Re: django apps that implement ticket filtering?
Yeah, I just thought maybe I could leverage some existing code that would support AND and OR of filters and provide an interface where the user can add filters as needed. It seems to me that creating an interface where you AND and OR filters is not so simple. But that's not really a django issue - just thought someone here might have some ideas.

rollback transaction without an exception when transaction is tied to http requests

I have an app which I have been planning to release from about january 2007. The app has been ready since then, but I have not formally released it because I was doing the minimalist thingie. I now realise that this goes against the open source creed - commit early and commit often. By putting it up as it is, user feedback is there, people will fork and the work will get done. (and also if the app is useless, then no one will respond and I can save time). So I suggest you just publish it and take it from there. -- regards kg http://lawgon.livejournal.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Global objects
Let me explain myself better: I have some menus in my site, and they appear all along the front-end pages. One of these menus must have a list of objects.

Trouble rendering a ManyToManyField with CheckBoxSelectMultiple widget
I am rendering a ManyToManyField with a CheckboxSelectMultiple widget like so: class CreateBandForm(ModelForm): styles= forms.ChoiceField(widget=forms.CheckboxSelectMultiple(), choices=[(i,i) for i in Style.objects.all()]) class Meta: model = Band fields = ['name','styles'] This renders fine, but when I select a few choices (say 'latin american' and 'rhythm and blues') and submit the form, I get the following validation error: Select a valid choice. [u'latin american', u'rhythm and blues'] is not one of the available choices. I have tried various permutations for "choices", including choices= [(i.id,i) for i in Estilo.objects.all()], with no luck so far.

Weird transaction issue in apache?
I have an Order model and a Payment model (which FK's to Order as "payments"). I have a handler for post_delete on Payment which sends a custom signal which may do some updating on Order. The problem I'm seeing is that when I delete a Payment, the custom signal handler can still query for the deleted payment. It seems to work fine and as expected through the shell but when run via apache (mod_wsgi/python2.6/ mysql5 with innodb) my handler cannot update because the payment that should be deleted is still showing up in queries. Here is the whole thing with models,views,urls, shell test, and apache test. http://dpaste.com/hold/59869/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

That's the module for Postgres. What OS are you on? If you can tell

module.

Just slow down a little ;-) and read the django-tinymce documentation. You may also want to look at the Django forms documentation if you're new to Django.

Re: SESSION_EXPIRE_AT_BROWSER_CLOSE and normal cookie
you didn't specify max_age in response.set_cookie('myname', data),
which assumes None by default. Therefore that cookie expires when
browsers closes.

Setting up Django, Apache and Nginx on Windows Vista
I am a new user to Django and want to set it up with Apache, Nginx, and MySQL on Windows Vista for testing. I will set up on Linux once I get a shared hosting account. Does anyone know a website that explains this very well from start to finish on Vista? Or can someone explain how to do this on Windows? I have searched far and wide and all I see is how to set up on Linux. Any help would be greatly appreciated...

django apps that implement ticket filtering?
I am trying to implement a specialized ticketing system in django. At a high level, it has many similarities to the django bug tracking system, which I believe is implemented using trac. I have coded the models models and the associated django code that lets people create their tickets. Now I'm at the point where I want to implement queries. IE, let the user choose filters (and and or them together hopefully) that let you, for example, "find all tickets owned by Joe, created after 6/15/09, with status open". Nothing too new here. In looking for models of this functionality, I find the trac system to be fairly straighforward, from a user perspective. But of course, it isn't written in django. I looked at their html and javascript templates and found them very hard to wade through. I'm wondering if anyone knows of any open source django apps that do something similar? In particular, I'm interested in the html templates and associated javascript/jquery to make the filters "dynamic", as that is the area I am sort of weak in. Thanks for any pointers!

