This 'magic function' is
self.__class__.objects.get(id=self.id).stuff
if self.stuff != self.__class__.objects.get(id=self.id).stuff:
do_this()

This way two django instances would be running, that is why I don't want to use that method. Another thing is, i am not sure, but sessions will not be same for user in django when a user logins in HTTPS(443) and apps would not be able to use that session to recognize user on http(80). I would check the session implememtation in Django, if PORT number too is considered in generating session-id. Is there any thing, like initiating the SSL just for login on port 80 than changing it. -=Ravi=- --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Use fields instead of base_fields : 1. class TestForm(forms.Form): def __init__(self, *args, **kwargs): super(ArrivalForm, self).__init__(*args, **kwargs) self.fields['somefield'].label = 'foo' somefield = forms.IntegerField() 2. class TestForm(forms.Form): def __init__(self, *args, **kwargs): super(ArrivalForm, self).__init__(*args, **kwargs) self.fields['somefield'] = forms.IntegerField(label = 'foo') ArrivalForm in 'super' should be TestForm second is better eg. if you're using i18n and defining a form and views in one file. Because if you use: ugettext as _ this will work in __init__ but not for a class attribute.

Django on MacOS X Leopard
When I install Django on Leopard, py files went into: /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ site-packages/django/ And template htmls, etc. went into: /Library/Python/2.5/site-packages/django/ This resulted in some weird behavior such as templates of contrib applications such as admin not being located. My patch for this was to create a symlink as follows: sudo ln -s /System/Library/Frameworks/Python.framework/Versions/2.5/ lib/python2.5/site-packages /Library/Python/2.5/site-packages and then install Django.

Re: Django on MacOS X Leopard
I keep both django versions/branches and projects at the same level. My directory structure looks like: django_gis django_0.97-pre etc ... Project1 Project2 etc ... I symlink then an apropriate django version from within a project as "django". This allows me flexibility in both switching python and/or django versions. Not sure if this is the best way to do it.

It looks - to my uneducated eyes - if this leaves open a potential race condition where the mtime field could yet be changed in the database by another process within the "decision time" of this method.

Nothing built-in, though this is a common need and will likely get added to the admin at some point in the future. In the meantime, you may want to check out http://www.djangosnippets.org/snippets/568/ -- it's a clever little hack to expose an ordering field in the changelist view.

Problems with Primary Key when I've copied a DB
Dear All, I've copied a MySQL db (using mysqldump) and then loaded it into a new DB. I've also altered the structure slightly (I've added 6 columns). However, the problem is that when I try and use the db to add more data, the primary key starts from 0 again. Since the number for the first current item is 1, the first item goes in ok, but the second gives me a key error. I've tried using the setting the table auto increment to a safe value using alter table_name AUTO_INCREMENT = 300 (there being 264 items in there already) but it doesn't work. I've also tried doing it with set last_increment_id = 300, and the db is happy, but django still counts from 0. Doing a direct insert in the DB (using mysql) works fine, and it auto_increments ok. It _seems_ as though Django is missing the fact that these keys already exist, which is why I get the clash. I'm using 0.96 (as I couldn't get the newer mysql module to compile). Any ideas?

Static content I serve from the built-in Apache, symlinking to the admin static stuff in the django package, and then my actual projects live in various places in my home directory.

I'm on the first django tutorial: http://www.djangoproject.com/documentation/tutorial01/ Got my sqlite database set up. Now trying to "run the command-line client for your database". I understand the way to do that is $ python manage.py dbshell I get an error message saying "No such file or directory". Googling for this situation, I find http://code.djangoproject.com/ticket/6338 Which says I need to Sqlite3. But I thought sqlite3 came along with Python 2.5. No? Any clues to what am I missing here? Need to install something else? Path problems? Generic newbiness?

Process1 does a 'dirty read': http://www.postgresql.org/docs/8.2/static/transaction-iso.html But you need to use transaction management. The read and write must be in one transaction. The edit form has hidden value which contains the current mtime of the model instance. If the form is valid, check if the mtime has not changed. If it changed, you need reload the form (All previous form input must be reset, otherwise the user can't see what the other person has changed).

Hello, > But I thought sqlite3 came along with Python 2.5. No? > > Any clues to what am I missing here? Need to install something else? > Path problems? > Generic newbiness? I don't think so. Anyway, it is as simple as installing package "sqlite3" on your Ubuntu. If it's already there, even better. You might also need the "python-sqlite2" package, which provide the Python bindings for SQLite 3 (yeah, the version numbers look confusing at first). I'm not sure how Django works with SQLite, but those are the steps I took when installing Trac (I use Django with MySQL). Shouldn't be much different, as both are written in Python.

