Accessing Child Meta Attributes from Abstract Model Class

[Brett Epps]

Hi,

I've got an abstract base class like this:

class Base(models.Model):

class Meta:
abstract = True

def save(self, *args, **kwargs):
print dir(self.Meta)
super(Base, self).save(*args, **kwargs)

and a child model class inheriting from it like this:

class Child(Base):

class Meta:
verbose_name_plural = "children"

When save() is called on an instance of Child, Base.save() prints the
attributes of Base.Meta instead of Child.Meta (as I may be wrongly
expecting).  I have tried changing Child.Meta to extend from Base.Meta
with the same result.

So far, the workaround seems to be to use self._meta in Base.save()
instead of self.Meta, which allows me to access the attributes of
Child.Meta.  I've noticed that the django-mptt project (on Google
Code) does this.  Is this the correct way for a base class to access a
child class's Meta attributes?

Re: django.core.handlers.wsgi not found

[Brett Epps]

Sometimes it can help to print sys.path in your WSGI file.  (The output
should end up in the apache error log.)  That should tell you where Python
is looking for modules.  If the Django install path is not listed, you may
need to reinstall Django.

How was Django installed originally?

Re: Dynamic settings variables (dynamic global variable)

[Brett Epps]

I'd recommend caching the data using Django's caching framework and either
the local memory or memcached backend.  To update the cache, write a
management command that runs periodically as a cron job.  (If you find
yourself needing more sophisticated background task management, check out
Celery.)

Re: Django setup on Win7 - can't import some things

Hi Bob,

It sounds like you're using the 1.3 or later version of the tutorial.
Class-based generic views were added in 1.3.  Try this link for the
correct version:

https://docs.djangoproject.com/en/1.2/intro/tutorial01/

(Note the 1.2 in the URL.)

Hope that helps,

Re: What is the simplest way to install MySQL-python on Lion 10.7 with Xcode 4.3?

[Brett Epps]

I think your problem might be solved in this SO post:

http://stackoverflow.com/questions/6383310/python-mysqldb-library-not-loade
d-libmysqlclient-18-dylib

By the way, I'd highly recommend using Homebrew instead of MacPorts and
pip/virtualenv instead of sudo easy_install.

Re: How to generate common blocks?

Consider writing custom template tags for the common parts (assuming
they're dynamic).

Reykjavik and Tromsø are not that cold by the way. Reykjavik has an average low

Re: Simple input forms which show more than one row - easy/possible in django?

[Brett Epps]

Hi Chris,

Once you've defined a model for your data, you can use a ModelForm [1] to
automatically generate a form for that model.

You might also want to check out the admin site [2], which displays data
in a tabular format similar to what you describe.

Re: Combining Querysets from different, but similar models

[Brett Epps]

I had a similar need and solved it with a separate table of activity feed
items.  Here's the code for the Item model:

class Item(models.Model):

object_id = models.PositiveIntegerField(db_index=True)
content_type = models.ForeignKey(ContentType)
content_object = generic.GenericForeignKey('content_type', 'object_id')
...
[your common feed item fields go here]

Then I ensured that each model that could show up in the activity feed
added a new Item object in its save() method.  The result is that you can
pull the feed with one query, which could help a lot if you're mashing
together several models.  The downside is that you need to make sure the
items table stays in sync with the data from the models it is merging
together.

Re: encrypt and decrypt data in django.

[Brett Epps]

Hi Nghia,

The common pattern is to extend django.contrib.auth.models.User by creating 
your own "profile" model with the fields you need [1].  Then you can set the 
AUTH_PROFILE_MODULE setting and access the profile from User objects through 
the User.get_profile method.  The Python standard library has modules related 
to encryption [2].

  1.  
https://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users
  2.  http://docs.python.org/library/crypto.html

Hope that helps,

Re: setting site-name variable

[Brett Epps]

Which "site-name" variable are you referring to?  Usually you'll want to
place global settings in your settings.py file.  Then you can access them
elsewhere like this:

from django.conf import settings
print settings.[name of setting]

Also, you might be interested in the sites framework [1], which is useful
for running multiple websites using the same Django project.

Re: memcached not working with django

[Brett Epps]

Have you configured Django to use memcached in your CACHES setting?  If
so, can you post that?  Also, what are you caching?

Re: Help with implementing dynamic views/models

[Brett Epps]

I may be misunderstanding your question, but it sounds like you need to
use Page.objects.get or Page.objects.filter (in your view function) to
look up the particular objects that you want to send to the template.

Re: Help with implementing dynamic views/models

[Brett Epps]

The direct_to_template() function can take an extra_context keyword
argument (a dict). So:

direct_to_template(request, template='blah.html', extra_context={'foo':
bar})

Would let you use {{ foo }} in a template to output the value of the
variable bar.

By the way, as a replacement for direct_to_template, there's
django.shortcuts.render [1], which is a little more concise.  (Usually,
you use direct_to_template in urls.py, since it is a full-fledged generic
view function.)

1. 
https://docs.djangoproject.com/en/dev/topics/http/shortcuts/#django.shortcu
ts.render

Hope that helps,

Re: Help with implementing dynamic views/models

Try it with {'page': page} as your extra_context. The keys in a context
dict should always be strings.

