对基本Django泛型视图进行子类化时缺少META属性

Question

我正在尝试对Django提供的基本泛型View对象进行子类化，这样我就可以完全控制视图的呈现，但仍然使用更干净的基于类的视图方法，而不是映射到函数。

这是我目前的看法：

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

当我试图导航到这个视图的URL时，我从Django得到了这个错误：

AttributeError at /account/register/
'RegisterView' object has no attribute 'META'
Request Method:     GET
Request URL:        http://localhost:8000/account/register/

Traceback:

在对泛型视图进行子类化时，文档中没有指定任何关于"META属性"的内容，所以我不确定我做错了什么，也不确定这是否是基本泛型视图的允许使用。

我对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：您在get和post:的定义中错过了self参数

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