python - 子类化基本 Django 通用 View 时缺少 META 属性？

Question

我正在尝试对 Django 提供的基本通用 View 对象进行子类化，以便我可以完全控制 View 的渲染，但仍然使用更清晰的基于类的 View 方法，而不是映射到函数。

这是我到目前为止的观点:

from django.views.generic.base import View
from django.shortcuts import render
from account.forms import UserForm, UserProfileForm

class RegisterView(View):    
    def get(request, *args, **kwargs):

        user_form = UserForm()
        profile_form = UserProfileForm()

        return render(request, 'account/register.html', {'user_form': user_form, 'profile_form': profile_form})

    def post(request, *args, **kwargs):
        pass

当我尝试导航到此 View 的 URL 时，我从 Django 收到此错误:

AttributeError at /account/register/

'RegisterView' object has no attribute 'META'

Request Method:     GET
Request URL:        http://localhost:8000/account/register/

在对通用 View 进行子类化时，文档没有指定任何有关任何“META 属性”的信息，因此我不确定我做错了什么，或者这是否是基本通用 View 的允许使用。

我对(严肃的)Python 编程和 Django 有点陌生，所以如果我遗漏了一些明显的内容，请原谅我。

记住这是一个类:您错过了 get 和 post 定义中的 self 参数:

def get(self, request, *args, **kwargs):
