Re: Multiple one-to-one relationships for a single class
Hi Malcolm Thanks for the awesomely quick reply. I'll give the foreign key option a go for now and maybe dive deep later. I'm assuming that I could check for say an existing event detail record when I try and create a new one as well - probably cause less user angst.

Re: Initial value for a choices field in admin?
Thanks Jake.
It works like a charm. I thought I tried this before, so I obviously made some
mistake.

Multiple one-to-one relationships for a single class
Hello Is it possible to have multiple one-to-one relationships for a single class or is there a better way to do it. What I have is an event which has about 12 fields. Optionally any combination of a single weather record, a single event detail record, a single survey record and one of four event subclass records may be stored against this event. Each of these optional records has between 5 and 12 fields each. I could put everything in one big table with lots of nullable fields but that is not my preferred option. Any help would be appreciated. Thanks Catriona --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Yes, it's true that if self.id (or whatever the primary key is) does not exist, then it's a create. However, just because self.id exists does not mean that it's an update. The Model class has a mechanism in save() that checks to make sure that the primary key exists in the DB. If it doesn't, it will do a create. Unfortunately, as it currently stands there's no way to distinguish this case without doing the SELECT on the PK yourself (the query or its results aren't accessible to user code in any way right now), which is why I recommended the post_save signal pending Trac ticket #4879's acceptance. gav --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: insert or update
As far as insert or update, just overide the save method within the class. It is something that must be done for each class, but what I have done (for essentially the same purpose) is override save() on each model I need to log the action for like so: def save(): # if id exists, this record has already been created if foo.id: # create the log entry for an update else: # create the log entry for an insert super(foo, self).save() Do the same for delete() To make it easier I have abstracted my save and delete methods, they are defined as methods within my apps models.py and the individual model classes call them, passing (self) and getting back a 'model_instance' object for user with the super.save() -rfd On Aug 21, 1:20 pm, "Lic.

There isn't a solution to your particular problem. Your problem is that you are accepting invalid data. Nobody can be born on a day that doesn't exist.

It's just noise in the end. With thousands of people using Django, it's pretty much a given that any feature is going to have some non-zero amount of people wanting to use it for some purpose. Frankly, one person or six people or even 20 people saying they would use something isn't statistically representative. It's a self-selecting sample, for a start, and is a very small fraction of the user-base without reflecting the counter-arguments. The unintended downside is that lots of "I would use this" comments in Trac makes it harder to extract out the substantive technical comments about a ticket. That might sound harsh, but Trac is for tracking tickets, not as a voting mechanism or a place to resolve design discussions. I say this with all due respect, but as somebody who has to go through all the tickets that are filed and read the comments (and non-comments) and as somebody who often helps to make the decisions. You aren't helping yourselves by adding such comments and you're hurting others. Design discussions happen on django-dev, not in Trac.

the 'default' keyword argument should work, but be sure to use the
stored-value (first) element from the stored/representation tuple you use.
ie if your UNITS tuple is defined
>>> UNITS = ( ('in', 'Inches'), ('cm', 'Centimeters'), )
you'll want to use
>>> class MyModel(models.Model):
>>> units = models.CharField(maxlength=2, choices=UNITS, default='cm')

you can use something like:

where modelinstance is an instance of your model and myfield is the name
of the field you want to inspect.
is that what you're looking for? newforms form_for_model also brings

Re: Mod_Python and Apache
The official mod_python mailing list details are at www.modpython.org. You posted to the mod_python Google group which no one uses. Also look through: http://blag.whit537.org/2007/07/freebsd-threads-apache-and-modwsgi.html and specifically the other pages it links to. You may need to work out which threading library Python is wanting to use and which Apache may be picking up. If they are different you may need to tweak system config file to override which threading library is going to be used so it is consistent and no possibility of conflict. You might also try and find a FreeBSD specific mailing list to raise your problems. Also try mod_wsgi perhaps, but if it relates more to mixing Python and Apache, then would expect you to see the same problem.

Re: Problem using external CSS file with template
While I was writing reply to you Will, I've decided to try once more, just to make sure that I didn't make some stupid mistake, and surprisingly it worked! Only difference is that I've tried it on another computer. Now I know for sure that there is nothing wrong with Django or me. It's relief :) I suppose that it will be much easier now to figure it out why it didn't work on my development computer. Thanks for your help.

Re: Importing Excel/CVS into Database
Yes, I've done that. The following function read_excel_csv works with
Excel CSV files saved on Mac (I can't remember exactly, but it might
be that MS Office for Mac OS X saves CSV files using different
separators than on Windows). The function reads the rows line by line,
parses the cells of each row and passes the values in a list to your
custom function.
###
import csv
def test(l):
print l
def read_excel_csv(filepath, function):
f = open(filepath, "rb")
line_list = "".join(f.readlines()).split("\r")
reader = csv.reader(line_list, delimiter=";", doublequote=True)
for value_list in reader:
function(value_list)
>>> read_excel_csv("/some/path/table.csv", test)
###
Good luck!