Re: Newbie sqlite3 dbshell confusion
Hello, An unrelated note to your question... If you are using 0.96, you need to use the 0.96 docs. http://www.djangoproject.com/documentation/0.96/ The link you pasted assumes you are using the development version, which has some differences. My personal recommendation is to remove 0.96 and use django-svn. Just thought I'd let you know!

sudo under django or better solutions?
Hi, i'd like to make an application that should execute commands with permission that are not normally for www-data (eg: create user). Of course I know I could use sudo and execute the command via subprocess or similar. But it happens that the command is a python script so i'd prefer to use the python library directly. Is there any reccomanded way/ a sudo-module or similar? thanks in advance sandro *:-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

How to attach multiple images to a blog post?
Hello, I'm trying to write simple blog tool but I ran into some problems. I would like to attach multiple images to a post. Here's my models: class Entry(models.Model): title = models.CharField(max_length=200) date = models.DateTimeField(auto_now=True) body = models.TextField() class Photo(models.Model): entry = models.ForeignKey(Entry, edit_inline=models.TABULAR, num_in_admin=10) photo = models.ImageField(upload_to='photos/%Y/%m/%d', core=True, blank=True) Now, when I create very new Entry via admin, I can add 10 images, ok. So I add some. Then, when I would like to add another ones or to change the ones already in, it goes wild: all the pictures are deleted and it is not even possible to add anything. Please, any help? I read somewhere that perhaps edit_inline is broken or something, is there another way how to attach multiple images to a post via admin?

Re: Error Messages
The design pattern is a toaster popup. You can achive this using CSS
+ JavaScript, for example with jQuery. For example, you could use
this CSS to hide your message area:
.messages {
position:absolute;
z-index:5;
top: -300px;
left: 300px;
width: 250px;
margin: 0 auto;
height:150px;
padding: 10px;
opacity:0;
}
This will position the box outside the screen area, you can then use
jquery to detect if it's on screen, if a message has been passed to
the view:
function($) {
$(document).ready(function() {
$('.message').find(function(), {
$(this).animate({top: 10, opacity: 1}, 1000, function() {
$(this).animate({ top: -150, opacity: 0 },
1000, function(){
$(this).remove();
});
});
});
});
})(jQuery);
This will animate the message on the screen, and then remove it again,
and then remove it from the DOM.
Hope that helps

Re: Error Messages
Well im using that API for an error message already, it doesn't create a new box, but it lists the error underneath the form. I am going to have long lists of names that i would like to display in an orderly fashion, and listing them in a box with the error message seems like the best method to me, I just dont know how to possibly combine the listof names with a javascript pop up box other some other type of box.

What you have installed is the SQLite library and the Python bindings, both pieces come now included in Python 2.5 (if you were using an older Python version you would have to install Ubunto packages named libsqlite3 and python-sqlite3 or similar). But what dbshell does is to execute tue command line client for your backend (mysql for MySQL, etc,...) aleady configured to work with the database of your Django project, and for SQLite that command line client application is sqlite3 that in Debian/Ubuntu comes in the sqlite3 package: http://packages.ubuntu.com/cgi-bin/search_packages.pl?searchon=names&version=all&exact=1&keywords=sqlite3 Note the "A command line interface for SQLite 3" part. Install it using the package management tool of the distribution and try again.

trouble with mod_python configuration
I am trying to get a handle on how to configure django/reviewboard
under mod_python.
I want to setup reviewboard not in the root directory but a sub
directory say /reviews/
I saw the comment:
Note
If you deploy Django at a subdirectory -- that is, somewhere deeper
than "/" -- Django won't trim the URL prefix off of your URLpatterns.
So if your Apache config looks like this:
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonDebug On
then all your URL patterns will need to start with "/mysite/". For
this reason we usually recommend deploying Django at the root of your
domain or virtual host. Alternatively, you can simply shift your URL
configuration down one level by using a shim URLconf:
urlpatterns = patterns('',
(r'^mysite/', include('normal.root.urls')),
)
in the DJango book (ch20) but I haven't seen any other reference to
placing django apps deeper than '/'
This is my first django setup so I can only hope I'm on the right
path, anyway I have the following in my apache config:
===
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE reviewboard.settings
PythonPath "['/var/www', '/var/www/reviewboard' ] + sys.path"
PythonDebug On
===
reviewboard.settings contains the line:
ROOT_URLCONF = 'reviewboard.myurls'
and reviewboard.myurls conatins:
urlpatterns = patterns('', (r'^reviews/',
include('urls')), )
which is how I interpreted the comment about a 'shim URLconf' from the
book.
Given the above config if I ask for http://10.64.9.131/reviews/ apache
tells me:
'The requested URL /dashboard/ was not found on this server.'
so the python handler is working but I have a problem with the shim
URLconf or the 'REVIEWBOARD_ROOT'
I am confident this setup it just one step away from bursting into
life, if anyone can share a little experience I'd appreciate it...

