Registering label from code in model?

Question

Django

Let's say I have a django project

I'm creating a model

class CodeContext(models.Model):
     label = models.CharField('метка в коде', ...)
     ...

create a decorator

def register_code_label(label, ...):
    CodeContext.objects.get_or_create(label=label)
    ...

which I hang on some functions or methods

@register_code_label('method1', ... )
def method1():
     ...

As planned, at the start of the project, records should be created in the database with label codes, but the application crashes with AppRegistryNotReady.
What is the best way to register such labels?
