Agowan / context.rb

A simple way of handling custom sql queries without involving ActiveRecord. (Using postgresql)

 # encoding: utf-8
 class Context
   class Context::Result
     def initialize(*args, &block)
       args.extract_options!.each do |attr, value|
         send("#{attr}=", numeric?(value)) if respond_to?("#{attr}=")
       end

A way of encapsulate custom sql within objects and of course it's possible to make really clean with more inheritance.

 # encoding: utf-8
 class Context
   def sanitize_sql(array)
     self.class.sanitize_sql(array)
   end
   def select_all(sql)
     self.class.select_all(sql)

Agowan / album_form.rb

Last active April 5, 2016 20:50

A simple way to use has_many between form objects using Virtus.The problem I had was to get validations working with fields_for in the view, but still have the flexibility and full control using virtus instead of active record models.And I added a way of checking for sanitised args in rails 4.

	# encoding: utf-8

	class AlbumForm < BaseForm

	has_many :songs, class_name: 'SongForm'

	validates :songs, form_collection: true

	end

Without using squeel, default scope with sorting inherited to STI sub class

	# encoding: utf-8

	gem 'sqlite3', '1.3.6'
	gem 'activerecord', '3.2.8'

	require 'active_record'

	require 'logger'

	puts "Active Record #{ActiveRecord::VERSION::STRING}"

Agowan / bug-report.rb

Created September 11, 2012 16:46

Squeel bug report (duplicated "order by" when using default_scope inherited to a STI sub class)

	# encoding: utf-8

	gem 'sqlite3', '1.3.6'
	gem 'activerecord', '3.2.8'
	gem 'squeel', '1.0.11'

	require 'active_record'

	require 'squeel'
	require 'squeel/version'
