Multi-table inheritance with parent that can be null?
Can you make a model that inherits from another model with multi-table inheritance and that can have a null parent?

Re: url template tag problem
Thanks Malcom, I changed the views function name but still got the
same error so I don't know if it's a bug. I will try to take a closer
look at it, but I really don't know why this may happen. Does anybody
else has an idea?
Thank you,

url template tag problem
Hi,
I get the following error when trying to use the {% url %}
templatetag. I have read the documentation several times but cannot
understand where is the problem:
AttributeError at /c/albums/wonderful-world/
'str' object has no attribute 'callback'
My urls.py:
urlpatterns = patterns('',
url(r'^artists/(?P[-\w]+)/$', view_artist, name='view-
artist'),
My template:
...
{% url view-artist slug=album.artist.slug %}
...
I have tried also {% url view-artist album.artist.slug %} but get
still the same error :(
Any ideas why this might happen?
Thank you!

Re: saving many2many relations
Thank you Collin, I tried that before posting in this group but the
same thing happened: I get no errors when saving but Tags still remain
not asociated with Receta.
class Receta(models.Model):

from django.template.defaultfilters import slugify
tags = self.etiquetas_text.split(',')
super(Receta, self).save()
for tag in tags:
etiq, created =
Tag.objects.get_or_create(nombre=tag,slug=slugify(tag))
self.etiquetas.add(etiq)
Anyone knows where the problem is?

saving many2many relations
Hi,
I would like to get a list of tags separated by a comma and be able to
save them as related objects for the current object. Currently I have
this code. When saving a Receta object it creates the tags objects if
they doesn't exist yet and it should save the relations between Tags
and Receta, but they are not saved. The code doesn't give any errors
but the Tag objects are not linked to the Receta object after saving
it.
Any ideas why this happens? Thank you!!!
class Tag(models.Model):
nombre = models.CharField(maxlength=20)
slug = models.SlugField(prepopulate_from=("nombre",),unique=True)
class Receta(models.Model):
user = models.ForeignKey(User)
nombre = models.CharField(maxlength=50)
slug = models.SlugField(prepopulate_from=("nombre",),unique=True)
etiquetas =
models.ManyToManyField(Tag,related_name='recetas',blank=True)
tags_text = models.CharField(maxlength=150)
def save(self):
from django.template.defaultfilters import slugify
tags = self.tags_text.split(',')

for tag in tags:
etiq, created =
Tag.objects.get_or_create(nombre=tag,slug=slugify(tag))

User profile views - Does something like this make sense?
I want to show the user the latest users that have seen his profile. So everytime a logged user views another user's profile a ProfieView object is stored in the database (or the date is updated if the user that is viewing the profile has already viewed it before). I know this can make the database grow too much, so I think I can run a cron script daily that deletes all profile views older than a week (see clear_old method).

Django slows file uploads?

Saving info about viewed tags
Hi, I have an Objects Model and a Tags Model with a M2M relationship between them. I want to update info about the tags of the object visited by the user updating it everytime the user requests an Object. Is it a crazy idea? I want to know wich tags are the most viewed by the user and wich are the most recent he has view so that I can recommend him Objects that have also such tags (objects that are related to the ones he is interested in). This is my main idea how the models should be: === class MyObject(models.Model): tags = models.ManyToManyField(Tag) etc. class Tag(models.Model): etc... class RelationModel(models.Model): my_object = models.ForeignKey(MyObject) tag = models.ForeignKey(Tag) times_viewed = models.PositiveIntegerField() latest_view= models.DateTimeField() Problems I see: === - Lets say I have 30 tags for each object, I need to create_or_update 30 rows everytime a user requests an object. That could be a bottleneck :( - The relation table can be very big: 100.000 users x 2.000 tags each user = 200.000.000 rows in the relation table I should limit it to lets say 50 tags per user and in each update overwrite the less viewed and older tags with the new ones. -> more updates on every request :S - Is this the better way to do what I want to do? Any ideas? Thank you for your help. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

stats for object views
Hi, I have created a stats field (PositiveIntegerField) in my objects and I want to use it for saving how many times the object has been showed to visitors but I don't want to make a database request everytime an object is viewed due to performance issues. I have seen http://code.djangoproject.com/wiki/ProfilingDjango and I think I could save a profile for each url so I could use a cron job that executes a python script every 30min that updates the objects views in the database with the information of the profiles files.

generic views serialization support (json, xml, etc.)
Hi, are there any plans to add serialization support to generic views? I think it won't be difficult to implement it because generic views are already programmed and they should only get one extra parameter to know which type of document they have to return (html (default), xml, json). It's just remembering what James Bennett said in this ticket: http://code.djangoproject.com/ticket/2553 I think that would be very useful for ajax apps with the advantage that it doesn't bind you to a specific ajax framework (like rails does). thank you --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

templatetags: returning more information of every object in a list of objects (not only the objects)
Hi,
I have a templatetag that returns a lists of objects. The problem is I
want to include another information for every object: I want to include
the number of related objects for every object of a ManyToMany
relationship. The model ArtistaTag has a ManyToMany relationship with
Artistas. So I use:
tags=['']
nums=['']
q = ArtistaTag.objects.all()
for tag in q:
num = tag.artista_set.count()
if num >= 1:
tags.append(tag)
nums.append(num)
context['lista_tags'] = tags
context['nums'] = nums
return ''
So that I become 2 lists, one with the objects (tags) and the other
with the number of related objects (nums) but I don't know if this is
the right way to do that an more important: I don't know how to get the
number of every object in each object iteration in my template:
{% for tag in lista_tags %}
{{ tag.name }}
how to get the num for this tag?
I don't know if you understand me, please send any comments and I will
try to clarify my problem.
Thank you!!!

