I need to test for URL submissions that contain duplicate protocols
-- which usually means a user pasted a link into a text field too
many times.
In PHP, I'd use the substr_match function for this... but I can't
find a good Ruby replacement.
Here's the test code I've written so far:
# fake url
url = 'http:/site.com/link.ics http://site.com/link.ics http://
site.com/link.ics'
#count the number of times '://' appears
count = 0
url.scan /:\/\// do |match|
count += 1
end
#is this a bad url?
if count > 2
puts 'this is a bad url'
end
This works, but doesn't seem like the Ruby way. Is there a better path?
....
Ultimately, I'm aiming for some crazy one-line Ruby magic like this...
if url.some.ruby.method./(:\/\/)/ > 2
errors.add(:url, "is too long. Bad cut and paste?")
end
Best,
Patrick
