Templaite:display li items alternatively using for
Hi,
I want to display a list of items by using {% for item in items %}.
To make the web pages look better, I want to use two kinds of
alternatively.
E.G item
item
My question is how can i use the tags to implement this requirement?
Any build-in tags for this?
Thanks in advance,

There's nothing built into Django that does this.

If you look in django.contrib, there are several applications which instruct you to fill in a setting which exists only for purposes of that application.

alert table while updating model automatically
Hi All, I want to know whether Django support alerting the tables automatically while I modify the models or not. Suppose the website has run a long time and stored lots of data. In this case, the administrator wants to modify the model to add/remove some properties. Does the corresponding tables in the database will be alerted automatically? If not, how can make it happen?

Re: Using settings.py mechanism for application settings
I'm a little confused as to the purpose behind the question, it feels pretty general, so I have a few questions. 1. When you say application are you talking about django apps generated via the "manage.py startapp" command? 2. LazySettings allows for a "proxying" of the Global settings in your projectsname.settings. So I'm wondering if you're talking about in each "application" from (1.), that you'd have a "local" settings? 3. Refactoring for portability? as per my understanding "refactoring" means to rewrite better or to improve upon a code block/segment/file whatever, are you talking about the ability to copy paste an "app"(1.) into another django project created via django-admin.py so that it maintains it's own ability to have a local configuration that is universal regardless of what django project it sits in?

Re: Is there a way to use the Cut Filter to only do the first instance?
If you know the length of the string that you want to cut off the
beginning, you could use slice:
http://docs.djangoproject.com/en/dev/ref/templates/builtins/#slice
Really, though, you might be going about this in a strange way. It
might be better to use the url tag to get the correct URL that you
want in the first place. But then, I don't know what you're trying to
do.

Using settings.py mechanism for application settings
There are always needs for application level configuration settings. I really like the way settings.py works, with a package (django) level default settings overridable by local settings.

Yes, mod_wsgi will by default run different WSGI applications within a
VirtualHost in different sub interpreters of same process. It has the
added benefit though that you could also delegate each application in
same virtual host to different daemon process groups. That or even mix
and match them, having some delegated out to separate process at the
same time as keeping some running in the Apache child processes.
In mod_python, the default is to run all applications within a
VirtualHost (regardless of listener port), in the same sub
interpreter. For Django, because DJANGO_SETTINGS_MODULE global, this
will not work. For mod_python you need to use PythonInterpreter
directive and manually designate that applications should run in
different sub interpreters.
Thus, mod_wsgi is far more flexible than mod_python in this respect.

Hmmm, seems you basically asked the same question twice. See: http://groups.google.com/group/django-users/browse_frm/thread/dda2008ccbc8cd65 If you are getting empty input on read, then you are using hosting mechanism that doesn't properly filter out chunked request content as not being supported and instead assumes that content length of request was 0.

I think me memory is okay. Comments in event MPM code say: * This MPM tries to fix the 'keep alive problem' in HTTP. * * After a client completes the first request, the client can keep the * connection open to send more requests with the same socket. This can save * signifigant overhead in creating TCP connections. However, the major * disadvantage is that Apache traditionally keeps an entire child * process/thread waiting for data from the client. To solve this problem, * this MPM has a dedicated thread for handling both the Listenting sockets, * and all sockets that are in a Keep Alive status. and looking at code it does indeed seem to send accept socket direct into worker thread queue for processing before any data actually read.

Thus, holding the Apache process for less amount of time. I'll look into > this in more detail once I have the Apache setup working as I like. Yes, in theory that as well. This is where one would have thought the Apache event MPM might help, but from what I remember at look at code, the special event worker thread only deals with accepting the new connection (before handing it off to another thread) and later perhaps (can't remember) dealing with management of keep alive connections. In other words, don't believe the Apache event MPM uses the event worker thread to at least read in the HTTP request header before handing it off to another thread for processing. Thus, request has already been handed off to its own thread for that part of the request which may arrive slow, ie., the HTTP request information. I will need to check again though if what I remember is correct. :-) This is where nginx is better, as the event model can handle all that HTTP request header reading in single thread by multiplexing it based on availability of data. Therefore you don't suffer the Apache overhead of memory usage for threads sitting there waiting for slow data to come for HTTP request header. Anyway, before you quote me on how Apache event MPM works, I better go check.

