I'm quite new to Ruby language (up to now I developed in Groovy + Grails) but since I was curious about it I wanted to try Sinatra on Ruby 1.9.2-p0.
I have a trivial website that is contained in /mywebpage
and has 2 files:
# blog.rb
get '/' do
'Hello World!'
end
get '/impossible' do
haml :index
end
and
#config.ru
path = File.expand_path "../", __FILE__
$LOAD_PATH << (File.expand_path ".") + "/views"
require 'haml'
require 'sinatra'
require "#{path}/blog"
run Sinatra::Application
then in the same folder I have a /views/
folder that contains index.haml
.
I try to run the server with rackup -p8080
but when I try to get /impossible
I receive the following error:
Errno::ENOENT at /impossible
No such file or directory - /home/jack/mywebpage/<internal:lib/rubygems/views/index.haml
By searching over internet it seems that this maybe caused by "." not being included in $LOAD_PATH
so I tried to add it or add directly views ./views
so that actually $LOAD_PATH.inspect
gives me correct path: ..., "/home/jack/mywebpage/views"]
But still it doesn't seem to work. Being quite new to the framework and the language I was wondering if I'm doing something wrong. any clues?
Running Sinatra with Ruby 1.9.2 the template directory is no longer implicitly 'views', you need to set it yourself.
set :views, File.dirname(__FILE__) + "/views"
Note that currently Ruby also has Kernel#__dir__()
method that is equivalent to File.dirname(__FILE__)
.
gem install sinatra --pre
I ran into a similar problem, and solved it like this. I didn't dig into the problem, but this is what I found and it works. It'll supposedly be fixed in the next version of Sinatra (which they should really get out the door, just to fix these few 1.9.2 bugs).
#!/usr/bin/env ruby
require 'rubygems'
require 'sinatra'
enable :run
get '/' do
"Hello, world!"
end
Edit: It seems there are multiple bugs with Sinatra on 1.9.2. This one will fix Sinatra apps not starting on 1.9.2. I don't use a views directory (I like to keep my apps single-file), so I didn't run into your particular problem. This fix most likely won't help you at all. I probably should have read your problem more closely..
