    [update, 9:27 a.m., 8/1/2007: welcome, reddit readers. annoyed at me for calling this post “10 things”? Well, then you’ll really hate me after reading this post!]

     

    1. method_missing is a Ruby kernel method and everyone should know about it.

     

    2. Rails implements some of its funkiest magic with method_missing. When you ask your model to find_by_freaky_column_name, and it does so, that’s because ActiveRecord::Base overrides the kernel’s method_missing method.

     

    3. method_missing is the method of last resort. When you send a message to a Ruby object, Ruby looks for a method to invoke with the same name as the message you sent. (There are a bunch of different ways to send the message, but the most common one is just obj.method_name. But you can make the fact that you are sending a message explicit by using obj.send(:method_name)). First it looks in the current self object’s own instance methods. Then it looks in the list of instance methods that all objects of that class share, and then in each of the included modules of that class, in reverse order of inclusion. Then it looks in that class’s superclass, and then in the superclass’s included modules, all the way up until it reaches the class Objec
