Re: How to build manipulator fields in dynamic way?
hi Jaroslaw, I guess you're trying to implement multipage forms. here is the basic ideas: 1. set a 'step' flag in your view function for determine the current step the user is doing 2. use the form manipulator.fields.append(forms.) to dynamically create form's layout base on 'step' 3. while processing to the next step, you could save the form elements' values in two ways as you like: (1) save them in the session/cookie (2) save them by put them into next step form's hidden elements' value 4. in the final step, you do the actual db saving.

How to build manipulator fields in dynamic way?
How to create manipulator fields in more dynamic way? For example I have the form, where only one combobox field is displayed in the begining. After submit, another combobox will be displayed. But its content depends on previous choice... How to do it if I have to define all fields in the constructor? (it is executed only once): class Test(forms.Manipulator): def __init__(self): self.fields = ( forms.SelectField(field_name='first', choices=[(1,1), (2,2)]), forms.SelectField(field_name='second', choices=[what_todo]), ) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Will Complex URLs Slow Things Down?
I'm trying to match emails in my urls.py by doing the following (which
was taken from core.validators:
(?P[A-Z0-9._%-][+A-Z0-9._%-]*@(?:[A-Z0-9-]+\.)+[A-Z]{2,4})
I have a few questions, though.
1. If the url pattern is too complex, will it slow anything down?
2. I'm assuming this matches the url after it has been urldecoded?
3. how do I tell that to re.IGNORECASE?
thanks and I hope that's not too many questions to ask

How to validate CheckboxField?
I am using Django SVN. How to validate tthe form which consists of two
CheckboxField fields. The rule is: the form is validated if ANY of
those fields is checked. My manipulator is:
from django import forms
class TestManipulator(forms.Manipulator):
def __init__(self):
self.fields = (
forms.CheckboxField(field_name='first'),
forms.CheckboxField(field_name='second'),
)
The problem is, I have no access to validators parameter:
forms.CheckboxField(field_name='first', validators=[myvalidator])
because (as I found in django/forms/__init__.py file) the constructor
has only 'field_name' and 'checked_by_default'.
I know that I can use CheckboxSelectMultipleField, e.g.
forms.CheckboxSelectMultipleField(
field_name='options',
choices=[('1', '2'), ('first', 'second')],
validator_list=[validators.isNotEmpty]),
)
but generated html code is not acceptable for me, because I do not want
to have ... list.

Hi Tamara,
I was wondering this the other day. I just tried it and the following worked
for me (from the python command line):
cd /path/to/project/dir
python manage.py shell
from django.contrib.admin.models import LogEntry
logs = LogEntry.objects.all()
len(logs)
dir(logs[0])
logs[0].__dict__
logs[0].action_time
logs[0].action_time.strftime('%Y-%M-%d')
Have fun!
Eric.

Django Google Summer of Code & Merquery
Hi, I just read this post about the Google Summer of Code: http://groups.google.com/group/django-ecommerce/browse_thread/thread/a6af863a3df0f128 I think that post should have been on the django users list. I saw that Google sponsors Merquery - Text Indexing & Search Engine Abstraction Layer for Python by Brian Beck, mentored by Jacob Kaplan-Moss. I've built a search query parser with the Pyparsing module (http://pyparsing.wikispaces.com/), it's included in the Pyparsing examples. It parses user input (with an implicit AND, explicit AND, OR, quotes etc.) into something you can use to calculate the search results (I did this with Python sets, but you could do it anyway you like). If you like it, you can use it ofcourse (BSD license). Cheers, Rudolph --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Tagging app
Hey Luke --
Looks great; I've personally been working on something similar but it
looks like you'll beat me to it :) I've also been slowing adding
generic relationship support, and I'd really like to get a look at your
GenericForeignKey class; chances are it would simplify a good deal of
code I've written.
I am, by the way, +1 on including a standard tagging app
("django.contrib.tags"?) in Django. I think it would be super-user.
Looking forward to seeing your code,
Jacob

Re: I need instructions in best way to use django under IIS shared hosting (Python is installed)

Also, I don't see how the common setup of map .py extension for cgi can help with django (how can execure django/home? how load the settings?) I have FastCGI installed under IIS...

