 'Factor', 'FORTRAN', 'Go', 'Groovy', 'Haskell', 'HaXe', 'Io', 'Java', 'JavaScript', 'Lua', 'Max/MSP', 'Nu', 'Objective-C', 'Objective-J', 'OCaml', 'ooc', 'Perl', 'PHP', 'Pure Data', 'Python', 'R', 'Racket', 'Ruby', 'Scala', 'Scheme', 'sclang', 'Self', 'Shell', 'SmallTalk', 'SuperCollider', 'Tcl', 'Vala', 'Verilog', 'VHDL', 'VimL', 'Visual Basic', 'XQuery']
CONTEXTS = ['most_watched_today', 'most_watched_this_week', 'most_watched_this_month', 'most_watched_overall', 'most_forked_today', 'most_forked_this_week', 'most_forked_this_month', 'most_forked_overall']
get "/" do
@languages = LANGUAGES
@contexts = CONTEXTS
haml(:index)
end
... но это не работает, получая следующие ошибки:

Первая строка говорит "неинициализированная константа GithubTrends (NameError)" ...
ОБНОВЛЕНИЕ
Я добавил следующее в config / application.rb:
config.autoload_paths += %W(#{config.root}/lib)
config.autoload_paths += Dir["#{config.root}/lib/**/"]
... но теперь я получаю:

UPDATE-2:
запустив sinatra вручную, запустите сервер, но получите, «может быть», ошибку маршрутизации:
lsoave@ubuntu:~/rails/github/gitwatcher$ ruby lib/github_trends.rb
== Sinatra/1.2.6 has taken the stage on 4567 for development with backup from Thin

UPDATE (последнее и рабочее обновление):
config.autoload_paths += %W(#{config.root}/lib)
было недостаточно вмое дело.Я по-прежнему получаю следующую ошибку:
/home/lsoave/.rvm/gems/ruby-1.9.2-p136/gems/railties-3.0.10/lib/rails/application.rb:168:in `call': undefined method `reverse_merge!' for Sinatra::Application:Class (NoMethodError)
... также работает ruby lib/github_trends.rb (запускается вручную в изоляции, как подсказывают hrickards ), работает нормально после некоторой «подрезки», нополучил предыдущую ошибку при запуске через "rails s".
Но было достаточно добавить require File.dirname( __FILE__ ) + "/lib/github_trends" в config.ru файл rails, чтобы все работало нормально!
Это было по предложению Райан Бигг , см. Комментарий № 10:
... проблема в том, что Лука не требует файла, который определяет эту константу, прежде чем он попытается обратиться к ней
... даже если я не совсем понимаю, как один config.autoload_paths один не работал ...
Я хотел бы поблагодарить за устранение неполадок и config.autoload_pathsпредложено hrickards см. комментарии.
Спасибо, luca
