order_with_respect_to and edit_inline in MR
Hi, I switched my code over to M-R this past weekend and was surprised that it went pretty smoothly. There are a couple things in my models that aren't working anymore though. The first is order_with_respect_to. I have an inline edited object that I want to order with respect to its related object. I have this in my model: class Link(models.Model): date = models.ForeignKey(NewsList, edit_inline = models.TABULAR) ... class Meta: order_with_respect_to = 'date' I have dom-drag.js in the appropriate place, but ordering isn't working in the admin interface anymore. I could probably figure this out by diving into the source but was hoping someone could give me a quick answer here first. Even when I remove dom-drag, it doesn't display an ordering box like it used to. The other thing that doesn't work anymore is customizing the edit_inline interface by subclassing BoundRelatedObject. I remember mention back in February that Jacob was working on changing this, but I haven't been following the list closely enough to keep up with this and I can't find anything from searching the archive.

Re: MySQL + FastCGI + Dreamhost = Trouble with foreign key in admin
Okay, I figured out what the SQL query is that's causing this error: INSERT INTO `polls_choices` (`poll_id`,`choice`,`votes`,`_order`) VALUES (7, `not much`, 0,(SELECT COUNT(*) FROM `polls_choices` WHERE `poll_id` = 7)) ERROR 1093 (HY000): You can't specify target table 'polls_choices' for update in FROM clause According to mysql, it's version 5.0.18-standard-log. This error occurs if I issue this query directly to my database. So, is this a mysql bug, or is there something obviously wrong about the query? This is a big problem for me right now as it affects all foreign keys edited inline in my models. Thanks for any help anyone can provide. I'm supposed to have this installed to show the prototype to a client on Monday and this is kind of a show stopper.

The problem I'm having right now is that there seems to be no elegant way of updating the dictionary bound_related_object_overrides in admin_modify.py to let it know about additional view types. I can, of course, edit it directly in admin_modify, but this isn't very nice. Any suggestions? All ideas I can come up with involve changing the admin code. Colleen

I basically derived the same solution on my own, except that I added a new section of the change_form template that could be overridden. Colleen
Re: custom admin view for edit_inline object
So I'm replying to my own message here, but I want to tell you how I
did this in case
a) someone wants to show me a better way
b) it could be useful to someone
Again, what I'm trying to do is customize the way inline-edited objects
are displayed for one of my applications (without affecting any other
application).
First I changed line 52 of
django/contrib/admin/templates/admin/change_form.html to read:
{% for related_object in bound_manipulator.inline_related_objects %}{%
block related_object_display %}{% edit_inline related_object %}{%
endblock %}{% endfor %}
(i.e. I added the block and endblock tags).
Then I created another change_form.html file in my template directory
that simply contains:
{% extends "admin/change_form" %}
{% block related_object_display %}{% include
"admin/news/edit_news_inline" %}{% endblock %}
admin/news/edit_news_inline simply points to my custom template that
contains the code I want. I'll customize the url rewrite to point to
the default change_form for all applications, but my news application
will point to my new change_form.
Does this seem like a reasonable way to do this? I still don't quite
have a handle on all this so sometimes I feel like I'm doing things in
a very convoluted way.
Thanks.
Colleen

Hey Colleen,I'm not sure this answers your question, but feel free to make up yourown settings. See the docs here: http://www.djangoproject.com/documentation/settings/#creating-your-own-settingsAdrian This isn't exactly what I'm looking for. This would work, but it doesn't seem very elegant. I want the administrator of this site to be able to modify nearly everything through the admin interface. At the moment, I'm thinking about just creating a Configuration class for my app (and forcing it to be a singleton) and storing that in the database. This still feels a little clumsy, but I think it will work. Colleen
scheduling capabilities?
And another question quick on the heels of the last one...Does Django have any built-in scheduling capabilities, like "run X every 15 minutes"? Or should I stick with Twisted for that? Thanks again. Colleen
application level settings
Hi. First I want to thank everyone for answering my really basic questions. The responses I've gotten here have been extremely helpful. I'm starting to get the hang of Django a little bit and I love it so far. My latest question - I want to have some settings that apply to an application (not the objects within that application's model but to the application as a whole). For example, I want to have options like the maximum number of objects that should be displayed and various display options that are set by the system administrator through the admin interface. I know I can do this by writing some basic Python code and a custom view for the admin interface. This seems like a more general problem though, so I was wondering if Django has some built-in way of handling this. Thanks! Colleen
Fwd: customizing appearance of foreign key edited inline
I'm resending this question because I'm still having trouble figuring this out. I'm interested in customizing how a inline-edited foreign key appears in the admin interface. Is there some way to do this? Thanks.-- Forwarded message --From: Colleen Owens <[EMAIL PROTECTED]>Date: Jan 4, 2006 1:17 PM Subject: customizing appearance of foreign key edited inlineTo: django-users@googlegroups.comHi, I'm having trouble figuring out how to customize the appearance of a foreign key that's edited inline in the admin interface. For example, if I wanted to change how the poll choices from the tutorial are displayed, by suppressing the number of votes, or changing the order in which the votes and choices are displayed, is there a way to do this? Thanks. Colleen
Re: help passing data from view to template
Okay, yeah this was a dumb question, foolishly asked before I got
through part 4 of the tutorial. I see now that calling get_link_list
from within my template will do what I need. I didn't realize that
get_link_list would preserve ordering.On 12/21/05, Colleen Owens <[EMAIL PROTECTED]> wrote:

this data from my view to the template.
I tried this and several variations on this, but I'm not properly
accessing the variable keys that I'm passing into my Context object. I
guess what I really don't understand is what can be passed into the
