I wonder if the template system has become a bit more complex since then. I also wonder if whatever tests they used included things like includes in for loops. I tend to think that the filesystem is slow and anything to remove FS calls and shove things in memory is a good thing -- especially something that could potentially be in a for loop. Obviously there are trade-offs as you mention but the patch didn't look that complex to me -- actually it was surprisingly straight forward. I've considered applying this patch and testing against a project I'm working on. Maybe that would help prove to either Django or me that this is or isn't worth it.

Django for a seminar registration app?
Dear Django experts, I am a python programmer with about 1.5 years part-time python experience and some web site building experience. I am about to take a project of building a seminar registration site for a client. I have already decided I want to handle that project in python, but I have a hard time deciding which framework to use. Django, Pylons and Turbogears all seem reasonable candidates. I like Django for its active community and development and the somewhat more coherent framework (it seems to me), Turbogears for its widgets, and about Pylons I havent't read/dabbed enough yet. I heard that most things work great out of the box with Django, but beware if they dont! Also, Django seems to be geared more towards publishing by one or a few users, while my task will be more about many users managing their own resources. (see below) With Turbogears I haven't gotten many examples work out right away, and with neither I have been able to quickly have a authorized-access based web site up. I haven't tried for more than 1-2 hour per framework though. Pylons I havent really tried enough (and was a little discouraged to hear it might get overridden a lot with the merge into TG). I am now looking for help in choosing a framework and estimating the effort it takes to build the app. The project will have to be done in under 3 weeks, so I can't really afford to run into dead ends and restart with a different framework. :-/ The main functions of project will be: - let users register (with or without email verification) ONLY AFTER registration - let users select from a list of seminar dates - register for a seminar (probably only 1 per user) - unregister from seminars until seimnar_start_date-X days - manage their data - get an e-mail X days before the seminar (probably cron job) have an admin (the seminar speaker) be able to - CRUD seminar dates - generate participant lists - print invoices There will be some restraints like minimum number of participants for a seminar for it to take place, probably batches of seminars (2 or 3 per day) that will get canceled if one of the gets canceled. I think that should be relatively painless with some python functionality. The main questions I have right now are: Do you think Django could handle the task easily or do you think something else would be better? What do you think will be the hardest part to implement? And how many hours/days/weeks would you think it takes a new user like me to get the thing up? Ideally I would have a showcase demo with limited functionality up in 6 or 7 days (of which I can spend maybe 4 hours each day on it). Do you think that s possible? Very much looking forward to any hints, pointers and comments, Nico Richter (P.S. I will post this to the Django, Pylons and Turbogears groups, so please forgive me if you get this more than once.

Are you trying to assign all new docs to an existing Category object
then? I think if you used the 'initial' argument in in the form
constructor it would work. Something like:
initial_data={'categories': [category.id]}
form = DocumentForm(request.POST, initial=initial_data, instance=new_doc)

How to initialize M2M field in new ModelForm?
I need to initialize a selection in a M2M field of the Document
ModelForm during the first GET of a form that creates a new Document -
classes and view as follows:
class DocumentForm(forms.ModelForm):
class Meta:
model = Document
class Document(models.Model):
...
categories = models.ManyToManyField(Category)
view function:
def create(request, category_name, template='edit2.html', params={}):
category = get_object_or_404(Category, name=category_name)
new_doc = Document(author=request.user, pub_date=datetime.now())
if request.method == 'POST':
form = DocumentForm(request.POST, instance=new_doc)
if form.is_valid():
.
else:
form = DocumentForm(instance=new_doc) # todo: figure out how
to initialize categories
params['form'] = form
return render_to_response(template, params,
RequestContext(request))
I've tried a few approaches without success.

You need to set your ADMIN_MEDIA_PREFIX (http://www.djangoproject.com/documentation/settings/#admin-media-prefix) appropriately, as well as make sure it doesn't collide with your own MEDIA_URL.

I got a similar message when I try to change users with
django.contrib.auth and again only on the server.
Create or change objects without the admin works fine. So I think its
a problem with the admin. But I don't know why I only have these bug
on the server and not local.
The error message is in these case:

Ohh, i see that there is another different between server and my local

computer
Hope you can help me

But myapp/login.html expects a number of extra objects from that
populated by the login view. In other generic views, I could have
added extra objects by using extra_context optional method. But this
view does not take the extra_context optional argument., so how can I
pass extra objects to the template?

Re: Extending pythonpath within python code
Thanks for the tip!
However, it's a bit strange because it only accepts paths with double
back slashes, instead of the forward slashes required for declaring
the template path for example.
import sys
sys.path.append('E:\\workspace\\myproject\\trunk\\apps')
works
but:
import sys
sys.path.append('E:/workspace/myproject/trunk/apps')
doesn't work
Is there a way around that? As I'm storing the absolute path of my
project in a constant variable (with forward slashes), I'd like to do
something like this:
ABSOLUTE_PROJECT_PATH = 'E:/workspace/myproject/trunk/
sys.append(ABSOLUTE_PROJECT_PATH + 'apps/')
TEMPLATE_DIRS = (
ABSOLUTE_PROJECT_PATH + 'templates/',
)
PS: As you may have guessed, I'm running under Windows.

We are/will be using one squid per webserver that caches static content (including javascript, css and user supplied files). Expiration Date is set to several years and whenever something changes we just increase the version number of the file [1]. Users cannot change their files they have to reupload it so it gets a new id and a new filename. Theoretically you wouldn't even need a squid for static content like that cause the content should be cached in the browsers cache but you don't want users that use a very small cache to hit the application servers all the time. The actual pages are cached within django cause at least a small fraction of each page is always generated dynamically. Works like a charm, althought I haven't looked at varnish yet, perhaps I should.

