Re: DATE FORMAT ISSUE AGAIN.
Kindly execute the code that i wish to do from django it self
# Simplyfied date format change that I wish to use in django
import datetime
t = datetime.date.today()
print t.strftime("%Y,%m,%d")

print t.strftime("%d,%m,%Y")
Can't i call this program to django to change the date format. if yes

Re: DATE FORMAT ISSUE AGAIN.
Thanks James but the spaces had been removed
If Spaces it gives template error.
If not it gives the former error
says
AttributeError at /registration/
'FormFieldWrapper' object has no attribute 'month'
had resolved
But not able to change the date format still
I tryed to poke the source code of django
that have a file json.py
at line number 35 their is a class stated as
class DateTimeAwareJSONEncoder(simplejson.JSONEncoder):
"""
JSONEncoder subclass that knows how to encode date/time types
"""
DATE_FORMAT = "%Y-%m-%d"
TIME_FORMAT = "%H:%M:%S"
Does it makes any sense. sience I have already installed the django. I
don't guess that should work here.do i reinstall the django with the
DATE_FORMAT Change to "%d/%m%Y"
?

Copying objects in admin
Hi guys When you click the "Save and Add Another button" in the Admin, the values are cleared and all need to be re-entered for the new object. How would I go about saving that existing object and then transferring the field values to the new object. This would save a lot of time for some models, as the data largely stays the same, bar a couple of fields. And thanks Malcolm for your previous help, trying to implement things differently...

This model requires that the fields app_label and model are a unique pair.

Also, keep in mind that you can tell svn to ignore a particular file even though it is located in a working directory. We keep a settings.py under svn control, and have it import a local.py which is ignored.

For example (untested, but should come close): def save(self): ... for d in date_list: new_obj = Schedule(**self.__dict__) new_obj.date = d new_obj.save() The uses the fact that you can create a new model using the field names as keyword arguments to __init__ and that the __dict__ attribute will (for a typical model) contain only the field attributes. My only slight qualm here would be that it's a bit weird to use one model's save method to do almost everything but save that instance of the model: it makes lots of new objects and saves those. Still, that could be argued as being a matter of taste, so it's not a technical obstacle. You probably do want to make sure you also save "self" at some point in the above method, otherwise there would be no way to do it.

Saving a model instance multiple times
Hi, I was wondering how you would go about saving a model instance multiple times (having seperate db entries) while changing just one or two fields each time. I'm wanting to use a single series of inputs that define the parameters to create/save multiple event objects to the database. Just to give you a better idea of what im trying to do: class Schedule(models.Model) ... date = models.DateField() ... def save(self): date_list = [..] for d in date_list: self.date = d super(Schedule, self).save() Any suggestions, example code would be much appreciated, Cheers --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Write your own __init__() method on the Article class and make sure you call Model.__init__ (or super(Article, self).__init__) as the very first thing. The Model __init__ will initialise your class by loading any data into the attributes. Then your own __init__ code can copy those original values to another attribute somewhere in the object. Inside your save() method, you compare the attributes you are saving to the ones you copied aside in the __init__ method to work out any differences. Normally we don't need to write __init__ methods on models, so I wasn't thinking along these lines. Whilst pushing the vacuum cleaner around the living room just now I realised I'd missed something obvious.

Can you post an example of the sort of urlpatterns -- with the arguments -- you have that are failing, please? There's nothing in urlresolvers.py that should be causing this problem (all the default argument use is thread-safe) but I'm wondering if you are using mutable types as your default arguments and then modifying them in place (the equivalent of "def foo(somearg = []):..."), which is a bad idea for just the reasons you are seeing.

I'm not going to give you a full example, but this problem is raised
here fairly regularly (the most recent time being yesterday). The normal
solution is that the Django view queues the request to do the extra work
somewhere (e.g. a field in the model to say "needs encoding") and
another, external process comes along and does the work. The external
process might be triggered by a cronjob, for example -- it can check if
there is any work requests in the queue and handle them, otherwise just
exit immediately. The point is that the external process is not
triggered by a view or anything else that is tied to requests, so no
user's experience is affected.

