Using property fields in Models:'_QuerySet' object has no attribute 'new_summary' error

[ydjango]

I defined two property fields in my model as below

but TableName.objects.all() or filter() is not retrieving them.
It is retrieving only the regular model fields.

   Any clues on what I am doing wrong?
Ashish

   def _get_new_summary(self):
"Returns the news summary."
return '%s - %s' %(task_summary,"Ashish")
new_summary = property(_get_new_summary)

def _get_severity_desc(self):
"Returns the Severity Description."
p =Severity.object.get(pk=self.severity)
return p.display_desc

severity_desc = property(_get_severity_desc)

Re: alternative to (r'^house/edit/(\d+)/$',ediHouse)?

[ydjango]

Thanks, I will use Slug, which will be unique and alphanumeric but
will not be sequential.

I agree best protection is proper authorization, and that I check on
each page/request if the user is authorized to view this data or not.

I just hate the idea of some user just incrementing ids in url and
trying to view the data, he is not supposed to. (eg. putting boss's
employee id in url to see his salary)

I am restricting the data viewed through use of restrictive parameters
in queries  which can be defeated by changing the ids in url, if I use
primary ids.

thanks
Ashish

Re: ModelMultipleChoiceField updating HTML choices after 2nd reload

[Rishabh Manocha]

Justin,

Thanks - that does exactly what I was looking for. Initially, I too
had to refresh the page once before I saw a list of options, but using
fields instead of base_fields fixed that.

This may be a stupid question, but is there a recommended/established
way of reading the django code. I am still fairly new to python, so I
don't quiet understand the nitty gritty's yet :(.

Best,

R

Re: Images and Stylesheets

[Doug Van Horn]

Here's my rewording of your question:

"How do I serve static content?"

Websites need to serve up your HTML, CSS, JavaScript, and images.

In Django, your views are serving up your HTML.  What you need to do
is serve up the rest of that stuff.

The first way to serve static content, when you are using the Django
development server, is to use the 'django.views.static.serve' view.
You'll find it documented here:

http://www.djangoproject.com/documentation/static_files/

Here's the gist, as you might include it in your urls.py:

from django.conf import settings
(r'^static/(?P.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT}),

Then, in your HTML files, you might include CSS and image files via
the following:


and


A more 'correct' way might look like this:



Note that MEDIA_URL gets included as a template variable when you use
the 'django.core.context_processors.media' template context processor
and pass a RequestContext to your template rather than a regular
Context.

When you get around to deploying into an Apache environment, you'll
need to either run a second 'media' server (think 'media.example.com'
virtual host) or you can turn off python handling for certain
locations under your app host and serve up the static files.  Consult
your Apache docs for more info (specifically, the Location, Directory,
and Alias directives).  If you're deploying against lighttpd I would
guess the concepts are similar.

I guess you don't actually /need/ to serve up your static content via
Apache, the above urls.py entry will work fine under Apache.  It's
more a matter of you /should/ (see the static_files link, they give a
better explanation...).

Hope this helps.

Re: alternative to (r'^house/edit/(\d+)/$',ediHouse)?

[Ned Batchelder]

Strictly speaking, exposing the primary key is not a security issue.  
Primary keys are not a secret, just an id.  You need to secure your data 
based on authenticated credentials and some sort of authorization system 
that controls who can do what with each piece of data.

Some people don't like using sequential primary keys because they are 
exposing information about their system.  For example, with your system, 
I can tell how many houses you have in your database by probing URLs.  I 
guess you might consider that a security concern.  If so, use a 
randomized slug as others have suggested.

