This is an example about how to register a delete signal to save the
deleted user to a table called Eliminat, save should be nearly the
same.
You can put the in your models file, but be sure you have the
application model in the settings.py file.
{{{
def registra(sender, **kwargs):
# get the instance
instancia = kwargs['instance']
# Creates the object who's going to store the username
usuari = Eliminat(user=instancia.username)
# and the save it
usuari.save()
pre_delete.connect(registra, sender=User)
}}}
Hope it helps!

I have such a problem once and it was solved adding the application in
the config file.
On the other hand, I assume you have extracted the translation strings
and you're using the right language in your browser, that is the
language on which you want the pages or you have managed yourself to
change the languaje.

Re: Best IDE for Django and python?

I have tested Komodo Edit and personally I like best vim + extensions, Eric4, Eclipse + pyDev or actually Netbeans. I you haven't tested yet give Netbeans a look. In my opinion this is the way to go on Python development. Eclipse+pyDev and Eric4 actually have more Python options, specially on refactoring, but Netbeans interface is much clearer and the combination of auto completion and documentation is really good. I also like very much the svn diff tool with syntax highlight. Eclipse and Eric4 have a more svn interface. From Netbeans I don't like that the auto completion shows all the packages that are in the project even if they aren't related to it, and that it shows the pyc. But I have been testing it during the last days and even with this lacks it's one of the best IDEs. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: MySpace clone using Django? Is it possible?
A clone lot of sense if is very specific. That is, you can have a Facebook/MyEspace/whatever clone for example in your own company (think in a company with 1000+ employees in diferent locations) where you can provide an interface that some people could be familiar with. This was once a time called an Intranet, but now has evolved to the put-your-company-here social network. As this kind of application usually needs to get/save data from legacy systems, in my oppinion is better to buid the solution agains components, like Pinax does, so you have more chances to adapt the application to your users and company needs that getting a pre-built solution and just change the css. -- Antoni Aloy López Blog: http://trespams.com Site: http://apsl.net --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I not fully understant what you're trying to do, but with the initial
parameter on the form instance you have the chance to prepopulate the
form with data which is not going to be validated at that moment. So
on the template it's just a matter to write {{form}}
Hope it helps!

You can create a tag, depending on how your application is could make

Just prototype and test the performance for each.
For one of my applications I found that lxml+mako templates was the
best solution for me, but perhaps it's not your case.

templates tags has the for tag that allow you to iterate throught
collections, so you have to rethink your logic to pass the data in a
way that could be iterated and presented in the way you want.
So just pass to the template the list wicth contains the fnal data.

Test your Ajax URL agains the view directly with the browser. It's
seems there is some kind of problem there.
view: def test_1(request, zipcode, pro):
url (r'^ajax/test_1/(\S+)/$', test_1)
At firsth sight they don't match with
http://127.0.0.1/ajax/test_1/' + zipcode + '&' + pro +"/"
Try:
url = r'^ajax/test_1/(?P\w+)/(?P\w+)/$ ...
and
http://127.0.0.1/ajax/test_1/' + zipcode + '/' + pro +"/"
Hope it helps!

After a post you should use a HttpResponseRedirect(url). If you need
to have access to the post parameters an option is to save them in a
session, or encode them in the url itslef.

Yes, but you can't do it this way.
Just check for httplib and httplib2.
http://code.activestate.com/recipes/146306/
or from Python documentation in http://docs.python.org/library/httplib.html
>>> import httplib, urllib
>>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0})
>>> headers = {"Content-type": "application/x-www-form-urlencoded",
..."Accept": "text/plain"}
>>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80")
>>> conn.request("POST", "/cgi-bin/query", params, headers)
>>> response = conn.getresponse()
>>> print response.status, response.reason
200 OK
>>> data = response.read()
>>> conn.close()
Hope it helps!

At least in our LDAP configuration, there are restrictions about the
kind of queries that a user can do. So check also this. Use your
account to see if you can log in, and try to run the function step by
step inside the shell.
I you don't have restrictions on your LDAP the most commont issue is
with the LDAP base tree. That is where the user tree resides in your
organization. Use the step by step debugger to know if you can connect
to LDAP and check if there is aproblem just with LDAP configurations.

project is the name of your project, isn't it? You have to remember to
include the url for the translation javascript as
the documentatios is well explained.
On the other hand, I have experienced some problems getting the
javascript keys from the templates. The workarround I have found is to
have all the javascript (or nearly all) in external js files, a best
practice anyway.

