akahn0889: Just custom labels for True and False. It needs to be a boolean because it's a boolean semantically.

jonash: Have you tried setting the labels in your form's attributes dictionary or something like that?

so I have a Person model with a groups many-to-many field. I'm trying to do a query like Person.objects.filter(groups=mygroups), where mygroups can be either None, or having some group ids. Problem is this doesn't work if mygroups is None, where i'd like to basically ignore and return all Persons

I can easily write an if statement and make it a different query, but was wondering if there's a better way in the same query

jonash: That way you're just keeping it a UI thing, not an internal necessity

leonsas: Do the if check. They're not the same query, after all.

leonsas: try using ' __in = mygroups'in your query

Right yeah, I know the __in

but it seems like it'd be a similar query

except the None case should include all instead

Of course doing the check is trivial, but the query is not exactly a one liner, and this check would just make it uglier

Well, querysets are lazy.

leonsas: You might want to use a Q object and throw an | in there.

Yeah, I'd probably use Q

So, qs = Person.objects.all() ; if mygroups: qs = qs.filter(groups=mygroups)

akahn0889: I haven't but I wonder why it doesn't work if I set it in the model layer

Hi, i want make a view to add elements to a m2m relathionship, i want be able to add 5 at same tame so i think i need to use modelformset_factory, right now my formset display correctly the 5 elements, other think what i want to do is change the queryset for exclude one option but i am not be able to do it: https://dpaste.de/GJWb#L64,65,66,67

jonash: Well, it depends on the form you are using. That is, validation and defaults can give you funky stuff.

marsje: solved your problem?

akahn0889: mmmm... funky stuff... I mean it shouldn't surprise me. And in this case it could even lead to bugs since it's now possible to submit the form without supplying any value

akahn0889: OK, just had a look at the implementation. They're setting blank=True in the field's __init__. I think this should be skipped if 'choices' is given.

jonash: I would avoid messing with the __init__ method, maybe override the default widget? If it's just labels you want to change, just set the field's label.

mstrcnvs: looks like it....

mstrcnvs: I added a WSGIPythonPath directive pointing to my django project and that seems to work

yes, you need to point it to your virtualenv and your project path

mstrcnvs: I also tried adding the same directory to the python-path parameter of WSGIDaemonProcess, but that didn't work

akahn0889: I see how to solve this, yeah. I still think it's a bug

mstrcnvs: I'm not using virtual-env

yeah, this settings are really confusing

when to use WSGIPythonPath or python-path

but if it works, then, just accept it :p

mstrcnvs: it sounds the same to me... but you can only have one WSGIPythonPath for all your virtual servers it seems

don't think so

then you can have just one django instance running?

mstrcnvs: if I use it within the virtual server, it fails

jonash: I'm not learned enough on django internals to know but you can file it.

mstrcnvs: no, but you have to specify all paths to that one directive I guess

hi, what's the correct way to create teh superuser password noninteractively?

User.set_password

Maior: you there?

mstrcnvs: sup?

(only vaguely; middle of a game of DotA...)

Maior: where are your company located in London?

mstrcnvs: Moorgate (Cityish)

not close to Paddington right?

other side

so no visit from your fellow here :'(

wait, is not that far

only 30 min with subway

Hello, can someone help me with a query? I have some models, Profile, ProfileItem, Item, and Criteria, where ProfileItem is a through table for the Profile and Item ManyToMany relationship, and where Criteria has OneToMany(Item). I would like to Find all Criteria relevant to Profile, but filtering on a field in ProfileItem.

Ie. Profile.items.criteria_set().filter(ProfileItems__gt=0)

But, I'm not sure how to access that profileitems field while going through the 'items' related_name

__

mstrcnvs: also depending on date/time I can head there

Maior: I will stay 5 days in london, let's see if I get some time to visit your company, would that be a problem for you?

mstrcnvs: not at all, but since our presence in London is "me", lets just go for coffee? :P

sure