A slug question
I have a blog that has a slug field that gets pre-populated from the title of the blog. I then use the slug name as a part of the url. eg - www.xyz.com/weblog/weblog-title-goes-here/. My question: what if I have a weblog title that is identical to a post that I made 3 years ago and I didn't realize it? when saving, is the slugfield smart enough to acknowledge that there is a duplicate entry. If so how would it correct the problem (www.xyx.com/weblog/weblog-title-goes- here-2/)?

You could use daemon mode of mod_wsgi instead and configure it to have your whole application run as the target user rather than Apache, then you don't have to worry about it at all.

I don't really like do give all power to a web application.

most popular adjacent tags
dear list, let's say i have many tagged items (eg images or bookmarks). if i select one of them, and then i select a tag of the item, i would like to find all the items with this tag (including the selected one) and make a histogram out of the tags of found items (exluding the selected one), ie to count and to sort how many times a certain tag appears jointly with the selected tag. for example: -- image: an apple -- tags: red, sphere, fruit -- image: a pear -- tags: green, fruit -- image: an orange -- tags: orange, sphere, fruit if i select the apple and then fruit the result should be *: sphere(2), red(1), green(1), orange(1) * i don't need the tags which are found only once, if that would speed up the things a bit i probably know that i need 2 classes (image, tag) comming from models.model and a many to many relationship from image to tag. the things i don't really know how to get done is the query. i would be thankful for any help! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Example maybe I created a gallery called 'The Rockies' but I only want Bob, Susan, and Tim to see it, Is this possible with the built in permissions? or would I have to create a table column similar to is_public = models.booleanField(). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Using mod_wsgi daemon mode you can actually run up multiple process groups running as different users. Each would run the Django application, but you can then configure specific URLs to be delegated to the different process groups. Thus you can control user rights down to the level of URL. If you want, you can still use embedded mode (ie., like mod_python) to run the bulk of your code and use the daemon process just for the restricted URL set. For example: Alias /media/ /usr/local/django/mysite/media/ Order deny,allow Allow from all WSGIScriptAlias / /usr/local/django/mysite/apache/django.wsgi Order deny,allow Allow from all WSGIDaemonProcess django-admin \ user=django-admin group=django-admin \ processes=1 threads=5 WSGIProcessGroup django-admin In this scenario, all URLs of the Django application except stuff under '/admin' would continue to run in the Apache child processes just like when using mod_python. The user that that code runs as would be whatever Apache is configured to run as. For URLs under '/admin', they would be proxied through to a distinct daemon process running as the distinct user 'django-admin'. Thus, using the Location directive, you can selective indicate which URLs execute code which needs to run as the user 'django-admin'. No changes are required to the Django application for this to work, mod_wsgi automatically handles all the differences between running in embedded mode and daemon mode for you.

Re: Admin page url reference problem
I had the same problem.
I think the problem is that you are referencing a non-existent (view)
function named 'viewer' in your urls.py. This wasn't a problem in
previous versions, but with the addition of the reverse url lookup,
non-existent views now cause problems.
What I gather is happening is that on the first (admin) request, all
urls and consequently views are introspected. Since one or more of
the views (defined in the urls.py) don't exist an exception is
raised. However, the results are cached and subsequent loading of the
page don't cause an error (but the links are now incorrect).
So check your urls.py and see if that clears up the problem.

Hi, I have had some problms installing Django in Windows XP. I have finally got it to work, in a fashion.

newforms is great for creating forms. I need something similar to generate a display form from a model.

If all you're worrying about is the public display and/or non-admin forms, it's fairly simple to do the necessary check in your own code based on data stored in the model object. Depending on the exact nature of the check, you might even be able to write a decorator to handle it for you.

Re: form for display, not edit
Yes, I suppose if you wanted you could create a custom form that added the attribute disabled to all of them, however I am not aware of any other way, someone else might be able to explain how to alter all the fields in the __init__ method but I'm not sure how.

