unchecked checkboxes not accessed through request.POST['check_name']
hello all
I am doing a project in Django.
I want to create a list by clicking upon a link, it will open up a new
window using javascript window.open() method.
I have two tables for list.
class Saved_list(models.Model):
description=models.CharField(max_length=100)
number_entries=models.IntegerField()
date_created=models.DateTimeField(auto_now_add=True)
date_modified=models.DateTimeField(auto_now=True)
class Saved_list_entry(models.Model):
saved_list=models.ForeignKey(Saved_list)
date_created=models.DateTimeField(auto_now_add=True)
Onload all entries in the Saved_list is listed with description and
number entries with a check box in front of it.
I want to create new Saved_list. I have done it with a a link.
When any one of the Checkbox is checked I want to increment the
number_entries field and insert a new row in Saved_list_entry.
my view is :
def add_to_list(request):
saved_list=Saved_list.objects.all()
lists=saved_list.values()
if request.method=='POST':
name=''
for lst in lists:
if request.POST[lst['description']]=='On':
name=lst['description']
break
if name!='':
try:
slist1=Saved_list.objects.get
(description=name)
except KeyError:
pass
slist_entry=Saved_list_entry
(saved_list_id=slist1.id)
slist1.number_entries=slist1.number_entries+1;
slist1.save()
else:
slist=Saved_list(description=request.POST
['listname'],number_entries=0)
slist.save()
else:
pass
return render_to_response('candidates/add_to_list.html',
{'list':lists})
and my template is:
{% for l in list %}
{{ l.description }} ({{ l.number_entries }})
{% endfor %}
Save
But i can't retrieve the unchecked checkboxes
please help me..
thanks in advance

avoid cascade delete
I have two models, links and groups. A Link has an optional foreign key Group. When I delete a Group, Django by default deletes all Links that referenced the Group that is being deleted. How do I avoid the default behavior that does a cascade delete. Of course I could use the cursor but would am hoping there is some option I don't know of for delete(). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Best way for making a "Poll"?
First of all, I know the tutorial supplies somewhat of a poll, and I've been through it. What I want to do is make an app that has one poll (or question) of the day that someone can edit from the admin interface. Each question has 4 choices. Also, there will not be user registration, just a field to input your name. I also want to use ModelForm. Now, should I have each question have a ManyToMany with choices, or each choice have a ForeignKey with a question? Initially I thought a ManyToMany would be good since its widget is multiple choice field in ModelForm. But, it also showed up as a multiple choice (with no choices yet!) in the admin interface. So I decided to go with the way the tutorial had it setup, but I got some error about a missing column when I tried to save a choice. (I'm using sqlite3 and the SVN version) It also did that when I tried to have it stacked inline with question. I tried flushing, resyncing the db, and using django-evolution (after it didn't work). So I'm deciding to start all over. How can I get choices, a CharField I guess, to show up as radio select widgets in a form? Also, at the bottom of the page I want to show each (in standard text) Question of the day and its choices. I'm assuming that's just simply reading CharFields and displaying them? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: djangobook ch3, can't see the view current_datetime
You were right, Django didn't see any URLs in the URLconf file because
I wasn't using the right one. I had another site also called
'testproject' in a different directory (deleted now). So I was using
views.py and settings.py in the /web/django directory, but the urls.py
from a totally different one. It was subtle, and I'm glad I caught it
sooner than later. All is working fine now with this urls.py when
accessing http://localhost:8080/testproject/time
from django.conf.urls.defaults import *
from testproject.views import current_datetime
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()
urlpatterns = patterns('',
(r'^time/$', current_datetime),
# Example:
# (r'^testproject/', include('testproject.foo.urls')),
# Uncomment the admin/doc line below and add
'django.contrib.admindocs'
# to INSTALLED_APPS to enable admin documentation:
# (r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
# (r'^admin/(.*)', admin.site.root),
)
Thanks again.

cascading drop down lists
Hi. I am creating a separate admin page than the built in one. This new admin site is meant to scrape data from my university's course catalog based on a given set of criteria. I want to use a series of drop down lists to define this criteria. For example, I want to first have to select the year. Then I hit submit and the form is processed on the same page. Then the next drop down list will become populated with a list of seasons associated with that year. Submit. Then the next drop down list will become populated with departments associated with that season and year. Submit. The next list is filled with courses associated with with that year, season, and department. I hope this gives you the right idea. Do I have to create a form model to do this? Is there any other way to retrieve POST data? If I must make a model, what are your suggestions for the best way to go about this? Thank you very much and any help would be greatly appreciated. -Alan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Since Django supports everything from Python 2.3 to 2.6, plus Jython, PyPy and IronPython (in theory), we've got a few hairy corners. There's been a few threads on django-developers about a patch that could make Django run through 2to3.py more or less, as of a few months back. We'll probably do something about that once Python 3 is released, but I wager (not too much, though) it's unlikely that on day 1 of Python 3.0 being released Django will work straight out of subversion. It's going to be a miniscule portion of the total userbase, after all.

