Question:
I want to use an app to create a menu that is easy to edit with the admin interface. Something like this:
class Menu_item name = models.CharField() item_url = models.URLField()
My template looks something like this:
{% extends base.html %}
div ID="nav"
{{ foo.navbar.? }}
/div
div ID="Content"
{% block content %}{% endblock %}
/div
I want div#nav to contain a ul based upon the above model but just can't figure out how to accomplish this. It seems like an object_list generic view would be great but, the URL accesses the view for the model that populates div#content. Does anyone have any suggestions? Is there a way to access a generic view without a URL?
Thank you.
Solution:1
First, in you view, get data from db:
def index(request): navbar = Menu_item.objects.all() return render_to_response( 'you_template.html', { 'navbar': navbar }, context_instance = RequestContext (request ) )
And in template:
<div id="nav"> <ul> {% for i in navbar %} <li><a href="{{ i.item_url }}">{{ i.name }}</a></li> {% endfor %} </ul> </div>
Solution:2
I have discovered a solution. Inclusion Tags.
What I did was create an inclusion tag, which amounts to a simple custom template tag (django provides a shortcut for you!).
Here is what I did:
mysite/ navbar/ templatetags/ __ init__.py (without the space befire init) get_navbar.py
from django.db import models class Menu_choice(models.Model): name = models.CharField(max_length=30) def __unicode__(self): return self.name class Menu_item(models.Model): name = models.CharField(max_length=20) navbar = models.ForeignKey(Menu_choice) item_url = models.CharField(max_length=200) item_desc = models.CharField(max_length=30) def __unicode__(self): return self.name
This allows me to create a Menu_choice object in the admin interface for each layer of navigation (primary, secondary, etc)
from navbar.models import Menu_choice, Menu_item from django import template register = template.Library() @register.inclusion_tag('navbar/navbar.html') def get_navbar(navBar): navbar = Menu_item.objects.filter(navbar__name=navBar) return { "navbar": navbar }
(Note navBar as opposed to navbar)
<ul>
{% for menu_item in navbar %} <li><a href="{{ menu_item.item_url }}">{{ menu_item.name }}</a></li> {% endfor %} </ul>
{% load get_navbar %}
And where I want primary navigation:
{% get_navbar "primary" %}
Note: the quotes around the string you are sending to your inclusion tag are important. I spent a ridiculously lengthy bit of time trying to make it work before I figured that out.
Also a big thank you to dikamilo for the help.
