Associated With

In most of my rails applications I need to check if a certain object is associated with another object. I usually do this the long way, so I finally decided to create a plugin for a project I'm working on called Scrum&Cola

Example

Ok, first you'll need ActiveRecord classes, with associations.

class Post < ActiveRecord::Base
  belongs_to :author
end

class Author < ActiveRecord::Base
   has_many :posts
end

Next find a post, and an author.

post = Post.find(1)
author = Author.find(1)

Now lets see if they're associated.

post.associated_with? author

or I can do it the other way around

author.associated_with? post

This will return a true or false!

Tests

To run the tests, create a database associated_with_test and simply just into the plugin's directory and type rake

TODO

I still have to write tests for polymorphic relationships, but i've "tested" manually and it works fine.. expect them up soon.
