Probably better to go to:

  http://groups.google.com/group/modwsgi

and post question there as sounds more specific to mod_wsgi than
Django.

Ensure that you have first tried simple hello world example from
mod_wsgi configuration guidelines:

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

If using daemon mode, run same example in daemon mode as well to make
sure that works before even attempting to set up Django.

Also look at:

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

Especially take note of shared library conflicts described in that
document.

Make sure you have set Apache LogLevel directive to 'debug' to capture
as much log output as possible so you can provide information when
requested.

The official mod_wsgi/Django documentation is actually at:

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

Even then, there can be more to it than that depending on how you are
trying to set it up.

In going to other list, make sure you provide as much information as
possible, such as mod_wsgi version, Apache configuration for setting
up mod_wsgi that you used, relevant messages from Apache error log
from time of restart up to and including the request you made.

Why wouldn't you be able to? It's just a SQLite database; as long as
you have the right version of the client library, what sort of problem

not really a django problem, just fishing here--

[Jason Witherspoon]

Hey everyone--

I've been trying to run Xapian alongside my Django app for lo, many  
moons now.

Here's the problem I run into:  Xapian is compiled to work w/a Python  
that's been configured for ucs4 support (this is a manner of handling  
unicode).  Won't work w/ucs2, far as I can tell.

When I try recompiling my Python to work w/Xapian, it breaks my  
psycopg2, which was compiled for ucs2 support.

Okay, no problem, I blitz every instance/egg of psycopg2 & install it  
fresh on top of my new ucs4-compliant Python.

Which lends some bizarre results-- in my best-case scenario (after  
several days of trial & error), I could get the psycopg2 module to  
load fine from IDLE, but it nonetheless still yielded non-stop  
"undefined symbol: PyUnicodeUCS4_[whatever]" errors when I tried to  
access my Django setup.

The only place I can find these PyUnicodeUCS[2/4] modules/whatevers  
(?) is in Jython, so I clean installed that for the heck of it.  No  
dice.

Anyone run across anything like this?  After some hairiness I've  
successfully returned to a working Python ucs2 configuration.  And  
I've asked on Xapian-discuss if a usc2-build exists, which would  
solve the problem nicely.  And wouldn't it be nice if Python just  
handled both ucs2 & ucs4, depending on what was required?  Yeah, I  
know, dream on

Any help much appreciated, and I actually know a lot more about this  
stuff than I'd prefer to now, so if this sounds comparable to a  
problem you've been having feel free to hit me backchannel & I can  
share what I know

a better DateTime widget

[James Turk]

I was wondering if anyone had experience with building a better
DateTimeWidget, I've built my own and am looking to clean it up and
make it available to the general public perhaps with some advanced
formatting options.

Are there any DateTimeWidgets in common use that use selects instead
of a text field?

Would this be useful to others, also do you think this is something
that could perhaps be contributed back into django?

To clarify on this comment. Each of the 'clients' does not fire up a
Python VM.

The Python framework as a whole is initialised only once per Apache
child process. This initialisation as a side effect will always create
the main Python interpreter instance for the Apache child process.

Unless you use PythonInterpreter directive to force site to always run
in the main Python interpreter instance, then by default an additional
Python sub interpreter instance will be created per virtual host. The
per virtual host sub interpreter instance will be created the first
time a request to mod_python for that virtual host is received.

When any interpreter instance is created within an Apache child
process, that interpreter instance will then persist for the life of
that process and will be used in handling all requests which map to
that interpreter instance.

A Python interpreter instance when first created and before any web
application is loaded should only add a few hundred kilobytes,
although mod_python adds on top of that with its dispatch code, it is
not tens of MBs though. Thus to say that 'Python VM taking up several
tens of MB of RAM' isn't accurate. If you are seeing this sort of
memory usage from just loading mod_python, then you have a Python
installation which doesn't provide a shared library for Python and
which also may include debug symbols.

Now, when a Django site instance is loaded, typically this can add
about 5MB per process. This value will increase over time based on
your application and how it uses memory based on database queries and
internal operations. Yes this can get up to tens of MBs, but that is
from the Django application and not mod_python or Python itself.

> Even if each

This can be a problem if using prefork, so dropping max clients to a
level more realistic for the amount of memory available is a good
idea. If memory is still an issue, then validating that your
particular Django application is thread safe would be worthwhile and
switch to worker MPM for Apache instead.