Re: Django ORM exhibiting caching like behavior in a non web based daemon script
I'm using MySQL 5.1.33
I shifted the db engine to MyISAM from INNODB and everything worked
like a charm. Then I switched it back to INNODB to test the pythonic
workarounds from
http://groups.google.com/group/django-users/browse_thread/thread/e25cec400598c06d/55fa3724d2754013?#55fa3724d2754013
'set transaction isolation level read committed' did not fix the
problem, however 'set autocommit=1' did give the daemon realtime
visibility into what the web interface was doing.
Thanks for you help and for giving me something exciting to play with
over the weekend :)

Re: Hard linking an image
Presumably you already have all of the data required to generate a chart on the server? If so, then store the chart data in a model, and just reference it by id. e.g. (or w/ a pretty URL: ) And create a Chart object and store it before sending out the HTML response. Then update your chart view so that it fetches that object and uses it as input to generate the graph. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: djangoplus widget
I found a sample contained in a rar archive with a media file included
(2 css and js) which the svn source does not have.
I changed my urls, forms and base.html to reflect that from the
example but when i reload the page it changes the default m2m field
with a text field with a plus sign next to it. If i try to add
something nothing happens.
Here's the example:
forms.py
from django import forms
from apps.spares.models import Category, Spare
from ajax_m2m_widget import AjaxMultiSelect
class MyForm(forms.Form):
spares = forms.Field(widget=AjaxMultiSelect(db_field.verbose_name,
Spare, '/spares/spare/auto/'))
categories = forms.Field(widget=AjaxMultiSelect
(db_field.verbose_name, Category, '/spares/category/auto/'))
urls.py
from django.conf.urls.defaults import *
from apps.utils.ajax_m2m_widget import auto_complete_view
from models import Spare, Category
def spare_auto_query_func(q):
return Spare.objects.filter(name__startswith=q)
def category_auto_query_func(q):
return Category.objects.filter(name__startswith=q)
urlpatterns = patterns('apps.spares.views',
(r'^spare/auto/$', auto_complete_view, {'query_func':
spare_auto_query_func, 'desc_field': 'name', 'id_field': 'id'}),
(r'^category/auto/$', auto_complete_view, {'query_func':
category_auto_query_func, 'desc_field': 'name', 'id_field': 'id'}),
last i added the fallowing to my base.html

You could add your form to your request context using a context
processor under a key other than 'form' (so it doesn't clash with
forms defined by your other views). This way, your context processor
will make this form available globally. Secondly, instead of posting
this common form to '.', post it to a dedicated view that only knows
how to process this common form.

Re: Can base.html template contain dynamic content if used by direct_to_template
OK Thanks for that. I have worked out that the context_processors
route is best for this one but the template_tags is ideal for another
part I was working on.
Thanks for the help.

What database are you using? This sounds more like a transaction isolation
problem than a caching issue.

Re: Django ORM exhibiting caching like behavior in a non web based daemon script
Which backend are you using? If you happen to be using MySQL with InnoDB,
and you haven't altered the default settings you are probably using an
isolation level of REPEATABLE-READ.
You can read more about that setting here
http://dev.mysql.com/doc/refman/5.0/en/set-transaction.html#isolevel_repeatable-read
If that is your issue there are two suggestions on how to solve the problem
here

Handling a reusable form in multiple views
Hi,
I have a simple scenario using Django 0.96 and am looking for a
cleaner solution than what I currently have:
I want to include a simple submission form (a few simple fields) on
most pages of my site. I have the form action set to '.' so that
validation can be done in place and errors displayed to the user. I am
currently checking for the POST and either handling it or creating a
new form in each of these views and then passing the form to each of
my templates, e.g.
def example_page(request):
if request.method == 'POST':
form = SubmitMeForm(request.POST)
if form.is_valid():
# do your thing
return HttpResponseRedirect('/done/')
else:
form = SubmitMeForm()
variables = RequestContext(request, {
'submitMeForm': form,
})
return render_to_response('somePage.html', variables)
I have 2 issues with this:
1 - I have to include this code in each and every view that represents
a page that has this template. There has to be a simpler way of doing
it.
2 - What if one of these pages has another Django form in it? I now
have to handle the fact that the POST could have resulted from this
form OR the other one. How would I do that?
TIA

From a brief look that tutorial is based on Django 0.96, and unless you are supporting old code written for that level you do not want to be starting out with such an old base. There are many things that changed between 0.96 and 1.0 in a backwards-incompatible way (one of which has led to your problem), you are much better off starting with 1.0.

