[メモ]DjangoのLogin、Logout機能

Djangoのログイン機能に少し引っかかってしまったので、メモします。
startappはDjangoで作成したアプリ内という意味です。

startapp/urls.py

from django.urls import path
from .views import homefunc, loginfunc, logoutfunc

app_name = 'blog'

urlpatterns = [
    path('', homefunc, name='index'),
    path('login/', loginfunc, name='login'),
    path('logout/', logoutfunc, name='logout'),
]

startapp/view.py

from django.shortcuts import render, redirect,
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.decorators import login_required

@login_required
def homefunc(request):
    return render(request, 'index.html', {})


def loginfunc(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(request, username=username, password=password)
        if user is not None:
            login(request, user)
            return redirect('blog:index')
        else:
            return render(request, 'login.html', {})

    return render(request, 'login.html', {})


def logoutfunc(request):
    logout(request)
    return redirect('blog:login')

setting.py

LOGIN_URL = 'blog:login'
LOGIN_REDIRECT_URL = 'blog:index'
