Hey all,
I am recently trying out the examples from the link
http://www.djangobook.com/en/1.0/chapter03/, where the current time
have to be displayed and then modify and display the offset. I was
able to display the time without any issue, but with the offset part,
i get the error
TypeError at /time/plus/1
'tuple' object is not callable
Exception location: mysite\urls.py in <module>, line 6
My urls.py is as follows.
from django.conf.urls.defaults import *
from mysite.views import current_datetime, hours_ahead
urlpatterns = patterns('',
(r'^time/$', current_datetime)
(r'^time/plus/(\d{1,2})/$', hours_ahead),
)
my views.py is as follows.
from django.shortcuts import render_to_response
import datetime
def current_datetime(request):
now = datetime.datetime.now()
return render_to_response('temp.html', {'current_date': now})
def hours_ahead(request, offset):
offset = int(offset)
dt = datetime.datetime.now() + datetime.timedelta(hours=offset)
return render_to_response('temp.html', {'hour_offset': offset},
{'next_time': dt })
my temp.html is as follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html lang="en">
<head>
<title>Future time</title>
</head>
<body>
<h1>My helpful timestamp site</h1>
<p>In {{ hour_offset }} hour(s), it will be {{ next_time }}.</p>
<hr>
<p>Thanks for visiting my site.</p>
</body>
</html>
pls help. I am really lost :(

Missing comma after the first pattern. Thus you have (r'^time/$',

current_datetime)(...), which is syntax for calling the first tuple.
That causes the error.

line, just one:
{'hour_offset': offset, 'next_time': dt }

module called postgresql. Or if there is, it will not be usable with
Django. If you are using Django, you should set the DATABASES in
settings.py correctly, and just use "from django.db import connection"
and use that. See the documentation for how to do this.
I understand you are a beginner and things can seem cryptic at first.
However, I must encourage you to solve these issues on your own as
much as possible. For example the first problem you had was pretty
well pointed out to you by Python's exception message:
TypeError at /time/plus/1
'tuple' object is not callable
Exception location: mysite\urls.py in <module>, line 6
- Anssi'tuple' object is not callable
Exception location: mysite\urls.py in <module>, line 6
