What is your wsgi web server?  Specifically, what current directory does it
have when running?  If it is not the same as your project directory where
you are running the syncdb command, the web server won't be able to find the
database file since you have not specified a fully-qualified path to it in
settings.py.

Capturing Web Page data to a File

[Hrishikesh Dhayagude]

Hi,
In my application I've opened a file and displayed its contents on the
web page. Then I edit the same file on the web page. I have completed
till this. Now I want to store the entire new contents which are
currently on the web page back to some file.
In short I need to capture the entire data contents on the web page
into some file. So can anyone please tell me how this can be done??
Thank you in advance.

Regards,
Hrishikesh Dhayagude

"Cannot execute the specified program" generally means the system can't find
some DLL needed for the program.  Django doesn't have any DLLs, so I suspect
your python installation may be the cause of the problem.  Can you run any
python program?  For example if you create a hello.py file with contents:

print 'hello'

Can you run it?

Re: Can all of unicode be slugified?

When in doubt, look at the source. The 'slugify' template filter is
implemented as, well, a template filter, and so lives with all the
other built-in filters in django.template.defaultfilters:

http://code.djangoproject.com/browser/django/trunk/django/template/defaultfilters.py#L222

It's easy to see from the code what's going on. A Unicode string comes
in to the filter, and is normalized (using form NFKD) and encoded as
ASCII, ignoring non-convertible characters. Then any character which
is neither a space, a hyphen nor an alphanumeric character is
stripped, as is leading and trailing whitespace. Finally, spaces are
replaced with hyphens.

The result is something which will be usable in a URL, regardless of
the exotic characters which went into it. However, this does have the
possibility of discarding information, in a couple of places.

First, the Unicode normalization and ASCII conversion is important --
NFKD decomposes characters, and then the ASCII encode discards
anything that can't be converted. So, for example, if the character
'ñ' is in the string, the NFKD normalization decomposes it into 'n'
and a combining diacritic, and then the ASCII conversion with the
'ignore' flag discards the diacritic. For a URL, this is typically
what you want, because it means 'ñ' becomes simply 'n'.

The other place where you can lose characters is in discarding
non-alphanumeric characters, but again for a URL this is typically
what you want.

Can all of unicode be slugified?

[W.P. McNeill]

I am writing a Django application that uses characters from the
International Phonetic Alphabet (IPA).  I am trying to type the IPA
characters into the admin interface and have Django automatically
prepopulate a slug field.  Django is ignoring the IPA characters.

Is this expected behavior?  I can see some discussion on the web that
references unicode support for slugification, but I can't tell if that
unicode support works for any arbitrary unicode characters, or Django
has hand-crafted slugification for certain non-ASCII characters (e.g.
common European characters).

If the latter is the case, I will have to IPA slugs from something
other than the IPA characters because these are probably too obscure
to ever be included in Django API code.

Is slugify available as a Django API call?

[W.P. McNeill]

I am going to populate the tables in my Django app from .CSV files
rather than through the admin interface, so I am going to need a
slugify Python function.  I could write my own or pull a snippet from
the web, but this seems error prone.  The right way to do it would
seem to be to use the slugify code that is already in Django.

This code must be in there somewhere because there is a slugify
template feature and the admin pages can prepopulate slug fields.
However, I don't see a reference in the documentation to a slugify
Python function that can be called from a Django app, and the fact
that I can find lots of Django snippets online in which people are
rolling their own slugify function makes me think that this function
is not part of the Django API.

What is the best way to slugify an arbitrary string using a Python
call?

Re: Newbie: How to use object related to dropdown selection in django/javascript spaguetti code?

[Tiago Serafim]

Hi,

First you should have an attribute "name" on your select. It's needed to
pass the value when the form is submitted.

If your select's name is "foos_combo", then your code you'll look like this:

def foo_relatory(request):

if request.method == 'POST':
foos_combo = request.POST['foos_combo']
return HttpResponse(foos_combo)

else:
return render_to_response('foo_relatory.html',
 {'title'   : title,
  'show_filter_foos': True,
 },
 context_instance=RequestContext(request))

Newbie: How to use object related to dropdown selection in django/javascript spaguetti code?

