Error: NoReverseMatch when adding quiz to module content

Courses
1

I’m working on a quiz app for my e-learning project. When I try to add a new quiz to the module content, I get this error:

Reverse for 'new-quiz' with arguments '('', '')' not found. 1 pattern(s) tried: ['courses/(?P<courses_id>[^/]+)/modules/(?P<modules_id>[^/]+)/quiz/newquiz\Z']

Here’s my setup:

  • I have models for Answer, Question, Quizzes, Attempter, Attempt, and Completion
  • Views include NewQuiz, NewQuestion, QuizDetail, TakeQuiz, SubmitAttempt, and AttemptDetail
  • URL patterns are set up for these views
  • I’m using a template to add quizzes and content

I’ve double-checked my URL patterns and view functions, but can’t figure out why it’s not finding the correct URL. Any ideas what might be causing this error or how to fix it?

This error typically occurs when Django can’t resolve the URL for ‘new-quiz’ due to missing or incorrect arguments. Based on your URL pattern, it seems the ‘courses_id’ and ‘modules_id’ are required but not being passed correctly.

Check your template where you’re creating the link to add a new quiz. Ensure you’re passing both ‘courses_id’ and ‘modules_id’ in the URL. It might look something like this:

{% url 'new-quiz' courses_id=course.id modules_id=module.id %}

Also, verify that these IDs are available in the context when rendering the template. If you’re using class-based views, make sure you’re overriding get_context_data() to include necessary context variables.

If the issue persists, review your view function/class to confirm it’s receiving and handling these parameters correctly. Sometimes, a mismatch between URL configuration and view parameters can cause this error.

hey exploringforest, sounds like a gnarly bug. have u logged ur courses_id and module_id? sometimes they come through empty. maybe that is why reverse can’t find the url. try double-checking their values.

Hey there ExploringForest! :deciduous_tree:

Oof, that NoReverseMatch error can be a real pain, huh? I’ve definitely been there before. Have you tried printing out the values of courses_id and modules_id right before you try to add the quiz? Sometimes those sneaky variables can be empty without us realizing it.

Also, just a thought - are you sure you’re passing the correct arguments when you’re trying to create the new quiz? Maybe double-check the function call where you’re adding the quiz to make sure it matches up with what your URL pattern is expecting.

Oh, and one more thing - have you considered using the {% url %} template tag in your template? It can be super helpful for making sure your URLs are generated correctly. Something like:

{% url ‘new-quiz’ courses_id=course.id modules_id=module.id %}

Just make sure ‘course’ and ‘module’ are actually available in your template context.

Let me know if any of that helps or if you need more ideas. Debugging can be frustrating, but we’ll figure it out together! :blush:
