Re: timeit module put my app into infinite loop

[K*K]

Thank you, Bruno.

My program running ok with your guide.

My goal is to compare the ORM performance of Django and
TurboGears(SQLObject or SQLAlchemy).

So write the test scripts.

To process 1000 times data, django's test result is below:

Insert Speed: 0.766191005707
Select Speed: 0.027615070343
Update Speed: 3.05239295959
Drop Speed: 0.941470146179

It looks not very good, my codes need more optimization.

PS: I don't want to delete the p1 from database, just want to unset
the variable. So use the del p1 and not p1.delete()

Right. I can see how this is useful for creating a generic form template.

In that case, I'd probably write a custom tag to do the job, probably
something along the line of:

{% if_widget_select field %}

This is something similar that I had done previously:

from djblets.util.decorators import blocktag

register = Library()

@register.tag
@blocktag
def if_is_select_field(context, nodelist, field):
if isinstance(field, forms.MultipleChoiceField):
return nodelist.render(context)
else:
return ''

You can find djblets tag helpers here: http://www.chipx86.com/blog/?p=245

Cheers,
Ronny

Re: i18n in templates and views

[J]

This is perfect! Thank you Malcolm.

One more question--simpler this time:

How would I include the "date" field from the first model ("Post") in
the queryset created from "PostI18N", using something similar to:

queryset =
PostI18N.objects.filter(lang=get_language()).order_by('post__date')

Would that date field already be included? How would I access it from
the template?

Thanks,
J

This surely doesn't have anything to do with your URLconf - the
randomness has to be inserted in your view, since (I am presuming) you
would like the same URL to show a different quote on separate loads.

I do the same thing with books on holdenweb.com (though in fact this is
done in a context manager, not in the view itself, since it is common to
all pages).

Is your problem the mechanics of *making* the random choice, or are you
uncertain how to get it into your output?

 Steve

Organizing apps without using projects

[Brent Hagany]

My apologies if this has been brought up before on this group - my
searching did not turn up anything, but my search skills are
notoriously suspect.

I have been reorganizing my code so that it does not depend on the
project (mostly with success) after watching James Bennet's talk at
Djangocon about reusable apps.  I've chosen to follow the model James
talks about with respect to Ellington - that is, I have a bunch of
interdependent apps that are all under the umbrella of one python
module.  Right now, I actually have one umbrella "app", with a bunch
of proper apps underneath it, so that I only have to put the umbrella
module in INSTALLED_APPS, rather than each sub-app.  I'm not quite
sure if that's the best way to do this, but more on that in a bit.

The only things I don't have working again are my unit tests, and I'd
like to get some feedback on what would be the best way to get them to
work with this sort of setup.  The problem is that my tests and models
are currently in umbrella.app.tests/models, but the test runner
expects them to be in umbrella.tests/models.  Here are a few ways to
get this done, that I can see:

1. Move all my models and tests from umbrella.app to umbrella.  This
almost completely undoes the benefits of breaking the application into
small apps.

2. Rather than just putting umbrella in INSTALLED_APPS, put every
umbrella.app in.  This just seems silly to me, since these apps are
too interdependent to be very useful apart from each other.

3. Write a new test runner that looks in the correct places.  This
makes it harder than just "manage.py test" for other people to test
the app themselves.

If you've dealt with this kind of thing before, or have a good idea/
recommendation, please let me know.  I doubt that there is a
completely satisfactory solution (to me), but I'd like some opinions
on what sucks less.

Thanks,
Brent

Hi Steve -

Yeah i know the randomization needs to be in the view and then pushed
back to the template.  How would I call the view on each page in the
website?

I just did exactly this, and found that what works best is not just to  
add an input field to the form template, but to actually subclass the  
builtin CommentForm and add the field there. That way the field will  
be a part of the form no matter how and where you use it, and will  
remain in the 'cleaned data' dictionary when the form is validated.  
Subclass the builtin form, add the field, and then do:

from django.contrib import comments

def my_get_form():
 return MyCommentForm

comments.get_form = my_get_form

Signals are beautiful! I made Commenter (email field) and  
CommentNotification (commenter and entry foreign keys) models, and did  
this:

def make_notification(sender, comment, request, **kwargs):
 notify = request.POST.get("notify", None)
 email = request.POST.get("email", None)
 if notify and email:
 commenter, created = Commenter.get_or_create(email=email)
 notification, created =  
CommentNotification.get_or_create(commenter=commenter,  
entry=comment.content_object)

def notify_commenters(sender, comment, request, **kwargs):
 notifications =  
CommentNotification 
.objects.select_related().filter(entry=comment.content_object)
 if notifications:
 for n in notifications:
 msg = render_to_string('comments/email.txt', 
{'comment':comment,'notification':n})
 send_mail("There's a new comment!",msg,"[EMAIL PROTECTED] 
",recipient_list=[n.commenter.email],fail_silently=True)

comment_was_posted.connect(make_notification)
comment_was_posted.connect(notify_commenters)

The email contains a link with a security hash which they can use to  
un-register themselves for that particular blog entry.

