RSpec crashing with multiple Rails validation helpers

Question

I have two different validations for the :website attribute on my Customer model. One is the build in length helper, with the maximum set to 255, while the other is a custom validation. They both work individually, and the appropriate tests pass, but for some reason, when I run my tests with both validations, RSpec crashes to the point I have to complete exit out of Guard and restart it.

Here is my code, any way they are some how conflicting with each other? I have never experienced this before:

class Customer < Active Record::Base

  ...

  URL_REGEX = /(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:)*@)?(((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5]))|((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?)(:\d*)?)(\/((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(\#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)|\/|\?)*)?$/i

  validates :website, length: { maximum: 255 }
  validate :valid_urls

  private
    def valid_urls
      ["website", "blog", "contact"].each do |attribute|
        errors.add(attribute, "needs to be a valid url") if send(attribute).present? && URL_REGEX.match(send(attribute)).nil?
      end
    end
end

UPDATE: Thanks for the help, turned out the whole issue was just a bad regex. I had copied the regex from a stackoverflow thread, which had escaped some of the ampersands, producing a bad regex. I just now copied it from the jQuery validate source and it worked, sorry for the trouble.

Answer 1

Mackshkatz, can you try removing custom validation to use those provided by rails? As such:

class Customer < ActiveRecord::Base
  validates :website, format: { with: URL_REGEX }, allow_blank: true, length: { maximum: 255 }
  validates :blog,    format: { with: URL_REGEX }, allow_blank: true
  validates :contact, format: { with: URL_REGEX }, allow_blank: true
end

And see if it passes? It seems like the problem may be in complex regexp you are using.