Django contract available (200 hours estimated) £6000 GBP
We have a contract available for offer. We have been left with a project which our programmers started (about quarter way complete) for one of our clients. Our programmers have now left us so we are left with a client wanting the project finishing. It would need someone with quite a bit of Django programming experience to finish. It is a Courses booking system holding customer details and course details with resource scheduling. It MAY need to hook into Google API's like Google calendar. There is still £6000 GBP to be paid to the person who is willing to finish the project. We are based in Wolverhampton, West Midlands as is our client not that location is important. Remote working is fine. If this is of interest to anyone then please provide examples of your work and contact detail then I will get in touch with you and provide the specification document. PS I don't mind if a group of people want to work together on this project as long as they can prove how this would benefit the project without leaving room for drop-outs.

When a queryset is iterated over it stores the data so if you iterate over
the same queryset object again it doesn't do another DB query. If you want
to iterate over a new one instead of the current one you can just do
queryset.all() and then you won't be going through the cache.

Django ORM exhibiting caching like behavior in a non web based daemon script
I have a problem where I'm using Django, specifically the ORM in a non
web based daemon script to process some data from a site, by setting
the environment variables respectively so that it knows where the
settings module is, etc
I'm running the following query:-
Inqueue.objects.filter(processed = 0).order_by('-timestamp')
Now the thing is that it gets the right results the first time, but if
someone makes a change on the site that the script itself is unaware
of, it does not get new items that were added onto the site until the
script is restarted. It behaves as if it's using some caching system.
Everything works fine on an Ubuntu server, however not on windows
machines. I'm not sure why, the python and django versions are the
same on both systems.
Can anybody point me to what could be causing this behavior?
Thanks in advance

Hey Guys,
I'm new to Django and computer programming and am currently following
a tutorial from this website:
http://www.zabada.com/tutorials/django-quick-start.php
Everything worked until the activate the admin part.
My code to activate the admin in my records/urls.py is as such:
from django.conf.urls.defaults import *
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Example:
# (r'^djangotest/', include('djangotest.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/', include(divesh.records.urls)),
)
I don't exactly know what i'm doing, so please help.

Thanks for that. I was have just been playing with the
context_processors way which is great since it provides the data to
all templates.
Could you explain the include idea a bit further please.
Do you mean {% include some_other_template.html %} then how do I