Q behavior with filter() and exclude()
I posted this here to: http://www.djangoproject.com/documentation/db_api/ It seems that when you pass a Q() object into .filter() or .exclude(), you end up with the same results. That is, the context of the method, filter or exclude, is ignored when it receives a Q object. For example: In [1]: from django.db.models import Q In [2]: from django.contrib.auth.models import User In [3]: q = Q(username__exact='dvh') In [4]: User.objects.filter(q) Out[4]: [] In [5]: User.objects.exclude(q) Out[5]: [] In [6]: from django.db.models.query import QNot In [7]: q = QNot(username__exact='dvh') In [8]: User.objects.filter(q) Out[8]: [] In [9]: User.objects.exclude(q) Out[9]: [] (I have a user.username == 'dvh' in an sqlite3 database) I don't know if this is a feature, bug, or quirk, or obvious behavior, but I thought it was worthwhile to post it here as it tripped me up. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: SQL Unions with QuerySets?
Thanks! I ended up seeing that after my original post. I knew I was missing something. Unfortunately that behavior does exactly what you would expect, one query, yielding mixed results. In other words, if I search for 'zo' my results would be ordered ['Bozo', 'Zorro']. I'd like for the results to be more 'relevant'. That is, ['Zorro', 'Bozo'], based on the assumption that people typically search by typing in the beginning of some word. For now I'll end up adding lists together. Not efficient, but it'll be okay in the short term. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Please indulge this newbie > a little. :-) I guess it kind of depends on what type of news sites you mean. The ones I thought you meant were ones built with Django like lawrence.com, which have a lot of programming behind them. There are other Django sites that require less programming, and their are prebuilt modules to help out with that e.g. the 'comments' app in contrib allows you to plug commenting onto a site easily. Have a search for Wilson Miners and Jeff Crofts recent blogs about the things you can do with relatively little programming using Django. Still other news sites (I'm not thinking of Django ones) are built using specialised CMS applications, that come out of the box with a lot of the features you mentioned, with point and click interfaces for turning these things on, but usually at the expense of flexibility, a kind of much of a muchness feel, and sometimes feature bloat that makes it hard to actually do simple things. Picking the right starting point for building your site is really important. To use the analogy of construction work, a pre-built CMS is like a fully built house where all you have to do is do the decorating and move the furniture around. Django is a foundation, some wall sections (and a few complete drop in rooms) and a set of amazing power tools that allow you to build a house in record time. I personally find that the pre-built house style is great until you want to move a wall or or change the wiring, at which point it will be a total pain, whereas Django's approach is ideal for me. However, if you are not really a programmer, the pre-built house style might be more appropriate.

