Re: Creating a "wizard"
have a look at ticket
http://code.djangoproject.com/ticket/3218
it contains a proposed wizard class for newforms - simply subclass it,
override the done() method and then instantiate it with a list of
newform classes...
if you need more functionality (dynamic forms etc.) you will have to
override more methods (process_step() )
if you have any questions/feature requests please ask away I am
desperate for some feedback... ;)

Re: order_by with Foreign Keys
Hi Carole,
There is a workaround for this problem. I am using the latest
subversion build of django, so I don't know if it works with the last
official build or not.
Here is an example:
ProductVersion.objects.select_related().order_by("kindledb_product.name","version_number")
Here are the model definitions:
class ProductVersion(models.Model):
product=models.ForeignKey(Product)
version_number=models.CharField(maxlength=16)
availability_date=models.DateField(null=True,blank=True)
release_notes=models.TextField(blank=True)
class Product(models.Model):
name=models.CharField(maxlength=128)
Note that kindledb_product is the name of the database table that
stores the information from the Product.

Generic views and filtering
Hello,
I have a few question with generic views as I can't manage to have all posts
related to a tag or category
My model is :
class Post(models.Model):
author = models.ForeignKey(User)
title = models.CharField(maxlength=50)
summary = models.TextField(blank=True)
message = models.TextField()
category = models.ManyToManyField(Category)
tag = models.ManyToManyField(Tag, blank=True)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
pub_date = models.DateTimeField('Date de publication',
auto_now_add=True)
pub_status = models.BooleanField('Publie ?', default=True)
url = models.SlugField(prepopulate_from=("title",))
class Tag(models.Model):
name = models.CharField(maxlength=50)
description = models.TextField(blank=True)
url = models.SlugField(prepopulate_from=("name",))
I try to play around with something similar to this in urls.py :
(r'^tag/(?P[-\w]+)/$', 'object_list', dict(queryset=
Post.objects.filter(tag='slug_field'), slug_field= 'url', )),
but did not manage to get anything except errors.
Idea is that all url with /tag/foo gives all posts that have the "foo" tag.
What would be the correct solution ? Do I have to do as James [1] suggests,
ie to filter it in views.py with some generic views methodes ?
So far I run .95 but can move to svn if it is worth :-)
Regards,
Nicolas

Re: Removing SQL From Templates
> I like having access to the models attributes, such as > get_absolute_url, we use things like this quite a bit in our templates You could relatively painlessly 'flatten' the attributes of the model instances in place before rendering template, i.e. spam.get_absolute_url = spam.get_absolute_url() Or programatically for attr, val in spam.__dict__ : if type(val).__name__ == 'function' : setattr( spam, attr, val() ) Clearly, related object members would have to be handled slightly differently, and to save expense on SQL queries you might only want to evaluate some subset of the object's attributes while deleting others. But it seems to me that at some point you must specify precisely which object members will be available to the template, and you might as well generate a restricted version of the object when doing so.

Re: Creating a "wizard"
Howdy Bram,
Here is an example of something that I am doing with newforms and
sessions and it seems to work very well. In my case I have a search
form displayed. Depending upon the options that are selected by the
user, when they submit the form it will be handled by one of several
different view methods. But they all need access to the information in
the form so I save it in the session first when the search form is
submitted.
First, here is the view that displays the form:
@login_required
def search(request):
"""
Serve the main search screen
"""
if request.method == "POST":
edit_form = SearchForm(request.POST)
if edit_form.is_valid():
for k in edit_form.fields:
if k in request.session: del request.session[k]
for k in edit_form.data:
request.session[k] = edit_form[k].data
return HttpResponseRedirect( "/kindledb/search/%s/" %
request.POST['search_type'] )
else:
edit_form = SearchForm()
return render_to_response("kindledb/search.html",
{'edit_form': edit_form})
Note that when the form is submitted, the first thing it does is clear
out any session data from the last time this search page was called up.
If you don't do that you can end up with stuff hanging around from
previous searches.
Then it stores all of the information from the newform instance into
the request.session. Then it redirects to the appropriate next view.
In that next view, it has access to all of the information that was
saved in the session. This works out really well because they are all
paginated generic object_lists. So the user can navigate through the
resulting information no problem.
In your case, you could keep shoving stuff in the request.session if
you had several pages of forms that they user had to go through.

Django's FastCGI init.d script for Linux
Hi,
For my convenience I've written an init.d script that automatizes the
startup of my FastCGI django servers. As it might interest other
people, I share it here. Feedback is welcomed.
I can put as many sites as I want, and it will automatically assign
different port numbers to different servers in an increasing order
starting from $PORT_START. It follows the start stop restart
force-reload syntax of the startup scripts and integrates with the
startup process in Ubuntu and Debian systems. Should work in RedHat as
well, not in Gentoo though.
http://www.guindilla.eu/blog/2007/01/12/djangos-fastcgi-initd-script-linux/

