Yes, I added the lines to the wrong table :)
Now it is working in the shell. I'll try to use 
this
 to 
make this work too in the admin.py interface.

I keep you posted, thanks for your help !

Re: Adding values in my database via a ManyToMany relationship represented in admin.py

[Louise OTT]

Ok, it is still not working. 
Django can't find the intermediate table.

And I can't put an "inlines" into an "inlines" ! My RunHasSample are 
already in a field "inlines" in the RunAdmin, so I cannot put the lines in 
an "inlines" field into the class RunHasSamplesInLine

Re: querying data from Django userena profile.

[Subhodip Biswas]

Hi all,

I have done a workaround the initial problem, all i did was add the
custom field into my apps models.py. This led to the data entered in
the custom field of signup form is shown in the edit_details page of
the user profile. However, unlike other data fields in edit_profile,
this custom field is not visible in view profile page.

Can anybody explain why is this happening and any workaround for this?

Struggling with static files

[DJ-Tom]

Hi,

I'm fairly new with Django and currently I'm only "playing around" to get a 
better feeling for the framework.

I have read the documentation and almost all of the posts here about 
configuring static files with the development server but can't get it 
working.

I wanted to modify the admin login screen to show a company logo, so I 
copied base_site.html to /templates/admin/ and added this:

   


This is how my directory structure looks like:

el_test
  el_test
static
   logo.gif
settings.py
urls.py
  templates
admin
  base_site.html

- Settings.py:

STATIC_ROOT = ''
STATIC_URL = '/static/'
STATICFILES_DIRS = (
)
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)

I also added the following to urls.py

   urlpatterns += staticfiles_urlpatterns()

The HTML in the admin logon screen looks like this, so basically the URL 
seems to be OK


  
  Test Admin


Calling http://localhost:8000/static/logo.gif directly shows a 404 error.

As far as I have understood this should work with the dev server and 
debug=true without calling collectstatic

I have also tried moving the /static/ folder around various locations below 
the project directory... 

I'm sure there is only some small thing missing...

Any help is highly appreciated :-)

Give path to your STATIC_ROOT of your static folder.

Re: Struggling with static files

Hi,

Your static folder should be declared in STATICFILES_DIRS if you want him to be 
served (see 
https://docs.djangoproject.com/en/1.4/howto/static-files/#basic-usage about 
that).

Please take care to give another name to STATIC_ROOT for production settings.

This is precisely what you shouldn't do.
The STATIC_ROOT is where files are copied to for production using the 
collectstatic command.
This is not for development and this is not where you should store your 
project's static files.

All the documentation refers to  STATICFILES_DIRS as "this is where tu put 
additional paths" with INSTALLED_APPS/static being the default path. 

If I add this to STATICFILES_DIR:

  '/el_test/static'

...the admin page login completely loses any styling because it can't serve 
the admin css files anymore
(the url's are http://localhost:8000/static/admin/css/login.css and 
http://localhost:8000/static/admin/css/base.css)

So either the documentation is wrong or I understand the word "additional" 
in a different way as the author of the documentation...

AHHH - I was missing the trailing comma after the path name... so 
STATICFILES_DIR was not a valid list.

Everthing's fine now.

Gunicorn vs Chaussette vs Meinheld

[Santiago Basulto]

Hello people. Reading about Circus[1] I ran into a couple of different 
"WSGI servers" that I haven't heard before (Chaussette[2] and Meinheld[3]). 
My question is if those are all similar to Gunicorn (and can be used 
instead of the last) or are just complementary servers.


One thing that really confuses me is this:

Meinheld claims that you can use it with Gunicorn. 

>gunicorn --workers=2 --worker-class="egg:meinheld#gunicorn_worker" 
gunicorn_test:app

And Chaussette claims that you can use Meinheld as the backend.

This is really confusing. What's the advantages of one over the other? I'm 
using Gunicorn right now and works pretty well. Have you used any of the 
others?

