At the moment this is work in progress. There is some development going
on to finish up model-aware validation and complete some earlier work on
model validation. At that time, you'll be able to call
my_model.validate() and have things work similarly to how they do with
newforms.

Right now, there's a validate() method on the Model class, but it is
incomplete and not recommended for production use.

In the interim, doing things in the save() method is possible, although
it's not a brilliantly nice design, since save() should never raise
validation errors and, if it does, you won't get feedback to, say, the
admin interface or places like that. But it's the workaround you need to
do at the moment.

Thanks. Maybe I will have a go at it. Seems like it would be fairly
straightforward, even for someone of my limited abilities. I'm already
fairly familiar with us_states.py, as I made a dirty hack to include
Canada in it.

If you're asking for a function that converts 'KS' to 'Kan.', then, no,
there isn't anything like that at the moment.

For better or worse, localflavor is becoming a catch-all for that kind
of stuff, so write up a patch if you think it's genuinely useful. I
don't personally have strong opinions either way, since there are more
important states to me than the US ones and I don't find AP style to be
particularly convincing in a lot of cases, but I realise some people
like to use it, so it might well be worth including.

AP-style state names

I just know this has got to be lurking around in Django somewhere...
If I use USStateField, is there a filter or other method to output the
state name in Associated Press style? I know there's AP filters for
times and numbers, but can't find anything for states. and looking
around in localflavor I don't see any mapping that would connect, say,
Kan. to KS.

Anyone got any ideas?

Well, you can't set up a query for something that isn't in the database.
But the values are right there in THE_MATERIAL.  If you want a list of just
the text values, stripping away the numeric choices, some simple Python:

material_list = [y for x,y in THE_MATERIAL]

would do it.

What percentage of requests are actually yielding static pages?

People often too quickly run to lighttpd thinking it will somehow
magically solve all their problems, but if the bulk of the requests
are actually dynamic and served by Django, and it is Django and the
database which are the bottleneck, it will make very little if any
difference.

Now to try and get to what the real issue may be, expand on what you
mean by 'server stuck when I had too much hits'. What exactly is
getting stuck, the connections through to the database, or Apache
itself running out of processes and/or worker threads to keep up with
the volume of requests? Or is the box starting to run out of physical
memory and starting to swap excessively.

Where the problem lies will guide what you may need to do.

How to select all the values from my Field attribute 'choices?

[Greg]

Hello,
When I first developed my application I created a table that stored
all the different types of materials

class Material(models.Model):
material = models.CharField(maxlength=100)

To get all the materials in the table all I needed to do was query the
table.  Recently, I've been going through my code to see if I can
clean it up.  So I deleted my table Material and made it into a
'choices' attribute.  So now I have

class Collection(models.Model):

THE_MATERIAL = (
('1', 'Paper'),('2', 'Plastic'),('3', 'Other'),
)

material = models.CharField(max_length=50, choices=THE_MATERIAL)

///

However, now I want to be able to do a query that returns all of the
values in THE_MATERIAL (even if it's not being used by any
collection).  How would the query be setup to do this?

Thanks

Scaling the server

[Michel Thadeu Sabchuk]

Hi guys,

A few weeks ago I had problems with my dedicated server, it was
stucking twice or more times a week. After some digging, I solve the
problem updating the mysqldb lib version. The server goes ok almost
all the time, but I still have server stuck when I had too much hits.

My server had 1.8mi to 2.2mi of hits a day, I found that I must scale
my server. Before start the machine acquisition and money expending, I
wanted to get some experience from you. I don´t want to kill a fly
with a cannon ball ;)

I had django running over a mod_python/apache instance that are
serving my media files too. One of my bottlenecks was the home page,
yesterday I start to generate it through a script called by cron. I
follow this approach even using locmen cache backend. Is it a good
idea to use lighttpd on the same server to serve static files or
should I need to setup a different server to database and maybe
another to media files?

Thanks for any help,
Best regards.

Re: Error message when viewing admin? (ViewDoesNotExist at /admin/)

[DJango Fett]

The same thing happens to me.  I was going through the Tutorial to
make the Poll application.  The admin url was working fine.  When I
added in the patterns for the poll app, I get the same error you did.
If I comment out the admin line, the poll lines work fine.  If I
comment out the poll lines, the admin line works fine.  Where yours
says 'startsess', mine says 'vote'.  I imagine it is because it is the
last line for all of the polls patterns:

from django.conf.urls.defaults import *

urlpatterns = patterns('',
  (r'^admin/', include('django.contrib.admin.urls')),
  (r'^polls/$', 'index'),
  (r'^polls/(?P\d+)/$', 'mysite.polls.views.detail'),
  (r'^polls/(?P\d+)/results/$',
'mysite.polls.views.results'),
  (r'^polls/(?P\d+)/vote/$', 'mysite.polls.views.vote'),
)

Re: Need help selecting a Django hosting provider

We are very happy with webfaction (http://www.webfaction.com). Setting
up a django instance, database, etc. is a breeze. It also seems that
it would be pretty easy to scale with them (though we have not tried
this yet), at least up to medium+ traffic levels.

