Well, after good night sleep I've some idea.

Something like should do the trick:

Log.objects.values('thing').annotate(deletion_date=Max('modified_on')).order_by('-deletion_date')

Saving test user as a foreign key in unit tests

[jondbaker]

I have a Tasting model with an 'author' field that is a ForeignKey to the 
User model. Within my unit test I'm attempting to create a test user, and 
pass that user object as the author of a test Tasting, but I keep getting 
the following error: "IntegrityError: tastings_tasting.author_id may not be 
NULL"

*models.py*
class Tasting(models.Model):
notes = models.TextField(blank=True)
author = models.ForeignKey(User, editable=False)

*forms.py*
class TastingForm(ModelForm):
class Meta:
model = Tasting

*views.py*
def create_tasting(request):
if request.method =='POST':
form = TastingForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/tastings/')
else:
form = TastingForm()
return render_to_response('tastings/create.html', {
'form': form
}, context_instance=RequestContext(request))

*test_views.py*
class TestPostCreateTasting(TestCase):
def test_auth_response_valid_data(self):
client = Client()
user = User.objects.create_user('test', 't...@test.com', 
'testPassword')
client.login(username='test', password='testPassword')
tasting = {
'notes': 'What a great beer',
'author': user,
}
response = client.post('/tastings/create/', tasting)
self.assertEquals(response.status_code, 200)
tastings = Tasting.objects.all()
self.assertEquals(len(tastings), 1)
client.logout()

Python Library for Audio Files - Clipping mp3/ogg formats

[BGMaster]

Hi,

I know this isn't a django specific question, but does anyone know of
a good python library or module for clipping/cutting an mp3 or ogg
file at a specified start and stop time? The functionality I need is:

1) take file (example.mp3)
2) take start and stop times (hh:mm:ss, hh:mm:ss)
3) return new file with audio from given start and stop times

Thanks

Re: Django ORM - query help

[Jani Tiainen]

Hi,

You're not doing anything wrong. The catch is that since "Thing" can exist
without Log you will get outer join.

If you want to get along with inner join, you should turn query around and
start querying from Log model. I'm just too tired to think how it should be
done right now... =)

how to submit data in django's database

[Sophia]

Hi all,

I have a question about how to enter data in django's database. I have the 
following Template, in which ' E ' is a variable that get the string:



This is my models.py in which I have a class named 'Company' and I want 
this variable 'E' be saved in 'Subject' :

class Company(models.Model):
Subject = models.CharField(max_length=30)
start_time = models.DateTimeField()
end_time = models.DateTimeField()

def __unicode__(self):
return self.Subject

Then in views.py I wrote something like this to save the variable in 
Subject field, it's incomplete, and I want you to help me about it :

def Text_Box(request):
T = request.GET.get(E,' ')
if T:
   # I don't know how to make an object of class 'Company' so then I 
save ' T ' in Company.Subject
 else:
return render_to_response("Base.html") # Base.html is my basic 
template file

I would really appreciate if you help me with it.
Thanks in advance.

Sophia

Django ORM - query help

[David]

class Log(models.Model):
thing = models.ForeignKey(Thing)
context = models.CharField(max_length=255)
action = models.CharField(max_length=255)
modifier = models.ForeignKey(User, limit_choices_to={'groups__in':
[2]})
modified_on = models.DateTimeField(auto_now=True)

class Thing(models.Model):
prefix = models.CharField(max_length=50,choices=PREFIXES,
blank=True)
first_name = models.CharField(max_length=255)
last_name = models.CharField(max_length=255)

Hello,

Given the above models, how can I achieve the following results:

A unique "Thing" instance along with the last (in terms of date)
modified_on instance (ideally with access to the other related fields
such as modifier) from the "Log" model? I have tried using .annotate
but it seems to result in a very ugly left outer join which makes me
think I must be doing something wrong.

Such as:

last_modified =
Thing.objects.select_related().annotate(deletion_date=Max('log__modified_on')).order_by('-
deletion_date')

Any assistance would be much appreciated.

