You imported the wrong DecimalField class.  
What you imported is django.forms.DecimalField  
What you need to import is django.db.models.DecimalField  
VScode’s auto import can be your best friend and worst enemy at the same time. Lol

Happy coding;)

> Thank you some much.

VS Code _import django.forms.DecimalField_ by itself **which is wrong**. We need to _Import django.db.models.DecimalField_ which is the **right import** to resolve \> ‘get\_internal\_type’ issue.
