Re: How to select all the values from my Field attribute 'choices?
How can I get all values of my "choices"? I have a template which contains an drop-down-list with all values. The drop-down-list has several entries but unfortunatelly only the same. In my choices- list I have 5 entries. And in the drop-down-list 5 entries, too (But the same). How can I get all values? From a table it's easy: Just type "nations = Country.objects.all()" With a choice-list "objects.all()" doesn't work. äL On 8 Nov., 13:42, "Marty Alchin" <[EMAIL PROTECTED]> wrote: > On 11/8/07, äL <[EMAIL PROTECTED]> wrote: > > > Do I have an error in the import syntax?

Re: How to select all the values from my Field attribute 'choices?
Hi,
If I try to import ROLE I get an the error "cannot import name ROLE"
views.py
### CODE ###
def Karateka_edit(request, karateka_id):
from kav.info.models import Karateka, ROLE
roles= [y for x,y in ROLE]
try:
karateka = Karateka.objects.get(id = karateka_id)
except Karateka.DoesNotExist:
raise Http404
return render_to_response('info_karateka_edit.html', {
'karateka' : karateka,
'roles' : roles,
'user' : request.user})
### END CODE ###
Here is my models.py
### CODE ###
class Karateka(models.Model):
ROLE = (
('1', 'Sportler'),
('2', 'Nachwuchsteam A'),
('3', 'Nachwuchsteam B'),
('4', 'Funktionär'),
('5', 'Trainer'),
)
person= models.ForeignKey (Person,verbose_name = 'Person',
core = True)
role = models.CharField('Funktion',blank = True, null =
True, maxlength = 1, choices=ROLE)
def __str__(self):
return "%s" % (self.person)
class Admin:
list_display = ('person')
fields = (
(None, {'fields': ('person', 'bsc')}),
)
def name_last(self):
return "%s" % (self.person.nameLast)
class Meta:
ordering = ('person',)
verbose_name= 'Karateka'
verbose_name_plural = 'Karatekas'
### END CODE ###
Do I have an error in the import syntax? How can I import ROLE?
Thanks for your help
regards,
äL

Yes, assuming ROLE is defined in your models file you will need to import it
when you want to use it from another file. But that is not why you got a
404 (page not found). Given that code, you'd only get a 404 if the
Karateka.objects.get call raises Karateka.DoesNotExist. So you didn't even
get as far as the roles= line (there's no reason to include that in the
try/except btw). If you had gotten as far as the roles= line and if you had
not imported ROLE from wherever it is defined, you would have gotten a
NameError "Global name ROLE is not defined".

Re: How to select all the values from my Field attribute 'choices?
Hello Karen
I have the same problem as Greg has.
If I try to use your code I got an "page not found" error.
Here is my code:
views.py
### CODE ###
def Karateka_edit(request, karateka_id):
from kav.info.models import Karateka
try:
karateka = Karateka.objects.get(id = karateka_id)
roles= [y for x,y in ROLE]
except Karateka.DoesNotExist:
raise Http404
return render_to_response('info_karateka_edit.html', {
'karateka' : karateka,
'roles' : roles,
'user' : request.user})
### END CODE ###
Do I need to import ROLE like Karateka or do I have an other error in
my code?
Regards,
äL

Well, you can't set up a query for something that isn't in the database.
But the values are right there in THE_MATERIAL. If you want a list of just
the text values, stripping away the numeric choices, some simple Python:
material_list = [y for x,y in THE_MATERIAL]
would do it.

How to select all the values from my Field attribute 'choices?
Hello,
When I first developed my application I created a table that stored
all the different types of materials
class Material(models.Model):
material = models.CharField(maxlength=100)
To get all the materials in the table all I needed to do was query the
table. Recently, I've been going through my code to see if I can
clean it up. So I deleted my table Material and made it into a
'choices' attribute. So now I have
class Collection(models.Model):
THE_MATERIAL = (
('1', 'Paper'),('2', 'Plastic'),('3', 'Other'),
)
material = models.CharField(max_length=50, choices=THE_MATERIAL)
///
However, now I want to be able to do a query that returns all of the
values in THE_MATERIAL (even if it's not being used by any
collection). How would the query be setup to do this?
Thanks
