下拉列表html代码

标签： python html django python-3.x django-models

我想显示某些字段的下拉选项。我有一个模型工作单，并创建了一个模型表单。我创建了一个文件choices.py，并在模型中以及在forms.py中定义了创建的选择，但是我不知道显示选择的html代码。我是一个初学者，因此不胜感激。这是我的代码：我要添加下拉列表的字段是WO_Type_ID。

答案 0 :(得分：0)

您可以在forms.py中删除整个小部件。 您的表格应该是：

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
