How to use Icescrum with Dashing (widget)? - ruby

Question

I am trying to create a widget on Dashing that will extract data from Icescrum and update a specific widget.
The thing is I found info on how to program jira, so i've been trying to mess around with it to make it work with icescrum, but with no luck.
I tried this one:
require "uri"
require "net/http"
require "json"
SCHEDULER.every '2s', :first_in => 0 do |job|
uri = URI.parse("http://website.ca:8080/icescrum")
http = Net::HTTP.new(uri.host, uri.port)
req = Net::HTTP::Get.new("uri.request_uri")
req.basic_auth username, password
response = http.request(req)
issuesinProgress = JSON.parse(response.body)["total"]
send_event('synergy', value: issuesinProgress)
end
but I got this error:
scheduler caught exception:
undefined local variable or method `username' for main:Object
/home/administrator/dashboard/jobs/sample.rb:27:in `block in <top (required)>'
/var/lib/gems/1.9.1/gems/rufus-scheduler-2.0.24/lib/rufus/sc/jobs.rb:230:in `call'

/var/lib/gems/1.9.1/gems/rufus-scheduler-2.0.24/lib/rufus/sc/scheduler.rb:430:in `block in trigger_job'

Answer 1

Your code has a line:
req.basic_auth username, password
It's expecting two variables, "username" and "password", but neither look to be defined in your code, here. If they aren't defined you'll get an error that looks an awful lot like what you're getting.

Answer 2

So finally I just used a cURL function to get the information. I'll leave it here if anyone else needs it. It also sends the results to an xml file (if you don't want that then just remove the last part)
.rb file:
%x{curl -v -H "Content-Type: application/xml" -X POST --data "#filename.xml" -u username:password http://website.ca:8080/icescrum/ --output result.xml}
Remember to change these dummy names with your links:
filename.xml
username
password
website.ca:8080/icescrum/
result.xml
