Thanks! I can't blame you, Django's template language is not particularly elegant or convenient to extend. I'm not using it currently. However, a cursory look at the source code doesn't reveal anything like this handling of layouts. If you do want something different than Django's template language, I'd suggest that you get a look at Mako (which is a general-purpose Python template language). You need to be aware, though, that if you choose a different template language, this will mean that you will have to call a different render_to_response/render_to_string. Which means, in particular, that if you want to use a third-party application which has its own views, you'll probably end up having to rewrite the views so that it can find your layout, for instance. Same for apps with their own tag library (like django-compress). Cheers, Emm --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

amCharts and Django
Anybody using amCharts with Django? I'd like to be able to hook the chart directly up to my model. I found this ( http://aaron.oirt.rutgers.edu/myapp/amcharts/doc) about using amCharts with WHIFF, and it seems like building the descriptor would be straight-forward, but then I'm clueless about the WHIFF/Django interaction.

GHRML Documentation
I'm trying to learn how to work with django after working with ruby on rails for some time (not too long). Rails has a nice template language called Haml (http://haml.hamptoncatlin.com/), which I find much more readable than regular HTML. It is also indent oriented, which all python fans must find appealing (myself included). I found a similar template language called GHRML (http:// www.ghrml.org) for django, but the documentation on it is very scarce. It's also very young (currently in v0.11), and I'm not sure if it's even being actively developed anymore. I'm trying to find out if it supports basic template stuff like "extends" and conditionals, so if anyone who's using it could point me to some good docs on it, assuming those exist, that'll be great.

openid
So after looking around a bit it looks like simonwilsons openid package is pretty where it's at for openid in django. Question is: is the package that hasn't been touched 2 years django_openidconsumer the right one to use or has django_openid come along far enough to implement/test. I note that there was an email further back that said django_openidconsumer doesn't work unless you use the openid2.0 branch so I'm a bit lost.

Re: Is Django easy to learn and use for my web project?
I've only been using django for a few weeks. I had NO prior Python experience. I've been cracking a couple of hours a day on a site that aggregates RSS feeds and I've already got it working nicely. I've played with PHP and Rails before, and django feels to me like it's the easiest to use. I'm amazed at how little code I have compared to the functionality of my site. It so far seems to me that maintainablity should be eased by the way an app is organized by django. I followed along with www.djangobook.com and then googled or hit this group up for anything I wanted to know more about.

How long it takes to finish the project? 2 weeks to a month to get a site going with basic functionality - the rest of your life to make it perfect ;-). You do not really need to use javascript, at least at the outset. The key thing is to go into production as fast as possible and then keep adding modules. Start with the blog and the forum - there are ready made ones which you can plug in and modify, but to practise it is better to roll your own. For the blog you just need a couple of models and you can add django.contrib.comments for the comments part.

However, those libraries do share a common problem: the S3 upload happens within the request-response cycle. That might be okay for small files but if you need to handle the big ones you'll have to use a different approach: save the files to a temp folder, and have a daemon running as a separate process to upload them to S3. Files may not be immediately made available, but that's ok for a lot of applications, and it makes the request-response cycle faster and more scalable, considering you wouldn't be keeping so many threads around at once. I've just completed a full blown solution for this, including the daemons (and separate worker daemons to perform special operations on uploaded files, like video transcoding). I can't release the source, but if you'd like I could probably send you a few snippets privately. --Jonas Galvez --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

model inheritance and admin labeling
I am trying to create an abstract base class for a hierarchy. One of the fields in the base class is child_nodes, refering to 'self'. In the sub-class I cannot seem to find a way to control the labeling of the field in the admin. No matter what I do it comes up as 'Child nodes'. I want to change it to something that is related to whatever the name of the sub-class is, be it 'Group' or 'Category' or whatever. Ideally in the case of 'Group' the label would be 'Sub-Group' and so on.

database backends timing out
I'm having an interesting problem. After inserting a bunch of records into my database ( about 400,000), it the database starts refusing connections. Even after restarting the database daemon, I can not query the database (django lets me query, but returns nothing in the querysets). The only method that works is dropping the tables and then I can attempt the import again. This happens with both mysql and pyscopg2-postgres backends. This is this error I get in my postgres logs: LOG: 08P01: unexpected EOF on client connection LOCATION: SocketBackend, postgres.c:323 DEBUG: 0: proc_exit(0) LOCATION: proc_exit, ipc.c:98 DEBUG: 0: shmem_exit(0) LOCATION: shmem_exit, ipc.c:164 DEBUG: 25001: SET TRANSACTION ISOLATION LEVEL must be called before any query I am using some rawsql to do an executemany, and I'm handling the transaction commits manually, but even when taken that code out and just using standard *.objects.create, and the results are still the same. The fact that it happens on 2 different database backends leads me to believe that it is a problem with the django database layer. This occurs with both the django stable version, and trunk.

filtering between two different tables
Hi, I am pretty new to django and python as well. I am working on my first django project and trying to find the best approch to solve the following issue : On my project I do have a voting system. the votes are for a specific item. Each user can vote once per item. What I am trying to do is that a user can see all of the items he can vote excluding the ones he already voted on. here are the models for an example : class Item(models.Model) : user_owner = models.ForeignKey(UserProfile) item_notes = models.CharField(max_length=500); added = models.DateField() class Vote(models.Model) : item= models.ForeignKey(item) user = models.ForeignKey(UserProfile) notes = models.CharField(max_length=500); score = models.IntegerField() added = models.DateField(); The first filtering I am doing is to take away any items that are owned by the specific user. So I am doing the following : items = item.objects.exclude(user_owner = profile) On those items I now want to retrieve only the items that were not voted yet by the specific user. My problem here is that I cant use the objects.exclude because I want a specific entry on the item tabe to be compared with all the votes realted to the user. Any django way to do this ? or should I just use a for loop here ?

