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视图的呈现，但仍然使用更简洁的基于类的视图方法，而不是映射到函数。

到目前为止，这是我的观点：

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

当我尝试导航到此视图的 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/

在子类化通用视图时，文档没有指定任何“META 属性”，所以我不确定我做错了什么，或者这是否是基本通用视图的允许使用。

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东西，请原谅我。

记住这是一个类：你错过了andself定义中的论点：getpost

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