A module for implementing the Service Object pattern that allows for custom "verbs".

Usage

Including CallMe in your class adds a call class method that instantiates an object of the class using the provided arguments and invokes its call method. For example:

johncarney

#!/usr/bin/env sh

# If you don't already have a pre-push hook in your working copy, simply copy 
# this into .git/hooks/pre-push in your working copy. If you already have a 
# pre-push hook, you'll have to integrate it with your existing hook.

function current_branch {
  git rev-parse --abbrev-ref HEAD
}

# Probes all model associations looking for ones with a scope that call
# `with_deleted`. Lists all such associations, along with the location in
# source that `with_deleted` is called.
#
# Usage:
#
#  $ rails runner script/associations-using-with-deleted.rb

The arel_extensions gem has a couple of bugs...

1. DateSub doesn't work:

(table[:column] - 10.hours).to_sql
# => NoMethodError: undefined method `to_sql' for nil:NilClass

2. For MySQL, DateAdd generates a double-minus when given a negative duration:

# Custom Psych parser that captures line number information from a YAML file.
#
# For a project I'm working on I need to be able to determine which line(s) in a YAML
# file a particular value comes from. There are a few bits of advice on the internet
# about this, the best of them that I've found involves monkey-patching, which is a
# fairly low bar for "best" in my opinion. I found it on Stack Overflow:

# Examples

#   MyModel.order(MyModel.arel_table[:name].asc.nulls_last)
#   MyModel.order(MyModel.arel_table[:name].desc.nulls_first)
module Arel
  module NullOrder
    def nulls_last
      Arel::Nodes::NullsLast.new self
