design. I was just curios...

It will very much vary on a per-host basis. Django code may not be responsible for serving all of the URLs for a particular site, for example. Somewhere in the web server's configuration (regardless of which web server is being used), there will be a setting that says "everything under this part of the URL tree gets passed off to that Django process over there for processing". Different parts of the URL tree may be passed off to different Django instances. So whether Django is responsible for serving a response to www.mysite.com/ depends on the configuration of your site.

No, you can't, and that's by design.
Django's template language is not intended to be a full programming
language. It's intended to be a simple mechanism for getting the logic
that has been determined in the view to be displayed. This is for two
reasons - firstly, to keep the template language simple so that
designers don't need to learn how to program, and secondly, to
reinforce good design: View logic should be separate from template
appearance.
If you have a need to pass arguments to functions in the template, you
are probably violating the second condition. You either need to put
this logic into your view (i.e., call the function with the arguments
in the view, and pass the result in as a context variable), or add a
method with no arguments that is a version of the function you want,
but with the arguments preset.

Deployed url mapping
On a deployed django site, what url does Django use when scanning urls.py when user browses to www.mysite.com ? When I access my (non-django) site with www.mysite.com my host serves up the file that i see as html/index.html If the polls tutorial is deployed to my host, does the mapping in urls.py work? urls.py has a line: (r'^polls/$', 'mysite.polls.views.index'), which i think means that "www.mysite.com/polls" will get the index page, but "www.mysite.com" will fail Shouldn't urls.py have something like (r'^index.html$' , 'mysite.polls.views.index' ), or perhaps: (r'^$' , 'mysite.polls.views.index' ), or perhaps (in my case) (r'^html/index.html$' , 'mysite.polls.views.index' ), or will this vary with my host?? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Don't forget, either, that you can use a get_title method with a property so it
looks like a title attribute, if you prefer. Aesthetically I prefer
{{house.title}} to {{ house.get_title }}.

You need to have specified null=True and blank=True on the ManyToManyField in your model (and you need to have done that before you created the database, otherwise it will not permit NULL values in that column).

That shouldn't work as initial is meant to set the value of a field.
I had the same problem and a peek at the source told me that a
ChoiceField has a 'choices' attribute which is settable so:
form = MyForm(...)
form.fields['publ'].choices = ((1,2),(2,3),(3,4))
will work, but I don't know whether it is the right thing to do (TM).

Re: ValueError: Empty module name
Ah-ha! I think I've found the issue. The problem was coming from the template context loader I was using. Or rather, how that was set in the settings.py file. I only had one template context loader set, and forgot to include a trailing comma so that it could be processed as a tuple instead of a string. Once I added that, everything works as it should. Just one of those little gotchas that you have to look out for.

by initial argument, you are meant to pass the initial VALUE (which
choice is currently selected), choices on the other hand are part of
the field's definition...
if you want to setup the choices dynamically, set it in the form's
__init__ (search the list for examples, there were quite a few)

passing parameters to a method from a template
I couldn't find any reference on passing parameters to a view method
from within a template. All I could find are some examples of passing
a single parameter to filter functions like:
{{ pub_date|date:"F j, Y" }}
Is there a way of doing this?

you can do

Re: Custom model initializers - getting logged in user in django models
This doesn't seem very clean to me...
I also need to have logged-in user available in my models, so I have
written a custom middleware that stores the user in thread_locals:
import threading
_thread_locals = threading.local()
def get_current_user():
return getattr( _thread_locals, 'user', None )
class RequestMiddleware( object ):
def process_request( self, request ):
_thread_locals.user = request.user
then, I can use get_current_user() anywhere in my application and it
will provide me with the current user, for some fields I even have
something like:
user = models.ForeignKey( User, default=get_current_user )
I cannot take credit for this, I found it on
http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser

Re: rendering dynamic fields in newforms
for rendering you should use BoundField...
I use something like this...
for s in :
name = 'stay_' + str( s.id )
bf = BoundField( self, self.fields[name], name )
output.append( u'%s' % bf )

Re: Django over modpython
Yes, most of the hostings have fastCGI, but not flup. I know the best is to have VPS hosting, but they are very expensive, and I think I can manage with a shared hosting.

