As embarrassing as it sounds, I don't have good numbers available yet. There

Good to hear, I like keeping things separate. I lied a little earlier, I do
have a shared directory that contains .so's - the per project site directory
is things I track via their source repositories (django and pretty much
anything related) and until now dont contain any .so. I'm gonna keep it as
is.

I considered nginx, but I've been playing with S3 and I think I'm going to
use that as a poor mans edge system for my static content. But I'll keep
this in mind. Would using a event mpm help if I didnt have to serve static
content or need Keep-Alive?

Re: Django along with PHP - avoiding Apache crashes

[DULMANDAKH Sukhbaatar]

I use apache2's mpm-worker which is threaded and means very fast,
requires less resource. And use PHP5 as a fastcgi, django (through
python) also as fastcgi.

This setup maybe difficult compared to apache modules based setup. but
proven to be very fast, and no side effects.

Re: appeal for help with #9232

[Graham Dumpleton]

The OP, if they don't need mod_python should also disable it and not
load it into Apache at the same time as mod_wsgi. The mod_python
versions is quite old and buggy and mod_python can interfere with
mod_wsgi especially causing certain configuration options for mod_wsgi
to not work. The mod_wsgi version is also not the latest, should try
with mod_wsgi 2.3. No known issues with uploading with mod_wsgi 2.0,
but still better to use the latest.

Just because binary distributions still only provide old versions
doesn't mean they are the best to use and bug free.

How many processes in each daemon group and how many threads? A lot of
sites would work quite happily with single daemon process with a dozen
or so threads, which is what WSGIDaemonProcess gives you as default
when you do not define number of processes and threads. Thus, don't
get carried away and create more processes than you really need to.

Can you post the Apache configuration showing relationship between
sites and daemon process groups? Can then possibly comment better.

Also indicate how much traffic each site gets and whether any would
potentially be idle for periods, as can then look at inactivity

The code size is generally not the issue, but runtime application

Rather than event MPM, would suggest using nginx as a front end, with
nginx serving requests for static files and then proxying other
requests through to Apache/mod_wsgi. This is because nginx is arguably
better at serving static files and maintaining many open connections
with keep alive. The Apache/mod_wsgi instance would then only be
handling dynamic requests and all connections would come from local
nginx. Even if keep alive working there, depending on how optimised
nginx is, it can possibly reuse the connections over time for requests
from different originating clients in a more efficient way, thereby
keeping the memory overhead in Apache which generally arises from
maintaining open connections from lots of different clients.

It is not necessary to be running Apache worker MPM to run mod_wsgi,
it will work quite happily in Apache prefork MPM, just like mod_python
can. Also note that if you have problems with mod_wsgi, using
mod_python will not help as it can be impacted by exactly the same
problems.

Now, which MPM you use is not the problem you seem to think it is. The
real problem is generally going to be mismatches in what versions of
shared libraries that PHP uses compared to what various Python modules
require. The main culprit for this is MySQL as PHP generally uses a
non reentrant variant of MySQL client libraries where as Python MySQL
module generally uses a reentrant variant of the library. Result of
this can be Apache crashing.

Other problems can also arise if you are using Debian and the broken
Python 2.4 that Debian released. Specifically, Debian folks fiddled
with the hash module code in Python 2.4 and caused a conflict between
it and a hash module in PHP. This can cause problems with session IDs
being generated incorrectly and causing session mechanisms to fail, or
could also crash Apache.

These issues and others can be found described in:

  http://code.google.com/p/modwsgi/wiki/ApplicationIssues

Now, although mod_wsgi can be used with Apache prefork MPM and you can
run your Django application in embedded mode, because prefork means
more Apache child processes, you might not find it desirable that your
fat Django application then causes Apache as a whole to use up so much
memory. In this situation, don't run your Django in mod_wsgi embedded
mode, instead create a mod_wsgi daemon mode process groups and
delegate Django to run in that instead. Use one multithreaded daemon
mode process, or if your Django application isn't thread safe, a small
number of single threaded processes.

For some quick examples of embedded versus daemon mode configuration
see:

  http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide

You should also go through other documentation on the mod_wsgi site
properly as well though. Don't assume that just reading one page, or
some ones blog on how they did it, or relying on answers to questions
you get from irc channels is going to be sufficient. This is why the
documentation exists.

I see the same behavior, at least for models that don't have a lot of
columns with wide text in the change list.  It appears that, with a filter
present, the columns are narrowed to only however wide they need to be to
fit the longest entry in the column, whereas without a filter the columns
are expanded so that the full set covers the whole width of the screen.  I
expect it's a side-effect of the css needed to get the filter in place;
whether it's a necessary or accidental side-effect I don't know -- I've
never cared about it enough to look into it, especially since css isn't my
favorite thing to play with.

You are saying this is code from someone else and they claim it runs on
0.96?  If so, I believe they are wrong.  That import won't work prior to
r5898:

http://code.djangoproject.com/changeset/5898

which is when the django.core.management package was created, along with
call_command.  Django 0.96 was tagged around r4810, about 1000 revisions and
six months earlier. It may be the original developer was using some svn
checkout of Django from between 0.96 and 1.0.

S3Storage, FileField -- default_storage.exists() has unwanted side-effects

[Info Cascade]

I have a model that has a FileField storage field.
The default_storage system is S3Storage.
I noticed that I was getting unusual results when I simply tried to
verify whether the file existed on disk using the
default_storage.exists() method.
If I call it with the FileField object, it causes Django to actually try
to *get* the file, which is not what I intend.  The S3Storage module
implements exists() as a simple http HEAD request. That part works
fine.  But then Django starts getting the file which eventually results
in an error, so it appears the file doesn't exist when really it does.  
(The file is an audio file, which triggers a series of byte-range
requests, the final one having incorrect value, so I'm getting a series
of 206 codes followed by 416 error code. It causes a key error in
S3Storage or S3 on 'etag'.)

