Automatic {% load %} ?

[Christophe Pettus]

In my templates, I'm making reasonably heavy use of custom tags.  Is  
there a way to avoid having to have the template authors put the {%  
load %} tags at the top of each template, since pretty much every  
single template is going to need to load the same set?

Re: decoupled url confs- can't reach admin page now

[Ross]

I'm struggling to find where the error is in my urlconf. When that
line I referenced previously is uncommented, I am able to get to the
other pages for which I have made views (which is just the home page
at the moment), but I can't access the admin. Could the problem be
that I have not written views for everything that the urlconf
references? Because I'm struggling to find an error in any of my
syntax in the urlconfs.

Admin requires your entire URLConf be valid.  Fix the error noted in the
exception, and admin will work again.  The reason why Admin requires a fully
valid URLConf is because it generates links on its pages using reverse URL
mapping using the url template tag or the reverse utility function (
http://docs.djangoproject.com/en/dev/topics/http/urls/#reverse).  That
process iterates through the entire URLConf and any errors found will cause
it to fail.

Well... if you want a single form, define a single form:

class MyForm(Form):
phone = fields.CharField(max_length=8)
email = fields.CharField(max_length=50)
name = fields.CharField(max_length=50)
...

If you want to automatically generate a single form, you're out of
luck. A ModelForm operates on a single model class. You can't build a
model class for two models.

However, this isn't a major problem. There's no requirement that you
use a single form in a view. You can easily use multiple forms in a
single view - for example:

def edit_client(request, pk):
client = get_object_or_404(Client, pk=pk)
if request.method == "POST":
contact_form = ContactForm(instance=client.contact, data=request.POST)
client_form =ClientForm(instance=client, data=request.POST)
if client_form.is_valid() and contact_form.is_valid():
client_form.save()
contact_form.save()
return HttpResponseRedirect(...)
else:
contact_form = ContactForm(instance=client.contact)
client_form =ClientForm(instance=client)
return render_to_response(...)

Re: Run a filter on path in {% extends %} tag?

Hello,
 Just use RequestContext + context processor, which adds theme based
context.
Just use vars like base_template (which could be set to skin_basic_base.html
by context processor). Hope you got the idea.

Run a filter on path in {% extends %} tag?

[ringemup]

I'd like my templates to extend different templates depending on the
skin the user has selected.The trouble is that the {% extends %}
tag has to appear in the template file before any custom filters are
loaded, so I can't run something like

{% extends 'wrapper.html'|select_theme:user_theme %}.

I know this can be done by selecting the template to extend in the
view and passing that as a variable to {% extends %}, but when I'm
nesting templates a couple of levels deep, it's kind of obnoxious for
my views to have to know about what other templates my templates are
calling.

Any recommendations?

Thanks!

Re: Is it possible to use custom template tag inside another tag?

[AmanKow]

> into variable and send this variable to template?

The usual way to go about this would be to modify your tag to take an
optional "as var_name".  When the tag has the optional portion, you
would update the value into the variable.  This way, behavior does not
change where you're using the returned value, and when you need the
value for further processing, you put it into a name of your choice in
the context.  The tag documentation has plenty of information about
writing tags which access the context:

decoupled url confs- can't reach admin page now

[Ross]

I was going through the tutorial and following directions (I think)
when it instructed me to decouple the url confs near the end of part 3
of the Django Tutorial. After I did this, I was no longer able to
reach the admin page. Now, whenever I try to reach the admin, I get
this error message:

TemplateSyntaxError at /admin/

Caught an exception while rendering: Tried vote in module
mysite.player_info.views. Error was: 'module' object has no attribute
'vote'

which is weird since I am typing http://127.0.0.1:8000/admin/ as the
url and this has nothing to do with the line:

(r'^(?P\d+)/vote/$', 'vote'),

in the urlconf.

What might have happened?

trying to do ip based resolve

[Kurt]

I think I must be doing something fundamentally wrong since this seems
like an easy problem...

I'm building a site, I want all ips not in INTERNAL_IPS to get an
"under construction" page and my internal ips to get the real site.
What I'm trying to do is call the application urlconf via the resolve
function.

The redirect to the construction page works fine.

The resolve seems to work since the /admin/ pages work but
django_authopenid do not, I get strange errors like "Reverse for
'user_sendpw' with arguments '()' and keyword arguments '{}' not
found."

If I change settings.py:ROOT_URLCONF to be "myapp.urls" then
authopenid works.

settings.py:
ROOT_URLCONF = 'redirector.urls'

redirector/urls.py:
urlpatterns = patterns('',
(r'^', 'redirector.views.redirect' ),
)

redirector/views.py:
def redirect(request, *args, **kwargs):
remote_addr = request.META['REMOTE_ADDR']
is_internal = remote_addr in settings.INTERNAL_IPS

if not is_internal:
return render_to_response( 'construction.html' )

uri = request.META.get('REQUEST_URI', '/' )

# if we're an internal ip address then find the application
urlconf
app = settings.SETTINGS_MODULE.split( "." )[0]
app_urls = app + ".urls"

# FANCY BIT IS RIGHT HERE
view, args, kwargs = resolve( urlparse(uri)[2], app_urls )

return view(request, *args, **kwargs)

About conditional view processing: ETags

[Torsten Bronger]

Hallöchen!

So far, I've used only the "last-modified" function for conditional
view processing, which worked nicely.

Now, I have a view which may switch between certain states, which
makes "last-modified" less useful.  I implemented an ETags function
for the "conditional" decorator but it didn't help at all: Opera
nevers sends "IF-NONE-MATCH", and Firefox sends only the
"IF-NONE-MATCH" of the most recent version of the page, which is no
more useful than "last-modified" alone.

