I have a nanoc site (so, all static pages) that I'd like to test with unicorn.
The idea behind this is to host this site on heroku then.
The structure is then a rack application.
I have added a config.ru file like:
require 'rubygems'
require 'rack'
require 'rack-rewrite'
require 'rack/contrib'
use Rack::Rewrite do
rewrite '/','/output/index.html'
end
use Rack::Static, :urls => ['/'], :root => "output"
(all my static resources are located in the output directory)
When I run unicorn I got the following error message:
NoMethodError at /output/index.html
undefined method `to_i' for #<Rack::Static:0x10165ee18>
I do not really understand what I am missing here :(
Any idea ?
Thanks and regards,
Luc
with this config.ru, it works :)
require 'rubygems'
require 'rack'
require 'rack/contrib'
require 'rack-rewrite'
require 'mime/types'
use Rack::Deflater
use Rack::ETag
module ::Rack
class TryStatic < Static
def initialize(app, options)
super
#try = ([''] + Array(options.delete(:try)) + [''])
end
def call(env)
#next = 0
while #next < #try.size && 404 == (resp = super(try_next(env)))[0]
#next += 1
end
404 == resp[0] ? #app.call : resp
end
private
def try_next(env)
env.merge('PATH_INFO' => env['PATH_INFO'] + #try[#next])
end
end
end
use Rack::TryStatic,
:root => "output", # static files root dir
:urls => %w[/], # match all requests
:try => ['.html', 'index.html', '/index.html'] # try these postfixes sequentially
errorFile='output/404.html'
run lambda { [404, {
"Last-Modified" => File.mtime(errorFile).httpdate,
"Content-Type" => "text/html",
"Content-Length" => File.size(errorFile).to_s
}, File.read(errorFile)] }

I have a file called app.rb that runs a server when I run it on my local machine. I would like to deploy app.rb to Heroku so the server will run on Heroku. I think I need to make root in routes.rb point it to. How do I do this?
this is the config.ru:
require_relative 'config/environment'
require '/.app.rb'
run Rails.application
run Sinatra::Application
This is the web server code in app.rb, from codepath guides (https://guides.codepath.com/android/Google-Cloud-Messaging#step-3-setup-web-server):
require 'sinatra'
require 'rest-client'
require 'sequel'
# Create a SQLite3 database
DB = Sequel.connect('sqlite://gcm-test.db')
# Create a Device table if it doesn't exist
DB.create_table? :Device do
primary_key :reg_id
String :user_id
String :reg_token
String :os, :default => 'android'
end
Device = DB[:Device] # create the dataset
# Registration endpoint mapping reg_token to user_id
# POST /register?reg_token=abc&user_id=123
post '/register' do
if Device.filter(:reg_token => params[:reg_token]).count == 0
device = Device.insert(:reg_token => params[:reg_token], :user_id => params[:user_id], :os => 'android')
end
end
# Ennpoint for sending a message to a user
# POST /send?user_id=123&title=hello&body=message
post '/send' do
# Find devices with the corresponding reg_tokens
reg_tokens = Device.filter(:user_id => params[:user_id]).map(:reg_token).to_a
if reg_tokens.count != 0
send_gcm_message(params[:title], params[:body], reg_tokens)
end
end
# Sending logic
# send_gcm_message(["abc", "cdf"])
def send_gcm_message(title, body, reg_tokens)
# Construct JSON payload
post_args = {
# :to field can also be used if there is only 1 reg token to send
:registration_ids => reg_tokens,
:data => {
:title => title,
:body => body,
:anything => "foobar"
}
}
# Send the request with JSON args and headers
RestClient.post 'https://gcm-http.googleapis.com/gcm/send', post_args.to_json,
:Authorization => 'key=' + AUTHORIZE_KEY, :content_type => :json, :accept => :json
end
This is the procfile:
web: bundle exec puma -C config/puma.rb
when I follow the getting started with Ruby on Heroku example, I can see the example webpage. However, if I edit the config.ru file with 'run Sinatra::Application', and deploy to heroku, it is not able to show the example webpage anymore, and just says "Not Found"
require '/.app.rb'
This should be ./app.rb instead.
