Nelluk: don't you just want dict['SubDict'].get('SubDictKey') then?

igorline: yes, not filter it for null=False

SmileyChris: well, not if dict['SubDict'] might be an object with a get method :P

Sounds like a case of trying to be too clever.

yes

I would just break it into two lines

SmileyChris: yeah. i was looking to see if there was a one-liner that would silently give a default if the first key didnt exist. but two lines is fine

but i have a related question on a five liner: https://dpaste.de/VXzU

Nelluk: so you want dict.get('SubDict', {})['SubDictKey']?

er, .get

heh thats clever

ah whatever

i'm not actually sure what you want :P

that would do it i think

SmileyChris: only if you can guarantee d['SubDict'] yields a dict-like object

FunkyBob: well that's already an assumption

yeah that is an assumption

oh, wait... I misread the question

Nelluk: so you want json.get('Prices', {}).get('ItemPrice', ())

Heh, my tsak running every 45 seconds going to finish in about 9 hours

"will throw an exception if SubDict is not in Dict"

dict['SubDict'] will do that

which is what i said first :P

FunkyBob, but fields is a list, how do i filter it?

now we are all getting confused

snap!

not_null = filter(lambda x: x.null, Model._meta.fields) :)

what is () a shotcut for? i would have thought i'd need .get("ItemPrice",[]) to give me an empty List as default

() is a tuple literal

just as [] is a list literal

got it

and {} is a dict, though the same syntax can make a dict or set literal

FunkyBob: OMG HOW DO I MAKE AN EMPTY SET USING LITERAL NOTATION???

:)

I nominate ⁅⁆

ha

make people type unicode characters

Surely ∅ is appropriate then?

if there's a left and right half of it as two separate chars ;)

must stay consistant!

See, we should have jumped on using other characters for set literal boundaries:

«a,b,c»

⦃a, b, c⦄

(Erlang's bit syntax and matching is actually really cool, but we are drifting dangerously off-topic now… :)

I want to store an array as a model attribute. What would be the best way to accomplish this?

<JulianGindi> as no suggestions from elders, I propose to yaml it )

JulianGindi: just put it on the model? django's models.Model is like any other class

or you want to store the array in the database?

Jax: Yeah, I do want to save it in the DB. Should have been more clear

(I guessed later)

sounds fishy, but if you must, and performance is not an issue, then serialize it (if the content permits)

and put it in a TextField or just write your own field, ArrayField which does the serializing/deserializing for you

can you convert it to json?

Was there a TextField? I think its only CharField in models

no there is a TextField

Jax: Yeah I think I'll convert it to JSON first

Jax, ah you right, my bad

time for bed, gnite all

later

JulianGindi: why are you storing an array of data opaquely to your DBMS?
