ACTS_AS-FU

Now you have no excuse for not test-driving your ActiveRecord
extending plugins.

Usage

In your spec_helper.rb (pretty sure this works with Test::Unit
too, I’ll leave you to figure it out though)

require ‘rubygems’ require ‘acts_as_fu’ require ‘spec’ Spec::Runner.configure do |config| config.include ActsAsFu end

Then in your specs:

describe "acts_as_gilmore_girls" do
  before(:each) do
    build_model :nerds do
      text :omg_omg_bio
      string :name
      string :favorite_scene
      
      validates_presence_of :favorite_scene
      
      def awesome?(show_name)
        show_name == "Gilmore Girls"
      end      
    end
  end

  it "should require favorite scene" do
    nerd = Nerd.new :favorite_scene => nil
    nerd.should_not be_valid
    nerd.errors.on(:favorite_scene).should_not be_nil
  end

  it "should think gilmore girls is awesome"
    nerd = Nerd.new
    nerd.awesome?("Gilmore Girls").should be_true
  end

  it "has other stuff" do
    # ETC!
  end
end

The build_model method allows you to build an ActiveRecord model on
the fly. It takes a block where you can specify columns and methods.

Single Table Inheritance

If you want to create a model that’s a subclass of another, you can
use the :superclass option:

build_model(:assets) do string :type string :name named_scope :pictures, :conditions => { :type => “Picture” } end build_model(:pictures, :superclass => Asset)

The Picture model will then be a subclass of the Asset model.

Custom database configuration

If the in-memory sqlite3 database doesn’t suit your needs, you can
specify an alternative configuration with the ActsAsFu.connect! method:

ActsAsFu.connect! \ :adapter => ‘mysql’, :database => ‘some-db’, :username => ‘some-user’, :password => ‘some-password’, :socket => ‘/path/to/mysql.sock’

Install

gem install nakajima-acts_as_fu —source=http://gems.github.com

TODO

• Maybe a couple more options… maybe.

NOTE

Despite the above example, watching Gilmore Girls doesn’t make you
a nerd. Probably.
