在Django中如何使我的模型字段可以选择？ [英] How can I make my model fields optional in Django?

问题描述

我正在尝试按照

https://docs.djangoproject.com/en/dev/topics/auth/customizing/

在我的模型我已修改为以下

In my model I have modified to the following

date_of_birth = models.DateField(null=True)

但是，当我尝试注册用户时，我仍然会收到以下错误消息：

However when I try register a user I still get the following error message:

date_of_birth <ul class="errorlist"><li>This field is required.</li></ul>

在其他哪些地方我需要使date_of_birth可选？

In what other places do I need to make date_of_birth optional?

推荐答案

您必须在字段定义中添加 blank = True 。

You would have to add blank=True as well in field definition.

date_of_birth = models.DateField(null=True, blank=True)

从 modelform doc

如果模型字段为空白= True，则表单字段上的必填项设置为False。否则，required = True。

If the model field has blank=True, then required is set to False on the form field. Otherwise, required=True.

不要忘记在更改此项后重新设置并同步DB。

Don't forget to reset and sync DB again after changing this.
