hi guys, i'm trying to find a way to filter the values of one foreign key field by another foreign key field in a django admin form.

am i on the right track by using SimpleListFilter ?

I'm not sure anyone understands what you mean, lucidm

hm, ok. So say I'm adding a new entry for a model: episode. it has two foreign key fields; Season and Show.

so.. you're trying to do a cascading select?

after selecting the show, only the relevant seasons should be listed

where selecting in one field limits choices in the next?

yes, that's it

in that case, no.. SimpleListFilter is the wrong device

the fact you _can_ select the wrong season for a show indicates your schema is flawed

ok, that's true

normally I would only have the 'season' be a foreign key, which in turn has the 'show' as one. I guess I got carried away making the admin forms.

you shouldn't be putting this much work into admin

it should be going into your sites management interface

having quite a noob moment

when aren't you? :P

my static css files are being correctly accessd in my templates

but my images aren't

media?

feel the burn eh FunkyBob P

:P

or static?

there you go!

haha

well i assumed that images were considered static?

(it's not user submitted content)

oh gosh i worked it out ..

limbera: then it's static

base.html had no {% static '' %}

declarations

is it part of your deployment -> static

i was looking through my homepage.html template

which extends base

and i forgot to swap all the base elements from hardcoded elements (when i was designing the HTML) to proper static django ones

the ultimate N00b moment

FunkyBob: will you be at PyCon AU?

MarkusH: I certainly hope so!

:)

you? :)

of course

do you have acoom etc sorted yet?

only, since i'm planning to travel sans family, we could split an appartment perhaps?

Question. Can someone point me to a document, or explain why Django Form Wizard (http://bit.ly/1BWKPg4) uses "<table></table>" in all the template examples?

halfnibble: because {{ form }} defaults to {{ form.as_table }}

@FunkyBob Are you serious? I've been writing CBV's and templates and have never needed to use "<table></table>" before. Does forms.ModelForm with a CBV default to something else?

halfnibble: you never need to use table... you never need to use the html rendering aspect of forms at all...

Why or why does Django swallow template errors from an include? {% include "blah.html" %}

*Why oh why?

darkpixel: it shouldn't

Hrm. That's not encouraging. ;)

halfnibble: CBV have fuck all influence over your template/form rendering

That means I've done something wrong on the last four projects I've pushed out.

darkpixel: what makes you think it is?

@FunkyBob Fascinating. Thanks. This is what I needed to know. The documentation just threw me off a bit.

halfnibble: this is irc, not twitter... no @ here

Sorry. I'm a bit new to IRC.

well, now you know.

Thanks again. :)

FunkyBob: no, I haven't figured out the accommodation yet.

FunkyBob: I have a 'person' table that I {% include %} all over the place. I accidentally fat-fingered {% end for %} (yeah, with the space) inside the person table. Every page rendered perfectly, except the person table wasn't included. It's like the include errored out because of the typo, and Django included "" where the table should have been.

darkpixel: which django version?

how do i access django.contrib.auth.model.User in a data migration?

`nik`: same way you access any model?

FunkyBob: 1.7.4, although I hear 1.7.5 came out this morning.

so that means you're using my version of the include tag

Hmm...maybe I should do a 'git blame' before ranting. ;)

FunkyBob: alright. i was just asking because internal models are accessed like: Item = apps.get_model("main", "Item")

`nik`: all models are accessed that way, aren't they?

which is how i thought u normally accessed models from a data migration

darkpixel: haha

darkpixel: nah... rant on... just means I know more about how to fix it

so for User i would do.. apps.get_model('django.contrib.auth.models', 'User')?

no

get_model('auth', 'User')

app_label works the same for contrib as any other apps

okay.. i guess i don't understand that, but thanks

don't understand app_label ?

yeah

basically it's the name of the module, by default... so for "django.contrib.auth' it's "auth"

interesting.. i didn't know there were shortcuts like that. i'll look into app_label

if you app was 'foo.bar.baz' its default label would be 'baz'

FunkyBob: Hmm...looking at the source, it looks like IncludeNode swallows errors unless 'context.template.engine.debug' is True.... is that frobbed by DEBUG = True in settings.py?

darkpixel: engne? you sure you're using 1.7? that sounds like 1.7

1.8

Oops--I'm running 1.7.4, but looking at HEAD.

FunkyBob: LOL! So it looks like I need to explicitly set TEMPLATE_DEBUG = True in 1.7.4

FunkyBob: Yup--that's it.

Incidentally, that setting's going away in 1.8.

actually, for the user model you want django.contrib.auth.get_user_model, `nik`

MarkusH: that's if you want the user model... nik asked for auth.User specifically

well, if it's swapped out you can't use auth.User anyway

ah, missed the beginning

yes, in a data migration it's apps.get_model

Hey so I'm using django EmailMessage(subject, body, from_email, to_mail, headers=headers) and then adding these headers headers = { "From" : from_email, "Reply-To:" : from_email, "Content-Type:" : "text/html", "charset" : "UTF-8"} and getting this raw text https://gist.github.com/jakesyl/94e78e5005436b0...

also the email is showing <b> instead of formatting it
