using adobe forms (fdf) to create PDF

[Sells, Fred]

Does anyone have experience doing this and can share a link or a snippet.

I've got a multi page PDF with editable fields, but I want to fill the whole 
thing in from my DB and then print it.

Thanks.

python threading admin actions weird problem

[rahul jain]

Hi there !

Some weird problem happening with admin actions.

My admin action create threads which access a shared variable.
Those threads change the state of the variable for ex

check = False (a boolean)

One of the thread sets it to True

At this time I am done with that entire request.

Now if I run the admin action again the state of the variable "check" is

check = True

which is not right. It should be

check = False since its a completely new request.

Its happening on both on development (django local server ) and
production (Apache server).

What could be the problem ?

That is the Apache access log file, not the Apache error log file.
Those values after HTTP status code are number of bytes returned.

This is all moot now as your original 403 error has long gone now
since you have it worked.

The error in Apache error log corresponding to 403 might have been
something like:

  client denied by server configuration: /home/grumpy/example-1/
hello.wsgi

or:

  (13)Permission denied: access to / denied

as quoted in mod_wsgi talk slides (at bottom of error page shown by
browser).

which of those you got would have been clue to what was wrong way back
at that point.

Right now I figure you probably just hadn't restarted Apache after
making some change to Apache configuration and was only later when
making other changes and you restarted it, that picked up change.

Anyway, move on, as obviously have Django default page working now.

Re: Django comment moderation error: AlreadyModerated at /

[Ludovico Fischer]

I have encountered the same problem; the reason is that every time
models.py is imported Django attempts to register the moderator
another time.
You can do as suggested here:
http://stackoverflow.com/questions/3277474/django-comment-moderation-error-alreadymoderated-at
but it looks as if _registry is meant to be a private API.
The ideal way would be to put the registration somewhere where it is
going to be only executed once. The question is where?

Re: MultiPartParserError HTTP_CONTENT_LENGTH zero when uploading a file

[Eric Chamberlain]

In our case, I've tracked the problem to the client library we are using, 
ASIHTTPRequest.  The library is occasionally sending an incorrect 
Content-Length when configured to use persistent connections.

Re: Create files and directories from Django 1.2.1

Hi all,

I recently migrated from Django 1.1.1 to 1.2.1. In 1.1.1 I had an
application which imports an external python script in which a

work anymore, I get a number of IOErrors because the files (and
directory) that should be created can't be found. I've tried changing
my directories and slashes (I'm using Windows), but no success.


Have you changed anything else?

For example, are you processing the Microsoft Windows update patches 
which (for WinXP) insert extra permission steps? Have you changed your 
OS from XP to Win7?


Can you post the source of the script?



Can't I use the os python functions anymore in Django 1.2.1? In the
documentation I've read about Managing files in models but I prefer to
handle this through my external script.

I hope anybody can help me.

Thanks,

Re: AttributeError for ModelForm

[vikalp sahni]

As you are using Multi Table Inheritance,

Django docs says you should give "related_name" attribute to all your sub
classes fields
where relation is tried to establish.

You can try changing ur Question Model to:


 class Question(QItem):
   answerObject = models.OneToOneField("AnswerObject",
blank=True, null=True,related_name="ques")

Hope it works. Just a primary thought by looking on ur code.

Long running process and time outs?

[ydjango]

I have a online user initiated synchronous process which runs anywhere
between 1-5 minutes and gives user status message at the end. It is a
very DB intensive process that reads and updates lots of mysql rows
and does many calculations. The process is run as part of a view
method.

It causes nginx to time out after 2-3 minutes with following message -
"upstream timed out (110: Connection timed out) while reading response
header from upstream".  User sees  504 gateway error on his browser.

1) How can I prevent time out. Can I ping the server via ajax or
something to prevent time out.
2) How can I display to user - progress bar or in progress indicator -
so that user can wait 3 - 5 minutes.

Thank you for your hint, I solved by following this :

stackoverflow.com/questions/1471909/django-model-delete-not-triggered
I lost the confirmation page but I can live without it.

I also tried with pre_delete signal but raising an exception will display
500 error page and I couldn't find a way to redisplay the change_list
template with a nice message.

