django channels in the shell

[chris rose]

I'm trying to implement a custom management command into my app.

its purpose would be to check the database for a poll which fits time 
parameters and update clients via channels.

I want to get a list of the clients in a group, then decide whether or not 
to send them new information based on their session data

I have been exploring this in the shell and im wondering why my client 
doesn't receive a message when i use the following code:

from django.conf import settings
from django.utils.module_loading import import_string

config = getattr(settings, "CHANNEL_LAYERS", {})
backend_class = import_string(config['default']['BACKEND'])
channel_layer = backend_class(config['default'].get("CONFIG", {}))

channel = channel_layer.group_channels('poll')[0]
channel_layer.send(channel, {"text": "hello world!"})

slug = SlugField(.)

class MyModel(modesl.Model):
post = models.CharField()
slug = models.SlugField(.)
categories = models.ManyToMany(Category)

   def get_absolute_url(self):
   return "/%s/%s-%s/" % (self.categories.slug, self.id, self.slug)

  #error 'ManyRelatedManager' object has no attribute 'slug'
  in self.categories.slug


i would like this url in my page
127.0.0.1:8000/category-slug/id-slug-post

example
http://mydomain.com/food-green/120-one-hundry-food-green
  domain.com / category slug   / pk - (dash) post slug

https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.ManyToManyField

https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.ManyToManyField.through

The "through" table doesn't need a coded Django model if it is only used 
to relate the two different tables in the m2m relationship. However, if 
you want to include other data - such as a slug - then you need to code 
it explicitly.


The "through" table will already exist in your database so choose the 
same name for the model as you see there. It will only have two foreign 
key fields, one to each of the related tables after which it is named.


Once you have a model with the two FKs and your slug, 
makemigrations/migrate will adjust it to include the slug.