Re: Gunicorn vs Chaussette vs Meinheld

[Tarek Ziadé]

Oh sorry, that was the other way around - I was getting confused too :)

Meinheld can act as a worker in gunicorn, and in this case you don't use 
the meinheld web server but just its nice async features like gevent
Meinheld also provide a built-in wsgi server, that is used in Chaussette

tl;dr: with Circus and Chaussette you get a nice process management tool 
where you can manage all your processes in a single place (web 
workers,celery, redis, rabbit, elastic search etc..)

long story:  Circus is able to bind the sockets and share them with the 
processes it manages.  The advantage is that you remove one layer of 
process management

In a classical stack, if you have Gunicorn running 5 workers, and let's say 
- one celeryd and one redis running, you end up with 2 layers of process 
managers: the one you use to manage gunicorn, redis and celeryd -- and 
gunicorn that manages its 5 workers.  You end up not being able to interact 
with your web workers the same way you'd do with your other processes in 
your stack.

using Circus, you can have a single layer of processes management.  More 
explanations here: 
http://circus.readthedocs.org/en/0.5.2.1/sockets/#circus-stack-v-s-classical-stack

As for Meinheld, it can act as a standalone wsgi web server, like uWsgi for 
instance - and Chaussette offers it as a backend. And it also happens to 
allow you to bind gunicorn - which in my opinion does not make much sense 
since it's already a wsgi server.

Cheers
Tarek

I 

Initially i was using Symfony1.4 framework and i didn't liked that much but 
was good. Then when Symfony2 came i never looked back at other php 
framework with things like annotation , service classes , repository 
classes , it almost similar to Spring/Hibernate of java at enterprise level.

Now i am doing Django. But i see that Django can't beat Symfony2. The 
service classes, DI container , Annotation based routes , validations etc 
excellent to use when you get your head around.

Spring/Hibernate also doing similar way.

So is there any possibility in some djago ver2 that they can think about 
those things. I don't think it will hard if it can be done in PHP why can't 
in Pythonn

Re: My page cound not load image, help!

[Amyth Arora]

Serve the image as a static file. in your settings.py file set the
following:

STATIC_URL = '/static/'
STATICFILES_DIRS = ('/path/to/your/image/directory',) # Without a trailing
slash

and then load your image as

Re: My page cound not load image, help!

[Dae_James]

I use *ImageField*(with upload_to = 'photos') to receive user-uploaded 
images. And in my template, I want to use **(image is the object of ImageField) to display them. However, images 
can't be displayed. I think it's not about static files. If it is, what's 
the use of ImageField's url property.

Moreover, images will relate to the MEDIA_*

Static are really meant to be static, ie they won't change as long as you don't 
update your project/applications.
Media are where other files should go. Whether they are uploaded user documents 
or application generated ones, they should go there.

For moreinformation have a look there:
https://docs.djangoproject.com/en/1.4/ref/models/fields/#django.db.models.FileField
And especially the part after: "Using a FileField or an ImageField (see below) 
in a model takes a few steps:"

Only one profile type of multiple user profiles types gets created.

[Nicolas Emiliani]

Hi!

I'm trying to use different types of profiles on django 1.4, I basically
followed this :

https://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users

The thing is that the docs only apply if you have one profile type, and i
have four. Doing
some research i found that setting a base profile and inheriting from it
you can can get multiple
profile types. So this is what I did :

class HomesUserProfile(models.Model):
user = models.OneToOneField(User)

class AgentProfile(HomesUserProfile):
homes_user = models.OneToOneField(HomesUserProfile)
agency = models.ForeignKey(Agency, verbose_name='Agencia')
branch = models.ForeignKey(Branch, verbose_name='Sucursal')

class AuditorProfile(HomesUserProfile):
homes_user = models.OneToOneField(HomesUserProfile)
agency = models.ForeignKey(Agency, verbose_name='Agencia')

and then :

AUTH_PROFILE_MODULE = 'homes.HomesUserProfile'

class UserAdmin(contrib_auth.UserAdmin):
inlines=(AgentProfileInline, AuditorProfileInline)

The thing is that now the only profile that ever gets created when creating
a  user
is AgentProfile. I can't get it to create an AuditorProfile not even by
setting the agency
field on the form.

Any ideas what is going on? I'm clueless

Thanks!

Re: Adding values in my database via a ManyToMany relationship represented in admin.py

[Louise OTT]

I found where the problem is...

It is not a problem in the ManyToManyField but in the intermediate table. 
Django refused that my intermediate table doesn't have an unique id !

So, in the sql which created django, it created automatically an unique id 
named "id", but in my database I didn't create one (because the couple of 
two foreign key is usually enough).

Next time, I'll be more carefull.

Raising a ValidationError in a custom field's to_python method?