Re: which Django version to use for live site to be released in end of february 2008

[Jeremy Dunck]

We're running on r6023 OK.  It was a quiet point on trunk after
Unicode landed and the related bugfixes were done.   If I were picking
now, I'd find a rev closer to current trunk.  But I'm pretty
knowledgeable about Django and don't mind managing my own rev and
applying important bugfixes when needed.

0.96 is r4810; trunk is now r6600.If you want lots of support and
stable, accurate docs, you probably want 0.96.   If you're concerned
about large changes later, something later might be worth going with,
but it will be a bit of a moving target.

As a small tip, I watch trunk and if there's something really useful
that's easy to pull in, I do that.  I was using {% with %} on 0.96 +
patches for a long while.

Have a look at this:
http://code.djangoproject.com/wiki/BackwardsIncompatibleChanges
if you need more details.

As this particular method of advertising has proven to be a great way
of generating revenue I thought I'd give this new widget from
WidgetBucks a try. It takes products from top shopping websites like
Amazon, ebay and Walmart and displays the best prices using an
animated banner that you can display on your website or blog using
their widget code. They even have their own algorithm engine called
MerchSense for displaying products that are relevant to your websites
content, it even adapts to new content that you write so it's great
for blogs.

The widget also only displays the highest paying products. They say
that publishers that have tested the widget are seeing a $3-6 CPM
which compared to Google's Adsense is pretty good! Only difference
being is that the widget will not fit seamlessly into your content
like Adsense. For a CPM that high it's worth a try though!

Higher eCPM
Some early adapters are claiming earnings of $3 to $6 CPM (cost
per thousand impressions). Most ad networks are paying out $1 to $2
CPM. Of course only time will tell if the $3 to $6 CPM carries over
for everyone, but it’s worth a shot to see what happens.
$25.00 signup bonus
You need $50.00 for a payout and the $25.00 bonus puts you halfway
there. The only “condition” is that the bonus only hits your account
after you have made another $25.00 in clicks. Not a big deal.
Referrals
For every new referral you send to the Widget Bucks network you
earn $5.00 ONCE THEY HAVE EARNED THEIR FIRST $50.00 payout.
http://www.widgetbucks.com/home.page?referrer=549002

Update - The above is incorrect. That is what the website said
when I wrote this article. Currently it states: With WidgetBucks’
Referral program, affiliates can earn a 10 percent referral fee based
on the commissions earned by the people they refer. Affiliates receive
this 10 percent for the full 12 months after the new member joins.
Payouts to affiliates are monthly, along with their commission checks.

What makes Widget Bucks different than all the rest?
First and foremost it’s a widget that goes in the sidebar so it
obviously has application for blogging. Oh and if you don’t like a
traditional widget you have an assortment to choose from. I went with
a traditional 468×60 banner. Also you can either choose the
catergories it displays, or you can let MerchSense handle it for you
automatically.

MerchSense™ is Mpire’s patent-pending contextual algorithm
engine. It detects and analyzes the content of your website or blog to
determine what product offers are most relevant to your audience. If
you choose the MerchSense option when creating a new widget, simply
place the code on your site and let MerchSense automatically provide
the most appropriate ad content. MerchSense evaluates your editorial
information daily, so, as your content changes, WidgetBucks will
dynamically offer the highest-yielding products.

or read more http://r.yuwie.com/chiangmai

Beyond those things the reported CPM of $3 to $6 is neary twice
the industry average. Not bad at all.
What other features and benefits are there?
Taken directly from the Widget Bucks “about us” page.

* Self-service, scalable and relevant content that’s free and
easy to publish
* Dynamic, contextual widgets act as content (vs. ads) that
more effectively targets your users, not the masses
* Dynamic Ad Yield Management matches the best merchant for
each product while offering consumers the best price
* MerchSense (patent pending) contextual algorithm
automatically targets the right products for your site
* Proprietary analytics, pricing and relevancy engines display
buying trends of 100 million shoppers
* Extensive reporting tools and daily updates; Payouts are
monthly
* Complements existing programs, such as Google AdSense
* Over 300 configurations, 256 color schemes and formatted for
major IAB standard sizes
* Manual configuration also available by category
* Product listings from 30,000 merchants including trusted
leading brands

What are YOU waiting for?
I know you’re interested so why not just sign up for Widget Bucks
and give it a shot? For $3 to $6 CPM, and an instant $25.00 signup
bonus what have you got to lose?

Do you need unicode (i18n or non-ASCII charsets)?  That's the biggest
single determining factor.

which Django version to use for live site to be released in end of february 2008

[ydjango]

I am working on product which will be released end of february. I am
planning to use Django for building the site. I am new to Django

Which version should I use - SVN or 0.96?

If I use 0.96, I am worried migration to 1.0 will be very painful and
time consuming.
If I use SVN version , I am not sure how stable it is?
Are there any production sites using the svn version.
Can some one please recommend?

