Description
Using the example project at https://docs.djangoproject.com/en/1.10/intro/tutorial02/.
The example project says to instantiate a model in this way:
q = Question(question_text="What's new?", pub_date=timezone.now())
However, if you do something silly like not assigning attributes:
q = Question("What's new?", timezone.now())
The model will still instantiate. What's super confusing is that if you forget to type in the attributes, then apply
q.save()
You get the bizarre error ValueError: invalid literal for int() with base 10: 'Question'
If a model object is created without an assigned attribute and the missing attribute has no default specified, then some type of warning should appear. I wasted about 3 hours today figuring out this dumb mistake; the error message isnt related to the initial error.
