DjangoBot: #django

so django.contrib.auth.models user object says it only takes alphanumeric/underscores and whatnot. If i want people to be registered by email address should I just write registration view that automatically makes a random "username" on account creation (they only supply email address/password) and when they login with an email address the view is User.objects.get(email='email')?

__machine: jquery hides content for me without any flicker

i'll check that out. thanks.

how can i run some useful python startup code when 'manage.py shell' is run? (using ipython)

PYTHONSTARTUP=~/.pyrc

and then put stuff into .pyrc

Yuji_: yep, random username on creation - you could also write an auth backend to get the right user for you

i think

have you also used YUI SmileyChris ? find jquery less bloated?

Yuji_: http://www.djangosnippets.org/snippets/74/

sterna: well i use python for non django stuff... i'd like to add common debugging variables ex. 'fs=Foo.objects.all()'

__machine: looked at but haven't used. Jquery fits my mindset and needs

mamato_: there is /nothing/ that runs only on manage.py shell

aha

so you cannot do it for just that

i suppose you can patch your own manage.py

__machine or set the hidden part display: none in CSS initially and then toggle it later with js

I have a Model meant to log activity across my project (various things being submitted or updated with datestamps and user.id's and such) would it be appropriate to have a method of the logging model act as the function to do the .save() of new records related to that model? It seemed like a logical place to store the generic functionality like that, but maybe that's a decision I'll regret...?

manage.py is magic :(

illustir: that means people without JS will never see it

oh sorry

EyePulp_: we have managers for a reason :)

managers... that name rings a bell.

one sec

mamato_: perhaps you should just have a test script you run?

btw, does anyone know why model validation fails with http://dpaste.com/38682/ ?

i think i'll have ipython run whatever startup.py script is in current dir

apparently, you can't use order_with_respect_to on a self-referencing foreign key?

sterna: not surprising

how would you go about creating a tree of categories?

sterna: you need null=True on that FK too

of which top-level ones don't have a parent, but others do

i used to have that, but i fiddled with it

now i'm looking at the code and it seems it's not really trivial to support that kind of usage

sterna: check out mptt

so it wouldn't be a def within the model class, it would be class Foo(models.Manager) outside of it.

what's mptt? :)

aha, found it

hey everybody

has somebody used mptt yet ?

SmileyChris: but i suppose this won't work with admin interface?

Yuji_: satchmo uses email as username and it seems to be well integrated. take a look at the source.

another q

onetoonefield seems to be deprecated according to svn docs

are there any clues yet about how it's going to be used in the future?

no

sterna: yea, there are some

sterna: check the mail archives - malcolm explained it

thanks again

it's not going to be deprecated from the sounds of it, just simplified and therefore potentially not backwards compat

robhudson: thanks. Its funny that the reason i'm doing this is because i'm new to django/programming and could not understand exactly what satchmo is doing

if i have a datetime in model e.g. DateOfArchive, and want to filter it by year should i write e.g.: invoices.filter(DateOfArchive.year=2007) ?

or something, somehow else

of course not

the docs clearly explain the various filter options like that

Magus-: thank you, you rule!

I'm having a really weird problem.. I just syncdb'd into a clean database. Now when I try to go to a model in my admin, I get the error 'no such column: products_grouping.id'

so um, django isn't creating the column maybe?

more likely you broke something ;)

yeah hmm

well all the other models are working fine

haven't touched the django source

pastebin more info

Is it possible to make Typogrify not parse stuff in pre/code elements? My code samples are getting smart quotes. :P

I get this: http://rafb.net/p/kWp0Ct72.html when I'm doing: current_fights = all_fights.filter(end_date__gte=datetime.date.today())

Magus-: I found the problem. had to do with ordering

couldn't order by a foreign key

sure you can, you just have to do it right

Well I just did order by the field name of the foreign key

and it came up with saying that the id column doesn't exist

because it won't be included in queries

you need to do fkeyname_id

aw okay

One of my models is missing the 'id' primary key, why might that be? I have verified that it is inheriting from models.Model

Magus-: It's actually a m2m, any way to do that? I know I can't call methods in ordering so that wouldn't work

None of the other fields have the primary_key parameter either

Ignore my earlier comments; found this: http://www.djangosnippets.org/snippets/381/

aficionado: does it have a OneToOneField on it?
