I need help linking a new Note instance to its corresponding Task instance using a Django CreateView. I want the primary key of the Task to be passed so that each Note is associated with the right Task. I've set up two models: Task and Note. The Note model has a foreign key to Task, as shown below:

PYTHONCopied
class Note(models.Model):
    task = models.ForeignKey(
        Task, on_delete=models.CASCADE, related_name="notes", null=False, blank=False
    )  # Required, links to tasks.Task
    text = models.TextField(
       null=False, blank=False,
    )  # Required

The TaskDetailView renders a template (task_detail.html) which includes a link to add a new note:

<a href="{% url 'tasks:note_new' task.id %}" class="btn btn-primary">Add Note</a>

The urls.py maps the request like this:

path("note/int:task_id/", NoteCreateView.as_view(), name="note_new"),

The NoteCreateView is defined in views.py as follows:

PYTHONCopied
class NoteCreateView(CreateView):
    model = Note
    form_class = NoteForm
    template_name = "tasks/note_detail.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context["page_title"] = "New Note"
        return context

    def form_valid(self, form):
        form.instance.author = self.request.user
        form.instance.task_id = self.kwargs.get("task_id")
        print("\nin form_valid: ", self.kwargs.get("task_id"))
        return super().form_valid(form)

    def get_success_url(self, **kwargs):
        return reverse_lazy('tasks:edit', kwargs={'pk': self.kwargs.get("task_id")})

The associated ModelForm in forms.py is:

PYTHONCopied
class NoteForm(ModelForm):
    
    class Meta:
        model = Note
        fields = ["text"]
        widgets = {
            "text": forms.TextInput(attrs={
                    "class": "input input-primary"
                 }
                )
            }

The note_detail.html template is defined as:

HTMLCopied
<form action="{% url 'tasks:note_new' task_id=task.id %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Save" class="btn btn-accent" />
</form>

However, I encounter the following error:

NoReverseMatch at /tasks/note/85/

Reverse for ‘note_new’ with keyword arguments ‘{‘task_id’: ‘’}’ not found. 1 pattern(s) tried: [‘tasks/note/(?P<task_id>[0-9]+)/\Z’]

Even though 85 is the correct pk for the Task, it appears that the primary key is not being passed when the CreateView is rendered, causing a failure in reversing the URL in note_detail.html. I suspect that the Task primary key is not properly propagated from the TaskDetailView that provides the link to the NoteCreateView. How can I ensure that the Task pk is correctly passed and utilized in the CreateView?
