How to correctly redirect the user to the main page after login and logout in Django?

Question

Django

Good day to all, dear members of the forum!) I
started learning Django just recently, I got the idea to make a simple blog for a start, where the main page will immediately display a list of articles from the database, sorted by date (i.e. when you click on the link my_site.ru / the main_views.index view immediately fires , which loads all the articles into the
template logout in Django? here is the project structure: my_project | |--- articles | |--- accounts


code my_project/urls.py

from django.contrib import admin
from django.urls import path, include
from . import views as main_views
from django.conf.urls.static import static
from django.conf import settings


urlpatterns = [
    path('', main_views.index),
    path('admin/', admin.site.urls),
    path('articles/', include('articles.urls')),
    path('accounts/', include('accounts.urls')),
]

accounts/urls.py code

from . import views
from django.urls import path

urlpatterns = [
    path('login', views.login), 
    path('logout', views.logout,
]

accounts/views.py code

from django.shortcuts import render, redirect
from django.contrib import auth

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


def logout(request):
    auth.logout(request)
    return render(request, 'index.html')
]

here is a piece of the index.html template with the form

{% if user.is_authenticated %}
     <div class="user"> Привет, {{ user.get_full_name }}!
         <form action="accounts/logout" method="post"> {% csrf_token %}
              <input type="submit" value="Выйти" />
         </form>
    </div>
{% else %}
   {% if form.errors %}
         <p class="error">Сожалеем, вы неправильно ввели логин или пароль</p>
   {% endif %}
   <form action="accounts/login" method="post">{% csrf_token %}
       <label for="username">Логин:</label>
       <input type="text" name="username" value="" id="username">
       <label for="password">Пароль:</label>
       <input type="password" name="password" value="" id="password">

       <input type="submit" value="login" />
       <input type="hidden" name="next" value="{{ next }}" />
    </form>
{%  endif %}

when authorizing the user, it redirects to the main page, which is logical, because I render the main template and the articles are not displayed, which is also kind of obvious, because the necessary view is not called) so how to call it correctly? you can connect the index view from my_project/views.py to accounts/views.py , but I feel in one place that this is not comfortable because cross-links are created, and this is not flexible)) and more .... after the user decides to log out and clicking on the logout button gives an error

Page not found (404)
Request Method:	POST
Request URL:	http://127.0.0.1:8000/accounts/accounts/logout

here I can’t understand at all why this is so ... why the appeal goes 2 times to accounts

Use the url tag in your templates and return a response with redirect in login/logout
