Your instance of the form you are working with is named `form` (the first line of this excerpt).

_That_ is what you want to save at the last line of this portion:  
`quiz = form.save(commit=False)`

See [Creating forms from models | Django documentation | Django](https://docs.djangoproject.com/en/4.0/topics/forms/modelforms/#the-save-method) for more details.

Absolutely! This is a “conversational” location, not an “ask one question, get one answer” type of site.

Ok, this was a more targeted question.

You posted this line:

> `return redirect('new-question', course_id=course_id, module_id=module_id, quiz_id=quiz_id)`

which is the line throwing the error.

What part of _this_ line do you think the error is referring to?

And, the second question is:

> [@HAB-DOTCOM](#):
>
> NameError: name ‘quiz\_id’ is not defined

What do you think the cause of this error would be?

</div>

i think quiz\_id is not defined in NewQuiz function but i was think that when i save the quiz in quiz.save() method the quiz\_id was also crated for that quiz…but my thought is not worked so when i think onther way of getting the quiz\_id of the crating quiz ```  
quiz.id=quiz\_id

```auto

```

</div>

Correct. You have no variable defined named quiz\_id. What you are trying to reference _here_ is the `id` attribute of the `quiz` object, which is `quiz.id`, not `quiz_id`. Yes, there are a small number of places where you can use either one almost interchangably (within the ORM), but this is not one of them.

</div>

i mean when i tray like this

```auto
quiz_id = quiz.id

```

another probleme is come

# NoReverseMatch at /quiz/1/modules/1/quiz/newquiz

Reverse for ‘new-question’ not found. ‘new-question’ is not a valid view function or pattern name.

Ok, so we’ve solved the quiz.id issue, now it’s a different problem.

Yes, you are correct, this is the right error.

What do you think might cause this error?