djangobook ch3, can't see the view current_datetime
I'm a new user to Django, hi everyone.
My system:
Windows XP
Python 2.5
Apache 2.2
>>configured for mod_wsgi
MySQL, MySQLdb #Irrelevant at this point
My issue:
Having trouble getting the through the first example. Basically, when
directing the browser to '.../time/' I'm still at the 'It worked!'
beginning page. I haven't been able to bring up the view with
current_datetime.
Some things you might ask to know:
- For Apache:
WSGIScriptAlias /testproject "C:/web/django/apache/django.wsgi"
Order allow,deny
Allow from all
- For my app:
## django.wsgi
import os, sys
sys.path.append('C:/web/django')
os.environ['DJANGO_SETTINGS_MODULE'] = 'testproject.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
## views.py
from django.http import HttpResponse
import datetime
def current_datetime(request):
now = datetime.datetime.now()
html = "It is now %s." % now
return HttpResponse(html)
## urls.py
from django.conf.urls.defaults import *
from testproject.views import current_datetime
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()
urlpatterns = patterns('',
(r'^testproject/time/$', current_datetime),
# Example:
# (r'^testproject/', include('testproject.foo.urls')),
# Uncomment the admin/doc line below and add
'django.contrib.admindocs'
# to INSTALLED_APPS to enable admin documentation:
# (r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
# (r'^admin/(.*)', admin.site.root),
)
When entering http://localhost:8080/testproject/time I'm reading this
in the Apache error log:
[Sun Nov 16 17:27:37 2008] [info] mod_wsgi (pid=1768): Create
interpreter 'ADAMYEE.gateway.2wire.net:8080|/testproject'.
[Sun Nov 16 17:27:37 2008] [info] [client 127.0.0.1] mod_wsgi
(pid=1768, process='', application='ADAMYEE.gateway.2wire.net:8080|/
testproject'): Loading WSGI script 'C:/web/django/apache/django.wsgi'.
http://localhost:8080/testproject/time just brings up 'It worked!'
Notice how it shows the process as just /testproject and not /
testproject/time. Is this supposed to be that way? Is there
something I'm missing in the 'testproject.settings.py' that is
preventing me from seeing the /time URL? I think everything is setup
correctly. I've spent a little time looking for an issue related to
this, but couldn't find a post. Does anybody have any suggestions?
Thanks.

Re: Caching and I18n
Hello Ramiro,
thanks for your reply. According to the docs, the Locale and Session
middlewares should set the Vary-On headers accordingly, and indeed
they are:

Server: WSGIServer/0.1 Python/2.5.2
Vary: Accept-Language, Cookie
Content-Type: text/html; charset=utf-8
Content-Language: de
200 OK
I'm lost. Maybe Beegee from the other thread found a solution in the
meantime.

A lot of times a "pure Python" module or package can be simply installed just by dropping it into a directory that's already on the installer's Python path, but if you have requirements for data files to land in a particular spot or of C code needs to be compiled to provide an extension module then setup.py can be invaluable.

Re: populating database model with form model
thanks for trying to help.
app engine models use .put() instead of .save() and according to
guido, there is very little difference between the two.
I have pasted models.py and search.py so you can see the two. maybe
that will help.
paste url: http://dpaste.com/91258/
the django app i'm bulding here is suppose to be an "orbitz
equivalent" for my software engineering class. we chose to use django
and app engine for the free hosting and a chance to use something we
had only read about (django).

Re: general problems with installing downloaded django apps
Thanks Steve. That moves me forward. I'll read about module packages in my python book. I think what I'm discovering is that I've gotten somewhat deep into Django without really understanding some of the underlying python concepts. What is the point of setup.py files, if they are not really necessary for installing apps? I see that the tagging app gives me the option to install using setup.py, but it's not required. -Ryan On Nov 16, 2:35 pm, Steve Holden <[EMAIL PROTECTED]> wrote: > webcomm wrote: > > [Please don't top-post ...

