active_poro
Makes possible the use of has_many, has_one, belongs_to associations in POROs as you would expect
Installation
Add this line to your application's Gemfile:
gem 'active_poro'And then execute:
$ bundle
Or install it yourself as:
$ gem install active_poro
Usage
You may use ActivePoro::Model as a mixin to enable associations to be built between POROs Currently supported associations:
- has_many
- has_one
- belongs_to
Example:
require 'active_poro'
class Dog
include ActivePoro::Model
has_many :fleas
end
class Flea
include ActivePoro::Model
belongs_to :dog
endNow, with that in place you should be able to do
dog = Dog.new
flea_a = Flea.new
flea_b = Flea.new
# associate the fleas with the dog
dog.fleas = [flea_a, flea_b]
# now fleas have the dog associated back
flea_a.dog == dog
#=> true
# now fleas have the dog associated back
flea_b.dog == dog
#=> true
# if a new dog is created
another_dog = Dog.new
# and flea_b for example, jumps to it (i.e. is associated to this other dog)
flea_b.dog = another_dog
# then dog does not have flea_b now
dog.fleas
#=> [flea_a] # simplified output, not actual output on the console
# and another_dog gets flea_b
another_dog.fleas
#=> [flea_b] # simplified output, not actual output on the consoleThis also works with has_one and belongs_to as expected.
