Ohm ARFreaks

Ohm::Model extensions for AR freaks

Install

$ sudo gem install ohm-arfreaks

Models

AR freaks will be puzzled that Ohm::Model lacks well known methods like first, count, etc. This library provides some of them to Ohm::Model.

Example

require 'ohm-arfreaks'

class Video < Ohm::Model
  attribute :url
  set       :tags
end

Video.first
=> #<Video id: 470, url: "a", tags: []>

Video.create!(:url=>...)
Video.new.save!

Available Methods

def self.primary_key        # AR
def self.columns            # AR
def self.column_names       # AR
def self.content_columns    # AR
def self.columns_hash       # AR
def self.create!(attributes) # AR
def save!                   # AR
def self.first(*args)       # AR
def self.last(*args)        # AR
def self.count(*args)       # AR
def self.delete_all(cond = nil) # AR
def new_record?             # AR
def attributes              # AR

NOTE

Ohm::Model#attributes returns an names of attributed fields in vanilla ohm gem. Of course, it's not familier to our ar-freaks, so it's overwritten by this gem.

 class Video < Ohm::Model
   attribute :url
   set       :tags
 end

 Video.first.attributes
 => [:url]                   # in vanilla ohm
 => {:url=>"a", :tags=>[]}   # in ohm-arfreaks

Test

% redis-server spec/redis.conf   # running on port:6380 in default
% spec -c spec
