This is the same strategy I've used to filter ForeignKey fields on the
current user. If you're using class based views you should override
get_form_kwargs() to add the user parameter to the form's __init__().

It's a little trickier if you want to make this work in a ModelAdmin
subclass though. I don't see a similar method to override. What I've
done is to override ModelAdmin.get_form() like this:

def get_form(self, request, obj=None, **kwargs):
form_class = super(MyModelAdmin, self).get_form(request, obj, **kwargs)
class _Form(form_class):
def __init__(form_self, *args, **kwargs):
super(_Form, form_self).__init__(user=request.user, *args, **kwargs)
return _Form

Overwrite the constructor of the form (__init__), pass the user or whatever
parameters you may need and overwrite the choices of the field in the body
of the method.

Choices as a callable.. but no parameters?

[Steve Hiemstra]

I am trying to build a form with dynamic choices. e.g., the choices should 
depend on the user.

https://docs.djangoproject.com/en/1.8/ref/forms/fields/#choicefield

Says choices may now be a callable, and sure enough it is called in `
django/forms/fields.py(818)` – but without any parameters.

How can I get access to the current user, view, or any bit of context.

Yes, nice/renice and their I/O friend ionice (in my Debian
installation, it's part of the "util-linux" package) work quite
nicely.  It's the memory-limiting that I wish would work.

Yes, I suppose you could have a watch-dog that will monitor memory
usage and then kill the process.  I'd rather the process get an
out-of-memory error if it tried surpassing a set threshold (what
ulimit is *supposed* to do).

upgrading from Django 1.6 and south to Django 1.8

[Scott Hostovich]

I'm upgrading from Django 1.6 and south to Django 1.8. 

Following the instructions 
at: 
https://docs.djangoproject.com/en/1.8/topics/migrations/#upgrading-from-south 
seems to work initially but then realize that the user model wasn't 
updated: 
https://github.com/django/django/tree/1.8/django/contrib/auth/migrations.

I am using a custom user model but it only tacks on a field and some 
properties. Anyone else come across this?

I moving from Django 1.6 and south to Django 1.8. I followed the 
instructions 
at 
https://docs.djangoproject.com/en/1.8/topics/migrations/#upgrading-from-south

Re: Putting Limits on Memory and CPU Usage in python ?

[François Schiettecatte]

I did a little research on this and found cpulimit, you can also use nice and 
renice, and (on fedora core 21 at least) you can do 'cat /proc/###/status’ 
where ### is the process ID which will give you memory stats on a process. Not 
ideal but you can wrap all of these in some python to make it easier to manage.

I know I've wanted it to help prevent malicious data that could suck
up my RAM and push things into swap.  Absent "ulimit -a", I've had to
work around it with extra care to ensure that huge files or pessimal

Choices in DecimalField - django 1.8.

[Elton Pereira]

In the model below, using the Django admin, no matter what value I choose, 
it always displays the default value. But writes the correct value in the 
 database. Am I doing something wrong or is this a bug?

TENSAO_220 = Decimal(220)
TENSAO_110 = Decimal(110)
TENSOES = ((TENSAO_220, '220 volts'),
   (TENSAO_110, '110 volts'))

class Equipamento(models.Model):
nome = models.CharField(max_length=128)
  tensao = models.DecimalField(max_digits=8,
   decimal_places=3,
   choices=TENSOES,
   default=TENSAO_220)

Thanks!

You could specify the full path to the commands in your script, e.g.:
/usr/bin/sed, or where every they are on your system.

Question about run bash scripts on Django-Python

[David Pineda]

Hello
I'm a begginner in django and i need to work with a form (send a file) and
when the file it's ok run a bash scripts to process that.

I investigate and the common recomendation si use 'subprocess'  an 'sys'
So, i can set the path with de bash app, but the system only recognize the
'echo' command but the another like grep, awk or sed they say 'command not
found'. eg:

"home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 70: xlsx2csv: command not found
/home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 71: xlsx2csv: command not found
/home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 72: sed: command not found
/home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 73: sed: command not found
/home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 74: sed: command not found
/home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 77: awk: command not found
/home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 77: sed: command not found
/home/david/Documents/WEB_PROJ/gestion_docs/procesa_fl/procesa_sse/extrac_data_oficial.sh:
line 79: sed: command not found"

So,  i think the bin path it loose when i run from django, and in this
point i'm confused.

How to solve it?

Thanks, very thanks!

Re: Testing request parameters in Django (“+” behaves differently)

[Eneko Illarramendi]

Thank you Tom.

Somehow it seemed strange to test this view using client.get('/page/', {
'filter': 'one and two'})
but I get why it is like this.

Cheers,
Eneko

The arguments in a query string are urlencoded. Spaces are urlencoded
as '+'. Django's request.GET is a dict like object with the query
string arguments decoded.

The test client takes a dictionary of raw strings, not urlencoded
strings. If you like, you are telling it to test the URL
'/page/?filter=one%2Band%2Btwo', as '+' is urlencoded as '%2B'.

Django is consistent, the test client takes raw un-encoded strings,
and request.GET delivers raw un-encoded strings.

Cannot delete with overridden ModelAdmin.save_formset()

[Carsten Fuchs]

Dear Django fellows,

I use a ModelAdmin.save_formset() method exactly like in the Django Admin 
documentation:
https://docs.djangoproject.com/en/1.8/ref/contrib/admin/#django.contrib.admin.ModelAdmin.save_formset

This is the exact code:

def save_formset(self, request, form, formset, change):
if formset.model == AUB:
instances = formset.save(commit=False)

for instance in instances:
# For testing, intentionally do nothing else here!
instance.save()

formset.save_m2m()
else:
return super(StaffAdmin, self).save_formset(request, form, formset, 
change)


The problem is, if I check the "delete?" checkbox of an AUB inline instance in order to 
delete it, there is no error, but the instance is not deleted.


Why is this, and what can I do please?

Many thanks and best regards,
Carsten

Re: Django Performance

[jogaserbia]

You might want to start by posting what you have learned so far (with some 
effort shown). Otherwise, you are asking people to complete your homework 
for you.  Otherwise, post most specific questions for clarification.

Serialize QuerySet Q (not the result)

[guettli]

We want to store the QuerySet query (not the result) some how.

Background: users should be able to save a complex query as "my favorite 
query".

Pickling querysets is possible, but version updates are not supported:

  
https://docs.djangoproject.com/en/1.8/ref/models/querysets/#pickling-querysets

Simple queries (without OR) could be saved as dictionary.

I have in mind some mini language which enables to store Q object instances:

 Q(foo='bar', blu='bla') | Q(foo='x', blu='y')

And ordering 

Before reinventing the wheel, I want to ask if someone has seen or done
something like this before.

I could not find an existing project. But maybe I used the wrong keywords 
for
my favorite search engine.

Regards,
  Thomas Güttler

JSON to relational database

[ankit . rana]

Hi everyone,
i had one json data like this to table say "data"
 
{
id:##,
name:{fname:##,lname:##},
class:##,

column of data table or make another table having foreign key and multiple 
courses.
what i want to know is that does django provide way to do it or i have to 
do it manually..because actual data with me is very big..

Re: Django, JavaScript, Python, HTML : Print on html a variable running on python file

Hi, I'm using Django 1.7.2, Python 3.4.

My formatted question is *HERE on Stack Overflow

I hope someone can help me , I do not know how to proceed.

noramlly you have a template for an URL.
The template is generated by a view.
Views are python functions.
- You should call your python function from a view, the function must
  return your variable to the view function.
- The view should return your variable to the template.
- The template should be able to display your variable.
