Django中的登录重定向

我有一个auth系统和django-allauth个库，我有一些登录，注销功能实现，它工作得很好.但我想实现我自己的个人资料页面.对于这一点，我对Django重定向非常困惑.

我有一个名为HomeRequestHandler的基于类的视图，它继承了一个LoginRequiredMixin:

from django.contrib.auth.mixins import LoginRequiredMixin
from django.views.generic import TemplateView


class HomeRequestHandler(LoginRequiredMixin, TemplateView):
    template_name = "home.html"

在我的URL中，我只将其调用为"":

from django.views.generic import TemplateView
from django.urls import path
from . import views

urlpatterns = [
    path("", views.HomeRequestHandler.as_view(), name="home"),
    path("profile/", TemplateView.as_view(template_name="account/profile.html"), name="profile"),
]

在我的settings.py，我有一个LOGIN_REDIRECT_URL的常量:

LOGIN_REDIRECT_URL = reverse_lazy('profile')

当我try 登录时，我被重定向到"/"，即使定义了LOGIN_REDIRECT_URL.但如果我改变一件事在我看来:

from django.contrib.auth.mixins import LoginRequiredMixin
from django.views.generic import TemplateView


class HomeRequestHandler(LoginRequiredMixin, TemplateView):
    template_name = "home.html"
    redirect_field_name = "redirect_to"

它将我的urlhttp://localhost:8000/accounts/login/?next=/更改为http://localhost:8000/accounts/login/?redirect_to=/，现在常量正常工作，为什么？