Saving associated data with multiple formset_factory
Hey there, The last Django application I worked on was in 0.96 and I'm trying to get used to the new stuff in there. I've been following the docs here: http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#id2 trying to use the formset_factory on some forms. I have a Contact model, and associated through a FK it has several ContactNumber and ContactEmail instances. I've used ModelForm to create the forms and it works successfully if I just have one instance of the number and email, but when I try to create a formset for it, I get this problem: 'ContactNumberFormFormSet' object has no attribute 'save' But as far as I can see, I've followed the docs correctly?? I've pasted the code for my model, form and view below: Contact,ContactNumber,ContactEmail models: http://paste.ifies.org/158 Forms: http://paste.ifies.org/161 View: http://paste.ifies.org/160 Any help on this would be appreciated Tane --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

The user's language preference might end being stored (and sent back) in
the django language preferences cookie or the session-related cookie.
So, to cover all the possible channels that preference could come in,
you will also need to indicate 'cookie', in the Vary header:
@vary_on_headers(''Accept-Language', 'Cookie')

I don't know anything about Google App Engine, except that it manages
models differently from normal Django. All I can say is that in
standard Django, your two MyModel calls above do exactly the same
thing: create a new model instance with the values you pass, then
immediately throw it away. It won't be saved to the database, because
you're not telling it to be.
You would need to do something like:
new_obj = MyModel(field_name='value')
new_obj.save()
For your other problems, you'll need to give more details. Preferably,
post your code on dpaste.com and post a link here.

How to deal with NTLM authentication
I have a website outside of django that uses NTLM authentication, requires username and pass to be entered before access to the site is allowed.

populating database model with form model
Hi, i wasn't sure whether i should ask this here or on the google app
engine list.
I really have two problems. The first is, if i have a form that i
populate choices in a choicefield using entries in the database, it
only updates once. Every time after the first time it just uses the
same vales it found before, even if i go add more items to the
dateabase. I have tried deleting all browser cache.
I have a datastore model (reason for being unsure) that i am trying to
load with information submitted through a django model form. For a
long time, when i would submit the form i would get an error
initialize the datastore model using named arguments in the
constructor. it would say:
'unicode' object has no attribute 'is_saved'
I would send these values using:
form = SearchForm(request.POST)
MyModel(
field_name = form.cleaned_data.get('field_name', 'default'),
bool_field_name = form.cleaned_data.get('bool_field_name', False)
)
I would get this error even if i tried to pass values directly, like:
MyModel(field_name="value", bool_field_name=True)
Lately, though, the page has just been always failing when checking
is_valid() on the form. (always returns False)
I am a fairly novice django user, and a fairly novice app engine user.
I have read the djangobook many times, and i have googled this problem
to death. If anyone has any suggestions or advice or anything that
might help me, please reply. I would greatly appreciate it.

There are no restriction (by Django) on where apps are installed, as long as their base directories end up on sys.path[]. Some apps have their own templates with them (typically extending some notional basic template called "base.html", some apps expect you to provide templates. In the former case you can pick them up by having 'django.template.loaders.app_directories.load_template_source' in your settings.TEMPLATE_LOADERS, in the latter case you can put the templates pretty much wherever you want. regards Steve -- Steve Holden+1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Intercepting return from new ForeignKey popups? (RelatedObjectLookups.js)
I've been experimenting with an autocomplete widget for ForeignKey model fields following the very useful advice from Jannis here: http://jannisleidel.com/2008/11/autocomplete-form-widget-foreignkey-model-fields/ The basic idea is to create a widget with a hidden text field that contains the ForeignKey ID that is updated by the results of the autocomplete field. I've got everything working correctly except for one problem. When adding a new foreign key by clicking on the "+" the hidden field is correctly updated with the primary key of the new object, but the autocomplete field still shows the previous text which is confusing to the user. The insertion still works correctly of course as it's the hidden field that is actually used. Any ideas on how to correct this? It seems the JavaScript code RelatedObjectLookups.js controls this behavior, but I can't quite get my head around what to do. I need someway to intercept the return from the Popup to update fields on my form.

