下拉列表html代码

Question

我想显示某些字段的下拉选项。我有一个模型工单，我创建了一个模型表单。我创建了一个文件choices.py 并在模型和forms.py 中定义了创建的选项，但我不知道显示选项的html 代码。我是初学者，所以会很感激任何帮助。这是我的代码：我要创建下拉列表的字段是 WO_Type_ID。

models.py

    WO_ID = models.BigIntegerField(primary_key=True)
    WO_DateDefWO = models.DateField()
    WO_DateSched = models.DateField(blank=True, null=True)
    WO_DateFinished = models.DateField(blank=True, null=True)
    WO_ST_ID_Sign = models.BigIntegerField(blank=True, null=True)
    WO_Status_ID = models.BigIntegerField(blank=True, null=True)
    WO_Type_ID = models.BigIntegerField(blank=True, null=True, default=1, choices=TYPE_CHOICES)
    WO_Comments = models.CharField(max_length=254, blank=True, null=True)
    WO_Nav_ID = models.BigIntegerField(blank=True, null=True)
    WO_Nav_Kons_ID = models.CharField(max_length=12, blank=True, null=True)
    WO_Nav_Name = models.CharField(max_length=254, blank=True, null=True)
    WO_Nav_CustAdr = models.CharField(max_length=254, blank=True, null=True)
    WO_Nav_Debt = models.FloatField(blank=True, null=True)
    WO_Nav_PropCode = models.CharField(max_length=254, blank=True, null=True)
    WO_Nav_DepCode = models.CharField(max_length=254, blank=True, null=True)
    WO_Nav_PhoneNo = models.CharField(max_length=254, blank=True, null=True)
    WO_Nav_ReasonCompl = models.CharField(max_length=254, blank=True, null=True)
    WO_NightShift = models.BooleanField(default=False)
    WO_Priority = models.BigIntegerField(blank=True, null=True)
    WO_RE_ID = models.BigIntegerField(blank=True, null=True)
    WO_MapUrl = models.CharField(max_length=254, blank=True, null=True)

    def __unicode__(self):
        return self.WO_ID

Answer 1

您可以在 forms.py 中删除整个小部件部分 你的表格应该是：

class CreateWorkorder(forms.ModelForm):
class Meta:
    model = models.Workorder
    fields = ['WO_ID', 'WO_DateDefWO', 'WO_Type_ID', 'WO_DateSched', 'WO_Status_ID', 'WO_Nav_ReasonCompl', 'WO_Nav_CustAdr', 'WO_Nav_Name', 'WO_Nav_PhoneNo', 'WO_MapUrl']

由于您在 models.py 中指定了选项，因此 WO_Type_ID 将自动呈现为 html 中的选择标记
