Managing hierarchial data, with Django
Hey everybody, Django is a wonderful tool. It gives you so much freedom of thought. Still I got a problem that I can't figure out up to now. What is the best way for Django to manage hierarchial data? It is totally possible to add a self-referential foreign-key to every model. I also was pointed to django-mptt (http://code.google.com/p/django- mptt/) by some users referring hierarchial data. Problem is: How does the automated admin (after all djangos killer- feature) handle these hierarchial models? I'm searching for a solution for users to easily manage a tree of pages, like in Wordpress, but I see now way that the automated admin would display such a tree. I'd be glad for any advise that you guys could give me! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Problems using mptt
Hey everybody,
I'm trying to added mptt to my django project for managing a simple
page-tree. It doesn't seem to work, as it is supposed too.
My model looks like this:
from django.db import models
import mptt
class Page(models.Model):
title = models.CharField(maxlength=200)
body = models.TextField()
parent = models.ForeignKey('self', null=True, blank=True,
related_name='pages')
class Meta:
ordering = ['parent']
class Admin:
pass
def __str__(self):
indent = ""
for i in range(self.lvl()):
indent += "-"
return '%s %s' % (indent,self.title)
def level(self):
if(self.parent == None):
return 0
else:
return self.parent.lvl() + 1;
But even in this stage, without the mptt.register, my development
server gives me a
> Validating models...
> djangotree.content: cannot import name ugettext
> 1 error found.
I guess that is related to the mptt, but I have no idea, what might be
causing this.
Can somebody help out?

Accessing a ManyRelatedManager by introspection for JSON/AJAX ?
Hey everybody,
I'm currently trying to build an AJAX-JSON-processor with Django,
which receives a JSON-encoded request and then writes those values to
the database.
Here is what I basically looks like:
{"class":"pages.page",
"id":"1",
"show_more_on_topic":"0",
"show_archive":"1",
"title":"Homepage lala",
"show_global_teasers":"1",
"show_infos":"0",
"show_keywords":"1",
"show_next_dates":"0",
"content":[{"class":"pages.leadcontainer",
"id":"15",
"type":"standard",
"sortKey":"1",
"leads":[{"class":"pages.lead",
"id":"2",
"headline":"value",
"subline":"value",
"anreisser-text":"Lorem ipsum dolor sit amet"},
{"class":"pages.lead ..
I already got it managed to create and save simple Django-objects and
setting their respective attributes. Now I would like to process the
collections that come inside of some of those JSON-arrays. I accessed
the simple attributes through the __dict__-array. Now I need a way to
access those collections and add/delete/recreate them.
How would I do that?
BTW: I know that there is a JSON-(de)serializer. But since in this
case Django shall be the backend of a more sophisticated AJAX-
interaction, I need a little more functionality than just saving and
serializing.

Re: Accessing a ManyRelatedManager by introspection for JSON/AJAX ?
This is a sad self-reply. I got around this problem by using eval() and accessing the collection that way. Be careful with security though! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Overwriting the save-function in automatic admin?
Hey guys, I've written my blog in Django and am quite happy with it. Yesterday I implement trackbacks, so that Django kann accept them for posts. Next goal is to be able to send trackbacks. Since I put all my stuff into my blog through the automatic admin, my question is: Is there a way to overwrite the save-function for certain Models? Here is what I'd like to do: Add a "Trackbacks"-field to my "Post"-Model and when somebody pushes "Save" in the Admin, it starts pinging the trackbacks and then save the object afterwards. Or is there a better way to do that? Thx in advance. Tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
