m = Model.find(1);
m.class_name would give you "Model"
If we have:
m = Model.find(:all);
How do we get the name of the model from m alone?

This won't work quite correctly if you've got inheritence. Given, say, `Media < ActiveRecord::Base`, `Record < Media`, and `ComicBook < Media`, `Media.find(:all)` will return some things that are `Record`s and some that are `ComicBook`s.

If you mean, how do you aggregate them all, since you are actually returning an array of Model objects, I recommend this:
Model.find(:all).collect(&:model_name)
This should give you an array of model names of the classes that you have returned from the database.

A:
If you are calling "Model", don't you already know the class?
If you call
Post.find(:all)
the returned records will be of class Post.

This is not always true. If you are dealing with an STI model, and you are querying the parent/base model, it can return subclasses of this that are known as different model names.