I was able to work around it by using the str() function, which results
in the correct behavior.

Anyway, it was non-intuitive for me that checking whether a file exists
would make Django do a GET on it!  Is this a bug or do I just not
understand what's going on beneath the surface?  (Which is the case,
actually.)  Can someone explain this?

Hi Karen. Since I'm using a Japanese version of windows, the command
prompt already displays messages and file names in Japanese
characters. I didn't know about the commands you mentioned, thanks for
letting me know. However, when I made the two changes you describe,
Japanese characters become unreadable.

As I said before, if I write a simple function in python which outputs
a Japanese string, I can call that function in a normal python shell
and everything works. It's only when I use the manage.py shell and try
to perform the code above that things go wrong.

Any other suggestions greatly appreciated.

The problem is with PHP, not mod_wsgi. The PHP manual has this FAQ entry: "*Why
shouldn't I use Apache2 with a threaded MPM in a production
environment?"*.
Because PHP has a high number of C extensions, which in turn use existing
libraries, your success really depends on the php modules, the libraries
they use, and how they were all compiled. If you need to run PHP and
mod_wsgi together, the prefork mpm is best.

mod_wsgi alone will will work safely in a threaded environment and any of
the non-experimental mpms.

It's not a generally re-creatable problem. Using your project on one of my
machines (Ubuntu) with Django 1.0, Apache 2.2 & mod_wsgi 2.3 an upload of a
700M file takes about a minute and a half (during which time I can see the
tmp upload file continually growing in size), then gets an error on the
redirect at the end of the view since "top_folders" is not reversable in the
testproj config.

Random question that cross my mind:

Are you sure you have a clean install of Django 1.0 -- that is you removed
any old level before installing 1.0?

Are you trying the upload from a machine with a known good network
connection to the server (or from the sever machine itself?).

Do you see the same behavior if you run under the development server?

Well it might also just work. I am running a site with PHP, django via
mod_python, and MySQL without any problems on Fedora Core 6.

How to setup django-apache-mod_wsgi without killing existing php site?

[Håkan Waara]

Hi folks,

I'm in the process of for the first time deploying a django site that  
(unfortunately) needs to share its Apache with an existing PHP site.

I've been reading a bunch about mod_wsgi and in many places there are  
mentions that setting up apache with mpm-worker (basically  
multithreaded mode) will not work if you're also hosting a PHP site on  
the same Apache; Apache will crash, and the world will collapse...

What I haven't been able to find out is if it's possible/worth it to  
use mod_wsgi (efficiently) in this situation at all, and if so how to  
do it?

Does anyone have other suggestions on how to avoid mod_python in this  
situation? Should I have a look at nginx for example?

Any hints appreciated!

Multiple Copies of Libraries, Apache/mod_wsgi and Performance

[Naitik Shah]

I'm serving a few sites from a tiny VPS, and I'm quite happy with a
Apache/mod_wsgi setup. I've managed to reduce the Apache footprint by having
only a few necessary modules loaded. mod_wsgi is setup to use daemon mode
and start multiple processes per site.

Currently, each site has its own python-path and the system python
installation does not contain anything but stock python modules. Each site
has its own copy of Django and various other libraries. Is there a
performance gain to be had by having the sites share these libraries? They
are different processes, so I think not, but I'm not quite sure. Also,
another benefit that I can think of is that if the files were the same, the
OS (Linux 2.6.27) would be able to cache them better, but again I'm not
quite sure.

This is probably a micro enhancement, but I'm trying hard to keep the memory
consumption low.


-Naitik

ps: Another enhancement I'm looking into when I have time is the event mpm,
but that one requires me to give up my distro apache. Thoughts?

Re: Adding properties to models at run-time.

[Alex G]

Thanks for the reply, DR.

How would I use the generic relationship without the backward link?

I have the normal auth.user class, and I have the my.user class that
extends it and has a polymorphic link pointing at auth.user.  The
problem occurs when I collect a login/password, because I can't lookup
my.user without the backward link, that is I can't
my.user.filter(account__username = x, account__password = y) because
polymorphic links don't allow this.  I also can't move in reverse, the
auth.user.authenticate(username, password) function returns an
auth.user, and I am unclear as to how I would get a my.user from this
information without calling for my.user.objects.all() and comparing
the link (which seems terribly, terribly inefficient...).  Is there a
way to start with the target (auth.user) and get to my.user backward
via the contenttype?

I know about AUTH_PROFILE_MODULE, but the problem is that the goal is
to have multiple user classes.  Ideally there would be a way to
specify the user model as an attribute of the auth.user model (which
would be the heretofore missing backward link), but barring that this
isn't much use to me because the AUTH_PROFILE_MODULE would have
multiple values.

Any clues?

Thanks,

Alex.

Re: multiselect populated by another app

[webcomm]

Bump.

There must be a way to do this, right?  I have looked all over... the
documentation seems to indicate that there is no way to do this in
django, which is surprising, since this is a necessary part of so many
programs.

Is there really no way to populate a mutiselect with values from
another app?

The Definitive Guide to Django says that a ManyToManyField will take
as its one argument only the name of a class from the same app.  If
that's true, I don't see how anyone could develop a categories app in
django... perhaps I'm missing something?