Re: Django and ZSI
2009/8/31 Julián C. Pérez : > > Anyone has experience with using web services in Django?? > I mean, not necessarily with ZSI but others methods... > Yes, we have many of the working. But this is no a Django issue is more a Python programming one. You can access to Soap web services using ZSI, SUDS, Soappy or whatever you like to use. Isolate the web service client and use the parts you need. We have worked with ZSI mainly, but actually we're moving to Suds. To act a a server we prefer to simplify and we're using xml over http or REST services.

I would add surronding the table code, but I can't see
any problem. Please post the error. In my oppinion you'll have to
check the dataarray as it seems that one of the rows in now a list.

Have you properly configured your MEDIA_URL to point to your Tornado
server instead of localhost:8000. I haven't made any test about
Tornado performance on serving statig files, but on production our
actual configuration with CherryPy in WSGI mode involves a nginx
server acting as a reverse proxy and serving the media files.
I use the configuration without nginx pointing directly to the WSGI
server just to make sure that all the media points to right server.
That is, that I have write all my media files as
{{MEDIA_URL}}/img/.jpg and so on.
Hope it helps!

We're using mod_python and we run two different sites. We have the can't adapt error at random basis. Once is produced in one site the other site gives the same error. I don't know if is related or not, but the only thing we have done is to update to the security patch of 1.0 version. Actually we have updated to the 1.1.2 version but the error still happens. Restarting Apache makes everythink running again, but after some time the error appears.

and in the django.po, I do have a translation
msgid "Hello World"
msgstr "xxx"
But it doesn't show up on the website, all the other translations
work, so I am wondering what am I missing

Re: Deployment hesitation after James Bennett's post, WSGI or ...?
Hi, WSGI is the best option. For that we're using ngnix+cherrypy (just the wsgi adapter) and it works like a charm. Recently we've start testing gunicorn as well, as the deployment is really easy. This kind of configuration allows you to reduce drastically the memory consumption, so you can deploy small applications on cheap vps. But programing Django is addictive and for sure you'll finish with a dedicated server :) Best regards, -- Antoni Aloy López Blog: http://trespams.com Site: http://apsl.net -- You received this message because you are subscribed to the Google Groups "Django users" group.

These are very good news. Perhaps with the title the question hasn't given the right attention. In my oppinion you should remade it to something like "RFC Django support in Eclipse using PyDev". Even with the high memory comsumtion of Eclipse, the combination Eclipse + pyDev is my first recommended option for Python and Django development IDE. I have to confess my actual IDE is Vim and one of the reason that makes me to made the editor change was the lack of support of Django templates and (the biggest one) the high machine requisites of Eclipse. Django templates shoud support Django tags and filters, HTML, CSS and Javascript, This is enougth. Code completion on Django tags would be a nice add on, but Eclipse templates is usually enought.

Some IT departments does not allow nothing but the technologies they know, and they can be as old as cobol or j2ee 1.4 + EJB, so ask first your potential institution clients what they have. Django and Python can support really big projects. In fact one of the thinks I like best in Django and Python is that they are scalable in hardware but also in people, compared with PL/SQL or other languages where the layer separation is not as clear than the Django one. It's really difficult to say if Django is the right technology for your project, but at least you can do your first prototype rally fast and test for yourself. -- Antoni Aloy López Blog: http://trespams.com Site: http://apsl.net -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django doesn't load css
the css should be {% MEDIA_URL %} but you have to be sure you pass the
RequestConext on your render_to_response method.
If you're are on the development server you have to add additional
urls to urls.py to serve static content.
Is explained in the docs, but I suppose some examples you'll be
better. I created some startup and example projects that I think they
would help you.
http://code.google.com/p/appfusedjango/
Check project and agenda, they are a good start. The examples are not
updated for 1.2.1 but they work.

