Self Join

I'm trying, without a great deal of success, to perform a simple self join using the django orm. I'm pretty sure the F() function is not the answer. I believe this only allows you to compare two field within the same model instance, not to compare fields within 2 instances of the same model. I w

Re: Self Join

Django ORM

I have a statement--- Container.objects.get( pk=container_id ).delete() This seemingly trivial operation hammers the db with 581 queries!! The reason being that the django orm has decided that it will enforce referential integrity as a default behavior. As you could imagine, thi

Re: Django ORM

Russ and Javier, Just to be clear... the reason for my initial note was due to my already having a work queue which performs cleanup and maintains data integrity. It is precisely due to this that I'm surprised the ORM has cascading deletes on by default. Seems to me that cascades should only hap

fieldsets in newforms

I am trying to use fieldsets and newforms, looking at the newforms- admin branch it appears as if support will be included in the admin, but I am not sure of how to integrate this into my custom forms. Is the following possible / are there plans for doing something like the following? {{ form.a

Have you tried the SERVER_EMAIL setting in settings.py? For me that did the trick SERVER_EMAIL = '[EMAIL PROTECTED]' Without that it was sending the exception emails from [EMAIL PROTECTED] which my shared provider (webfaction which I highly recommend) did not like. jrs On Jan 3

Re: TEMPLATE_DIRS relative to project?

I have solved this by using a settings_env.py file. At the top of my settings.py file I have from settings_env import * then inside settings_env.py I define MY_BASE_PATH = /absolute/path/to/project/ so that inside settings.py the template becomes TEMPLATE_DIRS = ( MY_BASE_PATH + 'templates
