adding a url in django-template - django

i tried to add a url in django template which is supposedly to log out a user
<div>logout</div>
but it threw a NoReverseMatch
the template:
<header class="grid-header header">
<div class='logo-text'>Nitro fleet</div>
<div class="profile-detail">
{% if user.is_authenticated %}
<img class="profile-img" src="{{user.picture.url}}" />
<div>
<div>{{user.username}}</div>
<div>logout</div>
</div>
{%endif%}
</div>
</header>
the url of the app (accounts) that has the logout view:
from django.urls import path
from . import views
appname = 'accounts'
urlpatterns = [
path('register', views.register_view , name='user_register'),
path('login', views.user_login , name='user_login'),
path('logout', views.user_logout , name='user_logout'),
]
the view function:
def user_logout(request):
logout(request)
return HttpResponseRedirect(request.path_info)
the complete error log:
NoReverseMatch at /maintenance/

Just use the name of the view:
{% url 'accounts:user_logout' %}

NoReverseMatch in Django for username pass to view

I'm working on a basic Django app (just learning, this is my third small project), and I'm trying to add links to allow a list of every post a user has made. I've got the URLS being created OK (domain/posts/username), and I want this to link to a view (that I've already created, and which works when the parameters I want to pass are hard-coded to a single value), passing the positional arguments to the view. However, I'm running aground on the RegEx / Urls part of things. I think this is the relevant info:
urls.py:
urlpatterns = [
url(r'^create/', views.create, name='create'),
url(r'^(?P<pk>[0-9]+)/upvote', views.upvote, name='upvote'),
url(r'^(?P<pk>[0-9]+)/downvote' , views.downvote, name='downvote'),
url(r'^userposts/(?P<user>[.]+)', views.userposts, name='userposts')
views.py
def userposts(request,user):
posts = models.Post.objects.filter(url__contains=user)
return render(request, 'posts/userposts.html', {'posts': posts})
home.html
a href="{{ post.url}}">{{ post.title }}</a><br/>{{ post.pub_date_pretty }} by
{{ post.author.username }}</td>
With the (?P[.]+) part of the last url line removed, the page will render OK, but the links don't work (as there's no user parameter being passed). With the regex present (not only this one, but the many others I've tried), I get a NoReverseMatch error:
NoReverseMatch at /

Your userposts is defined like
url(r'^userposts/(?P<user>[.]+)', views.userposts, name='userposts')
which means it requires a user argument to resolve.
To pass such an argument, you'd do
{% url 'posts:userposts' user_goes_here %}
Try this instead
{{ post.author.username }}

NoReverseMatch on password_Reset_confirm

django password reset NoReverseMatch error
I'm following tutorial from http://code.techandstartup.com/django/reset-password/ ==> customized Templates.
Instead of referencing the view, you need to just reference the name of your url pattern that you are trying to match
{% url 'password_reset_confirm' uidb36=uid token=token %}

NoReverseMatch in render_to_response with django-social-auth

I would like to make just a page that has link to login to twitter/facebook/google with django-social-auth.
but I get a error NoReverseMatch: Reverse for '' with arguments '(u'twitter',)' and keyword arguments '{}' not found.
def index(request):
ctx = {}
return render_to_response('index_before_login.html', {}, RequestContext(request))
index_before_login.html is following
<li>Enter using Twitter</li>
urls.py is following
urlpatterns = patterns('',
url(r'^$', 'lebabcartoon.views.index'),
#url(r'^socialauth_', 'lebabcartoon.views.index'),
url('', include('social_auth.urls')),
my environment is
Django ver1.5
Python Version: 2.7.3
django-social-auth: 0.7.5
anyideas?
Wrap url name in quotes
{% url 'socialauth_begin' 'twitter' %}
To save someone using the new python-social-auth and django > 1.4
Use this :
{% url 'social:begin' 'twitter' %}
I had a similar problem, try adding the following to the url.py file in your project.
url(r'auth/', include('social_auth.urls'))
And also make sure your url parameters are wrapped in quotes like so.
{% url "socialauth_begin" "twitter" %}

Could not parse the remainder Django

I've been trying to write a custom template tag to shorten links with bitly, I've attached the code and error I've been getting below. I've tried to look into the documentation provided by Django but cannot see what it is that I am doing wrong.
I've put my templatetag in the following layout:
scribbler/
models.py
templatetags/
__init__.py
shortenlink.py
views.py
the custom tag file that I've written:
shortenlink.py
from django import template
from django.conf import settings
from urllib import urlencode
from urllib2 import urlopen
register = template.Library()
#register.simple_tag
def bitlyshort(the_url):
endpoint = 'https://api-ssl.bitly.com/v3/shorten?access_token={0}&longUrl={1}&format=txt'
req = urlencode(endpoint.format(settings.ACCESS_KEY, the_url))
return urlopen(req).read()
part of the template that uses the template tag:
template
{% load shortenlink %}
<p>{{ bitlyshort "http://www.google.com" }}</p>

The error is on this line:

Template tags use {% ... %} (template filters use {{ ... }}). Try:

There is an alternative way to cause this error:

{{ data|filter }}
If you use:
{{ data | filter }} <!-- Note Spaces -->
The spaces on either side of the | character will cause an exception during page render.

What am I doing wrong?
Please help to find the solution.
You are on django 1.3. Have you included the new url template tag with {% load url from future %}. If you have then your syntax for the url tag is incorrect and would need to be {% url 'begin' 'google-oauth2' %}. If you haven't then your syntax is correct.
Have you ensured that your social_auth.urls is being included correctly? To do this (with debug enabled) manually go to http://yourdevserver/login/google-oauth2/ and ensure you don't see a 404 page. If you do you will be able to see what url's where attempted and that should give you direction on how to fix it.
