/ feed /处的ValueError-以10为底的int（）的无效文字

Question

I need to display a feed for a user for a set of actions. I'm using Django Activity Stream for this. I just started to test the application but I can't seem to display the users feed.

As per the Action Stream documentation I'm using the actor_stream function as follows

from actstream.models import actor_stream

def user_feed(request):
    print actor_stream(request.user)

This gives me a error

ValueError at /feed/
invalid literal for int() with base 10: '<property object at 0x2a6a520>'

Here is the traceback

print type(actor_stream(request.user)) evaluates to <class 'actstream.gfk.GFKQuerySet'>

I even tried typcasting it as a list and then printing it but it still throws the same error. How should I be accessing the actor stream in my view?

EDIT - I'm using a Custom User Model if that makes any difference.

What if you do instead :

from actstream.models import actor_stream

def user_feed(request):
    print actor_stream(request.user.pk) # added .pk here

As you can see at the end of the stacktrace ( return int(value) ), django try to convert request.user to an integer. I think it fails because you use a custom User model, and have not any __int__ method defined in it. Try to had this method in your User model :

class UserModel(models.Model):

# your logic here

def __int__(self):
    return self.pk