Although worker MPM uses multithreading, claims that the GIL would be
a problem is not the big issue some would say it is. This is because
Apache is a multiprocess web server so there is no restriction on
making good use of multiple processes and cores.

As far as memory overhead goes, mod_wsgi uses less base level memory
than mod_python. The per request overhead of mod_wsgi is also less
than mod_python, so if you really wanted to squeeze as much as
possible out of what you got, mod_wsgi should be better. That said,
realistically though the bottlenecks appear to be in the application

Re: Custom model fields not working?

[[EMAIL PROTECTED]]

OK, well now, for some reason whenever I use a custom field Django
just ignores it when running syncdb. If I ask it for the raw SQL
output I can see that the field is being omitted entirely. Even if I
do something simple like:

class TestField(models.TextField):
 pass

Does anyone know what I am doing wrong?

Country, State and City data

[weissblitz]

I'm building a django site that requires the user to select their
geographical location.

Does anyone knows where can I get this country/state/city data in a
format that can be imported into MySQL?

Thanks in advance,

Your problem is that you're importing the PickledObjectField into your
class's namespace. So when Django processes your form definition, it's
actually getting two attributes:

* lookups (instantiated, which will work fine)
* PickledObjectField (uninstantiated, which will cause errors)

Move the import statement to the top of your models.py file, where it
belongs, and you should find that the error goes away.

There are no doubt other things you'll run into, but I'll at least
give you a chance to work them out on your own. :)

Re: about tagging app and tags cloud

I'm controling the font size with CSS, that is not the problem, the
problem is with the code for tags cloud that it doesn't generate the
font_size attr for some tags.

Custom model fields not working?

[[EMAIL PROTECTED]]

Hey everyone,

I've asked a little in the Django IRC, but nobody seems to be able to
help. I'm trying to implement a custom model field, and I really can't
figure out why I keep getting errors. My code for my fields module is
at http://dpaste.com/hold/27712/

When I try to run syncdb on a model which uses the PickledObjectField
(see my sample model at http://dpaste.com/hold/27713/), I get this
traceback:-

RSS...my parameters are not correct

[Greg]

Hello,
I'm trying to get my RSS feed items to link to the right url, however
I'm having trouble.  I was orginally having my blogs appear in my RSS
feed.  When I clicked on one of them I would get the error:

' Invalid feed parameters. Slug u'latest' is valid, but other
parameters, or lack thereof, are not. '

However, after changing some of my code my blog entries are not even
showing up in my RSS feed.  Here is what I have so far.



urls.py

from mysite.app.models import LatestEntries, LatestEntriesByCategory

feeds = {
'latest': LatestEntries,
'categories': LatestEntriesByCategory,
}

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

///

models.py

from django.contrib.syndication.feeds import Feed

class LatestEntries(Feed):
title = "MySite.com News"
link = "Not Sure what goes here"
description = "Updates on changes and additions to Mysite.com."

class LatestEntriesByCategory(Feed):
def get_object(self, bits):
if len(bits) < 1:
raise ObjectDoesNotExist
return Blog.objects.get(slug=bits[-1])

def title(self, obj):
return "My blog for %s" % obj.name

about tagging app and tags cloud

[Lic. José M. Rodriguez Bacallao]

hi folks, I need to generate a tags cloud for a model and I'm using
the tagging app from google code. I do something like this:

cloud = Tag.objects.cloud_for_model(NewsEntry, 6)

and generate the html cloud based in the "font_size" attr from the
tags list "cloud". The problem come when I realize that some of the
tags in that list (cloud) doesn't contain a "font_size" attr> I was
looking inside the code of the tagging app and I saw that when the
"count" attr of the tag is less than any of the values of threshold
list it doesn't add the "font_size" attr, so, how can I generate the
tags cloud?

Just a possibility:

If you're launching huge numbers of requests, but all from the same
machine (e.g., the one running ab), your request-generating machine
may be saturating its own bandwidth, which could cause Apache
processes on the web nodes to stall as they wait for you to be able to
receive data, which in turn leads to requests piling up and increased
load on the web node (but not on the DB node, which doesn't notice
anything unusual).

Not saying that's necessarily what's happening, but it's something to
look into. Also, 300 req./sec. for something you apparently haven't
done much profiling on is pretty damned impressive in my book.

Again I suggest a hello-world view as a baseline, but if you really
are doing 7000 queries per second, perhaps you're also constructing a
lot of ORM objects; there's some overhead to the signalling (pre/post
init, pre/post save).