object_create generic view, how to deal with hidden field in my model?
Hi django users, Currently writing an application in Django, I'm trying to use most of the super-powered tools that Django provide. One of them is generic views. Use of object_list and object_detail works well, even with more complex queries which I implement using a 'wrapper' view. But now I'm blocked with object_create generic view, and can't find a way to solve it. My model is composed of several fields, some of them (creation_author and creation_datetime) are not showed on the creation form because they are not supposed to be editable by the application user. It looks like this (simplified) class Model(models.Model): name = models.CharField(max_length=100) description = models.TextField() creation_author = models.ForeignKey(User, related_name='%(class)s_creation_author') creation_datetime = models.DateTimeField(editable=False) To fill the creation_datetime field, I have created a save() method directly in my models.py field and I think it should works. My problem is with the creation_author field. How can i fill it using the generic view? Because in my model save() method I have no conscience of the user logged in, so I can't fill this field there. ps : I'm not really sure my problem is there, but I think so... -- Eric Veiras Galisson http://www.veiras.info --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Model Formset Factory
When using a modelform on its own, I see that overriding __init__() enables the customization of generated forms. Is it possible to customize each of the modelforms (say changing the widgets on some of the form fields, adding/removing a field, etc.) in a modelformset when using modelformset_factory? The same customization may be applied to all forms in the formset (based on requesting user perhaps), or to only some of the forms (based on the initial modelform data or related data). If so, how would you go about doing this? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

general problems with installing downloaded django apps
I am fairly new to python and Django. I have no problem setting up my own apps by following the tutorial. However, I *always* have problems setting up someone else's apps. I think I've tried installing 5 apps that I've downloaded from code.google.com and elsewhere, and have been unsuccessful every time. I think my problems in some cases have to do with not understanding how paths work in Django. The directory structure seems to be pretty loose. There don't seem to be conventions about where to put things, at least none that are spelled out... unless there's some documentation I'm missing (quite possible!). I feel like I need some general primer on where to upload things. For example, I've been putting my own apps in a directory called myproject. I understand that I can call that directory whatever I want as long as I referenced it the right way in the py files. But I would think that I would also put other downloaded apps in that same directory... but I'm finding (I think) that when I install someone else's app, it needs to go alongside that directory and not inside that directory. I'm hoping that someone reading this will be able to see what the gap is in my knowledge... what is the concept I'm not understanding here?

use the content_object field of the comment like this:

content_object is a foreign key to the original object so in my case

POP before SMTP authentication in Django while avoiding that the server mail goes to users' spam folder
I have recently started a new Django website, www.darela.com, and I have some problems with sending automatic mails. This is a community website, where consultants, contractors and other specialists can present themselves, publish their profiles and describe their skills and experience, publish technical articles, discuss news, participate in discussion boards etc. During registration, users recieve token-based email confirmation and are asked to verify their accounts. There is also an internal messaging systems (between users) where messages are forwarded to users email address, and several other cases where email are sent automatically by the server. Registration confirmation mails, for example, are sent from [EMAIL PROTECTED], however, they almost invariably go directly to user's spam folder. I know that there are many reasons why a legitimate message can be considered spam, including the content, discrepancy with reverse DNS, blacklists etc... However, if I configure Outlook to use this address ([EMAIL PROTECTED]) and send an identical message to the same user, it will go through to user's mailbox and will not get to spam folder - even when users have Yahoo or Hotmail account. I am sending these messages using smtplib. I am not using Django's send_mail because my mail server requires POP before SMTP authentication - and I am not aware of how to have this in Django - so I am using a modified version: def send_mail(subject='', text='', sender='', to=''): M = poplib.POP3(settings.EMAIL_HOST) M.user(settings.EMAIL_HOST_USER) M.pass_(settings.EMAIL_HOST_PASSWORD) headers = "From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n" % (sender, to, subject) message = headers + text mailServer = smtplib.SMTP(settings.EMAIL_HOST) mailServer.sendmail(sender, to, message) mailServer.quit() Before I start trying to insert the same headers as in Outlook, I was wondering if someone had a similar problem before? Does anyone know another way to achieve pop-before-smtp with Django? Or what else can I do to avoid these messages ending up in spam folders? Any ideas?

Re: Post/redirect/get pattern for file upload with confirmation
Accidentally posted the first reply and you already beat me to my actual reply, wow. The "not feeling right" part meant to imply that the disadvantages I could see for both made me wonder if there wasn't another (and better) option available, but based on your answer it seems that won't happen anytime soon.

[django1.0+comment framewok ]how can i get the object comments are attached to after post?
Hi everyone, i am now using Django’s comments framework, accoring to the book , after end user post the comment, we can create our own template comments/posted.html, and this template has a variable called object that refers to the object that received the comment. But i cannot get this object in the template, i am not sure it's old version feature or not. Any help and hints are appreciated!

