Set a kind name independently of the model name (App Engine datastore)

Question

As a Python programmer, I like my code to be reusable, I\'m trying to avoid kind name conflicts in my code (where two different models share the same kind name).

Just override the kind() method of your class:

class MyModel(db.Model):
  @classmethod
  def kind(cls):
    return 'prefix_%s' % super(MyModel, cls).kind()

You can define a custom baseclass that does this for you:

class ModuleModel(db.Model):
  @classmethod
  def kind(cls):
    return '%s_%s' % (cls.__module__, super(ModuleModel, cls).kind())

Any class that extends ModuleModel will have the name of the module it's defined in prefixed to the kind name.
