I'm using Unix system and trying to run Watir/Taza/RSpec test execution.
I just perform commands for creating taza structure, site, homepage and flow:
> taza create structure
> taza site google
> taza page home google
> taza flow search google
Then I run test using next command:
rake spec:isolation:google
but I get an error:
rake aborted! LoadError: cannot load such file -- taza/tasks

Who knows what to do?
And another moment I would like to dicuss - in file config/config.yml I have the following:
---
browser: firefox
driver: watir_webdriver
But on my Mac I don't have Firefox installed. How can I use this with, for example, Chrome and can it cause my problem?
1) Try this command:
rake spec:isolation
This worked for me.
2) Watir supports Chrome browser too. So just replace 'firefox' with 'chrome' and try to run your tests.

I trying to get ruby to read the source of a url thats being hosted on my own computer. I've tried using open-uri gem with:
source = open('http://127.0.0.1:8000/wikipedia_en_all_nopic_01_2012/A/Mick%20Jagger.html', &:read)
With normal external urls this works fine but it raises multiple errors when i try to access the url im hosting on my computer. Does anyone have any idea how to this? Heres the command line error report:

UPDATE: I'm using kiwix server to host the URL
Try using net/http instead.
require 'net/http'
source = Net::HTTP.get URI.parse('http://127.0.0.1:8000/wikipedia_en_all_nopic_01_2012/A/Mick%20Jagger.html')
Why do you want you use a URL if it's on the local machine? Why not just give the path?
That error sounds like there's something wrong with the actual file you're trying to parse, or the way it's being served by the way. From reading about Kiwix server it sounds like the latter...On the Kiwix site it says that it uses some type compression method called openzim which is most likely why open-uri can't find a way to parse it.
You could try nokogiri and see if it has a problem parsing it. But since it seems like you're trying to open/manipulate a zim file in ruby, I'd look for a zim library for ruby instead of trying to serve it.
Here:
https://github.com/chrisistuff/zim-ruby
I've never dealt with kiwix/zim, so I don't know if this one works but it was the only one the a google search for 'zim ruby' came back with.
I had the same problem with kiwix. I extracted all the URLs in a file called hrefs.txt (in my case it was the german project gutenberg) and used wget to download each of them:
f = File.open("hrefs.txt", "r")
f.each_line do |url|
#filename = url.split("/").last.gsub!(/[^A-Za-z]/, '')[0..-4]
system "wget #{url}"
end
f.close
I'm playing with Ruby / Sinatra at present and attempting to get HTTPS working.
I've taken a look at the rack:ssl gem here: https://github.com/josh/rack-ssl
It seems to be working when I run the application (as in redirecting to HTTPS), but nothing is displayed in the browser and the log comes up with the following error:
!! Invalid request
#!/usr/bin/env ruby
require 'rack/ssl'
require 'sinatra'
use Rack::SSL
get '/' do
'Hello World'
end
I'm not sure what to do from here.
Update:
Turned Thin Logging on in the sinatra app and got the following in the log:
!! Invalid request
Invalid HTTP format, parsing fails.

Any help would be greatly appreciated, thank you.
TLDR: Using require 'classname' in another model file (so I can deserialize a column) works locally but results in the No such file to load -- Classname error when deploying to Heroku.
I've made the admittedly poor design decision to serialize a model attribute which contains an array of another model's objects (UserCategoryQueue has a serialized queue of Card objects). In order to actually de-serialize these objects, I've followed the advice in YAML::load raises undefined class/module error to use require 'Card' in the files where I need to deserialize that column. That avoids the issue where YAML doesn't know what it's looking at when it gets to the Card object.
This works fine on the localhost server but has resulted in a lot of issues when deploying to Heroku, all of the form No such file to load -- Card". Initially, this occurred during the asset precompilation phase, then I precompiled the assets myself and the same error has moved to when I try to run $ heroku run rake db:migrate to get everything set up for the first time.
Sample Files:
# app/models/user_category_queue.rb
class UserCategoryQueue < ActiveRecord::Base
...
# Our queue of Cards
serialize :queue, Array
end
# app/models/quiz.rb
class Quiz < ActiveRecord::Base
...
require 'Card'
...
# grab a random card from the user's queues
# produces YAML error without the above require statement
def sample_card
self.user.user_category_queues.sample.queue.sample
end
end
This ultimately resulted in the following errors on pushing to Heroku (prior to any asset precompilation attempts on my part):
Running: rake assets:precompile
rake aborted!
No such file to load -- Card

As I said, even when precompiling assets, though the push went fine, the ensuing database migration had the same error pop up.
Heroku runs a case-sensitive filesystem, whereas your OS may not be case-sensitive. Try changing that require to this instead:
require 'card'
As a general rule of thumb, most files within Ruby are required using lowercase letters with underscores serving as a word separator, like this:
require 'card_shuffler'
I'm new to Capistrano and I've tried using Capistrano's DSL to run shell commands on the server ('run', 'execute', etc.), but it appears that it was deprecated. After searching and searching for a functional equivalent, I still am lost.

Tasks: TOP => deploy:do_something
In Capistrano v3, you must specify where you want to run the code by calling on with a list of hostnames, e.g.
task :execute_on_server do
on "root#example.com" do
execute "some_command"
end
end
If you have roles set up, you can use the roles method as a convenience:
role :mailserver, "root#mail.example.com"
task :check_mail do
on roles(:mailserver) do
execute "some_command"
end
end
There is some v3 documentation here: http://www.capistranorb.com/

If I delete the env.rb file from the support directory I get the follow error when running Cucumber:
Scenario: Using a vehicle factory to build a basic vehicle # Features\creating_a_vehicle_for_an_ai_bot.feature:6
Given I have vehicle factory # Features/creating_a_vehicle_for_an_ai_bot_steps.rb:1
uninitialized constant Object::VehicleFactory (NameError)
./Features/creating_a_vehicle_for_an_ai_bot_steps.rb:2:in `/^I have vehicle factory$/'
Features\creating_a_vehicle_for_an_ai_bot.feature:7:in `Given I have vehicle factory'
When I use it to build a basic vehicle # Features/creating_a_vehicle_for_an_ai_bot_steps.rb:5
Then I should have receive a basic vehicle # Features/creating_a_vehicle_for_an_ai_bot_steps.rb:9
Failing Scenarios:
cucumber Features\creating_a_vehicle_for_an_ai_bot.feature:6 # Scenario: Using a vehicle factory to build a basic vehicle
I've tried everything I can think of and my google-fu is failing me - I hope it's something non-trivial so I'm not embarrassed, but easy to fix, so that I can move on! :)
Thanks for the help!
Your class is called VehicleFactory but you're trying to call vehicle_factory.new in creating_a_vehicle_for_an_ai_bot_steps.rb.
Also, I believe Cucumber expects a particular directory structure:
RubyBots/
features/
step_definitions/
creating_a_vehicle_for_an_ai_bot_steps.rb
support/
env.rb
creating_a_vehicle_for_an_ai_bot.feature
You'll need to require your own files from env.rb appropriately. Ruby doesn't work out any paths for you. One way of auto-requiring files based on symbol name (the way Rails does it) is described in my blog post (it relies on ActiveSupport 2.3 but should be similar for the current version).
