How to check whether a user is online in django template?
but when adding
'userprofile.middleware.ActiveUserMiddleware', to MIDDLEWARE_CLASSES
recieving next error:

Thx for help.
May be someone advise how to make check for online/offline users in Django 1.10

Just created a project, added app definition in settings.py, and created an app with a urls.py file seperately and tried to include the urls.py file in the main urls.py file that is created by default when we create a project and tried to return a HttpResponse in a seprate file.

I believe the error message is pretty clear:
The included URLconf <module 'hello.urls' from 'C:\Users\Sujit\Documents\CS50\lecture3\hello\urls.py'> does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
Make sure this file contains a variable named urlpatterns, and that you can succesfully import it.
I followed the instructions on https://github.com/defrex/django-encrypted-fields but importing still doesn't work.
I tried adding encrypted_fields/django_encrypted_fields/django-encrypted-fields to INSTALLED_APPS in settings.py but none of those work.
How can I fix this?
Thanks!
Thanks to #Alasdair for the tip:
I installed django-encrypted-fields in the wrong virtualenv. Uninstalled it, installed it in the correct one and it imports.
However, now I'm having the same issue with keyczar, which I re-installed with django-encrypted-fields into the right virtualenv. Here is the full traceback:

I'm trying to add django-seo into my site. But I can't cope with setting up. I followed instructions documentation, but error occurs.
This is what I did:
Installed django-seo packacge
Added rollyourown.seo to INSTALED_APPS
Created seo.py file in my site content app
And this is what I wrote into seo.py file:
from rollyourown import seo
class Metadata(seo.Metadata):
title = seo.Tag(head=True, max_length=68)
description = seo.MetaTag(max_length=155)
keywords = seo.KeywordTag()
heading = seo.Tag(name="h1")
class Meta:
seo_views = ('SiteContent',)
seo_models = ('SiteContent',)
When Meta class is removed, I can't add any meta tags to contnet via Django Admin Site( I registered it in admin site ). I've read that django-seo use get_absolute_url() to deal with it. But in my site app I don't use this function for provide more some utilities to multilanguage.
But if i add Meta class, i will get this error:

I tried diffrent solutions but nothing helped.
Django-SEO is not compatible with Django 1.7, which is the first version of Django that includes the AppRegistry.
Either rollback to Django 1.6.x or remove Django-SEO.
I got it working by changing get_query_set() to get_queryset()(changed in django1.8) in file rollyourown\seo\backends.py
As original Django-SEO is not supported anymore, these guys made and support their own version / fork of Django-SEO. I use it with Django 1.8.8, Python 3 is supported too.

django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.
from this code (models.py):
# Serializers for transmitting CMx install information over HTTP
class BrzSerializer(serializers.ModelSerializer):
class Meta:
model = Brz
fields=('filename',)
class VersionSerializer(serializers.ModelSerializer):
brzs= BrzSerializer(many=True)
class Meta:
model = Version
fields=('name', 'for_mac', 'for_windows', 'brzs')
It sounds like it's telling me "your VersionSerializer can't have a BrzSerializer, because you haven't registered that yet".
I've looked at other SO questions relating to AppRegisteryNotReady, but didn't find one that matches this symptom. Surely I have to be able to define a chain of dependent models like this?
It turns out that having the declaration of the serializers inside models.py is causing that application to be used before the app registry has finished being loaded.
models.py is actually the wrong place to declare these serializers (though I'm 99% certain I did it that way based on an example of how to use them).
The fix is to move the declaration of the serializers out into their own file (which makes sense, because they have nothing to do with the database schema, which models.py is defining), and import that from the view. By the time the view gets going, the app registry is ready.

If i don't have any issue with using gravatar if i don't use the add_to_builtins functionality - that is, with plain old load tags in my views. I'm just using it a fair bit, so thought i might make use of the add_to_builtins functionality.
From the looks of things, the imported version crashes because the import_library(module) for gravatar.gravatar returns None (i know this because i printed out that line, and it returns None) - what is wrong with what i've done?
oh gravatar.
Ok, so i was all wrong in how to import this using the add_to_builtins - what i needed to do was:
add_to_builtins('gravatar.templatetags.gravatar')
i'm unsure as to why, but that works a treat. Now i don't need to have any messy "load" statements, and i can happily call
{% gravatar story.user 40 %}
from any of my templates. yay!
