"select for update" with models
Hi, I'm new to Django -- looking to write a credit card transaction module and I need the ability to perform a "SELECT FOR UPDATE" (mysql) so that an order does not get processed by two different threads. I see an open ticket for this here: http://code.djangoproject.com/ticket/2705 Has anyone successfully used this code in a production environment? Any workarounds that people can think of?

virtual currency / check-in apps
Can anyone recommend any apps/tools for implementing either virtual currency or "check-ins" in Django?

Deleting sessions without Request object
Is it possible to log out a user manually? The desired result is that after I do this, the user will be forced to log in again. I will not have an active Request object (ie, this will be done from the admin app or a management command, not a view). Can I simply add the Session table to the admin app and manually delete a user's entry? Thanks, Greg -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Temporary group membership tally - Any clever way to do it?
Why not have a "user.membership_exp_date" field. If a user signs up on day 0, the membership_exp_date could be set to now() + 5 days. This will let you query the results in real-time. No cron job needed.

Re: What is a good source code control software?
This doesn't really have much to do with Django, but here is my 2 cents: If you have no experience with version control software, I'd recommend that you start with subversion. There are more advanced tools (git and mercurial being the favorites right now), but there is a steep learning curve if you are a beginner. I chose git for my company after using subversion for years, and I had to learn its nuances over time (ie, it was really frustrating at times). For a while you'll find yourself unable to do basic things (adding files, merging changes, making commits) when you encounter problems. If the danger of this sounds worse to you than the advanced features/benefits of a distributed VCS, go with subversion. If your team is highly tech savvy (perhaps they already know git/mercurial), then those may be better options, but it doesn't sound like that is the case (or they probably would have recommended one to you). I recommend finding an external host. They are cheap and you won't have to worry about hardware/backups/administration yourself.

Re: scaling my site
You will need to find/hire a sysadmin if you can't do this yourself. We looked into Amazon for our purposes and found their interface kludgy and their documentation confusing rather than helpful. Also, I kept a server running idle on Amazon for a month and it was more expensive than slicehost ($20/month), which we ultimately chose. In any event, it sounds like you should find a sysadmin to help you with these decisions/tasks.

Re: Displaying images
Are your settings properly set up? Can you confirm that you are able to
print settings.MEDIA_URL in your view? MEDIA_URL defaults to the empty
string, so that seems like the problem. Then, pass in the request context
as I described previously.
>From http://docs.djangoproject.com/en/dev/ref/templates/api/
If TEMPLATE_CONTEXT_PROCESSORS contains this processor, every RequestContext
will contain a variable MEDIA_URL, providing the value of the MEDIA_URL
setting.

Using Django to white-label sites for multiple clients
I'm looking to "white label" a site built using Django.
For those unfamiliar with white-labeling, we would like my site (call it
"Amazing Site") to be able to be customized by sponsors A and B. Customer A
provides us with their header, footer, css, and we can do *basic*
re-branding, in order to present the site as "A Amazing Site" (or B's
Amazing Site).
I have considered rolling my own by changing the base template. So instead
of
{% extends "base.html" %}
I would pass in a variable from the view:
{% extends site-base-template %}
Have others tried this? Are there existing strategies? Perhaps a django app
that takes care of this?
Thanks,
Greg