This really depends on how many users have subscribed. If it's in the thousands then sending an email inline (be it via signal hooks or directly in a view or in a model.save) is going to cause some problems to the user who just submitted an article; that user will now have to wait for the entire emailing loop to complete before his/her request completes. So if you have scalability concerns like this, you might want to look at an offline-messaging-based architecture where a signal hook writes out a special message to a work queue, an offline/cron scheduled job periodically reads from the work queue and gets the heavy weight lifting done without bogging down your HTTP requests. Going back to your original question, signals are a great way to hook in event driven functionality into your apps. It allows you to keep your event processing code separate from your models, forms, or views. That's usually a good thing. Signals also allow you to add processing to a third-party django app without modifying the app's code. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Using formfield_overrides to add TinyMCE
Hi All,
I feel like there’s something simple I’m overlooking here. I can't
seem to get TinyMCE to work when I use the built-in widget from Django-
TinyMCE. This works if I uncomment the Media class at the bottom, but
the widget version of TinyMCE simply doesn't show up. Is there a
better way to tell the formfield to render with the TinyMCE widget
instead of formfield_overrides?
the admin model:
from django.db import models
from django.contrib import admin
from models import Entry
from tinymce.widgets import TinyMCE
class EntryAdmin(admin.ModelAdmin):
list_display = ('title', 'pub_date','enable_comments',
'status')
search_fields = ['title', 'body_html']
list_filter = ('pub_date', 'enable_comments', 'status')
prepopulated_fields = {"slug" : ('title',)}
fieldsets = (
(None, {'fields': (('title', 'status'), 'body_html',
('pub_date',
'enable_comments'), 'tags', 'slug')}),
)
formfield_overrides = {
models.TextField: {'widget': TinyMCE},
}
#class Media:
#js = ['js/tiny_mce/tiny_mce.js']
#js = ['js/tiny_mce/tiny_mce.js', 'js/textareas.js']
admin.site.register(Entry, EntryAdmin)
Here's the separate full model for Entry:
from django.db import models
from django.contrib.syndication.feeds import Feed
from django.contrib.sitemaps import Sitemap
#import markdown
from tagging.fields import TagField
from tagging.models import Tag
# Create your models here.
class Entry(models.Model):
title = models.CharField(max_length=200)
slug = models.SlugField(
unique_for_date='pub_date',
help_text='Automatically built from the title.'
)
body_html = models.TextField(blank=True)
#body_markdown = models.TextField() #note, if you're using
Markdown, include this field, otherwise just go with body_html
pub_date = models.DateTimeField('Date published')
tags = TagField()
enable_comments = models.BooleanField(default=True)
PUB_STATUS = (
(0, 'Draft'),
(1, 'Published'),
)
status = models.IntegerField(choices=PUB_STATUS, default=0)
class Meta:
ordering = ('-pub_date',)
get_latest_by = 'pub_date'

Yet another schema managing idea
I have been looking for a way to apply and manage my model changes to my db schema. This came out of a brainstorm yesterday afternoon. Just wanted to pass the idea through the community to see where it fits, if anywhere, upstream. The general idea is to save sqlall output from manage.py. You then maintain sql files named after your apps and their versions. Then just run the script against two of your files with the sqlall content in it. It takes the diff of two files and generates sql statements that will upgrade your schema from one version to another. I went back and captured sqlall from a couple previous releases and used them to write the code. The proof-of-concept can modify columns, create and drop tables and add contraints and indexes. All in mysql at the moment. Haven't investigated supporting other databases yet. I realize that other tools can do this too. I just wanted something small that only generated syntax. Is there anything I've missed that already does this and is more mature? Does anyone else like the idea of this style of schema management? General example of use: $ ./manage.py syncdb # initial install $ ./manage.py sqlall appname > schemas/appname-1.1.0.sql ### make modifications to model ### $ ./manage.py sqlall appname > schemas/appname-1.2.0.sql $ cd schemas $ ./gen-db-update-script.py appname-1.1.0.sql appname-1.2.0.sql > update-appname-1.1.0to1.2.0.sql $ cat update-appname-1.1.0to1.2.0.sql CREATE TABLE `appname_tableone` ( `id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `group_id` integer NOT NULL, `content_type_id` integer NOT NULL, `object_id` integer UNSIGNED NOT NULL, ) ; ALTER TABLE `appname_tabletwo` ADD COLUMN `prune_count` integer NOT NUL; ALTER TABLE `appname_tabletwo` ADD COLUMN `prune_age` integer NOT NULL; ALTER TABLE `appname_tabletwo` ADD COLUMN `prune_inactive` integer NOT NULL; ALTER TABLE `appname_tablethree` MODIFY COLUMN `arch_id` integer NOT NULL; $ mysql -u someuser -p databasename < update-appname-1.1.0to1.2.0.sql Radez --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Need help
I had this same problem...the user and pass were fine but no users could authenticate on any DB, regardless of settings. Turns out my issue was only that I needed to add the string "localhost" to the host parameter. It's odd since the comments specifically state to leave it blank for localhost...but oh well. It worked. DATABASE_HOST = 'localhost' # Set to empty string for localhost. Not used with sqlite3. Odd.

