I am writing a rake task which, at one point, uses a custom YAML file import method to seed the database.

At one point in the import code, I have:

ActiveRecord::Base.transaction do

Trying to run the rake task throws:

You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]

The stack trace points to the aforementioned line in the code.

Is there a way to instantiate ActiveRecord::Base during a rake task?

Thanks!
