When developing an application where you have split out shared functionality to multiple dependent gem repositories can get cumbersome when you

• need to edit the Gemfile in order to swap local :path sources with :git or just plain Rubygems sources,
• then forget to bundle update,
• wonder why your git repository is dirty and it's just the modified Gemfile and Gemfile.lock,
• accidentally commit the Gemfile.lock with local :path sources bundled etc. etc.

So what about this strategy:

A. Create a file .Gemfile.local containing:

class UrlValidator < ActiveModel::EachValidator

  def validate_each(record, attribute, value)
    valid = begin
      URI.parse(value).kind_of?(URI::HTTP)
    rescue URI::InvalidURIError
      false
    end
    unless valid
      record.errors[attribute] << (options[:message] || "is an invalid URL")

  desc 'pull down the lastest backup from production'