DB handling 7000 selects/sec while web server is serving 300 pages/sec
implies each page request is generating >20 select requests.  Does that seem
reasonable to you based on the content of the page you are serving?  (It
seems high to me.)  Brian Morton provided a pointer to the doc for
select_related, which could help to reduce the number of selects.  Even if
the database is keeping up, so many round-trips talking to it for a single
page request is going to add up.

I think a large part of my question really comes down to "Is 300 
requests per second reasonable for an uncached django site on a single 
machine?".  Maybe it is.

We are looking at using the memcached API in our code, and I'm sure we 
will get a speedup there.  But before we start down that route, I wanted 
to make sure we weren't doing any silly on the raw site.

I think my next step is to use the profiler and find out why the site is 
so CPU intensive.

Thanks for all the help.

Accessing Multiple Databases

[Derek Steinkamp]

I read through all the relevant documentation but I couldn't find any 
info on an issue I am about to face: accessing multiple tables in 
different databases with Django.

Here's a quick example:
My Django app (MyApp) has r/w access to the MyApp database on 
MySQLserver1, and all of MyApp models live within here. I now need to 
access a pre-existing database/table on MySQLserver2 to bring in some 
data relevant to MyApp.

My ultimate question is: does Django support accessing models that live 
in/on different databases/servers within one app? If so, how do I do 
this? If not, what should I be doing?

Thanks,
Derek

Please make  'hello world' view to simplify the troubleshooting.

If it's still "only" 300 r/s without hitting the DB, the problem is
much smaller.

You haven't listed your ab parameters; if you're using maxclients so
high, perhaps you're paying the process startup cost (nearly) each
time, so consider setting startservers high.  In general, if you have
a dedicated web server, setting startservers near maxclients isn't a
bad way to go.

Admin

[Goldy]

I have a table ending in 'ery', however in the admin it is spelt 'ys',
if course this is wrong it should end in 'ies'.
Is it possible to change this?

No, I don't need anything added, I'm just slow and didn't see the link

What do you want in addition to the official docs?
http://www.djangoproject.com/documentation/modelforms/ If there's
somethings specific that *isn't* covered, just ask on django-users.

Please don't post questions to the developer list though. Most of us
read django-users as well, and that's where questions belong. The
developer list is for discussing the development of Django itself.

The machine is definitely not swapping.  It has 16 gig of ram, and top 
never shows more than 7 gig of ram in use when I do the load testing.

I have maxclients set to 1000, but the number of apache processes never 
gets close to that value.  I've played around with various settings for 
maxclient, but as long as I don't set it too low, this never comes into 
play.

I'm not all that qualified to comment as I've never done this sort of testing,
but I do wonder if the performance you are seeing may not be all that
unreasonable, given that no caching is currently being performed?  Using
memcached has been known to improve performance dramatically.

Profiling never hurts, but there's nothing wrong with doing the easy stuff
first, right?

Hi again,

Apart from Joe's excellent profiling suggestion, I would recommend
reducing maxclients to a much lower value (like say 100) and then
increasing it gradually.

>From your description of the sluggish response of your web server, it
looks like the machine may be swapping to disk. Each of your clients

Re: using FileField.delete_file to remove unused images

[Marty Alchin]

There are several things you need to know, so I'll lay them out.

1) You can get any Field instance from a class by using the
model._meta.get_field() method. Instead of your list comprehension,
just use the following line:

picfield = p._meta.get_field('picture')

2) If you read the comments in delete_file(), you'll see the
following: "If the file exists and no other object of this type
references it, delete it from the filesystem." Your problem is that
the Person "p" still references the file, so delete_file() won't
delete it. You'd need to put something like this before the
delete_file() call in order to get it to work properly:

p.picture = ''
p.save()

3) Saving an object with a new filename alters the corresponding field
in the database record. What this means is that you can somewhat
ignore the previous item, and simply put delete_file() at the *end* of
your script, instead of before the file saving code. That way, by the
time it runs, the Person "p" will already have a different filename,
and delete_file() won't find it, and will happily delete the file for
you.

4) save_FOO_file() automatically saves the model instance with the new
filename. Right now, you're calling p.save() after
p.save_picture_file(), which results in two hits to the database for
absolutely no reason. save_picture_file() calls save() internally, so
don't bother doing it again.

