You want to use Python's 'timedelta' class to calculate a date 20 days
in the past:

http://docs.python.org/lib/datetime-timedelta.html

And then use the 'gt' field lookup, combined with the calculated "20
days ago" date, to do the query:

http://www.djangoproject.com/documentation/db-api/#gt

So something like this:

import datetime

def newarrivals(request):
cutoff_date = datetime.date.today() - datetime.timedelta(days=20)
s = Style.objects.filter(newstyles__gt=cutoff_date)
...etc...

Re: Newforms Field Limit Question

[machineghost]

You are absolutely right Joseph, it was a bug in my code :-(

I had:
forms.ChoiceField(choices=["Yes", "No"])
instead of:
forms.ChoiceField(choices=[("Yes", 1), ("No", 0)])

Thanks for the help.

How to only show records that are less than 20 days old?

[Greg]

Hello,
I have a model called Style that contains a DateField.  It stores the
date when the record was created.  I want my template to only show
Style records that were created less than 20 days ago.  I think that
this needs to be done within the view, but not sure if there is a
filter that I can use in the template.  Here is my model:

//

models.py

class Style(models.Model):
newstyles = models.DateField(auto_now_add=True)

//

views.py

def newarrivals(request):
s = Style.objects.filter(===Not sure what to do here===)
return render_to_response('newarrivals.htm', {'main': s})

///

Thanks for any help

template loading and generic views

[Leo Shklovskii]

I've got a question about the templates that the generic views load.

I have a app (named 'foo' in this example) that has its templates in a 
templates folder to work with 
django.template.loaders.app_directories.load_template_source.

so:
foo/templates/bar.html
foo/templates/bar_list.html

However, trying to use the generic view 
django.views.generic.list_detail.object_list and by default, it looks 
for a template named 'foo/bar_list.html' by default, but that doesn't 
exist. I can move the templates into:

foo/templates/foo/bar.html
foo/templates/foo/bar_list.html

But it seems a little silly to repeat 'foo' twice, and breaks being able 
to use just the template name 'bar.html' in other parts of django.
Alternatively I can specify the template name to object_list, but its so 
nice to pick convention over configuration :-)

Am I just setting up my project incorrectly? Or is there a better 
suggestion for how to deal with this situation?

Re: Stuck on generic relations

[Doug B]

Anwering my own question... it helps to specify an actual join
condition.

This worked:
extra['last_event_when'] = "SELECT event_loggedevent.when FROM
event_loggedevent,event_eventrelation WHERE
(event_eventrelation.event_id = event_loggedevent.id) AND
(event_eventrelation.content_type_id = %s) AND
(event_eventrelation.object_id = common_idxlead.id) ORDER BY
event_loggedevent.when DESC limit 1" % ct

... off to amazon to look for a decent sql book so I can avoid asking
silly questions in the future.

Johnny,

This example is just trying to demonstrate that you can either
paginate urls by using http://www.example.com/somepage/?page=2, or you
can use something like http://www.example.com/somepage/2/ neither one
is restricted to custom or generic views it is all about how you
configure your urls.py.

Stuck on generic relations

[Doug B]

I have a page that needs to display basic user information plus the
last logged activity date for the user, and I need to be able to sort
by that value. (there are two of these relations,I'm just mentioning
one here)  My SQL-fu is very, very weak and I just can't seem to get
it.

