Hi, I am new to both Django and Python and yet I'm developing a site for myself. I have some programming skills in REXX, Pascal and Bash and that helps a little.
I need to do one of the simplest things, yet I hit a roadblock. I lost literally a week searching every little page for solution to my problem. It appears quite obvious on the first look but my brain is clogged right now because I read a quick introduction to Python and nearly whole djangobook.com trying to understand as much as i can. This was too much. Anyway, back to the subject: I need to display two Panels at *every* subpage - that's why I thought about using template tags. Each Panel would hold Categories sorted by "position" field (and "-date_mod" as fallback). Each Category could hold elements such as Link (with "url" and "name" fields) and Page (semi-static, with "content", "visible" and "date_pub"). Link and Page both have "category" field which is a ForeignKey(Category), "position" field which should determine their position in Category (again "- date_mod" as fallback sort) and a "date_mod" field. If you have better idea how to achieve this simple goal, please share it. All I need is to write a subpage and assign it to a category, and link to that subpage should appear in that category. And if I want to put a link to external page in the same category it should appear there just like that. I've put up a static demo of what I have in mind: http://dominik.kozaczko.info/django/ I have stripped-down model here: http://pastebin.com/m3f5cf035 Plus here is template_tags definition and the test template: http://pastebin.com/d167aa968 The problem is - when I eneter all queries in shell, they behave perfectly. But this does not work in real world. I tried debugging with print statements - context is returned perfectly to the template. Yet the for loop can't iterate through 'list_groups' and an error occurs at line 53 (second pastebin), where the "for" loop begins. It returns error "Group matching query does not exist." and the traceback is like this: Traceback: File "/usr/lib/python2.4/site-packages/django/template/debug.py" in render_node 71. result = node.render(context) File "/usr/lib/python2.4/site-packages/django/template/defaulttags.py" in render 149. nodelist.append(node.render(context)) File "/home/dominik/stuff/projekty/django/test/../test/szablony/ templatetags/szabtags.py" in render 87. objects = Group.objects.get(id=self.groupid) File "/usr/lib/python2.4/site-packages/django/db/models/manager.py" in get 82. return self.get_query_set().get(*args, **kwargs) File "/usr/lib/python2.4/site-packages/django/db/models/query.py" in get 196. raise self.model.DoesNotExist("%s matching query does not exist." Exception Type: DoesNotExist at /test/ Exception Value: Group matching query does not exist. I have no idea what is wrong :( Again, if you have better idea how to achieve this simple goal, please please please share it. I use Django-SVN and Python 2.4 on Linux Best wishes, Dominik Kozaczko --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