[Samuel Lerning]

Hello,

I'm a newbie struggling with a simple problem for some time now.
I know it is a simple problem and it is a shame that I don't know how
to solve it.

I have a django spaguetti code that, instead of using forms, uses
javascript functions to get a selection from a selection list
().

Since I have some deadlines, I'm thinking on use request.POST (saw
some
about it on results from google), but I don't know when, where an how
to use
request.POST to get the selection  and work on it on the view.

Basicaly, there are a Foo class on Models.py

And I need to get the selected "foo" object from the dropdown to,
then, list
data relatated to that foo in the same page.

The relevants parts of the code are the following:


>foo_relatory.html   (template)




{% if show_foos_filter %}
  
  Foo:
  
{% for foo in foos %}
  {{ foo.nome }}
{% endfor %}
  
  
  
{% endif %}

Re: Memory limits

It also depends on how OP deploys Django. Use embedding with

then you can be setting yourself up for problems. Read:

Because you haven't prefixed all your imports or module path

Re: Django Project Management App

[Greg Brown]

Cheers for the feedback folks. Just to be clear, my app doesn't handle
code repositories or bug tracking at all - it's very much a one-user
system at the moment. I actually just run it on my Macbook in a
terminal (applescripted on startup). It's somewhat similar to basecamp
I guess, albeit much simpler - per-project todo lists, time tracking,
and invoice generation are pretty much all it can do for now.

Anyway, once I've found some time to clean it up, I'll unleash it on
the world and see what happens...

Cheers,
Greg

Re: Editors of choice

[V]

After the hordes of happy Vim users around, I gave Vim another try.
I've tried to set it up for Django around half an year ago, but
finally gave up, and went back to heavy-lifting with Eclipse.

Today, I got much further then before, so I'll post what I've found
until now, and what I see as the main remaining problems. I would
appreciate any help, but it might be another topic.

My .vimrc file is at http://pastebin.com/f470926a

I installed the following plugins:
• django.vim: http://www.vim.org/scripts/script.php?script_id=1487
Usage: :setfiletype htmldjango
• taglist.vim: http://vim.sourceforge.net/scripts/script.php?script_id=273
Usage: TlistOpen
• tasklist.vim: http://www.vim.org/scripts/script.php?script_id=2607
Usage: \t
• omnicomplete: http://blog.fluther.com/blog/2008/10/17/django-vim/
Usage Ctrl+Space
• SnipMate: http://www.vim.org/scripts/script.php?script_id=2540 and
SnipMate for django: http://github.com/robhudson/snipmate_for_django/tree/master
Usage: Tab completion
• xmledit.vim: http://www.vim.org/scripts/script.php?script_id=301
Usage: >, >>, %

Moreover, created a ``djvim.sh`` to run vim with a given
DJANGO_SETTINGS_MODULE set, this is specific to my usual development
structure, so you might not like it, it's at http://pastebin.com/m3cd39bd5

What I miss / could not figure it out until now:
• have django.vim syntax set for every html file by default
• have shortcuts to run the server and unittest with optional django
application inside vim
• have shortcuts to other commands, like ``shell_plus``
• debugging with jump to code, especially when running ./manage.py
test

I really like how fast Vim is, and omnicomplete, SnipMate and Taglist
made it comparable to Eclipse, while its syntax highlighting seems to
be even nicer. Still, I really miss the possibility of running
commands, especially django's tests, so if you have any ideas on this,
please share it with me.

Once you have read the tutorial, I started my repo on the server, then
git cloned it locally. When I finish doing any work locally, I git
push it back up to the server. The reason I started it on the server
first was because I'm behind a NAT so I don't have an external IP for
my dev machine. Can be done either way though.

We're acually using Cherrypy, so it would be quite easy to test and
check the performance. We'll post any issues we found.

