Question

无法使用inlineformset工厂将数据保存到模型外键（具有OneToOne关系）

创建inlineformset，然后创建视图以从表单集中捕获数据（它具有OneToOne关系）

models.py

class Bed(models.Model):
 bed_no = models.CharField(primary_key=True,max_length=10, blank=True)
room_no = models.ForeignKey('Room', on_delete=models.SET_NULL, null=True)
----- and so on


class Guest(models.Model):
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=20)
allotted_bed =  models.OneToOneField(Bed,on_delete=models.SET_NULL, null = True)
-------- and so on

forms.py

GuestFormSet = inlineformset_factory(Bed, Guest,
        fields='__all__',can_delete=False)

views.py

def guestinline(request, pk):
    allotted_bed = Bed.objects.get(bed_no=pk)
    if request.method == 'POST':
        formset = GuestFormSet(request.POST,request.FILES, instance = allotted_bed)
        if formset.is_valid():
            formset.save()
            return HttpResponse('Sucess')
        else:
            print(formset.errors)
    else:
        formset=GuestFormSet(instance=allotted_bed)
        return render(request,'add_guest.html',{'formset':formset})

add_guest.html

<body>
    <form>
        {{formset.as_p}}
        <button>Save</button>
    </form>
</body>

预期输出：

      Success

实际结果：
