Rails ActiveRecord Relationships Flowchart

One of the remarkable things about Rails is how easy it is to create and manage relationships between objects. ActiveRecord provides this powerful and flexible object-relational mapping (ORM) capability.

Even though there are only a handful of methods involved, it can sometimes be a little confusing to newcomers; and even when you’ve got the big picture down, you might need help remembering the small details, like where to put the foreign key.

To that end, I created a simple flowchart that guides you through the process of setting up your ActiveRecord associations. It’s pinned to the wall next to my desk; hopefully you’ll find it a handy reference as well.

    Looks good; I’d definitely pass this off to anybody getting their feet we with Rails. It took me a while to burn this information into my brain.
