I just pulled it out of my github and tried to configure the application on my Ubuntu (I initially ran my application on a Mac at home).
I re-created the database and reconfigured settings.py - also updated the location of the templates, etc.
However, when I start the server "python manage.py runningerver", we get the error message:
ImportError: cannot import name Count
I imported Count into my views.py to use annotate ():
from django.shortcuts import render_to_response
from django.http import Http404, HttpResponse, HttpResponseRedirect
from django.db.models import Count
from mysite.blog.models import Blog
from mysite.blog.models import Comment
from mysite.blog.forms import CommentForm
def index(request):
blog_posts = Blog.objects.all().annotate(Count('comment')).order_by('-pub_date')[:5]
return render_to_response('blog/index.html',
{'blog_posts': blog_posts})
Why does not it work?
Also, if I delete the “Count Count” line, the error disappears and my application functions as usual.
Thanks, Wenbert
UPDATE:
my models.py looks like this:
from django.db import models
class Blog(models.Model):
author = models.CharField(max_length=200)
title = models.CharField(max_length=200)
content = models.TextField()
pub_date = models.DateTimeField('date published')
def __unicode__(self):
return self.content
def was_published_today(self):
return self.pub_date.date() == datetime.date.today()
class Comment(models.Model):
blog = models.ForeignKey(Blog)
author = models.CharField(max_length=200)
comment = models.TextField()
url = models.URLField()
pub_date = models.DateTimeField('date published')
def __unicode__(self):
return self.comment
UPDATE 2
My urls.py looks like this:
from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
(r'^admin/(.*)', admin.site.root),
(r'^blog/$','mysite.blog.views.index'),
(r'^display_meta/$','mysite.blog.views.display_meta'),
(r'^blog/post/(?P<blog_id>\d+)/$','mysite.blog.views.post'),
)