I only just wrote all this and haven't tested it yet, but the basic  
principle ought to be sound...

Hope that helps,
Eric

Hi.  I have a project with one template only.  I am trying to get a

pre_delete, post_delete signals for contrib.contenttypes

[Andrew Fong]

Let's say you have model A with a foreign key link to model B -- that
is,  A depends on B. If you delete model B, then model A is removed as
well. You will also get two sets of deletion signals. One for A and
one for B.

When using a generic relation however, the signals for A are not sent
when you delete B. However, model A itself is still removed from the
database.

Any opinions about adding such a deletion signal for A?

Problem generating permalink for date-based view

[Brandon Taylor]

Hi everyone,

I'm using the generic date-based views.

Here's a snippet of my "Entry" model for a blog:

#models.py
pub_date = models.DateTimeField(auto_now_add=True)

@models.permalink
def get_month_entries(self):
return ('archive_month', (), {
'year' : self.pub_date.strftime("%Y"),
'month' : self.pub_date.strftime("%b").lower()
})


Here are my URL patterns:

#urls.py
url(r'^blog/(?P\d{4})/(?P\w{3})/$', 'archive_month',
entry_info_dict, name='archive_month')


archive_month returns me a date_list object, which I'm iterating over
and displaying months:

{% for date in date_list %}

{{ date|date:"F" }}

{% endfor %}


But, when I view my template, only the year is in the link:

http://localhost/blog/2008/

instead of

http://localhost/blog/2008/oct/

Can someone see what I'm doing wrong?

TIA,
Brandon

Re: Conditions in templates

[hasan_aljudy]

You can't really do it that easily with the default django template
language,
bu check out Jinnja2,
http://jinja.pocoo.org/2/documentation/
it's an alternative template language/system that can be plugged into
django.

it offers what you need and more useful features that save you time
and make you more productive.
its syntax is very similar to django (infact it was inspired by
django)

Yes. Should certainly be in 1.1. Probably land in a few weeks.

Specify that syncdb not create a table for a Model

[Ed Anuff]

I reviewed this thread from March on whether it's possible to mark a
Model so that syncdb doesn't create the table for specific Models and
was wondering if there are any updates to this:

http://groups.google.com/group/django-users/browse_thread/thread/ba928abb39db2e31?tvc=2

I'm integrating with a legacy database schema which uses the single-
table-inheritance pattern for storing several different classes in a
single table with a single column discriminator, and since Django
doesn't support that, thought next best thing would be to create a set
of Models which used the same table, which works, but I also want to
eventually use syncdb to create the database and want it to be able to
handle the situation correctly.  Still not possible?  Something I can
easily hack Model to do myself?  On the roadmap?

There's a currently undocumented function in django.utils.translation
called get_language() that you can use to return the currently active
locale. So something like

PostI18N.objects.filter(lang=get_language())

will filter out only the articles matching the current language. You can
safely use that function, even though I said it was undocumented. That's
because it will be documented inside the next 48 hours. I'm currently
rewriting the i18n documentation and just made a note to include that (I
hadn't realised until just now that we had left it out).

Sorting is generally best done in the view. Even better, sorting can be
done by the database at selection time. Modifying the above queryset,
you could write

PostI18N.objects.filter(lang=get_language()).order_by('post__date')

Generic views can handle anything you can create as a queryset. However,
the above queryset actually depends on some information that is not
available until the view is active (you can't compute it once). This is
because the results of get_language() depend on the locale. So you would
need to wrap things up like this:

def my_view(request, ):
   qs = PostI18N... # <-- as above
   return archive_index(qs, )

That way, the get_language() call is executed each time in the right
environment.

Malcolm

Write a template tag that does exactly that. Django ships with a
relatively minimal, but fairly complete set of tags, and then encourages
you to write your own (or use other people's) to do any extra stuff you
might like.

That pattern should be

As it is you are passing the null string as your "year" view argument:

No, you can't do that. The get_absolute_url method on the model is
entirely replaced. The former version is an ex-parrot, so to speak
(okay, I'm implicitly ruling out bytecode hacks to get at it, but
hopefully, so are you).

This does hint that you're using the wrong shovel to hammer in your
screws, however. You've said that you want to change that URL, always.
Hence it's in ABSOLUTE_URL_OVERRIDES. Later you are effectively saying
"no, just joking... I don't want it overridden all the time". If it's
only meant to be changed sometimes, the ABSOLUTE_URL_OVERRIDES is not
the right tool for the job.

What is the real problem you are trying to solve?

Double encoded slash in path_info removed when using apache/wsgi

[Merrick]

I need urls that contain other urls within them i.e.

http://mydomain.com/find/http%3A%2F%2Fwww.wired.com%2F%2F

I am using Apache 2.2.3-4, mod_wsgi 2.0-1 and have
"AllowEncodedSlashes On" within my virtualhost conf file, this setting
allows me to have encoded slashes in the path_info without having
apache return a fake 404.