Greets all, Been having the most bizarre issue for quite some time now; it seems as if the 'kwargs' portion of various URLpattern objects/views are 'bleeding' into one another once the server has been under moderate load for at least a short period. I will have e.g. a specific view that displays/processes a form, whose template context will intermittently become corrupted and contain information that belongs in *other views' contexts*. For example, the context contains a couple objects, such as session username and object being edited, but then it will sometimes end up with those objects *in addition to* an object_list that comes from a list view, or a 'no_javascript' boolean that I set in some views to disable a template level Dojo include. This problem only crops up after the server has handled at least a few dozen requests, and even then is only intermittent - I can load the same form a dozen times and the incorrect context appears 2-3 times, sometimes with different sets of incorrect info. I have debugged the issue as best I can and it appears to reside in django.core.urlresolvers.RegexURLPattern - these objects set up their 'default_args' attribute when initialized (always correct at that point), and then refer to that value in their 'resolve()' method (at which point the corruption appears). I can't find any bug reports or mailing list posts about this issue, and while I plan to file a ticket I wanted to post to see if anyone had any other bright ideas. This issue occurs with 0.91 and 0.95.1, with mod_python as well as the development runserver, always Python2.4 (on varying Gentoo systems, fwiw).

There's no one-line method, but it's pretty easy to do: write a custom save() method on the Article class that retrieves the instance again and compares the fields. Something like def save(self): if self.id: original = Article.objects.get(id=self.id) # Compare fields you care about super(Article, self).save() The reason this can't really be done any more simply than that is that the attributes on an Article instance are just normal Python attributes -- there is nothing Field-like about them until you do the saving. Python has no automatic way to tell if a class's attributes have changed between two points in time.

There's no compulsion to have settings.py inside the project directory (it also doesn't have to be called settings.py, so you can put the settings files for a number of projects in the same directory if you name them carefully). For my personal work, I keep my settings.py files for production settings outside of the project directory so that I can just untar the new version of the code, update a symlink to the latest version and reload the webserver process, without needing to remember to update the settings file.

Re: WHAT IS DJANGO?
The Django you're looking for is here: http://webpages.charter.net/django/ It's apparently a program for printing tablature for various fretted instruments.

Re: Starting a new, external process
Hi!
I had exactly the same problem. I solved it by having Django write the
Video file to a directory. In the background, a process checks every
couple of seconds if there is a new FLV to convert. This process is
completely independent of Django. You might want to start it with an
init.d script or something.
This process could be something simple like this bash script:
#!/bin/bash
while true
do
for i in *.avi
do
MAGIC_MENCODER_COMMAND_GOES_HERE $i $i.flv
rm $i # remove the original file, or move it
done
sleep 5 # wait a few seconds
done
(I have not tested this, just to give you an idea)
Your code could of course be way more sophisticated, like spawning a new
process upon a signal or whatever.
I hope you find this useful.
Regards,
Daniel

Re: Starting a new, external process
I don't have a full example, but the thread module won't do what you
need. You need to spawn an external process to do your job. For this
take a look at python's documentation. It's a faily simple thing to
do, if you just want to run mencoder on the file,

Re: newforms and templating
You might take a look at BaseForm._html_output(). It's the function that does most of the work for .as_p() and so on.

Django models, detect whether value comes from db, or has explicitly been supplied.
Imagine the following model: class Article(models.Model): title = models.IntegerField() Then when you do case 1): art = Article.objects.get(pk=1) art.title = "New title" art.save() or case 2): art = Article.objects.get(pk=1) art.save() Is there a way that the model, before saving, knows whether the title (or any other field) has been reassigned?