Thanks in advance for your help,
Ryan

I've been thinking about this recently (going to have a working
solution for the same problem pretty soon...). The cleanest solution
I've came with so far is to make the view function only return a
context, then wrap the view function in a decorator that takes care of
rendering, based on request informations. The points I'm yet really
happy with are:
- how to tell the rendering decorator what we want to render
- how to avoid template duplication for 'full' rendering and 'partial'
rendering

wrt/ first point, the simplest solution IMHO is to pass a render=json
or render=partial argument in the query string (default being
rendering the 'full' page). My main problem is with second point. I
have a working scheme using two templates, the 'full' one doing an
include of the 'partial' one. This should work, but I still don't like
having two distinct templates.

I don't have the (prototype) code at hand here, but from memory it's
something like:

class render_with(object):
def __init__(self, partial, full):
self.partial_template_path=fragment
self.full_template_path = full

def __call__(self, view):
self.view = view
return self.render

def render_json(self, request, context):
# this is in djangosnippets IIRC
return JsonResponse(context)

def render_partial(self, request, context):
return render_to_response(
self.partial_template_path,
context,
context_instance=RequestContext(request)
)

def render_full(self, request, context):
context['partial_include'] = self.partial_template_path
return render_to_response(
self.full_template_path,
context,
context_instance=RequestContext(request)
)

def render(self, request, *args, **kw)
context = self.view(request, *args, **kw)
#  the view can still return a response object
if isinstance(context, HttpResponse):
return context
# ok, it's really a context
render_mode = request.REQUEST.get('render', 'full')
render_method = getattr(self, 'render_%s' % render_mode)
return render_method(request, context)


Then you use it that way:

# myview.py
@render_with(partial='mypartial.html', full='myfull.html')
def myview(request, somearg):
   return dict(yadda='yadda')

# mypartial.html

Yadda : {{ yadda }}


# myfull.html
{% extends 'base.html' %}

{% block stuff %}
{{ yadday }} stuff here
{% endblock %}

{% block main %}
{% include partial_include %}
{% endblock %}

{% block other %}
other {{ yadda }} stuff here
{% endblock %}

Well, you can use generic relations without the backwards link, by
simply looking up the content_type/object_id in the related class.

But for your use case, a much better way is to use the built-in
AUTH_PROFILE_MODULE setting, which allows you to nominate a class
which extends User, and enables a user.get_profile() method. See
http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users

Table width when using list_filter

[Fabio Natali]

Hi everybody!

I'm a bit confused about the behaviour of my change list page.

If I enable list_filter the table (the one listing my model instances)
"shrinks" and its width is no more 100% of the space available. All
the columns and data are perfeclty shown, it's just that everything is
more narrow. Obviously, part of the width is taken by the list_filter
window, but the table shrinks down far more.

Is this behaviour normal? Is there any reason for it?

I use trunk django and a cutting edge firefox browser.

Cheers, Fabio.

Adding properties to models at run-time.

[Alex G]

Hi,

I've been trying for some time to create a polymorphic link with a
backwards-link from the associated model.  The problem is the model is
django.contrib.auth.models.User...  Is there any way to add this
functionality without changing the django core?  Trying to call
setattr(django.contrib.auth.models.User, 'target',
generic.GenericRelation(MyUser) does not work.  It instantiates an
attribute named 'target', but it doesn't work in the manner
intended...

from django.contrib.auth.models import User as Account
from django.contrib.contenttypes.models import ContentType
from django.contrib.contenttypes import generic
class User(models.Model):
account_polymorphic_link = models.ForeignKey(ContentType)
account_id = models.PositiveIntegerField()
account = generic.GenericForeignKey('account_polymorphic_link',
'account_id')

setattr(Account, 'target', generic.GenericRelation(User)) #this
doesn't seem to work

My problem is that I'm using auth.User (Account in the above example)
to store username/password and to leverage permissions and such, but I
can't look someone up by username and get at the information in my
derivative class...

Does anyone have any ideas/suggestions?

Thank you,

Alex.

# This allows me to add a custom clean() method to the formset made of

# email.
class BaseAuthorFormSet(BaseFormSet):
def clean(self):
super(BaseAuthorFormSet,self).clean()
cd=[]
try:
if self.cleaned_data:
for dct in self.cleaned_data:

and dct['display_name']

if cd:
return cd

If anyone has a hint, or has run across a similar circumstance, I

PyCon 2009 (US) - Call for tutorials Extended to 11/3

[Greg Lindstrom]

We have had requests to extend the deadline for submitting Tutorial
Proposals for PyCon 2009 (US) through the weekend and are willing to do so.
We will accept tutorial proposals through Monday, November 3.

--greg

==

The period for submitting tutorial proposals for Pycon 2009 (US) is open and
will continue through Monday, November 3rd. This year features two
"pre-conference" days devoted to tutorials on Wednesday March 25 & Thursday
March 26 in Chicago. This allows for more classes than ever.

Tutorials are 3-hours long on a specific topic of your choice. Last year we
featured classes on Learning Python, Web Development, Scientific Computing,
and many more. Class size varied from 10 to over 60 students. The extended
time spent in class allows teachers to cover a lot of material while
allowing for interaction with students.

The full Call for Tutorial Proposals, including submission details, an
example proposal as well as a template, is available at <
http://us.pycon.org/2009/tutorials/proposals/>.

Tutorial selections will be announced in early December to give you time to
prepare your class and PyCon will compensate instructors US$1,500 per
tutorial.

If you have any questions, please contact [EMAIL PROTECTED]

Greg Lindstrom
Tutorial Coordinator, PyCon 2009 (US)

Multiple types of output (HTML, JS), same view.

[Joe Murphy]

Hi,

So I've got a bunch of views that I need to output in three forms:
HTML with the site wrapper (header, footer etc.), HTML without the
site wrapper, and JS. The templates are really, really similar.

I'm thinking of using a url pattern like:
r'^blog/blah(?P[-\.\/\w]+)$'
so that blog/blah/ would return the HTML with site wrapper, blog/
blah.html would return the HTML without wrapper, and blog/blah.js
would return the javascript.

