You pass them as a Context object to the render() method of the
template - which is what your code is doing.  IOW : the problem is
probably elsewhere.

I assume that
1/ you are running the builtin dev server with the DEBUG flag set to
True in your settings,
2/ you do have some posts in your database,
3/ you already made sure your code was using the right template (like
by editing something in your template and reloading the url to check
if you see the edit).

Retrieve datas from database

[by-neron]

hi there,

i'm new with Django.

What i want is that retrieve some datas from db. First of all,

i have a project called mysite and project has an application called
blog. Project file has template/ directory which includes html files
of site.Additionally, blog application has a model like that

class Post(models.Model):
title = models.CharField(max_length=100)
body = models.TextField()
created = models.DateTimeField()
tags = TaggableManager()


def __unicode__(self):
 return self.title
in this app i have also view.py

from django.template import Context, loader
from blog.models import Post
from django.http import HttpResponse

def index(request):
latestPosts = Post.objects.all().order_by('-created')[:5]
t = loader.get_template('/mysite/templates/index.html')
c = Context({
'latestPosts': latestPosts,
})
return HttpResponse(t.render(c))
however,

in mysite/template/index.html

 {% for post in latestPosts %}
 {{ post.id }}
{% endfor %}
prints nothing because it could not send data here. How can i send it ?
