Re: Dynamic menus using ul and li
A while back when I was trying to do a similar thing, someone mentioned using elementree to do this. I tried a bunch of other ways but in the end, elementree was the easiest way for me. If you'd like to see the template tag I created, you can see it here - http://www.satchmoproject.com/trac/browser/satchmo/trunk/satchmo/shop/templatetags/category_display.py Hopefully this will point you in the right direction. -Chris --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Dynamic menus using ul and li
What I need is a way to create nested menus using and with
the data coming from a model. I need to be able to get the entire
list:
Home
Some Category
Page
Even Deeper
Another Deeper Page
Another Page
Some Other Page
But also be able to pull a sub tree and tell it how deep to go:
Page
Another Page
Here is a sample of the model for the data...
class Page(models.Model):
title = models.CharField(maxlength=200)
slug = models.SlugField(prepopulate_from = ['name'])
parent = models.ForeignKey('self', blank=True, null=True)
content = models.TextField()
active = models.BooleanField(default = True)
show_in_menu = models.BooleanField(default = True)
I have spent the past week or so trying to figure this out and just
cant quite figure out how to do it... any help at all would be greatly
appreciated. And for the record, Django ROCKS!!
Eric

Re: Dynamic Menus...
Not really django related, but here goes: It depends on how you want to implement the form. 1. Using javascript and implementing a dynamic option list. You can find enough examples on dynamicdrive.com and other sites 2. Using Javascript an ajax you could hook into the onchange event of the first drop down list and fire off a xmlhttprequest to populate the second select list. 3. Or the static way: Select brand -> submit form -> display new form that lists the available models. mediumgrade wrote: > Don't know if this is a Django question or not, but here is the > situation: > > I am developing an application for a client who is a automobile broker. > He wants agents to submit requests for vehicles from the web.

I had to do this same exact thing - it's pretty easy to do with dojo. http://code.djangoproject.com/wiki/AJAX Josh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Dynamic Menus...
Using javascript would be the way to go. Though you have two options on how to know which car relates to which manufacturer. 1) AJAX: Query the server, which will return a list to be placed in the select field. 2) Hard coded JS: Hard code it into a JS array that will then be used to look up the fields and put it into the select box. If you go this route, you can put the JS into
Dynamic Menus...
Don't know if this is a Django question or not, but here is the situation: I am developing an application for a client who is a automobile broker. He wants agents to submit requests for vehicles from the web. The agent will be able to select the make/model of the vehicle. What I want is for the model menus to adjust dynamically depending on the make selected. For example, if the agent selects "Honda" I only the the models menu to show Civic, Accord, Element, ect. How can this be achieved? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
