Plugin: rails plugin install git@github.com:jeroeningen/acts_as_price.git
Gem: If you’re on Ruby 1.8, please use version 0.2.3 of the Gem. If you’re on Ruby 1.9 please use version 0.2.4 or higher.
Create a column in the table of your database which you want to acts as a price.
NOTE THAT THE COLUMN MUST BE OF THE TYPE INTEGER.
In your model add the following:
-
acts_as_price column_name, {:validates => true, :comma_seperated => true, :currency => currency}
column_name is the name of your database column e.g. price or price_per_liter.
validates is optional and add validation to the column
comma_seperated is optional and return the price comma seperated instead of dot seperated
currency is optional and adds a prefix for the currency to the price.
This plugin creates the following getters and setters:
-
‘price_in_cents’ and ‘<column_name>_in_cents’ #sets and returns the price in cents
-
‘price’ and ‘<column_name>’ #sets and returns the price
class Car < ActiveRecord::Base acts_as_price :price, :comma_seperated => true, :currency => "EUR" end
car = Car.new :price => 12999
car.price -> EUR. 12999,00
car.price_in_cents -> 1299900
class Fueltype < ActiveRecord::Base acts_as_price :price_per_liter, :validates => true end
fuel = Fueltype.new :price_per_liter => 1.12
fuel.price -> 1.12
fuel.price_in_cents -> 112
fuel.price_per_liter -> 1.12
fuel.price_per_liter_in_cents -> 1.12
Acts As Price comes with a helper method to automatically test the plugin using Rspec.
To use this method please add the following to your spec_helper.rb file:
-
config.include(ActsAsPriceHelper)
-
and if you using the gem, please also add: require ‘acts_as_price_helper’
Now you may add the following code to your spec-files for your models:
context "given an valid model" do it "should acts as price" do test_acts_as_price_methods <column_name>, <fixture or stub> end end
To test the plugin use the command ‘rspec spec/**’ inside the dir ‘~/vendor/plugins/acts_as_price’
The command ‘rake test’ is not running properly at the moment.
When creating a text_field, by default Rails gets the ‘raw’ value from the database, so you probably get the wrong value in your text_field. To prevent this please do the following:
f.textfield :price, :value => @object.price
This plugin comes with Rspec tests. However this plugin assumes that you have a database configuration, it actually don’t use the database for the Rspec tests.
