But that just means you'll need to explicitly set cascade on those models you *do* want to cascade delete. And, IMO, the vast majority of foreign key use cases do benefit from an auto cascading delete. For the specific Links/Groups example, personally I'd just do it with a many to many relation. It's entirely feasible that in the future, Links will need the ability to associate itself to multiple groups. For now, I'd just limit a link to one group via some custom validation. -- --- David Zhou [EMAIL PROTECTED] --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

What about making it a list of tuples, and including a type?
{'articles': [('single', ),
('multiple', {1: , 2: }),
('single', )]}
Then you could just do a {% for type, article in articles %}, and have
a conditional on the type.

I'd need to check Django's template code to see if this is possible,
but one possibility is to give the decoration a "block" parameter, to
render a specific block from a template. So you could have something
like:
@render_view('js', 'template.html', block='js_block')
def view:
pass

That's basically what Alex was doing. The issue was how to render
different front-end code given that a single list has different
'types' of renderings.
My way put that logic into me template, but ideally, as Bruno said,
each 'type' should be able to dispatch its own specific render.

Re: serving static file via django
I was initially thinking that if you knew which pages you wanted to track, you could capture those requests via signals, rather than via requets to a file. But if it's an explicit requirement to track hits to that file, then that wouldn't work. Is the file a transparent gif that's solely used to track hits? Is there any reason you can't track your hits in views prior to template rendering?

Re: Why are models referenced without a capital letter in templates
The key is the sentence above that snippet on that page:
"Given the context variable poll"
'poll' is a variable passed into the template context. If you called
that variable 'a_poll', you could've done:
{{a_poll.question}}
As for choice, notice the line:
{% for choice in poll.choice_set.all %}
It's populating the choice variable with the items in choice_set.

There's several ways you could approach this:
1. Create a new template tag that takes in a person object and spits
out the age. For example, {% get_age p %}
2. Add a current_age method to the Person model, that returns the
current age. For example {% p.current_age %}
3. Return a list of tuples in your context processor:
return {'borntoday': [(calculateAge(p.date_of_birth), p) for p in
Person.objects.filter(date_of_birth__month=date.month,
date_of_birth__day=date.day)]}
Then in your template:
{% for age, person in borntoday %}
Current age: {{age}} for person {{person}}
{% endfor %}
Personally, if the current age of a person is something you'll be
using often, I'd add it to the model.

When do you suggest the current age columns should be updated? Yeah, I meant what Thomas said. Add a method to the model that calculates age.

You can also do:

Which, IMO, is slightly more clear.

Your perpetual grouchiness aside, not in any substantial way. Will the update be new online errata? Or a brand new printed version? Or perhaps a brand new volume?

You need to use a more recent version of Django. Safestring was
introduced after 0.96. See:
http://code.djangoproject.com/browser/django/trunk/django/utils
vs.

That's a Python dictionary, with 'my_meeting' as the key, and the

Can you post the relevant view and template code?
But if it's just those fields, why not refer to them explicitly? Such
as:
{{dict_variabe.name}} or {{dict_variable.phone}}

Re: django web hosting
60 megs is kind of low for djangohosting.ch's higher plan -- webfaction, for example, gives 80 mb memory with their lowest plan. I also really dislike hosts that claim "unlimited" bandwidth, and then say in the fine print that "unlimited" really means no more than 200gb a month. In fact, djangohosting.ch's terms of service flat out declares that any usage over 200gb is considered "excessive". Hardly unlimited. It also doesn't appear to offer PostgreSQL as an option -- the front page only lists MySQL.

You're not really modifying django, since you can include the templats in your templates folder, and override them.

Sounds like you just need to define that method for the S3 backend.
It's falling back on the base method that spits out the exception.

Re: Removing fields in a form subclass
I would, but in this case, I want to remove a field in an external app (specifiaclly, django-registration). I suppose I could extract all the relevant parts out of the form class in django-registration and paste it into my own form, but that seems really redundant. Basically, the user's name is autogenerated from the email field, so I want to remove the username field from the django-registration form. Though I suppose if there's no good way of doing it, I'll just have to copy out the relevant bits into a new form. -- dz On Fri, Feb 20, 2009 at 7:20 PM, Malcolm Tredinnick wrote: > > On Fri, 2009-02-20 at 10:15 -0500, David Zhou wrote: >> Suppose I had this form: >> >> class BaseForm(forms.Form): >> field1 = forms.CharField(...) >> field2 = forms.Charfield(...) >> >> And then in a subclass, I had: >> >> class SubForm(BaseForm): >> field1 = forms.EmailField(...) >> >> What's a good way to remove field2 in SubForm? > > Wrong question.

Re: Why won't my form validate?
It builds up on the things mentioned in the documentation for normal forms.

I haven't tried it, but it shouldn't be hard. Subscribe to the
relevant signals for whatever you want to track, and use a Python
Twitter library to post to the Twitter account.
I've used Mike's module at: http://mike.verdone.ca/twitter/ previously
to great success. To post something an account with that module:
import twitter
t = twitter.api.Twitter('username', 'password')
t.statuses.update(status="This is the tweet.")

Re: logic in templates
The easiest way is probably moving that list to the view. For example
customers = Customer.objects...
sellers = Seller.objects...
filtered_list = [pair for pair in zip(sellers, customers) if
pair[0].customer_id == pair[1].id]
Then pass filtered_list into the template context. Inside the
template, you could do:
(Assuming Django >= 1.1)
{% for seller, customer in filtered_list %}
{{ seller.name }} {{ customer.name }}
{% empty %}
No customers.
{% endfor %}

Re: Using glovar vars
For what you describe, you're not looking for "global" variables in the sense that you want some value persisted in the same process. You're looking at session variables, which are variables persisted for a specific user session. See: http://docs.djangoproject.com/en/dev/topics/http/sessions/ Honestly though, the easiest way that I can think of is just to use separate URLs. That way, a user could easily use the PC version if he desires. -- dz On Mon, Aug 17, 2009 at 3:28 AM, Steve Patrick wrote: > > I`ve got an application developed for PCs and I want to make it > available for mobile devices.

If you're using at least Django 1.1, you can use the empty tag:
http://docs.djangoproject.com/en/dev/ref/templates/builtins/#for-empty
For example:
{% for item in projects %}
{% include projects.html %}
{% empty %}
There are no items in the project.
{% endfor %}

For every image uploaded, add a new task to the queue detailing where the image is located. Then have a separate image processing service running somewhere, ping the queue for new tasks, and sync the processed image to your static server(s). If you really want to store uploaded images directly to the database in blobs, look into writing a custom storage backend: http://docs.djangoproject.com/en/dev/howto/custom-file-storage/ That will lessen syncing issues without needing a task queue, but will make your db server work harder. -- dz --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
