Django view doesn't display model value - Django 1.5 - django

Question

I created a very simple example code using Django, but cannot get model value to be displayed on my page:
----------------------------- home/models.py
from django.db import models
class Home(models.Model):
msg = models.CharField(max_length=100)
#classmethod
def create(cls, msg):
home = cls(msg=msg)
# do something with the book
return home
home = Home.create("Hello World!")
------------------------------------home/views.py
from django.views.generic import TemplateView
from project.models import Home
class IndexView(TemplateView):
model = Home
template_name = 'home/index.html'
------------------------------------------ templates/home/index.html
{{ home.msg }}
this is a test page. I am expecting to see this....
------------------------------------------- urls.py
from django.conf.urls.defaults import patterns, include, url
from django.contrib import admin
from django.views.generic import TemplateView
admin.autodiscover()
urlpatterns = patterns('',
# Home pagetentacl.urls
url(r'^$', TemplateView.as_view(template_name='home/index.html')),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
url(r'^admin/', include(admin.site.urls)),
)
-------------------------------------- result page on browser:
this is a test page. I am expecting to see this....
I don't want to have DB access for my example. I want my model returns "hello world" string. home.msg on index.html doesn't return anything. What is missing here?

Answer 1

You're not giving the template an instance of Home. You need to create one and pass it to the template as a Context, in the form {'msg': msg}.
EDIT: Adding some code
First of all, you should create your instance of home in your view. I've never used TemplateViews, so I'm going to use a regular view method instead.
def IndexView(request):
home=Home.create("Hello World!")
return render(request, 'index.html', {'home': home},)

Answer 2

As #Daniel rightly points out, you're not giving your template an instance of Home to work with.
If you want to use class-based views, subclass TemplateView and override get_context_data():
class IndexView(TemplateView):
template_name = "home/index.html"
def get_context_data(self, **kwargs):
context = super(HomePageView, self).get_context_data(**kwargs)
context["home"] = Home.create("Hello World!")
return context
And make sure your urls.py is using IndexView.as_view() - your version above is just referencing the generic TemplateView.
The fact that you added a model field to your subclass of TemplateView makes me think you're confusing it with DetailView. See the documentation for the difference.
