Question

我面对着无法遍历我的表单集的问题。我已经在客户端模型（窗体）和电话模型（窗体集）之间创建了一个内联结构。我的目标是能够为每个客户存储多于一部电话。

问题在于，尽管我可以创建多个内联，但是在存储阶段，我的代码仅存储了最后一部电话，而不是预期的每部电话。

models.py

class Client(models.Model):
    name = models.CharField(max_length=50, verbose_name="Όνομα")
    surname = models.CharField(max_length=50, verbose_name="Επίθετο")
    amka_amesa = models.BigIntegerField( validators=[MaxValueValidator(99999999999)],null=True,blank=True, verbose_name="AΜΚΑ Άμεσα Ασφαλισμένου")
    amka_emesa = models.BigIntegerField( validators=[MaxValueValidator(99999999999)], unique=True, null=True, blank=True, verbose_name="ΑΜΚΑ Έμεσα Ασφαλισμένου")
    am_asfa = models.CharField( max_length=11, validators=[RegexValidator(r'^\d+$')], null=True, blank=True, verbose_name="Α.Μητρώου Ασφαλισμένου")
    address = models.CharField(max_length=100, null=True, blank=True, verbose_name="Διεύθυνση")
    ika_branch = models.ForeignKey(Client_IKA_Branch, null=True, blank=True, verbose_name=u'Υποκατάστημα Ασφαλισμένου')
    notes = models.CharField(max_length=100, null=True, blank=True, verbose_name="Σημειώσεις")
    #active field=1
    #inactive field=0
    INACTIVE, ACTIVE = range(0, 2)
    ACTIVITY_OPTIONS = (

        (ACTIVE, 'Ενεργός'),
        )
    activity = models.IntegerField(choices=ACTIVITY_OPTIONS, null=True,default=ACTIVE)

        if PhoneFormSet.is_valid() and form.is_valid():
            self.object = form.save() # saves Father and Children
            phones = PhoneFormSet.save(commit=False) 
            for instance in phones:

    def get_context_data(self, **kwargs):

            ctx['PhoneFormSet'] = ClientPhoneFormSet(self.request.POST)
        else:

我注意到 phones = PhoneFormSet.save（commit = False）行仅返回一个实例。为什么会这样？

任何帮助将不胜感激。

Answer 1

尝试更改

phones = PhoneFormSet.save(commit=False) for instance in phones: instance.save()

进入

phones = PhoneFormSet.save(commit=False) 
phones.instance=self.object
phones.save()

Answer 2

与模板中的前缀有关的修复。它必须是前缀：'phone_set'，而不是像我以前那样的前缀：'client_phone_set'。