Doing this means I'm putting logic in all the views that need this
functionality -- and, then, building slightly-different templates for
each of the three outputs.

There's something about this that seems wrong, but I can't imagine a
cleaner solution. Any thoughts?

Joe

Re: Migrate app from MySQL to PostgreSQL

[Naitik Shah]

I ran into issues with this approach as well - first uniqueness constraints
were failing, which I managed to fix manually. Next I got ContentType
matching query issues, which I have not fixed yet.

I was hoping to come up with a generic migration process since I have a few
other sites on MySQL. But this is my first foray into PostgreSQL, so maybe I
should just take a simpler approach and write a task specific migration
script until I'm convinced I should move all my sites to PostgreSQL.

ManyToMany views

[ndarkduck]

Hi, thanks for making a mailing list about inqueries.

I want to know if is possible to autogenerate a view that allows a
many to many relationship with an extra field to be captured.

ie:

class statictests(models.Model):
   statictests_id = models.AutoField(primary_key=True);
statictests_name = models.CharField(max_length=90);

class proyect(models.Model):
   tests = models.ManyToManyField(statictests, through =
'num_tests');

class num_tests_unidades(models.Model):
un_alt_tec = models.ForeignKey(statictests);
res_proy_ver = models.ForeignKey(proyect);
num_tests = models.IntegerField();

The view that results from this code is:
--

bababa.
bebe.
bibi
etc1.
etc2.

-
I need something that specifies the attribute of the relationship.

Thanks in advance

Re: Using TEMPLATE_DIRS and impact on admin pages path

[RossGK]

Sorry - more info in dribs and drabs as i get it.

I thought I could add a path to the admin templates, but no luck.
Tried adding

/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-
packages/django/contrib/admin/templates

to the TEMPLATE_DIRS  and it has no effect.
Interestingly with my template path in there, I'm still able to get
the admin log-in page, but then it fails with this info:


'adminapplist' is not a valid tag library: Could not load template
library from django.templatetags.adminapplist, No module named
adminapplist

Request Method: GET
Request URL:http://localhost:8000/admin/
Exception Type: TemplateSyntaxError
etc...

Hope that sparks some recognition for someone.  I guess for now, I'll
just have to comment out my template dir whenever I need the admin
functions :(

I think Django sounds ideal in your situation.

* A django "app" is generally something that is reusable. A set of  
views, models, forms that do one function, and do it well. Read more  
about this here: 
http://stackoverflow.com/questions/64237/when-to-create-a-new-app-with-startapp-in-django

* To use the same set of objects (products) but a subset for each  
different site, you can use the built-in sites framework. Basically  
each product will have a ManyToMany-relation to a set of sites  
(foo.com, bar.com) that tags which site(s) it belongs to. See 
http://docs.djangoproject.com/en/dev/ref/contrib/sites/?from=olddocs 
.

Finally, hopefully you've gone through the tutorial? There's some  
great docs over here that help you wrap your head around django and  
the usual workflow: http://docs.djangoproject.com/en/dev/

Hope this helps and good luck!

Using TEMPLATE_DIRS and impact on admin pages path

[RossGK]

Moving development from win32 to mac and one little thing I don't
understand about template paths.
Got django set up and DB in place etc, and was able to use the admin
functions to populate some DB content. Everything seemed fine.

But, initially on the Mac, my templates weren't being found, though my
urls.py seemed to be pointing in the right direction.

I'm probably forgetting something I knew when on win32 a few months
back - but I noticed that the settings.py has a TEMPLATE_DIRS
variable, and so I put the path to my templates and server-side
content there.

Everything is working fine now, and development continues.  BUT if I
try to go and use the admin feature to do database stuff, I get a
failure to connect from my browser.   If I comment out the
TEMPLATE_DIRS path that I added, admin pages can again connect.

Now, sure I can find and add the path to the admin templates to
TEMPLATE_DIRS - is that the right approach, or am I getting into
kludgy land here?   Any thoughts about how django was finding my
templates back when I was on PC (which I don't have anymore) without
using TEMPLATE_DIRS?

Any help is appreciated.

Handling multiple sites branched off of one main site

[Wayne M]

I'm looking at using Django for a project at work, which is an e-
commerce storefront that *must* be able to support multiple
storefronts, each storefront filtering a subset of the master products
database.  For example, we might have a furniture store with the URL
furniture.mycompany.com or a recycled products store with the URL
green.mycompany.com.  There is also the requirement to allow different
full domain names that point to a certain storefront, e.g.
www.mycompanyfurniture.com should be the same as
furniture.mycompany.com

In addition, one site needs to have certain tables kept separate (it's
another company that we do the processing work for) than the rest, but
use the master products and categories table.  Orders, customers,
pricing, etc. need to be separate entities since they will be
different from the other tables.

Technically speaking, how would I best go about doing this?  The view
for each subsection would need to be different to filter specific
products, but the models are the same (e.g. products) and there is
only one database table.  Basically each storefront would have its own
base template that sets the look and feel, but all the other templates
(list, details, search, etc) would be the same as the "main"
storefront.

