hi guys, can anyone help me with something?

Only if you ask

i hava a post model that i'm rendering, but this post can be voted, and I needed something that know that this post has been already voted by the user on the template

i have*

well, you would like vote to be many-to-many model on user and post

and grab it in your view

yes, i have a posts and a votings app

well allow_vote = not Vote.objects.filter(user = request.user, post= current_post).exists()

what the problem?

but I'm rendering a lot of posts

then you may try annotate()

hmm..

i'm doing one on my PostManager

but it's to get the post reputation

hi guys I'm new to django and I think i just might have correctly linked psql with django, what would be a good way to check that?

darkmutt: can you do python manage.py syncdb

that means its not correctly linked, although it didn't splash an error at 127.0.0.1 as it did earlier now it says peer authentication failed,thanks siecje ill figure something out i think :)

syncdb creates tables in your database for your models

darkmutt change auth method

new to all of this here so i have yet to learn what that exactly means

pg_hba.conf

it's some funny postgress auth methods, they say you better change auth method to md5 if you are novice

well i had to re-install postgres from batch installator run file and it seemed to fixed all steps

hmmm i have to admit i was wondering why the tutorial was telling me to change it to md5 without even trying to explain as to why i should do it

hello, good afternoon, salutations (and all that stuff): I'm wondering what is the best/good way to populate a form with a select (drop down) of table names, i.e. model names?

i'm aiming for a couple step wizard for doing CSV extracts, 1) select the table/model, 2) select the columns, 3) get the file

i'm looking for something like ModelsChoiceField, i think, noting it's Model(s) plural

and i'm looking to select from the models, first

I'm trying to set things up so I can use coffeescript along side django

but every solution I've found so far requires node to be installed on the application servers for the collectstatic step

is there a way around that?

Anyone know how I can teach django that accessing files in /tmp/ is not a SuspiciousOperation?

The user doesn't upload anything to /tmp/, I'm taking the user uploaded file, running some imagemagick commands on it, and then re-storing it on the FileField.

donspaulding won't be better to use stringIO ?

I'm shelling out to imagemagick, which wants real filenames.

but before i switched to it i was operating with tmp alright

ah, i should do it too some time )

guess it much faster than with PIL

Do you use django.core.files.temp.NamedTemporaryFile ?

Fuyou: I didn't switch for performance reasons. I needed to be generating a CCITT Group 4 Compressed TIFF image, which PIL couldn't do.

Fuyou: I didn't know that existed, so no. But I'm looking into it now...

Well, i do have performance reasons )

I force all images to be converted to png

Fuyou: I was just saying I don't know that it's any faster to shell out to IM instead of running PIL in-process.

I guess python is just not language for strong math

I wouldn't know, I'm not human for strong math ;-)

Has anyone done a RPC to rabbitmq via Pika in Python from a django view?

Is it possible to do such a thing?

I tried doing such a thing and got a connection closed error.

in a class based view that gets an id from the url how do I access the id?

Siecje you mean some like /mysite/mymodel/4/ -> 4 ?

right

you make regex with capt group and pass group name to view

(?P<pk>) <

or

(?P<field_id>)

and then use slug_field

or there is something unusual for model-based view

@Siecje

merb: Fuyou where do I capture the named regex though https://dpaste.de/AbX7b/

capture?

ouh

its wrong

to put it in get_context_data

when it is a pk

you don't need to do anything

it just works