Re: newforms: required field mark

[panta]

I've done something similar for auto-generated forms (form_for_model()
and form_for_instance()), by derivating a class from BaseForm and
providing my own _html_output() method, which emits the label with
different attributes depending on its "requiredness" (using the
'attrs' parameter to BoundField.label_tag()).
Then pass your derived class to form_for_model() and
form_for_instance() using the form named parameter.

The code:

class ExtForm(forms.BaseForm):
def _html_output(self, normal_row, error_row, row_ender,
help_text_html, errors_on_separate_row):
"Helper function for outputting HTML. Used by as_table(),
as_ul(), as_p()."
from django.newforms.forms import BoundField
from django.newforms.fields import Field
from django.newforms.util import flatatt, ErrorDict,
ErrorList, ValidationError
from django.utils.html import escape
from django.utils.encoding import StrAndUnicode,
smart_unicode, force_unicode
top_errors = self.non_field_errors() # Errors that should be
displayed above all fields.
output, hidden_fields = [], []
for name, field in self.fields.items():
bf = BoundField(self, field, name)
bf_errors = self.error_class([escape(error) for error in
bf.errors]) # Escape and cache in local variable.
if bf.is_hidden:
if bf_errors:
top_errors.extend(['(Hidden field %s) %s' % (name,
force_unicode(e)) for e in bf_errors])
hidden_fields.append(unicode(bf))
else:
if errors_on_separate_row and bf_errors:
output.append(error_row %
force_unicode(bf_errors))
if bf.label:
label = escape(force_unicode(bf.label))
# Only add the suffix if the label does not end in
punctuation.
if self.label_suffix:
if label[-1] not in ':?.!':
label += self.label_suffix
if field.required:
label = bf.label_tag(label, attrs={'class':
'required'}) or ''
else:
label = bf.label_tag(label, attrs={'class':
'optional'}) or ''
else:
label = ''
if field.help_text:
help_text = help_text_html %
force_unicode(field.help_text)
else:
help_text = u''
output.append(normal_row % {'errors':
force_unicode(bf_errors), 'label': force_unicode(label), 'field':
unicode(bf), 'help_text': help_text})
if top_errors:
output.insert(0, error_row % top_errors)
if hidden_fields: # Insert any hidden fields in the last row.
str_hidden = u''.join(hidden_fields)
if output:
last_row = output[-1]
# Chop off the trailing row_ender (e.g. '')
and insert the hidden fields.
output[-1] = last_row[:-len(row_ender)] + str_hidden +
row_ender
else: # If there aren't any rows in the output, just
append the hidden fields.
output.append(str_hidden)
return u'\n'.join(output)

Hope this helps.
Cheers,
Marco

Re: Does anyone know where I can find cache tag library?

[Karen Tracey]

If you're referring to template fragment caching, it's been in trunk since
rev. 6580 (just a couple of days). Doc is here:

http://www.djangoproject.com/documentation/cache/#template-fragment-caching

Does your checkout not have django/templatetags/cache.py?  It's certainly in
svn:

http://code.djangoproject.com/browser/django/trunk/django/templatetags/cache.py

Re: Authenticating static content when not using mod_python

[AndyB]

(my reply via email doesn't appear to have made it to the list - sorry
if the first paragraph is a repeat for anyone)

Thanks Chris, I didn't know about this and it would be the ideal
solution if I could get Dreamhost to install mod_xsendfile! Still
hopefully this will be useful for someone out there who is stuck with
FCGI but has some control over what modules are installed.

Now back to having to do it the laborious way - I remember being told
that django.views.static.serve wasn't meant to be used in a production
environment but in this context it seems to do everything I need (MIME
types etc.). Bearing in mind Django is going to have to handle the
static content for me is there anything wrong with using
django.views.static.serve?

Re: can contrib.sites.models (Site) belong to an application model?

[Tim Perrett]

For sure, ive been playing with it and have seen that I can have one-
to-many (Site has-many Partners) and ManyToMany, but I was looking to
have it so that one partner has many sites? Is the ManyToMany the only
way to do this? As in terms of a DB schema, its not a many to many
relationship.

Ideally I would like to be able to determine what partner that site
belonged to, is that even possible? It just seemed to me that there
might well not be a way of doing it???

Thanks for any help in advance

Tim

Sure - Site is just a model in the contrib 'sites' application, so you
can import and reference the Site model just like you would for any
other Many-to-many relation:

from django.db import models
from django.contrib.sites.models import Site

class Partner(models.Model):
... your attributes here
sites = models.ManyToManyField(Site)

GET parameter in a template

[Rufman]

hey

I render my template by passing a RequestContext object. This way i
can access the user info ({{ user.username }}). I tried displaying the
GET parameter like this: {{ get. }} and
{{ request.get. }}. Either way i don't get any
output. Is there even a way to display the get parameter without
explicitly passing it in the context?

thanks for the help
