Question

我正在Django中创建简单的网站，我是一个初学者。现在我正在创建注册和登录选项，但是身份验证对我不起作用（我知道这是因为在logging_in.html中没有显示用户名）。

views.py

from django.shortcuts import render, render_to_response, get_object_or_404, redirect
from django.http import HttpResponse
from django.contrib import auth
from django.contrib.auth import authenticate, login
from django.template.context_processors import csrf
from django.http import HttpResponseRedirect
from django.template import RequestContext
from MySite.forms import RegistrationForm
from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth.models import User

def register_user(request):
    if request.method == 'POST':
        form = RegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('register_success')

    args = {}
    args.update(csrf(request))

    args['form'] = RegistrationForm()
    return render_to_response('register_user.html', args)

def register_success(request):
    return render_to_response('register_success.html')

def login_user(request):
    login_user = {}
    login_user.update(csrf(request))
    return render_to_response('login_user.html', login_user)

def auth_view(request):
    username = request.POST.get('username', '')
    password = request.POST.get('password', '')
    user = auth.authenticate(username=username, password=password)

    if user is not None:
        auth.login(request, user)
        return redirect('logged_in')
    else:
        return HttpResponseRedirect('invalid_login')

def logged_in(request):
    return render_to_response('logged_in.html',
                              {'full_name': request.user.username})`

urls.py

from django.contrib import admin
from django.urls import include, path
from django.contrib.auth import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('MySite/', include('MySite.urls')),
    path('accounts/', include('django.contrib.auth.urls')),

MySite.urls.py

    path('login_user', views.login_user, name='login_user'),
    path('authorized', views.auth_view, name='authorized'),
    path('logout', views.logout, name='logout'),
    path('logged_in', views.logged_in, name='logged_in'),
    path('invalid_login', views.invalid_login, name='invalid_login'),

logged_in.html

{% extends "base.html" %}

{% block content %}

    <h2>Hello {{full_name}}, you are logged! </h2>
    <p>Kliknij <a href= "{% url 'logout' %}">tutaj</a> aby się wylogować.</p>
    {% if user.is_authenticated %}
            <a href="{% url 'logout' %}">logout</a>
    {% else %}
            <a href="{% url 'login_user' %}">login</a> / <a href="{% url 'register_user' %}">register</a>
    {% endif %}

我按照教程中的说明进行操作，但是它不起作用。也许有人可以帮助我？是Django 2.2.9

您没有在注册视图中登录用户。这是登录用户的方法：
