Class Name in Model

Do the Class Name in the Model should be the Name of App? Is it mandatory. I am getting the error as

"Product doesn't declare an explicit app_label and either isn't in an applic ation in INSTALLED_APPS or else was imported before its application was loaded. This will no longer be supported in Django 1.9. class Product(models.Model):"

As stated in this SO answer:

As stated in the warning, this happens either :

  • When you're using a model which is not in an INSTALLED_APPS;
  • Or when you're using a model before its application is loaded.

Make sure the file containing Product is in a directory listed in settings.INSTALLED_APPS And that the directory includes a __init.py__ file and the file referencing your models.Product is listed later in the list, if in a different module.
