billy_maze: django can't use more than one database (not yet), so the question is somewhat useles

christopher22: grrrrrrrrrr

chris22: so you did try to change it to instance.id and it didn't work?

apollo13 I know you don't wan't me to use that script

that didn't work then it gives me None.. but that's explained in the django doc

is there a way to derive a Q instance from a QuerySet instance?

In most cases, this object will not have been saved to the database yet, so if it uses the default AutoField, it might not yet have a value for its primary key field.

this it what the django docs says about instance.id

apollo13: I know Django does not support multiple databases

ok, but then not sure why form.save(commit=false) doesn't solve your problem.

but I don't wan't the id of the model Photos.. I want the id of the user that's currently logged in

christopher22: that doesn't work either? http://dpaste.com/62256/

chris22 right, hence user_id

apollo13: I just want to know if it would be better (performance, wise) if the the chat logs where to be separate from the User profile database

christopher22: that's not related to your user.id problem

in get_image_path() i'm calling on instance.user_id

that's only related to Photo_instance.id in this case

user_id isn't set yet.. that's happends a line later when I use: instance.user = request.user

christopher22: instance.user.id

billy_maze: I wouldn't care for now…

rozwell: forget it, I am trying to tell him this since an hour

rozwell that return DoesNotExists

christopher22: did you try the snippet I just posted?

I'm thinking you need to save the form with commit = false to set the foreign key relationships first

rastem: no

instance.user.id will work

christopher22: i don't see how

if instance.user is valud

christopher22: if we've got a logged in user, then we've certainly got the user's id

rozwell: the error is obscure, but he is using 1.0.2 which had some file problems iirc

your traceback: http://dpaste.com/62257/

about the DoesNotExists

christopher22: Photos() instead of Photo() of course in my paste

it clearly states "DoesNotExists" somehow it's unable to get the user id from the ForeignKey relationship

christopher22: wrong

well I changed everything to Photos()... it just didn't help apollo13

unless you missed to paste the Exception Value

Exception Type: DoesNotExist

christopher22: you get doesnotexist with my paste? then your django install is broken

Exception Value: is empty

or you ran into a 1.0.2 bug

as said, try 1.1

this bug is totally weird. I don't see from the code why this error exists. All I see is the instance.user_id ref needing to be instance.user.id

or instance.user.pk

apollo13, what paste are you now talking about?

rastem: no, if he uses form.save(commit=false) it will fail, no matter what

<apollo13> christopher22: that doesn't work either? http://dpaste.com/62256/

that one

I doubt you will get a DoesnoeExist error

apollo13: just verified, you're correct.

that dpaste doesn't call upon the upload_to path so it never reaches the function get_image_path

2 error in the Django 1.0.2 version?

why 2? that's one ;)

well i'll try to install Django 1.1 Beta

yeah

I just checked with the django source code

how could easily remove django when it's not installed through trunk?

my snippet should work

rm

owkay

chris, or svn the 1.1 beta then symlink the django install in your python path

that way switching back to 1.0.2 is easy as updating symlink

also makes automating this via bash command easy, good for testing.

been trying to get svn working for weeks.. well not svn but the symlink part

not really keen on that part of configuring django with python

christopher22: the django installation docs should describe that

already on that page.. trying the svn co part now

chris: django as a package is linked somehow in your python's site-packages folder. What I find most useful, is to svn co django into a directory with all my other packages

and do an ln -s and set up a symbolic link inside the site-packages to the django folder of the version I downloaded

this also allows me to switch from package to package for testing compatibility and ease of rollback

because changing the symbolic link from going to /home/me/django-trunk/django to /home/me/django-beta-trunk/django is a single command

rastem: that's what virtualenv is for

I am running three version in paralell hear

here*

when i'm using this command: ln -s `pwd`/django-trunk/django SITE-PACKAGES-DIR/django

apollo13: with this custom fields admin widgets - it's not so easy as I thought - is there any doc?

christopher22: http://docs.djangoproject.com/en/dev/topics/ins... refers to creating the symlink

zalun|w: I fear not, just the sourcecode

it says: ln: target `/usr/local/lib/python2.6/site-packages/django' is not a directory

try to force : ln -sf `pwd`/django-trunk/django SITE-PACKAGES-DIR/django

apollo13: I've actually never heard of that, and sounds cool will read up more

apollo13: as it is jumping through many files - I was following the source code and created all fields, but it still renders as the old default

:) well create a formfield and a widget for it and return that in your model.formfield

that should do it

model.formfield should read modelfield.formfield

basically I want to display a thumbnail instead of Currently: uploads/xxx.jpg

ahh :)

there are docs for that

django admin docs

formfield_for_dbfield is the method you want

gn8

so I'm supposing there's no way to save an object into django's session? Perhaps with something akin to Marshal in ruby?

rastem: pickeling?

i see django has a way of generating rss feeds... what if i want to DB a feed?

as in the question here? http://stackoverflow.com/questions/433251/how-d...

Drakonen: true. thoughts on safety / security of storing these objects in session? i.e. I want to store a query object in session, should that be trusted?

and if not, ideas on methods of screening it

why not just store the values?

trying to find a way to save 'state' of a page, just found it easier to save the object with all it's function calls / results / etc already intact

instead of having to do the work twice
