Django modelform 非必填字段 [英] Django modelform NOT required field

问题描述

我有一个这样的表格:

class My_Form(ModelForm):
    class Meta:
        model = My_Class
        fields = ('first_name', 'last_name' , 'address')

如何将地址字段设为可选?

How can I put the address field as optional?

推荐答案

猜猜你的模型是这样的:

Guess your model is like this:

class My_Class(models.Model):

    address = models.CharField()

您的 Django 版本表单 <1.8:

Your form for Django version < 1.8:

class My_Form(ModelForm):

    address = forms.CharField(required=False)

    class Meta:
        model = My_Class
        fields = ('first_name', 'last_name' , 'address')

您的 Django 版本表单 >1.8:

Your form for Django version > 1.8:

class My_Form(ModelForm):

    address = forms.CharField(blank=True)

    class Meta:
        model = My_Class
        fields = ('first_name', 'last_name' , 'address')