What hosting mechanism are you using. Anything that uses WSGI (eg, mod_wsgi, fastcgi/flup) or mod_python will not work as neither WSGI specification or mod_python support chunked transfer encoding on request content.

HttpRequest with chunked encoding is not buffered
Hello, I'm trying to receive a possibly large XML message via HttpRequest (POST method) with chunked encoding. However, when I send a response, I found out (using Wireshark) that the response is being sent before the whole POST request body is available. I expected Django to be buffering the chunks and that the request would be complete, but that's apparently not happening...

and in an admin.py file I have:
class ImageAdmin(admin.ModelAdmin):

filter_horizontal = ('portfolios',)
admin.site.register(Image, ImageAdmin)
This works fine even after upgrading to 1.0. But when I follow the new
docs and change my Image model's many-to-many definition to:
portfolios = models.ManyToManyField(Portfolio, through="ImagePort",
blank=True)
I lose the many-to-many portfolios with the nifty filter_horizontal in
the Image admin. I can get the admin.TabularInline interface by
following the docs, but like most people I really prefer the nifty
javascript version. If I try to add the portfolio with something like
fields=('portfolios',) in the ImageAdmin I get a template syntax error
complaining that the key 'portfolio' is not found.
Am I doing something obviously wrong?

Response is sent before post body arrives
Hi, I'm using chunked transfer encoding and i send a post http request to my Django application. But when I try to read the post body, it's not there (request.POST.keys() returns []). according to Wireshark, I send the response and right after that comes the request body. Do you know how to wait till the body arrives? And why does Django not wait for it automatically?

Using Django
Hello, I'm new to Django and it's taken me a while to get things setup correctly on Dreamhost. I've done the tutorials on my local machine prior to setting things up on Dreamhost but it seems like I'm missing instructions on how to actually use Django. Yes, I've read the "Using Django" section of the website but I don't even know how/where my pages should reside. If I request http://www.mysite.com, how do I route that to my "projects" directory where the "mysite" directory resides, a symbolic link? - which I tried but just returns a 403 error. I'm still used to the traditional "mysite.com" directory which contains index.php, contact.php, etc., and I don't understand how the directory structure for Django works. It seems like the tutorials just show you how to start a project under test conditions and show off the built-in admin tools, without really explaining how things are setup for an actual website. Maybe this system is over my head... Thanks, Jason --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Indeed both these options sound useful. I already use MaxRequestsPerChild for Apache, but having the same for the Python daemon process makes sense. The inactivity-timeout will be useful since I have cronjobs that run during low traffic hours to do random work and will benefit from more available memory.

Yep, Keep-Alive off makes a decent difference when I'm benchmarking a single dynamic script with some concurrency (and the benchmarking client is explicitly not reusing connections). And since I dont have many (any?) cases of immediate follow up requests, Keep-Alive is not very useful for now.

PHP is indeed why you're seeing this here - but finally once I'm done with my current migration, the last PHP site will be gone. I was planning on switching to worker, but just yesterday realized that my distro only comes with the prefork mpm.

Re: How to setup django-apache-mod_wsgi without killing existing php site?
I run prefork with mod_wsgi (embedded) and mod_php. No troubles so far, though I'm using MySQL with PHP and Postgres with Django, so I'm not likely to experience the MySQL library issues Graham described. I've read that mod_php actually doesn't like worker MPM, because come common PHP extensions aren't thread safe. My setup is for a general development environment... low traffic. For something more robust I would dedicate a server to Django and run mod_wsgi with worker MPM. That seems to be the fastest setup, from everything I've _read_ (no experience with worker). Of course, proxy to Apache via nginx or alternative. Ross --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Are you using mod_wsgi, mod_python or what?
If you're using mod_wsgi: From what I gather, running multiple django
projects under the same VirtualHost currently has things to deal with
to get it working. (See
http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango
-- search for "Note that Django expects").

thanks I'll try subprocess and jython but I have heard that django

Re: Is there a way to host serveral django projects under a single virtual host
Of course there is :), for the VirtualHost *, means everything, instead
use names like projecta, projectb, etc...if that doesn't make sense then
the best thing to do prior to messing with your settings is to read the
documentation from apache on VirtualHost.

