这一切的新手!我正在努力在前端显示电话字段显示为 (xxx)xxx-xxxx。下面是我的代码。我的问题是 1. 所有字段都是强制性的,由于某种原因,手机的行为不符合预期。即使它留空也不会抱怨 2.我如何测试这个小部件的功能
class USPhoneNumberWidget(forms.MultiWidget):
def __init__(self,attrs=None):
widgets = (forms.TextInput(attrs={'size':'3','maxlength':'3'}),forms.TextInput(attrs={'size':'3','maxlength':'3'}),forms.TextInput(attrs={'size':'3','maxlength':'4'}))
super(USPhoneNumberWidget,self).__init__(widgets,attrs=attrs)
def decompress(self, value):
if value:
val = value.split('-')
return [val[0],val[1],val[2]]
return [None,None,None]
def compress(self, data_list):
if data_list[0] and data_list[1] and data_list[2]:
ph1 = self.check_value(data_list[0])
ph2 = self.check_value(data_list[1])
ph3 = self.check_value(data_list[2])
return '%s''%s''%s' %(ph1,ph2,ph3)
else:
return None
def check_value(self,val):
try:
if val.isdigit():
return val
except:
raise forms.ValidationError('This Field has to be a number!')
def clean(self, value):
try:
value = re.sub('(\(|\)|\s+)','',smart_unicode(value))
m = phone_digits_re.search(value)
if m:
return u'%s%s%s' % (m.group(1),m.group(2),m.group(3))
except:
raise ValidationError('Phone Number is required.')
def value_from_datadict(self,data,files,name):
val_list = [widget.value_from_datadict(data,files,name+'_%s' %i) for i,widget in enumerate(self.widgets)]
try:
return val_list
except ValueError:
return ''
def format_output(self,rendered_widgets):
return '('+rendered_widgets[0]+')'+rendered_widgets[1]+'-'+rendered_widgets[2]
class CustomerForm(ModelForm):
phone = forms.CharField(required=True,widget=USPhoneNumberWidget())
class Meta:
model = Customer
fields = ('fname','lname','address1','address2','city','state','zipcode','phone')
在模型中,空白和空值不正确。非常感谢任何输入。谢谢