Do I have to switch on further header tags in oder to trigger useful
browser behaviour in this case?  Or should it be enough to set the
ETag function in @conditional(...)?

At the moment, I wonder why one wants to use ETags at all ...

Tschö,
Torsten.

$ sudo chmod a+x /usr/lib/python-django/bin/django-admin.py
and check the first line of the script if it has a valid hash bang line.

Ah yes, I see what you mean about the dot (.)
I still seem to have no luck running the script though...

l...@leke ~/Projects/cms/django $ /usr/lib/python-django/bin/django-
admin.py startproject mysite
bash: /usr/lib/python-django/bin/django-admin.py: Permission denied
l...@leke ~/Projects/cms/django $ sudo /usr/lib/python-django/bin/
django-admin.py startproject mysite
[sudo] password for leke:
sudo: /usr/lib/python-django/bin/django-admin.py: command not found

I forgot to add, if I type import django in the python interpreter, I
don't get any errors so I guess the install went ok.

ManyToMany filtering

[Weeble]

I have a model that represents interdependent tasks. A task cannot be
started until all of its prerequisite tasks have been completed. I
want to find all the tasks which are ready to start, i.e. all their
prerequisite tasks (if any) have been completed. This is the relevant
part of the model:

class Task(models.model):
TASK_STATUS_CHOICES = (
(u"P", u'Pending'),
(u"A", u'Assigned'),
(u"C", u'Complete'),
(u"F", u'Failed')
)
status = models.CharField(max_length=1,
choices=TASK_STATUS_CHOICES)
prerequisites = models.ManyToManyField('self', symmetrical=False,
related_name="dependants")

I want to write a query that will return the set of all tasks for
which *all* prerequisite tasks are complete. So far I can only figure
out how to get the set of all tasks for which *any* prerequisite task
is complete:

Task.objects.filter(prerequisites__status=u"C")

How do I find the set of tasks for which all prerequisite tasks are
complete? Do I need to resort to writing SQL? Is there some way to
apply a filter before an annotation? For example, here I can annotate
each task with its number of prerequisites:

Task.objects.annotate(prereq_count=Count('prerequisites'))

Is there a way to make this aggregation count only the prerequisite
tasks that are not complete, i.e. to annotate each task with a count
of the number of prerequisite tasks it has for which status is not
equal to "C"?

(Note: I have also asked this question on StackOverflow. Here is the
link: 
http://stackoverflow.com/questions/1516795/in-django-how-do-i-filter-based-on-all-entities-in-a-manytomany-relation-instead

Aside: you don't need sudo for running django-admin.py.  All it does is
create some files in your current directory, since you're likely running
from somewhere in your own home directory tree you don't need sudo.

The command was not found because you put a dot at the beginning of the path
to the executable.  That makes the path relative to your current directory.
Start the path with / and it will be absolute and should work.

First tutorial - Not off to a good start :(

[Leke]

I've just installed python-django from my ubuntu repositories and
tried my luck at the tutorial here:
http://docs.djangoproject.com/en/dev/intro/tutorial01/

I tried running django-admin.py startproject mysite but discovered it
not to be on my system path.
The tutorial says "If it’s not on your path, you can find it in site-
packages/django/bin, where `site-packages` is a directory within your
Python installation." but this location doesn't seem to exist.

I did find it here /usr/lib/python-django/bin/django-admin.py and
tried to run the specified command like so...
sudo ./usr/lib/python-django/bin/django-admin.py startproject mysite

which returns...
sudo: ./usr/lib/python-django/bin/django-admin.py: command not found

I'm not a seasoned linux user, but i can't see what I'm doing wrong
here. Could somebody point me in the right direction?

Thanks.

A question about model form inheritance

[Vasil Vangelovski]

Lets say I have one form which inherits from ModelForm and a second
one that inherits from the first one. What I want to do is add 2
fields in the second form, the fields are bound to the properties of
the model. Which would be the best way to do this?

Example:

the model has fields: name, content, price, currency...

I want the BasicForm class to have only the name and content fields
and the PriceForm which inherits from BasicForm to have the fields
from the first one + price and currency.

This example is oversimplified, in practice my model has at least 10
fields and I'd have at least 4 different forms which would inherit
from the BaseForm and will be used depending on the category of the
model instance.

Please post the actual code that's not working. This should work

Re: OperationalError: unable to open database file, when saving existing object

[pigmalione]

For what it's worth, I found some kind of solution.

Apparently, running under a user administrator account in Windows
causes this kind of permissioning issue. If I enable the windows
hidden administrator and work under that account, this issue
disappears. A bit annoying.

Re: Sites module, URLs and templates

[Kristaps Kūlis]

Hi!
 You can make settings for each site easily
first_settings.py
from settings import *
SITE_ID = 1
TEMPLATE_DIRECTORIES = ( [ ] )
[ other settings, which needs to be overrided ]

you can also override urls, etc with revelant settings.

if you want to use manage.py, you will need to use copy manage.py or patch
it, because by default settings path is hardcoded in it.

Sincerly yours,
Kristaps Kūlis

Re: Will it lost some features(middleware/contextprocessor) of Django when using Jinja2 ?

[Kristaps Kūlis]

Hi!
 You can use RequestContext (and also middlewares and context processor).
Just pass it to jinja2 render method like this
template.render(**context)

See this blog post:
http://lethain.com/entry/2008/jul/22/replacing-django-s-template-language-with-jinja2/

Have you looked at django-multilingual (in google groups)? It provides 
more or less automatic translation system.