In Django, is the concept of an "app" analogous to the "module"
mindset I'm referring to here?  For example, would a directory
structure like this fulfil this requirement?:

myproject
 |- manage.py
 |- urls.py
 |- main_store
  |- models.py
  |- views.py
  |- templates
   |- base.html
   |- index.html
 |- furniture_store
  |- models.py (not used, uses main_store's)
  |- views.py
  |- templates
   |- base.html (?? use main_store's templates for everything except
base ??)
 |- green_store
  |- models.py (not used, uses main_store's)
  |- views.py
  |- templates
   |- base.html (?? use main_store's templates for everything except
base ??)
 |- companyb
  |- models.py (only what differs, since products et all are
identical)
  |- views.py
  |- templates
   |- base.html
   |- index.html

Running this over in my head is giving me a headache because it seems
very convoluted.  I'm not even sure if Django would be my best choice
in a situation like this because of the almost infinite flexibility
required and the fact that there needs to be separate pieces of the
same application (the main store) as well as a totally separate
application (the other company's store) but I don't want to duplicate
the entire thing; our current spaghetti-code system (VBScript) does
exactly this and it makes fixing anything insanely difficult.

Any suggestions to point me in the right direction would be
appreciated... like I said I'm not sure if Django fits my needs in
this case.

I can't parse your question in the first sentence.  Code snippets might help.  
There is no content if you are getting a 302, it is a redirect and the only 
thing you can then examine would be the redirect Location.  Somehow the path 
your code is taking in response to a get on '/resultsdb/search_form/' is 
getting to a point where it returns a redirect, not a response.

You've also got another thread that I hadn't seen when I first responded on 
this one, where someone responded pointing out the likely line in your view you 
are hitting.  I gather from your last sentence you don't believe you can be 
hitting that line, but apparently you are. I couldn't get that far in reading 
the view code because it gets badly mangled in an email interface; dpaste.com 
would be a better place for putting code.

OK, so you've got an import that should work on Django 1.0.  I suspect
you're either not running on Django 1.0 (that import doesn't work on 0.96)
or your installation is corrupt.  The former is probably more likely.

At the expense of some additional complexity in your view & template, you
can maintain a one-step submission for your users.  I'd probably look at
adding an additional hidden input field to the form that starts out empty
but is used in cases where a file has already been uploaded through a prior
submission which failed validation for some non-filefield-related problem.
The value in the hidden field would allow the server view code to locate the
previously-uploaded file when the form is re-submitted.  The template would
display the File input field only when necessary, if a file has already been
uploaded then the template would display a note to that effect instead.

So if there are no errors on the initial submission, it's a one-step process
for the user.

If there is an error (not related to the uploaded file), the server stashes
the uploaded file somewhere and sets the value of the hidden field so that
the file can be found on resubmit.  From a user's point of view the form is
redisplayed but they do not have to re-select the file -- rather the form
shows that the file has been uploaded and the other error messages on the
form show what needs to be corrected to complete the submission.

On resubmit, the server locates the previously-uploaded file via the
information in the hidden field instead of getting it from the post data.
Your view logic is a bit more complicated than for simple forms, and your
template has to be a little more involved than {{ form.as_p }}, but it's
probably more intuitive for users than a 2-step default submission process.

This won't fix http://code.djangoproject.com/ticket/8906, but there's
at least one possible workaround in the meantime : use a sub domain
(ie subdomain.yourdomain.tld).

Re: FileField doesn't repopulate after a ValidationError on another field

[[EMAIL PROTECTED]]

Ok, this sounds logical to me.

I guess the best way to handle this is to make the uploading process
require 2 separate submission pages, the first one for all the regular
input, and then have a second page just to upload the file.

Perhaps somebody has a better idea?

Thanks

I can't parse your question in the first sentence.  Code snippets might
help.  There is no content if you are getting a 302, it is a redirect and
the only thing you can then examine would be the redirect Location.  Somehow
the path your code is taking in response to a get on
'/resultsdb/search_form/' is getting to a point where it returns a redirect,
not a response.

You've also got another thread that I hadn't seen when I first responded on
this one, where someone responded pointing out the likely line in your view
you are hitting.  I gather from your last sentence you don't believe you can
be hitting that line, but apparently you are. I couldn't get that far in
reading the view code because it gets badly mangled in an email interface;
dpaste.com would be a better place for putting code.

Well a 302 is a redirect, so it won't have content.  response['Location'] will 
tell you where it is redirecting to, which might give you a hint.

I believe this is a browser security measure.  The browser won't allow a
server to pre-load a value into a File input, because that would mean a
naive user could easily submit a form which uploads some key file from their
machine to the server.  So for a File input the browser requires that the
user actually go and select a file to upload.  (I do not know if there are
any tricks one can play to get around this, I've never looked for one.)

302 status code in django test client

[jeffhg58]

I am having difficulty trying to test out the content of the main
window because it returns the status code
of 302. Here is the snippet of my view. So, when I first call the
search_form the request falls out of the
if request. GET. Does anyone have an idea on how I can test the
content of this page?

Thanks,
Jeff

def search_form(request):



if request.GET:

global_vars.search_data = request.GET.copy()
form = SearchForm(global_vars.search_data) # Instantiate
and load POST data

if form.is_valid(): # Validate data
 page_num = search(global_vars.search_data)

 if request.has_key('getrecs'):

  rl = ResultList(request, page_num, 'Result')



  c = template.RequestContext(request, {
  'count': rl.result_count,
  'rl': rl,
  })
  renderfile = resultsdir + '/results_list.html'
  return render_to_response([renderfile],
context_instance=c)

 if request.has_key('getcsv'):
  # Create the HttpResponse object with the
appropriate CSV header.
  response = HttpResponse(mimetype='text/csv')
  response['Content-Disposition'] = 'attachment;
filename=somefilename.csv'

  qs = Result.objects.filter(**global_vars.query_dict)
  qs = qs.exclude(**global_vars.exclude_query_dict)


  writer = csv.writer(response)
  writer.writerow(['row 1', 'ID', 'Test Name',
'Project', 'Phase', 'Test Type', 'Station',
  'Start Date', 'Owner', 'Status',
'Test Configuration'])
  for i in range(len(qs)):
  rowtext = 'row ' + str(i+2)
  id = str(qs[i].id)
  tname = qs[i].TestName
  projname = str(qs[i].ProjectId)
  phase = str(qs[i].PhaseId)

  owner = qs[i].Owner
  status = str(qs[i].StatusId)
  configdata =
ConfigResult.objects.filter(ResultsId='%s' %qs[i].id)
  Configstr = ''
  for configresult in configdata:

  Configstr += ','
  Configstr += str(configresult)
  writer.writerow([rowtext, id, tname, projname,
phase, testtype, station,
  startdate, owner, status,
Configstr])



  return response
 if request.has_key('newresults'):
  #redirectaddr = resultsdir + '/newresults/'
  return HttpResponseRedirect('/resultsdb/newresults')

else:

I added the directory (project.app.modeldir) to the INSTALLED_APPS apps
and then the permissions are created. Problem solved.

