danfairs, overall, do you think going with aws to start is alright?

It'll work, and loads of people use it - the learning curve is steeper than some others though.

What does your app look like? Is it a simple Django web site, or is there more to it than that?

velcrow: In particular, do you need to run custom services etc?

Simple website

No custom services

Right, so if you're trying to keep it simple to start with then something like Heroku's plan might be the best - if you don't want to get involved in configuring web servers etc.

danfairs, I see, ok, ill look into it again

They are more expensive than AWS, for sure, but factor in the amount of time it'll take you to get everything set up on AWS.

I think there's a free tier on Heroku - that might be good enough to start with, at least?

sorry everyone i know you missed me buy i was away

s/buy/but

danfairs, I heard there are problems on heroku with django though

ill need to investigate mor

hi guys, any suggestion the way to iterate

hi

i am developing something with django and postgres

quite often i come across this

InternalError: current transaction is aborted, commands ignored until end of transaction block

i come across that too in development shells

uffs: i usually just exit the shell, i would also like to know how to prevent it or to close the transaction

hmm

i often see it in shells too

but not only in shells

which bothers me because i know it means something went wrong with postgres

but it's hard to debug

wrapping problematic function in @transaction.commit_manually kind of works to me, but i guess it's only treating the symptomes

besides having a major drawback of me having to put try: ... except Exception block there

obscuring any other error that may occur in that chunk of code

i would think there is some common explanation to those errors

uffs: Usually it means that something went wrong at the postgres level (eg. an integrity error) and the connection's transaction wasn't rolled back.

uffs: It *probably* points to a bug in your app

Have a look at the postgres server log, and see if there are any clues in there.

yes i only get that when messying around on the shell

sorry didn't see your reply up

hi! I got a questoin..: it's possible to filter in Count() on *_set ?

(m2m)

hi

I've got a little problem with the formwizard : I'd like it to remember the data the user has entered for the current step even if the user has went back to the previous step

is this doable ?

hi all, just testing my irc on my mac, works good right?

NBhosting: looks even maccy :)

haha :D

i have a custom primary key field https://gist.github.com/atlasloewenherz/bd05f97... which try to generate ids via the AutoField, this seems to be half working: 1 i can create dummy models containing my custom field, but the value of the key in the database is not the one i want for example when listing my models i get the key showing as : 2013-1, 2013-2.... but in the db/table/id the values are just 1,2,3...

Im Gerd from the Netherlands, php programmer ditching pph and going for python/django :D i hope i dont bug you guys to much with my newbee stuff haha :D

Hi Gerd/ NBhosting congrats for choosing the blue pill :)

Hi, I am using the django rest framework and the DRF any permissions library. However, the any permissions library isnt' working. I basically copy pasted from their docs but it is not giving permission.

I need to represent a typical "category tree" structure where the leaf nodes could each have multiple parents. It seems a graph datatbase like Neo4j is a good way to do that. On top of this I also have to handle users, but neo4django doesn't have support for user permissions, so it seems I'll have to use another database for that - but neo4django doesn't have proper support for doing that.

I'm basically in between a rock and a hard place. Has anyone got any tips?

hello everyone

i created a virtualenv when i need to use libjpeg-dev

i install libjpeg-dev into the operating system

how do i make it availlable in the virtual env

?

jenia_: you should use a python module that exposed libjpeg library

i dont get it

Hey guys, I need some advice on building a feature for a django website. So basically, its a plugins system. I will create numerous plugins for an application. So think of it like an iPhone and the app store. Just like that, I'm creating apps/plugins for the website. It gives it additional functionality. Any tips on going about doing something like this?

libjpeg a C library, if you want to work with images in Python you should get Pillow

Pillow shading is frowned upon in the art community...

IOError at /admin/shop/product/

decoder jpeg not available

home/jenia/Documents/sergey/01proj/local/lib/python2.7/site-packages/PIL/Image.py in _getdecoder, line 385

this is what i get

did you re-install PIL in the virtualenv after installing libjpeg-dev?

jenia_, if you aren't a purist, just put a symlink in your virtualenv's site-packages to your system PIL. Otherwise you'll have to build PIL from source in your venv

okay thanks so much

this this:

sudo ln -s /usr/lib/i386-linux-gnu/libz.so /usr/lib/

jenia_, in my venv's lib/python2.7/site-packages I have a symlink: PIL -> /usr/lib/python2.7/dist-packages/PIL

jenia_, that's on Ubuntu, your paths may vary, etc

isnt it easyer to just install it with pip/easy_install

in your env?

NBhosting, have you tried it? :)

not with that one, but i do with others

you need a lot of dependencies and it isn't obvious what they all are

ah k, so thats why :D

it can be done sure

PIL relies on a bunch of C libraries

so u guys install the bigger once system wide to avoid glogging the env
