Inverse relation using "through"

At several points in our code, we might do something similar to the following:

$parentClass = ParentClasses::model()->findOneByPk($parentClassId);
...
$sessions = $parentClass->sessions;
foreach ($sessions as $session) {
    // Do something with the parent class of the session, perhaps
    // rendering it in a subview
    $parentClass = $session->parentClass;
    echo $parentClass->title;

A description of the "userVote" type of problem, with proposed solutions including their drawbacks and advantages

The userVote Problem

We are struggling to find a way to efficiently and cleanly implement the following common use case in our code base:

  • There is an object that can be voted on
    • Project
    • Discussion
    • Comment
  • We have an array of these objects
  • We would like to know if a user has voted on each of these objects
  • We need to associate each of these Vote objects with its respective Project, Discussion or Comment, if it exists
  • Throughout our view hierarchy, we need easy access to these related Votes in the same locations that we need access to the associated Vote object, such that the pattern for accessing them is clear, simple to repeatedly implement, and preferable to any sort of "hacky" workaround solution. (Such as making $userVote a public property of the voted object, or defining a "shortcut" relation-that-is-not-a-relation to access the vote.)

How Homakov hacked GitHub and how to protect your application

##How Homakov hacked GitHub and the line of code that could have prevented it

Please note: THIS ARTICLE IS NOT WRITTEN BY THE GITHUB TEAM or in any way associated with them. It's simply hosted as a Gist because the markdown formatting is excellent and far clearer than anything I could manage on my personal Tumblr at peternixey.com.
