I did some searching on the archives (something I should have done in
the first place, D'oh!) and found threads with similar problems. The
thing is that while spawning subprocesses work fine on command line
Python programs, it looks like it's a big no-no while under mod_python
because lots of funky stuff can happen.

So it looks like I'm off to write a simple XML-RPC server that will to
handle spawning subprocesses.

 I am very new to django as well as python. how is it that ?P

If you want to do this, you will need to add a custom rendering scheme
to your form.

When you render a form using {{ form }}, you are effectively making a
call to form.as_table(). Django also provides an as_p and as_ul
variant to modify the way individual fields are rendered, which can be
accessed as {{ form.as_p }} or {{ form.as_ul }}.

To get per-field rendering like you describe, you will need to add a
custom as_ method. Look at the implementation of
django.newforms.Form.as_p() for an example implementation; adapting to
match your needs shouldn't be too hard.

Its a bit of a nifty hack. However, I was talking more about views as
a general tool - it would be nice to support them. The success that
you have had mocking them up demonstrates that it is possible, we just
need to finess them.

To my mind, the better approach here would be to have proper support
for a 'read-only' query set that disables (or doesn't have) the delete
operation, rather than significantly changing the behaviour of bulk
deletes. Read-only objects/querysets would be an essential part of any
view support in Django.

I suppose this is the sticking point. I can see how this is a neat
hack for your specific situation, but I'm not convinced its a general
problem.

Well, it is correct if you consider bulk-delete to be different to
delete. There is no bulk-save analog. Bulk delete (delete on a
queryset) is quite a different operation, that doesn't integrate with
the individual object delete.

However, the distinction obviously isn't obvious to newcomers.
Suggestions on documentation improvements are always welcome. My
initial reaction is that if there is a need for improvement, its here:

win install problem

[Carl Karsten]

I have been working on a site for a few weeks.  I have been checking my changes 
into svn, and use that to update a demo box.  the demo box runs under a 
different user, has django in a different path, and my files in a different 
path.  I did this on purpose just to make sure nothing was relying on any 
absolute paths.  I svn co the files to a mac, my sqlite based demo worked fine. 
  I tried the same thing with windows, and got errors.

Settings\test\django\ridgemoor/eventcal/templates/databrowse/object_detail.html

from IRC:
(04:48:13 PM) mattmcc: Yeah, I don't know what the deal with that is.  The 
appdir template loader seems to be skipping all the installed apps that aren't

Below is the output from my site.  I have similar problems hitting /admin.I 
am installing py and django on a 2nd win box that will be just for testing 
admin, using a 'new' site.  I'll post results of that shortly.

Note that the ticket is marked "new" rather than "closed: fixed". This
usually means that it is still an issue.

A triager might look at it and mark it "ready for checkin" rather than
"patch needs improvement", which will give it a much better chance of

I can certainly sympathize; back in my freelance days I enjoyed
writing Python and fell in love with Django after its initial release,
but PHP and Perl were paying my bills so I was pretty much stuck for a
while.

My advice to you, and to anyone else in your situation, would be to
not give up -- even if you're still mostly working with, say, PHP,
keep working with Django or other frameworks when you get the chance.
When you have some spare time, write applications you're interested in
and tell the community about them, and you never know what sorts of
opportunities might turn up. And even if you never land a professional
gig out of it, the experience will make you a better and more
well-rounded programmer, and in time that'll get you progressively
better jobs no matter what languages or tools you end up working with
it.

Also, remember that this list sees an increasing number of job offers,
and there's a spot on the wiki (the "DevelopersForHire" page) where
Django-oriented freelancers and companies can offer their services for
hire and Django-oriented employers can list jobs they want to fill.
Keep an eye on that and don't be afraid to get in touch with people
and start building up contacts in the community -- opportunities will
come to folks who put themselves in the right place at the right time
;)

Why not getting a VPS hosting (or a dedicated server) and install

needed.