5) With those changes, your code should look something like this:

class PersonForm(forms.Form):
# ...
picture = forms.ImageField(required=False)
# ...
def save(self):
# ...
p = Person.objects.get(pk=pk)
file, content = (self.cleaned_data['picture'].filename,
self.cleaned_data['picture'].content)

p.save_picture_file(file, content)
p._meta.get_field('picture').delete_file(p)

6) Deleting files will get much easier soon, and it will even be a bit
simpler to do what you're looking to do, without having to build all
this into your form logic. So most of the things I've just covered
will change, but for the better.

Re: Performance of a django website

[Brian Morton]

Joseph raises a good point.  I only recently discovered what a
performance killer DEBUG mode can be when it comes to queries.  It
will cause your client machine (the web server in this case) to run
out of memory after a lengthy process (such as data loading).  Are you
profiling in DEBUG mode?

Actually, there is. The related manager created by Django uses your
custom manager as its base class. You can exploit that fact in the
custom manager for your child object. Something like this should do
the trick:

class FooManager(models.Manager):
def get_query_set(self):
base_queryset = super(FooManager, self).get_query_set()
if "related.RelatedManager" in str(self.__class__):
# We were called through our Parent's related set
ordered_query = base_queryset.order_by('number')
else:
# We were called directly
ordered_query = base_queryset.order_by('title')
return ordered_query

And, of course, add "objects = FooManager()" to the Foo class.

Re: Performance of a django website

[Joseph Heck]

Definitely take that specific dynamic page and profile it - see what's
happening and why its slow. That's clearly your first bottleneck to
work on from the data you've provided.

There's a wiki page on that very process here:
http://code.djangoproject.com/wiki/ProfilingDjango and there's
additionally some information you can get when you enable DEBUG to see
how long the SQL queries are taking for that dynamic page. There's a
nice snippet to help there at
http://www.djangosnippets.org/snippets/93/

1. Static content and dynamic are on the same server (that will change 
on production).  But they are on different apache virtual.  Mod_python 
is turned off for the static stuff.  Hitting only a static page is very 
fast (6500 requests per second).  Hitting the dynamic side is slow (300 
requests per second).

2. It's gigE between the web server and mysql server, on a dedicated 
switch.  The database is working pretty hard (7000 selects per second), 
but doesn't seem to be the bottleneck.  The webserver is hammered 
(typing any command takes a long time).
3. I'm using prefork MPM on apache with maxclients set to 1000.

We are starting to experiment with caching, but I want to improve the 
raw performance of the site as well.

Re: Performance of a django website

[Brian Morton]

Are you serving static content from the same apache instance?  Also,
what kind of network connectivity do you have between your web and
mysql servers?  It sounds like apache might need some tuning in terms
of thread parameters.  Have you enabled caching yet?  Turn on the
cache framework site-wide and set your expiration period to 1 minute
or something like that.  You can go back and only enable it for views
that you want cached later.

Re: Performance of a django website

[Eric Walstad]

If you don't already use them:

Firebug:
http://www.getfirebug.com/
will show you how long each component of the page takes from request to 
response and shows you what components are returned in parallel (among 
other really cool features).  This can help identify your bottleneck. 
For example, if your images are taking longer than expected while the 
page itself returns quickly then you may want to serve images with a 
dedicated web server, like lighttpd.

Yahoo's 'yslow' tool gives your page a 'grade' and offers advice on how 
to improve your grade.  It also has other handy bits (JSLint, Empty vs. 
Primed cache comparisons).
http://developer.yahoo.com/yslow/

The grades are based on their 'Rules for High Performance Websites':
http://developer.yahoo.com/performance/index.html#rules

Hm, funny, their yslow page scores a 'D' :)

I forgot to mention these:

8. django template debugging turned off
9. apache maxclient cranked up to 1000 (although it never gets close to 
that many processes).

Re: Noob question: Which Linux distribution is "best" for Django?

[Joe]

To make things easy, you could download VMware Server - run that on

easy to try out a few linux versions. VMware is free as are the

Re: Performance of a django website

[Joe]

I've found the largest memory hog to be the native way related tables
are setup.

Check class definitions with related tables and edit as such:

class ...(models.Mode):
relatedtable= models.ForeignKey(RelatedTable, core=True,
raw_id_admin=True)

The raw_id_admin=True prevents django from pulling up all related
records when the object is loaded etc. While I would have expected
this to only affect the admin side, it had a huge impact on the public
side of our site. Memory consumption went from +500mb to 20-30mb.

