Its the latter. Your query set will loop only for the size of it's length.

Django has a reasonably complete set of transaction control functionality. The official documentation is at: http://docs.djangoproject.com/en/dev/topics/db/transactions/ I also wrote a blog entry about it: http://thebuild.com/blog/2009/11/07/django-postgresql-and-transaction-management/ (The blog entry is with regards to PostgreSQL, but it's pretty generally applicable.)

question about django-pagination
In the django-pagination, it uses the example:
{% autopaginate object_list %}
My question is does object_list have to be the **entire** list over
which I want to paginate, or can I limit the length of object_list? If
I limit the length of object_list, will autopaginate still go through
the entire list?
As an example, say I want to paginate over the list a.field_set.all().
Let's say that list has 1 objects. I might not want my database to
return such a large result set. So I might want to do something like:
object_list = a.field_set()[:5]
Now if I use {% autopaginate object_list %} in my template, would I
still be able to paginate over the entire list of 1 objects? Or my
list would be shortened to 5 objects?

SQL transaction style in django?
Hi, I read that we can overwrite the save() for any model to do something before/after its save. But my issue is, how can I be sure that what i save + what the model needs to save happen as a transaction, so if either fails, the whole thing fails. Example. I want to keep a total inventory count in a model called "Item". I want to then be able to add entries in model ItemEntry, which has a count_used. When the ItemEntry model is being saved, I want to deduct the amount from the total in corresponding "Item" model. But if I do something like: # forgive the syntax, I'm winging it right now class ItemEntry(models.Model): def save(): i = Item.objects.get(pk=5) i.count = i.count - used_value i.save() self.save() if either fails in the "save()", the data will be out of sync. Is there a way to wrap this in a "transaction", without going into the database itself and creating triggers, etc.? Can I specify trigger like behaviour in the model definition? I would like to not have changes in some other place(e.g. DB), since django's advantage is centrally organizing things.

To be perfectly honest, I stopped caring about man-in-the-middle and eavesdropping attacks a very long time ago. I suppose that if I were employed by a defense or intelligence agency, or if I were handling extremely sensitive corporate or financial data, I might give some thought to them, because the security requirements in those fields are so strict and the stakes are so high (US defense/intelligence agencies, for example, go so far as to mandate specific -- classified -- RF-emission requirements for their hardware, in order to prevent electromagnetic eavesdropping). Even in that situation, though, MITM would not be atop my list of priorities. And the plain and simple truth is that I don't work in such fields. I write software to let news companies publish things, and MITM really isn't even on my radar. If this seems strange, consider that an attacker -- should he or she be both motivated and determined enough to try to obtain the credentials of one of my users -- simply has access to far too many easier and simpler attack vectors which can accomplish that. First on the list, and hardest to defend, is phishing: it doesn't matter how much security I build in to the connection between my server and my user's browser, if the user can be fooled into typing credentials into a form on some other site. And fooling users into doing that is unbelievably easy. Then there are the cross-site scripting and cross-site request forgery attacks, both of which can be pulled off easily and in ways which are hard to detect. XSS is the ring-0 attack of the web, and a far more likely vector than packet sniffing or cookie replaying. And CSRF is the terrorist hijack of the Internet, but you don't realize you've been hijacked until it's far too late. At least they can be mitigated and prevented, and Django provides tools which allow you to do just that. But there's a whole list of easy but effective tactics which goes on and on; most involve social engineering or low-tech methods. Some are as simple as glancing over someone's shoulder in a coffeeshop. And all of them are far, far, far more likely to be used against you than a frail and complex credential-sniffing man-in-the-middle attack. Like I said, MITM just isn't even on my radar, and probably shouldn't be on yours either. But if you feel you must focus on unlikely and difficult threat models rather than likely and simple ones, there's an easy answer: HTTPS for everything. Nothing else comes close, and probably nothing else will for the foreseeable future. Of course, this presumes that your users know how to spot the difference between plain unencrypted HTTP and encrypted HTTPS, or are paying attention to the indicators their browsers give about certificate validity, or are even bothering to look at the address bar at all. Sadly, the answer to all of those questions is "no": your users don't know and don't care, and if someone decides it's worth going after them, they'll get compromised by far simpler, far lower-tech phishing attacks just like everybody else... -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." -- You received this message because you are subscribed to the Google Groups "Django users" group.

Rails-style form value deserializer?
One thing I'm keenly missing from rails is the form input naming convention
that causes the form values to be converted into a hierarchy. For instance,
will result in the request values being stored as { 'foo' : {'bar' : 'one',
'baz' : 'two' }}
this is very handy when updating multiple related objects in a single form
submit.
Is there a similar facility for django/python or will I need to write it?

attachments vs filebrowser
I need users to attach arbitrary media files to database records. Attachments seems to do what I need, except that its UI is utterly lame - it should figure out the media type of the file from the extension and display an appropriate thumbnail as well as a way to provide a viewer inline. Also, it relies on a bunch of custom tags for django's template processor but I'm using jinja2. filebrowser seems smarter this way, but seems targeted strictly at trusted users. I need arbitrary users to be able to attach files. Is there something else I ought to consider? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Problem with Meta inner class accessing its parent
Thanks for the information, I will look into your suggestions. The
getLanguage design did seem to work though, as changing the language
did have an effect on the __unicode__ function: in the admin interface
the correct values (for that language) were shown. At least it did so
on the local runserver environment. I can see though that even though
__unicode__ is called every time, the ordering is probably called only
at import time, and my little plan won't work.
Have to find a solution for that problem first I guess, before I even
start to tackle the problem of how to set the ordering...