This line will be executed once (exactly once and only once) when the feeds.py file is imported. Which means it isn't really very dynamic. That's why you're seeing the error in urls.py, as well: you no doubt import feeds in blogango/urls.py and that causes the class to be parsed, which executes lines like this. > title = blog.title > link = "/rss/latest/" > description = blog.tag_line Title and description can both be methods, so the more robust way to write what you're trying to do is something like: def title(self): try: b = Blog.objects.all()[0] except IndexError: return "something for the empty case" return b.title and similar for description. Maybe factor out the bit that gets the Blog object and even store it in an attribute after the first time to avoid repeated lookups. The general thing about the syndication framework is that most of these attributes can either be a straight constant value (title = "foo"), a method that takes only "self" (def title(self):...) or a method that takes self and the current object (def title(self, obj): ...). Have a read of http://www.djangoproject.com/documentation/syndication_feeds/#feed-class-reference to see the possibilities. Regards, Malcolm -- Telepath required.

Firstly, ModelForms *is* part of newforms. It uses standard newforms practices. Calling is_valid() on a form class returns False if and only if you've either forgotten to supply data or self.errors is not empty. So is_valid() is intimately tied to self.errors. > Anyway, I changed > the code like this: > > def addph(request): > if request.POST: > newpage =Ph(request.POST) Here's the problem.. I should have spotted it the first time. You need to pass in any files as the second argument to the form. newpage = Ph(request.POST, request.FILES) So the form is complaining about something valid: you weren't giving it the file data. I think you'll find that everything should work once you change this.

checked that - am getting an error list - 'photo' 'this field is
required'. Which silly because the field is filled in. I tried
ModelForms with other field types, and find the same error comes when
a required field is not filled in. Even running is_valid is of no
help, because, unlike in new forms, a negative value for is_valid
does not return the form with errors as it should. Anyway, I changed
the code like this:
def addph(request):
if request.POST:
newpage =Ph(request.POST)
if newpage.is_valid():
f=newpage.save()
return HttpResponseRedirect('/web/showarticle/3/' )
else:
form = newpage
else:
form = Ph()
t = loader.get_template('web/addbrick.html')
c = Context(
{
'request':request,
'form': form,
})
return HttpResponse(t.render(c))
I now get a big red field required error message next to the
imageupload widget, and the said widget is empty - in other words, my
file did not go to request.POST. So it must be in request.FILES?

Re: Tutorial 2 admin Template not found
I have no problems going through the tutorial (and creating my own apps) on my mac. Are you using the development server to do all of this? I could see where you'd have the problems you are having if you are trying this all through apache/mod_python. How did you install django? from source? I don't know if there is a darwinports or a fink package out there. The way I installed django on my mac (running leopard) was like this: cd /Library/Python/2.5/site-packages sudo |svn co http://code.djangoproject.com/svn/django/trunk/django django I never had to do anything like manually configure the admin TEMPLATE_DIRS. I am using the development version, and I haven't been around long enough to know for sure, but you may be experiencing a bug related to django-0.96/mac. You do need to map a URL for the admin media url in a production server--like apache. On my production server, I haven't bothered to get it working, so my admin interface is very boring and plain looking, but I don't really use it anyway. On the django built-in development server it should just work. Good Luck!

Re: Tutorial 2 admin Template not found
So I've discovered that I can get the admin page to show up if I add '/ System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ site-packages/django/contrib/admin/templates' to TEMPLATE_DIRS in the settings.py file for my project (for some reason this doesn't work in global_settings.py).

The python path lives in sys.path (which is a simple list). This means
that you can add new directories with sys.path.insert(0, 'your/path') or
sys.path.append('your/path'), whichever you like.
I do this all the time, mainly in the FastCGI caller script, but also in
settings.py to enable access to middleware classes and templatetags
which I use in nearly every project.

Extending pythonpath within python code
Hi there, To keep my projects tidy, I'm used to having all my apps in a subfolder "apps". This means that I need to add that subfolder to the pythonpath. I can do this in apache or by doing runserver --pythonpath=apps. However, I'd like to extend the pythonpath within the code, for example in settings.py(*). That would save me from altering apache config files and would therefore make deployment a little easier. Is that possible, and is it recommended practice? Cheers!

Re: Getting Error - "Error while importing URLconf 'blogango.urls': list index out of range"
Ok I found the error, but I still cant understand why this is
happening. What I did was that, in the blogango.urls, I have a line
like
import feeds
THe feeds.py is,
class main_feed (Feed):
blog = Blog.objects.all()[0]
title = blog.title
link = "/rss/latest/"
description = blog.tag_line
def items (self):
entries = BlogEntry.objects.all()[:10]
return entries
If I navigate to any page after I have just run manage.py reset ...,
there is no Blog object and Blog.objects.all()[0] raises exception. If
I change feeds.py to something like,
class main_feed (Feed):
try:
blog = Blog.objects.all()[0]
except:
class DummyBlog:
def __init__ (self):
self.title = ''
self.tag_line = ''
blog = DummyBlog()
title = blog.title
link = "/rss/latest/"
description = blog.tag_line
def items (self):
entries = BlogEntry.objects.all()[:10]
return entries
I get no error. What I do not understand is why should the main_feed
class be instantiated as soon as I import feeds? Should not the
instantiation happen only when the feed is accesed?