Re: Flexigrid
Hi Ramesh,
I haven't work with Flexigrid in my projects, but I did it with jqgrid
and as far I can see is quite the same:
In the Flexigrid sample you have:
$("#flex1").flexigrid
(
{
url: 'post2.php',
dataType: 'json',
colModel : [
{display: 'ISO', name : 'iso', width : 40,
sortable : true, align:
'center'},
{display: 'Name', name : 'name', width : 180,
sortable : true,
align: 'left'},
{display: 'Printable Name', name :
'printable_name', width : 120,
sortable : true, align: 'left'},
{display: 'ISO3', name : 'iso3', width : 130,
sortable : true,
align: 'left', hide: true},
{display: 'Number Code', name : 'numcode',
width : 80, sortable :
true, align: 'right'}
],
buttons : [
{name: 'Add', bclass: 'add', onpress : test},
{name: 'Delete', bclass: 'delete', onpress :
test},
{separator: true}
],
searchitems : [
{display: 'ISO', name : 'iso'},
{display: 'Name', name : 'name', isdefault:
true}
],
sortname: "iso",
sortorder: "asc",
usepager: true,
singleSelect: true,
title: 'Countries',
useRp: true,
rp: 15,
showTableToggleBtn: true,
width: 700,
height: 200
}
);
So the idea is to replace the php url with a django one. ex. /ajax/countries/
That url must map to a view and on that view you have to obtain
(Country.objects.all() if you have such a model) and then return the
json that Flexigrid wants. You can see the json in
http://www.flexigrid.info/post2.php
So the real problem is to know how to map urls to views, and that is
clearly explained in the Django tutorial, and how to return json data
instead of html, which is covered in :
http://docs.djangoproject.com/en/dev/topics/serialization/
http://chronosbox.org/blog/jsonresponse-in-django?lang=en
http://stackoverflow.com/questions/414543/django-serialize-to-json
etc.
With jqrid I was able to map the Django model response directly to the
grid (well almost), but I don't know if this is possible in Flexigrid.
Anyway, you can create your own structure, fill it from the model and
then dump it to json.
Hope it helps!

Django template compilation
Hello! Today I have been benchmarking a Django template to PHP compilar called Haanga http://github.com/crodas/Haanga/ a development sponsored by meneame.net a Digg like spanish site. Ricardo has made some sort of benchmark http://gallir.wordpress.com/2010/08/13/haanga-vs-django-vs-h2o. With my own benchmarks, using just the template part, Haanga it's about 80% faster than Django. The post is in Spanish but you can see the results. I know template speed is not a real problem in most sites but I'm quite impressed abut Haanga speed. My feelings are that the examples as most benchmarks tends to show where the product shines (samples are using lots of loops) but I haven't found any similar project for Django or reasons about why Django does not uses the same approach. I can guess some of the reasons: maitanibility, work split between developers and designers, custom template filters, ... But I'd like to know other's thoughts. -- Antoni Aloy López Blog: http://trespams.com Site: http://apsl.net -- You received this message because you are subscribed to the Google Groups "Django users" group.

[Announcement] Vim for Python and Django
Hello all! In this list we have a recurrent thread: "What'ts the best IDE for Django and Python development?" trespams-vim is my try to answer this question for people who likes to have a very powerful editor and needs to have an editor which is able to run in the desktop as well as in a remote session. I have updated the previous version with delimMate and easytags, so actually you'll find: * Syntax highlight * Python autocompletion * Smart tabbing * Templates for Python, Django, js, html, ... (just try to edit a python file and press sbu + tab as an example) * Add/remove comments on multiple lines * Tabs * Surround * marks etc. etc. : This is a list of my favorite shortcuts http://code.google.com/p/trespams-vim/wiki/readme So, you'll find a collection of plugins and .vimrc settings that I have found very useful in my day-by-day work in Python and Django. http://code.google.com/p/trespams-vim/ Happy coding! -- Antoni Aloy López Blog: http://trespams.com Site: http://apsl.net -- You received this message because you are subscribed to the Google Groups "Django users" group.

>> >> 2010/9/27 João Rodrigues >>> >>> http://code.google.com/p/trespams-vim/ Well I'm a little biased towards vim after all I try to mantain the trespams-vim, but I have tested nearly all the IDEs that have been posted in this thread, and my conclusion is that no exists such a thing as the perfect IDE. It would depend on your work. For me vim is perfect as I have to write code in the desktop and also have to edit code in remote shells, so having just one common editor is perfect for me, as it allows me to master in just one editor. If you just need a desktop editor just try the one that fits better in your daily work, it could be as simlpe as gedit o kate or as bloated as Aptana. Just try and you'll find the best IDE *for you*. -- Antoni Aloy López Blog: http://trespams.com Site: http://apsl.net -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: What is the correct way to copy an object from one model to a similar model?
You can use also introspection if the number of attributes is high. http://stackoverflow.com/questions/3818825/python-what-is-the-correct-way-to-copy-an-objects-attributes-over-to-another 2010/9/29 Yo-Yo Ma : > I have two models that are identical in structure except one has 2 > extra fields.
