Description (last modified by Alex)

Got the following error:

ValueError at /text/5/

need more than 1 value to unpack

Request Method: 	GET
Request URL: 	http://localhost:8000/text/5/
Exception Type: 	ValueError
Exception Value: 	

need more than 1 value to unpack

Exception Location: 	/var/lib/python-support/python2.5/django/db/models/sql/query.py in add_filter, line 1101
Python Executable: 	/usr/bin/python

Python Path: 	['/media/Daten/Projects/Webproj/evankproj', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/Numeric', '/usr/lib/python2.5/site-packages/PIL', '/usr/lib/python2.5/site-packages/gst-0.10', '/var/lib/python-support/python2.5', '/usr/lib/python2.5/site-packages/gtk-2.0', '/var/lib/python-support/python2.5/gtk-2.0', '/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode']

With a Model

  6 class Text(models.Model):
  7     text = models.CharField(max_length=(10 ** 5))
  8     date = models.DateTimeField()

With a view

  7 def view_text(request, text_id):
  8     text = get_object_or_404(Text, text_id)
  9     return render_to_response(u"text.html", {u"text": text})

The Following is the output of the development server:

[11/Mar/2009 16:30:39] "GET /text/5 HTTP/1.1" 301 0
[11/Mar/2009 16:30:39] "GET /text/5/ HTTP/1.1" 500 71938

text/5/ works as in the Django Tutorial with polls/\d+ for a poll_id.

I didn't find anything relevant in the tickets on a search for the traceback message (tuple unpacking failing).

  • Resolution set to invalid
  • Status changed from new to closed

In this example what is text_id? It looks to me that what you meant to do is get_object_or_404(Text, id=text_id) and thus I'm marking as invalid.

Yes, meant that. Just didn't see it. But, well, the Traceback looks very confusing and deeply in the hierarchie. Maybe improvable?
