defining models for unit testing only
I wrote a django 'app', thats basically just a class that takes a Queryset, some other information, and then outputs an HttpResponse object (it does some other things too). How do I write unit tests for this class? The app itself does not contain any models, yet the functionality of the class depends on a model. The testing docs do not mention anything about this. -- You received this message because you are subscribed to the Google Groups "Django users" group.

I repeat: the clean_*() functions should be methods of the
RegistrationForm class - indent them so they are at the same level as
the body of the class.
At the moment they are functions, and Django has no way of knowing they
"belong"to the form.

Variable information: client_id = Comes in from a views request... def view_client(request,client_id): c.id = Comes in from a database model. -- code -- print "%s - %s" % (str(client_id),str(c.id)) if str(client_id) == str(c.id): -- end -- The console output, displays 3 - 3 as plain as a day, this is why I am very confused on why it is not resolving.

Set Apache directive LogLevel to 'info' instead or 'warn'. This will
cause mod_wsgi to log information about when it is restarting
processes. Analyse that and see if anything stands out.
BTW, what version of mod_wsgi are you using? Update to mod_wsgi 3.3 if
you are using an old version.

Re: Ability to use PSP templates with Django?
There are 2 approaches:
- Think data structures instead, and put all this logic on your view,
such that the template just needs to iterate thru one variable to
build the menu. Something like passing in the template context:
menu = [{'name': 'django', 'text': 'Official Django Site', 'url':
'http://djangoproject.com/'}, ...]
- Write template tags for building the menu. This is the cleanest
approach, as you comprise all menu logic in a reusable tag.

You can use others, but if you're just starting off it's probably best to stick with what's built-in. Like most toolkits, there is no 1-to-1 translation between PSP and Django. They are indeed very different beasts. You are best off just learning how things work in Django and adapting to its methods and idiosyncrasies. Have you actually visited the Django web site[1]? There are tutorials and API docs and other examples. A once-through at the tutorial should give you a good idea how Django's templates and PSP differ. That should help you get started such that at least you can ask more concrete questions.

mutually referential models
As a test application to learn Django, I'm trying to model a network of
computers,
switches, patch panels and the connections between them. As a start, I have:
class Node(models.Model):
name = models.CharField(max_length=80)
description = models.CharField(max_length=80, null=True)
nodeLeft = models.ForeignKey('self')
nodeRight = models.ForeignKey('self')
# name of wire connecting to left and right nodes
labelLeft = models.CharField(max_length=20, null=True)
labelRight = models.CharField(max_length=20, null=True)
class Computer(models.Model):
name = models.CharField(max_length=80)
description = models.CharField(max_length=80, null=True)
interfaces = models.ManyToManyField(ComputerInterface)
class ComputerInterface(Node):
ipAddr = models.IPAddressField(null=True)
mbitsPerSec = models.IntegerField(null=True)
computer = models.OneToOneField(Computer)
I run into a problem because ComputerInterface is not defined at the time its
needed for
the "Computer" class:
File "/home/andy/src/django-test/netlist/nodes/models.py", line 17, in
Computer
interfaces = models.ManyToManyField(ComputerInterface)
NameError: name 'ComputerInterface' is not defined
Is there a way I can refer to a class not yet defined?
Thanks,
Andy

Enter a field in the database after encryption
Hi All, I am new to Django and while making an app in Django I got stuck at one point. What I was trying to do is to have 3 fields in my app, username, password and age. I want that if I enter my password (through admin page of my app) it got entered in encrypted format (like md5). If anyone of you have any idea how can I do this, that will be a great help.

Touch-ing django.wsgi doesn't reliably reload source code
Hello,
I have Django running under apache2 (the worker version, I believe,
with MaxRequestsPerChild set to the default, which is 0). I am using
mod_wsgi in daemon mode. I have checked that it is daemon mode using
the method described on mod_wsgi's ReloadingSourceCode page.
I need to do a nightly refresh because I get data for the db from a
coworker somewhere else. So I have a cron job that does as follows.
(1) Sets a flag "SITE_UP=False" in the code base file "site_up.py"
that shows up in each RequestContext, causing each dynamic page to say
"site is not up" since base.html looks for that flag {{SITE_UP}}.
(2) Touches django.wsgi so pages will tell visitors the site is not
up.
(3) Updates the dB
(4) Sets the flag from (1) back to its starting value
"SITE_UP=True".
(5) Touches django.wsgi.
(Step (3) takes perhaps a half hour. If there is a better way to do
what I am trying to do, I'd be very glad to hear it.)
The problem is: I come in the next morning and sometimes the pages
work, while sometimes they say "Site is no up".
If I keep refreshing a page in my browser then sometimes it works
correctly and gives me the new data, and sometimes it says "not up."
If I restart apache, the problem of showing "not up" disappears.
I had thought that Apache's children talk to the wsgi processes (I
have 4 of them), which mod_wsgi's ReloadingSourceCode page tells me
will be restarted.But obviously I'm not understanding something.
I wonder if anyone has a suggestion about how I am going wrong? I was
hopeful of finding a way to accomplish this without having to restart
apache from a cron job.
Thank you,
Jim

Always use os.path.join and you will (almost) never go wrong, and will
work cross-platform. If you need to make something into a string, use:
kmlpath = os.path.join(basepath, str(item1), str(game_id), str(subthing))
One caveat is that the encoding of a string versus the file system
encoding can differ, so you might need something different than str or
unicode. But that doesn't sound like it is your original problem.

