There may be individual reusable apps that provide what you need, but Django itself does not come with a tree view, nor does it pick a particular JavaScript library to integrate. This means you have all the flexibility you may need to build whatever components your application requires. This also means you often have the burden of developing the front-end by yourself. In my case, I have had good results incorporating the jQuery Dynatree plugin into my application. However, I did the integration entirely myself. If you only have "a day or more" to invest on building the front-end, and you are not comfortable building HTML and wiring up JavaScript, but you *are* comfortable with PHP, then PHP may be the better choice for your needs. On the other hand, if you continue to build web applications, you will need to develop a certain expertise with HTML, CSS and JavaScript, in addition to your server-side framework and its language, so you may want to put the time in to learn the tools now.

Tree view me

I'd suggest taking a look at django-mptt. It solves this problem (and
some more) neatly:

formatting queryset for tree view
Hi all,
Here I have a model called Product. It has a self relationship as shown
below.
class Product(models.Model):
name = models.CharField(max_length = 200, blank = True)
main_product = models.ForeignKey('self', verbose_name = "Subproduct
of", help_text = "sl.no. of the containing component", blank = True, null =
True)
sl_no = models.CharField(max_length = 200, verbose_name = "Serial
No.", blank = True)
make_model = models.CharField(max_length = 200, verbose_name = "Make &
Model", blank = True)
I have to show these products in a tree view in template. Here product-1 can
have a subproduct prouduct-2 and product-2 can have a subproduct prouduct-3
and so on. Can anyone suggest an efficent way to repersent this as a
tree(means how the queryset be formatted before rendering to
template).
Thank in advance.

Displaying a Tree view in template using django-mptt
Hello Dear all,
First let me say that i'm very new in term of web based developpemnt
(the HTML/CSS Part). i've always worked on backend logic (in java,
python, etc) never on the end user interface directly.
This said, i'm trying to use the django-mptt to install a simple
hierarchy in my first django app.
And I'm blocked at the view template / level
(ie rendering something for the end user)
At the model level, the integration is successful.
i've registered my Item model in mptt.
My Item has a 'parent' field that is used by mptt to discover parent/
child relation ship.
So i can create some Item hierarchy in a breezeAnd i can use it on
the python command line.
But i can't figure my self how to integrate this in a template.
What i'm looking for is a way to render the whole item Tree.
Each item would have it's own line with it's title
Each item would be a little more on the right side depending on the
depth in the hiearchy
Each item would have a link on the right to edit himself
Each item would have a link on the right to move himself
So i guess i should use the mptt template tag
{% full_tree_for_model myApp.Item as OneItem %}
But then, how do i display for each OneItem
1) OneItem deppth in the tree
2) OneItem title
3) OneItem pk id (to generate the right link)

It's still not semantic (uses presentation style instead of nested
s). It's looking like if I really want a true list view I need to
build a custom tag. Right now I think I'm just going to spread the tree
out across the URL space.

Re: Tree View
See these cookbook recipes for ideas: http://code.djangoproject.com/wiki/CookBookCategoryDataModel http://code.djangoproject.com/wiki/ModifiedPreorderTreeTraversal I use a custon template tag to make a tree-like navigation menu by turning the tree into a straight list with depth information on each item. My tree structure comes from Flatpages URLs though and not a recursive model. Anyway I thought it's wise to do all the complex stuff (be it recursion or otherwise) in Python in the view and have the template deal with just a straight list.