updating a single field / attribute, is it possible? or better practices?
Hi all,
Is it possible to update a chosen subset of attributes of a model
instance?
In my case, the view function saves a model instance which was updated
in the model's custom save() method. Thus, the update by the save() is
overridden.
Pseudo code of the scenario:
class MyModel(Model):
qualified = models.BooleanField()
count = models.IntegerField()
def save(self):
self.count = self.refmodel_set.count(qualified=True)
super(...).save()
class RefModel(Model):
my_model = models.ForeignKey(MyModel)
def form_view(request, id):
my_instance = MyModel.objects.get(id=id)
ref_form = RefForm(data)
if ref_form.is_valid():
ref = ref_form.save(commit=False)
ref.my_model = my_instance
ref.save()
if ref.some_attribute:
my_instance.qualified = True
my_instance.save() # this overrides the change made in
MyModel.save()
I thought, if there is a way to save only a single attribute, without
touching others, my problem will be solved. In that case, the last two
lines would look like:
my_instance.qualified = True
my_instance.save(fields=('qualified',))
Does this makes sense?
Thanks for any comments,
oMat

No, there's no way to make the existing cut filter do this, and I don't see
another built-in filter that does what you ask. However if you look at the
implementation of cut here:
http://code.djangoproject.com/browser/django/tags/releases/1.0/django/template/defaultfilters.py#L325
and the doc for Python's string replace method you can pretty easily write
your own cut_first filter.

ServerAlias *.projects
RewriteEngine on

In order to sort by something not in the database, Django would need to retrieve all rows, do the sort (calling your callable for each row in the DB), and then limit the result according to the page you are viewing.

browser setting takes over /i18n/setlang?language=english
Hello, I'm checking out the i18N features and apparently the browser setting takes over always, if I try to select the language via the link it doesn't work, it just falls back to whatever language is set in the browser (i.e. u click and nothing happens, no error messages, nothing). If I change the language setting in the browser all pages are translated correctly but no via de language link on the page. Any ideas? Can I force django to skip the browser setting and listen only to what is set via setlang? Or is this wrong: English (django version 1.0 svn, browser firefox 3.0.3) kind regards, -- Genís --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

It might sound confusing, but is_safe=True is a way for you to indicate to Django that your filter does not introduce any unwanted characters. See point #1 in the below doc for a more thorough explanation: http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#filters-and-auto-escaping > Shabda *wants* Django to escape the results. Here's an excerpt from the docs for that case: "1. Your filter does not introduce any HTML-unsafe characters (<, >, ', " or &) into the result that were not already present. In this case, you can let Django take care of all the auto-escaping handling for you. All you need to do is put the is_safe attribute on your filter function and set it to True, like so: This attribute tells Django that if a "safe" string is passed into your filter, the result will still be "safe" and if a non-safe string is passed in, Django will automatically escape it, if necessary." -RD --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Also, take a look at Jython which is Python written on top of the JVM
so you can call Java libraries within Python. Django 1.0 works with
Jython.

populating forms using models
Hi I'm working on a registration form which is based, among the others, on this model: class City(models.Model): prov_name = models.CharField(verbose_name='Provincia',max_length=50) (obviously i'm writing down just the field i'm interested in to save some space..) In the form i have to put a select field for the cities (form.forms.ModelChoiceField with a queryset on City) and also a select field for prov_name, in order to populate the list of choices.. Surely a different model (Provinces, and then a foreignkey on City prov_name) would be easier to manage but i can't alter the schema of the database i'm using, so i have to find workarounds.. And i can't do a modelChoiceField based on prov_name because there's no primary key, it's just a field.. Do someone have an idea on how to handle this?

Re: database API from external tools?

Your heads up on the hash issue was also most appreciated -- it's very likely I'd run into it otherwise, because I'm running python2.4 on debian (etch).

You can instantiate your form passing the request or the user as
argument:
class UserEmailForm(ModelForm):
def __init__(self, *args, **kw):
self.request = kw.pop('request')
super(UserEmailForm, self).__init__(*args, **kw)
def clean_some_field(self):
print self.request.user
...
form = UserEmailForm(request.POST, request=request)

access request.user in clean method of ModelForm
How can I access request.user in a clean method of a ModelForm?
I have the following code in forms.py:
===

class UserEmailForm(ModelForm):
class Meta:
model = User
fields = ['email',]
def clean_email(self):
email_submitted = self.cleaned_data.get('email')
email_exists =
User.objects.filter(email=email_submitted).exclude(username=request.user.username).count()
if email_exists:
raise forms.ValidationError('That email address is in
use')
else:
return email
===
When I attempt to pull up the form, I get this error:
===
NameError at /profile/update