Re: using FileField.delete_file to remove unused images

I didn't use delete_file, but if you can't solve this you can write
your own code for that using signals (pre_delete or post_delete).
More: http://code.djangoproject.com/wiki/Signals

Anyway I'm also curious how to do that without signals.

using FileField.delete_file to remove unused images

[ER Yost]

I am working on a project with the following:

class Person(models.Model):
# ...
picture = models.ImageField(...)

I'd like to give each Person the ability to delete images, and I'd
like to remove deleted pictures from the filesystem once a person has
deleted them. From what I can tell, the delete_file function in the
FileField class (http://code.djangoproject.com/browser/django/trunk/
django/db/models/fields/__init__.py, line 767) will do that for me.
However, I haven't gotten it to work. Here's a chunk of the code I'm
working with...

class PersonForm(forms.Form):
# ...
picture = forms.ImageField(required=False)
# ...
def save(self):
# ...
p = Person.objects.get(pk=pk)
file, content = (self.cleaned_data['picture'].filename,
self.cleaned_data['picture'].content)

# I'm most confused on how to get the instance of ImageField
class to operate on
# this is the best thing I could come up with
picfield = [f for f in p.__class__._meta.fields if f.name ==
'picture'][0]
picfield.delete_file(p)
p.save_picture_file(file, content)
p.save()
# return None

Django doesn't argue with the syntax, but it also won't delete the
file from the filesystem. My main assumptions are that:
delete_file accepts the instance of the model containing the
ImageField (in this example, Person)
I have the steps (get field, delete file, save new file, save
person instance) in the right order

Performance of a django website

[Richard Coleman]

At work, we are developing a commercial website based on Django.  It's a 
fairly dynamic site (think social networking).  I am doing the initial 
load testing to estimate the number of servers we will need for the 
production site.  The production site will be load balanced using a pair 
of BigIP boxes.

When I stress test the dynamic part of the site, I am only getting about 
300 requests per second on my test setup.  This is using two Dell 1950's 
(one for web, one for mysql database).  These are very powerful machines 
(3.0ghz Xeons, 8 cores each, 16 gig of ram, 15k SAS drives, etc.)

I've done all the standard performance tuning I find when reading 
through various websites about django tuning.  Is this the performance I 
should expect.

When I'm running the load test, the CPU on the web server gets 
completely buried (even with 8 cores).  The mysql server doesn't seem 
loaded at all.  Any suggestions on how to find the bottlenecks?

I'm running Ubuntu 7.10 (server, 64 bit version).  Django from a very 
recent trunk.

Thanks for any advice.

Re: Best way to make content in templates

Isn't it just putting variable into template? I don't know if I
understand you correctly but for example:

models.py

Image(models.Model)
name = CharField(...)
location = ImageField(...)

YourModel(models.Model)
image = ForeignKey(Image)
user = ForeignKey(User)

(...)

index.html:



views.py:

(...)
from django.template import RequestContext
def my_request_context():
my_model = MyModel.objects.get(user=request.user)
# you can get the Image : my_model.image
return my_model # or my_model.image

and then use it when you need (rememer to add it to
TEMPLATE_CONTEXT_PROCESSORS in settings, and to call the request
context everytime you need it in views in 'render_to_response')

But I don'f now if it is what you need.

You should focus on http://www.djangoproject.com/documentation/templates_python/

Best way to make content in templates

[[EMAIL PROTECTED]]

Hi folks,

I am new to Django and I want to know which is the best approach to
create content in templates for example:
- I need to call a logo image for the website, the logo location in
the system is referenced in a field of a model.

I want to display the logo by getting it from the system after
consulting the DB.

Can you tell me what's the best approach?

Thank you in advance.

You were going so well on the "good advice" front up until here... :-)

A __unicode__() method if one of the few places where smart_unicode() is
inappropriate. You should use force_unicode() if you need that function
(in the case at hand, we can save time and just call unicode() directly,
but that's beside the point here).

The reason for preferring/requiring force_unicode() here is if the thing
you are converting is a delayed translation --- something marked with
ugettext_lazy(), for example. The smart_unicode() method leaves a lazy
translation as a lazy translation object, whereas force_unicode() forces
the object to a unicode string. This is why you usually want to call
smart_unicode(): it won't prematurely convert lazy translations to their
string form. However, a __unicode__ method is one place where you
absolutely *must* return a string, not something that might grow up to
be a string one day. So you should use force_unicode() there.

