Question

forms.py

class PhoneForm(forms.ModelForm):         
    number1 = forms.IntegerField(required=False,error_messages={'invalid':'Enter a valid phone number'})
    number2 = forms.IntegerField(required=False,error_messages={'invalid':'Enter a valid phone number'})
    number3 = forms.IntegerField(required=False,error_messages={'invalid':'Enter a valid phone number'})
    class Meta:
        model = PhoneInfo
        fields = ['name1','number1','name2','number2','name3','number3','emergency','emergency_number']

models.py

class PhoneInfo(models.Model):    
    user = models.ForeignKey(User, null=True)
    name1 = models.CharField('Name', max_length=100, null=True, blank=True)
    number1 = models.CharField('Number',max_length=20, null=True, blank=True)
    name2 =  models.CharField('Name', max_length=100, null=True, blank=True)
    number2 = models.CharField('Number', max_length=20, null=True, blank=True)
    name3 = models.CharField('Name', max_length=100, null=True, blank=True)
    number3 = models.CharField('Number',max_length=20, null=True, blank=True)
    emergency = models.CharField('Emergency', max_length=100, null=True, blank=True)
    emergency_number = models.CharField('Emergency Number',max_length=20, null=True, blank=True)

nmber1，number2和number3用于保存11位电话号码。我的问题是如果我在保存'0'之后将第1位添加为'0'从表格字段中消失。我在之后添加“0”保存和显示的第一个数字。问题是：08854215452保存后第一个零消失。我想在保存带有STD代码的电话号码的同时显示。

Answer 1

永远不要将电话号码保存为IntegerFields。您所看到的行为对于任何编程语言中的整数都是正常的。

>> myInt = 00001
>> print myInt
>> 1

你应该把它存储为什么？您要么a）编写自己的字段，b）选择CharField或选择RegexField

说到phonenumbers我通常更喜欢正则表达式字段如果你在世界的一个固定区域，瑞典就会有以下正则表达式：< / p>

phone_number = forms.RegexField(regex=r'^\+?(\d{3}-?\d+{7})$', error_messages = {'invalid_phonenumber': _("Not a valid Swedish phone number.")}

Answer 2

永远不要将电话号码视为整数！始终使用CharFields，如有必要，可以进行一些验证。确保您不仅允许数字，还包括“ - ”，“”等。

您的ModelForm可能如下所示：

class PhoneForm(forms.ModelForm):
    class Meta:
        model = PhoneInfo
        fields = ['name1','number1','name2','number2','name3','number3','emergency','emergency_number']

    def clean_number1(self):
        n = self.cleaned_data.get('number1')
        for allowednondigit in '- ./':
            n.replace(allowednondigit, '')
        for char in n:
            if char not in '0123456789':
                raise forms.ValidationError("Please only use digits, spaces, dots, slash and dash characters")
        return n

这样，您只会在数据库中存储数字（如果这是您真正想要的数字），同时仍然让您的用户按照他习惯的方式编写电话号码。

Answer 3

由于这个原因，我只看到models.CharField中存储的电话号码。

不要在表单上使用forms.IntegerField，而是使用forms.CharField。

Answer 4

是 - 整数将忽略前导零。您可以将0设为隐式（实际上它是隐式的）或将其转换为文本字段。

Answer 5

我发布了基于mawimawi's answer的工作解决方案。

class PhoneForm(forms.ModelForm):
    class Meta:
        model = PhoneInfo
        fields = ['name1','number1','name2','number2','name3','number3','emergency','emergency_number']

    def clean_number1(self):
        n = self.cleaned_data.get('number1')
        allowed_characters = '0123456789- ./'
        for char in n:
            if char not in allowed_characters:
                raise forms.ValidationError("Please only use digits, spaces, dots, slash and dash characters")
        return n

整数字段前缀零不显示