They are indeed

> that means

To "serve" simply means that the web-server (usually Apache or 
lighttpd) listens for requests for files and responds by 
"serving" them.  An example might be

   C:  GET /blog/2008/3/14/my-pi-day-post HTTP/1.1
   C:  Host: www.example.com
   S:  HTTP/1.1 200 OK
   S:  Date: Mon, 23 May 2005 22:38:34 GMT
   S:  Server: Apache/1.3.3.7 (Unix)  (Red-Hat/Linux)
   S:  Last-Modified: Wed, 08 Jan 2003 23:11:55 GMT
   S:  Etag: "3f80f-1b6-3e1cb03b"
   S:  Accept-Ranges: bytes
   S:  Content-Length: 438
   S:  Connection: close
   S:  Content-Type: text/html; charset=UTF-8
   S:
   S:  My first blog page

(C = client/webbrowser, S = server).

It may be helpful to learn some rudimentary HTTP (the protocol 
over which all of this is being served).

   http://en.wikipedia.org/wiki/HTTP

Or at least install the "Live HTTP Headers" FireFox extension 
that allows you to watch/record the HTTP transactions.  But the 
basic gist is that your browser requests a page; the server 
"serves" this page (dynamically, created by via Django).  Your 
browser then sees references to other external files (images, 
CSS, JavaScript, etc) and makes requests for each of these.  The 
server receives each request and returns ("serves") the requested 
content--an image, a CSS file, a JavaScript file, or even 
additional dynamic content from another Django source.

> 
> The other problem is getting css to work with my site.

Both images and CSS files (as well as JavaScript source files, 
when you get there) are considered "static media".

Django's development server can serve these static media files. 
I like to use the following in my urls.py file:

if 'runserver' in argv:
urlpatterns += patterns('',
(r'^media/(?P.*)$',
'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT}
),
)

This allows me to serve media from the development server (which 
get put in the directory specified by MEDIA_ROOT), but it
doesn't alter my urlpatterns in production where the actual
web-server handles serving media.  To move to production, you'll 
want to configure your server (likely Apache or lighttpd) to 
serve these static files.  The server is very good at serving 
static (non-dynamic content), so it's best to let it handle these 
files.  Django *can* handle them, but it's not designed to do as 
much (it's designed to serve dynamic content).  There's a good 
writeup at

http://www.djangoproject.com/documentation/static_files/

regarding how to configure your web-server (Apache or lighttpd) 
for serving these static files outside of Django.

Hopefully this gives you some hints, pointers in the right 
direction, terminology to search the web, and tips in general to 
get things working.  As always, the list is a pretty friendly 
place, and will try and help guide you.

Re: alternative to (r'^house/edit/(\d+)/$',ediHouse)?

[Doug Van Horn]

FWIW, I don't see a security issue with exposing a surrogate primary
key to the public...

If you're hung up on the issue, though, take Tom's advice and use a
slug for each house as an unique key.  You might find the street
address of a house to be a good slug candidate...

Announcing the Django Dash!

[Daniel Lindsley]

We'd like to announce the first Django Dash
(http://www.djangodash.com/) to the community. Django Dash is a web
application building competition for Django developers. The gist is
that you and (optionally) one other person can form a team and have 48
hours to crank out a full Django application. Your application will
then be pitted against others for bragging rights (and hopefully some
prizes).


==

What Is Django Dash?
A 48 hour, start-to-finish race to produce the best Django-based web
application you can. Mostly for fun/bragging rights but we're working
on upping the ante.

Who Can Compete?
Anyone but myself and (hopefully) three other judges, though this is
subject to change depending on popularity.

When Is It?
We'll be hosting the Dash on May 31 - June 1, 2008.

Where?
We're running this over the web, so you can be anywhere you like.
Coffee shop, work (though we're not responsible for the ramifications
of that one), at home, wherever you can find internet access and
power.

How Can I Compete?
First, please peruse the rules and judging information at
http://www.djangodash.com/. We will be opening registration for teams
on May 3, 2008. You're not allowed to start anything but ideas and
paper mockups until the competition begins on May 31, 2008.

Why?
It's a chance to test yourself and push your limits. A chance to show
people what you're capable of. Maybe some exposure. But mostly because
we've found competitions like this to be a lot of fun.

==


More details can be found at http://www.djangodash.com/. We will keep
it updated as things develop. If you're interested in competing in the
Dash, we'd appreciate if you'd fill out the mini-email form on the
front page so we can get an idea of how many people are interested.