My views.py includes:

def find(request, url):
import urllib
url = urllib.unquote_plus(url)
form = FindForm({'url': url,})
return render_to_response('find.html', { 'form': form, 'request':
request })


The template find.html includes a line {{ request.path_info }} to
print out the path_info.

Firefox shows the second encoded forward slash is removed when calling
this url:
http://mydomain.com/find/http%3A%2F%2Fwww.wired.com%2F%2F
 prints out:
/find/http:/www.wired.com/

The django test client prints out the second forward slash

>>> ./manage.py
>>> from django.test.client import Client
>>> c = Client()
>>> response = c.get('/bookmarklet/http:%2F%2Fwww.wired.com%2F%2F')
>>> response.content
'/find/http://www.wired.com//'

I did not include anything about my regular expression in urls.py up
until this point because it is not related to this problem from what I
can tell, but in case you are wondering I was trying to capture the
url after find/ - my regex looks like this r'^find/(?P(.*))$'

Thanks for looking at this,

Merrick

generic.date_based.archive_year throws "invalid literal for int() with base 10: ''

[Brandon Taylor]

Hi everyone,

Here is my code:

entry_info_dict = {
'queryset' : Entry.live.all(),
'date_field' : 'pub_date',
'allow_future' : True
}

urlpatterns = patterns('django.views.generic.date_based',
url(r'^blog/(?P)\d{4}/$', 'archive_year', entry_info_dict,
name='archive_year'),
)

So, when I hit: http://localhost:8000/blog/2008/sep/

I get: invalid literal for int() with base 10: ''


I know these values are valid, as I have an Entry in the database and
my URL param is populated form the DB. I have also visually verified
that the values are correct. What can I possibly be doing wrong here?

I'm using Aptana with PyDev, and have stepped through the debugger for
the archive_year function, and I'm just not seeing what the problem
is. Anyone else seeing something similar?

TIA,
Brandon

i18n in templates and views

[J]

Hi everyone,

I'm working on a bilingual website in django for which the visitor has
the option of choosing which language he/she prefers. All the interface,
as well as the content, will be available in Spanish and English. The
interface is set up to be handled by gettext and django's has excellent
support for that.

I'm having a hard time right now with the bilingual "posts" system,
which is for contributors to add articles in different categories. Each
post will have two items for it, one in each language.

The way I've got it set up in the models is:

##
# The parent of all the posts,
# only one item per post in here
##
class Post(models.Model):
referencetitle = models.CharField(max_length=30)
date = models.DateTimeField('Date')

##
# language content for each post
# there will be two items per post in here, one for each language
##
class PostI18N(models.Model):
post = models.ForeignKey(Post)
slug = models.SlugField(
'Slug',
help_text='Automatically built from the title.'
)
title = models.CharField('Title', max_length=30)
body = models.TextField('Body Text')
lang = models.CharField(max_length = 5, choices = settings.LANGUAGES)



How do it do this in _views _so that I only get the "PostI18N" items
that are in the current language chosen by the users, and how do I
iterate through both of these models at the same time in templates so
that I can access the Date field from the related table ("Post") to sort
them, but display the main content fields from "PostI18N".

I'm initially attempting to display this data using generic views
(django.views.generic.date_based.archive_index). Do you think these
generic views can handle something like this? If not, how would I write
an equivalent custom view?

Thanks for your help with this,
J

"django's mysql performance" doesn't really makes sense. What you're
testing with your code is the combined perfs of
- Django's orm
- Python's MySQLdb connector
- your version of MySQL

(not to talk about your system etc...)

Ok, the distinction is a bit pedantic, but it might be better to make
things clear. If what you want to test is django's ORM itself, you
should also code doing the same operation using only the MySQLdb
connector, timeit *under similar conditions* (system load etc), and
compare both results to know what comes from the ORM itself.

Pedantic again, but what you're doing is  benchmarking - "profiling"
is something quite different.

Can M2M be one-way?

[Dylan Reinhardt]

Is there any way to make Django ManyToManyField objects not be bi-
directional?

I have a Product object with a self-referencing M2M field.  I want
each Product to maintain its *own* list of related products... I do
not want Products affecting each other's lists.  When A points to B, I
don't necessarily want B pointing to A.

I can appreciate how bi-directionality is the right answer for most
cases... but is there any way to suppress this behavior?

I'm probably a bit tired, but I don't see how the below snippet could
cause an infinite loop - unless you did something very wrong in the
parts of the code that are called but you didn't post.

Err... Wait... This is what asked for, didn't you ? (cf below...)

You don't need the global statement here since you're not rebinding
loop_range. FWIW, you could declare it as a local variable anyway


> insert_timer = timeit.Timer("benchmark_insert()", "from
> testDjango.bench import benchmark_insert")
> insert_timer.repeat(loop_range)
> insert_speed = insert_timer.timeit()

I suspect you misread the doc for timer.repeat and timer.timeit.
Timer.timeit will already repeat the given statement quite a few times
(100 by default). Timer.repeat will call Timer.timeit x times. So
with your above code, you will first call benchmark_insert() 10 *
100 times, discard the result, then call benchmark_insert()
100 more times.

