Anyway, I don't think there is anything "wrong" with that really. But saiyr said that using a domain as a base package provided no benefit.

gurft: you need to make sure that the db structure of the raw SQL match the db structure built with syncdb

I've only ran into a name collision issue once, and it could have certainly been avoided. However, the possibility existing is what brings me to that type of organization.

Even if they are stored in me.monokro.package format, that doesn't even really mean they have to be imported that way. Also, mattmcc - do you use virtualenv on production servers? I haven't looked into using it yet, although I do intend on it.

Yep.

hmm

mod_wsgi makes it pretty dead simple.

That could actually solve an issue I've run into.

is it possible to group model objects by some field and then group each result again by another field?

And since we have different clients on different Django versions, not using virtualenv would make the web server config somewhat more of a headache.

I can group by the first field and then I'm stuck http://dpaste.com/170239/

mattmcc: Yep. Plus, my webapps are hosted on Amazon EC2 - so I'm always afraid of the server crashing because it resets the entire hard disk to base install upon rebooting the servers.

Well, that's what EBS is for.

I have a script that reconfigures the system to solve that, but it's a pain.

Yes, I have all of the apps and templates on EBS

And you can make your own AMI of your server config.

Should never have to reconfigure an image.. :)

is it best to use model form when you can?

or just use Forms?

Yes. I know that, but I didn't want to delve into that process until I figured out how to minimize the need to change the AMI... Virtualenv seems like the perfect answer.

There's an option to have an instance use EBS for the root filesystem, iirc, but we haven't looked into that.

BlueSilver39: When you can use ModelForm easily, use it.

BlueSilver39: use ModelForm if you can.

ok

I've wondered about that, mattmcc. That would be nice.

Linode's stack scripts are pretty cool too.

The gap between EC2's 'cloudness' and that of VPSs with APIs like Linode and Slicehost seems to be closing over time.

i never really know what to do with VPS databases

anyone ever clustered postgres?

Hmm. I haven't looked into that, mattmcc.

so i had this great idea to leverage django in a statistical analysis project, it's working amazingly well. only issue, is when i have to import my data, as I load sourcefiles (alot of them, and with a combined count of > 200k) memory usage baloons out of control. seems like objects aren't being released when I'm done with them. can someone point me to anything on memory managemnt with django? or is that out of scope...

bwooceli: As soon as you say 'statistical analysis' I would say 'stop using models'.

Python generally handles memory management...

if I have a ForeignKey on Users and a ManyToManyField on Site in a model... I wonder if I can class Meta: unique_together=('user', 'sites')

DBs (Well, postgres and oracle) are very good at doing complex math on their data.

oliland: there are a couple of clustering tools for pg

mattmcc: Model data is fine for a base dataset for statistical analysis

I'd move it all into stored functions.

mattmcc: lol i know. but once the data's in there, it really works well.

"easy" sometimes isn't a good enough excuse to do something.

really the dataload is the only time i run into problems

i'm using csv to read data into a temporary model, then i have a method that takes the temp entry, cleans up some of the fields, sets it to a new model instance, saves and returns.

but it's like the method just leaves the model instance just hanging there, and after 200k+ rows, it dies and i have to restart (picking up where it left off)

Do you have DEBUG on?

mattmc: erm, yes

Turning that off is a good first step.

mattmc: oy. trying it now. my shell instance took up a benchmark size of ~12M, and would baloon to 500M after loading a few files. it's now expanding at a rate of about 200K per file loaded.

gdam it's always something simple like that.

With DEBUG on, every query is added to a list (connection.queries)

So while turning it off isn't a silver bullet, it'll certainly take a chunk out of the problem.

not that it's news to anyone here, but django is unbelievably useful. i'm an analyst, but this is letting me build an enterprise class tool in an amazingly short time. take that .NET

Heh. My friend who wears a variety of Oracle hats (analytics, ETL, architecture..) likes Django, but for analysis/reporting, he sees it simply as a UI tool that presents the data crunched by his Oracle package.

bwooceli: you're right, it's not news to us... but we do derive pleasure from your joy :)

i'm using it to build a reporting tool

Where my UI gives him parameters, he runs a function, and I get a big DBMS_OUTPUT blob to play with.

mattmcc: makes sense

It's analogous to why geodjango exists. It'd be silly to write all the Python code to do at the application level what postgis does at the DB level.

.

On the other hand, there's plenty of stuff scipy can do much easier than most DB libraries offer.

yeah i'm using pygsl

im a little confused by django.contrib.gis - is this the same as geodjango?

Yes.

so, geodjango.org docs which say to import geodjango can be substituted with contrib.gis?

warz: I'd assume as much. I don't even have a module called Geodjango

ImportError: No module named geodjango

Can someone bail me out of a situation? Error overriding the Comments model default manager.

Does the comments app have a custom manager?

hmm

good question

yep

the error itself is a rather basic one tho

self.model == None

Try extending django.contrib.comments.managers.: 252 seconds]

20:00 -!- PPeeps [~Owner@2001:470:1:b8:20c:29ff:fe32:c286] has joined #django

Try extending django.contrib.comments.managers.CommentManager

Sorry, bad paste.

kk

What was the error?

Oh crap I just realized the problem

Have a friend looking to fill some positions for bay area located devs experienced with python/django/jquery/mysql, PM me if interested or know of anyone thats looking

PPeeps: you need a cam guy?

cam?

yeah, you know. like live cams. sex shows. etc.

Is pythonw.exe the standard name of Python for Windows' executable?

subsume: na, well maybe..... haha no

monokrome: apparently the problem is I'm an idiot and for some reason thought it was a good idea to explicitly set Comment.objects. lol.

PPeeps: oooh django. right.

sorry

haha no problem, its not even actually me looking. they just were having trouble getting qualified devs for the position

weird.

what's qualified?

PPeeps: ^^

i'm not sure exactly, just from what i heard they were lackluster

thats all

PPeeps: righton. what is the going rate for a djangonaut out there?

i'm not sure, i could ask tho

PPeeps: what kinda firm is doing it? some ecommerce stuff?

subsume: one sec