PS: May be in 6-7 months there will be more offers fos django

According to
http://www.djangoproject.com/documentation/model-api/#many-to-one-relationships

``To create a recursive relationship - an object that has a many-to-
one relationship with itself - use models.ForeignKey('self').''

So basically, just take the one-to-many relationship you wanted, and
*reverse* the roles.
For example, if you had a Person object and you wanted to keep track
of the multiple Person objects who were its "employees", simply
reverse the roles.  Make each Person object keep track of its "boss"
instead.


(Hopefully that's what you were looking for; if I misunderstood the
question and you were looking for more "advanced" info, I probably
won't be much help since I'm a novice myself)

You're running against Python's short-circuit evaluation.

If "state" has a value, python uses that.  Only if the value of 
"state" evaluates as false is the 'imaging' considered.

What you need is to use the Q() object and Or them together, 
something like


Asset.objects.filter(Q(process_state=state)|Q(process_state='imaging'))

and the most  important reason that made me leave django and use php
instead is finding a REAL job.
after the freelance period, I hope to find a job in some company,
unfortunately, there is no requests for Django developers, and the
requests for a python programmer [not just for web] are extremely
low.
[I don't know the situation in the world, but thats the situation in
my place]

and again - thank you guys for commenting and helping :)

objects.filter

[[EMAIL PROTECTED]]

Okay, I am having a problem and I don't know why. I am doing an
objects.filter on a model called Asset it looks like this asset =
Asset.objects.filter(process_stage = state or 'imaging') this should
return any Asset that is equal to the state variable or 'imaging' but
it is just returning the ones that are equal to state. I have testing
this in the ipython.py command line program and it works there but not
in my script.
testing it in ipython:
from hammer.models import *
asset = Asset.objects.filter(process_stage = state or 'imaging')
asset
out: [, ]

321562 is equal to state
321654 is equal to 'imaging'

if i do a print right under Asset.objects.filter(process_stage = state
or 'imaging')
i get []

WHY?

SORRY FOR ANY GRAMMAR THAT IS WRONG.

If you can help thinks if not thinks for looking.

Re: SQL VIEWs as Django Models for aggregation --- delete() issues with django.db.models.query: delete_objects

[JeffH]

Russ: Thanks for your reply!

1. I don't consider my views-as-models approach elegant at the
implementation level, but:
  * it is dead simple to use once set up (it's just the Django model
and database API)
  * it allows for limited aggregation support (views are created at
install time, so real ad hoc reporting would have to be done with
custom model methods)
  * it works with querysets since the aggregated columns are defined
as Django model fields, so presenting a table of aggregated data with
an arbitrary selection of rows only requires one actual database query
(versus many queries when iterating over instances invoking a model
method)
  * SQL code stays in SQL script files that are part of Django's
design (sqlinitialdata) and stays out of my python code
Ideally Django classes for the table and view functionality would
share a common ancestor so they share an API, and table-specific
behavior like delete_objects would be defined above the common (i.e.
SELECT) functionality. Realistically, such a refactoring is unlikely
before my next few projects are due (no sarcasm intended).

2. With hindsight, delete_objects() behavior of Django appears to be
specifically desired by the developers so I'll just change my working
copy to just check for a class attribute like "not_updatable", and
abort batch deletes for related object classes with that attribute.
Given the specific nature of my need (prevent cascading deletes of
views) it will be much more efficient than calling an empty delete()
method for each object.

3. That said, my delete_objects() hack was an attempt to solve the
more general problem of using an overridden delete() without any
special flags while allowing for the possibility of model subclassing
in the future, because it seemed that respecting an overridden
delete() was an important end in itself from an object integrity
perspective. I had hoped that the developers might be intrigued by the
concept behind the hack (checking once per related class whether a
user has overridden delete() and defaulting to the usual batch delete)
because of the inherent object-functionality-versus-database-
efficiency tension in an ORM. My hack offers options - the user can
choose to give up database speed for object-level functionality - and
options are always good as long as they are documented: "WARNING: Your
database may slow to a crawl if you override delete()!" Checking if
delete() was overridden is not a performance hit, so you don't lose
anything by offering the option. For my application, aggregate
reporting is far more common than deletion, so it needs to be
efficient and convenient to code.