new to django, and have some questions
Greetings, (scroll down to CLIFFNOTES for the short version) Here at my company, we're using python and Zope, though several of the developers have been going on about how great Django is. I'm a systems administrator by profession, and a php/mysql developer who has been toying with dojo as hobby. I have a good understanding of development and programming using various languages like C, Java, Perl, PHP, *nix shell scripting, and a little Windows VB Scripting. I've decided I might go ahead and give Python a try, for a couple a reasons - learn a new language, one which is used here so I can better support our developers - I've got an idea for a large project, that in order to keep it clean I'm going to need to use some sort of framework. I've taken a couple stabs at it in php and repeatedly run into the "code bloat" problem. - As a sysadmin I'm somewhat of a security nazi. I'm one of three people who do the security reviews on our developers here, and generally the main one as I have the most web application building experience. Code built on Django is pretty secure right out of the box from what I've heard. One question I've been trying to get answered before I start messing around with the project is input validation. Specifically html. I'm looking at making heavy use of the Dojo Editor in my project. But there's a lot of html I'm going to want filtered, if not excluded altogether. There's some great tools out the for php that do this, I was wondering what functionality for this sort of thing exists in Django, or is available to plug into Django? I did search google, and google groups for an answer to this but haven't found anything solid, so that's why I am posting here. CLIFFNOTES: - Hobbyist programmer/professions sysadmin looking at giving django a try, with the dojo toolkit, and is curious as to what kind of html input validation tools are currently available for parsing input from the dojo editor. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Templates parameters
Hi djangonauts,
I'd like an advice on the following problem: I try to display a sorted list in
a template, according to GET parameters. I'd like to use the 'dictsort'
filter and the 'reversed' keyword, since I'd like to sort on values created
in the view, which are not present in DB.
Currently, I have:
{% for l in list|dictsort:"name" %}
...
{% endfor %}
I can replace "name" by a variable, but I'd also like to replace 'reversed' by
a variable, to be able to control the sort order from the GET payload.
Is there a way to achieve this? Or another mean to control sort fields and
order from GET for a list?
In a more general way, it would be very convenient to be able to pass
parameters to templates blocks, and to have sort of templates functions: I
often use the same HTML blocks with a slight parameter changing (like class
attribute), and I currently have to duplicate these redundant blocks. Which
seems quite frustrating for a DRY framework. :)
Thanks in advance,

SQL Unions with QuerySets?
I thought I'd post this as I'm not seeing anything obvious in the documentation (that is to say, I cannot /find/ anything, not that it /isn't/ there in an obvious place). I'm making a particular object searchable from my customer UI. I will have a field titled: 'Quick Search' which will search the name and description of the table in question. I'd like the dataset to look like this: filter(name__istartswith=input) UNION filter(name__icontains=input).exclude(name__istartswith=input) if len(input) >= 5: UNION filter(description__istartswith=input) UNION filter(description__icontains=input).exclude(description__istartswith=input) The idea is to make the results somewhat relevant based on the fact that people typically know what something starts with, so that should be first. My approach right now is to do the following (presume logically named query set results): results = list(name_startswith) + list(name_contains) if len(input) >= 5: results += list(description_startswith) + list(description_contains) return results[start:start+pagesize+1] The problem with this is that the full result set is pulled into memory before the final result is used. I know I could be more clever around checking the total result sizes and not continuting, but that seems tricky when you want results 50..60. Is there any way to do sql UNION behavior through the APIs? Or INTERSECT for that matter? Or should I consider dropping into SQL mode and doing my own thing? Are there plans to provide & and | operators on QuerySet objects? It seems like that'd be a pretty big undertaking, but pretty frickin sweet if done well :-D. Anyway, just asking.

Django is not an out-of-the-box CMS - it is a tool for building that kind of web site. You do get the 'admin' interface out of the box, though, and this is very easy to use.

Problems with stepping with the tutorial
Hey,
I just try the tutorial I found on
http://www.djangoproject.com/documentation/tutorial1/. This is what I
do (after installing django from svn):
* create new project
(/usr/lib/python2.3/site-packages/django/bin/django-admin.py
startproject new). It creates a directory 'new', containing the
__init__.py, manage.py, settings.py and urls.py files
* cd to new, and run python manage.py runserver. Just as tutorial
says. Here's what I get:
Traceback (most recent call last):
File "manage.py", line 11, in ?
execute_manager(settings)
File "/usr/lib/python2.3/site-packages/django/core/management.py",

EnvironmentError: Could not import settings 'new.settings' (Is it on
sys.path? Does it have syntax errors?): No module named settings
Seems something very diffrent from what is told in tutorial, and I
didnt done any modifications to the files django-admin have created.
Any ideas what do I do wrong/what should I do now? it's my first
meeting with django, wanna try it and see if it fits my needs.
Cheers, Kender

No problems. My biggest memory hog is MySQL (on the same box), which I should really tune to use less memory. So Apache / Django won't have any problems with memory. The only concern is if you plan to use in-memory caching, and how much memory you plan to give that. Having just read Milton's reply, I should point out my experience only applies to small / medium sites. The biggest site on my box gets 30 000 hits a day.