I do this day in and day out :)
I prefer tab-delimited because it's easy and clean, though
Python's built-in "csv" module can ease the pain of working with
csv (which I presume you mean, rather than CVS, which is the
Concurrent Versioning System)
I usually just write INSERT statements by hand, directly using
the DB interface for my backend (PostgreSQL in this case) and
then run a little Python code to iterate over the file and spew
the data into the system:
filename = 'foo.tab'
for i, line in enumerate(open(filename)):
if i == 0: continue # skip the header row
(fieldname1, fieldname2, fieldname3 ...
) = line.rstrip('\n').split('\t')
cursor.execute("""
INSERT INTO app_foo
(f1, f3, f2)
VALUES
(%s, %s, %s)
""", (fieldname1, fieldname3, fieldname2)
)
You may have to do lookups into other tables, etc, but this is
generally how I do it. Things can also get fancier if your input
file can have the columns in any arbitrary order. The above simply
From within a running Django app, you can make use of the ORM to
ease some of the annoyances, but when bulk-loading the data
repeatedly (several thousand rows of data, multiple times per
day), I personally like the control of raw SQL to eke out the
last bit of performance from my DB connection.
I've seen some tools that try to ease this for you, but I've
never been impressed by them, as I end up spending as much time
fiddling with them as it would take me to bang out some python
code to do the same thing.

See this page: http://code.djangoproject.com/wiki/Signals The ones that are most important to you are (pre|post)_save and (pre|post)_delete. With this, you can distinguish between an insert/update pair and a delete. However, part of your question, distinguishing between an insert and an update, isn't yet part of the Django core. You could try checking for the ID while you're in one of the signals, but that's not exactly reliable. This ticket would give a "created=True/False" on the post_save signal, which would allow you capture exactly the information you want: http://code.djangoproject.com/ticket/4879 If you need that functionality, add a vote for it. :) Anyway, with these bits, you should be able to add the signals in your app to catch all the changes, and then you could write them somewhere. Either hook into the Admin app and continue adding to the logger there, or start using an AuditTrail to track *all* changes and keep a full history of them. http://code.djangoproject.com/wiki/AuditTrail Good luck! gav --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

How to make a mapping/alias db table? (many-to-many)
I've had 20 tabs open all day, all displaying django docs - but I can't work this out. A bookmark can have many categories, and a category can be in many bookmarks. So I just want a simple table that consists of category_id, bookmark_id >From the docs I thought Django would create this automatically but syncdb doesn't add it. How do I add categories to my bookmarks? Here are the models: class Category(models.Model): name = models.CharField(max_length=255) class Bookmark(models.Model): name = models.CharField(max_length=255) description = models.CharField(max_length=255) url = models.CharField(max_length=255) categories = models.ManyToManyField(Category) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Template within a Template?
Actually I need another clue... I'm getting very confused about how to structure my Python projects/ apps. In settings.py: TEMPLATE_DIRS = ( "C:/Python/my_templates", ) In my template dir: mylinks/ mylinks/base_site.html mylinks/bookmark_list.html (extends base_site) Now in bookmark_list.html I have to say extends mylinks/base_site.html for it to find everything. If I change the tempalte dir in settings.py to "C:/Python/ my_templates/mylinks" then it looks for the first template in: C:/ Python/my_templates/mylinks/mylinks/ Can someone please tell me a generic structure, or something? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Odd 404 error on Textdrive with Lighty
For prosperities sake I will finish out what was causing the issue. RajeshD pointed out that the media url was being mapped directly to lighty. Which it was. So I moved all static media to a dir called 'static' and removed the line in the lighty vhost that maps media to lighty. Now it all works beautifully. Thanks for the tip RajeshD!

Check to make sure you're defining the __str__(self) on your poll object. That indicates that the object does not know how to turn itself into a string.

There is quite a large difference. Noticing it would depend where you
are using them.
The difference is that ugettext() is a straight function call that
returns the translation result immediately. Executing
s1 = ugettext('redirect')
makes 's1' a Unicode object. It's value will be based on the locale when
it is executed and then never change, no matter what the locale is. So
anything that is executed at *import* time should not be using
ugettext(). Since it's a cause of great confusion for some people about
what when particular lines are executed, I simplified a little in the
docs and wrote "use ugettext_lazy() everywhere", since it's not actually
harmful to do so.
Have a look at the following fragment. Everywhere I am using _(), it is
important to use ugettext_lazy, not ugettext:
class Example(models.Model):
name = models.CharField(_('Your name'), max_length = 100)
class Meta:
verbose_name = _('An example')
Both of those lines are executed at import time. To see this in action,
load a model like this into the Admin interface and view it. Now change
your browser's locale and don't restart anything on the server. Reload
the page. If you are using ugettext() and not the lazy variant, the
displayed string will not change, because the function isn't called
again. If you use ugettext_lazy, the displayed form is locale-aware
(obviously if you are testing this, use some strings that are
translated. I tend to use the string "redirect" a lot, because most
locales have translated that one in Django's core).
This test might need some persistence to replicate if you are using
something like a multi-process web-server since you need to hit the same
piece of code twice -- once to force the first translation and once to
force it to be redisplayed to see the difference. The Django dev server
is ideal for showing the effects, though, since it's single-threaded and
only a single process.
Other places where ugettext_lazy might be reqiured because the code is
executed at import time are default arguments to views and form classes
that you create at the module level somewhere.