This is likely due to the fix for this ticket:
http://code.djangoproject.com/ticket/12689, which added validation of
ModelAdmin exclude specifications. Apparently django-cms 2.0 included such
an invalid specification which used to pass unnoticed before this fix went

django-cms group:

Re: searching stackedinline fields via search_fields in admin

That example shows the syntax (double underscore) for listing related fields to be searched in search_fields. This syntax works for both forward and backwards relationships. In the example, Books are presumably listed inline on an Author's admin change page, and the very last ModelAdmin definition includes the title of the author's books among the search fields. So searching on the authors change list page will include searching on a model field that may be listed among its inline information. There is nothing automatic that will populate search_fields with such fields, if that is what you are looking for. There is also no requirement that the related models for such fields be included as inlines in the model admin, so you could include book titles among the author's search fields even if books were not listed inline on the Author's change page.

Need some help with URL layout
Hi folks,
please excuse this long-winded post, but I'm a bit stuck with the
layout of my urls.py. Let me try to explain what the site I'm using
Django for does at the moment: Basically it's a website where local
birdwatchers (the ones with feathers, not boobies ;-) can log their
observations. By "local", I mean the local district of Herford.
Noiw after several months of the site being live, I keep getting
requests from users to widen the site's scope to all of Germany or
even world-wide, which I think is a rather nice idea. So right now the
entire site lives under a common URL called "ranking", so I thought I
could restrict and calculate local and nationwide rankings using the
following URL structure:
ranking/de/hf Country: Germany, District: Herford (I'll be using
german number plates here to discriminate among districts
/ranking/de/_ALL Nation-Wide Ranking for Germany
/ranking/gr/agnAgios Nikolaos, Greece: Ranking of observers in
Agios Nik. on Crete, Greece
/ranking/_ALL/_ALL world-wide ranking
I hope you get the idea.
Ideally, I'd use the url structure to restrict the list of birds,
observations, observers and region by whatever the user provides in
the request.
I've read about mappings that you can use to pass parameters into
functions in urls.py (for instance, {"region": "_ALL"} if only a
country code is provided in the URL), but of course that means I have
to check those parameters in each and every view I write, filter()ing
and excluding within the view as I retrieve the applicable objects
from the database, which seems rather cumbersome and probably breaks
the DRY principle in a big way.
So here's my question as a relative Django noob: Is this the best way
to go about such a layout, or am I missing some critical feature
Django provides already and that I just don't know about yet? I've
read the Definite Guide to Django Book front to back FWIW.
All the best & thanks in advance for your comments & ideas,
Uwe
PS: The site in question is available at http://www.birders-hf.de/ranking/
just in case you want to check it out.

Ability to use PSP templates with Django?
I come from the world of mod_python and really enjoyed the PSP template system, where I can embed Python code directly in my template for dynamically generating menus and such. What is the recommended method of calling a PSP template from inside Django and rendering it? Here is a sniplet of code I am trying to convert over to the Django template engine, but cannot figure out the best method: for name, text, url in menu_items: attr = "" if name == hlight: attr = "class='highlight'" # begin %> ><%=text%> <% # end %> And yes, this menu code is from the mod_python example site. Also does Django include an example fully working site to display most, if not all of it's abilities? The example site which mod_python includes is very simple, but is a great starting point for a website. mod_python's example site is here: http://modpython.org/examples/ I really think having such an example for django would be good as well. I am actually in the process of basically re-creating this example site in django to learn how django works and how it differs from mod_python coding. -- You received this message because you are subscribed to the Google Groups "Django users" group.

The effect of this statement is to allow the import of any module (or
package) in the /home/myproject directory.

This would imply that your settings.py lives in
/home/myproject/myproject/
if you want to use the path entry you just added. Is this in fact the
case? Usually, for testing, you can rely on the fact that the directory
containing the program you run (manage.py) is added to sys.path
automatically by the interpreter, and there is no need to muck about
with sys.path. And there would be no need to set the
DJANGO_SETTINGS_MODULE manually either.

In which case you should be adding /home to sys.path if you add
anything. But that's not a terribly good idea.
Try removing the sys.path.append and the os.environ setting, and then use
from models import *
(though in fact importing specific names is much better, and it's
actually quite unusual to have a models.py in the top-level project
directory - but I see you already know that. Sorry!), and
from app.models import *

I think you are simply slightly confused about the Python sys.path.
I hope this has helped. You'll get there soon - keep trying!

Re: Path mess
Thanks for your quick replies. You helped me to understand what is
happening.
However, I can not make all work together. Let me explain the problems
that I am having right now...
I wrote a piece of code in a folder within my django project path just
like this:
/home/myproject/utils/commserver.py
So using my new knowledge I wrote a program just like this:
import os, sys
sys.path.append("/home/myproject")
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'
#I need the models form an application
#the aplication is included in INSTALLED_APPS
#importing models like this "from myproject.models import * raises the
same error
#i imported * just for testing purposes
from myproject.app.models import *
and the following error is raised:
ImportError: No module named myproject.app.models
#/home/myproject/app/models.py do exist
i also tried to import something from django, so I removed the
previous import and i wrote:
from django.db.models import *
and the following error is raised
raise ImportError("Could not import settings '%s' (Is it on sys.path?
Does it have syntax errors?): %s" % (self.SETTINGS_MODULE, e))
ImportError: Could not import settings 'myproject.settings' (Is it on
sys.path? Does it have syntax errors?): No module named
myproject.settings
Is it on sys.path? Yes Sir, i appended to sys.path
Does it have syntax errors? I believe not Sir.
And now is when i understand nothing.

how to prepopulate admin form with default data?
class Notes(models.Model):
name = models.ForeignKey('name', blank=True, null=True)
text = models.TextField('Text',blank=True)
date = models.DateField(blank=True, default=datetime.date.today());
I have a simple admin model for inputting a note with a date into the
database.
date is prepopulated automatically with the current timestamp. I want
to
automatically prepopulate the name with the current logged in user
name.
Does anyone know how to do that?
Any help is appreciated.
Thank you
