erm... Yes, you can. The Django test suite contains an explicit
example of how this can be done. See the modeltests/model_package
tests.

Pro tip: You need to look into the "app_label" Meta argument [1].

[1] 
https://docs.djangoproject.com/en/dev/ref/models/options/#django.db.models.Options.app_label

So - again -- you *don't* get any benefits from Django from nesting an
app inside another app. Yes, the last part of the app module name
needs to be unique in your project, but otherwise, it doesn't matter
how deeply you nest your app modules -- an app is an app.

You've got app code running here that is forcing creation of a UserProfile
when the user is loaded. Likely these UserProfile objects are also being
loaded from the fixture, so the attempt to create them is generating the
"user_id" is not unique error.

This request is unclear, perhaps if you put a few more words around this
describing what you actually want to do someone could help. It doesn't make
any sense in Django to say you want an app inside an app.

You can do this with readonly_fields in admin:
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.readonly_fields

You'll need to upgrade from that ancient level of Django though,
readonly_fields were introduced in 1.2.

(Assuming the time field should be stored in the database)

Simplest, but specific for temporal fields:
class Test(models.Model) :
start_time = models.DateTimeField(auto_now_add=True)
end_time = models.DateTimeField(auto_now_add=True)
time = models.DateTimeField(auto_now_add=True)

Generally working:
class Test(models.Model) :
first = models.CharField(max_length=10, default='first')
second = models.CharField(max_length=10)

def __init__(self, *args, **kwargs) :
first = kwargs.get('first', False)
if not first :
first = self.__class__.first.default
second = first
if not kwargs.get('second', False) :
kwargs['second'] = second
super(Test, self).__init__(*args, **kwargs)

For the admin, see

for an alternate solution.

Well, this isn't completely true. As I said in earlier mail, you need
unique final part for INSTALLED_APPS.
Secondly, you can't organize models as you wish, meaning you can't do:
app/
models/
   __init__.py
   mymodel.py

The model registry can't deal with it and lots of assumptions are done
in the code based on the fact that models are in a file called models.py
inside the application directory. I tried organizing models differently
like above and manually populating the application registry with them,
but I never could get it to work completely because of code like this:
./core/management/sql.py:
app_dir = os.path.normpath(os.path.join(os.path.dirname(
models.get_app(model._meta.app_label).__file__), 'sql'))

For this reason it was more beneficial to use sub applications when
models.py grew rather big as no additional code was needed to populate
the app registry and things just work out of the box at a small cost of
having to register multiple apps in INSTALLED_APPS.

Yes, you need to create a directory named templatetags, and put your
tag library in a module inside that directory. When Django looks
parses your template and find the {% load mytaglibrary %} declaration
(which is what tells it to load the tag) it looks for a directory
named templatetag in each of apps in your project. If you don't put
your tag in the right place, Django won't be able to find your custom
tag.

Hi Russell,

Many thanks for your reply. The template tag approach looks good and I will
try to use this one.

One further question. If I am using the @register.simple_tag decorator, can
I create the view in the views.py file or do I have to create a
templatetags directory and follow the full procedure of creating a tag?

Sorry if this sounds all basic but I am quite new to this.

Thanks a lot in advance.

Re: Validation error with formwizard and formset

2012-07-21 Thread Rob 
The validation error i got was due to a custom view i wrote, and had 
nothing todo my my template etc etc. I switched back to the default example 
view provided by the Django site, and everything works.

Validation error with formwizard and formset

2012-07-21 Thread Rob 
I have a basic formwizard example from the Django 1.4 documentation:
https://docs.djangoproject.com/en/1.4/ref/contrib/formtools/form-wizard/

When I replace the forms with a modelform and a formset i keep getting 
validation errors: 
(ManagementForm data is missing or has been tampered with)

The documentation says:
WizardView supports 
*ModelForms*and 
*ModelFormSets*.
 
Additionally to 
initial_dict,
 
the as_view() method takes an instance_dict argument that should contain 
instances of ModelForm and ModelFormSet. Similarly to 
initial_dict,
 
these dictionary key values should be equal to the step number in the form 
list.

Could anybody provide me with an example? Does the validation error have 
something to do with the instance_dict?

Let say i have these forms:
class Address(models.Model):
street = models.CharField(max_length=20)

class AddressForm(ModelForm):
class Meta:
model = Address

class OrderForm(forms.Form):
Order = forms.ModelChoiceField(queryset=Article.objects.all())

OrderFormset = modelformset_factory(Order)

Child-friendly blogging app

2012-07-21 Thread Lie Ryan 
Hi, I'm creating a website that allows registered users (which are not 
is_staff) to write journals (text, images, sound, video, and uploaded 
files), and write comments to other's journals. The journals and 
comments have to be moderated by a different class of users (the 
moderators) before they appear anywhere (not all moderators are 
is_staff). The content editor used must be very simple and easy to use 
because the users will be primarily children and teenagers (8-years and 
up), and not all moderators will be technically knowledgeable (they are 
teachers). Each user (children and moderator) are associated with a 
"circle" and can only view and post contents within their own "circle" 
(only is_staff user can publish content for site-wide publication). And 
since some "circles" do not want to participate in this blogging 
functionality, the whole journalling feature will be disabled for them.


Given these requirements, if you have any personal experiences with 
using the existing blogging/CMS apps, can you recommend some existing 
blog/CMS engine that will suit the requirement? Being easy to integrate 
with other apps is a big plus (e.g. features like Django-CMS's Placeholder).


Easy-to-use content editor is a must, we do not want children to need to 
learn markups or become confused when trying to use special characters, 
e.g. <, >, &, but we do want basic formatting (also, some of the older 
teenagers might know some funny stuffs like XSS, so good security is a 
big plus).

There sure is: Use a template tag instead.

https://docs.djangoproject.com/en/1.4/howto/custom-template-tags/#simple-tags

If your custom template tag makes the random call, you don't need to
put randomly selected text or a randomly selected value into the
template context.

The template context for the 404 page isn't something that's
configurable by default, so if you *did* want to go down that path,
you'd have to write your own 404 view, and set that as your 404
handler. This isn't especially difficult to do, but the template tag
approach will be simpler :-)

Yours,
