Base class model not found, even with require

I want to create a base class for a few of my models, as follows:

class SingletonRecord < ActiveRecord::Base
def self.get
instance = self.find_all[0]
instance ||= Current.new
return instance
end

    def save
            self.delete_all
            super
    end

end

Then I create a subclass model like so:

require ‘singletonrecord’

class Current < SingletonRecord
end

This works great in the console, i.e. Current.get does what I’d expect.
But it doesn’t work through the web interface - it tells me
“SingletonRecord uninitialized constant”.

Why?

Hi Adam,

You shouldn’t have to put the ‘require’ at the top of the file. Rails
can find your models as long as they’re named correctly according to the
convention.

What is the filename you have SingletonRecord saved as? It should be
singleton_record.rb.

Adam,

I didn’t notice you were including it as ‘singletonrecord’, so I’m
assuming you have your file named singletonrecord.rb. Rename it to
singleton_record.rb and remove the require ‘singletonrecord’ line. Rails
will automagically find singleton_record.rb when you extend from
SingletonRecord in your Current class.