Persistent data (other than sessions)
I have a view that works something like this:
def graph_search(request):
g = build_graph()
result = search_graph(g, some_parameters_from_request)
return render_to_response('template.html',{'result': result})
build_graph() queries the DB and builds the graph in memory, which
takes about 2 or 3 seconds. Note that the data structure built is
independent of the request. The request dependent part, searching the
graph, is much faster.
Is there anyway I can make g persistent? In other words, I want to
build it once, and then search that copy for each additional request.
I can't put the graph in the session, because it pickles them, and the
data structure uses some ctypes that can't be pickled. Also, the data
structure does not need to specific to a session. Any request could
use this data structure.
Any ideas?

newforms file-upload troubleshooting
I've been trying unsuccessfully to implement a file-upload form. I put up the code from models.py, forms.py, and views.py, as well as the form template code and the generated form html at . I'd appreciate and welcome pointers to where I'm going wrong. Relevant info... - When I add a file from the admin interface, all works as expected. The file name appears in the db table's 'name' field; the path 'test_uploads/filename' appears in the 'originalfile' field; and the file is actually uploaded to the 'test_uploads' directory. - When I add a file (using my own newforms form) via the 'Choose File' button, the file appears to be properly selected. When I 'Submit', the file name *does* appear as expected in in the db table's 'name' field. However, in the 'originalfile' field, only 'filename' appears (i.e. 'house_pic.png'), not preceeded by 'test_uploads/' as above -- and the file is not uploaded to the 'test_uploads' directory or anywhere. - I'm running version 6401.

Here's my current url conf (I've commented out everything else):
url(r'^(johndoe|janedoe)/$', 'translator', name="translator"),
url(r'^(johndoe|janedoe)/(?P[\w\d-]+)/$', 'entry',
name="entry"),
I would be using named groups on the first segment match, but named
groups and the | still don't seem to be working.
These two views accept their arguments like so:
def translator(request, translatorName):
...
def entry(request, translatorName, entryName=None):
I can't get {% url %} tags based on these views to work -- they fail
silently on most everything. Using reverse() to see what's going on, I
find that:
reverse('translator', args=['johndoe'])
Gets me the correct url, while this fails:
{% url translator johndoe %}
Looking into the url tag code, I don't see why that would happen. When
I try reverse() on the 'entry' view, like this:
reverse('entry', args=['johndoe'], kwargs={'entryName':'blogentry'})
I get this traceback:
Traceback (most recent call last):
File "", line 1, in

File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/re.py", line 233, in _compile
raise error, v # invalid expression
error: nothing to repeat
***
Changing the url conf so that both of the arguments are positional,
rather than one positional and one named, and then calling
reverse('entry', args=['johndoe','blogentry']), gets me the same
error.
What am I not understanding about url configuration and reverse()!!??
Thanks in advance,
Eric

Re: Looking for a security/encryption programmer for small contract
Hi, Thank you for all the information, it seems like you think it easy to do, as everyone accept to help me for free :-) The solution used before was to send to encrypted string in clear in a email. It used a perl impletation of the one-time pad. Emanuele, your said : As for safety, nothing is safer than OTP, but are we sure that your customer is able to go to great lengths to distribute long key streams over a perfectly safe channel to the sales representatives? Isn't the encrypted string secure? The method to send the string can't be secure. It is sent by email. The point is to encrypt it on the server, send it over an unsecure network. Then, when the sales rep. receive it, he will decrypt it. I tried tonight the gnupg. It works fine on my mac with thunderbird, but my client use outlook (gpg plugin is quite old), so I think I'll have to try with python-crypto. But pycrypto need to be compiled, I don't know if I can host it where I want. I'll check this out.

Image upload in user's directory
Hi, I am using the following in my Image model: file = models.ImageField(upload_to='/%y/%m/%d') I want every image to be uploaded in the users directory like '// %y/%m/%d' instead of all files in default location.

Complex relationship for user profile
Hi list! (first post) I've created a small application to suit a new project I am working on, however I have a question regarding using the user profile feature. I have the setup working properly according to the documentation and it works, what I need to know is if I can create a field in my user profile model that will mimic or update fields on the users table. For example, when I add a model for the profile, I would like to create a relationship so I can display and update the user's email on my admin page for the profile model, and not have to go to the users edit page to do so (and actually it would be handy for a couple fields...) Not sure how to pull this off, I'm only a couple days into Django (and loving it!)
