I am trying to use Django's class based authentication views and am getting the following error when attempting to access the login view:

In template /Users/justin/Desktop/Programming/Python/django_book/social/website/account/templates/base.html, error at line 0
All authentication templates are stored at account/templates/registration/ and dashboard.html is stored at account/templates/account/, here is the code:

I am following the book 'Django 2 By Example' and at this point I believe I have directly copy and pasted the code from here (https://github.com/PacktPublishing/Django-2-by-Example/tree/master/Chapter04) to try and fix this error, but I am still getting. I should note that I am using Django 3.2.6 and am not sure if this is causing it. Thanks for any help with this.

There is a typo in your code. In template you are using allposts(all lower case) where you are passing allPosts from context, ie: params = {'allPosts': allPosts}. So you need to change either one of them, like change in context:
params = {'allposts': allPosts}
And one improvement suggestion, replace href="/blog/{{post.slug}}" in the template with href="{% url 'url_name' %}". More information can be found in url tag documentation.

Put method="post" in form tag and also {% csrf_token %}, probably because of GET method same view is rendering and form_valid is not invoking.
This question already has answers here:
Error "Reverse for 'django.contrib.auth.views.login' not found" [duplicate]
(2 answers)
Closed 5 years ago.
NoReverseMatch at /login/ is the error I'm getting from the console, I have a feeling this is something to do with the linking that is going on between urls.py but I can't figure out which part of it is wrong. Any help would be greatly appreciated on this.
The full error from the console is beneath
Reverse for 'django.contrib.auth.views.login' not found.
'django.contrib.auth.views.login' is not a valid view function or pattern name.

Can anyone point out what I'm doing wrong here? I think it's something to do with my urls.py but I can't figure out what, any help would be greatly appreciated
<form id="login-form" method="post" action="">
in login.html
you dont need the action, simply keeping it to post to itself will work
You can either use form with no action or change {% url 'django.contrib.auth.views.login' %} to {% url 'login' %}
By the way, standard login view is deprecated and you will get a warning.
It's better to use LoginView.as_view() or subclass it if you want to change the default template_name (which is 'registration/login.html').
I created a "base.html" template to hold my nav bar and other elements that are recurrent on my website.
When I extend this template and put values into my blocks one of them doesn't want to work properly.
In my code I try to set the class value of my nav element to "active" depending on which page I'm in (it might not be the best solution). This block never works.
Thank you for your help :)

I guess your base.html file is not in the correct folder !