Re: django queryset get only one result for one column pair

[Rohan Jain]

My models are defined like this:

question = models.TextField('Question')

class Submission(models.Model):
user = models.ForeignKey(User)
problem = models.ForeignKey(Problem)

I want to run a sql command on submission field and get the list of

Re: new Django-Python can't get to sqlite

[jose antunes]

I have recently had the same issue. The problem was a python sqlite3 library
missing, by the name "_sqlite3.so". If that is missing it wont work. It can
be found if present in the python directory, under the lib_dynload/
directory.
 Like this for exemple: /usr/lib/python26/lib_dynload/_sqlite3.so
One way to solve this, is to install Python from source, after sqlite3 is
installed. The library will be automatically created and installed.
good luck!

Re: django queryset get only one result for one column pair

[Nick]

http://docs.djangoproject.com/en/dev/ref/models/querysets/#distinct

Distinct() may be what you're looking for to returns distinct values
for each problem.

Or, petter yet, you could use .latest()

So Submission.objects.all().latest('problem').distinct()

Create files and directories from Django 1.2.1

[Mark Mooij]

Hi all,

I recently migrated from Django 1.1.1 to 1.2.1. In 1.1.1 I had an
application which imports an external python script in which a
directory and some files are created. Since the migrate this doesn't
work anymore, I get a number of IOErrors because the files (and
directory) that should be created can't be found. I've tried changing
my directories and slashes (I'm using Windows), but no success.

Can't I use the os python functions anymore in Django 1.2.1? In the
documentation I've read about Managing files in models but I prefer to
handle this through my external script.

I hope anybody can help me.

Thanks,
Mark

Re: django queryset get only one result for one column pair

[Rohan Jain]

Actually there may be many submissions with a user-problem pair but i
want to list only the last one per user - problem pair.
Like:

let p1 be two problems , u1, u2 be two users and s1,s2 two submissions
by user u1 on problem and s3,s4 by u2.

so i want to get a queryset with only the last submission by u1,u2 on
p1.

That compatibility problem (Sphinx 1.0 and 1.0.1 were releases after Django 1.2)
wea fixed on Django trunk and on the 1.2.x branch so the fix will be
included with the 1.2.2 release.

Meanwhile I think you can fix you problem in two ways, either

1. Overwrite you docs/_ext/djangodocs.py with this file

   
http://code.djangoproject.com/svn/django/branches/releases/1.2.X/docs/_ext/djangodocs.py

2. or downgrade your Sphinx installation to 0.6.x (0.6.6 is the latest ATM).

...an retry building the docs.

We still have some incompatibility details when using Sphinx 1.0.x (one because
of further fixes needed on the Django docs and one that are waiting for some
fixes on Sphinx once the 1.0 dust settles, neither of them prevents you building
the docs like the problem you are experimenting now but they cripple
a bit the links between documents), see Django tickets  [1]14033 and
[2]14085.

So you might prefer to use option 2 for now.

The docs [0] mention an incompatibility with the currently released
Sphinx. I can't build right now either, and I'm too lazy to install
Sphinx from source.

Re: Loop over a form's choices (radio button) and render it

[Andreas Pfrengle]

Hello Bill,

thanks for your answer. However, I've never written a template filter
yet. Would you present the code of your checkboxiterator? Is there
sth. on djangosnippets?

AttributeError for ModelForm

[jcage]

I'd like to ask for you guidance in the following matter in django:

I am using the following models:

class QItem(models.Model):
isWhat = models.CharField(max_length=100, blank=True,
choices=ISWHAT)
slug = models.SlugField(blank=True)
script = models.CharField(max_length=100)
comment = models.TextField(blank=True, null=True)
author = models.ForeignKey(User)

class QuestionSet(QItem):
items = models.ManyToManyField(QItem, blank=True,
through='Ordering',related_name="contained")


class Question(QItem):
answerObject = models.OneToOneField("AnswerObject",
blank=True, null=True)


and their respective, most basic ModelForms:

class QuestionForm(ModelForm):
class Meta:
model = Question

class QuestionSetForm(ModelForm):
class Meta:
   model = QuestionSet


In a view, calling

   qset=QuestionFormSet()
   print q
works just fine.


However,

   q = QuestionForm()
   print q
throws


Exception Type: AttributeError
Exception Value:'NoneType' object has no attribute 'label'

in Django's server. When trying it in the console, I don't get any
errors.


Any ideas why this is the case? Why do similar models behave so
differently, and how could I get rid of the error?