4. Regarding documentation, I will put in a ticket for the
documentation on the relevant section
http://www.djangoproject.com/documentation/model-api/#overriding-default-model-methods
of the model-api page. That section invites people to override save()
and delete() but only discusses save() and the implication (by
omission) that overriding delete() is analogous is incorrect.

5. A big ongoing thanks to all of Django's contributors. You rock!

Thanks for reading this.

Cheers,
Jeff

Unique=true

[[EMAIL PROTECTED]]

OK, fixed the above problem -- figured out that it was related to my
setting unique=True on a field. But that raises the larger question...

I have a bit of data that may or may not exist... a identifier on the
user that not all users will have, but if they DO have it, it needs to
be unique to that user. Apparently, unique=True isn't what I want,
because the second user without it throws the above duplicate entry
error, so how do I handle that?

Django and ActionScript 3 Templates

[SamFeltus]

I was wondering if anyone had used Django to generate ActionScript for
the MXMLC compiler?  I have been  tinkered with using TurboGears to
create/edit Flash movies.  Here is an example of the ongoing comical
experiment...

http://samfeltus.com/as3/mardi_gras.html

I'm considering writing some generic ActionScript templates that can
used to edit/generate Flash movies in Python web frameworks.  Perhaps
they would be useful.

Is there any preexisting work to build on?

RE: is there any host servers that supports Django based sites?

[Sells, Fred]

I suggest you contact webfaction or others and ask them to give you 1 month
of free hosting of a developed site, with the plan that your client would
then pay to have his stuff hosted there if he liked it.  After a few
successes, you might get them to give you a generic beta site.

template not raising error (newforms related ?)

[olivier]

Hi all,

I'm having some debugging issue with Django templating and newforms.
I'm using a form_for_model class, and I define a custom layout method,
in the vein of as_ul or as_table).
It looks like :

EntryForm = forms.form_for_model(models.Entry, form = CustomForm)

class CustomForm(forms.BaseForm):
def as_custom(self):
"""custom layout"""
...
# Error on purpose
assert 1 == 0
return "..."


Now, if I call {{entry_form.as_custom}} in my template, the more I can
get for debugging is TEMPLATE_STRING_IF_INVALID, but there is no way
Django tells me what is going wrong (in my case AssetionError at
line ...).

Am I missing something ? Some obscure setting maybe ;o) ?

I understand it's Django philosophy not to raise any error, but a
debugging trace, maybe in the server console, would be nice.

Cheers,

   Olivier

[Tim Chase]

This sounded kinda zen when I first heard it...running Django 
apps on a host without Django, sound of one hand clapping, and 
all that.

The important factors are the webserver interface (mod_python or 
fastcgi) and that python is available.  If your server meets 
these criteria, you can install django as it's only a bunch of 
python code that can be unzipped/untarred/"svn co"'ed in the 
directory of your choice.

There are other aspects such as required libraries (a python 
interface to your DB engine of choice/availability), but 
otherwise, there's minimal fuss.

A list of known Django-friendly webhosts is maintained at

http://code.djangoproject.com/wiki/DjangoFriendlyWebHosts

If you find one that isn't on the list that ends up working for 
you, it would be a service to add it to the wiki.

Re: flatpages issues

[John-Scott Atlakson]

Ah ha! I just looked through my settings.py file and noticed the setting:
SITE_ID = 1
I decided to double check the raw data for the django_sites table and my
site id is '2'. (I think id 1 used to be 'example.com' but I had deleted it
instead of renaming it, thus creating a mismatch with SITE_ID). Once I
changed the SITE_ID value everything started working. I deleted the item
from urlpatterns, and you're right, it's unnecessary. Thanks for attempting
to get me sorted out.

John-Scott.