If you meant to only call Timer.timeit once and make it call
benchmark_insert only 10 times, you want :

  insert_timer = timeit.Timer(
  "benchmark_insert()",
  "from testDjango.bench import benchmark_insert"
  )
  insert_speed = insert_timer.timeit(loop_range)


> def benchmark_insert():
> p1 = Django(foobar='Test foo',)
> p1.save()
> del p1

I think you meant p1.delete().  'del p1' unbind the name p1 in the
current namespace - which is pretty useless here FWIW -, but won't
remove anything from your database.

Re: custom field problem w/Django v1.0

[Siemster]

Not being a Python guru by any stretch of the imagination, I have no
idea if the following is a proper way to do it, but adding:
"
def __unicode__(self):
return u'MAC Address'
"
to the MacAddressField class definition does work. For my purposes. As
long as I'm o.k. with the label always being 'MAC Address' no matter
where I use it.

It would be nice to figure out the preferred way of implementing
custom fields. The documentation, while nice, seems to be incomplete
in this area... Google hasn't been very helpful in searching for
examples either.

Anybody out there know of one or more good examples of implementing
and using these beasts?

cl is set via a template tag.  You may be interested in this ticket:

Remove the '/basic' part from your PYTHONPATH. The PYTHONPATH should
point to directories *containing* packages, not to the packages
themselves.

Re: auth.login problems in Django 1.0

[Cold]

I got exactly the same problem, with the nearly the same code.
I used pdb and check that login(request, user) is well called.
But in the next view, in my template i do a {% user.is_authenticated
%},
and it seams that the user is not logged in.
Someone have an idee ? bug or wrong session configuration ?

Regards

Vincent

I get an error (in red font):
Error: No module named basic

the blog folder is in: /home/myusername/local/basic

my PYTHONPATH is:  /home/myusername/local/basic:

my settings.py INSTALLED_APPS looks like this:INSTALLED_APPS =
(
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.markup',
'projects.polls',

Re: re-direction after login successfully

The setting LOGIN_REDIRECT_URL will allow you to change the default.

Conditions in templates

[Kasper Grubbe]

Hi again.

In my application i need to know if a number in a list is bigger than
1000 or got 4 letters in it. I have to do this in my template.

This is my code in the template:

{% for menuitem in availList %}
  {% if menuitem|length > 3 %}
{{ menuitem }}
  {% else %}
{{ menuitem }}
  {% endif %}
{% endfor %}


Is there any thing i can do to achieve this?

Date-based generic views and 404 errors

[Brandon Taylor]

Hi everyone,

I'm following along with the Blog example in the Practical Django
Projects book. Here are my URLs:

entry_info_dict = {
'queryset' : Entry.live.all(),
'date_field' : 'pub_date'
}

urlpatterns = patterns('django.views.generic.date_based',
url(r'^blog/$', 'archive_index', entry_info_dict, name='blog'),
url(r'^blog/(?P)\d{4}/$', 'archive_year', entry_info_dict,
name='archive_year'),
url(r'^blog/(?P)\d{4}/(?P\w{3})/$', 'archive_month',
entry_info_dict, name='archive_month'),
url(r'^blog/(?P)\d{4}/(?P)\w{3}/(?P)\d{2}/$',
'archive_day', entry_info_dict, name='archive_day'),
url(r'^blog/(?P\d{4})/(?P\w{3})/(?P\d{2})/(?
P[-\w]+)/$', 'object_detail', entry_info_dict,
name='entry_detail'),
)

I can view the archive index, and the entry detail, but archive_year,
archive_month and archive_day all return 404 error pages. Can someone
please point out what I'm doing wrong?

TIA,
Brandon

This is covered in the official docs, the given example works
perfectly:

http://docs.djangoproject.com/en/dev/howto/outputting-csv/#howto-outputting-csv

And if that's really your SQL query you can easily get away with a
Queryset instead of doing it manually.

Re: seeking help in model design...

hey david,

ah - thanks so much!  i made two mistakes:  using abstract - and
linking to self rather than to Node.  i'm guessing here - butu are two

table?

anyway, i'm back up and running on my fledgling project - thanks to
you!  :-)

html inserted into csv file

[Bobby Roberts]

HI group.  I'm using the python csv writer to drop a csv file
available for download/opening when a button is clicked on my site.
The code is shown here

  myselchecks=selchecks
  sql="select * from inquiries where inquiry_id = (%s)"
%myselchecks

  ctx.request.write_header('Content-Type', 'text/csv')
  ctx.request.write_header('Content-Disposition','attachment;
filename=contacts.csv')
  ctx.request.write = ctx.request.write_content
  writer = csv.writer(ctx.request)
  c = ctx.request.db.cursor()
  c.execute(sql)

  writer.writerow([x[0] for x in c.description])
  writer.writerows(c.fetchall())


This code drops all selected fields into a temporary csv file named
"contact.csv" so that it can be downloaded.  However, the template
HTML is being appended after the last record in the csv file.

Is there any way to prevent this from happening?