How can I help out?
The Dash is really missing two things right now. First, we'd like to
have three fair judges signed on to help judge the apps once the
competition is over. Second, we're looking for sponsors who can
provide prizes as awards. No minimum/maximum dollar value is
required/requested. More details on this can be found at
http://www.djangodash.com/sponsors/.



Thanks and hope to see some of you competing!

Re: Images and Stylesheets

[Justin Lilly]

You're problems are one and the same. It seems you're runserver isn't
configured to serve images. The bit of code you're looking for is:

if settings.DEBUG:
urlpatterns += patterns('',
(r'^site_media/(?P.*)$', 'django.views.static.serve',
{'document_root': '/path/to/media'}),
)


where /site_media/* is the path of your files. So if you have master.css
that lives in a css folder in /path/to/media, you'd reference it as:

/site_media/css/master.css

similarly, if you have an img directory under site_media, you would
reference your images to /site_media/img/foo.jpg

You will also want to look into setting up the MEDIA_URL for your
settings.py file. I would suggest:  'http://localhost:8000/site_media/'

Now instead of referring to your css file as:

/site_media/css/master.css

you can now refer to it as

{{ MEDIA_URL }}css/master.css

which should ease the pain of migration when your media might not live in
/site_media/

for more info, check out
http://www.djangoproject.com/documentation/static_files/

I'm not sure if you were asking but "Serving static media" basically means
"Tell runserver it can find my images _HERE_" where _HERE_ is defined in the
code snippet above.

Hop on by #django on irc.freenode.net if you have any more problems (or just
reply here).

Images and Stylesheets

[Greg Lindstrom]

Hello Everyone-

I started learning Django at PyCon in Chicago and have worked most of the
way through the "Django Book" and Sams "Teach Yourself Django", as well as
"Head First HTML with CSS and XHTML".  It's been quite a lot for this old
dog, but I'd like to take a crack a writing my own web site using Django.  I
have two problems, and I think they are related.  The first is how to get
images in my site and the next is how to use css.

I wrote Jacob about images and he was kind enough to point me to
documentation on how to get the web server to "serve" the images.  I hate to
put it this bluntly, but I don't know what that means (I've been programming
database applications for 20 years and all this web stuff is still pretty
new to me).  Is there something that explains to someone like me how to get
images into the site?  Though I'm running Django on my Ubuntu laptop, I
would like to eventually have it hosted.  I would like to know how to "do"
images locally, then what I need to do when I host my site.

The other problem is getting css to work with my site.  I have set up a
base.html template (I love the templates, thank-you) and extend it with
other templates, call one greg.html.  The html generates just as I expect it
to (overriding blocks just as it should), but it doesn't "see" the style
sheet.  One it gets "in" the template I'm OK; the "Head First" book did a
pretty good job explaining it.  I even put a syntax error in my view  so
Django would list out the settings, but couldn't find where Django is
looking for the css file.  I suspect it is a similar problem to the images,
but I just don't know.


Thanks for your help,

Re: Has anyone made an MS excel exporter in a django site yet?

[Rock]

While I have used Django to emit csv files, I have also found
that my users are quite happy at times with simply cutting and
pasting data that I display in HTML tables via Django directly
into their spreadsheats. You might want to see if this is an
adequate option for some of your use cases. It has worked out
suprisingly well for some of my users.

I can't believe that no one has mentioned the xlrd package:

Then again I haven't used this one yet, much less tried to incorporate

alternative to (r'^house/edit/(\d+)/$',ediHouse)?

[ydjango]

I am displaying a list of houses and on clicking on one of the houses
I want to show/edit details

currently I am using constructing url as /house/edit/123/
where 123 is house data base primary key for that house.

Can exposing the primary key in url be any security issue?

(r'^house/edit/(\d+)/$',editHouse)

Is there alternative way without exposing the primary key in url?

