Re: Q lookup with both OR and AND
Without looking into your problem in any real detail (sorry, late here), you could probably apply DeMorgan's Law and come up with a single predicate that you use throughout your query, using negation as appropriate. That may help you out. -- Kevin On 9/5/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > I'm having trouble piecing together a query for this model: > > class Ticket(models.Model): > ... > assigned_user = models.ForeignKey(User) > name = models.CharField(maxlength=255) > private = models.BooleanField(default=False) > > I'm trying to get all the tickets where the tickets are not private OR > the ticket is private and assigned to the current user. > > I'm foggy on where I use the comma, pipe, and ampersand characters to > get the query structured properly.

[newforms-admin]: Preload hook?
Hi, What's the best way to preload values into an admin form when using newforms-admin? I've managed to patch django to load form fields with default values from my model fields. But, this doesn't really allow for the arbitrary code based on the request that I would like. In particular, I'd like to be able to store the currently logged in user's id into a required field as the form loads. I can't seem to find a hook to do that. I have been able to accomplish what I wanted by overriding save_add() and loosening the required restriction. Obviously, by doing such, I also lose expresiveness and safety checking when using the model in any other context. Anyone have any ideas on how to go about hooking in at form render/load? -- Thanks, Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

(Some weird unique check errors.) I would have to agree with lenducha's synopsis. If the sequence is not updated, you will run into duplicate ID problems. The easiest thing to do right now is update all of your sequence curvals to be something large, where large is defined as being greater than count(*) for each table. -- Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I haven't looked into this deeply, but my guess is "no". Django's ORM is designed for the common use case. This typically means that no one is changing the DB behind you. If there is any work going on in this area, I'd be interested in hearing about it as well. -- Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

If you are using Eclipse Europa, you'll likely run into problems. It seems PyDev hasn't been fully flexed on this platform, nor with JDK 6. Fabio has been sensitive to these issues and has been addressing them fairly quickly. It seems each new release gets us a little bit closer. If you stick with Eclipse 3.2 and JDK 5, you'll likely be okay. -- Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

My guess is that using the session could achieve this for you. A "flash" persistence strategy would be better, but I'm unaware of one provided out of the box. -- Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

It's mostly just XML datagram forming and parsing, using standard HTTP libs for POSTing. I don't think you'll run into anything in django that will help you out or hold you back. I'd check out the Authorize.net XML guide. It's a pretty straightforward, albeit klunky, process. -- Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

While I can see the point you're trying to make, it seems like you're trying to dismiss his point as a technicality rather than address it at a technical level. The admin app is supported by the django devs, ships with django, and is a large component of the tutorials. For all intents and purposes (especially to someone just starting off), it is django. The original poster's problem was with "magic" in django, not just the core framework. FWIW, I don't necessarily agree with him.