Django Admin, Custom Views and the ChangeList object

[Brandon Taylor]

Hi everyone,

On a recent project, I was tasked with adding a workflow around a
model, which required some customization in the admin. I found that
when I did and override of a view, I no longer had access to the "cl",
or ChangeList object containing all of the objects for the view.

Filters and other built-in functions in the admin templates depend on
this object, but I haven't been able to figure out how to return this
object in my own custom views.

Can anyone shed some light as to how to create and pass in the "cl"
object list for use within custom admin views?

Kind regards,
Brandon

Re: Too many values to unpack

[mthorley]

Alright then, I found the answer to my own question. A patch for
"optgroups" was added to the ChoiceField at revision 7977. As it turns
out my custom widget breaks because it relies on the behavior of
ChoiceField before the patch. In order to fix the problem I'll have to
update my custom widget.

Thanks again to all

Re: seeking help in model design...

[David Hall]

Hi Paul,

So long as the common model is not abstract, it should work.  Also, the 
common model must be the one that contains the parent field, and it 
should link to "Node" and not "self".

Using my first example, you should be able to traverse the tree using 
Node.parent and Node.children.  Traversing the tree using Job.parent, 
Job.children, Shot.parent or Shot.children will not work.

I've implemented the first example in one of my own apps, and it does 
work!  :P

David.

Re: Too many values to unpack

[mthorley]

Thanks that helps quite a bit. I see now, it expects each item/element
in 'v' to be two-element tuple.

Does any one know if there was a change made to the format of the
choices argument for forms in django 1.0?

Re: setting a pre-selected value for the ChoiceField

[Ugandhar Reddy]

I had similar requirement i.e showing a pre-selected value in the
ChoiceField after looking into the ChoiceField django code its become
clear to me that the value of the text to be assigned to initial.

With this change country field in the Form object looks like:

country =  forms.ChoiceField(required=True, choices=arr,
label="Country", initial="TT")

Considering "TT" is the value associated with "Trindbad" text in the
"arr" list of tuples.

This might help you or others who might face this.

Re: Multiple ManyToMany relations with the same class

[Pablo Catalina]

# python manage.py validate
Error: One or more models did not validate:
concerts.concert: Accessor for m2m field 'musicans' clashes with related m2m
field 'person.concert_set'. Add a related_name argument to the definition
for 'musicans'.
concerts.concert: Accessor for m2m field 'coches' clashes with related m2m
field 'person.concert_set'. Add a related_name argument to the definition
for 'coches'.

OK.

The problems is with the order of the fields, I solve It:

Now, the problem:

models:
from django.db import models
from django.contrib.auth.models import User, UserManager


class instrumentos(models.Model):
nombre = models.CharField(max_length=10)
numero = models.PositiveSmallIntegerField(blank=True, null=True)
def __unicode__(self):
return self.nombre

class samberos(User):
objects = UserManager()
dni = models.CharField(max_length=10, blank=True, null=True)
phone = models.CharField(max_length=9, blank=True, null=True)
movil = models.CharField(max_length=9, blank=True, null=True)

class contactos(models.Model):
name = models.CharField(max_length=30)
phone = models.CharField(max_length=9, blank=True, null=True)
movil = models.CharField(max_length=9, blank=True, null=True)
mail = models.CharField(max_length=30, blank=True, null=True)
def __unicode__(self):
return self.name

class relaciones(models.Model):
sambero = models.ForeignKey(samberos)
instrumento =  models.ForeignKey(instrumentos)
def __unicode__(self):
return '%s => %s' % (self.sambero, self.instrumento)

class actuaciones(models.Model):
titulo = models.CharField(max_length=80)
fecha = models.DateTimeField()
descripcion = models.TextField()
lugar = models.CharField(max_length=200)
organizador = models.ManyToManyField(samberos)
samberos = models.ManyToManyField(relaciones, blank=True, null=True)
confirmada = models.BooleanField(default=False)
contacto = models.ManyToManyField(contactos)
coches = models.ManyToManyField(samberos, blank=True, null=True,
related_name='actuaciones_coches')
def __unicode__(self):
return self.titulo

And the solution is to change the order of the fields:

class actuaciones(models.Model):
titulo = models.CharField(max_length=80)
fecha = models.DateTimeField()
descripcion = models.TextField()
lugar = models.CharField(max_length=200)
organizador = models.ManyToManyField(samberos)
coches = models.ManyToManyField(samberos, blank=True, null=True,
related_name='actuaciones_coches')
samberos = models.ManyToManyField(relaciones, blank=True, null=True)
confirmada = models.BooleanField(default=False)
contacto = models.ManyToManyField(contactos)
def __unicode__(self):
return self.titulo

Implementing "Friends application" using many-to-many relationship on self

[NEX]

Hi everybody,
I was trying to add friend network feature to my site. But I have to
use User model from django.contrib.auth .
I tried extending User model and added a many-to-many field in the
extended model. But then I was unable to retrieve all the
connections(friends) using the "_set" feature.
Please suggest some way I can implement the same.
Thanx

The issue here is that the for statement expects a *sequence* of
two-element tuples to iterate over and, for whatever reason, it's only
getting a single tuple. Hence the error message.