Re: views
Mary,
If I'm understanding you correctly you can simply use the 'values'
method of the DB-API to query the value of the field for all rows:
>>> from danet.blog.models import Post
>>> Post.objects.values('slug')
[{'slug': 'yet-another-django-blog'}, {'slug':
'fun-at-home-and-zoes-first-birth
day'}, {'slug': 'florida-feb-06'}, {'slug':
'probability-and-expectation'}, {'sl
ug': 'author'}, {'slug': 'sample-article'}, {'slug': 'christmas-2004'},
{'slug':
'letters-to-eli'}, {'slug': 'snow-day-january-2005'}, {'slug':
'favorites'}, {'
slug': 'encrypted-usb-backups'}, {'slug': 'aspnet-2'}, {'slug':
'code-highlighti
ng'}, {'slug': 'multiple-main'}, {'slug': 'strcpy'}, {'slug':
'zoes-arrival'}, {
'slug': 'getting-nia'}]
>>>
This returns a list of dictionaries. You can just extract out the
values with:
>>> x = Post.objects.values('slug')
>>> [d['slug'] for d in x]
['yet-another-django-blog', 'fun-at-home-and-zoes-first-birthday',
'florida-feb-
06', 'probability-and-expectation', 'author', 'sample-article',
'christmas-2004'
, 'letters-to-eli', 'snow-day-january-2005', 'favorites',
'encrypted-usb-backups
', 'aspnet-2', 'code-highlighting', 'multiple-main', 'strcpy',
'zoes-arrival', '
getting-nia']
>>>
If you want to get them in a certain order, or filter them first, then
you can use the 'order_by' and 'filter' methods.

Re: Tagging app
arthur debert wrote: > ps: how is the GenericForeignKey going to work? will it be imported > from the tagging app's package, or will it go into trunk? There is no guarantee that any of this stuff will go into trunk at all - the core django devs would obviously have to be for it first. But the GenericForeignKey class could be usefully part of the ContentTypes contrib app. However, one constraint of my current project is that I have models with string primary keys. I've got a simple 'mapper' system for dealing with this that GenericForeignKey uses, but I'm not sure if it is such a common case that it is worth the extra hassle - for example, the 'comments' contrib app does not handle this case AFAICS. Perhaps GenericForeignKeyInteger and GenericForeignKeyString could both be created - looking at the 'comments' contrib model, GenericForeignKeyInteger could be used to improve it - it would replace (or augment) the get_content_object() getter method with an attribute that handles both setting and getting.

You can do the same thing with my code - a search for a specific text value will return Tags for different types of objects - the 'TagTarget' object and related methods address that specific need. One of the things that motivated my design was the ability to store creation dates - i.e. you can see exactly when you (or anyone else) tagged a specific item with a specific bit of text. Ian's solution goes further, and has various models, including a 'Bookmark' that allows more information to be stored, and other models that store summary information. I think the problem here is analagous to the multiplicity of Python web frameworks - Python/Django makes it so easy! I've chatted with Ian a bit, and while our different approaches cover the same ground, there are reasons I couldn't use his without modification and vice-versa. Perhaps we should set up some pages doing comparisons of the different approaches, including code that can be downloaded. If a clear 'winner' drops out i.e. a solution that will fit a lot of people, it could be suggested that it is put into contrib in Django. But there's no guarantee that will happen in any case, so it would be good to have somewhere central where people can compare and make use of this code. I'll try to tidy something up and release it tonight. It's got a reasonably amount of code doc, and I'll try to add some examples.

404 and 500 erros
