Question:

I finished Rails and I feel like I understand it pretty well, but I don't understand ActiveRecord or ORMs in general. How does calling save on my model get turned into data in the database?

Answer:

Well, calling the save method on a model, ActiveRecord#save, it will update a table row in this Rails app DB.

For example, when updating the duration of the Jaws movie model.