I hope this gives you a start on finding out what's actually wrong ...

 Steve

Re: seeking help in model design...

[paul]

hi david,

many thanks for your help there. i initially tried the inheritance
method - buut found that my tree traversal broke when trying to
traverse a tree made of different types (ie, Node & Jobs).  maybe i
did something wrong?  ie, should i be able to make a tree from those
two types if derived from a common model.  or is each derived model
incompatible with each other?

cheers,

paul

timeit module put my app into infinite loop

[K*K]

Hi, all

I'm writing a program to test django's mysql performance, use timeit
to profile. But it make my app into infinite loop. always write data
into database.

How can I resolve it ?

The source code like below:


import timeit

from django.shortcuts import render_to_response
from testDjango.benchmark.models import Django

loop_range = 10

def benchmark(request):
global loop_range

insert_timer = timeit.Timer("benchmark_insert()", "from
testDjango.bench import benchmark_insert")
insert_timer.repeat(loop_range)
insert_speed = insert_timer.timeit()

return render_to_response('benchmark.html', locals())

def benchmark_insert():
p1 = Django(foobar='Test foo',)
p1.save()
del p1

Too many values to unpack

[mthorley]

I just upgraded to django 1.0 and started getting this error. I was
already using newforms and am quite surprised and dumbfounded by the
errror. Generally this error would be caused by a missing comma in a
tuple, but that appears to not be my case.

I added some print statements (to django/forms/fields.py) and even
over-wrote the variable in question to try and isolate the problem but
have had no success.

Below is a snip of the code in question, with my added debugging
statements. Note that even when I override "v" with a tuple containing
two string, I still get the error.

That almost makes me think something is broken with my python install,
however when I execute a similar statement from the python shell, it
works fine, and when I run the server with a different installation of
python I still get the error.

Below the code snip is the output I get in my terminal when the below
code runs. At the bottom of this post is a complete trace back of the
error.

I'm sure now that I am over looking something very obvious, and would
be very appreciate to any one who can point it out to me.

Thanks

I'm only hosting personal stuff there, so not much traffic...
As Jarek said, perhaps it's better to go with dedicated hosting if you  
plan to have loads of traffic.

But you can always ask the folks at djangohosting what they think of  
it directly, they are quite nice and answer quickly.

simple bookkeeping package

[copelco]

Hello!

Just thought I'd ping the list to announce a simple Django bookkeeping
package we've been working on here at Caktus.  minibooks helps you
manage invoicing, receipts, bank and credit card statement
reconciliation, project reports, etc.  The project is is free and open
source!  It is still in a very early stage (we add to it as need be),
but we've been using it as our company portal for a few months now.

Check it out!

Extend contrib.comments?

[fitzage]

I want to add one additional piece of data to the comment form.
Basically a checkbox that says whether or not the commenter wants to
be notified of followup comments.

I know how to add the checkbox. I just created a comments/form.html
template and added the checkbox to it. I know that the data is getting
passed correctly.

Now how do I grab that on the backend without having to modify the
comment app directly? There is probably a simple, django-standard way
to do this, but I'm at a loss. I already have a function that emails
admin users when a comment is posted, but I'm not sure I understand it
well enough to piggy-back off of that, and I'm not even sure that I
can.

What version of Django are you running?  These two patterns are from
different Django versions.  The first, with the include of
'django.contrib.admin.urls' was the old one -- that file does not exist in
Django 1.0.  The 2nd pattern, referring to 'admin.site.root', is what should
be used for Django 1.0.

If you are actually running 1.0 the old pattern would have produced a "No
module named urls" error since django/contrib/admin/urls.py no longer
exists.  So I am confused as to how commenting out the 2nd version, which is
the one that is correct for 1.0, would have fixed that problem.

Re: Django Admin - Does not see templates, images or templates.

[NoviceSortOf]

Yes I restarted, but I also noticed in urls.py

2 distinct suggested admin url patterns...

(r'^admin/', include('django.contrib.admin.urls')),
# (r'^admin/(.*)', admin.site.root),

Commenting out the second entry seems to correct
the admin_urls problem.

Why does the documentation suggest
 (r'^admin/(.*)', admin.site.root)?

Re: Django + tiny_mce

[Brian Jones]

I fixed it. Once I knew that the APPEND_SLASH was kicking in *because*
the url couldn't be found, I just moved the relevant line in my
urlconf to be the first one in my 'urlpatterns' tuple, and from there
I believe everything in the example in the book "just worked". It is
unbelievably annoying that I had to spend so many hours to get it to
work, but I thank you for your clue!

If all you're doing is serving those files, don't put them in the  
database. There are more efficient ways to do that, even if you  
require authentication or other special handling.

If you're doing something more interesting with them, then two  
approaches spring to mind. You could look into writing a custom  
Storage implementation to save them into the database (see 
http://docs.djangoproject.com/en/dev/ref/files/storage/) 
, or you could just add a FileField to your form instead of your  
model, and in the form's save method, read the file contents into a  
TextField on your model.

