13,141 PointsI want to understand primary keys (pk) and ids more. Help please?
I understand their functionality a bit, but sometimes get lost when they get so long, like in this anchor tag:
<a href="{% url 'courses:edit_quiz' course_pk=step.course.pk quiz_pk=step.pk %}"></a>
It's for this view:
@login_required
def quiz_edit(request, course_pk, quiz_pk):
quiz = get_object_or_404(models.Quiz, pk=quiz_pk, course_id=course_pk)
form = forms.QuizForm(instance=quiz)
return render(request, 'courses/quiz_form.html', {'form': form, 'course': quiz.course})

Full Stack JavaScript Techdegree Student 12,469 PointsWhat will you like to understand about (pk) here you're using a template to send values to the view function with the parameters specified and returning a html to the renderer and passing a form instance and accessing the course property on the quiz instance.

href="{% url 'courses:edit_quiz' course_pk=step.course.pk quiz_pk=step.pk %}"

13,141 PointsThank you.
href="{% url 'courses:edit_quiz' course_pk=step.course.pk quiz_pk=step.pk %}"So for instance in this href above >> The admin made it easier for me to digest. So just like how I would select the Course for a new quiz I'm hypothetically creating/editing in the admin, I select the course name related to that quiz. ▼▼
href="{% url 'courses:edit_quiz' course_pk=step.course.pk quiz_pk=step.pk %}"So I'm saying in this href: go to the courses:edit_quiz url (i.e. I'm in admin and I clicked on a question), and then once I'm there: I want you to access the quiz pertaining to that question). Is it sort of like that?
