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 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:
account/urls.py:
from django.urls import path
from . import views
from django.contrib.auth import views as auth_views
urlpatterns = [
path('', views.dashboard, name = 'dashboard'),
path('login/', auth_views.LoginView.as_view(), name = 'login'),
path('logout/', auth_views.LogoutView.as_view(), name = 'logout'),
]
login.html:
{% extends "base.html" %}
{% block title %}Log-in{% endblock %}
{% block content %}
<h1>Log-in</h1>
{% if form.errors %}
<p>
Your username and password didn't match.
Please try again.
</p>
{% else %}
<p>Please, use the following form to log-in. If you don't have an account register here</p>
{% endif %}
<div class="login-form">
<form action="{% url 'login' %}" method="post">

{% csrf_token %}
<input type="hidden" name="next" value="{{ next }}" />
<p><input type="submit" value="Log-in"></p>
</form>

Note sure if this is needed but the account/views.py with the dashboard view:
from django.contrib.auth.decorators import login_required
#login_required
def dashboard(request):
return render(request,
'account/dashboard.html',
{'section': 'dashboard'})
and dashboard.html:
{% extends "base.html" %}
{% block title %}Dashboard{% endblock %}
{% 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.
I am trying to use the Django authentication views. My login/logout views are working without a problem.
urls.py:
from django.urls import path
from django.contrib.auth import views as auth_views
from account import views
urlpatterns = [
path('', views.dashboard, name = 'dashboard'),
path('login/', auth_views.LoginView.as_view(), name = 'login'),
path('logout/', auth_views.LogoutView.as_view(), name = 'logout'),
path('password_change', auth_views.PasswordChangeView.as_view(), name = 'password_change'),
path('password_change/done', auth_views.PasswordChangeDoneView.as_view(), name = 'password_change_done'),
]
password_change_form.html:
{% block body %}
<h1>Change your password</h1>
<p>Please use the following form to change your password:</p>
<div class = 'password-change-form'>
<form class="" action="{% url 'login' %}" method="post">
{{ form.as_p }}
{% csrf_token %}
<input type="submit" name="" value="Change">
</form>
</div>
{% endblock %}
password_change_done.html:
{% block body %}
<h1>Password Changed Successfully</h1>
{% endblock %}
I can navigate to /password_change and see the form, but when I fill it in and submit it in I am redirected to /login (I have made sure I was already logged in) and the password does not change. Does anyone know what the issue is?
This is because you specified {% url 'login' %} for the action="…" parameter, you need to change it with:
{% block body %}
<h1>Change your password</h1>
<p>Please use the following form to change your password:</p>
<div class = 'password-change-form'>
<form class="" action="{% url 'password_change' %}" method="post">
{{ form.as_p }}
{% csrf_token %}
<input type="submit" name="" value="Change">
</form>
</div>
{% endblock %}
when I submit my Email form from PasswordResetView page the email appears via URL as following: http://127.0.0.1:8000/account/password-change/?email=medoabdin%40gmail.com and not directing me to PasswordResetDoneView page and I get no error.
how can I show PasswordResetDoneView message page

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.
I'm getting the below error and I have no idea why... I swear everything was working fine yesterday... I'm using python 3.5 and django 1.9. I went through most of the NOReverseMatch posts, but I couldn't find anything... please help

I am having problems running through a tutorial and it seems the problems stem from this:
(r'^l/login/$', 'django.contrib.auth.views.login'),
It seems I have done all correct, but the forms dont show.
If I hit Login. I get back to the same page without forms.
Did I miss something?
Here the code:
urls.py:
from django.conf.urls.defaults import *
from formsapp.views import *
from login.views import *
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
#Forms1:

#Forms2
(r'^register/', main_page1),
#FormsLogin:
(r'^l/', login_main_page),
(r'^l/login/$', 'django.contrib.auth.views.login'),
(r'^l/logout/$', 'logout_page'),

{% if form.has_errors %}
<p> Username or password didn't work. Please enter them again </p>
{% endif %}
<form method="post" action=".">

{% endblock %}
URL pattern
(r'^l/', login_main_page),
will match any URL starting with l/ and it is placed before l/login so second one won't be called, you should terminate regexp with $:
(r'^l/$', login_main_page),