def _manipulator_validate_filefield(self,field_data,all_data):
if not self.archivo.endswith(".mp3"):
raise validators.ValidationError, 'Please select an mp3
file.'
I thought that was enought to validate the file but it doesn't validate
anything when saving a new object, so what else should I do?
thank you!

urls and generic views with 2 slugfields
Hi, I've got 3 models: Artist, Album and Song. For getting an artist info I use: (r'^artists/(?P[-\w]+)/$', 'django.views.generic.list_detail.object_detail', dict(info_dict, slug_field='identificador')), I want an url like www.mysite.com/artists/black_eye_peas/albums/album_name for getting all songs of that album that belongs to that artist. how could I do that? problem: it contains 2 slugfields thank you! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Easy thumbs in your models
I needed to make this and I hope it helps some people there. Features:
- Generate thumbs from ImageFields when creating the models
(file.jpg -> thumbnail saved as: file.thumbnail.jpg)
- Showing thumbs in admin
- Deleting thumbs when deleting the object
In your models.py:
from PIL import Image
import glob, os
thumb_size = 90, 90
class MyClass(models.Model):
foto = models.ImageField(upload_to='my_photos/',blank=True)
def save(self):
file_path = self.get_foto_filename()
# is there a photo?
if (file_path):
file, ext = os.path.splitext(file_path)
im = Image.open(file_path)
# thanks to PIL ;)
im.thumbnail(thumb_size, Image.ANTIALIAS)
# save thumbnail
im.save(file + ".thumbnail.jpg", "JPEG")
super(MyClass, self).save()
def delete(self):
file_path = self.get_foto_filename()
# There's is a file?
if (file_path):
file, ext = os.path.splitext(file_path)
thumb = file + ".thumbnail.jpg"
# if there is a thumb we delete it
if(thumb):
os.remove(thumb)
super(Artista, self).delete()
def show_thumb(self):
# get the url of the file
file_path = self.get_foto_url()
# add .thumbnail between file and extension
file, ext = os.path.splitext(file_path)
file = file + ".thumbnail.jpg"
if(file_path):
return "" % (file_path,file)
mostrar_thumb.allow_tags = True
mostrar_thumb.short_description='Foto'
class Admin:
list_display = ('show_thumb',)
==
That's all. If you make any improvements let me know them ;)

Re: SlugField is not unique?
Hi Gábor, I think it's just for making it more flexibile, but in the most cases you will use unique=True in your SlugFields. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Error always when deleting objects with ManyToMany (self) relationships
Hi,
I get always the following error when deleting objects with
ManyToMany(self) relationships in the admin. Have tried with different
models and always getting the same error. Doesn't the admin interface
support ManyToMany relationships with the same table?
TypeError at /admin/person/person/2/delete/
getattr(): attribute name must be string
This is the model:
=
class Person(models.Model):
name = models.CharField(maxlength=20)
friends = models.ManyToManyField('self',blank=True)
idols = models.ManyToManyField('self', symmetrical=False,
related_name='stalkers',blank=True)
def __str__(self):
return self.name
class Admin:
pass

error when deleting model with ManyToManyField
TypeError at /admin/artistas/artista/asdf/delete/
getattr(): attribute name must be string
this is the many to many field. when I delete it from the model
everything works well but when that field is in the model i get the
type error.
artistas_relacionados =
models.ManyToManyField('self',blank=True,related_name='artistas_rel')
Any ideas why this can be?
Thank you

Cannot have multiple projects running
Hi! I've set up django on dreamhost as seen here (http://www2.jeffcroft.com/2006/may/11/django-dreamhost/). Everything works ok with one project, but when I create another project and add another sub-domain for it following all the steps as shown on that site my browser doesn't load that sub-domain. It just stays "loading..." all the time. Any ideas why this is happening?

admin and dates...
Lets see if someone has already dealt with this problem and can help me: I want to administer appointments in admin. I have two classes: === class Client(models.Model): name = models.CharField(maxlength=30) company = models.CharField(maxlength=50) class Appointment(models.Model): client = models.ForeignKey(Client,raw_id_admin=True) when = models.DateField(core=True) hour = models.TimeField(core=True) === There is a ManyToOne relationship: I can make many appointments with every client and each appointment belongs only to one client. The problem is I cannot make an appointment with a client the same date and same time I've planned another appointment before. So I've got 2 troubles: - When creating a new appointment showing only available dates/times for selection. (perhaps with AJAX when selecting a date showing only available times for that date? but... how?) - In the appointments list view showing available days for directly adding an appointment that day (something like a timetable?) Has anyone dealt with appointments in django admin? how? Thank you!!! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