I wouldn't go into production with shared hosting if you expect at  
least moderate popularity. You'd end up paying more than dedicated  
hosting would cost you (eg. at hetzner.de).

Sorry for the mix up. The log messages I pasted in are from yet

Re: dynamic associations?

[Alex G]

Ah, it works for me too, except in the case of relations.

Essentially, it all comes down to one line of code; given an instance
model, a method as a string, and a secondary instance of a model,
something like:

getattr(model_instance, attr_name).add(model_to_add)

So, something like:

>>> from project.models import MyModel
>>> my_model = MyModel(attr1 = 'value')
>>> my_model.attr1   # works fine, of course
'value'
>>> getattr(my_model, 'attr1') # also works, no surprises yet
'value'
>>> getattr(my_model, 'some_relation_or_fk') # but...
Traceback (most recent call last):
  File "", line 1, in 
  File "/Library/Python/2.5/site-packages/django/db/models/fields/
related.py", line 235, in __get__
raise self.field.rel.to.DoesNotExist
DoesNotExist

So I can't assign it to a variable (in order to set it)...  Any ideas?

-Alex.

You probably don't want to change that.  It's the APPEND_SLASH setting that
is doing this and the fact that it is coming into play means there's a
problem elsewhere: namely the incoming url for tiny_mce.js is not being
matched by anything in your urlconf.  This one in particular is missing the
tiny_mce/ prefix that your static server urlpattern is expecting.  Is this
one coming in from your manual testing or from an actual page request?  The
change_form template fragment you show does have the /tiny_mce/ prefix so
I'm puzzled how it would be missing from that page request.

I don't have time to comb through all of what you provided, but the problem
you want to solve is making the initial request coming in match something
that will be served by your static server configuration, not turning off
APPEND_SLASH.  Solve the first problem and you won't see the 2nd behavior.

Django + tiny_mce

[Brian K. Jones]

This scenario has been brought up before, but I'm having a problem
that hasn't yet been reported. I was unable to reply to the whole list
in the google groups interface - only "Reply to author" was available.
Here's the thread for reference:
http://groups.google.com/group/django-users/browse_thread/thread/c1f111291e1e45f1/ce9f9f28da72388a?lnk=gst=development+server+slash+404#

In short, I'm going through the Practical Django Projects book, trying
to get the tiny_mce configuration on pages 24 and 25 to work, and I'm
having zero luck. I'm using Django 1.0, and the development server, on
a mac, running Leopard.

It looks like I have the urls.py and change_form.html set up properly,
but the problem is that whether I try to load the admin page, or I try
to access tiny_mce.js directly in my browser from the django
development server, the dev server is redirecting me (302) to the same
path I ask for, except with a "/" at the end. So I get this in my
log:

[07/Oct/2008 08:48:31] "GET /tiny_mce.js HTTP/1.1" 302 0
[07/Oct/2008 08:48:31] "GET /tiny_mce.js/ HTTP/1.1" 404 1708

Of course, that's no good, but I have no idea where the magical
setting is to change that. I've tried removing/replacing trailing
slashes all over the place, to no avail, so I imagine this is
something in the settings.py file that's hurting me. Here are my
files:

urls.py:

from django.conf.urls.defaults import *

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
# Example:
# (r'^cms/', include('cms.foo.urls')),

# Uncomment the admin/doc line below and add
'django.contrib.admindocs'
# to INSTALLED_APPS to enable admin documentation:
 (r'^admin/doc/', include('django.contrib.admindocs.urls')),

# Uncomment the next line to enable the admin:
 (r'^admin/(.*)', admin.site.root),
 (r'', include('django.contrib.flatpages.urls')),
 (r'^tiny_mce/(?P.*)$', 'django.views.static.serve',

AFAIK, this adds attributes to widget output. Using these attributes

Where do custom fields go?

[Penguin]

Hi Guys,

I've been playing with custom fields, but I'm not sure where the
python script containing the custom field definition goes? In the
project directory? In a new application? I have searched high and low,
but no docs seem to cover this.
Any help would be appreciated.

Xiao

Did you restart Apache after making the changes? The "sometimes it loads OK
and sometimes it doesn't" problem usually means you've got some Apache
processes running old code and some running new.

I can recommend djangohosting (http://djangohosting.ch), at least if  
you're looking for a host in europe...
It doesn't seem like you do, but I thought I should mention it anyway...

It's great for personal stuff, didn't do something big there (60MB

Storage of files in database

[Mariana Romão]

Hi,
I'm new in the group and in the use of Dajngo too.
I'm developing an application that needs storage files ".py" in database
(and maybe other types of files). I thought Django did this "automatically"
when I define the field in the model as FileField, but I realized that what
does is put in database a column as a varchar.

What I need do for that the database storage the file? Create other table or
other column manually?

(I'm sorry for a bad english).
Thanks.