Re: Add to database

[Brett Epps]

I think you need to look up a specific Proyecto object before trying to
add users to it. So:

proyecto = Proyecto.objects.get(...)
for i in request.POST.getlist('usuarios'):
usuario = User.objects.get(id=i)
proyecto.usuarios.add(usuario)

Hope that helps,

Brett

Re: Help with implementing dynamic views/models

[Brett Epps]

The reason for that output is that page is a list, not a single object.
If you want a specific page, use Page.objects.get instead of
Page.objects.filter.

Re: django-admin py extension on fedora

[Brett Epps]

Perhaps Django is packaged differently on Fedora.  Did you install it
using yum?  I'd recommend installing with pip to avoid such issues, and to
ensure you're getting the latest version.

Re: Django as a Standalone Desktop Application

Hi,

Could you tell us more about the utility you want to create?  It sounds like 
Django might not be the appropriate tool in this case.

Subject: Django as a Standalone Desktop Application

Hi,

I want to write a little utility for somebody and I would like to use Django to 
develop it.

At the moment the utility does not need/or never will have to be running on a 
web server.

I would like to build a little standalone desktop app, so that I can send the 
Django App and everything that is needed (Python,MySQL/SqLite) with one 
Installer/Folder for Windows.

Searching google I found 
“dbuilder.py”

Looks like what I am looking for, but I was wondering if you have any 
experience or suggestions. Maybe there is a newer tool or some state-of-the-art 
way to do it? dbuilder.py was last updated in 2008.

Something like XAMMP or MAMP with support for python and mysqldb would be nice.

Thanks!

PS: I am developing on Mac OS X but could use a virtualized Windows if there is 
need.

Re: update other objects when saving an object:

[Brett Epps]

Hi Tim,

The problem is your use of the self keyword when trying to get at the 
ChapterMembership manager.  Instead of:

chapters = self.objects.filter…

Try:

chapters = ChapterMembership.objects.filter…

Hope that helps,

Brett

Subject: update other objects when saving an object:

Hi,
I've modeled a Book that has Chapters, with each Chapter having an ordering 
'sequence'.
So when someone decides the first chapter in the book should become the third, 
they can just change the sequence number.
That's fine, but when that happens, I want the other chapters to automatically 
change their sequence to reflect the change.

To accomplish this I thought I could add a custom 'save' method to my Chapter 
model, but I get the message:
'Manager isn't accessible via ChapterMembership instances'

My code seems straightforward enough:

class ChapterMembership(models.Model):
chapter = models.ForeignKey(Chapter, blank=True, null=True)
book = models.ForeignKey(Book, blank=True, null=True)
sequence = models.PositiveIntegerField()

def save(self):
chapters = self.objects.filter(book=self.book) # get all instances for 
the related book
sequences = [x.sequence for x in chapters] # a list of all the sequence 
numbers
if self.sequence in sequences: #if we have a duplicate sequence take 
care of it
for chapter in chapters:
if self.sequence == chapter.sequence:
chapter.sequence = chapter.sequence + 1
chapter.save() # makes this a recursive method
super(ChapterMembership, self).save()

I suppose I'm missing something basic, but I haven't seen an example like this 
in my searches.
Can anyone see what I'm doing wrong?
thanks,
--Tim

Re: Comparing two ManyToMany fields for same entries

[Brett Epps]

I'm going to guess that my version is slow since a new query would be run
for each row returned by the initial one.

Check out an app called django-debug-toolbar.  It has a view that will
show you all of the SQL queries generated as a page is built.  It will
also tell you how long each query took to run.  This should allow you to
compare the three methods.

Re: Reg. Basic django.db.models

[Brett Epps]

Hi Ganesh,

Here are some examples:

Filter: SELECT * FROM device WHERE locked = true - returns a QuerySet
which can be evaluated as a list of Device objects
Get: SELECT * FROM device WHERE id = (value of id variable) LIMIT 1 -
returns a single Device object
All: SELECT * FROM schedule - returns a QuerySet which can be evaluated as
a list of Schedule objects

These are only approximations.  For example, get() does not imply a
"LIMIT", since Django looks for cases where multiple objects were returned
and throws an exception.  But hopefully this helps you understand how the
ORM maps to SQL queries.

Here's the relevant part of the documentation [1], in case you haven't
found it yet.

Re: firstof as

[Brett Epps]

Instead of adding a template tag, you could handle this in the class for
obj.  Just have get_votes() cache its result and use the cached value
after the first time get_votes() is called.  In the template, always call
get_votes().

Re: setting up openlayers proxy.cgi

[Brett Epps]

Django itself won't run a CGI script for you.  You'll need to run it with
another web server like Apache or nginx.  (Usually the default
installation of Apache has a cgi-bin directory where you can place CGI
scripts.)  You can run one of these servers at the same time as running
manage.py run server, but you'll need to use different ports.

Hope this helps,

Brett

Re: Django + ajax waiting page, can not redirect to result page

I think the problem is that your  tag is incorrect. You're using
the same one to load jQuery and to add your code, so your JavaScript is
