Hi Ned,
I figured as much, but since without the 'try' made no difference, I
thought I'd give it a whirl.... here is the source.
'lukenslanguages' is the project directory.
#lukenslanguages/weblog/models.py
from django.db import models
class Category(models.Model):
name = models.CharField(maxlength=20)
url = models.SlugField(prepopulate_from=("name",))
def __str__(self):
return self.name
class Admin:
pass
class Entry(models.Model):
title = models.CharField(maxlength=100)
url = models.SlugField(prepopulate_from=("title",))
category = models.ForeignKey(Category)
body = models.TextField()
date = models.DateField()
def __str__(self):
return self.title
class Admin:
pass
#lukenslanguages/urls.py
from django.conf.urls.defaults import *
from lukenslanguages import views
urlpatterns = patterns('',
(r'^admin/', include('django.contrib.admin.urls')),
(r'^site_media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': 'C:/django-0.96.1/lukenslanguages/templates/'}),
(r'(^[a-z-]+)/$', views.entry_list),
)
#lukenslanguages/views.py
from django.shortcuts import render_to_response
from weblog.models import Category, Entry
from django.template import loader, RequestContext
from context_processors import menu_list
def entry_list(request, category):
c = Category.objects.get(url=category)
entries = c.entry_set.all()
return render_to_response('weblog/blogentry_list.html',
{'entries': entries, 'category':
c.name, 'title': c.name},
context_instance=RequestContext(request, processors=[menu_list]))
#lukenslanguages/context_processors.py
from weblog.models import Category
def menu_list(request):
"A context processor that serves the categories for use as menu
items"
return {
'categories': Category.objects.all()
}
#lukenslanguages/weblog/templatetags/blog_extras.py
from django.template import Library
from lukenslanguages.weblog.models import Entry
register = Library()
@register.filter
def category_url(entry_id):
e = Entry.objects.get(id=entry_id)
return e.category.url
I think that this is all of the pertinent code. If you would like to
see anything else, please let me know.
Thank you,
Jonathan
