That's because c.category_set is a manager object describing a _set_ of categories.

Django _does_ support multiple levels of relations, in both the object structure and the query language - you just have to keep a careful track of when you have an object, and when you have a list of objects.

How to change the representation of newline?
When I input some text with newline characters in TextField under admin page, I found that the newline character in database is represented as \r\n. My django site is running at linux, other program under linux always treat newline as \n. This cause some compatible problems.

newforms: MultipleChoiceField with CheckboxSelectMultiple
I'm toying around with converting my forms over to newforms and have
come across a problem which may be just user error.
I have a form:
class AddForm(Form):
flags = MultipleChoiceField(choices=[("A", "Aquatic"), ("C",
"Canopy")])
I have a view, which for the moment, is just trying to redisplay the
contents of the form:
def view(request):
form = AddForm(request.POST)
return render_to_response("test.html", {"form": form})
The problem is coming from request.POST. It doesn't handle same-named
fields. The data is there in request.raw_post_data.
This worked before when the checkbox fields had unique names, but now
they all have identical names.
Am I approaching this wrong?

Nested Relationships between tables in Django Database API
Hi All, Just curious, does the Django Database API support nested relationships more than one level deep? It's starting to look like it doesn't... for example, let's say I have three tables: Contest, Categories, and Finalists; related as such: Contest, Category foreign keys to Contest, Finalist foreign keys to Category (a nested relationship). Let's continue with the example of a "talent contest": A (Contest) contains the actual contest details (date and time it occurred, judges, a description, location, etc.) B (Category) contains the contest's associated categories (juggling, music, tight-rope-walking, etc.) C (Finalist) contains the finalists for each category (1st place, 2nd place, 3rd place). As you can see, table C is related to A, but only indirectly via B (hence the nested relation). Here is an extremely simplified model for the purpose of illustration: class Contest(models.Model): name = models.CharField(maxlength=100) def __str__(self): return "Contest: %s" % self.name class Admin: pass class Category(models.Model): name = models.CharField(maxlength=100) contest = models.ForeignKey(Contest) def __str__(self): return self.name class Finalist(models.Model): name = models.CharField(maxlength=100) category = models.ForeignKey(Category) def __str__(self): return self.name In the console, if I populate the Contest, the instance produces a "category_set" method/property (as expected and documented). However, if you "dir(c.category_set)" there is no "finalist_set" method/ property in the category_set's namespace... So, am I correct in surmising that the current implementation of the ORM will not currently work with this type of DB model (2 level indirection)? Is there a workaround? Any thoughts or suggestions are most welcome. Hopefully all of this makes sense... thanks in advance, -D --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

forms and one-to-many relationships
I'm trying to create a simple invoice application where an Invoice has (0..n) LineItems. I've created form that contains a few entries for line items, and using the standard AddManipulator I'm able to save a new invoice and its line items to the database. But I would like to add some code that performs a few calculations before the new objects are saved to the database: 1. for each LineItem, compute extended = quantity * unit_price 2. Invoice.subtotal = sum(LineItem.extended) 3. Invoice.taxAmount = sum(LineItem.extended if LineItem.isTaxable) * taxRate 4. Invoice.total = Invoice.subtotal + Invoice.taxAmount Writing recalc methods that perform these operations on the model objects is pretty simple, but how can I invoke such logic before the objects are actually saved in the database? Overriding save() in the model class doesn't work because db.models.manipulators.AutomaticManipulator.save() creates and saves the parent (Invoice) before creating the related children (LineItem). Is there a method to extract a new instance of a model object from the POST data without calling save()?

Newforms and composite widgets
One of the things I was hoping for in newforms but haven't found is a way to do a composite form field that uses multiple elements that reduce to a single python object. E.g., >>> class MyForm(Form): ... postdate = CompositeField(ChoiceField(choices=['Jan', ...]), ... ChoiceField(choices=range(1,32)), ... ChoiceField(choices=range(2000,2010))) ... >>> str(MyForm()) 'PostdateJan' (and so forth, with select fields for all three before closing the td/tr)) If clean() were called on my hypothetical composite field above, it would return a single datetime object.

In addition, he should remove the leading '/' from the path in the
extends clause. If you code a leading slash, os.path.join() ignores
the template path.

In my experience, text can get broken on each and every step. First, I would try to see whether the browser sends it correctly using a dumping HTTP proxy (netcat or a simple perl script). Then, check whether it is written correctly to the database (e.g., issue a SELECT in mysql). Then, see if it is displayed correctly.