Problems using feedparser and memcached in RSS model

[dpweb]

I have a model to store information about an RSS feed, which has the
method:

def refresh(self):
 dict = feedparser.parse(self.feed_url)
 # Do some processing


and a view:

def refresh_rss(request, rss_id):
  rss_feed = RSSFeed.objects.get(pk=rss_id)
  rss_feed.refresh()
  # Extra processing

When I run the refresh function off of the shell, it works fine
regardless of memcached.  Also, when I access the refresh_rss view
with memcached disabled, it works fine.  However, when I access the
refresh_rss view or run the refresh function with memcached enabled,
it doesn't work.  In particular, it seems that the feedparser.parse
function is not actually running.  There are no error messages or
anything, dict just ends up being None.  Anyone have any ideas why
this might be happening?  I've tried everything I could think of, and
am nearly certain that either feedparser.parse or memcached is to
blame.  My only thought was that since parse takes some time to run,
memcached or django might impose some sort of timeout that stops
execution of slow functions, but I couldn't find any documentation of
anything like this.  Thanks in advance for any help whatsoever.

It's a bit of a more general question really, but does this sort of set 
up work OK, where you send '/' to django but have a sub-path of that 
served straight from the disk? I need to do something like this to serve 
my media files when I take my project live, but I was worried it would 
mean at some point having to create a separate IP address and virtual 
host to run a server on, rather than just serving everything from the 
same path.

Re: Django on plesk - Virtual Host

[Tim]

I've got a couple Django apps running on Plesk. It's not the greatest
but it works.

First, after you set up your subdomain, you'll need to create the
file:
/var/www/vhosts/ domain.fr/subdomains/django/conf/vhost.conf

Here's the contents of mine:
--
DocumentRoot /var/www/django_projects/myproject


SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE myproject.settings
PythonPath "['/var/www/django_projects'] + sys.path"
PythonDebug On



Options +Indexes
SetHandler none

--

In my set up, the media folder is all the images, css and js files.

After you create the file, you have to go back into the plesk control
panel and go into your subdomain and save it again (even if you don't
change anything). When you put the vhost.conf file in the directory,
plesk doesn't automatically load it so by resaving your subdomain
settings, you'll tell it to find the file.

I hope this helps.

Tim

Chicago Djangonauts list / meetings

I've started a Chicago Djangonauts list; apologies for the noise for
the 99%+ of you not in the Chicago area.  :-)

I'll be starting discussion soon about when and where our first
meeting should be (sometime in May); if we have enough interest, we'll
make it a monthly thing (probably during those weeks ChiPy isn't
running).

Re: unknown encoding: utf-8 error

[Cephire]

I hope this will be last one on this thread.
Now I am able to compile without any error and create an exe file out
of it.
I have hooked this with cherrypy (as I dont know how to hook the
development server).

When I open the browser, I get the below error:

ImportError: No module named backends.db

I've already imported db.backends.sqlite3 (which is what I use). So i
don't know how this is happening.

incase if needed, this is how I invoke freeze

FreezePython --target-dir=c:\sol sol.py -c --include-

Any help is appreciated.

Accessing data from previous steps in Form Wizard

Hi there,

I am developing a form wizard comprised of about 20 forms. Some of
those forms require access to the previous forms for validation. Is it
possible to pass user-submitted data from previous forms to subsequent
forms in a form wizard?

Thanks,

Re: tutorial question

[Erik Vorhes]

Using a database doesn't by default make your site searchable. It's a
more efficient storage system (usually) than having a bunch of static
files.

SQLite is an easy way to develop, especially if you're running Python
2.5, but I usually move to a PostgreSQL backend for "production"
sites, since SQLite doesn't allow for password protection of the
database.

Oh, and Django does most of the SQL heavy lifting for you, so it's not
as if you need to become proficient in it before developing something.
Just glance at the SQLite documentation, and when you're in your
database, make sure to type ".databases" (everything inside the
quotes) to see the path to your database, so you can put it in your
settings.py file.

