'str' object is not callable in base.py

Hi all,

Stumped on this one:


Traceback:

urls.py:
...
url(r'^timetable/(?P<slug>[-\w]+)/$', 'timetable_view'),
...

views.py:
@login_required
def timetable_view(request, slug):
timetable = get_object_or_404(slug=slug)
sessions = timetable.sessions.all()
return render_to_response('tafe/timetable_detail.html',{'timetable':timetable,'sessions':sessions})

models.py:

class Session(models.Model):
...
timetable = models.ForeignKey(Timetable, related_name='sessions')
...

What am I doing wrong?

cheers

From this post i can see this line beeing wrong . 

timetable = get_object_or_404(slug=slug) 

You also need to give object as one of the parameters for get_object_or_404 shortcut: like this :

My best guess is that, for whatever reason, 'timetable_view' in your url conf
has not been converted into the view function. Try actually importing the
view in urls.py and putting it as the target of the pattern *without*
the quotes.
If this works, then figuring out whether you needed 'app_name.timetable_view'
or some such is where to look. If it still doesn't work, you may get additional
insights (can you actually import views.py, or does it have a syntax
error, etc.).

Thankyou for pointing this out - it was indeed wrong and has now been fixed. Unfortunately, it didn't solve the problem.

cheers

Yes, this was the answer - thanks Bill.

I tried tafe.timetable_view and it didn't work, so I tried  

from tafe.views import timetable_view

and it did...

then I realised I needed

'tafe.views..timetable_view'

 as the pattern target.

Thanks for your help