Starting a new, external process
Hi there!
I have a model which allows people to upload videos.
In the save-method I run os.system("mencoder *variables"), which
converts the uploaded video to a flash file.
I don't want the user to have to wait until the conversion is done
before he can go on with his business. I've tried the Thread-module,

One simple way will be to add a simple JavaScript clock countdown in your application. You can find many examples online, or even ready scripts. You have to make sure on the track the time used on the server side though - you should register the time at which user got the test and the time at which he submitted the answers, at the very least. If you have multiple pages/forms, make sure you register the time at which the user requested each page and adjust the countdown accordingly. Do not implement this with some random script entirely on the client side, as then it'll be very easy to cheat. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Checking whether an app is installed?
Actually, the order of the apps in my template is also customized, so
it seems, that I'll have to create an template tag, taking an app
name, comparing it to settings.INSTALLED_APPS and returning a boolean
variable, i.e.
{% check "auth" as is_installed %}
{% if is_installed %}
... show links to administration lists ...
{% endif %}
But thanks, anyway.

Re: DATE FORMAT ISSUE AGAIN.

And that object doesn't have a "month" property, so it raises the AttributeError exception. This might stem from assigning a non-date value to a DateField value, and then trying to read it back. Or it might stem from assigning None to such an attribute (though IIRC, that raises something like "'NoneType' object has no attribute 'month'". Or you might be passing something that's a non-date to a "date" filter. -tkc --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: django install on mac osx 10.4.8
Hi everybody, hope you're all good out there. I did a few progress with my install. i installed python 2.4. with this install instead of the latest one i could install django with the sudo python setup.py install command. but now i can't seem to start a project. when i do the import django line in the terminal i do not have any error message again but when i try the django-admin.py start-project testsite i get a syntax error message File "", line 1 django-admin.py start-project testsite ^ SyntaxError: invalid syntax it says on the documentation page that djang should be installed in a sit-package folder and that the installer should have linked to it. when i check in my library folder, django is installed inside the bin folder of the current pythin version. would it be the reason why it can't connect to the django admin file? and how can i reset this link? cheers On Mar 12, 4:40 pm, "Jay Parlar" <[EMAIL PROTECTED]> wrote: > On 3/12/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > > > > nope i do it from home, never had any problem before, not like i would > > really have known anyway got problem all the time :), > > problem isntalling this and that, problem installing rails and so on. > > shame i really want to give a try atdjangoreviews looks good, better > > than rail for a designer like me. > > I recommend staying away from DarwinPorts.

Deployment with Subversion
Hello, how do people deploy Django projects with subversion? We did a simple checkout at a client's and when we need to do updates, we copy his settings.py file somewhere outside the directory, do the svn update, we copy the settings.py file back in and do a graceful restart of Apache. Does anyone have tricks to make this process a bit more efficient and not catastrophic in case we forget to copy the settings.py file?

Newforms - Dynamic Fields from a queryset
I wonder if anyone can give me some pointers. I've been working with
new forms with reasonable results, but I've come across a problem when
creating a form with dynamic fields and rendering to an HTML template.
I want to create a form using data from a queryset which extracts data
for a specific user. Alongside each row, I want to place a checkbox
which the user can tick to indicate their preference.
The output table would look something like this:
Points Type Points Select
Points Type 1Points Select
Points Type 2Points Select
Points Type nPoints Select
The intention here being that the user can select one or more rows and
use them in further processing.
I've defined the form class as:
class MyForm(forms.Form):
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs)
qs=UserPoints.objects.all()
for i in qs:
self.fields['type_%s' % i.type_id] = forms.CharField()
self.fields['points_%s' % i.points] = forms.CharField()
self.fields['select_%s % i]=forms.BooleanField()
In my view I call the form and return the response to the template.
myuser=request.user
if request.method == "POST":
form=MyForm(request.POST)
if form.is_valid():
etc
else:
form=MyForm()
context = Context({'form':form)
return render_to_response('mytemplate.html', context)
My issue is that I want to be able to filter the form queryset so that
it only shows the specific user's records - can anyone suggest a way
to do this.
I also want to output the various fields on the form in the HTML
template, but I can't work out the correct syntax.
I'm probably doing something daft through lack of experience. However,
any insight gretaly received.