Django API interface adapter for Google App Engine

[Siddhi]

Hi,

I'm working on an interface adapter for Google App Engine's datastore.
I've just started out and have created a project for it here with some
basic code - http://code.google.com/p/django-gae-helpers/

The intro page has an explanation of what I'm trying to do -
http://code.google.com/p/django-gae-helpers/wiki/Intro

And you can get the current code from the repository -
http://code.google.com/p/django-gae-helpers/source/browse/trunk/gaeadapter.py

It is released under MIT license.

So far a few of the methods have been implemented, basically those
that I needed to port one of my projects. I think it would be pretty
cool if we could adapt most of the API like this. Any thoughts?

Re: Catch-all route?

[Erik Vorhes]

Check out the documentation on URL configuration, if you need
something more customized than the default 404.html template. (You
don't need to write a special regex for 404 situations, but you could
just use, as the *absolute last* pattern something like r'^.*$' (I
think).

For the most part, floguy is right--you don't need to worry about
customizing this stuff. Just make an appropriate template.

Re: Catch-all route?

[[EMAIL PROTECTED]]

This is the default behavior.  If no pattern matches the URL from the
request, it will load and display "404.html".  This is assuming that
DEBUG=False.  If debug is set to True, then you will get a helpful
debug page.

Re: Link that performs an action

[Taylor]

Thanks, I'll definitely check that out.  The last time I did AJAX
stuff was a couple of years ago when it was the hot spanking-new thing
(even though it isn't new), so there weren't really any good libraries
out yet.  Thanks for pointing me to the serialization doc.

My other thought is to create a custom tag that automatically builds
the from with a hidden data in it, but I haven't looked into custom
tags to see if that's possible yet.

Thanks!

You're running into the autoescape tag, which is on by default in
templates. Check the template (for Python) docs to see how to mark
your filter as "safe".

Re: Application Concepts

[Erik Vorhes]

It doesn't necessarily hurt to have apps inside the project folder,
but it does make it harder to extract and reuse them.

If I remember correctly, you don't need much, aside from settings.py,
urls.py, and __init__.py.

Re: Loading ChoiceField in forms

[ydjango]

There is really no need to pass anything to __init__ in form

In view itself you can access the forms member/global variables. It is
python, so not much is private. unlike java.
(other way would be to create setter methods in form, if you are an OO
purist)

in the View itself, I added
 form = NewCaseForm()
 form.fields['owner'].queryset =
Participant.objects.filter(group__exact=my_group)

and it works. If I am missing some nuance which can cause issues later
on , please let me know.

Catch-all route?

[Brandon Taylor]

Hi Everyone,

Is there a way to define a catch-all route to send people to a 404
page? Obviously I need to define a route that matches anything not
previously defined, but am struggling with the RegEx to do so.

Help appreciated!

Re: Tricky newforms problem

[Brian Morton]

Thanks.  This works perfectly.

Is there a better way to implement what I am trying to do?

Also, does anyone know how I can capture these elements again in the
view when processing the form?  Since there are an arbitrary number of
fields for songs, I don't know how many I should be looking for in
cleaned_data.  Ideally, I need to capture the song ids that were
selected in some kind of iterable datatype, then loop through them and
look them up in the model to get info for output.

I think the rule is that every directory including and above the one you

the python path should have a __init.py__

As far as I know this doesn't apply to templates, just to .py modules - 
it's a python language thing not a django thing.

Nevermind, I am a moron, it should be

{% if forloop.counter|divisibleby:"2" %}

How to add other class attributes to Admin's fields attribute?

[[EMAIL PROTECTED]]

I have a class attribute decorated with the Property decorator.
But I can't add it to the fields attribute of the Admin class, because
it's not a Django field. The reason we want to add it is that we would
want it to appear in a certain order.

How else can I do it?

Thanks

how do I create a zebra table using a template?

