Question

当我创建带有外键字段的新对象时，模板中是否有办法在创建表单上的模板中获取外键对象字段？每当我创建新便笺时，我都希望拥有：“将新便笺添加到{{申请人.full_name}}”

class Applicant(models.Model):
    first_name = models.CharField(max_length=128,blank=False, verbose_name="First Name")
    middle_name = models.CharField(max_length=128,blank=True, verbose_name="Middle Name")
    last_name = models.CharField(max_length=128,blank=False, verbose_name="Last Name")

    @property
    def full_name(self):
        "Returns the applicant's full name."
        return '%s %s %s' % (self.first_name, self.middle_name, self.last_name)

class Note(models.Model):
    applicant = models.ForeignKey(Applicant, related_name='notes', on_delete=models.CASCADE)
    description = models.TextField(blank=True)
)

（已更新）这是视图：

class NoteCreate(CreateView):
    model = Note
    form_class = forms.NoteForm
    template_name = 'careers/add_note.html'

    def form_valid(self, form):
        applicant_pk = self.kwargs['pk']
        applicant = Applicant.objects.get(pk=applicant_pk)
        self.object = form.save(commit=False)
        self.object.applicant = applicant
        self.object.save()
        return super(NoteCreate, self).form_valid(form)