I assume mysite is the project you've created under c:\temp using
"django-admin.py startproject mysite". To use the shell, you need to
have the following environment variables set:
PYTHONPATH = c:/temp
DJANGO_SETTINGS_MODULE = mysite.settings
I haven't tested this, so you may have to play with the PYTHONPATH
format (slashes, etc.).

sys.path.append affects only the process it is called in. Setting
PYTHONPATH should work for you.

problem with django settings module
I am following the tutorials from the Dajngo book. At chapter four, i
am first getting the following error after runnning
>>>from django.template import Template
in the python shell.
environment variable DJANGO_SETTINGS_MODULE undefined
Next i tried to fix this by adding a Windows system variable:
variable: DJANGO_SETTINGS_MODULE
path: c:/temp/mysite (this is where my project lives)
Now after running the above command I get the following errors:
raise EnvironmentError, "Could not import settings '%s' (Is it on
sys.path? Does it have syntax errors?): %s" % (self.SETTINGS_MODULE, e)
EnvironmentError: Could not import settings 'c:\temp\mysite' (Is it on
sys.path? Does it have syntax errors?): No module named c:\temp\mysite
I tried adding the path to mysite to the sys.path of python.
>>>import sys
>>>sys.path.append('c:/temp/mysite')
This appends the directory to sys.path, but it does not save it I to
the path module I guess. The next time I imported sys, it was gone
again. How do I do this. Will it solve my problem?
Thx

Re: is there a way to combine generic views?
>> I want a page which displays both the details of an object and the list of
>> the objects.
Really important question: is the object you want the details of
related to the list of objects, via a ForeignKey or ManyToManyField?
Because if so, you don't need to do any view combination at all. (Of
course, if they are unrelated, everything everyone else said about
extending generic views is dead on).
One thing that no one here has mentioned, and which the documentation
also does a poor job of mentioning (presumably because it explains
models before it explains templates, and thus doesn't want to get in to
template details when it explains model realtionships) is that if you
define relationships between objects, you can access related objects in
templates. For instance, let's say you have these models:
class UL(models.Model):
pass
class LI(models.Model):
UL = models.ForeignKey(UL)
name = models.TextField()
Using the object detail generic view on UL will give you an "object"
variable in your template for the given UL. This variable will have an
attribute (my terminology may be a little off here, but I'm too lazy to
look up the correct phrase, so just look at my examples if you're
confused): "li_set". This attribute in turn has two attributes: "all",
and "count". You can use these attributes to access the related LI's.
For instance, using:
{{ object.li_set.count }}
in your template will return the number of LI objects that have a
foreign key of this particular UL object's ID. Similarly, using:
{% for li in object.li_set.all %}
{{ li.name }}
{% endfor %}
will return the names of all of the LI's associated with this
particular UL object.
Hope that helps.

M2M - 'backward' relationship
In the API documentation it says:
Many-to-many relationships
"Both ends of a many-to-many relationship get automatic API access to
the other end. The API works just as a "backward" one-to-many
relationship.
The only difference is in the attribute naming: The model that defines
the ManyToManyField uses the attribute name of that field itself,
whereas the "reverse" model uses the lowercased model name of the
original model, plus '_set' (just like reverse one-to-many
relationships)."
Problem is, the examples it goes on to give of all the things that you
can do with a M2M model need more knowledge of Python than I have. So
can somebody point me in the right direction?
Here are my models(abbreviated):
class Category (models.Model):
category = models.CharField (maxlength = 100)

def get_absolute_url(self):
return self.slug
Now, using the category_list and/or category_detail GENERIC templates,
what on earth do I put in to return a list of Organisations by
Category?

can see I'm getting somewhere...)

How to restrict, in "delete confirmation", the affected objects list?
Is it possible to restrict the list of "would be deleted" objects when asking to delete a specific object using the admin interface? I have several thousand records related to the object to be deleted. Is is quite useless (and time consuming) to display the list of 3000+ records to ask for confirmation. It would suffice to just say "and other 3000+ objects of type XXX will be deleted... want confirm?" Even if I change the delete_confirmation form and comment-out the "deleted_objects|unordered_list" the Django admin interface takes a lot of time to read the "would-be-deleted" records. Does anyone know if there's an easy out-of-the-box way of doing it? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

model problem "matching query does not exist"
After solving a problem described at:
http://groups-beta.google.com/group/django-users/browse_frm/thread/b453f0c91e29cc04?hl=nl
I continued developping my model. Unfortunately a new problem arose.
Given the following model, I get an error message in admin after
successfully saving an article and then selecting it.
MenuItem matching query does not exist.
The model describes an article 1to1 to menuitem
and a menuitem Mt1 to itself.
This way I try to get some kind of menustructure.
What causes the problem?

Re: Cannot resolve keyword 'caption' into field
After many many trail and error I maybe found a 'bug'.
I simplefied the above model till it worked again. Then I added the
next field option and the error arose.
"unique=True" in MenuItem > name
Complete simplefied model with error:
###
from django.db import models
class Article(models.Model):
headline = models.CharField(maxlength=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
published = models.BooleanField()
def __str__(self):
return self.headline
class Admin:
pass
class MenuItem (models.Model):
article = models.OneToOneField(Article, edit_inline=models.TABULAR,
num_in_admin=1)
naam = models.CharField(maxlength=200, unique=True, core=True)
def __str__(self):
return self.caption
replace
naam = models.CharField(maxlength=200, unique=True, core=True)
with
naam = models.CharField(maxlength=200, core=True)
and it works again.

gotapi.com - python there, no django (yet)
http://www.gotapi.com/ - very neat, lots of APIs to go through (HTML, Javascript etc) and now including python. No django as yet. :( However, you can't download copies of XML formats to see how others have done it (eg python).
