Check if a class inherits from ActiveRecord::Base?

[Cyrille]

Hi guys,

I can't find a clean way to see if a class inherits from
ActiveRecord::Base...

At the moment, I do:

respond_to?(:id_before_type_cast)

But it's obviously a half-arsed solution...

Anybody can suggest something better?

Cheers

I've had problems in the past with is_a? but I can't remember why. The docs imply they are the same though.

Of course!

Thanks guys.