Right at the moment, there is no easy way to retrieve a subset of the fields on a model _and_ retain the 'modelness' of the data. values() querysets returns dictionaries, normal querysets return model instances. It sounds like ticket #5420 [1] describes the feature you are looking for; there has been some work on this ticket, but it isn't available in the trunk yet. [1] http://code.djangoproject.com/ticket/5420 > Also, is using Model.objects.values() to limit the fields returned > actually more efficient than Model.objects.all() in terms of database > hits? As always, the answer is "it depends", but generally speaking, if you have a model with a lot of columns (especially a lot of large text columns), a values() queryset will be more efficient. The efficiency gains are due to the reduction in the amount of data that is being retrieved from the database, and the volume of data that is transmitted. If your database has to do less paging to return results, and the volume of data that is transmitted is lower, the results will be retrieved faster. However, if each database record fits on a single page, or the protocol overhead associated with returning a row is comparable in size to the row itself, the efficiency gains will be minimal. Also, the efficiency gains of using values() will be largely negated if you end up doing multiple values() calls to retrieve the rest of the data. If you're going to need all the data anyway, it may be faster to live with the initial performance hit.

You are right about not having the full functionality of the objects and I don't know about a way to keep it while restricting the fields retrieved by the query. > Also, is using Model.objects.values() to limit the fields returned > actually more efficient than Model.objects.all() in terms of database > hits? Not in terms of database hits, but yes in terms of the "size" of the retrieved data. If you are avoiding a lot of fields the difference in traffic size from the database can be big.

Re: Query subset
So, what I've done is use Model.objects.values() to limit the returned values, which is not ideal as I'm losing the objectness of the queryset.

I mean, if you are not sharing a subset of those fields with another model then it is ok. I think you need the values() method. It receives the fields you want to get as positional parameters (restricting the select sql query only to those fields). You can read the docs http://docs.djangoproject.com/en/dev/ref/models/querysets/#values-fields for further information.

Query subset
I have spent hours looking in the docs and one this list for an answer to this problem: I have a model that has, for example, 20 fields. On my site's homepage, where I'd like to offer a preview version of the object, I'd need to retrieve only say, half of those fields to be displayed. My dilemma is whether to simply use a Model.objects.all() query and ignore the unnecessary data in the template, or find a more efficient way to call only the data I need. Perhaps my model design is flawed and I should separate out the data that is not common to the list and detail version of the content, or perhaps I should have a model method that returns only the data fields I need, etc. Forgive me, as I'm very new to this, but I'm stumped.

This way daemon process will be restarted when doing nothing, and providing that preloading not configured using WSGIImportScript, then process size will be quite small until next needed, at which point it will load application again. To counter risk of daemon process growing in size because of memory creep in application you don't know about, also look at 'maximum- requests' option to WSGIDaemonProcess. > > Rather than event MPM, would suggest using nginx as a front end, with > > nginx serving requests for static files and then proxying other > > requests through to Apache/mod_wsgi.

If Apache/mod_wsgi only handling dynamic content, wouldn't see that event MPM would make any difference. If only handling dynamic content, turning off keep alive on Apache may help though as unlikely one will get concurrent requests over same socket for dynamic web page, and so can give up client connection straight away and not tie up Apache processes/threads for period that timeout takes to trigger for keep alive. In respect of having nginx in front, one of the over benefits of that was that nginx could have been quite selective about the URLs that it was proxying. That way if you get a SPAM bot or similar hitting the site, it could have been blocked at nginx without even going through to Apache/mod_wsgi, presuming that such a bot was hitting known URLs for security holes in PHP packages or the like. One may also have been able to filter SPAM bot traffic at nginx level through user agent or other things. Thus, nginx could have further been used as a filter point to limit traffic going through to Apache. > WSGIPythonOptimize 1 Surprised if this will make much difference. Worth a try but don't expect it to do much. For a start, as it is a long running process, any benefit at process start when loading smaller .pyo files is only for that time and not later when handling actual requests. > > StartServers 30 > MinSpareServers 30 > MaxClients 30 > If not using PHP on same Apache, better to use Apache worker MPM as then cut down on number of Apache child process and still just as capable at handling load of static files and proxying to mod_wsgi daemon processes. > Alias /media/ /data/daaku/media/ > > SetHandler None The 'SetHandler None' should not be needed here.