302 is redirect. There is no content.

I found out that the syncdb command didn't work. I deleted a table and
after i did the syncdb, the table wasn't created.

It's because i've put the models.py file in a subdirectory. Because it
doesn't live in the applications main directory, it's not detected.
When i move the models.py file out of that subdirectory, the table is
created again and the permissions are added.

Now i need to find out how i can make the syndb command aware of the
models in that subdirectory. Can i trigger this from the __init__.py
file that lives in the main application directory?

You need to provide some templates in order to display the feed items  
as you want them to look, check out the documentation here:

You can return a queryset directly here, all you need is:

I do not know if this will work for Japanese Windows, but for the English
version, the two things I have found that need to be done to ensure a
command prompt properly displays utf-8
are first:

chcp 65001

in the command prompt to change the active code page to the one that works
for utf-8 (65001 is apparently Windows' spelling of utf-8) and second change
the font properties of the command prompt (left click upper left corner of
the window, choose Properties, then Font tab) to use Lucida Console, not
Raster Fonts.  If I do those two things then utf-8 data looks correct in my
command prompts.

FileField doesn't repopulate after a ValidationError on another field

[[EMAIL PROTECTED]]

Hello,

I've having a problem with FileField and ImageField. Basically, I have
a form for uploading images:

Name: _a_  (throws ValidationError('This name is already taken. Choose
another'))
Notes: _test notes_
Filename:  _abc123.txt_

When I press SUBMIT, I get the form again, but it looks like this:

-This name is already taken. Choose another
Name: _a_
Notes: _test notes_
Filename:  _ (blank Not sure why)

The FileField is not repopulated for some reason, but the other fields
are.

Using django-1.0

I bind the data as specified at
http://docs.djangoproject.com/en/dev/topics/http/file-uploads/#topics-file-uploads:

form = UploadNewImageForm(request.POST, request.FILES)

My view function is identical to the one on the example page.
Everything else works, the file is properly uploaded and there are no
other problems. It is really just a user interface issue I would like
to fix because it is very annoying to have to repopulate the form
every time there is an input error, especially if there are many
fields.

Blank content from unit testing

[jeffhg58]

I am currently the django test client and I have run across a
stumbling block.

When I do a get command for my main screen which is get('/resultsdb/
search_form/'), the status code
returns a 302 with no content.
But, if a do a get on say ('/login/') or a subsequent window besides
the main window such as ('/resultsdb/newresults/') and get a status
code of 200 with the content of the window.

Any help would be greatly appreciated. I am stumped on this.

Thanks,

You'll need a JVM - Python doesn't speak Java!

You can either just use the Subprocess module to call the JVM, just as
you would from the command line, or you might perhaps take a look at
 or .

Take a look at Python's subprocess module which lets you execute other

This may or may not be your problem, but I am keeping all of my 
applications out of \program files.  It is my understanding that this is 
now reserved for "works with Vista" applications.  I install everything 
in \users\public.  So I would install PostgreSQL in 
\users\public\postgresql.  I also put my apps in something like 
\users\public\myapps.

I am sure you can find other recommendations for postgresql.

can't delete many-to-many related record from admin inline

[chris]

Hi there,

I am still pretty new to django and just trying to figure out how it
is all supposed to work.

I have the following models:

*models.py:

class Char(models.Model):
char = models.CharField(max_length=10)
variants = models.ManyToManyField("self", symmetrical=False,
through="Variant", related_name="varchars", blank=True, null=True)

class Variant(models.Model):
 char = models.ForeignKey(Char)
 variant = models.ForeignKey(Char, related_name="vars")

*admin.py:

class CharVarInline(admin.StackedInline):
  model = Variant
  fk_name = "char"
  raw_id_fields=("variant", "char",)
  extra = 1

class CharAdmin(admin.ModelAdmin):
inlines = (CharVarInline,)


This causes the variants part to be displayed with a char record in
admin.  I also get a check-box there, which can be checked to delete
the inlined related recorded.   However, when I try to used this to
delete the record and click save, the following error occurs:

ValueError at /admin/chardb/char/70524/

'Variant' instance needs to have a primary key value before a many-to-
many relationship can be used.

Apparently, something is going wrong with the deletion, which lets
part of the record hang in empty air.  But I have no idea where to
look or how to fix this.  Does anybody has any idea?

Any help appreciated,

Chris

inspect a model's field's option's values

[Mark Wolgemuth]

It seems like I'm missing something, but here's what I'm trying to do:

In creating a Form object, I'm setting size limit validation
(max_length). I'd like to recover the value for that from the
corresponding Model's Field's max_length. So basically I want a symbol
lookup that will inspect in the options of a field I have defined for
a model, without having an instance of the model, just it's type.