[Chas. Owens]

I am a new Python and Django user, but I have a good deal of
experience in other languages.  I am trying to create a zebra table
(alternating colors for list items or table rows).  The way I would
normally go about this is


{% for greeting in greetings %}
{% if forloop.counter % 2 %}

{% else %}

{% endif %}
On {{ greeting.date }},
{% if greeting.author %}
{{ greeting.author.nickname }} 
wrote:
{% else %}
an anonymous person wrote:
{% endif %}
{{ greeting.content|escape }}

{% endfor %}


But, of course, the if statement can only test a variable for truth.
Is there a way to do this in the template, or am I going to have to
resort to stupid JavaScript tricks?

You are not supposed to access the script directly like this.  Rather you
are supposed to use your application's normal urls (e.g.
http://www.muicscharity.com/admin/ for, say, the Django admin app), and the
RewriteRules convert that to an invocation of your dj script.

CGI is not at all a recommended way to run Django (see the discussion in
http://code.djangoproject.com/ticket/2407) but it seems it can be made to
work after a fashion if it's your only option.

Django on plesk - Virtual Host

[martyn]

Hi,

I'm just copying my django project on my Fedora-Plesk server and
something is missing in my mind.
All my projects are Virtual hosts.

My main domain :
domain.fr

My django project :
django.domain.fr

And my medias :
medias.domain.fr

On plesk, you cannot write directly on the httpd.conf because it's
overwriten by plesk itself, you have to add other vhost.conf files on
each subdomains.

Plesk did that for me into the httpd.conf file :


ServerName   django.domain.fr:80
DocumentRoot /var/www/vhosts/domain.fr/subdomains/django/
httpdocs
CustomLog  /var/www/vhosts/domain.fr/statistics/logs/
access_log plesklog
ErrorLog   /var/www/vhosts/domain.fr/statistics/logs/error_log

SSLEngine off



php_admin_flag engine off


php_admin_flag engine off



SetHandler python-program
PythonHandler   mod_python.cgihandler


Options -Includes -ExecCGI



I'm not allow to modify this file.
In my own vhost.conf, what do I have to write ?
I tried this (and other derivated from 
http://www.djangoproject.com/documentation/modpython/)
:


ServerName django.domain.fr
SetEnv DJANGO_SETTINGS_MODULE myproject.settings


With no success.
I really want to improve my knowledge into Django Deployement on
apache.
Thanks in advance.

Martyn

Re: Is middleware appropriate for this?

[Panos Laganakos]

Thanks for the link Chris, but this is not what I'm trying to do. I'm
not worried about the way the price look, but the price currency
itself. Since the user is allowed to select that per session.

If there's a way for a filter to access the session variables I would
be OK, since instead of multiplying with the currency passed to the
filter like the post above (product.price|currency:"EUR"), I could
just do product.price|session_currency or something and have the
filter return the price multiplied with the session's currency.

Re: unknown encoding: utf-8 error

[Cephire]

Thanks Karen. It helped. But I got another error.

AttributeError: 'module' object has no attribute 'admin'. Searching
through the net, I found that __init.py__ should be present in the
directory. It does have __init.py__.

Should all directories (like media, templates) have __init.py__?

As I said before, this works fine in development (using the django
server) and production server too(apache+mod_python).

Thank you,
Joseph

If num isn't in the URL and it isn't a GET/POST parameter, where is it 
coming from?

For front end of AJAX, use whatever Javascript lib/code you like, Jquery 
is my choice. Django doesn't come with or dictate a particular one.  The 
back end, Django part, of AJAX works exactly like any other view but 
return JSON or XML data instead of HTML.

def my_view(request)
data = simplejson.dumps(Model.objects.filter(somefilter=whatever))
return HttpResponse(data, mimetype="text/javascript")

Re: Django.cgi on Linux Hosting

[Aldo]

Fair point.

