Re: Understanding sessions
Looking at the django-cart open source code:
cart = request.session.get('cart', None) or Cart()
Does the new cart object that recently got created be put back into
request.session['cart'].
I was thinking of improving the code located in
http://code.google.com/p/django-cart/source/browse/trunk/django-cart/shop/views.py
by adding a get_cart()
def get_cart(request):
cart = request.session['cart']
if cart == None
cart = Cart()
cart.save()
request.session['cart'] = cart
return cart
Is there a cleaner way of doing this.
Thanks in advance.

Understanding sessions
What is happening here:
fav_color = request.session.get('fav_color', 'red')
Is it trying to retrieve 'fav_color' from the session. If it doesn't
exist, does it put it in the session and assign the value 'red' for
it.

using django-gcal, how do i defined the "instance" parameter

use vObject for event calender application?
Has anybody had any experience using vObject (http:// vobject.skyhouseconsulting.com/). I want to try to create an event calendar application in django and all blogs/website suggest that I use this as part of the backend. Just want to make sure that I am going down the correct path. I haven't seen a prepackage event app yet, does one exist. If not, is this the best way to go. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Hi Steve, the cycle tag fixed the issue.
Thanks.

strategy for deploying to production server
Just trying to get a feel for what other developers are doing when deploying to a production server. There are some differences between my development machine and production server such as the location of my media files, the database settings, and if I want to enable caching or not. Right now my option is to comment out some of the code and uncomment the other values. This is time consuming and error proned. How do you deal with this issue of working in your development machine and then having to deploy the same code into your production server. Some files I modify are the settings.py/url.py/views.py. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: using forloop variable to get the provide special tags for the 4th element.
Thank you. I'll test this out. I also found the "cycle" tag which
looks very promising.

using forloop variable to get the provide special tags for the 4th element.
In the django template where I am using a for loop, I have to use a
special tag (div class="yui-u first" instead of div class="yui") for
every forth item. Im trying to create a table with three columns. I
can access the first loop but how do I do it for every third.

working with yaml fixtures
I'm trying to initialize my database using yaml fixtures. I've created a yaml fixtures directory (src/fixtures). Within the yaml fixtures directory, I created a yaml fixtures file title websites.yaml. I first had error saying that: neptune:$ python manage.py loaddata fixtures/websites.yml Problem installing fixture 'fixtures/websites': yml is not a known serialization format. I think the solution to that problem was to install pyyaml package. I have done that. Now when I try to invoke the command "python manage.py loaddata fixtures/websites" inside my src directory, it gives me no error message but nothing is added into my sqlite database. --- sample of my yaml file -- - model: src.website fields: title: Our Awesome Planet url: http://www.ourawesomeplanet.com feed: http://feeds.feedburner.com/ourawesomeplanet - model: src.website fields: title: The Unlawyer url: http://www.unlawyer.net feed: http://www.unlawyer.net/?feed=rss --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

how do i do background tasks
i'm creating an application that will read rss feeds. i'm using the universal feed parser library. i have a feed model (has the url to the feed) and an entry model (for each individual entry). Is there a method in the model that I have to overwrite that will allow me to retrieve rss entries in the background and save it into the model. that way the rss feeds from a particular blog are read every hour and stored into the database for viewing. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