I have two vps's from Linode, they're a lot like Slicehost but you get
more bang for the buck. For example, for $20 you get 256 at Slicehost,
but Linode gives you 320 MB. They also give you 2 GB more space. They
both have similar hardware (quad core servers, 64-bit). The "slices"
are 32-bit, but you can go with 64-bit if you want to. That's one of
the reasons why I switched.

Access a model's original get_absolute_url

[Erik Allik]

Hi everybody,

I need a way to access a model's original get_absolute_url after the  
ABSOLUTE_URL_OVERRIDES settings has taken effect. Currently I've  
patched Django for this need so it will always alias the existing  
get_absolute_url method as old_get_absolute_url when it overrides that  
method, but patching stuff is ugly and poses deployment/reusability/ 
upgradability issues, so I'm thinking maybe there's a hook or a signal  
that I could use to achieve the same effect.

Any hints will be appreciated!

Erik

The admin page though still loads rough, sometimes

Re: seeking help in model design...

[David Hall]

Hi Paul,

You've got a couple of options for this.  The first uses inheritance:

class Node(models.Model):
 parent = models.ForeignKey("Node", blank=True, null=True,
 related_name="children")

class Job(Node):
 pass

class Shot(Node):
 pass

The second uses generic foreign keys:

class Job(models.Model):
 parent_type = models.ForeignKey("contenttypes.ContentType")
 parent_id = models.PositiveIntegerField(db_index=True)
 parent = GenerticForeignKey("parent_type", "parent_id")

class Shot(models.Model):
 parent_type = models.ForeignKey("contenttypes.ContentType")
 parent_id = models.PositiveIntegerField(db_index=True)
 parent = GenerticForeignKey("parent_type", "parent_id")

Personally, I'd go with the first, as it will integrate better with the 
Djano admin application.  To traverse the tree, use the Node model. 
Once you have got to your required location in the tree, use node.job or 
node.shot to get the rest of the information.

David.

Filter horizontal question

[Donn]

Hi,
After spending many (many) days on my own CRUD system I am *really* seeing the 
beauty of the Django Admin system! 

A few quick questions -- regarding Many to many field and filter_horizontal : 
1. Assuming I have thousands of records, call them books, does that interface 
provide paging?
2. If so, can one control the number of records before paging cuts-in?
3. If not, how could I go about paging them myself?

Hope someone can help,
\d

[laspal]

ok I can use cStringIO for it but my real problem is how to attach
file in emailmessage??

response = HttpResponse(mimetype='application/pdf')
response['Content-Disposition'] = 'attachment;
filename=report1.pdf'
buffer = StringIO()
p = canvas.Canvas(buffer)
pdf = buffer.getvalue()
buffer.close()
response.write(pdf)
-
attach = pdf
mail = EmailMessage(subject, message, sender,[send_to])
mail.attach(attach.name, attach.read(), attach.content_type)
mail.send()

this will give me error saying object has no attribute 'name'.

Thanks.

First point : if your computation happens to be that "intensive", you
don't want to call it 'in process'. It just won't scale. So you do
have to use separate processes - possibly on different machines.

Second point : if you computation only depends on it's inputs (which
you said was the case), then you just don't have to worry about
database access - this will still be handled by your Django app. All
you need is a way to invoke the computation process with appropriate
params, and a way to know when it's done and get the result back. All
this  - inter process communication - is far from rocket science, and
has long been solved in quite a lot of ways.

Third point : all this is based on "wet finger" estimate. So it's just
worth nothing. Experience proved that we developpers can be very bad
at this kind of guessing games. IOW, until you have facts, you just
don't know.

So, to make a long story short, don't bother about this for now, and
start writing code. Start in Python, benchmark, profile, and then
you'll at least have a clue as what the real constraints are and what
the appropriate strategy might be.

Stop worrying about django, it's has nothing to do with it. And don't
worry about how Python can communicate with either another process
(whatever langage has been used to implement the program) or a C-coded
library or whatever.

>  It could very well affect my choice of language.

Python is good for prototyping, and it's the main language used in
your app. So start with Python. Once you'll have something up and
running, you'll have hard facts wrt/ time-space problem, and it will
*then* be time considering alternate solutions.  IOW : don't worry
about Django, don't worry about how Django, don't worrry about Python,
and *write this damn code*. I repeat : until you do have working code,
everrything else is just blah blah, waste of time and premature
optimization.

Re: SQL: Migration How To?

I do it like this:
# Before changes to models.py
./manage.py sqlall myapp > orig.sql
# Modify models.py
./manage.py sqlall myapp > new.sql

diff orig.sql new.sql

Now you need to now a little SQL to write the correct "ALTER TABLE ..." 
statements.
But must of the time it is not that difficult.

HTH,

Re: pdf file generated problem

[Thomas Guettler]

Hi Iaspal,

here is what I think:
 - Why do you use try:...except? You don't see the real traceback.
   If you want to add debugging information (eg. logging.error('...'))
you could do it like this:
try:

except:
logging.error('...')
raise # reraise exception

 - Why do you use HttpResponse for the canvas? You could use cStringIO or
  a tempfile.

 - Please post the traceback, if you ask for help. It shows where the 
root of the problem is.
