Colliding?

What’s up everyone?

woops

Hi guys, I want to start using Sass for a django project of mine that I've been working on for a few years? Whats the best way to about doing this?

shogundynamite: heroku, elasticbeanstalk?

Linode VPS

So I have this javascript function: https://dpaste.de/sRVw and the response I am using is "return JsonResponse({'purchased': True})" how do I properly find out if purchased is set to True in javascript? I thought data['purchased'] would be correct, but it does not seem to be.

shogundynamite: oh, i misread your question

shogundynamite: Asset managers like django-compressor or django-pipeline might be helpful.

mattmcc: I saw some of those but the ones I found weren't very popular, I'll check out them out now.

found out why, i didn't have the d in purchased :(

what is the pep standard for naming variables/json like that? just use present tense always?

guess i should use {'success':True} or {'success':False} would be best, so it will be universal

Hey, so I can write a query on the model tables in PSQL, but I am having trouble translating to the Django ORM. Anyone mind helping? https://dpaste.de/pv5s

dheerajchand: Crime.objects.values('ward').annotate(cc=Count('pk')).values('ward', 'cc')

mattmcc: Do you mind if I deconstruct that and walk my way through it with you?

It produces essentially the same query.

You can see the result by doing qs = ^; print qs.query

vyscond, not redis ... django session

For all Crime objects, using the value of the field called `ward` as a key, create a value called `cc` that is a Count of all primary keys in that grouping, then show a list of JSON, where the property:value are ward: ward_id, cc: cc

what?

dang`r`us: What do you mean by collisions?

nevermind, I'll get back to that issue once I solve everything else here

okay so real quick

mattmcc, request.session is more or less a dictionary, right? so, when putting something in there, should I prefix my key with my.app.fqdn or something?

to avoid stepping on others

Oh. If you're worried about your keys being overly generic, I suppose it'd be prudent.

Like I probably wouldn't set request.session['data']

yup yup

this

mattmcc: I tried readin the documentation for the aggregate/annotate functions and it was just Esperanto to me

Your example made it more clear

guess I'll prefix stuff with myappname-

Any chance you can refer me to a really idiot level tutorial?

should be safe enough

here i have interesting problem guys - probaly wrong channel to ask it, but if someone could point me where should i seek support than would be quite enough

so here goes...

i want to allow users to create their avatars

by selecting various options

stacked on top of one another as layers

for instance bottom layer would be heads with different skin colours

then few different faces

then hair on top of that

i have few - let say - sprite's grids for that

and through simple css modifications im aligning them within some viewport

to create final image

but i'd like to store resulting avatar as flat picture

for displaying it on subsequent occassions

and i wonder how can i achieve that

any ideas ?

that sounds like a job for <canvas>

arlekin: so, once a user is happy with what they chose, you submit that information to your Django application on do the overlay there

MarkusH: so basically you are sayin i should send offsets and do same thing on the server side ?

dang`r`us: could you elaborate, im not familiar with <canvas>

arlekin: that's what I'd probably do. No idea if there's any front end side way to create the image

well <canvas> is for bitmap manipulation basically.

it's almost 5am here so not giving a detailed intro .....

but you can goooogle it.

arlekin: http://www.html5canvastutorials.com/advanced/ht...

dang`r`us: same here, im not asking for tutorial ;) just wanted some hook

i'll look into canvas then

MarkusH: you don't know perchance any lib for such gluing layers of pictures in python ?

arlekin: pillow

that does *all* the image magic in python

former PIL

MarkusH: reference to imagemagic intended or not ?

kind of

i see, i'll into that either then

If I have files that people are downloading from my website, what is the best way to handle generation and serving? Right now we have a downloads folder that gets zipped and cleaned for each set of files generated.

if you use canvas you probably won't need pillow

I mean it all depends a bit on your use case but personally I would probably compose it all in the browser, just using canvas

i guess the perfect thing would be to kinda "screenshot" content of designated div

dang`r`us: the composing part is easy, since i already have my grids and its matter of moveing <img>'s, i worry about producing result though

arlekin: use the toDataURL() on canvas and send the data off to Django

Jameswine: have a look at x-sendfile

Jameswine: https://github.com/johnsensible/django-sendfile

canvas looks promising since it has method for drawing images on it, so if i figure out how to use part of image i should be golden

for future reference, who should i ask for such things ? #web-design or something ?

btw thanks MarkusH dang`r`us, you've been of great help

gotta love irc - saves your butt when you don't necessary have weeks/eternity for waiting for answer on SO ;)

:V

'night

arlekin: you're welcome

is there a way to render something like this in a view: render_to_response('django.contrib.auth.views.login', {'template_name': 'login.html'}) ?

jtri: what are you trying to accomplish?

MarkusH: avoid using the url pattenr to specify everything...
