Find() - can it be overridden?

Hi, is it possible to override Active Record find() in a class that inherits Active Record?

eg.

def find    super    <blah blah> end

I've tried it and it doesn't seem to work!

It can be overridden, but it depends on your requirement. Do you just want to process a result_set returned from the super? Or do you want to pass additional options to the super? Or do you want to rewrite it completely?

It is a bit difficult say since the requirement is unclear.

Find is a class method. Your example below creates an instance method called find. To override the AR find class method do something like this:

def ClassName.find(*args) super(*args) end

Actually, super's default behaviour is to slurp up all the args that came into the method in the first place, so the argument is superfluous. See this post for an example of overriding find to set a default order for a model.
