Question

当我的文本字段中的IP列表进入“ip_list_coices”而不是将每个IP作为一行选择时，我遇到了问题。

IP需要是单独的选择。我觉得这可能是一个简单的修复，但似乎无法弄明白。

以下是示例：

这就是：

192.168.1.2 192.168.1.3 ... 192.168.1.5

这就是我的意愿：

192.168.1.2

192.168.1.3

...

192.168.1.5

models.py

#IP Block Class
class IP_block(models.Model):

#ip block and range save function


def save(self, *args, **kwargs):

    slash = unicode(self.slash)

    self.broadcast_ip = broadcast
    self.subnet = subnet


    #rangeip for loop

    ip = IP(self.network + slash)


    for rangeip in ip[2:-1]:
        self.ip_range += "%s \n" %rangeip

    super(IP_block, self).save(*args, **kwargs)


network = models.IPAddressField(unique=True)
slash = models.ForeignKey(Subnet, verbose_name='CIDR')
subnet = models.CharField(max_length=64, blank=True)
gateway_ip = models.CharField(max_length=64, blank=True)
broadcast_ip = models.CharField(max_length=64, blank=True)
ip_range = models.TextField(blank=True, verbose_name='Available IP Range')
dslam = models.ManyToManyField(Dslam, verbose_name='Dslam', blank=True)
ip_list = models.CharField(max_length=128, blank=True)

class Meta:
    verbose_name_plural = 'IP Blocks'

def __unicode__(self):
    return self.network

forms.py.

class IP_blockForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(IP_blockForm, self).__init__(*args, **kwargs) if self.instance and self.instance.ip_range: #This is where I pass the list from the text field ip_list_choices = [(self.instance.ip_range, self.instance.ip_range ),] self.fields['ip_list'] = forms.ChoiceField(choices=ip_list_choices) class Meta: model = IP_block

Answer 1

您可以这样做：

split_range = self.instance.ip_range.split(' ') #Or whatever your delimiter is
ip_list_choices = zip(split_range, split_range) #Gives you a tuple. 
self.fields['ip_list'] = forms.ChoiceField(choices=ip_list_choices)