I am newbie in ruby and working on making performance automation framework using using 'ruby-jmeter' gem (provided by flood.io)

This is the Sinatra code that I wrote. All gems exist, the ruby files compiles perfectly but when i go to localhost:4567/ the sinatra app doesnt run. It takes me to the 'Sinatra doesnt know this ditty' page. What mistake am i making here? Is it a syntax issue? I've posted the main ruby file's code here others are just haml files thats all.

As you have a modular app do you need to require "sinatra/base" rather than "sinatra"? See here
See Serving a Modular App and add the line run! if app_file == $0 at the end of the class. Also see DavB's answer.
I'm writing a Sinatra Rack App and I want to use Warden for authentication. I'm using heroku's toolbelt so I use foreman to run my app. I've found some code that's presumably supposed to get this working. Unfortunately, when I attempt to actually access the Warden env object, it is nil.
I've attempted to use the sinatra_warden gem, but it also has its own bugs (might be related to this one).
config.ru:
require './web.rb'
use Rack::Static, :urls => ["/css", "/img", "/js"], :root => "public"
run MyApp
web.rb:
require 'sinatra'
require 'warden'
require 'data_mapper'
require './config/datamapper.rb'
require './config/warden.rb' # I've tried this inside of MyApp, still didn't work
class MyApp < Sinatra::Base
get '/test' do
env['warden'].authenticate! # env['warden'] is nil :(
end
end
config/warden.rb:
use Rack::Session::Cookie, :secret => ENV['SESSION_SECRET']
use Warden::Manager do |manager|
manager.default_strategies :password
manager.failure_app = MyApp.new
end
Warden::Manager.serialize_into_session { |user| user.id }
Warden::Manager.serialize_from_session { |id| User.get(id) }
Warden::Manager.before_failure do |env,opts|
# Sinatra is very sensitive to the request method
# since authentication could fail on any type of method, we need
# to set it for the failure app so it is routed to the correct block
env['REQUEST_METHOD'] = "POST"
end
Warden::Strategies.add(:password) do
def valid?
params["email"] || params["password"]
end
def authenticate!
u = User.authenticate(params["email"], params["password"])
u.nil? ? fail!("Could not log in") : success!(u)
end
end
Versions:
Sinatra: 1.1.0
Warden: 1.2.1
Rack: 1.4.1
Ruby: 1.9.3p194
Foreman: 0.60.0
Any ideas how to use Warden the set up I've described?
(P.S. Out of curiosity, what exactly is the env variable?)
Rack internally uses the class Rack::Builder to parse your config.ru file and wrap directives to build up the middleware components.
I believe your builder calls to use in config/warden.rb are getting ignored. It may work to remove the directives from that file and add them to the middleware stack in config.ru:
require './web.rb'
use Rack::Session::Cookie, :secret => ENV['SESSION_SECRET']
use Warden::Manager do |manager|
manager.default_strategies :password
manager.failure_app = MyApp.new
end
use Rack::Static, :urls => ["/css", "/img", "/js"], :root => "public"
run MyApp
Put a link to your config/warden in your config.ru
require File.dirname(__FILE__) + '/config/warden'
Read the warden readme. Or look right in the lib/warden.rb
I put
Warden.test_mode!
in place of the env call at the /test path and get a nice blank page at
http://localhost:9292/test
Some bloggers have stated that there isn't a lot of documentation for warden but I disagree. There is a whole wiki. see https://github.com/hassox/warden/wiki
Take it slow and find out how to use middleware in Rack. Here's a very good article https://blog.engineyard.com/2015/understanding-rack-apps-and-middleware
I think maybe you might want to start out with tests as I found a good example and you could use it with your app.
ENV['RACK_ENV'] = 'test'
require 'test/unit'
require 'rack/test'
require File.dirname(__FILE__) + '/web'
class AuthenticationTest < Test::Unit::TestCase
include Rack::Test::Methods
def app
WardenTest #MyApp
end
def test_without_authentication
get '/protected'
assert_equal 401, last_response.status
end
def test_with_bad_credentials
authorize 'bad', 'boy'
get '/protected'
assert_equal 401, last_response.status
end
def test_with_proper_credentials
authorize 'admin', 'admin'
get '/protected'
assert_equal 200, last_response.status
assert_equal "You're welcome, authenticated client", last_response.body
end
end
Then a few routes added to your app.
helpers do
def protected!
return if authorized?
headers['WWW-Authenticate'] = 'Basic realm="Restricted Area"'
halt 401, "Not authorized\n"
end
def authorized?