All this is, of course, a moot point if you know the thing you're
converting isn't a lazy translation, which is often the case in a
model's __unicode__(), but it's a good habit to get into in any case.

Regards,
Malcolm

Re: just starting out with django along with the tutorial - getting a type error

[l5x]

I don't know if it could help, but anyway you should:

1) add the following line at the beggining of models.py

# -*- coding: utf8 -*-

2) change the order of stuff in models, at first fields: CharField
etc, then classes (Admin, Meta) and methods at the end (__unicode__
etc).
3) add after 'coding', at the beggining:

from django.utils.encoding import smart_unicode

3) on model Ticket:

def __unicode__(self):
return self.ticket_numb

change it to:

def __unicode__(self):
return smart_unicode(self.ticket_numb)

I suppose that's the reason. You are returning Integer (ticket_numb is
integer) in __unicode__ when django expects unicode string.

Hope it will help.

 Yes, after trying with inline options to no result, I've resolved too 
in using the fields instead of the form to have more granularity :


This is the template :


[..]
Password: {{ f_user.password }}
Clid: {{ f_customer.clid }}
[..]



And the view:

[..]
if request.method == 'POST':
user = User(username=request.POST['username'])
user.set_password(request.POST['password'])
user.save()
customer = CustomerProfile(user=user,
   clid=request.POST['clid'])
customer.save()
[..]


It's not that inelegant in the end ... probably it can get better with 
the fields meta-option of ModelForm

That error usually means you're trying to return something that isn't a
string from a __str__ or __unicode__ method. Sure enough ...

Since 'ticket_numb' is an integer, you cannot return it unadorned form
__unicode__. Return unicode(self.ticket_numb) instead.

just starting out with django along with the tutorial - getting a type error

[[EMAIL PROTECTED]]

Hi All,

I'm just starting out with django. I want to get familiar with it to
do some inhouse development for myself. I'm following along the
tutorial, but using my own data and examples - i'm trying to create a
very simple request-ticket system. I have got up to the admin
interface part of the tutorial, and i tried to use the admin interface
to add a ticket, but i got the following error:

Environment:

Exception Type: TypeError at /admin/trak/ticket/add/
Exception Value: coercing to Unicode: need string or buffer, int found



Here is a copy of my models.py file:

from django.db import models
import datetime

# Create your models here.
class Status(models.Model):
class Admin:
pass
name = models.CharField(max_length=100)
def __unicode__(self):
return self.name


class Submitter(models.Model):
class Admin:
pass
name = models.CharField(max_length=200)
email = models.EmailField()
def __unicode__(self):
return self.name

class Ticket(models.Model):
class Admin:
pass
def __unicode__(self):
return self.ticket_numb
def was_submitted_today(self):
return self.create_date.date() == datetime.date.today()
summary = models.TextField()
date_created = models.DateTimeField('date created')
status = models.ForeignKey(Status)
ticket_text = models.TextField()
submitter_name = models.ForeignKey(Submitter)
ticket_numb = models.IntegerField().

As soon as I fill in the form to add a  ticket and click the save
button, i get a django error. The funny thing is that it gets added to
the database:

mysql> select * from trak_ticket;
++-+-+---+-
+---+-+
| id | summary | date_created| status_id | ticket_text |
submitter_name_id | ticket_numb |
++-+-+---+-

|  5 | asdf| 2007-12-11 14:19:05 | 1 | asdf
| 1 |   1 |
++-+-+---+-
+---+-+

Whats up with it?

Re: cannot import ModelForm

[l5x]

Once again, you were right Malcolm.
Python was importing the old django version, so I did:
python setup.py install

in the trunk and now it's working.

Thank you everyone for your suggestions.

Ps. I'm really happy that ModelForm exists, it's very useful.

Re: parameters getting modified

[annacoder]

Hi,
 Thanks for the input.

 Its all because of my misunderstanding of how the URL is handled by
apache.
 Apache does not allow multiple slashes in the path portion of the
URL.
 (It seems there are some security underpinnings, which I did not
understand).
 And there seems to be no way to turn it off.

  My idea was to let someone do, www.xyz.com/post/URL,
 to take the user to a form preloaded with the URL (so the user can
just copy past the url he wants and put it in place of URL in the
above link).

 Since, this is not possible, I have resorted to,
 www.xyz.com/post/?URL, since in this case URL becomes part of the
parameter portion.

Thanks,
Venkat