Correct way to unlazify a SimpleLazyObject?
I recently got burned by r11626, which added SimpleLazyObject to
1.1.x. I have a templatetag that linkifies a user-object, and it
checks whether it is given a django.contrib.auth.models.User, an int
(looks up a User) or a profile (looks up the User). This check was
done with type(). Unfortunately, type(SimpleLazyObject) !=
type(User()), so I had a "fun" TemplateSyntaxError in my hands.
However, the TemplateSyntaxError never happened if there was an
instance of {{ user }} before the {% prettylinktouser user %} in the
template, thus it seems to me that just outputting a SimpleLazyObject
somehow unlazifies it. So, how can a SimpleLazyObject be unlazified
everywhere else?

Yes - {{ field }}

Custom Model Field with Validation...how to hook it back to ModelForm
Hello...
A common occurrence I have with one particular project is that it
requires the user to enter dimensions (for width/depth/height) in Feet
and Inches. Calculations are needed to be performed on that dimension,
so I've been working on a custom field type that takes in a dimension
in Feet/Inches (eg. 1'-10") and saves it to the database as a decimal
number using a regex to parse the input. The field displays to the end-
user as feet-inches at all times (with the eventual goal of writing a
method to be able to optionally display in metric, and interact with
measure.py, and geodjango stuff). What I have so far is definitely not
DRY, but aside from that, I'm having trouble with validation at the
form level. The custom model field itself works properly (from what
I've seen), and I've written a form field clean method which should
work to validate the field. My question is how to hook that form field
back into my model form to work for all the width/depth/height fields.
I'm thinking maybe an override of the init on the modelform (a la
self.fields['depth']...) , but I'm not quite sure where to go from
here...would you help me?

Having trouble building a search form with proper filters
Okay, Here's a quick look at my model layout Contact : company -> ForeignKey -> Company Company : type --> OneToOne --> Type Type : type (character) I'm trying to build a search that will return contacts based on certain criteria. Any other fields in Company that do not join to another table work just fine (e.g. company__city__icontains=city). But, any way I've tried to filter based on the type (e.g. company__type__type__icontans=type) results in failure. (I've tried all I can think of, but cannot find a solution). Failure (in this case) is : Join on field 'type' not permitted. Any ideas would be greatly appreciated!!!

Learning Django - Error going through Chapt 4 on Templates at DjangoBook.com - Probably real simple
I am brand new to Django and I'm trying to get up to speed ASAP. I
really like it so far. I'm getting an error trying to create a
template in the shell.
>>> from django import template
>>> t = template.Template('My name is {{ name }}.')

I am using Ubuntu (Karmic Koala) and I installed from the Package

problem.
Can anyone give me a quick fix/explanation? I'd rather not skip this
issue because I imagine it will come back to bite me later.

It seems Chrome beta doesn't like something about the delivery of the tar.gz. When I used IE, the file opened first try.

YMMV but I don't like modules growing much bigger than 1 to > 1.5 KLOC. In general I agree that many small files are nice. And in the case of view.py, forms.py, etc., django doesn't know about those names specially. view files are referred to in your url.py, which itself is just referred to in your root url.py, which is referred to in your settings.py, so all their names can change without any problem, other than making your code harder for someone else to maintain. But the name models is known specially by the framework. All in all, I don't care much how many lines there are in a models.py file. After all, I don't use notepad, with its 64kib limit, to edit python code. I *do* care how many lines there are in a class, since that is the unit that I must understand. Moving those classes into separate files doesn't make them smaller. I do, also, prefer small apps. When I needed to rework the (pinax) profile app, I was happy to only have to copy that to change, rather than having to include django.contrib.auth, account, emailconfirmation, and who knows what else has a close relationship with django.contrib.auth. So I don't care how many models are in a module, but I think that five is about as many as I would want in an app. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Problem with Meta inner class accessing its parent
I can't promise that it will do what you want, but your problem is
that at the time
you try to set the value of Meta.ordering, class Substrate does not yet exist.
You can dig into the Substrate.objects._meta later to add ordering, probably.
Your design wouldn't have worked anyway, since getLanguage would only
have been called once, at import time, and even if that worked, it wouldn't
follow current language as it changes (I presume) from request to request.
Oh, and since you're not calling getLanguage on a class instance, it would
have to be declared a staticmethod or classmethod, and not get the self
argument or replace it with cls (for classmethod). Static method would be
the choice here (and no self)
It's mildly possible that ordering is allowed to be a callable. If
so, you could
assign it to a function (not a method of the not yet defined Substrate). That's
the function itself, no parentheses. The function would return the list.
If ordering can't be a callable, you could create a class that implements enough
of list behavior to satisfy the framework (a subject for research or
experimentation,
but iteration might be enough) and set ordering to an instance, whose apparent
content depends on the current language.
It still might not work, if the __metaclass__ processes Meta.ordering at clas
definition time. You have the source code.

