I have a controller which wish to include a file in another folder, how do I do that? I am using Ruby 1.9.2 and Rails 3.2.6. Thanks
Controller file is in
/project/app/controllers/examples_controller.rb
and the required file is in
/project/example_folder/example.rb
require File.join(Rails.root, "example_folder", "example")
assuming /projects/ is your rails application root folder
You can auto load custom directories with classes and modules you want to be.
So you can Edit config/application.rb
# Custom directories with classes and modules you want to be autoloadable.
config.autoload_paths += %W(#{config.root}/example_folder)
It would be something like this:
require "#{Rails.root}/example_folder/example.rb"
just before the declaration of your controller.
according to here
more info here Why does Ruby 1.9.2 remove "." from LOAD_PATH, and what's the alternative?
requie_relative '../../example_folder/example.rb'

I have a Ruby app that runs on a server with no web interface. It is run using the command line(ruby path/to/file.rb).
I have classes in different files that I want to be accessible. The files are located in the "app/classes" directory.
I put this in the application.rb file:
config.autoload_paths += Dir["#{config.root}/classes"]
and I get an uninitialized constant error.
I can put in "require_relitive 'somefile'" but I would rather not have to do this for every class that is used. How do I create an autoload path and where should it be located at?
Use require_all
See https://github.com/jarmo/require_all
It basically allows you to write this:
require 'require_all'
require_all 'app/classes'
And all ruby files in app/classes will be loaded.
I am trying to follow this tutorial:
http://net.tutsplus.com/tutorials/ruby/singing-with-sinatra/
Got stuck in "We’ll also make use of a “view file”, which allows us to split the markup for a view into a separate file. "
I have my basics.rb file running fine.
And My files are stored as follows:
Desktop/RubyForm/basics.rb
Desktop/RubyForm/view/form.erb
However, now when i go to http://localhost:9393/form , I am greeted with:
Errno::EIO at /form
Input/output error - <STDERR> file: lint.rb location: write line: 398
sinatra.error
Errno::ENOENT: No such file or directory -
/Users/HelenasMac/Desktop/views/form.erb
UPDATE! : Got the form to work right after running ruby basics.rb and going to http://localhost:4567/form .
However, after I run "shotgun basics.rb" , I have to go to
http://localhost:9393/form, and that's when the form doesn't show up.
What am I doing wrong? Disclaimer: mega beginner to ruby and using the terminal.
Thanks in advance!
If you cannot get shotgun to work then the new recommended way to reload Sinatra seems to be rerun.
To use it:
> gem install rerun
> cd /Users/HelenasMac/Desktop/RubyForm
> rerun ruby basics.rb
Explicity Set a Views Directory
Unless you're using inline template for your views with enable :inline_templates, you may need to explicitly define a template directory if the default values aren't working for you. The docs describe how to set your views directory as follows:
:views - view template directory
A string specifying the directory where view templates are located. By default, this is assumed to be a directory named “views” within the application’s root directory (see the :root setting). The best way to specify an alternative directory name within the root of the application is to use a deferred value that references the :root setting:
set :views, Proc.new { File.join(root, "templates") }
You may also need to explicitly set :root, and make sure that both :root and :views make sense from your current working directory.
My test folder is inside lib/foo/test instead of /test. How can I tell Autotest to look at lib/foo/test for the tests to run? I tried to add some hooks with mappings in the .autotest file but got no success. Thanks in advance.
I'm sorry for not providing a direct answer, but I've stopped using Autotest myself and switched to Guard. Guard is a plain Ruby process that sits outside test::unit or rspec and as such it's much more configurable.
https://github.com/guard/guard
What you want is easy to accomplish in Guard, just write a Guardfile in the project root and mention the directory to watch:
watch("lib/foo/test") { |m| "test/lib/foo/test/#{m[1]}_test.rb" }
obviously tailoring it further to your need.
I think I'm missing something here. I have a directory like this:
myapp
|-lib
|-package1
|-dostuff.rb
|-package2
|-dostuff.rb
From an irb console I'm trying to test the library before I add it to my real project (a Rails app). However, typing this:
require 'lib/package1/dostuff'
returns an error saying it can't find the file to load. I added the lib directory to the load path but I'm not able to load the file.
What am I forgetting? The two filenames don't have to be the same but that's how they are to begin with (they are auto-generated from some web services I need to call using soap4r; each package represents a different web service API group)
If the directory "lib" is in the load path, the argument to require must be relative to lib. So require 'package1/dostuff' without the lib, otherwise it will look for lib/lib/package1/dostuff.rb.
In Ruby 1.9 there's the new require_relative method, which would let you do require_relative "../package2/dostuff" from within package1/dostuff.rb.
I'm creating a gem which has
several scripts in the bin directory
the utility classes in the lib directory
and several tests in the test directory
supertool
bin
toolA
toolB
lib
supertool
supertool.rb
helper.rb
test
tc_main.rb
tc_etc.rb
Now, to run the tests before I even install the gem, I have the following snippet at the top of my tests:
base = File.basename(Dir.pwd)
if base == 'test' || base =~ /supertool/
Dir.chdir('..') if base == 'test'
$LOAD_PATH.unshift(Dir.pwd + '/lib')
Dir.chdir('test') if base =~ /supertool/
end
This seems tedious though, especially if I have to put these in the scripts in the bin directory too. Is there a better way of setting up the environment so we can test gems before they are installed? I'm sure it's something simple that I just can't find. A simple link to the right place would help a lot :)
I'm not sure what you're trying to achieve with that script. It doesn't seem to have anything to do with gems...
Is it so that you can run ruby tc_main.rb from within the test directory (or ruby test/tc_main.rb from the base dir), and have it set the load path appropriately? If so, here's a much nicer way:
In your test directory, create a test_helper.rb file. In that file, put this
$LOAD_PATH << File.expand_path( File.dirname(__FILE__) + '/../lib' )
And in all your test files, set the first line to
require 'test_helper'
If you have subdirectories inside your test dir, then files in those subdirs can just do
require '../test_helper'
Take a look at hoe gem, it is a helper for other gems.