No, it's not; the fallback middleware works fine for me. If it's not

don't you post your settings.py and we'll take a look?

from Team, it loads fine.  The same if I use it as a ForeignKey
field.  I'm using the latest stable, 0.96.

Re: Spawning Subprocesses under mod_python

[Giovanni Giorgi]

I have used the subprocess module with success.
I have used it only on command line based script under Linux, but I
think it can work inside mod_python.
If you plan to use it I suggest you to reboot the apache one a day, to
prevent yourself againt resource and/or memory leaks.

Re: flatpages issues

[John-Scott]

Can someone in the know confirm or deny that adding the catch-all line
to urls.py is in fact required to invoke flatpages? I checked out the
source for djangoproject.com and it has this as the last item in
urlpatterns:

(r'', include('django.contrib.flatpages.urls')),

If this is required, should I file a ticket on the documentation to
get this included in the instructions?

Thanks.

Throwing error in admin using ManyToManyField(Site)

[Jeff]

I'm throwing an error when loading the admin edit page for an instance
of a model.  The exception itself is a TypeError, "Cannot resolve
keyword 'team' into field."  It is being raised at db.models.query
line 938.  I've included the full trace below.

The model is Team, which has a ManyToMany relationship with Site, and
a ForeignKey field of Sport.  Both tables are below as well.

I can't for the life of me figure out what the problem is.  The team
has an entry under app_team_sites, the sport exists, and the site
listed in app_team_sites for the team exists.  Does anyone have any
ideas?  I don't see anything relevant on the django bug tracker.

Re: HttpResponseRedirect and IE6

[Bob Dively]

I'm also having a problem with redirecting and IE6. User enters data
in an HTML form, clicks save button and gets IE's "The page cannot be
displayed" error. In this case the initial URL is /household123/client/
add/ and the browser should be redirected to /household123/. However,
the URL is is still /household123/client/add/ when the IE error page
is displayed. If page is refreshed, a blank HTML form is displayed (as
one would expect). The original record was successfully saved to the
DB. The behavior happens only intermittently - probably 3 times out of
4 the redirection happens as expected. IE 6 on WinXP with Django
running on Win2003 with Apache 2.2 listening on port 8080. Code
below.

I have some suspicion that an Apache misconfiguration is at fault as
I'm also experiencing problems with CSS includes and images not being
properly rendered, as if the browser has requested them but the server
hasn't served them. For example, if I'm on a page that's properly
displayed and refresh that page 5 times in a row, the browser might
not render the CSS one of those times, even though the files are all
there and nothing has changed between refreshes. This problem occurs
with both Firefox and IE, whereas the redirection issue happens only
with IE.

def add(request, household_id):

  ClientForm = forms.models.form_for_model(Client)

 
ClientForm.base_fields['Birth_Dat'].widget=forms.widgets.TextInput(attrs={'class':'w8em
format-m-d-y divider-slash no-transparency' })
 
ClientForm.base_fields['Intake_Dat'].widget=forms.widgets.TextInput(attrs={'class':'w8em
format-m-d-y divider-slash no-transparency' })

  if request.method == 'POST':
f = ClientForm(request.POST)
if f.is_valid():
  f2 = f.save(commit=False)
  f2.Add_Dat = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
  f2.Add_User = request.user.username
  f2.household_id = household_id
  f2.save()
  return HttpResponseRedirect('/household' + household_id + '/')
  else:
f = ClientForm()

  return render_to_response('client_form.html', {'form': f, 'request':
request, 'media_url': settings.MEDIA_URL} )

memcached Cookie Problems

[Alexander]

Hi,

I'm currently streamlining my django app for speed. I'm using
memcached on my server (apache, django svn trunk version: 5718) with
the following settings.py:
CACHE_BACKEND = 'memcached://127.0.0.1:11211/'
CACHE_MIDDLEWARE_SECONDS = 180
MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.middleware.cache.CacheMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.doc.XViewMiddleware',
)

>From my understanding should everything work fine, even with
authentication and sessions. But sessions and login/logout does not
work properly, which means that I can login and logout once ... but if
I try to login a second time (within the 180 secs cache timeout)
django won't set a session (test) cookie for the first request and
therefore failing to authenticate the user at the 2nd request (the
actual POST with the login data), because it thinks the browser does
not support cookies. As you can see below at  "Debug Header 1, 2".