[Nicolas Dandrimont]

Hello,

I'm trying to write a custom field for use with the netaddr.EUI python
class (which allows manipulations on MAC Addresses, access to the OUI
database, and other fancy stuff).

To do so, I'm subclassing model.Field, and overriding the to_python and
get_prep_value methods. The class instantiation in to_python can raise
an exception when the format is wrong. I catch this exception and
re-raise a ValidationError.

Unfortunately, when doing a form validation, this ValidationError throws
an error 500 instead of pretty-printing the message in the form. Am I
doing something wrong?

See the relevant snippets below:

#--8<{ fields.py }>8--#
import netaddr
 
from django.core.exceptions import ValidationError
from django.db import models
 
#[...]

class MACAddressField(models.Field):

description = "A MAC Address"

__metaclass__ = models.SubfieldBase

def __init__(self, *args, **kwargs):
kwargs['max_length'] = 12
super(MACAddressField, self).__init__(*args, **kwargs)

def to_python(self, value):
if not isinstance(value, netaddr.EUI):
try:
value = netaddr.EUI(value)
except netaddr.AddrFormatError as e:
raise FormValidationError("Adresse MAC invalide: %s" % 
repr(value))

return value

def get_prep_value(self, value):
if isinstance(value, netaddr.EUI):
value.dialect = netaddr.strategy.eui48.mac_bare
value = '%s' % value
return unicode(value)

#--8<{ models.py }>8--#
 
# [...]

class Machine(models.Model):
"""Une machine"""
proprietaire = models.ForeignKey(User)
batiment = models.ForeignKey(Batiment)
nom = models.CharField(max_length=64)
ip = fields.IPAddressField()
mac = fields.MACAddressField()
creation = models.DateTimeField(default=timezone.now)
expiration = models.DateTimeField(default=lambda: timezone.now() + 
datetime.timedelta(days=90))

@classmethod
def validmachines(cls):
"""Machines valides actuellement"""
return cls.objects.filter(expiration__gte=timezone.now())

def clean(self):
"""Validation du modèle"""
# Validation Nom de machine
nom = self.nom.lower()
if not re.match(r"^[a-z0-9][a-z0-9-]{,63}$", nom):
raise ValidationError(u"Le nom de machine ne peut contenir que des 
caractères alphanumériques et des tirets")
same_name = self.validmachines().filter(nom=nom)
if self.pk:
same_name = same_name.exclude(pk=self.pk)
if same_name:
raise ValidationError(u"Nom de machine déjà utilisé")
self.nom = nom

# Validation adresse IP
if self.ip:
for net in Subnet.objects.filter(batiment = self.batiment).all():
if self.ip in net.net:
break
else:
raise ValidationError(u"Adresse IP hors des réseaux du 
bâtiment")

same_ip = self.validmachines().filter(ip=self.ip)
if self.pk:
same_ip = same_ip.exclude(pk=self.pk)
if same_ip:
raise ValidationError(u"Adresse IP en cours d'utilisation")

def __unicode__(self):
expire = u""
if self.expiration <= timezone.now():
expire = u", expire"
return u"" % (self.nom, self.ip, expire)

Getting a strange error message when setting mysql database

Hi,

After setting the following:

Not used with sqlite3.

FormWizard for shop checkout

[KentH]

Hi,

I'm trying to use FormWizard for an e-checkout application. Trying to 
perform the actual "charge" in the "done" step is problematic as you can't 
go back if the charge fails.

Is there a right way to do this?

For example of what steps look like, just imagine the steps as listed in 
the FormWizard documentation with the charging in the "done" step.

Thanks for any pointers.

Re: invalid literal for int() with base 10

[Nathan Knight]

Just so you know, it is bad practice to use "import * " when importing 
modules in python.
With many modules being used, you can run into conflicting definitions. 
Plus, it increases overhead - potentially an exponential decrease in

You are directly importing a package which is on the Python path so the 
system finds it ok. But, that package (django_tables2) apparently 
expects to be imported by some other bit of code which already knows 
where your settings.py file lives.


If you want to import it directly it needs to know where to look.

You might need a PYTHONPATH environment variable which specifies the 
path to your Django project. If settings.py lives in 
C:\webwork\djngony\project\xyz\settings.py. Then your PYTHONPATH needs 
to include C:\webwork\djngony


The traceback indicates, you need a DJANGO_SETTINGS_MODULE environment 
variable. In my example above it would simply be project.xyz