Currently, the list of apps on the default admin index page is
generated by the 'get_admin_app_list' template tag, which just returns
a list of apps. If all you need to do is show some content along with
that app's stuff on the index you can do something like
{% load adminapplist %}
{% get_admin_app_list as app_list %}
{% for app in app_list %}
{% ifequal app.name 'myapp' %}
...do your special stuff here...
{% else %}
...do the normal stuff showing links to add/change model instances...
{% endifequal %}
{% endfor %}

When you use form_for_model, the deafult import_formats argument that
gets used does not include '%d/%m/%Y'. It is expecting '%m/%d/%Y'
among other things.
The most straightforward solution would be to create a custom form
class instead of using form_for_model. There are a couple of other
options, but they're a little tricky if you aren't familiar with
Django's internals. Look at the docsting and code for form_for_model
for clues on the other 2 options and feel free to ask questions if it
doesn't make sense.

Writing the same service using twisted works just fine, so at the moment Im using a really dirty workaround by making an xmlrpc-call to the twisted server telling it to execute my command instead. Shutting down/restarting the twisted server works without a problem even while starting any amount of services (be it any in /etc/init.d or my custom services). > One way to check this out would be to check out the state > of /proc//fd and the like (it sounds like you're on a Linux system) > to see if there are file handles to your subprocess command still open. > Basically, you need to investigate at the sytsem level and work out why > the python function does think its work is done yet.

Judging from /proc/pid/fd everything is as I would assume it was: just a config file, a log file and three sockets open (in my case, the program listens on three ports), And three references (Im assuming stdin, stdout, stderr) to /dev/null. Same with any other daemon I've looked at. Since it works ok from the command line or from a twisted service, I can only assume its not where the problem lies. UPDATE: Ive tried getting it to work with mod_python, but all kinds of permission issues and environment issues came biting me when I did, so Ive decided to stick with the xmlrpc-server solution for the time being. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

models.ForeignKey problem
Hi again,
I'm trying to model a software project
So I have the following models (slightly abreviated):
class Project(models.Model):
name = models.CharField(maxlength=80)
class Software(models.Model):
name = models.CharField(maxlength=80)
version = models.CommaSeparatedIntegerField(maxlength=5)
project = models.ForeignKey(Project,blank=True,null=True)
software =
models.ForeignKey("self",blank=True,null=True,related_name="extra")
The thought behind this is that a software project might contain some
basic software and then additional software pieces (e.g. extentions).
So a specific software piece can either be part of the project or be an
extension made by someone else for whatever reason and would therefor
not be counted as part of our project but would definitely be connected
to the base implementation.
Anyway, that's a side issue.
The problem I have with this is that when I try to add a software using
the admin interface, I get the following error:
Exception Type: AttributeError
Exception Value:'bool' object has no attribute 'get'
Exception Location:
/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/django/db/models/related.py
in get_manipulator_fields, line 119
I've verified that the problem is with the software->software connection
(I think) since if I remove that attribute from the class everything
works as planned.
So, what have I missed ?

Nested edit_inline?
Hi all, Is there a way to have nested inline editing? For example, I have a Poll model which can have multiple Questions - which, of course, can have multiple Answers. I tried adding edit_inline=models.TABULAR to both the Question and Answer models, but of course, it didn't work. I can edit a question and see all of the answers inline, and I can edit a poll and see all of the questions inline. But what I want is to edit a poll and see all its questions, each with its associated answers. Is this possible? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

newforms dateField
Hello, I have noticed that the field DateField in the newforms library
doesn't validate all right when introducing data.
I have this code:
FormClass = forms.models.form_for_model(Model)
form = FormClass(data)
data = request.POST.copy()
data['author'] = request.user
formulario = FormClass(data)
if form.is_valid():
form.save()
And I get a validation error, meanwhile, when I validate using the
shell with the following code, it's ok:
>>> f2 = forms.DateField(input_formats=['%d/%m/%Y'])
>>> f2.clean('25/10/2006')
datetime.date(2006, 10, 25)
What's wrong in the first case?
Thank you.