You will need to add one of the LDAP backends to this setting. The eDirectory backend is pretty generic, and will be a better bet than the ActiveDirectory backend. That's not the problem you are having, but is something you'll need to handle shortly. > > The error message came from command: python manage.py syncdb > Creating table ldap_groups_ldapgroup > Traceback (most recent call last): > [snip] > cx_Oracle.DatabaseError: ORA-02329: column of datatype LOB cannot be > unique or a > primary key > In ldap_groups/models.py, the LDAPGroup.org_unit field is a TextField, and is marked unique=True. I'm thinking that the cx_Oracle backend is translating the TextField into a Large Object (LOB) field in Oracle, and Oracle cannot ensure uniqueness of a Large Object. In short, remove the "unique=True" from the ldap-groups code and try again. It should work after that. This error arises from an inconsistency between the behavior of Oracle and the behavior of PostgreSQL, as Mike noted. It works under Postgres. I'll check with the dev list and see if this behavior difference is known, and whether the fix is to never use unique=True on a TextField (a bug in my code), or something that needs to be smoothed over in the SQL generation for Oracle specifically (a bug in the underlying Django behavior). Let me know if you have further questions, I'm happy to assist. Regards, ---Peter Herndon -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Strange problem when starting project in Windows XP
What happens when you type 'python django-admin.py'? If that doesn't work, try replacing 'python' there with the full path to your Python executable in Windows. I've never heard of this problem, but it sounds like it could be something odd in the environment.

Strange problem when starting project in Windows XP
Hi all, I'm new to Django. I got through the beginner tutorial without much trouble and I just finished the introductory chapters of The Definitive Guide, so I decided to start work on a real project. I've quickly run into a bizarre stumbling block however when I try to start my new project. I run cmd.exe to open the windows command prompt, then I navigate to my django projects folder, then type 'django-admin.py startproject newsite' and then I get this error in the command prompt: 'The system cannot find the file idle.pyw'. I also get an error dialog in windows titled 'idle.pyw' that says 'Windows cannot find 'idle.pyw'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.' I get the same error if I simply type 'django-admin.py' into the prompt as well. I really have no clue what's going on here. What does idle.pyw have to do with anything? Google has been no help. I did this exact same thing when going through the tutorial with no problems whatsoever, and made no changes to any of my PATH variables or anything of that kind. Any ideas? I'm really eager to get going with Django but feeling quite frustrated! Thanks for help. -Dane -- You received this message because you are subscribed to the Google Groups "Django users" group.

Problem with Meta inner class accessing its parent
Hi,
I am having a bit of a problem. I have a model with 3 name fields,
each for a different language. By creating an __unicode__ function
like below, I always get the correct name for the current language.
Works fine.
But, I want to change the default ordering for this model, so that in
each language, the correct order is used. Sadly, this doesn't work, as
I get the error "NameError: name 'Substrate' is not defined". Also
"self" and "super" don't seem to work. I just can't seem to be able to
access the parent class from within the Meta class.
I can't even repeat the getLanguage function into the Meta class,
because then I get an the error "TypeError: 'class Meta' got invalid
attribute(s): getLanguage".
class Substrate(models.Model):
name_en = models.CharField(max_length=255)
name_de = models.CharField(max_length=255, blank=True)
name_nl = models.CharField(max_length=255, blank=True)
def getLanguage(self):
from django.utils import translation
current_language = translation.get_language()
if not current_language:
current_language = 'en'
return current_language
def getName(self):
current_language = self.getLanguage()
name = getattr(self, 'name_'+current_language, self.name_en)
if not name:
name = self.name_en
return name
def __unicode__(self):
return self.getName()
class Meta:
ordering = [('name_%s' % Substrate.getLanguage()), 'name_en']
If anyone has an idea how on to do this, I would be very happy.
Thanks!
Cheers,
Kevin

format date output in mail form
I saw a solution on the list to format a datefield in a template.
Unfortunately i didnt find any solution for formatting a datefield in
a mailform. I have this in my model:
Aankomst = forms.DateField(('%d/%m/%Y',), widget=forms.DateTimeInput
(format='%d/%m/%Y', attrs={
'class':'formVeld',
'readonly':'readonly',
'size':'8'
}), required=False)
This is a part of my view:
Aankomst = form.cleaned_data['Aankomst']
aankomst = str(Aankomst)
message = aankomst
The date output in my mail is:
2010-07-30
I would like it to have it as: 03/07/2010 Is there a solution for this?

The Python equivalent of null is None - if you explicitly need to
check for that value, that's how you should spell it.
However normally the better way of doing it is just
{% if field %}
etc, since None is boolean false, as is False, 0 and [].

Re: InternalError -- django specific state?
In fact, my code had a bug in it -- I was both rolling back and releasing the savepoint (via a finally). Sorry about that. For the record this *does* work: you can use savepoints and row-level locking for synchronization between different processes, as you would hope Thanks.