Can base.html template contain dynamic content if used by direct_to_template
I want to build a site which has latest news on the side of all the pages, I wanted to build the pages using simple templates (static content) and then reference them using the direct_to_template in the urls file. Since each template extends base how can I get base to contain the latest news or do I have to write a view for each template and pass the news into them?

Re: MemoryError on bigs list of items
To clarify, you're displaying a list of 1000+ models on a single page, yes? My understanding is that the debug_toolbar analyzes each SQL query and keeps each result in memory before rendering everything in the template. I don't know how your query works, but let's take an extreme case and say your request executes 1000+ queries. In addition to keeping 1000 models in memory, the debug_toolbar now has to also contain the query data for 1000 queries. If you have a small amount of memory, this could eat it up pretty quick. I don't think setting MaxRequestsPerChild = 1 would do anything to cause a MemoryError. It should actually help, since if you're restarting the process after just 1 request, any memory leaks won't have time to build up. -- Andrew On Jun 25, 1:15 pm, Frédéric Hébert wrote: > Hi there, > > I'm facing with a curious problem. > > I've an project which is hosted on three differents servers : > > one (my local PC) : > debian lenny / > python 2.5.2 / django 1.0.2 final > apache 2.2.9 / mod_python 3.3.1-7 > > the two others (production and validation server) : > OpenSUSE 11.1 / > python 2.6.2 / django 1.0.2 final > apache 2.2.10 / mod_python 3.3.x-x > > Two months ago, I've launched this project both on production server > and validation server. > Neither validation server nor production server caused me any > trouble. > > Today, to test something, I've installed debug_toolbar extension and > set MaxRequestPerChild to 1 in Apache's conf file, both on my local > dev PC and on the validation server. > > When I want to display two long list (1000+ items each) i get a > MemoryError one time out of two.

The best thing to do here is to use an 'inclusion tag', which as the
documentation says is a template tag that renders another template. So
you'd define a small template with just the html for rendering your
news list, then pass that as the argument to the decorator when
defining the tag. The function then returns a dictionary context, as
you would use in a view.
The second thing you can do with the inclusion tag - to answer your
other question - is to use the decorator with takes_context=True. Then
it will take a single parameter, context, which is the parent
template's context, so you don't need to pass in your object
explicitly.
@register.inclusion_tag('newslist.html', takes_context=True)
def news_for_this_page(context):
...
return {'newslist': newslist}
See the documentation:
http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#inclusion-tags

Inclusion tags might help you out with the template idea, but generally for
variables like this I like to put them in context like this:
http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#setting-a-variable-in-the-context
Those docs should help you out a lot. Also the default tags are pretty good
examples to look at:
http://code.djangoproject.com/browser/django/trunk/django/template/defaulttags.py
Hope that helps,
Michael

Re: Django and PyAMF - RemotingError
IIRC, pyAMF tries to turn all python objects into amf related ones upon
output. What you may be seeing here is that querysets aren't able to make it
through this conversion. Check your apache error logs for the stacktrace, if
you have one, or like Randy said, set Debug = True.

Rendered output from a template tag
I created a simple_tag:
def news_for_this_page(page):
if page.entity_set.all(): # check page belongs to an entity first
e = page.entity_set.all()[0] # first entity will be only one
newslist = []
for item in e.newsitem_set.all(): # get entity's news items
newslist.append(item.headline) # add them to the list
return newslist
else:
return "No news is good news"
What this spits back into the page is:
[u'Man bites dog', u'Dog bites man', u'Nixon resigns']
so obviously I need to process that list, making it a and putting
in the links before sending that to the template.
To do this, I think I need my function to call another template to
render it appropriately - is that correct?
Are there any shortcuts in this process?
For example, to use my template tag I use {% news_for_this_page entity
%}. It would be neater to use something like {% news_for_this_page %},
since entity will always be set.
Thanks,
Daniele