Deploying with Apache: confused by odd PythonPath requirement

[Dan06]

I've 'successfully' deployed django in a development environment on
Apache2. While, I've got it to work, I'm
thoroughly confused by the PythonPath setting needed for it to work.

I don't understand why I need to give the directory that contains the
django 'project' AND the directory that contains the django
'application' (see PythonPath below), since the directory that
contains the django 'project' also contains the django
'application' (see directory structure below).

Anyone know why I need to specify both 'project' and 'application'
directories?

PythonPath "['/var/django_projects/', '/var/django_projects/test/'] +
sys.path"

Directory structure:

var/
| django_projects/ <--- General directory for all django work/projects
| | test/ <--- Django project directory created by: django-admin.py
startproject test
| | | test_app1/ <--- Django app directory created by: python
manage.py startapp test_app1

Running Django on Tornado's HTTP server

[Bret Taylor]

I am one of the authors of Tornado (http://www.tornadoweb.org/), the
web server/framework we built at FriendFeed that we open sourced last
week (see http://bret.appspot.com/entry/tornado-web-server).

The underlying non-blocking HTTP server is fairly high performance, so
I have been working this weekend to get other frameworks like Django
and web.py working on Tornado's server so existing projects could
potentially benefit from the performance. To that end, I just checked
in change to Tornado that enables you to run any WSGI-compatible
framework on Tornado's HTTP server. You can find it in a class called
WSGIContainer in our wsgi.py:

http://github.com/facebook/tornado/blob/master/tornado/wsgi.py#L188

You will have to check out Tornado from github to get the change; it
is not yet included in the tarball distribution.

Here is a template for running a Django app on Tornado's server using
the module:

import django.core.handlers.wsgi
import os
import tornado.httpserver
import tornado.ioloop
import tornado.wsgi

def main():
os.environ["DJANGO_SETTINGS_MODULE"] = 'myapp.settings'
application = django.core.handlers.wsgi.WSGIHandler()
container = tornado.wsgi.WSGIContainer(application)
http_server = tornado.httpserver.HTTPServer(container)
http_server.listen()
tornado.ioloop.IOLoop.instance().start()

if __name__ == "__main__":
main()


I have only done very basic tests using the new module, so if any of
you are interested and start using Tornado with your Django projects,
please let us know what bugs you find so we can fix them. Any and all
feedback is appreciated.

Re: Date Field in ModelForm

I'd guess that the problem is the auto_now_add. When that's set, the
field is not editable (because the date can only be set at creation).
So the field is by default excluded from the form - but you've
explicitly stated you want that field showing, hence the error.

So there is probably a bug, but the bug is that it should raise an
explicit exception when you try and add a non-editable field to a
form.

New Django-based open source project - CCI:U Open Course Labs

[Daybreaker]

Hello,
I'm going to introduce a new Django-based open source project.

It is a web application that interfaces cloud-computing infrastructure
as course labs which can be used by students and professors in
universities. We are in still in very basic level, but with many
people's contribution, I'm sure that it could grow as a mature
project.

See details here:

Right, those are just libraries that provide API access over the
existing HTTP connection. If python hosting is enabled then there will
be no problems with those specific libraries. Asking customer service
about support for such will only confuse them because it's an
application level that's completely irrelevant to their service.

This is a presentation issue, rather than a query one. You just want
to get all the values, and group your output by entry id.

So in your view you do:
values = Value.objects.all().order_by('entry_id')

and in your template:
{% for value in values %}
{% ifchanged value.entry_id %}
{% value.entry_id %}
{% endifchanged %}
{% value.value %}
{% endfor %}

or something along those lines.

Development and deployment wit Git

[orschiro]

Hello guys,

I'm a single developer but since a VCS like Git has some really nice
features, like the history, I want to use it for my webprojects I'm
building up with Django.

But there are still some points I don't understand.

How do I have to set up Git?

Where do I start the repository - on my local machine or on the
server?

I think it makes sense to have it on the local machine as I'm
developing only for myself, but how do I get the project with its
changes on my server?

