I'm experimenting with Page extensions and FeinCMS 1.2.1.
I'd like to create this simple page extension:
from django.db import models
def register(cls, admin_cls):
cls.add_to_class(models.TextField())
but I keep getting this error:
AttributeError: 'module' object has no attribute 'TextField'
The package containing the extension is called dev.extensions and the module categories, I have added it to the Python path and the extension is registered with Page.register_extensions('dev.extensions.categories').
I'm wondering what I'm doing wrong, please help.
The complete stacktrace follows.

Maybe models is getting reassigned somewhere to another module before your register function gets run?
Try changing your code to this:
from django.db import models as django_models
def register(cls, admin_cls):
cls.add_to_class('field_name_here', django_models.TextField())

I'm trying to use Django-nested-inlines application but it raises error. Here is a simple code:
MODELS.PY
class Language_Quiz(models.Model):
name = models.CharField(max_length=40)
language = models.OneToOneField(sfl_models.Language)
class Question(models.Model):
language_quiz = models.ForeignKey(Language_Quiz)
text = models.TextField()
class Answer(models.Model):
question = models.ForeignKey(Question,related_name='answers')
text = models.TextField()
correct = models.BooleanField()
ADMIN.PY
from django.contrib import admin
import models
from nested_inlines.admin import NestedModelAdmin, NestedTabularInline
class AnswerInline(NestedTabularInline):
model = models.Answer
class QuestionInline(NestedTabularInline):
model = models.Question
class LanguageQuizAdmin(NestedModelAdmin):
inlines = [QuestionInline]
admin.site.register(models.Language_Quiz,LanguageQuizAdmin)
admin.site.register(models.Answer)
admin.site.register(models.Question)
But when I run server or try to make migrations, the error is raised. I have no idea where is the problem. Where is the problem?

As Kapil Sachdev and karthikr commented, the problem is with compatibility. Django-nested-inlines has probably some issues working with Django 1.8+.
In my case, the solution was very simple. Download using pip Django-nested-inline (without 's' at the end of the 'inline') and just change import. I didn't even have to change the code.
I'm working with django 1.7 and i have created this management command:
File structure:
app/
__init__.py
management/
__init__.py
commands/
__init__.py
modal_asign.py
Code:
from django.core.management.base import BaseCommand, CommandError
from webinar.models import Webinar
class Commands(BaseCommand):
help = 'Assign modal link to every webinar'
def handle(self):
latest_webinar = Webinar.objects.all().order_by('-webinar_date')[0]
for webinars in latest_webinar:
print "http://webinar.academiaa2.com/webinars/#displayModal" + webinars
and i'm getting this error when trying to test it with python manage.py modal_asign

Your class name is called Commands, whereas django expects it to be called Command. Hence the error.
Change
class Commands(BaseCommand):
to
class Command(BaseCommand):
I have following file structure:
/usr/share/pyshared/orca/scripts/toolkits/Gecko/script.py
In this file def getExtents is function that I have to access in following file i.e:
/usr/share/pyshared/orca/scripts/default.py
so I am trying to import function from script.py to the following file:
/usr/share/pyshared/orca/scripts/default.py
following line is added in /usr/share/pyshared/orca/scripts/default.py:
from orca.scripts.toolkits.Gecko.script import getExtents
But I get following errors:

I think you probably need
from orca.scripts import default
Also, as mentioned in the comments, check you've got the relevant __init__.py
edit: re-reading the stacktrace, looks like you've got a circular import too, you're trying to import orca.scripts.default in line 52 of "/usr/lib/pymodules/python2.7/orca/scripts/toolkits/Gecko/script.py"

What is wrong, or where could I find working examples?
This is a bug in the import. I fixed it in my fork; clone from there and then try it again.

This whole setup is already running on some server that I dont have access to, so it seems to be nothing wrong with django app or scripts...
Any help would be appreciated cause I am running out of ideas how to solve this problem...
I dont know your performance and scalability requirements, despite that a softswitch have realtime requirements to run rtp stream and signalling. So is not a good solution run django applications under mod_python. Furthermore that is not the same as python interpreter directly, somethings does not work. You can check the mod_python issues here:
mod_python issues
I would advice you to split your python solution in a client/server architecture. The script running under mod_python will make queries to your Django application. That way you will get rid of the complexity in Freeswitch side, get scalable, improve performance and most probably get everything working OK.