Unlike a lot of similar posts on the message board (I have searched), I have MySQLdb installed. The lines in question are just 'import MySQLdb as Database' and the associated try/catch throwing the error. When I run python from a command line and type 'import MySQLdb' it imports just fine. I added to to the root's .bash_profile and the .bashrc of the 'mysql' user. The file definitely exists (in /usr/local/mysql/lib) I used the variable LD_LIBRARY_PATH in the two profiles to make the 'import MySQLdb' statement work, is that the correct environment variable?

can you have a flatpage with url of "/" when Debug=True?
If Debug = True, you can have a flatpage with URL = "/" that is handled by FlatpageFallbackMiddleware: MIDDLEWARE_CLASSES = ( ... 'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware', ) If Debug = False, the flatpage will 404. Is there a way to have a flatpage as your site's index/home page, and have debugging turned off? -joe --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Is it bad to rely on db exceptions?
get_or_create() is probably perfect, I just haven't come across it in the djangobook yet. I'm a newb. Gonna have to start combing the docs a little more thoroughly! Thanks for the suggestion!

Re: Debugging methodology suggestion on PIL file upload problems
Finally getting back into the swing of things in studying django.
I discovered 'Werkzeug debugger' and found out I was doing many things wrong
(saving to wrong place, trying to open the Image prior to saving it locally,
etc.).
Great debugging tool (wish I had an IDE, but this is better than printing to
files for debugging info, etc.).
Any other great debugging tool you guys have used?

I quite like Python as a dynamically typed language, more so than Ruby, PHP, JS, ... anyway, and I like the design & direction of django (the lack of magick compared to Rails which I tried before, the ideas of most batteries being included and working well together compared to e.g. Pylons, and the idea of pluggable apps which is a better modularity approach than pretty much everything else I've seen in the class, though I probably missed good ideas in other frameworks). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Why django? Framework design or language
Hi all, I know that this questions rise up often in this list, but I have a different side of view about the reason to choose django. I was wondering whether most people here choose django because of: a) the language itself and they already master python, so they choose django b) the design and the feature of the framework itself that fits their needs Okay, as for me, I chose django because of the design of the framework itself and the feature django offer. I'm not really a python programmer and was not a python programmer back then. So what about you?

the most obvious reason why this is bad is: it will stop working when you switch to an other database backend. but aside from that: what are you trying to archive? looks a lot like what the get_or_create() shortcut does...

TemplateDoesNotExist: 500.html during deployment
Hello! I managed to deploy my django project in production except static media. When I try to access http://localhost/adminmedia/account.js (my static media file), I get colorful page with stack trace of django.template.TemplateDoesNotExist exception and TemplateDoesNotExist: 500.html in apache2 log. My project root is /var/www/webapps/katrin-web. I want to have /var/www/webapps/katrin-web/katrin/adminmedia located in /adminmedia. It seems that Django tries to serve static media instead of apache2. What's wrong with my static media? Why standart 500.html doesn't display? Here is my apache2 conf: NameVirtualHost localhost:80 ServerAdmin postmas...@localhost DocumentRoot "/var/www/webapps/katrin-web" ServerName localhost ErrorLog "/var/log/httpd2/katrin-error.log" LogLevel debug CustomLog /var/log/httpd2/katrin-access.log common Alias /media/ /usr/lib/python2.5/site-packages/django/contrib/ admin/media/ Alias /adminmedia /var/www/webapps/katrin-web/katrin/ adminmedia SetHandler None RewriteBase / Options +ExecCGI AddHandler fcgid-script .fcgi RewriteEngine On RewriteRule ^(dispatch\.fcgi/.*)$ - [L] RewriteRule ^(.*)$ dispatch.fcgi/$1 [L] # some settings: PROJECT_PATH = os.path.abspath(os.path.dirname(__file__)) MEDIA_ROOT = os.path.join(PROJECT_PATH, 'media') MEDIA_URL = '/adminmedia' ADMIN_MEDIA_PREFIX = '/media/' STATIC_DOC_ROOT = '/adminmedia' --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

View arguments via url are not being passed to the view.
Hi group,
I am having a problem getting text in the url to be passed as
arguments to my view.
My defined urls are:
(r'^notes/', 'notes'),
(r'^notes/(?Pa|e|d{1})/(?P[0-9]*)/$', 'notes'),
My view is as follows:
@login_required()
def notes(request, action=None, id=0):
if action == 'a':
n = Notes()
n.note = request.POST["note"]
n.user = request.user
n.save()
elif action == 'e':
pass
elif action == 'd':
pass
notes_list = Notes.objects.filter(user=request.user)
return render_to_response("pim/notes.html", { "notes" :
notes_list, "action" : action, "id" : id})
When I navigate to domain/app/notes the template is displayed and I
have the action and id being printed to the page as 'None', and '0'.
When the page gets posted to domain/app/notes/a/0/ I get the same
exact information back and if action == a is never executed.
I have read through the docs over and over and it looks like I'm doing
it correctly but I guess I'm not. Does anyone have an idea what I'm
doing wrong?

You don't need generic relations here, just add a related_product
ManyToMany field do the Blog model in exactly the same way as you did
for the Article model.
