NoReverseMatch at /account/login/ (Trying to use Class based authentication views) - django

I am trying to use Django's class based authentication views and am getting the following error when attempting to access the login view:
NoReverseMatch at /account/login/
Reverse for 'register' not found. 'register' is not a valid view function or pattern name.
Error during template rendering
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:

Note sure if this is needed but the account/views.py with the dashboard view:

{'section': 'dashboard'})
and dashboard.html:

{% block content %}
<h1>Dashboard</h1>
<p>Welcome to your dashboard.</p>
{% endblock %}
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.

Logout link not working django

In urls.py I have the following
from django.conf.urls import url
from django.contrib.auth.views import logout
from core import views as core_views
urlpatterns = [
url(r'^logout/$', logout, {'template_name': 'core/logout.html'}, name='logout'),
url(r'^profile/$', core_views.view_profile, name = 'view_profile'),
etc...
]
I have a base.html that is included on every page:
<!doctype html>
<head>
{% block head %}
<title>base</title>
{% endblock %}
</head>
<body>
<a href = 'core/logout.html'>Logout</a>
{% block body %}
{% endblock %}
</body>
</html>
The profile.html page:
{% extends 'core/base.html' %}
{% block head %}
<title> Profile</title>
{% endblock %}
{% block body %}
<h2>Profile</h2>
<p>
{{ user.first_name }}<br/>
{{ user.last_name }}<br/>
{{ user.email }}<br/>
{{ user.userprofile.city }}
</p>
{% endblock %}
The logout.html page:
{% extends 'core/base.html' %}
{% block head %}
<title>Logout</title>
{% endblock %}
{% block body %}
<p>Logged out</p>
{% endblock %}
The problem is if the user is at /profile and clicks the logout link at the top of the page it sends the user to /profile/logout which does not exist, how do I get it to send the user to /logout ?
Instead using:
<a href = 'core/logout.html'>Logout</a>
you should use
Logout

Django, trying to change the class attribute of an extended nav bar

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 !

request.user.first_name does not working in django

I'm trying to build a authentication based view! My html code is:
{% load staticfiles %}
<!DOCTYPE html>

{% if request.user.is_authenticated %}
Hello {{ request.user.first_name }}, Logout
{% else %}
Log-in
{% endif %}
</span>
</div>
</body>
</html>
Here the line:
request.user.first_name
supposed to show the logged in username according to Django By Example book.
also when I'm changing the password in firefox it shows this massage:
But in chrome it works fine in changing password, although the name is not showing in both browser!
My Login page html code is :
{% extends "base.html" %}

{% block content %}
<h1>Log-in</h1>
{% if form.errors %}
<p>
Your username and password didn't match.

I'm stuck really bad :(
This is silly! The problem was I didn't set the user's firstname!
But the second problem is still happening!
i had same issue, but after some research, i found this solution
so try to edit the variable from {{ request.user.first_name }} TO {{ request.user.username}}, so is username not firstname.

Django http404 error urlconf confusion

I was really confused why I was receiving Http404 error. To be more clear heres my code:
My app named books
views.py
from django.shortcuts import render_to_response
from django.http import Http404
from django.template import RequestContext
from books.models import *
def index(request):
title = 'Book Gallery'
books = Book.objects.all().order_by('-id')
lang_list = Lang.objects.all().order_by('-lang')
template = 'books/index.djhtml'
context = {'books': books, 'title': title, 'lang_list': lang_list}
return render_to_response( template, context, context_instance=RequestContext(request) )
def by_book_slug(request, bookslug):
slug = bookslug
try:
book = Book.objects.get(slug=slug)
except:
raise Http404
title = book.name
template = 'books/singlebook.djhtml'
context = {'book': book, 'title': title}
return render_to_response( template, context, context_instance=RequestContext(request) )
def by_lang_slug(request, langslug):
filter = langslug
try:
language = Lang.objects.get(slug=filter)
except:

lang_list = Lang.objects.all().order_by('-lang')
books = Book.objects.filter(lang=language).order_by('-id')
title = language
template = 'books/by_language.djhtml'
context = {'books': books, 'title': title, 'filter': filter, 'lang_list': lang_list}
return render_to_response( template, context, context_instance=RequestContext(request) )

url(r'(?P<bookslug>.*)/$', views.by_book_slug, name='by_book'),
url(r'^$', views.index, name='book_gallery'),
)
link that pertains to langslug url conf works but those links for bookslug url conf does not work. When I try to switch them down and up, one of them work and the other one is not.
I really don't know what is happening here. Any help will be a great help. Thanks.

I have included a raise Http404 method when specified slug does not match to any query in the database. The thing I was confused about is, when I try to switch langslug and bookslug urlconf, links that are associated to one of these url works and the other is not.
Based on your url, if I put value on it even though they have different view, the result would be:
urlpatterns = patterns('',
# http://localhost:8000/English/
url(r'(?P<langslug>.*)/$', views.by_lang_slug, name='by_lang'),
# http://localhost:8000/YourBook/
url(r'(?P<bookslug>.*)/$', views.by_book_slug, name='by_book'),
# http://localhost:8000/
url(r'^$', views.index, name='book_gallery'),
)
Have you notice it, they have the same pattern so the first view execute is the by_lang_slug. So if you change the order the other one will be executed first. The best thing to do about it is to have a unique url name.
urlpatterns = patterns('',
# http://localhost:8000/lang/English/
url(r'lang/(?P<langslug>.*)/$', views.by_lang_slug, name='by_lang'),
# http://localhost:8000/book/YourBook/
url(r'book/(?P<bookslug>.*)/$', views.by_book_slug, name='by_book'),
# http://localhost:8000/
url(r'^$', views.index, name='book_gallery'),
)
Now they are different....