Very confusing. Thank you in advance. :)

Re: html template usage

[Peter Bengtsson]

Suppose you have a template called monster.html that looks like this:



   Company name
   
Lorem ipsum
   



Then, create a Django view and make it render a template called, say,
home.html which you make to look like this:

{% extends "monster.html" %}
{% block title %}My Company!{% endblock %}
{% block content %}
Welcome to my website
{% endblock %}

Now, in the same directory as home.html you now need to turn your
monster template into a Django template so change it to this:



   {% block title %}{% endblock %}
   
{% block content %}{% endblock %}
   




The rest is easy: Plain and simple reading of the Django docs and
tutorial.

Re: filter on entries from a certain user

[Peter Bengtsson]

I dont know what db.UserProperty() is but my guess is that that's
something related to the model.
Your form doesn't understand that so it defaults to None.
If you omit the field owner from the form, perhaps the form won't
attempt to fiddle with this and then the model is allowed to do it's
magic.
Something like this:

class ContactForm(forms.ModelForm):
class Meta:
model = Contact
exclude = ('owner',)

Re: Memory limits

[Peter Bengtsson]

Hard to say as it depends on your app but can't you just run the app
on your laptop and see how much memory it takes up when you run some
basic stresstests.
Django is quite close to pure python but when you extract large lists
of model instance objects into lists it can push the memory
consumption.

Re: post_save signal to create the new user profile

[Peter Bengtsson]

Signals or no signals I think your profile model is wrong. By making
it a subclass of User you're effectively getting all the fields of the
User model.
Write your profile model like this instead:

class Employee(models.Model):
user = models.ForeginKey(User)
address = models.CharField(...)
...

Re: File Field max size and admin interface

[Peter Bengtsson]

One way of doing it, and to be honest the only one I know, is to set a
limit in the fronting web server.
In Nginx for example you add:

  client_max_body_size 10M;

Sadly this means that if a user tries to upload a 11Mb file you won't
be able to confront them with a user-friendly "error" message.

def user_post_save(sender, instance, **kwargs):
Employee.objects.get_or_create(user=instance)

models.signals.post_save.connect(user_post_save, sender=User)

Now i get

IntegrityError at /admin/auth/user/add/

post_save signal to create the new user profile

[Dmitry Gladkov]

Hi!

I've got user profile, that uses multi-table inheritance:

class Employee(User):
address = models.CharField(max_length=50, null=True, blank=True)
phone1 = models.CharField(max_length=15, null=True, blank=True)
phone2 = models.CharField(max_length=15, null=True, blank=True)
skype = models.CharField(max_length=32, null=True, blank=True)
website = models.URLField(null=True, blank=True)
comments = models.TextField(null=True, blank=True)

When I create a new employee from django admin interface it creates a
new user for it, but how to manage to create a new blank employee
profile after creating a new user from django admin?

I tried to use post_save signal for it, but have no idea how to create
a new employee when it's inherited from known user.
When i use "instance.employee" it says "Employee matching query does
not exist."
When i try to create new employee using Employee(user=instance).save()
it says that there's no field called "user".
Thanks!

Re: How to server static media secured by Django authentication

[Lars Holm Nielsen]

Hi,

There's a couple of ways to do this, but none of them is really as
easy as using basic/digest authentication in apache.

Most of the methods posted until now passes the static file through
django or at least python, which might not be ideal depending on your
performance requirements.

Anyway, here are two more methods:

1) Use lighttpd with mod_secdownload (http://redmine.lighttpd.net/
projects/lighttpd/wiki/Docs:ModSecDownload). On the page there's an
example how to do it with django. Basically you just generate a token,
that only you django app and lighttpd server can generate. Bad thing
with this method, is that you don't have constant URLs.

2) Use Apache + mod_auth_tkt. mod_auth_tkt is a lightweight module,
that works nearly the same way as mod_secdownload. It just puts the
token in a cookie and can associate some strings with it (like user/
group etc). Then in apache, you just use a htaccess file to protect
your resources.

Other more complicated things you can look at is single sign-on
solutions for your webserver and django, but it usually starts to get
really complicated.

Cheers,
Lars