My problem is - Initially i created my index.html in the root(DOCUMENT
ROOT).
Now I have downloaded Django as described - put it in my root.
I have created my .htaccess files as
RewriteEngine on
RewriteRule ^cgi-bin/ - [L]
RewriteRule ^media/ - [L]
RewriteRule ^(.*)(/)$ cgi-bin/dj/$1/
RewriteRule ^$ cgi-bin/dj/home/
Ive created the cgi-bin/dj file and gave permissions.
However when i try to access that file(http://www.musicischarity.com/
cgi-bin/dj) it gives me an error -  Error 500: Internal Server Error
(Usually I would have content-type in it - but its not in the
examples. tried it and still no good.)
The dj file was edited to contain my own details. paths etc. maybe i
have them wrong.
sys.path.append("/hsphere/local/home/musicisc/Django-0.96")

Re: Is middleware appropriate for this?

[Panos Laganakos]

Dan, I don't think context_processors will do any good, since I'd have
to load each product and its price on the context.

imagine a model:

Product(models.Model):
price = models.FloatField(...)

and a

Currency(models.Model):
code = models.CharField(maxlength=3) # USD, YEN, etc
factor = models.FloatField(...) # defines the difference to euro

and in a template I do:

{% for product in product_list %}
{{ product.name }}
{{ product.price|currency:"EUR" }}
...
{% endfor %}

All that does, is take the product price and multiply it with the
currency's factor.

I've already set up a context_processor which registers CURRENCY,
which the user can set his preferred currency (EUR, USD, etc).

But since I cannot do {{ product.price|currency:{{ CURRENCY }} }}, as
only strings are allowed, and filters don't have access to context
variables or the request session, I am wondering if middleware is the
answer here. But I have no prior middleware experience :)

Maybe a template tag would do it, not sure if it gets access to the
request.

You provide links to two sites with detailed instructions on how to do what
you are interested in, but no details on what trouble you have run into
trying to follow those instructions.  It's rather hard to provide any
guidance with no clues as to what isn't working.

Re: Using form wizard to complete form over multiple sessions

[Honza Král]

if you are using the wizard class, it doesn't remember the state
anywhere, so if you supply the correct POST data, you will get thrown
exactly to the point you wanted to be. The only thing you have to do
is save the form data somewhere (perhaps just pickle the POST in a
database), retrieve them later and create the form (see Wizard.render
and render_template how the data is passed to the template).

hope this helps

It would seem you have to explicitly tell cx_Freeze what encodings your
program is going to need.  See this thread on the cx-freeze-users mailing

Not a middleware, but a context processor.
http://www.djangoproject.com/documentation/templates_python/#subclassing-context-requestcontext
You write a function that takes a request as an argument (therefore
giving you your session) and returns a dictionary of items to be
merged into the template's context, which is of course available to
your template tag.

Re: Overwriting RSS item links

[Ian Lawrence]

Hi

you could do something like in settings.py:
ROOT_URL = whogotmassive.com

and in your feed.py:
link = "%s/balls" % settings.ROOT_URL

the challenging thing for me now is trying to use the
request.META('HTTP_HOST') variable as the ROOT_URL to prevent this
extra configuration setup step in settings.py and the need for the
sites table setup in the admin. I believe this is possible in svn
using RequestSite but i need it working on 0.96. I am thinking call
some template to get the variable and pass it back into the view but i
have not yet fully thought out the technique...any advice is obviously

Re: Two sites, one django project

[andy baxter]

Hello,

I've been thinking about this - probably the best way is if you can find 
something built into django (like the i18n framework) which will do 
this, but failing that you could try this:

- for the templates, just have two sets of templates, one for each site.
- for strings that are written into the python code, you could do it by 
defining a file (call it 'site-strings.py'), which looks something like 
this:

site_strings={
'search_error': 'There is an error in your search parameters',
'search_help': 'Enter a title of a video to search for',
...
}

Then in any file where you need to generate hard coded strings, instead 
of putting the string in directly, first import site-strings.py, then 
refer to the string from the site_strings dictionary.

If you want to have the same django instance running both sites, you 
could adapt the above by expanding the dictionary to include a 
sub-dictionary for each word:

i.e.:

site_strings={
'search_help': {
videosite: 'enter a title of a video to search for',
   musicsite: 'enter a title of an album to search for'
   }

}

The only problem (I can see) with this method is it might make it hard 
to later on add i18n alternate language functionality to your code using 
the django framework for that.