The debug log output from funkload (very good web app testing tool by
the way) is the following:

After waiting for 180 secs (or until my cache is expired) everything
works correctly again ... (just for the first request)
The questions here is: Is it a bug ... or is it feature?

Thanks for helping

generic views and selection for foreignkey

[Przemek Gawronski]

Hi, in the model I've got:

class Client(models.Model):
   name = models.CharField(maxlength=200)

class Workorder(models.Model):
   client = models.ForeignKey(Client)
   name = models.CharField(maxlength=200)

As for input I'm using generic views (create_update.create_object,..).
How can I get an selection widget in the form for Workorders with a list
of clients? Is there an automatic way to do it (like in the admin panel)?

This is a Postgres error, telling you that the psycopg can't connect
to the Postgres DB.

You need to play around with your pg_hba.conf and/or postgres.conf
files to set up appropriate permissions for access. See the Postgres
documentation for details on what you need to do.

For Django purposes, the debug check is that you must be able to call:

> psql -U USERNAME -h HOST -p PORT -d DATABASE_NAME

where USERNAME, HOST, PORT, and DATABASE_NAME are the values in your
Django settings file.

You're looking at the wrong bit of documentation. Your problem isn't
about accessing data via a manager - it's about composing queries. The
relevant bit is here:

Re: Efficient reverse access on ForeignKey?

[jj]

Excellent, this works!

Now, probably the documentation is misleading. From documentation/db-
api:


You cannot access a reverse ForeignKey Manager from the class; it
must be accessed from an instance. Example:
Blog.entry_set # Raises AttributeError: "Manager must be
accessed via instance".


I don't think I saw elsewhere that '_set' had not to be used.

Anyway, thanks Russ,

JJ.

Out of curiosity, what were you disappointed with? The common
complaint (and one that needs to be fixed) is that the current system
only works with authenticated users, but if there are more problems
I'd be interested to hear them.

Improve the dynamic generation of a form with newforms library

[yml]

Hello Djangonauts,

After spending sometimes to learn using the test/fail/correct cycle I
have finally reach a point where I have something that more or less do
what I want. However since one of the objectives of the project I am
working on was to improve my knowledge on django I would like to read
from you how to improve what I have done.

The goal is to generate dynamically a form using the newforms
library.
This forms should all the user to create an Interview
(models.py:http://dpaste.com/hold/14560/ )
What I have done so far is create this custom form:

class AnswerPollForm(forms.Form):
def __init__(self, poll_id, *args, **kwargs):
super(AnswerPollForm, self).__init__(*args, **kwargs)
self.poll = Poll.objects.get(id=poll_id)
for c in self.poll.choice_set.iterator():
self.fields[c.id] =
forms.BooleanField(label=c.choice,required=False)

  That I use in this view (http://dpaste.com/hold/14562/). The
interesting part is that I create a list of tuple made with the polls
and the forms representing them. This allow  me to create a single
form that I can use to collect the interview to a survey.

list_answer_forms =[]
for poll in survey.poll_set.iterator():
list_answer_forms.append((poll,AnswerPollForm(poll.id)))
[...]
return render_to_response('dj_survey/template/
add_interview_forms.html',
  {'list_answer_forms':
list_answer_forms,
  'survey': survey,
  'request': request})

This list of forms is then used in the following template:
Welcome to {{ survey.name }}
{{ survey.description }} 

{% for poll,form in list_answer_forms %}
{{ poll.title }} | {{ poll.question }}

{{ form.as_ul }}

{% endfor %}
 



 This is not bat but i would prefer if instead of the list of tuple
containing my forms could directly instantiate a "all in one" form.
 This would avoid the loop on list_answer_forms. This is were I get
stuck. Could you please let me know how to add html text between the
field?
 like "{{ poll.title }} | {{ poll.question }}"

 Any other improvement is more than welcome.
 Thank you for your time.