Normally, you would be doing the substitution very close to where you
are using the string. At least in the same execution thread and already
in the right locale. So it doesn't typically matter that it now becomes
a Unicode string.
However full generality would be nice. Unfortunately, it's very hard to
make something that understands the '%' operator and returns the right
object so that it will retain it's laziness without breaking other
usages. If you come up with a way to do that, feel free to submit a
patch.
If you really need a case where you need to use ugettext_lazy and apply
a subsitution *and* have it only evaluated much later in another locale
setting, you probably want to investigate the use of
django.utils.functional.lazy(). You give it a function and a return type
(or a number of return types) and it returns something that is only
evaluated when used as one of those return types. This is exactly how
ugettext_lazy() and friends are created. Again, if you come up with
something that might have broad use, submit a patch. Our i18n support is
driven by user requests.
django.utils.translation.string_concat might also be useful in some
cases (we use it internally for a few things): it provides a way to do
the equivalent of ''.join([...]), but evaluated only when needed.

Malcolm

#4165: upload progress in safari
Hello, Has anyone gotten the file upload progress bar from ticket #4165 to work in safari? It works great in IE and FF, but so far no luck on safari.

Re: index page
It really depends on how complicated you want to make it. However using generic views would easily suffice, just set up a dictionary of the objects you need to pass in. Something like: django.views.generic.simple.direct_to_template would do the job.

Make template tags for your various apps, and use them on the index page :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Foreign Key chaining in templates
question.choice.all is wrong :) The default reverse relation name is FOO_set where FOO is the lower- case name of your model. So in your case, it would be question.choice_set.all --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Foreign Key chaining in templates
I am trying to build a simple single page quiz model, with multiple
questions with three classes for quiz,questions and answers, and fourth (not
included) to manage the scores as given below.
class Quiz(models.Model):
name = models.CharField(maxlength=200)
pub_date = models.DateTimeField()
quizmaster = models.ForeignKey(User)
slug = models.SlugField(editable=False)
class Question (models.Model):
quiz = models.ForeignKey(Quiz)
question = models.CharField(maxlength = 300)
answer_explanation = models.TextField()
level = models.CharField(maxlength = 32, choices=levels)
class Choice (models.Model):
question = models.ForeignKey(Question, edit_inline=models.TABULAR,
num_in_admin=5)
answer = models.CharField (maxlength=200, core = True)
is_rightanswer = models.BooleanField()
My question is in Views, how do I display all questions in a single page and
then of course accept the answers, display the right ones, and indicate the
wrong ones and so on.
Since I followed the polls tutorial I managed to display the different
quizzes with the following view
def index(request):
latest_quiz_list = Quiz.objects.all().order_by('-pub_date')[:5]
return render_to_response('quiz1/index.html', {'latest_quiz_list':
latest_quiz_list}, )
However I am unable to display the answers to the different questions.
My detail function in views.py look like this
def detail(request, slug):
p=Quiz.objects.get(slug=slug)
q=Question.objects.filter(quiz=p)
return render_to_response('quiz1/detail.html', {'quiz': p, 'questions':q
} )
Problem is the {% for loop does not accept choices.
{% for choice in questions.choice.all %}
{{ choice.answer }}
{{
choice.answer}}
{% endfor %}
{% endfor %}
I have used the above template in the loop and it does not work.
I know I need to somehow chain each choice to the right question, but I am
unable to.
Thanks in advance
K Mallory

localflavor - UKPostcodeField
Hi I came across localflavors and would like to use the UKPostcodeField for post code validation. However when I try to import this I'm getting ViewDoesNotExist errors. Within my forms.py I'm importing like so: from django.contrib.localflavor.uk.forms import UKPostcodeField I'm then referencing this within the class like so: models.UKPostcodeField() >From here I've also checking within the Django installation on my python path to ensure that this exists. But no joy! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Initial value for a choices field in admin?
Hello, In one of my models I have a choices field: class MyModel(models.Model): units = models.CharField(maxlength=2, choices=UNITS) When I try to create a new instance of this model in the admin, the initial value in the select list for the units field is a dashed line. What I'd like is to be able to define an initial value for this field, and have it already selected in the select list when I just enter the "add object" page. I've tried using the default keyword argument in various ways but to no avail. Googling also didn't help. I would appreciate any ideas.
