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.

In our process of upgrading our Django project from 1.8 to 1.9 version, we removed all the deprecation warnings/errors according to Django-1.9 release notes.
But, after updating the Django version to 1.9 in the project's virtual environment, we got the following error:

We have many installed apps in the project and using PostgreSQL-9.5 database. We know that the apps which have model classes in it, cause this error to occur.
The above error even occured when connecting to the database using
connection cursor:
django.db.connection.cursor().execute()
Why do I get this exception?

It only happens if I call the unittest via PyCharm, not if I use py.test on the shell.
I guess reverse_lazy() is not lazy here, since it gets used in format_html(). Any way to have a lazy format_html()?
Versions:
Django 1.8
Pycharm 5.0.4
Since there are things like url_patterns in the stacktrace, I assume that DJANGO_SETTINGS_MODULE is set correctly .
But, you still need to call django.setup() before running anything else.
import django
django.setup()
For me, that made this error message go away.
I've had some trouble using PyCharm, myself, and I'll assume you're using the the community edition (which I've been using).
If so, the problem is very likely that you're not properly configured for django. You can probably fix this with some hacks that might work for this.
I'd start off with this.
(importing django to ensure the django console is run)
Then maybe this.
There's also this:
Check "Edit Configurations" under the test you're running, and add DJANGO_SETTINGS_MODULE=<app-name-here>.settings to environment variables.
If all of the above fails, try initializing your form and doing the import in the constructor:
class ISUSearchForm(...):
...
foo_filter = forms.Field()
...
def __init__(*args, **kwargs)
from ... import reverse_lazy
from ... import FooFilter
self.fields['foo_filter'] = \
forms.ModelChoiceField(
FooFilter.objects.all(),
label=format_html(
'%s',
reverse_lazy('foo-filter'),
FooFilter._meta.verbose_name
)
)
super().__init__(*args, **kwargs)
The error may be caused by the exact import sequence performed by the different test runners and the fact that you use only class variables to customize your form.
In django 1.8, reverse() and reverse_lazy() now return Unicode strings instead of byte strings.

Since I'm new in django and it's my first project, Every hint would be appreciated. ths in advance.
It looks like you might be using a version of Django registration that does not support Django 1.8. You could try installing Django registration redux instead.

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.
I followed the steps here https://developers.google.com/cloud-sql/docs/django and it ran well with django 1.3.1. Now up to Django 1.4 and gives a funny stack trace. I would paste the relevant part of the message here

Error was: cannot import name Thing2Literal
Any help? Some one said it needs to be compiled http://django-irc-logs.com/2012/mar/27/ ?
I had the same issue. Since the problem is with importing Thing2Literal that is used by adapt_datetime_with_timezone_support function from django/db/backends/mysql/base.py and according to this:
https://code.djangoproject.com/changeset/17596/django/trunk/django/db/backends/mysql/base.py this is important only to datetime objects that bypass the model layer and are used with raw sql. So i decided it is not important for me and I messed a bit my django/db/backends/mysql/base.py: comment out code that causes trouble (import of Thing2Literal, adapt_datetime_with_timezone_support function and line 83 where the function is called)
Of course I upload my django 1.4 customized that way to appengine together with my project and it works.
I would appreciate feedback from those who understand django internals better, whether what i've done is ok assuming i don't use raw sql at all.
As you can see in the documentation you've linked, Google App Engine support only Django up to version 1.3 (actually 1.3.1).