#auth ||= Rack::Auth::Basic::Request.new(request.env)
#auth.provided? and #auth.basic? and #auth.credentials and
#auth.credentials == ['admin', 'admin']
end
end
get '/' do
"Everybody can see this page"
end
get '/protected' do
protected!
"You're welcome, authenticated client"
end
In my experience working with Ruby, it's always a good idea to start out with tests for any new project. I often test little pieces first though just to gain an understanding of how they work.
Once you get a better understanding of Rack, especially Rack::Builder, you can use
map '/test' do
...all the middleware needed
run App
end
and try out different configurations to see which ones work best for your needs as I'm doing while I write this.
Enjoy! ;-)
I'm trying to get some information from this tutorial: http://m.onkey.org/2008/11/18/ruby-on-rack-2-rack-builder
basically I want to have a file config.ru that tell rack to read the current directory so I can access all the files just like a simple apache server and also read the default root with the index.html file...is there any way to do it?
my current config.ru looks like this:
run Rack::Directory.new('')
#this would read the directory but it doesn't set the root to index.html
map '/' do
file = File.read('index.html')
run Proc.new {|env| [200, {'Content-Type' => 'text/html'}, file] }
end
#using this reads the index.html mapped as the root but ignores the other files in the directory
So I don't know how to proceed from here...
I've also tried this following the tutorials example but thin doesn't starts properly.
builder = Rack::Builder.new do
run Rack::Directory.new('')
map '/' do
file = File.read('index.html')
run Proc.new {|env| [200, {'Content-Type' => 'text/html'}, file] }
end
end
Rack::Handler::Thin.run builder, :port => 3000
Thanks in advance
I think that you are missing the the rackup command. Here is how it is used:
rackup config.ru
This is going to run your rack app on port 9292 using webrick. You can read "rackup --help" for more info how you can change these defaults.
About the app that you want to create. Here is how I think it should look like:
# This is the root of our app
#root = File.expand_path(File.dirname(__FILE__))
run Proc.new { |env|
# Extract the requested path from the request
path = Rack::Utils.unescape(env['PATH_INFO'])
index_file = #root + "#{path}/index.html"
if File.exists?(index_file)
# Return the index
[200, {'Content-Type' => 'text/html'}, File.read(index_file)]
# NOTE: using Ruby >= 1.9, third argument needs to respond to :each
# [200, {'Content-Type' => 'text/html'}, [File.read(index_file)]]
else
# Pass the request to the directory app
Rack::Directory.new(#root).call(env)
end
}
I ended up on this page looking for a one liner...
If all you want is to serve the current directory for a few one-off tasks, this is all you need:
ruby -run -e httpd . -p 5000
Details on how it works: http://www.benjaminoakes.com/2013/09/13/ruby-simple-http-server-minimalist-rake/
You can do this using Rack::Static
map "/foo" do
use Rack::Static,
:urls => [""], :root => File.expand_path('bar'), :index => 'index.html'
run lambda {|*|}
end
For me, using Ruby 2.0 and Rack 1.5.2, sinm solution worked for serving the index page (both as default page for root and loaded explicitly), but for other files I obtained errors similar to the following:
Rack::Lint::LintError: Status must be >=100 seen as integer
I combined sinm solution with this SO answer and the snippet found on Heroku documentation to obtain the desired behavior (assuming that the entire site is contained in a folder called public):
use Rack::Static,
:urls => ["/images", "/js", "/css"],
:root => "public",
:index => 'index.html'
run Rack::File.new("public")
My example for doing the exact same below:
module Rack
class DirectoryIndex
def initialize(app)
#app = app
end
def call(env)
index_path = ::File.join($documentRoot, Rack::Request.new(env).path.split('/'), 'index.html')
if ::File.exists?(index_path)
return [200, {"Content-Type" => "text/html"}, [::File.read(index_path)]]
else
#app.call(env)
end
end
end
end
require 'rack_directory_index.rb'
$documentRoot = File.expand_path(File.join(File.dirname(__FILE__), '..', '..', 'build'))
Capybara.app = Rack::Builder.new do |builder|
puts "Creating static rack server serving #{$documentRoot}"
use Rack::DirectoryIndex
run Rack::Directory.new($documentRoot)
end
Capybara.configure do |config|
config.run_server = true
end
The solution is mostly a copy and paste from different answers but it works fine. You can find it as a gist here aswell, good luck
