设置用户时在django视图中请求错误

Question

我有一个应用程序可以让当前登录的用户创建一个 Person 对象。该人对象将当前登录的用户作为其所有者。但是当我保存表格时它给了我以下错误

global name 'request' is not defined

我正在尝试使用 Django CreateView

来实现这一点

    person_last_name = models.CharField("last Name", max_length=25)

    person_address = models.CharField("Address", max_length=512)

    person_email = models.EmailField("Email", max_length=512)

    person_contact_number = models.PositiveIntegerField("Phone Number", blank=True, null=True)

    person_members = models.PositiveSmallIntegerField(
        "Family members", blank=True, null=True)

我无法理解为什么这个错误甚至首先发生，因为我认为 request 在 Django

中无处不在

Answer 1

以及您使用的是 Class Based View

您要使用的所有参数或变量都需要自己附加到它

所以，

obj.user_relation = self.request.user

self代表instance of the class。通过使用 “self” 关键字，我们可以访问 的属性和方法 ]class。它将属性与 给定参数 绑定。