If 30 mins test, then count down will > start from 30 mins : 00 Secs, 29 min: 59 secs and so on. How > do I do this? In a word: unreliably. Common attempts make use of JavaScript and Meta-refresh hacks. However, unless you control the browser environment (such as a testing lab), these can be readily disabled. I run FireFox with the NoScript and RefreshBlocker plugins, both of which prevent unsolicited "push" activity. Anybody who puts a meta-refresh on a page containing form-input should be smacked. As for scripts, nothing prevents a test-taker from using a JS debugger to increase the allowed time. The only way to come close to doing something of the like is to track all time on the server side, from the initial page delivery. Once the time on the server surpasses (initial_time + time_delta) the server reacts accordingly to submissions. This would be the only Django-related issue for the most part. In this case, clicking on the "begin the test" form button would post back to the server, allowing you to create a "test" entry containing the current time, and then redirect the resulting page to change the POST to GET so that reloads to re-post back the test request. Disadvantages: * a person can start the test, have a personal issue (such as a restroom break, medical issue, or what have you) and step away from the computer without realizing that the timer is still ticking. Or network difficulties (dropped aircard connection, back-hoe interruptus, ISP difficulties, FAA requirements for turning off wireless devices before takeoff, etc) * if all your questions are on one page, and they submit the whole thing a fraction of a second after the time expires, and they get no credit for any of their answers * if you have a page for each question (preventing the previous problem) you then have to take into consideration page-load times if, for example, the person is on a slow dialup or aircard connection. If your test is 30 minutes and 5 of those are spent transferring pages over a slow connection, is the test-taker penalized? One's not precluded from using a combination of the above in concert, so you can use the server-side stuff, with client-side JS that will update a count-down timer in a somewhere, or to submit the form when time's up. Just don't rely on functionality that may not be there. Just a few thoughts for your consideration. -tkc --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: referncing a model within a model
It's the traversing the multiple relations in my template I'm having
trouble with, my models are something similar too:
Team(id, name, squad, manager,,)
Fixture(id, team_id, date, opposition, location)
Result(id, fixture_id, home_score, away_score)
In my Team_Details.html template
I'm showing things like
Team Name: Man Utd
Manager: Alex Fergusson
.
Upcoming Fixtures:
Date: 12/03/07
Location: Home
Opposition: Chelsea
And I want to have (but I Don't know how)
Recent Fixtures:
Date: 09/02/07 (date from Fixture model)
Location: Home
Opposition: West Ham
away_score: 1
home_score: 4
This is my template:
<< Team list
{{ object }}
Squad
{{ object.squad }}
Ground
{{ object.ground }}
Manager
{{ object.manager }}
...
Home Ground
{{ object.ground }}
Sponsor
Fixtures
{% for fixture in object.fixture_set.all %}
{{ fixture }}
{% endfor %}
Results
{% for result in team.result_set.all %}
{{ result }}
{% endfor %}
Results Test
{% for fixture in object.fixture_set.all %}
{% for result in object.result_set.all %}
{{ fixture.date}}
{{ result.howdenscore }}
{{ result.opponentscore }}
{{ fixture.opponent }}
{% endfor %}
{% endfor %}
However neither attempt at showing a result work, any help is much
appreciated.

Re: low performance of FastCGI deployment
The web pages served in my django applications are not static media files, but dynamically generated content (the result of applying XSLT transformation to the XML data retrieved from XML database). I consider the architecture of public site with static version of data and private dynamic site, but the problem of synchronization of the two systems is not trivial in my case. Though i agree that serving big dynamic content will fail with increasing the number of users. P.S. Your writeup is very exciting and interesting!

Re: Model question
Thanks guys, I guess I'm in the right path then! Duncan, it's a good idea but I'm not sure I want to mess with parsing logs in my main app; I'd prefer to centralize everything on the db. Thus, I'd rather go the route suggested by Rubic and Carole. I'll try to implemente it with a "date_now" field on a new table and I'll let you guys know how it goes.

