How to solve the models error that Django throws?

Question

Django

Django throws this error on startup

RuntimeError: Model class docsie.translate.models.Estimate doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

I created a new class in models and came across this.
I think the error is common and not hard to solve.