Re: Quick tutorial question

[Mark Phillips]

Check the bottom of tutorial #1 -

Wait a minute.  is, utterly, an unhelpful representation
of this object. Let's fix that by editing the polls model (in the
polls/models.py file) and adding a
__unicode__()
method
to both Poll and Choice:

class Poll(models.Model):
# ...
def __unicode__(self):
return self.question
class Choice(models.Model):
# ...
def __unicode__(self):
return self.choice

It's important to add
__unicode__()
methods
to your models, not only for your own sanity when dealing with the
interactive prompt, but also because objects' representations are used
throughout Django's automatically-generated admin.

Quick tutorial question

[oneroler]

I'm working through the tutorial and was setting up the admin site for the 
polls app.  I noticed in the "Select Poll to Change" section that it was 
showing "poll object" rather than "what's up" or the question associated 
with the poll.  Same is true on the Choice area of admin, the dropdown for 
polls just shows a number of poll objects rather than the names.  I can't

from polls.models import Poll, Choice

Need help with Django formsets

[BeriK]

I'm making a survey site with django. I am pretty newbie with django
so I apologize in advance if I can not explain well. My question
focuses on the following models:

class SurveyType(models.Model):

name = models.CharField(max_length=200)

def __unicode__(self):
return self.name

class Question(models.Model):

ANSWERTYPE_CHOICES = (
(u'T', u'Text'),
(u'R', u'Range'),
(u'M', u'Media'),
)

question = models.CharField(max_length=200)

surveytype = models.ForeignKey(SurveyType)

answertype = models.CharField(max_length=1,
choices=ANSWERTYPE_CHOICES)

order = models.IntegerField(default=0)

def __unicode__(self):
return self.question


class Survey(models.Model):

course = models.ForeignKey(Course)

surveytype = models.ForeignKey(SurveyType)

def __unicode__(self):
return u"%s %s" % (self.course, self.surveytype)

class Answer(models.Model):

answer = models.CharField(max_length=400)

survey = models.ForeignKey(Survey)

question = models.ForeignKey(Question)

def __unicode__(self):
return self.answer


Django receives survey id. With the survey id it gets the surveytype
and shows questions that must be displayed.

def survey(request, survey_id):
survey_data = get_object_or_404(Survey, pk=survey_id)
survey_type = survey_data.surveytype
questions = Question.objects.all().filter(surveytype =
survey_type).order_by('order')


I have read the django documentation about formsets but I don't
understand what I have to write in forms.py, so I can't call the form
in views.py to render de form in the template that shows the questions
and write the answers in the answer model.

Thanks in advance and sorry for my english.

Variations on a table for different clients?

[Derek]

Does anyone have any experience with working with systems where different
clients all need variations on the same basic table; there might be, say,
10 common fields, but each client will need an additional 2 or 3 that are
specific to them (and, possibly, not need 1 or 2 of the common ones).

What approaches or practices will help streamline work and prevent such
variations from becoming a headache to maintain?  (And yes, its likely to
be more than one table that will require these variations).

Thanks
Derek

Hi,

to test Django using django manage.py, tests have to be in:
- - a file called tests.py in the app dir.
- - in the models.py file

I haven't tried with the DjangoTestSuiteRunner, but this is what I did
in a non Django module for testing. This is an excerpt from a test:

suite = unittest.TestSuite()
suite.addTests(doctest.DocTestSuite(ad))
suite.addTest(unittest.makeSuite(TestAdFunctions))

ad is the module I wanted to test (file is ad.py) and TestAdFunctions is derived
from unittest.TestCase.

Do you have an __init__.py?
If you put your test in a tests.py file, does it then work?

Regards,
Benedict

Re: Filtering ForeignKey Drop Down in Admin Interface

[Святослав Б]

Hi!

Override ModelAdmin get_form() method and filter your field.

class MyAdmin(admin.ModelAdmin):
def get_form(self, request, obj=None, **kwargs):
form = super(MyAdmin,self).get_form(request, obj,**kwargs)
form.base_fields['field'].queryset =
form.base_fields['field'].queryset.filter(user=request.user)
return form