extending user model, but keep getting type error for user.id
I'm using the 'one to one' method of creating a user profile which extends django's built-in user model. This is a workaround suggested by James Bennett on his b-list blog, and I think several other people are using this or something similar. My problem is that I have a database I am importing. It contains user info which I need to insert into both the built-in user, and my userProfile models. This is how I am attacking it right now: 1- add new user, where 'u' is an object read from the old data: newuser = User.objects.create_user(u.uname, u.email, u.pword) 2- add the extra user info to the userProfile model using the "last inserted id" newprofile = UserProfile( user = newuser.id, office = u.office, ) Unfortunately, I get an error calling "Invalid Value", but aren't they both IDs of the same type? This is what it says: Invalid value: 'user' should be a instance, not a Seems like this should work, and I've seen examples using a similar approach, but this has stumped me for a few weeks now and I'm getting tired of looking at it. :-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Creating a "wizard"
Bram, If I recall, there have been some discussions about building this sort of capability in new forms. However, you can see how I've done something similar in Satchmo using the old forms implementation. It's not automatic, but it does allow someone to move through all three steps and the final order is not completed until the user confirms. http://satchmo.python-hosting.com/browser/trunk/satchmo/shop/views/ Look at the views checkout-step1 through step3 to get an idea of one implementation for a similar sort of checkout process. -Chris --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Can a view open a page in a new browser window?
Thanks Julio and Jeremy. When the users generate multiple reports I go to a page that shows links to the reports and let them click the link for the report they want to see. However, when there is only one HTML report to view it would be one less click for the user if I could bypass that page and go right to the report. Guess I'll show them the report results page anyway, since it's just a small refinement anyway. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Uploading large files via http FORM

sqlite3, QuerySet.extra() and order_by() inconsistencies between Python versions
Hi -
Has anyone else observed differences between the behavior of order_by
between Python 2.3 and 2.4? Under 2.3, the following code drops many
items in thread_list when using order_by():
...
extra_last_updated = """
SELECT date FROM forum_post
WHERE forum_post.thread_id = forum_thread.id
ORDER BY date DESC LIMIT 1
"""
thread_list = thread_list.extra(
select = {
# ...
#'last_updated': extra_last_updated, # bug:
http://code.djangoproject.com/ticket/2210
'date': extra_last_updated,
'last_poster': extra_last_poster,
#},)
},).order_by('-csticky', '-date')
The above works as expected in a mod_python setup with Python 2.4 but
not Python 2.3 (Debian Sarge vs. Etch). The pysqlite versions I'm
using are identical in both setups. Of course, I haven't controlled
for a lot of other factors, but maybe someone has observed this before?

Re: close database connection ?
I installed Django-0.95, that shouldn't be the problem. after i get data from the database first there are some actions in python but the DB is called afterwards.

Creating a "wizard"
Hi all, I started working with Django some time ago, and i've to say that I like the framework so far. However, now I would like to create a kind of wizard for an ordering system. In short, a process with back/next/cancel buttons. It would be nice to save everything in the session or some other temporary place and create an order when all steps are finished. Furthermore, the steps could be somewhat dynamic, the step after a form that prompts the user if he/she is already an existing customer could be a form for customer registration, or a login page. Any ideas how I could get this going? Tia, Bram --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Newforms 'preferred practice'
Hello all, I've been playing around with the newforms library and I'd like to check that I'm on the right track. I've got a fairly complicated model that has a few foreign keys and m2m fields. One of the m2m fields references a table with ~130,000 rows so the usual select boxes aren't that usable. I've created a form which simplifies the entry but I would like to check the preferred way of doing certain things. 1. Additional validation - One field is a RegexField but I would like to add extra validation. At the moment I've subclassed it and added my own 'clean' method. 2. Saving the model - I've implemented a save method in the form which will return an instance of the model in a similar fashion to form_for_model. Is this good practice or should I create the instance in my view and populate it from the form? 3. Binding data - I'd like the form to handle editing of an instance. I could construct a dictionary of values and pass it to the form as per the docs but I'd like to just pass a model instance and have the form sort things out. Is this advisable? If so then does anyone have any pointers about what methods I need to implement? Thanks in advance for any pointers. Felix P.S. Are there any thoughts about form inheritance? I'd like to be able to create a form base on another but with some more fields.

Re: Django Projects and Subversion
I am just finishing a Django project that is managed by Subversion. I have set up 3 web sites to manage it - a "development", "staging" and "production" server. This is a common paradigm, nothing that I came up with myself. You can have active committing by developers to the repository and there are no problems. Just check out a particular revision onto the the staging server and test that everything works as expected. When you are confident that everything is OK (for that revision), you can check out the same revision on the production server (effectively performing an "upgrade"). Each web server requires a slightly different settings.py file since you want each to use their own databases, but most of the content of these files will be the same. I even use Subversion to manage these 3 settings files in the same repository. I have 3 settings files: settings_development.py settings_staging.py settings_production.py When updating one of the servers with a particular revision, all of these files are downloaded to the particular server you are dealing with. To use the appropriate settings file, I create a symbolic link: settings.py that points the the appropriate settings file. You can get by without introducing this link by referencing the appropriate settings file in each Apache Virtual Server configuration, but if you want Django's "manage.py" script to work transparently, you need this link. The important thing is to *NOT* put this link under revision control, i.e., it is not managed by the Subversion repository. It will stick around while the other files in the directory are being managed by Subversion.

There are no specific plans that I am aware of (i.e., no schedule that says 'will be fixed by 25 Jan'). There was talk of a refactoring of query.py that was to address problems like this one, but the developer that was championing this cause (Malcolm) has been absent of late. Obviously, it is a bug, and it would be nice if Django had no bugs, but the core developers have limited time, and we spend it where we think it has the most benefit. If someone were to step up and fix this problem, it would probably find its way into the trunk fairly quickly (assuming it was a complete patch, of good quality, with unit tests, etc).