Custom model initializers - getting logged in user in django models
hi,
i am creating a very simple board and wanted to add a method to my
models which would check if there are any new posts in a thread /
forum for a given user.. for this to work .. i obviously need the
currently logged in user in my models ..
but i didn't want to iterate through all my models in my view, since i
used the django.views.generic.list_detail.object_list which does the
paging and everything for me ..
so i thought the easiest way would be to allow adding of custom
initializers.. which would be called once a model was created by
django.db.models.query.QuerySet .. so i played around a little until
it worked for me: http://yourhell.com/~kahless/query_initializers_patch.diff
the usage is quite simple:
class MyModelInitializer(object):
def __init__(self, request):
self.request = request
def init_model(self, model):
model.do_init( self, self.request.user )
(my models would have a 'do_init' method which takes the user and
stores it internally)
the object_list would then get a queryset argument in my view like:
queryset =
Post.objects.filter( . ).add_initializer( MyModelInitializer( request ) )
and my templates could simply call {% if thread.hasNewPosts %} ...
so .. is this a clean solution ? or can this be done differently ?
and .. would there any chance this patch could find it's way into
django or does it break any main design philosophy ?
- i'm very new to python and django alike .. so there might be an
obvious other solution.
thanks & cu,
Herbert Poul

Reuse inclusion template tag in admin textarea?
Hi,
i'm using the following template tag in my application:
@register.inclusion_tag('gallery/flv.html')
def flv(movie, width=320, height=160):
"""
"""
fl = FlashMovie()
return {
'flv_player': fl.get_flvplayer(),
'movie': '%s/%s' % (fl.get_upload_url(), movie),
'width': int(width),
'height': int(height),
}
In the templates i simply write {% flv "foo.flv" 320 160 %} to get the
appropriate html for the movie.
Is it possible to reuse the inclusion tag in a admin textarea?
Say i write this into a admin textarea:
Here's my cool movie: {% flv "foo.flv" 320 160 %} ...
And in the model's save() method the template tag is replaced with the
appropriate piece of html (from gallery/flv.html), which is then saved in the
db. Can this be done, or should i better parse the content myself?
Best Regards.

Help about saving two linked instances...
Hello everyone!
I've approached Django and Python from a few time and i love them
both.
As i am newbie i have a noobish question. My problem is: i have to
store a Resource object splitted in two tables as following:
class Resource(models.Model):
title = models.CharField(maxlength=100)
creator = models.CharField(maxlength=50)
...blah blah
class Resource_systeminfo(models.Model):
resource_ID = models.ForeignKey(Resource)
owner = models.ForeignKey(User)
date_birth = models.DateField()
(that represent who added the resource in the db, and when)
All the info in the Resource table are filled in by a user. As a user
insert a new resource, i wish to create in automatic a
Resource_systeminfo instance linked to the first, but i have no idea
about how to do that...
Actually my view is
@login_required
def resource_edit_insert(request, id=None):
ResourceForm = form_for_model(Resource)
if id is not None:
pass
#...i still have to implement resource modification :)
else:
if request.POST:
form = ResourceForm(request.POST)
if form.is_valid():
form.save()
'''Here starts my problem. I tried to use a form_for_model (great
tool) but obviously i have also to insert the foreign key to the
Resource object... and i absolutely dunno how to do it!'''
ResourceSystemForm =
form_for_model(Resource_systeminfo)
data = {'owner': request.user, 'date_birth':
datetime.date.today()}
systemform = ResourceSystemForm(data)
systemform.save()
return HttpResponseRedirect('/mainpage/')
else:
context = {'form': form, 'error_message': "Please
correct errors below."}
else:
context = {'form': ResourceForm()}
return render_to_response(
'catalog/resource_edit_insert.html',
context,
context_instance=RequestContext(request)
)
If someone knows how it could be done... A note: I would prefer not to
join the two tables, keep it as very last solution!
Cheers and sorry for my terrible english.