This is to avoid the 2 having to share a common separately defined
constant, or just using an integer that I have to coordinate in both
places, or in place of always using auto forms.

eg

class MyModel(Model):
 myfield = CharField(max_length=128)

--

class MyForm(Form):
 myfield = CharField(max_length=**GET.FROM.MODEL**)

I assume that by using the Meta:  model = logic in Form for auto form,
that this is being done, but it wasn't obvious to me how.

geodjango on cough-vista-cough?

[7timesTom]

I'm trying to install geodjango on windows vista business (I know!
sorry!). Firstly is this a futile attempt to begin with?

If not, here's the problem I'm getting:

I've installed PostgreSQL using the windows xp instructions at
http://geodjango.org/docs/install.html#windows. And then done a full
install of all available pgSQL options. But when I come to install
PostGIS I get the error:

"""PostGIS 1.3.3 for PostgresSQL 8.3

Error opening file for writing:

C:\Program Files\PostgreSQL\8.3\bin\libgeos-3-0-0.dll

[Abort] [Retry] [Ignore]"""

And indeed that file and others (libgeos_c-1.dll, libiconv-2.dll,
libproj.dll, pgsql2shp.exe, shp2pgsql.exe, etc etc) mentioned if I
click ignore are indeed missing.

Does anyone know if they are supposed to come with PostgreSQL 8.3 and
which component I may be missing?

Many thanks.

This is actually incorrect (open a ticket as a reminder and I'll fix
the docs); by default, the admin now uses the default manager for the
model, same as everything else in Django.

As to your original question, ModelAdmin has a method named
'queryset()', which is used to obtain the QuerySet of objects for
display in the admin lists and for looking up objects to edit.
Overriding that method on your ModelAdmin subclass is the correct way
to do this.

This method receives the incoming HTTP request as an argument, so you
can use it to filter based on some attribute of the request (e.g., the
logged-in user). This also means that when overriding, you must define
the method as "def queryset(self, request)", not just "def
queryset(self)".

Re: changing the Manager the admin-site should use

[Dennis Schmidt]

Well that does work, though in the Manager documentation it's said:

"If you use custom Manager objects, take note that the first Manager
Django encounters (in the order in which they're defined in the model)
has a special status. Django interprets this first Manager defined in
a class as the "default" Manager, and several parts of Django (though
not the admin application) will use that Manager exclusively for that
model."

Which I understand as "Everything in django uses the first manager,
but the admin uses objects".
The thing is that I'm a bit curious about changing the default
manager. How shall I know this won't raise Exceptions anywhere in the
django code if my Manager behaves differently from "objects"?

mod_python calls an older script?

[Alessandro]

I'm getting weird errors about a script that I've changed recently (a
template_tag).
It's strange because it refers to a line that I've deleted, so I think
it comes from some cache, but I cannot find nothing.

the pyc file is no more compiled, so the directory with that files has
only a .py.

Where can I search for mod_python or django cached compiled scripts?

Thanks in advance!

The problem seems to be that your filter function doesn't mark itself
with an is_safe attribute (defaulting it to False). So try marking
your filter with is_safe=True which means that your filter doesn't
introduce any HTML unsafe characters by itself (not including the ones
that are already in the input):

filterxx.is_safe = True

Also, it's easier for people to follow a discussion thread if you
don't top post your responses.

custom auth

[Gabriel Rossetti]

Hello everyone,

I'm trying to get a custom auth handler to work but I keep on getting 
this error when accessing request.user.get_profile() :

DoesNotExist: User matching query does not exist.

I followed the following tutorials :

http://garage.pimentech.net/mdm_src_dj_auth_documentation/
http://www.b-list.org/weblog/2006/jun/06/django-tips-extending-user-model/

Here is my auth handler :

from proj.app.models import User as MyUser
from django.contrib.auth.models import User, check_password

def authenticate(self, username=None, password=None):
try:
myUser = MyUser.objects.get(email=username)
except MyUser.DoesNotExist:
return None
pwdValid = check_password(password, myUser.password)
if(pwdValid):
try:
user = User.objects.get(username=username)
except User.DoesNotExist:
user = User(username=username,
email=username,
first_name=myUser.firstName,
last_name=myUser.lastName,
password="none")
user.is_staff = False
user.is_superuser = False
user.save()
myUser.user = user # Not sure if this is really needed, 
I tried it since it didn't work and it still doesn't
myUser.save() # Not sure if this is really needed, I 
tried it since it didn't work and it still doesn't
return user
return None

def get_user(self, userId):
try:
return User.objects.get(pk=userId)
except User.DoesNotExist:
return None

here is my model :

from django.db import models
from django.contrib.auth.models import User as DjangoUser

class User(models.Model):
id = models.AutoField(primary_key=True)
firstname = models.CharField(maxlength=20)
lastname = models.CharField(maxlength=20)
email = models.CharField(maxlength=50)
password = models.CharField(maxlength=20)
user = models.ForeignKey(DjangoUser, unique=True)
#user = models.OneToOneField(DjangoUser, core=True) # This doesn't 
work either

I really don't see why it doesn't work...does anyone have a clue?

Thank you,
Gabriel

PS I've already looked at past posts on the subject but the common 
answer is to create the profile, but in my case it's already created, 
maybe I'm linking it wrong?

As far as I know, the admin site uses the first manager not necessarily 
the one called objects.
If you do set a none default manager, be sure to also set an objects 
manager, since django won't create the objects manager if it already 
finds a different manager.

Are you declaring the encoding of your source file?

Try putting

# -*- coding: UTF-8 -*-

at the top of your file.

Correction: the "Content-Disposition" header is fine, but you do need to
write the file contents to the response.

Re: Problem with pyExcelerator and response

[Steve Holden]

I suspect the issue is the response you are returning. I have never seen
attachments on HTTP responses: can't you just return the contents of the
"output.xls" file by writing it to response before returning it? You
would also need to remove the "Content-Disposition" header.

