displaying a foreign key in admin list and template exception
Hi all,
I'm having some problems and I've isolated them in a small example. I
have the following data model:
class Currency(meta.Model):
name = meta.CharField(maxlength=5)
def __repr__(self):
return self.name
class META:
admin = meta.Admin()
class CustomData(meta.Model):
amount = meta.IntegerField()
loan = meta.IntegerField()
currency = meta.ForeignKey(Currency, to_field='name')
def __repr__(self):
return self.amount
class META:
admin = meta.Admin(
list_display = ('amount', 'loan', 'currency'),
)
Now, addinga a currency works fine. Trying to add a customdata, when
saving, yelds a template exception. I've read on this group that this
might be because something's wrong in the model. Any ideas?
The other problem is that with the current list_display in CustomData,
there is no listing of the items. Just "3 custom datas". Once I remove
'currency' from list_display, I get them listed ok. This is driving me
mad. I'm probably doing something wrong, but I can't figure out what.
Thanks,
Andu

Hi Andrew,
This isn't a bug -- it's intended behavior. When you access an element
in a MultiValueDict, it returns the last item, as a string. See the
docs for more info:
http://www.djangoproject.com/documentation/request_response/#querydict-objects
If you want to get a list instead of a string, use
data.getlist('costs') instead of data['costs'].

iterator lookup function crashs
Hi all,
i'm trying to use the iterator lookup function on my model, but it
failed.
My model is the following :
from django.core import meta
STATUS_CHOICES = (
(0, 'Added'),
(1, 'Requested'),
(2, 'Registered'),
)
# Create your models here.
class User(meta.Model):
msisdn = meta.CharField(maxlength=12, db_index=True, unique=True)
first_name = meta.CharField(maxlength=30)
last_name = meta.CharField(maxlength=30)
class META:
admin = meta.Admin()
def __repr__(self):
return "%s %s" % (self.first_name, self.last_name)
def _pre_save(self):
self.first_name = self.first_name.capitalize()
self.last_name = self.last_name.capitalize()
self.msisdn = self.msisdn.replace(' ', '')
self.msisdn = self.msisdn.replace('.', '')
class User_Extended(meta.Model):
user = meta.ForeignKey(User)
user_agent = meta.CharField(maxlength=255, core=True)
class META:
admin = meta.Admin()
verbose_name_plural = 'users_extended'
module_name = 'users_extended'
class Event(meta.Model):
name = meta.SlugField()
repr_date = meta.DateTimeField(verbose_name="representation date")
class META:
admin = meta.Admin()
def __repr__(self):
return self.name
class Member(meta.Model):
user = meta.ForeignKey(User)
event = meta.ForeignKey(Event)
status = meta.IntegerField(choices=STATUS_CHOICES)
class META:
admin = meta.Admin()
def __repr__(self):
return "%r (%r)" % (self.get_user(), self.get_event())
And i try to do the following :
>>> from django.models.flood import members
>>> e = events.get_values(pk=1)
>>> for m in members.get_iterator(event__exact=e):
... print m
The following error is raised :

What's wrong with my code ? (I've got the last SVN version of Django,

Many thanks in advance.

The easiest way to iterate through and find a loop during the save()
call of the object. (Using _pre_save() for pre-magic-removal code.)
An example is provided in this cookbook entry:

is_member_of method for user objects
Hello,
I wasn't able to find an easy way to check if a user is a member of a
group, so I added the method; here is a patch for:
django/django/models/auth.py
Index: auth.py
===
--- auth.py (revision 2296)
+++ auth.py (working copy)
@@ -142,6 +142,12 @@
self._perm_cache.update(self.get_group_permissions())

+return False
+
def has_perm(self, perm):
"Returns True if the user has the specified permission."
if not self.is_active:
Hers is some quick usage:
from django.models.auth import users
u = users.get_object(pk=1)
if u.is_member_of('super_group'):
print 'yay!'
Would it be possible for me to use this function within a template, for example:
{% if user.is_member_of:"blah" %}
The above, of course, does not work.
Thanks!
