phone_type( for ) を選択して空のフォームを送信すると、フォームは規定formHomePhoneで選択された値なしでそれ自身を返しますphone_typeThis field is requiredビューからわかるように、フォームの最初の電話番号は必須ですが、他の電話番号は必須ではありません。値が存在する場合にのみ処理したい。空のフォームで [送信] をクリックすると、追加の電話番号フィールドからエラーがスローされますが、
UKPhoneNumberField>Phone number must include an area code.該当するフィールドに番号がある場合にのみ検証するにはどうすればよいですか?
このようなview.pyファイルがあります
def new_client_view(request):

次のようなforms.py：
class ClientDetailsForm(ModelForm):
class Meta:
model = ClientDetails
exclude = ('client', 'created', 'created_by')
class ClientAddressForm(ModelForm):
class Meta:
model = ClientAddress
exclude = ('client', 'created', 'created_by')
class ClientPhoneForm(ModelForm):
number = UKPhoneNumberField()
class Meta:
model = ClientPhone
exclude = ('client', 'created', 'created_by')
class ClientOtherPhoneForm(ModelForm):
number = UKPhoneNumberField(required=False)
class Meta:
model = ClientPhone
exclude = ('client', 'created', 'created_by')
そして、このようなmodels.py：
MARITAL_STATUS_CHOICES = (
...
)
NAME_TITLE_CHOICES = (
...
)
PHONE_CHOICES = (
('home', 'Home'),
('home2', 'Home 2'),
('mobi', 'Mobile'),
('mobi2', 'Mobile 2'),
('work', 'Work'),
('work2', 'Work 2'),
)
class Client(models.Model):
closed = models.DateTimeField(blank=True, null=True)
closed_by = models.ForeignKey(User, blank=True, null=True)
comment = models.TextField(blank=True, null=True)
def __unicode__(self):
return u'%s' % (self.id)
class ClientDetails(models.Model):
...
class ClientAddress(models.Model):
...
class ClientPhone(models.Model):
client = models.ForeignKey(Client, null=True)
created = models.DateTimeField(default=datetime.now)
created_by = models.ForeignKey(User, blank=True, null=True)
phone_type = models.CharField(max_length=5, choices=PHONE_CHOICES)
number = models.CharField(max_length=24)
ところで（私のnew_client_view機能はあまりDRYではありません。お勧めはありがたく受け取られます）
