Possible typo in Tutorial page #4

[Dustin Farris]

Following the introductory tutorial:

​http://docs.djangoproject.com/en/dev/intro/tutorial04/#intro-tutorial04

The example showing the view() function calls the reverse() function passing a tuple as the "args" argument. This seemed to generate the following error from Django:

"reverse() argument after * must be a sequence, not long"

Fiddling with the code, I realized that reverse() seemed to expect a list for "args", not a tuple. Changing the code to ... , args=[p.id])) cleared the error.

Sounds like you did not include the trailing comma in the tuple. Note the doc has, for example:

return HttpResponseRedirect(reverse('poll_results', args=(p.id,)))

The comma after p.id is required for the single-element tuple to be recognized by Python as a tuple, and thus a sequence. This is a standard Python gotcha, see: ​http://wiki.python.org/moin/TupleSyntax.

(If the trailing comma is missing some place on that page, please point it out exactly; I'm not seeing any missing commas for the args to reverse.)
