The following code gives me an error:
class_vars = ['fruit','cow','coffee'].each do |class_var|
"#{class_var}".classify.send(:find, 1 + rand(10))
end
The error message stack:

What I am trying to do here is, convert a string to an ActiveRecord
class and then send a AR method like find to it. But it doesn't work.
I have all the classes defined.

If you just poke around in the console you'll see that
'fruit'.classify #=> 'Fruit'
That's a string, not a Class (i.e. classify is just a string
transformation that camelcases or whatever is has to do).
You can use constantize to actually get the class you're talking about.