I think you're suffering from very severe conceptual confusion.

Take a podcast and think about it logically:

Each podcast has a name.
Each podcast has one or more "authors".
Each podcast has one or more "episodes".

Each "episode" has a publication date and an audio file, and maybe
some other metadata.

The logical way to build this, then, is to set up database tables
which store this information, and then query it to dynamically
generate an up-to-date feed, and that (modeling data for storage in a
database, inserting it through a web-based interface, querying it back
out again and rendering it into the output format of your choice
through a templating system) is what Django is good at.

Is middleware appropriate for this?

[Panos Laganakos]

I've written a currency filter that takes the 3 letter code of a
currency and gives you the price.

{{ product.price|currency:"EUR" }}

There's a context variable called CURRENCY which specifies the current
session's currency.

I'm not able to pass that variable in the filter itself instead of a
string, so I'm curious how to make this happen.

I don't want to do it in the model level (maybe defining a OneToMany
with each currency to price), so I'm wondering if working on a
middleware, `process_view` or something would be the right place to
make the conversion.

Troubles with JavaScript localization

[Peter Melvyn]

Hi all,

perhaps I've missed something important in my very-beginning with
Django, because I encouter a problems with JavaScript localization.

1. I serve .js as a static files directly by Apache, so they reside on
MEDIA_ROOT out of project/apps folder tree

-> I cannot build message files. I need to move .js files among
remaining source files and do manual deployment of those files
into proper location on MEDIA_ROOT

2.  Once .js moved, I can build them into myproject/locale/ folders,
 by I cannot refer them from templates - if I enter 'myproject', it does
 not work. I have to move locale folder into next level, eg.
 'myproject.myapp' to be found.

###

ad 1. What is a recommended way to manage .JS files in Django projects?
ad 2. Is there a way how to refer project level locales or they can reside
  just on application level only?


Thanks, Peter

You'll be wanting a database, that's where the models store their data.
If you don't want anything too complicated, sqlite would probably be the
easiest to set up (depending on what OS you're using etc).

If your template looks something like:

  {% for field in form %}
{% if field._is_song %}
...

then the for loop 'field' is actually a boundfield instance which
wraps the real field. To get to the real field use 'field.field' in
the template. I.e. your template would look like:

   {% for field in form %}
 {% if field.field.is_song %}
...

Re: middleware that works with Ajax

[Chris Hoeppner]

Russ for president!

This is actually one of the big reasons to prefer django over and above
so many other frameworks. Take rails for example. You *can* use whatever
js stuff you fancy, but if you don't use *their* stuff, you're giving up
on much of what the framework offers.

Re: app engine db backend project

[Chris Hoeppner]

I've been looking into this too last night. Though I never before looked
into a backend and I'm not on qsrf branch, after looking into the
trunk's backends, I can tell that they're a tad over my head.

It's a shame that this is not documented (though I'm not whining at the
devs for not writing it, I recon there are more important things to do
than document maybe-unstable low-level components).

If I can do anyhing to help, I'm in.

Though I do not always use a reusable app, even if it exists, (leaky

Re: Annoying little bug that just won't stop -- new forms admin

[Dan]

I Just had a problem with this and it came down to the PIL component
on my server not having jpeg support, maybe try installing libjpeg and
rebuilding and installing PIL.

Overwriting RSS item links

[Matt Davies]

Hello everyone

I have a need to overwrite the item_link of my rss items in my feed.

I'm using the item_link method described here.

http://www.djangoproject.com/documentation/syndication_feeds/

If I use this code

def item_link(self, obj):
return 'balls'

and my site url in djangoadmin  is whogotbig.com

the link that is created for each article is

http://whogotbig.comballs

Is there any way I can change this behaviour as I need to overwrite the URL
completely to something like

http://whogotmassive.com/balls

I can't change the name of the site in django admin as that would break
everything else.

Any tips or advice would be gratefully welcomed.

matt