Resetting Password in Django

I have problem in resetting password in Django . After looking at this:Resetting Password, this error still exist....
My error is:

Not sure how to solve this. Need some guidance...
Password Reset
Django has a built-in password reset functions which we are going to use. In this tutorial we will name our app as accounts.
urls.py
from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
admin.autodiscover()
urlpatterns = patterns('',
url(
r'^admin/',
include(admin.site.urls)
),
#this is the url for password reset authentication
#Don't remove, this is important!
url(
r'^account/',
include('django.contrib.auth.urls')
),
#this is the accounts app main url
url(
r'^accounts/',
include('accounts.urls', namespace="accounts")
),
)+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
urlpatterns += staticfiles_urlpatterns()
urls.py
from django.conf.urls import *
urlpatterns = patterns('accounts.views',
url(
r'^forgot-password/$',
'forgot_password',
name="forgot-password"
),
)
views.py
from django.contrib.auth.views import password_reset
from django.shortcuts import render
def forgot_password(request):
if request.method == 'POST':
return password_reset(request,
from_email=request.POST.get('email'))
else:
return render(request, 'forgot_password.html')
Put your base.html in your main templates folder
base.html
<html>
<head>
<title>{% block title %}{% endblock title %}</title>
</head>
<body>
{% block content %}{% endblock content %}
</body>
</html>
put this template in the app templates folder.
forgot_password.html
{% extends "base.html" %}
{% block title %}Forgot Password{% endblock title %}
{% block content %}
<form method="post" action="{% url django.contrib.auth.views.password_reset %}">
{% csrf_token %}
<p>Please enter your email address.
You will receive a link to create a new password via email.</p>
<input type="email" name="email"
placeholder="Your e-mail"><br/>
<button type="submit">Send new password</button>
</form>
{% endblock content %}
settings.py
#add email settings
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'user'
EMAIL_HOST_PASSWORD = 'password'
DEFAULT_FROM_EMAIL = 'your email'
Now we will override the password reset templates of the admin. In your main templates folder create registration folder. Inside the registration folder, create these files:
If you want to change the contents of the files. Make sure it is correct or else you will got an errors.
password_reset_complete.html
{% extends "base.html" %}
{% block title %}Password reset complete{% endblock title %}
{% block content %}

<h4>Set New Password</h4>
<form action="" method="post">

{% if validlink %}
<p>Please enter your new password twice.

<p>
{{ form.new_password1.errors }}<br/>
{{ form.new_password1 }}
</p>
<p class="button-height">
{{ form.new_password2.errors }}<br/>
{{ form.new_password2 }}
</p>
{% else %}
<h4>Password reset unsuccessful</h4>
<p>The password reset link was invalid,
possibly because it has already been used.

{% endif %}
<button type="submit">Change my password</button>

{% endblock content %}
#password_reset_ email.html
{% load i18n %}
{% load url from future %}
{% autoescape off %}
{% blocktrans %}
You're receiving this e-mail because you requested
a password reset for your user account at {{ site_name }}.
{% endblocktrans %}
{% trans "Please go to the following page and choose a new password:" %}
{% block reset_link %}
{{ protocol }}://{{ domain }}{% url 'django.contrib.auth.views.password_reset_confirm' uidb36=uid token=token %}
{% endblock %}
{% trans "Your username, in case you've forgotten:" %} {{ user.username }}
{% trans "Thanks for using our site!" %}
{% blocktrans %}The {{ site_name }} team{% endblocktrans %}
{% endautoescape %}
password_reset_form.html
{% extends "base.html" %}
{% block title %}Password reset form{% endblock title %}
{% block content %}
<h4>Reset Password</h4>
<p>Forgotten your password?
Enter your e-mail address below,
and we'll e-mail instructions for setting a new one.</p>
<form action="" method="post">
{% csrf_token %}
{% if form.email.errors %}`enter code here`
<div class="message red-gradient">{{ form.email.errors }}</div><br/>
{% endif %}
<p>E-mail address: {{ form.email }} <br/><br/>
<input type="submit" value="Reset my password"></p>
</form>
{% endblock content %}
Than your def lexresetpasswordconfirmed(request): should accept also uidb36 and token args.
Reverse for 'django.contrib.auth.views.password_reset_confirm' with arguments '()' and keyword arguments '{'uidb36': '1', 'token': '392-804fab6dcec790f0ec6b'}' not found.
This means that at some point in the execution, you are not calling reverse on lexresetpasswordconfirmed, you are calling it on django.contrib.auth.views.password_reset_confirm.
Where is this error occurring? In the template? If so, make sure that the template you are using has
{% url lexresetpasswordconfirmed uid token %}
and not
{% url django.contrib.auth.views.password_reset_confirm uid token %}
Is the error occurring in a view? If so, somewhere you are calling reverse on django.contrib.auth.views.password_reset_confirm.
Once that error is resolved, then yes you will have to resolve the other error that Alexander pointed out, namely including the uuid and token in the view function:
#login_required
def lexresetpasswordconfirmed(request, uuid36, token):
"""
Reset Password Confirmed
"""
# you need to do SOMETHING with the uuid and token here, RIGHT?!?!
path = reverse('lexresetpasswordcompleted')
return password_reset_confirm(request,post_reset_redirect=path)
So I'm guessing on each of these returns you're using the views from django.contrib.auth, correct? Problem is that one of these views -- probably password_reset_done -- doesn't care that you've provided it with a redirect, it's using its own.
