tutorial part 4: ImportError

[steph]

Hi group,

I'm new - just worked thgough the tutorial. In part 4 about the use of
generic views I've got a problem - I can't import ListView and
DetailView:

>>> from django.views.generic import DetailView
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name DetailView
>>> from django.views.generic import ListView
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name ListView

I'm on the newest version of django: first tried with version 1.2.3,
then I upgraded to 1.3 alpha - same problem.

Any clues?

thanks,
stephan

ps: other than that it's a great tutorial!

Steph,   those instructions are incorrect try from djanog.views.generic import list_view, list_detail   Michael --- On Tue, 11/23/10, steph <step...@yahoo.de> wrote:

Firstly friend,

1.3 alpha has been released as a testing package. It isnt the most
stable version and not meant for production, I would revert back to
1.2 unless your plan is to help the django team with bug fixes.


Also, you are reading the wrong tutorial for your version, that is
why you are getting that error.

http://docs.djangoproject.com/en/1.2/intro/tutorial04/

Here is the one you want, I can see why that would be a bit confusing
to you.

Are you sure you've upgraded correctly? It won't work at all if you
have anything less than 1.3 alpha - the tutorial you're using is for
the development version only (there's a big link at the top of the
page for the one that works in previous versions), and generic views
are one big element that has changed since 1.2. How did you install
1.3?

>>> import django.views.generic
>>> dir (django.views.generic)
['GenericViewError', '__builtins__', '__doc__', '__file__',
'__name__', '__package__', '__path__', 'list_detail']

ok, I can see list_detail now :-) ... but the other?

maybe a problem with my installation ...

Ok, sorry - didn't get it about the tutorial versions ... it didn't
appear to me that 1.2 tutorial was about version 1.2.3. - silly me ;-)

How I did install 1.3: download ... setup.py. Just as in INSALL-file.

As mentioned before,

If you are using Django 1.2 you dont need to import list_view or
detail_view just 'from django.conf.urls.defaults import *'

As the tutorial documentation for 1.2 http://docs.djangoproject.com/en/1.2/intro/tutorial04/
instructs:

from django.conf.urls.defaults import *
from polls.models import Poll

info_dict = {
'queryset': Poll.objects.all(),
}

urlpatterns = patterns('',
(r'^$', 'django.views.generic.list_detail.object_list',
info_dict),
(r'^(?P<object_id>\d+)/$',
'django.views.generic.list_detail.object_detail', info_dict),
url(r'^(?P<object_id>\d+)/results/$',
'django.views.generic.list_detail.object_detail', dict(info_dict,
template_name='polls/results.html'), 'poll_results'),
(r'^(?P<poll_id>\d+)/vote/$', 'polls.views.vote'),
)

Hi group,

I've noticed a few things in the tutorial documentation for 1.2 on page http://docs.djangoproject.com/en/1.2/intro/tutorial04/ under the section "Use generic views: Less code is better":

1.  It instructs the user to rename both the detail.html and list.html pages to poll_*.html, but it doesn't say to rename the results.html file to poll_results.html, which in turn in polls/urls.py, the template_name='polls/results.html' seems to need to be changed to template_name='polls/poll_results.html' to be properly used by the generic views. 

2. Also, in polls/views.py, in the vote model, poll_id needs to be changed to object_id in the signature, although the instructions only say to change these references in the templates and in the render_to_response call (it may have been implied to change the vote model signature when the author says that 'The object_detail() generic view expects the ID value captured from the URL to be called "object_id", so we've changed poll_id to object_id for the generic views.', - if this is the case then ignore this one :) 

3. Also in polls/urls.py in the import line "from django.conf.urls.defaults import *" seems to be an unused import

Can someone check to make sure that I am correct on this list?  Maybe I am off-base on some of this.  Thank you!

**some corrections from my previous post
By "model" I mean "view" and in #1, index.html gets changed to poll_list.html
Sorry!