 Regards,

Re: About create a database table dynamicly

[Ned Batchelder]

Nick, if all of your dynamically-created tables in fact have the same 
schema (set of columns), then you definitely should make one table for 
all your users to share.  Be sure to index the columns that will be used 
in your WHERE clauses, and your table will perform fine.

The __dict__ option described elsewhere will work, but could introduce
some interesting name clashes (depending on the exact names in use).

Another option is to use the values() clause on a queryset. This
modifies a query set to return a dictionary of values, rather than a
list of objects (or a single object, in the case of get):

>>> User.objects.values('username','email').get(pk=1)
{'username': u'freakboy', 'email': u'[EMAIL PROTECTED]'}

Try:

 q = q.filter(foreignprint__country='Holland')

foreignprint doesn't get an underscore unless it is defined that way;
the _set suffix is not used when composing queries.

Coulix has a cool solution to your topic. He has small apllication
that can handle the mapping.
And he points to some files which provide a ip2country mapping and
country flags for you.

Thank you Malcolm! It's fixed!

The exception was:

Exception Type: SyntaxError
Exception Value:invalid syntax (urls.py, line 24)

Caught an exception while rendering: invalid syntax (urls.py, line 24)

I've looked into the post urls.py many times!!


I've used the manage.py shell and there I could see a full path to the
urls.py
which was my user_details/urls.py.

Weird.. it worked fine when not using permalink..

Also, I've had some regexp errors in urls.py (urlresolve() couldn't
resolve it).
All fixed, and working.

Will look into the manage.py shell next time before posting :-)

Thanks again for help, and for unicode branch.

Re: How to make dictionary out of model instance

[Ben van Staveren]

If you have an instance, you could just do:

myUserModelInstance.__dict__ -- that'll get you the data you want,  
and a bunch of extra stuff you most likely don't want. I don't really  
recommend doing this either, since it's not "the right way" IMO, but  
it solves your problem.

Although you give the traceback, you don't say what exception is raised.
So it's hard to guess.

A first step to debug this would be to try it at the interactive prompt
("manage.py shell") and see what happens when you call
get_absolute_url() on some model instances.

Malcolm

It seems the problem mysteriously went away. Now it works just like I

Efficient reverse access on ForeignKey?

[jj]

Suppose I'm building a large complex query on a Book (via the HTTP
query string -details omitted):
q = Book.objects
if year:
q = q.filter(publication_date__year=year)
if month:
q = q.filter(publication_date__month=month)
etc. (more complex queries in practice)

Now I'd like to restrict the query to books which have been printed in
'Holland':
q = q.filter(foreign_print_set__country='Holland')

where:
class ForeignPrint(models.Model):
book = ForeignKey(Book)
country = CharField()

But this is not possible on ForeignKeys. Reverse access only works for
instances, not managers.

How can I do this efficiently?

JJ.

does anyone in the django community know of a public algorithm to get

If such a thing doesn't exist do you know of a service with an API
which does it?
Or maybe such a functionality will be available with the upcoming
Geodjango?

Database tables can contain millions and millions of rows and they will
still perform quickly. You are trying to do something that is very
fragile to avoid doing something that databases are designed to handle.
Don't optimise prematurely.

using its replacement using Popen() as detailed here:

http://www.python.org/doc/2.4.3/lib/node243.html

I want to be able to retrieve the results of the subprocess (file
command) as it is printed on STDOUT and STDERR.

I found this thread from 2006 but it talks about spawning a daemon
process from mod_python. My case is a bit different I think as I only
want to execute an external subprocess, capture its output and have
mod_python go on its merry way.

Anyone else with success/horror stories to tell about spawning
subprocesses under mod_python please share :)

Thanks in advance.