Grabbing information from three models is no harder than from two. Just create the models exactly as you describe. Probably a couple of foreign keys from Fixture to Team (one for each team) and another ForeignKey from Fixture to Result (or vice-versa). QuerySets in Django allow you to traverse multiple relations in one key. So just try it and see. If you are still having problems, it will be a lot easier to help you if you have attempted to create some models so that we can point to specific lines of code. At the moment, it is a bit too up in the air to see exactly where you are having problems.

Not sure if this is what you mean, but you can extend files in
different directories.
e.g.
{% extends 'base.html' %} -- base.html in same directory
{% extends 'subdir/base.html' %} -- base.html in a subdirectory
{% extends '../base.html' %} -- base.html in parent directory
{% extends '../sibling/base.html' %} -- base.html in another directory
at the same level
You could also have multiple template directories in your settings.py:
TEMPLATE_DIRS = (
'/path/to/templates',
'/path/to/templates/member',
)
Then when you use extends, I believe Django will look in the different
template directories to find the base. You would probably use
different filenames e.g. base.html and member_base.html.

Re: why does django display th/td:hover style incorrectly ?
I'm not sure about IE7, but all the previous versions of IE certainly
didn't support hover for other html tags than . So it is
not Django issue at all. If you need some browser specific special
effects, use javascript for IE.

Please put some effort into supplying enough information that we might be able to understand what problem you are seeing. In this case it might be relevant to know: (a) How you are generating the HTML in question (since you are implying it's a Django-specific thing, so you need to work out which role Django is playing in producing the output). (b) What HTML is being generated. (c) What you are seeing and what you expect to see. (d) What browser/OS combination(s) you are using, since display is a very browser-sensitive issue. Does the problem appear on multiple browsers? At a minimum, start trying to work out (and demonstrate) what Django is rendering, versus what should be rendered. If it's a display bug, it means the generated HTML is somehow wrong, so find a (short!) fragment of the HTML that is incorrectly generated so that we can see it.

This is different from the problem you are trying to solve on
django-dev. This one is actually a bug: we bail out at the first
attempted match, rather than continuing on if we fail. It's ticket
#3525.
If we have clearly different parameter sets to match, there's no
ambiguity about which one to select.
This will be fixed shortly.

Malcolm

I am afraid that currently, there isn't a out-of-the-box
implementation of that type of filters in the admin panel. It's more
of a true interface for administrators, rather than a proper content
management insterface.
You'll probably have to extend some control and modify the necessary
view from the admin panel, if you want it to go there. If you're using
the newforms admin - it might be easier to write that there.

Re: Integrating web services with django

You can do whatever you want inside a view function and there is a view for every single URL the application can handle. So you would only need to write a view that does whatever processing you want to. It's difficult to be more specific than that because, as I said "web services" can mean anything. For each particular case, the design work comes down to working out which URLs correspond to which views. There are some pages in the wiki giving examples of how people have thought about hooking up xml-rpc calls through Django. Implementing REST URL schemes is almost trivial (at the URL mapping level), since it's just pattern matching and view dispatching. All the hard work lies in writing the view function to do the real heavy lifting and that varies on a case-by-case basis. > How can I deal with invocations/jobs which take a long time i.e > several hours, and still enable the user to come back later and view > the result of the job from the web service.

This has been discussed in a lot of other threads on this list (search for "long running processes" might be one place to look). Basically, anything that prevents the view from returning as fast as possible is a bad idea, because the client is waiting. So if it really is going to take a long time, the view should just shove the request in a queue and some other (external) process will come along and run items from the queue periodically.

Have a look at the "ifchanged" template tag (it's a standard one in
Django). This allows you to control the displaying of a line based on
whether some value has changed since the last time you checked it.
In my blog software, for example, I have a section that says
{% ifchanged %}
{{ entry.creation|date:"D, j M Y"
}}
{% endifchanged %}
inside the loop that displays the articles on a page.
This will only display the day and date header if it has changed from
the previous article (the previous time around the loop).

