Code style

• Use UTF-8. It’s 21 century, 8bit encodings dead now.
• Use 2 space indent, not tabs
• Use Unix-style line endings
• Keep lines not longer than 80 chars

# Patch for ransack (https://github.com/ernie/ransack) to use scopes
# Helps migrating from Searchlogic or MetaSearch
# Place this file into config/initializer/ransack.rb of your Rails 3.2 project
#
# Usage:
#   class Debt < ActiveRecord::Base
#     scope :overdue, lambda { where(["status = 'open' AND due_date < ?", Date.today]) }
#   end
#
#   Ransack out of the box ignores scopes. Example:

harssh

#paste this code in your ransack.rb initializer
#if you want to use scopes on search or sort please use Class.ransack_with_scopes instead of Class.search
Ransack::Adapters::ActiveRecord::Base.class_eval do
	def ransack(params = {}, options = {}, scope_used_on_sort = false)
		Ransack::Search.new(self, params, options, scope_used_on_sort)
	end
	def ransack_with_scopes(params = {}, options = {})
		scope_used_on_sort = false
		ransack_scope = self
		ransack_params = {}

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

    # Because we have some old legacy users in the database, we need to override Devises method for checking if a password is valid.
    # We first ask Devise if the password is valid, and if it throws an InvalidHash exception, we know that we're dealing with a
    # legacy user, so we check the password against the SHA1 algorithm that was used to hash the password in the old database.