Caching and I18n
Hello everyone,
I'm trying to implement caching for my bilingual site. The problem is
that once I enable caching and I change the language (via the example
code in
http://docs.djangoproject.com/en/dev/topics/i18n/?from=olddocs#the-set-language-redirect-view
), the page does not change. The Content-Language header that the
browser receives is indeed changed accordingly, but apparently the
caching system is not aware of the change.
I've set up my middleware as follows:
MIDDLEWARE_CLASSES = (
'django.middleware.cache.UpdateCacheMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware', # muss vor
auth
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.middleware.locale.LocaleMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.cache.FetchFromCacheMiddleware',
)
I also tried per-site caching (disabling caching in the middleware),
but did get the same results, even when I specified vary_on_headers
('Content-Language','Accept-Language').
I have found a snippet (http://www.djangosnippets.org/snippets/443/)
that might work, but I'm reluctant to use this hack and also rely on
the deprecated CacheMiddleware.
Any help and hints are appreciated!
Thanks,
Maik
PS. relevant settings.py excerpt:
CACHE_BACKEND = 'locmem:///'
CACHE_MIDDLEWARE_SECONDS = 300
CACHE_MIDDLEWARE_KEY_PREFIX = ''
CACHE_MIDDLEWARE_ANONYMOUS_ONLY = True

Re: Post/redirect/get pattern for file upload with confirmation
Hi Malcolm, thanks for the fast reply. What is the downside of sticking this kind of information into a session, just that the session backend needs to carry this amount of information around and cookies have to be enabled for it to work? I otherwise would prefer it over (2) just for the cleaner URL.

Then you're going to have provide more information about what would "feel right", since both those approaches are technically valid and common to boot. The second one is basically the canonical way to do it for the REST style of architecture. The exact form of the URL is a design issue -- it doesn't have to use a querystring, after all -- but the naming of a resource to do conditional data display is standard. Since you've nixed the two standard ways to do this, aren't you rapidly running out of choices? You don't want to store the information in the session (which is the only really transient way to move data between requests that doesn't go via the URL) and you don't want to create a new identifiable URL for the new resource. It seems like we're reduced to using The Force to convey the information at that point. That's not supported in Python yet.

I suspect you're actually asking the wrong question. The question isn't "where should I redirect to?", but rather "how can I tell when loading the file listing page, after a GET request, that some extra information about the renamed file and notified people should be displayed?". It doesn't matter what URL you actually retrieve after the file is uploaded, that question still remains -- how to tell that you need to display that information. Once you've solved that problem, redirecting the the normal file listing page is quite a natural place to go, since it shows the file listing (plus this extra information sometimes), but that's really a side-issue. You have at least a couple of choices: (1) Use sessions and store the fact that a file was just uploaded (and renamed) and the list of people notified in a key in the session. When the user accesses the directory listing page using GET and if they have that session key, display the extra information and then remove it from the session (so it's displayed only once). Or possibly you want to keep it in the session for a period of time or something. In any case, you can use the session. (2) The more HTTP/REST-like approach is to come up with a unique identifier for the page that displays the newly uploaded information. This identifier tells you (the webserver side of the code) that you need to display the new filename and list of notified people. One way to do this is to add a parameter to the GET request that is, say, the primary key (or some other token) of the newly uploaded file. Then, when you are processing that page, if the querystring contains that parameter, you retrieve the new filename and the list of people who would have been notified from the database. The second way uses the fact that you can attach a querystring to a URL and that's quite valid for an HTTP redirect. It's also probably not that hard to implement, providing you can easily determine from the id of the file who the recipients were. The slight drawback is that anybody who knows that URL can view the same information. Maybe that's not a problem. If it is, you can use access checking (e.g. the special display information is only presented if the currently logged in user is the person who uploaded the file with that id). Thus the 'normal' view is, say, /foo/file_listing/ and the target after an upload is, say, /foo/file_listing/?upload=123. The first of these two choices is pretty fast to implement, but puts information in the session, which you may or may not like doing. The second is more "natural" in a way, but you have to do some work to process the incoming optional querystring. It's still not particularly hard, though.

