hi all,
I've done some search, however, I guess I should ask for your helps
here:
I have the following models: (pseudo code)
class ArticleType:
name = ...
class Article:
title = ...
article_type = meta.ForeignKey(ArticleType)
class Game:
name = ...
articles = meta.ManyToMa

sorry for mistyped that, I tried this:

today while I'm using the comments module to implement something, I

1. in the models.py, the get_list_with_karma method should be updated

2. in the view

hi all,
I'm trying to use the generic view to slim down my code. here I
encountered a question:
I would like to use the generic object_list to list articles by
category, so, here is what I'm trying to do:
in urls.py -
article_list_dict = {
'queryset': Article.objects.all(),
}
urlpatterns
WoW! I'm currently using the 1st workaround :)
the 2nd one enlightens me a lot!
BiG thanks to Ivan :-D
btw, how about creating a more generic patch for django's generic view
methods? Since this is really a "generic" scenario - I usually need to
"get some object list by some condition" :)

FYI, we're using django's 0.95 trunk version to handle Chinese
contents, django works properly whether with sqlite3 or postgresql as
its db backend. pre-magic-removal django worked properly too.

hi Jaroslaw,
I guess you're trying to implement multipage forms.
here is the basic ideas:

step the user is doing
2. use the form manipulator.fields.append(forms.) to
dynamically create form's layout base on 'step'
3. while pr

hi Malcolm,
thank you very much for your quick reply!
I knew I need to build my custom SQL, my friend (who is a db master :)
just came back and suggests me to do this:
select object_id, count(*) from tagging_object_tag where tag_id in (15,
16) group by object_id having count(*)=2;
pretty cool
o, the count(*) is unnecessary,
select object_id from tagging_object_tag where tag_id in (15,
16) group by object_id having count(*)=2;
