Question

I have the following code:

class MyClass
    def method
        foo = MyClass.all
    end
end

which results in this error:

NameError (uninitialized constant MyClass::MyClass)

It works fine if I change it to self.all, but the existing code works fine when I deploy to Heroku. It’s only broken on my local system.

This is with a Rails 3.1.1 app and Ruby 1.9.2

Any ideas what’s up?

Answer 1

You shouldn’t have to do that. Assuming all is a class method and is not an instance method, do

class MyClass
    def method
        foo = self.class.all
    end
end

However, I think what’s causing your problem is that in production, classes are cached. In development, they get reloaded on every request.