Why is (db) Field.form_class hardcoded to TypedChoiceField if field has choices?
Hi all,
I am trying to implement a "FlagField" that can be used to store
binary flags in a single integer value in the DB. The approach that
looks most promising is subclassing Integer Field, pass in some
choices as possible flags (which will be internally converted into the
appropriate bitmasks) and use subclasses of MultipleChoiceField and
CheckboxSelectMultiple as form field and widget, respectively.
This all works nicely besides the fact that the formfield() method of
Field forces the Field to use TypedChoiceField as the form_class if
choices are present (django/db/models/fields/__init__.py:326). So
there is no way for me to use my own form_class unless I override this
whole (otherwise perfectly suitable) method. The workaround I have
taken is to use a different name instead of 'choices', but I would
prefer to stick with this name as it is intuitive in the django
context. (One could argue that choices should be reserved for cases
where a single item should be chosen form choices, but I doubt this
would be a worthwile distinction and there is nothing in the code/docs
that suggest this).
My proposal would be to change the formfields() method to check, if
choices are defined, if form_class is a subclass of ChoiceField an if
so, leave it alone. Otherwise the default (TypedChoiceField) can be
used as it is the case now. What do you people think?
I could open a ticket if feedback here suggests so. All other
suggenstions regarding my code are welcome!
All the best,
flo ledermann
Here is my (working) code:
--
# fields.py
from django.db.models import IntegerField
from django.forms import BooleanField
import forms
class FlagField(IntegerField):
def __init__(self, flags, **kwargs):
# i would like to use 'choices' instead of flags, but this is
impossible
assert flags, "%ss must have flags argument set." %
self.__class__.__name__
self.flags = flags
super(FlagField, self).__init__(**kwargs)
def formfield(self, **kwargs):
defaults = {'form_class': forms.FlagField,
'choices': self.flags }
defaults.update(kwargs)
# this has to be done because admin assigns a widget to
IntegerFields,
# which we do not want here
defaults.pop('widget', None)
return super(FlagField, self).formfield(**defaults)
--
# forms.py
from django.forms import MultipleChoiceField, CheckboxSelectMultiple,
SelectMultiple
from django.utils.encoding import force_unicode
class FlagWidget(CheckboxSelectMultiple):
def render(self, name, value, attrs=None, choices=()):
flags = []
for i, flag in enumerate(self.choices):
if value & 1< 0: flags.append(flag[0])
return super(FlagWidget, self).render(name, flags, attrs,
choices)
def value_from_datadict(self, data, files, name):
raw = super(FlagWidget, self).value_from_datadict(data, files,

MemoryError on bigs list of items
Hi there, I'm facing with a curious problem. I've an project which is hosted on three differents servers : one (my local PC) : debian lenny / python 2.5.2 / django 1.0.2 final apache 2.2.9 / mod_python 3.3.1-7 the two others (production and validation server) : OpenSUSE 11.1 / python 2.6.2 / django 1.0.2 final apache 2.2.10 / mod_python 3.3.x-x Two months ago, I've launched this project both on production server and validation server. Neither validation server nor production server caused me any trouble. Today, to test something, I've installed debug_toolbar extension and set MaxRequestPerChild to 1 in Apache's conf file, both on my local dev PC and on the validation server. When I want to display two long list (1000+ items each) i get a MemoryError one time out of two. The remainder of project goes fine. I've resetted MaxRequestPerChild to 1 (default value on OpenSUSE) and commented out debug_toolbar's things in my settings, restart Apache. But error happened again on the validation server. On my local PC, it works well, with debug_toolbar and MaxReq.. set or not. I've pasted the traceback here http://dpaste.com/hold/59667/ AFAICS, an exception occurs when django tries to render a debug template Here is an exerpt of my vhost conf file on OpenSUSE : DocumentRoot /srv/www/enseignements-dev.ehess.fr/ue SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE ue.settings_dev PythonDebug On PythonPath "['/srv/www/enseignements-dev.ehess.fr/', '/srv/www/ enseignements-dev.ehess.fr/ue/'] + sys.path" Many thanks in advance, Frédéric --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Where to put form definitions?
My reading of the documentation isn't clear on where form definitions could or should be defined. Is it better to define forms inside an apps views.py file, or should I put the form definitions into a separate forms.py file and import it into the views as necessary? The latter seems more reusable. Does anyone have reasons to do otherwise? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: TinyMCE django admin
Hey Joost, I was just googling and came across all those old hacky ways to integrate tinymce which I finally did yesterday. Its working. But yes if its something builtin now I should go for that. However I dont know If I can easily change the properties that way for the editor. Right now in the Hacky way I change plugins,themes,skins stuff and it shows up the changes. Can we do this with widgets?

