How can I throw pk to forms.py django

moneylog get relation with moneybook, and when i create moneylog, I wanna moneybook of moneylog choose default=moneybook.pk

and these are my codes.

moneylog/model.py

moneybook = models.ForeignKey(
    moneybook_models.Moneybook, on_delete=models.CASCADE)

moneylogs/urls.py

app_name = "moneylogs"

urlpatterns = [
    path("create/<int:pk>/", views.moneylog_create.as_view(), name="create"),

moneybooks/detail.html

<a style="display:scroll;position:fixed;bottom:50px;right:30px;" href="{% url 'moneylogs:create' pk %}">
        <div class="rounded-full h-16 w-16 flex items-center justify-center bg-red-400 text-bold font-bold text-white">+</div>
    </a>

so if i click the + button, then

moneylogs/views.py

class moneylog_create(FormView):

    form_class = forms.CreateMoneylogForm
    template_name = "moneylogs/create.html"

    def form_valid(self, form):
        moneylog = form.save()
        moneylog.save()
        return redirect(reverse("cores:home"))

moneylog/forms.py

class CreateMoneylogForm(forms.ModelForm):
    class Meta:
        model = models.Moneylog
        form.fields['moneybook'].initial = moneybook_models.Moneybook.objects.get(
            pk=pk)
        fields = (
            "pay_day",
            "payer",
            "dutch_payer",
            "price",
            "category",
            "memo",
        )
        widgets = {
            "dutch_payer": forms.CheckboxSelectMultiple
        }

    def save(self, *args, **kwargs):
        moneylog = super().save(commit=False)
        return moneylog

but it doesn't work. as you see.. how can i transfer moneybook.pk to moneylogs forms.py? or how can achieve moneybook belongs to moneybook default?

You don't need to pass moneybook obect to the form. Instead you can set it on view level:

class moneylog_create(FormView):

    form_class = forms.CreateMoneylogForm
    template_name = "moneylogs/create.html"

    def form_valid(self, form):
        moneybook = Moneybook.objects.get(pk=self.kwargs["pk"]
        form.instance.moneybook = moneybook
        return super().form_valid(form)
