#django

They aren't bad, but they could be a little more verbose

yeah

only wrote the app last week... c'mon! :P

he says to the guy in the $6000 suit ... C'MON!

Does it work for views that are not forms?

RoboHak: well, for that I'd normally use sniplates...

My original problem was that django-crispy-forms does not work for detail views

FunkyBob: What are those?

same idea, but not form specific

I took the work I did in sniplates [which has a different form tags approach] and came up with formulation last week

I'm surprised there isn't something built into django to handle this

Is the standard way either custom templates or custom widgets?

standard way to control form rendering?

widgets in code

AIUI, the core devs agree it's not good enough, but so far all the alternatives were too slow

I haven't tested yet, but I believe formulation should be quite fast

what would be a good name for this function that took n as a parameter? return "abcdefghijklmnopqrstuv"[int(n)]

with wxyz added obviously..

huh?

plucking the letter of the alphabet by numerical index

ah

so it's like chr(ord('a') + int(n)) ?

yeah looks to be

def letter_from_int(n):

?

get_letter()?

On using a RadioSelect it returns the __str__ value for a given Model. Whats the best path with a custom widget based on RadioSelect to choose a different field from the input QuerySet?

that code is good FunkyBob . it does what i need quite nicely

theneb: actually ,as the docs and the tutorial say, it uses __unicode__

theneb: but if that's not present, Python will fall back to __str__

FunkyBob: Okay, if that's within the model I'd like to leave that value alone. It's just for one widget that I wish to return one of the other fields.

theneb: RadioSelect takes a renderer object, check out how RadioFieldRenderer works.

Yes, have been going through that mattmcc. The Renderer seems to have the __str__ field value and not the direct access to the queryset row

Oh, it's a ModelChoiceField? That class has a label_from_instance method.

I have a self referencing foreign key. Is there a way to find the related object that doesn't have a self reference?

not sure how to say that properly

Is it nullable?

yes

So filter on thatfield__isnull

Agian with examples! http://dpaste.org/GvkOc/

filtering on null returns all the top level subnets so thats a no go

I need the top level in relation to the subnet I'm looking at

If this is a tree structure, I highly recommend django-mptt or django-treebeard.

Otherwise you're working way too hard.

I guess it could be seen as a tree but I really only need to know the top level parent of a subnet..I never really need to traverse a tree per say

but maybe I am working too hard and should go get a drink... :)

What you're describing _is_ tree traversal. Finding the root given an arbitrary branch. Without storing tree data, you'll have to recursively query every node.

crap. ok...either of the two suggestions easier than the other for this simple traversal type?

v0lksman tree data structure in a database = nested set model

look into it

It's a single step operation in both apps.

mmm... nested sets :)

Any given node will have a get_root method.

:)

yeah..just realized I can't modify these tables

Well, then you're stuck looping through all the ancestors of your node until you find the root one.

http://dpaste.org/7E4KP/ any reason obj would return blank? does it get destroyed if the attr doesn't exist?

Missing return statement?

BTW, bare excepts are bad.

it should only return if masterSubnetId DoesNotExist

yeah I was going to qualify it once I proved the concept to myself... ;)

"should" does not mean "will"

But it needs to keep that return value all the way back out your recursion chainn.

how does one do that?

With the return statement you're missing.

wow... what a way to spot a bug

Say you're five levels deep. The innermost invocation returns the value. But then the one that called it doesn't return anything.

So the fourth, third, second, and first invocations don't receive anything, and you get None.

It might be more clear if you used a while loop instead.

hi. if i need to test a view that should force file download as an attachment, how would i go about it?

Check the response headers?

hmm. i was actually hoping i could use Client to download and parse the file

Oh, then the fact that it's an attachment isn't relevant. Just look at the response body like you normally would.

thanks

The Content-Disposition handler is just a hint to browsers, it doesn't affect how the rest of the response is structured.

s/handler/header/

thanks guys...got my recursion working...!
