I have an ActiveRecord class called Foo that I’ve added some methods  
to in the foo.rb file.  
I have created an instance of Foo within another ActiveRecord Bar  
within the file bar.rb.

I keep getting this error:  
NoMethodError (undefined method `do\_some\_stuff’ for #Foo:0x3d61c14):

I very clearly have a method:

class Foo \< ActiveRecord::Base  
def do\_some\_stuff  
puts “I did some stuff”  
end  
end

Is there something I’m missing that is causing this?  
Do I have to call something to make this method available outside of  
the class?

Thanks, Bob

The foo you Foo’ed is not the foo you think you Foo’ed…

In other words, you’ll have to show the Bar code that created that  
pseudo-Foo before we can help.

nope. What does your actual code look like ?