Post/redirect/get pattern for file upload with confirmation
Hi, I am confused on how to best use the post/redirect/get pattern for the following problem: Part of the application I am writing is a basic file manager, i.e. it lists directory contents to users and lets users download files or upload a file to the directory. Upon upload the file is renamed (to include date and user) and then saved to disk, users that need to be informed receive an email that a new file was uploaded. My basic idea would be to use the same URL and view/template for getting the directory listing and posting a file for uploading to it. If a file is uploaded successfully the renamed file name and the users that received the email should be listed in a notification part of the template (i.e. ...) which confirms to the user that everything is ok. Now I am stuck on how to best do this. POST/REDIRECT/GET does not seem to fit here, since HttpResponseRedirect cannot pass any parameters to a template and redirecting to the same URL does not make sense anyway. What other pattern could/should I use? Right now I am just doing a render_to_response with the same template, regardless of whether it is a first GET of the page or the POST for the file upload. Of course this means once a file was uploaded and the notification is displayed any refresh of the will give you a browser warning about resending data which I would like to avoid. Any suggestions?

Re: How to create a form with dynamic number of fields?
I've recently had a situation where I needed to create dynamic forms
and corresponding code to handle them.
One thing that you should know about python is that there's nothing
special about classes, you can take a collection of attributes and
methods and use them to create a new class on-the-fly using python's
type() function. You can use this to dynamically build a form class
with a new field.
My roommate wrote a great blog post on how to do build classes
dynamically (http://askawizard.blogspot.com/2008/09/metaclasses-python-
saga-part-4_30.html), which you should read before attempting this.
Once you understand what that is talking about (or not), you end up
writing some code like this:
If you want this form to be dynamic:
class MyDynamicForm(Form):
foo = CharField(max_len = 100)
bar = IntegerField()
def clean_foo(self):
value = self.cleaned_data['foo']
if value != 'foo':
raise ValidationError('foo is not foo!')
def clean_bar(self):
value = self.cleaned_data['bar']
if value != 42:
raise ValidationError('wrong answer')
You could build it programatically with:
# Our base classes (which you could build programatically if you
wanted)
bases = (Form,)
# Our class attributes
attys = {
'foo' : CharField(max_len = 100),
'bar' : IntegerField(),
}
# This returns a clean method built from some parameters
def general_clean(name, correct_value, error_text):
def inner(self):
value = self.cleaned_data[name]
if value != correct_value:
raise ValidationError(error_text)
return inner
# Now add the clean methods. You could just define methods and assign,
but this illustrates generating them programatically.
for name, correct_value, error_text in (
('foo', 'foo', 'foo is not foo!'),
('bar', 42, 'wrong answer'),
):
attys['clean_' + name] = general_clean(name, correct_value,
error_text)
# Now, to create the dynamic class, you need the following
incantation:
DynamicForm = getattr(Form, '__metaclass__', type)('DynamicForm',
bases, attys)
# That only creates the *class*, we still have to create an instance
form = DynamicForm({'foo': 'foo', 'bar': 42})
Does this help? It would let you dynamically add elements and handlers
to the form that django is aware of, thus you get all the benefits of
using the form framework. Let me know if this is a bit thick and I'll
be happy to explain it and perhaps blog a more coherent example.

dynamically (http://askawizard.blogspot.com/2008/09/metaclasses-python-
saga-part-4_30.html), which you should read before attempting this.
Once you understand what that is talking about (or not), you end up
writing some code like this:
If you want this form to be dynamic:
class MyDynamicForm(Form):
foo = CharField(max_len = 100)
bar = IntegerField()
def clean_foo(self):
value = self.cleaned_data['foo']
if value != 'foo':
raise ValidationError('foo is not foo!')
def clean_bar(self):
value = self.cleaned_data['bar']
if value != 42:
raise ValidationError('wrong answer')
You could build it programatically with:
# Our base classes (which you could build programatically if you
wanted)
bases = (Form,)
# Our class attributes
attys = {
'foo' : CharField(max_len = 100),
'bar' : IntegerField(),
}
# This returns a clean method built from some parameters
def general_clean(name, correct_value, error_text):
def inner(self):
value = self.cleaned_data[name]
if value != correct_value:
raise ValidationError(error_text)
return inner
# Now add the clean methods. You could just define methods and assign,
but this illustrates generating them programatically.
for name, correct_value, error_text in (
('foo', 'foo', 'foo is not foo!'),
('bar', 42, 'wrong answer'),
):
attys['clean_' + name] = general_clean(name, correct_value,
error_text)
# Now, to create the dynamic class, you need the following
incantation:
DynamicForm = getattr(Form, '__metaclass__', type)('DynamicForm',
bases, attys)
# That only creates the *class*, we still have to create an instance
form = DynamicForm({'foo': 'foo', 'bar': 42})
Does this help? It would let you dynamically add elements and handlers
to the form that django is aware of, thus you get all the benefits of
using the form framework. Let me know if this is a bit thick and I'll
be happy to explain it and perhaps blog a more coherent example.
