@Mahrez, it seems the same error so nothing changed. I test the code and the problem is that the form is not valid. Your answer is when the form is valid before to apply the save code. please, could you check again or anyone can help me, please.

def Insert_group(request):
    print(f" The begining Request method is : {request.method}")
