what would be the best way to extract the id field from a queryset into the format [1, 2, 4, 5] ?

values_list

hi - i'm looking for tip on using inline ManyToMany fields in the admin interface. I've got a Task model that can be assigned to a User in the admin. I'd like the selection of Users available in the admin UI to be a subset of all the Users of the website. Any suggestions on how that might be done? Many thanks in advance...

mattmcc: thanks muchly. i'm having trouble finding my way through the documentation tonight... i've been up working, in meetings, etc for 16 hours :S

mile1 I dunno, I recently tried that, using the limit_choices_to parameter when defining the M2M, but it didn't have any affect. I'm not sure if I did something wrong, or if it's broken.

anyone know what this is ? http://dpaste.com/72561/

something about bad magic number in newforms

shivraj hm, sounds like your pyc file may be corrupted somehow. Remove /usr/lib/python2.5/site-packages/django/newforms/__init__.pyc and try again.

shivraj - i ran into the same problem & solved it by removing the pyc files, which were out of date

i suspect it had something to do with me switching back and forth between nfa and pre-nfa

</random>

ok cause its saying something else ... let me remove all of the .pyc

Zalamander - thanks. i'm not familiar with limit_choices_to_parameter. i'll need to check that out (though if it didn't work for you....)

that's a lot of pyc's :-)

yep :-)

mile1 yeah, I tried limit_choices_to={'is_superuser':(False,)} maybe I need to use 0 instead of False

Zalamander : where ?

I onlyremoved the ones in newforms

shivraj where what?

nwo I get this error http://dpaste.com/72563/

which .pyc files do I remove ?

shivraj it looks like you got all the bad ones.

Zalamander - i think you're on to something. using limit_choices_to={'username': 'mynamehere'} worked as expected

/join #debianeee

now to try the group filtering....

limit_choices_to cannot be dynamic though

oops..

mile1 eh, good to know, lemme see if my boolean change works

if I have two models, joined by a OneToOneField, and I delete one of them-- will the delete cascade to the other?

only if you delete the one without the 1-1 field

Magus - thanks for the tip

any other ideas/approaches?

i'd like to filter by group membership

Magus-: is this a general rule of thumb-- that deleting the object lacking the relation field cascades to the one with the field?

mile1: I have no solution for you

I just know that option won't work

mile1 : I have to delete all .pyc files in django ??

ok - thanks anyway

~.

t3mp3st: yes, that's how cascading works

it doesn't go the other way

the cascade is because you would otherwise have a hanging relationship

like fkey_id = 3, but id = 3 is deleted

but if you delete the one /with/ the relationship, nothing is left hanging

okay, that certainly makes sense :P

mile1 ah, I got it, I needed to use False, not (False,). I was too caught up in mimicing the example, which uses a containment test.

thanks Magus-, as always!

I think I should remove Django and reinstall a new copy

shivraj - yes - i used the find command

shivraj: you do actually have that view mapped as a url, yes?

Magus- : which one ? registration_complete ?

no, one that isn't erroring...

x.x

of course that one :þ

heh

we're looking for a url name of that btw, not a view name

well its in accounts/

but does it actually have that name?

Zalamander - good to know - i'll watch out for that

yeah, beware stupidity :-)

let me check, I installed the other apps it was complaining abt reverse for

return HttpResponseRedirect(success_url or reverse('registration_complete'))

so I have to put success_url in urls.py ? or where exactly should this registration_complete view go ?

will it go to the first url with a registration_complete view in it ?