Malcolm

Have a field in your model that allows you to select which template to use as the "default display", so you store it with the model. Note that you won't be able to use standard generic views to do the displaying in this case, since the generic views requires the template to be used to be passed in as part of the function call. However, you could easily write a short wrapper around the generic view that extracts the template name from the object and then calls the real generic view with the right parameters. Or just not use generic views at all (I'm only guessing that you are using them in the first place; maybe you aren't). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Or, maybe django has already handled this so that as long > as the two front end django application server shares the same > database, it should be fine? Short answer: "yes". Longer answer: The signal module is a purely intra-process software implementation of signals -- it operates entirely using Python function calls. So the effects will not even be visible outside of the process that calls signal.dispatch, let alone the machine.

I suspect this really a Django problem. It sounds like, despite the attempt to daemonize the process, the init script isn't properly shutting down or something and so the process that is executing mod_python and that particular view hasn't finished yet (it still has a child process). One way to check this out would be to check out the state of /proc//fd and the like (it sounds like you're on a Linux system) to see if there are file handles to your subprocess command still open. Basically, you need to investigate at the sytsem level and work out why the python function does think its work is done yet. There is nothing really Django specific going on here that I can see, but deeper investigation may prove otherwise.

Look up the "ALTER TABLE" statement in your favourite SQLite reference. That is the command for changing the types of columns, adding constraints (which is what you want to do here, by adding "NOT NULL" to the column), or adding or removing columns from the table. > I guess this must be a reoccurring topic when you are modeling a new > site since you never get it right the first time around. Quite often when you're initially developing models, you don't have any valuable data in your database, so you can quite happily use the "sqlreset", "sql" and related commands to manage.py to drop and recreate the database tables. Once you have data that you don't want to lose, or are migrating an existing production version to new models, you use "manage.py sql ..." to dump what the SQL should look like, work out the changes from your existing tables and then use things like "ALTER TABLE..." to bring the database into line.

Related foreign fields in admin application
I am a python and Django novice so please excuse me if my question is
too stupid.
I have 3 models: Regions, Municipalities and Persons.
In the admin interface, when editing the Person object, I want to
limit the choices for the Municipalities based on the Region choice
(e.g. I want to limit the list only to Municipalities that are in the
chosen region). Please advice me which is the best way to do that.
Here follow my models:
class Region(models.Model):
region = models.CharField(maxlength=128)
def __str__(self):
return self.region
class Meta:
verbose_name = 'Област'
verbose_name_plural = 'Области'
class Admin:
pass
class Municipality(models.Model):
region = models.ForeignKey(Region)
municipality = models.CharField(maxlength=128)
def __str__(self):
return self.municipality
class Meta:
verbose_name = 'Община'
verbose_name_plural = 'Общини'
class Admin:
pass
class Person(models.Model):
PERSON_TYPES = (
('Да', 'Юридическо лице'),
('Не', 'Физическо лице')
)
region = models.ForeignKey(Region, null = True)
municipality = models.ForeignKey(Municipality, null = True)
name = models.CharField(maxlength=384)
type = models.CharField("Юридическо лице", maxlength=8, choices =
PERSON_TYPES, default = 'Да', radio_admin = True)
dnomer = models.CharField(maxlength=16, blank = True)
bulstat = models.CharField('БУЛСТАТ', maxlength=16, blank = True)
egn = models.CharField('ЕГН', maxlength=10, blank = True)
city = models.CharField(maxlength=64)
postcode_p = models.CharField(maxlength=16, blank = True)
address_p = models.CharField(maxlength=128, blank = True)
phone_p = models.CharField(maxlength=64, blank = True)
def __str__(self):
return self.name
class Meta:
verbose_name = 'Юридическо лице'

Sort by output of arbitrary method
According to the tutorial: "You can click on the column headers to sort by those values -- except in the case of the was_published_today header, because sorting by the output of an arbitrary method is not supported. " Well, I understand that it would not be as efficient to sort on an attribute that isn't a field of the database, but is there an easy way to make the admin do this anyway? Barring that, since most databases support min max and average, is there a way to sort on those aspects of a field?
