is there a way to have django + selenium test different browsers for each tests?

FunkyBob: ok... i've been trying to debug, no luck yet. i have to close and re-open my application. i think there may be some kind of "read transaction" that is never closed (on my side). any idea how to force close?

rlrosa: well, you'll need to start by reminding me what you're talking about :)

which do you think is a better way to get started on django, the django docs 4 part tutorial, or the "The Django Book"?

Wolfram74: the 4-part tutorial

it's current

the "book" ... is being updated, but languished for years

FunkyBob: :) i have an external daemon that accesses the django db to check for session id before allowing stuff. when a new client logs in his newly created session id is not visible to my daemon's queries. the mysql does show the session id, and if i restart my deamon it also find the sid

FunkyBob: i'm looking into read transactions, may be the issue. not sure yet

the 4-part tutorial doesn't seem to mention anything about deployment though

Wolfram74: no... that's in the main docs, though

however, you don't need that for an introduction

so after the tutorial, the book, or just continue to wander aimlessly through the docs? because that second approach seems like it could easily become very frustrating

This may seem a dumb question but I'll ask anyway. Is there any prefered, or best-practices, or make-most-logical-sense place to put a virtualenvs when using virtualenvs to run a django app in production?

I tend to recommend reading over the contents page in the docs

and delving into parts that look interesting

I'm having some issues w/ gevent and postgres - I'm getting "OperationalError: FATAL:  sorry, too many clients already". I assumed I could call connection.close at places where the coroutine idles to free up connections, but it doesn't seem to help. Anyone have an idea?

cellofellow: not really... I have a particular layout that keeps everything together...

kanja: have you got the postgress "green" patches?

FunkyBob: I'm not sure! Do you mean the monkey patches gevent comes with?

FunkyBob: you know, I'm not actually seeing where I even use the monkey patching

could I have forgotten to actually gevent the psql driver

that would not be my finest moment

FunkyBob: I knew I needed to do this, but I can't find it in my code -I think I totally forgot about it

dur

FunkyBob: I've never done this in a django project though - where would you suggest the patch go? My guess is the settings file?

Hello django using pythonistas!

Once upon a time I used django on a daily basis. However for the last 3 years I've been using ruby and have lot touch with my python roots.

Along the way I picked up some great tools that I'm wondering if there are python counterparts for.

kanja: previously I've done it in my wsgi script

shadowshell: sounds interesting

I've noticed that accessing the property of self.request.body after it's already processed throws an Exception

FunkyBob: that makes sense

sudobangbang: and you're doing this because...?

is there anyway to get the request.body bytes later from somewhere else on the request object?

guard - Guard is a command line tool to easily handle events on file system modifications. Its pretty sick and watches my files for changes, then runs a series of operations that I dictate. This includes things like running tests related to the files that just changed.

Something like this is a must have for my workflow as I'm test happy.

FunkyBob: because I'm passing JSON and i don't want to create a QueryDict that i can use with my model form

Any good python alternates?

FunkyBob: because i'm passing JSON and i *want* to create a QueryDict out of it that i can pass to my model form

FunkyBob: yeah, i need to polish up my python chops and get back in the groove round here

sudobangbang: ...

sudobangbang: so don't access request.GET, request.POST or request.REQUEST

my second goto tool is capybara. its a general purpose testing api for driving selenium and other browser tools for integration/acceptance testing web apps/apis. lettuce seems nice for the bdd side of this, and there seems to be some integration efforts with selenium. but is this the goto tool in pythonville?

for BBD driving webapps^

FunkyBob: ahh, i see how that triggers everything. Now i wonder how i can conver my JSON into something that works well with QueryDict(s) and ModelForms....thanks

shadowshell: I've used "behave" or BDD... it's very nice

shadowshell: why do you want QueryDicts?

FunkyBob: behave, will check it. ty.

shadowshell: doesn't hurt that one of the devs is a friend of mine :P

FunkyBob: any efforts for integration with selenium or some headless browser tools like phantomjs or headless-webkit that you know of?

we've been toying with phantomjs...

I don't know where that's gone ... others on the team, yadda yadda

FunkyBob: gotcha, well thanks for the hint.

FunkyBob: because instead of writing separate validation for JSON-to-Model POST(s) i'd like to use the already existing ModelForms. So the thinking is if i can convert my JSON into a QueryDict

that looks like the QueryDict from a html form POST

sudobangbang: ah... you don't need to

sudobangbang: just pass a plain dict

FunkyBob: let me try that

FunkyBob: alright I patched psql - fingers crossed. Thanks for your help!

for a modeladmin i added a new field for its form just to display some data that is generated on the fly and isn't needed to be saved to the db

shadowshell, you can use inotify to follow fs events on linux. and there is python library for it, pyinotify

but when i click save it tries to save the field but obviously can't find it

do i handle this on the model admin form ?

kanja: no problem... I have a bunch of sites using gunicorn/gevent and psycogreen

FunkyBob: I want to get into it more - it seems so powerful

FunkyBob: I just don't do enough that needs the power

this time is websockets

power?

ah, well

yeah I mean I just don't need it that often

I use it for low memory footprint :)

huh

huh!

that would actually be helpful

however, we've a large site that'll be using it for SSE

is there a way to get stack traces while using it?

SSE?

Server Sent Events

ah yeah

yeah it's a pretty perfect case for that