Just a thought.

regards
 Steve

Re: content type

[redmonkey]

You need to set a 'Content-Disposition' header.

http://docs.djangoproject.com/en/dev/howto/outputting-pdf/?from=olddocs#complex-pdfs

Look within the 'some_view' definition. You need to generate a
HttpResponse object, set the response mimetype to the correct type of
file you're serving, and then set the 'Content-Disposition' key to
something like it says. Notice you can also set the filename if you
need to.

Re: Help to Upload image

[Giles Thomas]

please smile wrote:
> Can anybody please tell how to upload a image ?

I'm new to this myself, but I got something working using Django's forms 
mechanism.

My view function looks something like this:

---
class MyForm(ModelForm):
class Meta:
model = photos

def upload(request):
if request.method == "POST":
form = MyForm(request.POST, request.FILES)
if form.is_valid():
sheet = form.save()
return HttpResponseRedirect(reverse('upload_thanks'))

return render_to_response(
"upload.html",
{
"form" : MyForm(),
}
)
---

This is then rendered by a template, upload.html, that looks something 
like this:

---

  
{% for field in form %}
  



{{ field.errors }}

  
  

  {{ field.label_tag }}:


  {{ field }}

  
{% endfor %}
  

  

---

Finally, my urls.py specifies "names" for both the upload and the 
upload_thanks pages:

---
urlpatterns = patterns('',
# ...
url(
r'^upload/$',
'my.app.views.upload',
name="upload"
),
url(
r'^upload/thanks/$', 
'django.views.generic.simple.direct_to_template',
{ 'template' : 'upload_thanks.html' },
name="upload_thanks"
),
)
---

Hope this helps.


Cheers,

Giles

Hi,
i hope any one can help me.
I want to generate a rss-feed.
The url ist http://localhost:8000/isf/info/.
All works fine but the title of an Item and the Description are still
the same!
How can i change the title of an feed item in the feed to the title
from the model
and the description of the feed item to the description from the
model.
I get only the String from the __unicode__(self): Method. An this
string represent
the title and the description, why ?

Please help me!



My urls.py config:
feeds = {
'rss': Rss2Feed,

}

urlpatterns = patterns('django.contrib.syndication.views',
url(r'^(?P.*)/$', 'feed', {'feed_dict': feeds},
name="fh_feeds",),
)

Thats my models.py class:

class Item(models.Model):
title = models.CharField(max_length=30)
banner = models.CharField(max_length=30, null=True)
description = models.TextField(null=True)
pub_date = models.DateTimeField(auto_now=True,
verbose_name="Public Date")
expire_date = models.DateTimeField(verbose_name="Expire Date")
author = models.ForeignKey(User, editable=False)

def authors_email(self):
return "%s"%(self.author.email)

def get_absolute_url(self):
return "%s/"%(self.id)

def __unicode__(self):
return self.title

class Meta:
ordering = ['-pub_date']

class Item_Category(models.Model):
item = models.ForeignKey(Item)
category = models.ForeignKey(Category)

def __unicode__(self):
return "%s"%self.item.id

And thats my feed.py class:

class Rss2Feed(Feed):
#thats my hard-coded title,link and description for my info feed
title = "Info"
link = "/info/"
description = "Info-Site"

# i want to show all items of my model with the slug info
def items(self):
listOfItems = []
itemToCategoryForInfo =
Item_Category.objects.select_related().filter(category__slug = "info")

Re: How to get site's root path in Django

hi, Karen, Thanks for your reply.
I am sure I hit that problem, http://code.djangoproject.com/ticket/8906

For now, I would just include root path in LOGIN_URL and LOGOUT_URL

Decimal * Decimal

[Matthew Talbert]

I am having the problem discussed in this thread:
http://groups.google.com/group/django-users/browse_thread/thread/91aa6c088f6c090/929f2fd69307cd22?pli=1
as well as this one:
http://groups.google.com/group/django-developers/browse_thread/thread/63046b2fca27673c/898dbf8da327ce71

and I was curious to know if there has been any progress with this, or
if the solution is still either run in separate processes, or patch
and compile my own version of psycopg2.

Thanks
Matthew

I might note that there is currently no bug tracker for psycopg, so
I'm unaware of any way to check on the problem upstream.

you can use django.http.urlencode() to create the part behind the

If you want to pass a list in a value you need urlencode(..., True).

Re: Migrate app from MySQL to PostgreSQL

[Brot]

This doesn't work as expected. I tried the migration with dumpdata
month ago.
The problem is, that mysql and postgres writes another, incompatible
boolean values. I believe sqlite and postgres has the same problem!
I reworked the dumpdata output-file. In my case this was possible,
because the amount of data was not too big

__unicode__() method not working in models.py

[Andrew]

I am currently working through the django book and I've got to the
fifth chapter where I would like to replace the __str__() methods with
__unicode__() methods instead. The reason is that my database will
hold a great deal of Japanese text, UTF-8 encoded. After declaring the
UTF-8 encoding at the top of models.py, as a test, I replace

def __str__(self):
return self.name

with

def __unicode__(self):
return u'テスト'

Entering the following code (from the django book) into the manage.py
shell doesn't give the expected output.

>>> from books.models import Publisher
>>> publisher_list = Publisher.objects.all()
>>> publisher_list

I expect:

[, ]

but instead, the テスト part is replaced with random Japanese characters
that are not the ones I expected.

I am using a Japanese version of Windows XP with PostgreSQL installed.
The encoding of the database and the file are both UTF-8. The cmd.exe
prompt doesn't let me type in Japanese but it does display Japanese if
I print out something I've saved in a file for example.

Any ideas on where I'm going wrong? Apologies if this has been asked
before.