I can definitely understand how someone new to the framework, trying to use a custom widget to do HiddenFields (which is more arcane that it should be IMO, but that's off topic) and reading the BooleanField docs could get confused about using them _without a checkbox widget_. I'm going to open a ticket against the doc here and submit a first pass at a documentation patch.

Re: Trouble with extra statement in Django 0.96
I have since discovered that I can use the following:
585 if len(name) > 0:
586 members = MemberRole.objects.filter(
Q(member__first_name = 'John') |
Q(member__last_name = 'John'),
587 start_date__lte = today,
588 end_date__gte = today,
589 )
Except I am still curious about the .extra() issue I was having before
as it will allow me to use regular expressions (which were not
introduced as __regex until 1.0)

Re: passing template variable to templatetags
you must use the django.template.resolve_variable method:
obj = Foo.objects.get(id=resolve_variable(self.id, context))
which would be called within the render method of you templatetag
class, which contains the "context" from the view.

You may want to eavesdrop on the Django Developers group (as opposed to this Django Users group) where Alex Gaynor has been posting updates on his GSoC project to add multi-DB support to Django[1].

Isolating Django Models
Hey everyone,
I was wondering the best way to isolate django models so they can be used
in other python applications. I have seen the django extensions, which are
very helpful. But a 'job' is still coupled to the django environment.
Ideally I'd like to do this:
* Write some function foo() that uses mysite.myapp.models
* Be able to import that function into a pure python script. So I could run
'python myscript.py' and it could run foo() without any errors.
I have done the following hack, which lets me import the models, but I get a
strange error when I try to access the database:
# this is in /project/app/scripts/
import sys, os
os.environ['DJANGO_SETTINGS_MODULE'] = 'datamanager.settings'
sys.path.append('../../../') # Add top level project path (for settings)
sys.path.append('../../') # Add app level to path
from myapp.models import mymodel
# At this point I am good to go, until I try to access the database.
>>> mymodel.objects
>>> mymodel.objects.all()
Traceback (most recent call last):
File "", line 1, in

Are your working with sessionss? That is, are your working with the session object and saving there some information? On the afirmative case check the object you're using, perhaps is a lazy object or a non serializable one. You can check also where are saving your sesion data.

Sessions Not working.
Production Box spec: mandrake 10.1.1, python2.3, libmysql15-5.0.1, MySQL1.0, Django 1.0. can't get sessions to work. My site (and sessions) works on my development box with a more or less current version of ubuntu, when I copy over the project to the production box it does not work. I have run "python manage.py syncdb" and the database is created correctly, I have made sure the settings.py is correct, but Djangos debug page states there is "No Cookie Data" when I navigate to the site. I also tried installing latter versions of python, Django, MySQLdb, mod_python and apache but same problem. It seems to be a problem with Django or Python because the problem persists even when I run "python manage.py runserver" and axis my site from there. This means users can't login which renders the site useless. I can't change production box unfortunately.

It's just a normal ManyToMany relationship between user and group. So
you can do:
{% for group in groups %}
{{ group.name }} - {{ group.user_set.all }}

Will future Django releases support multiple databases?
Right now, Django doesn't seem to support the multiple databases on the same server or different servers. Will that feature be available out of the box for future releases? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Perhaps your emoticon at the end was intended to convey a light comical tone but tone is extremely hard to convey in email and telling someone to go away because they've expressed some frustration strikes me as rude. Everyone is free to simply not respond to anyone they feel is expressing unreasonable frustration; I don't see that it helps matters much to try to tell them they are being unreasonable. To the original poster, if you read the documentation on django.forms.BooleanField: http://docs.djangoproject.com/en/dev/ref/forms/fields/#booleanfield you'll see it doesn't say anything about the validation behavior being dependent on the widget in use. So it doesn't matter what widget you use, if you want to be able to validate False as a valid value, then you need to include required=False in the form field definition. (There was a huge long contentious discussion about required=True implying a BooleanField value must be True in order for the field to pass validation -- you could find in the ticket tracker if you looked for it. Not everyone agrees with the choice made, but it was clearly an issue where not everyone was going to agree no matter what decision was made. It's been made and won't be changed and the way to make your case work is simply pass required=False on the form field definition.)

HTML renders > correctly, but actually, you can not use like that?! http://docs.djangoproject.com/en/dev/ref/forms/fields/#booleanfield You should have read that section, esp: "Validates that the check box is checked (i.e. the value is True) if the field has required=True." and the note following: "Since all Field subclasses have required=True by default, the validation condition here is important. If you want to include a checkbox in your form that can be either checked or unchecked, you must remember to pass in required=False when creating the BooleanField" By saying you have a very bad experience with Django because you didn't read the documentation there's not much we can do for you. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Writing a reusable app
Hi all: I am refactoring a django app to make it reusable and share it open sourced to the world. There is a lot code which I think it is optional and maybe not everybody will want to use, like some model fields, url patterns of view functions. so my initial approach is to release only the minimal version and let them add whatever they need. But then a question arises, regarding maintenance and update of the application in the projects where the app is gonna live. When I will release further versions with bufixes or new features, then should these people download the app, and maybe do a merge with their modified versions? That would be against the philosophy of a django app for me, that is, to be de-coupled from other parts of the project. Also conflicts may appear, if my next app versions differ a lot from previous ones. The opposite approach I have seen in other apps is to include everything the developer considers suitable. But doing this means forcing people to include useless stuff for their projects, like model fields they won't never use in their database schema, for example. So how do u guys think I should target it? Minimalistic or full- batteries included?

Get Users' Groups
Hi! I searched on documentation but I didn't see anything related with managing users' groups, I want to do something like a "staff page" and for that I need to get a list of groups, I need to get the NAME of each group and I need to get the list of members of each group. How can I do this? I am using the User and Group django Models. Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Very bad experience in Django...
BooleanField limits only to CheckBox? But I set widget=HiddenField It does not report error. HTML renders correctly, but actually, you can not use like that?!

Hard linking an image
Hi, I have a chart which I generate on the fly. Basically, I have hard linked an image. The image src contains GET parameters, which is used to generate the chart image via matplotlib. The resultant image is returned back as 'Content-Type' = 'image/png', and thus the chart is displayed. i.e. is there in HTML - created using templates. The parameters key1, key2, field1, field2 etc are used to create the image. Now, this was working perfectly till now. Now, I need to create a huge chart with lot of keys and fields. But, when I tried the same mechanism, it failed because it is above the maximum characters supported by GET. Even though I could not find any specific spec which mentioned the max char limit, I understand that many browsers support very less characters only ~300. In such a case, how can I create the chart on the fly? Is there a way to send the data as POST while hardlinking? Since I am getting the values and generating the links using templates, I cannot think of too many options. What si the usual mechanism used by fellow Djangoites? Any help would be much appreciated.

Re: How to use MEDIA_URL on flatpages content?
I think I got your concept, converting all MEDIA_URL to corresponding
url before displaying.
But I still curious to know where should I put this code in the
project?
I've been thinking and can only come up with a way, by creating a new
middleware replicating FlatpageFallbackMiddleware
but instead of calling a view in django.contrib, it will call my new
view that has been modified by your suggestion.
However, I don't like this method. It forces me to copy an entire
django's view, which i think it's not a future-proof.
Your suggestion?