There is a table in the middle that is kind of like a many to many,
but with a generic foreign key on one side, EventRelation.  That has
the content_type and object_id values for user, and a normal
foreignkey into the LoggedEvent model that has the field I need.

class LoggedEvent(models.Model):
 when = models.DateTimeField()
 summary = models.CharField(maxlength=255,null=True)
 

class EventRelation(models.Model):
event = models.ForeignKey('LoggedEvent')
objects=generic_relations.GenericManager()
content_type = models.ForeignKey(ContentType,null=True,blank=True)
object_id = models.PositiveIntegerField(null=True,blank=True)
obj = models.GenericForeignKey()

I've tried using extra, but what I thought might work just grabs the
latest event by any user, not the latest event per user (idxlead
model).  If I could apply that select to each user, that is exactly
what I think I'm looking for:

extra['last_event_when'] = "SELECT event_loggedevent.when FROM
event_loggedevent,event_eventrelation WHERE
((event_eventrelation.object_id = common_idxlead.id) AND
(event_eventrelation.content_type_id = %s)) ORDER BY
event_loggedevent.when DESC limit 1" % ct

ct is the contenttype pk for the idxlead model.

There are quite a few users (25,000), and a lot more events.  I
thought about adding a field on the user model and updating that on
each event, but I was worried about an extra write on almost every
request.  I'd appreciate any suggestions.

(Note, I am the author of the Generic Authorization branch.)

The merging was never completed, and has pretty much been put on hold
until the newforms-admin branch is merged to trunk. newforms-admin
makes it all a lot cleaner and easier. I expect to revisit
generic-auth sometime next year. I'm not sure that it will ever make
it into django though. The newforms-admin branch fills a lot of the
needs that generic-auth was trying to solve. It may end up as a 3rd
party add-on at some point.

Are they both going to be rolled into the trunk sometime? or is it one

Accessing many-to-many relations in save()

[Adam Endicott]

I've got an app where I'd like to set some properties in an object's
save method based on ManyToMany relationships. I now realize that this
doesn't work (at least through the Django admin), because the
AddManipulator saves the object, and then saves the m2m relations
afterwards. Basically this is the same issue as [1].

I'm wondering if Malcolm's reply in that thread is still the case
(that a workaround would mean a custom manipulator), or if anyone else
has other ideas. If a custom manipulator is my best bet, how would I
do that? It seems like I would be trying to replace the automatic
AddManipulator with my own and just do extra stuff in the
manipulator's save() method, but how do I spell that?

Oh, it would probably help to mention that I'm on 0.96. Not sure if
newforms-admin would help here or not, but either way it's not really
relevant to me right now.

pagination documentation unclear

[johnny]

I was going over documentation on pagination and it mentions you can
do it in two ways as follows:

URL... ?page=x
or
(r'^objects/page(?P[0-9]+)/$', 'object_list', dict(info_dict))

My question is, you would use

"URL... ?page=x" for regular views?

"(r'^objects/page(?P[0-9]+)/$', 'object_list', dict(info_dict))"
for generic views?

object_list is the function in django.views.generic.list_detail ?

What is dict(info_dict) do?

what is objects in "(r'^objects/page(?P[0-9]+)/$'", model name?

Re: IProblem with registration Form!

[Prateek Parekh]

Apologies. I forgot to include the relevant views.py code

if len(request.POST.get('team', '')) > 0:
# there must be a team name to bother with this...
t = Team(name=request.POST['team'])
t.save()
for i in range(int(request.POST['tmcount'])):
# make sure there's a first and last name...
if len(request.POST.get('tmfname%s' % i,
'').strip()) == 0 or len(request.POST.get('tmlname%s' % i,
'').strip()) == 0:
continue
mem = TeamMember(
team = t,
first_name = request.POST.get('tmfname
%s' % i, ''),
last_name = request.POST.get('tmlname
%s' % i, ''),
email = request.POST.get('tmemail%s' %
i, ''),
entsoc = request.POST.get('tmesoc%s' %
i, '') == 'on',
grad_date = request.POST.get('tmgrad
%s' % i, '')
)
t.save()
t.teammember_set.add(mem)
t.registration_set.add(reg)

Thanks again.

IProblem with registration Form!

[Prateek Parekh]

Hello Everyone,
I was working on a code created by someone else using the django
framework. It is a registration form posted at:
http://apps.cob.sjsu.edu/svce/svnif/registration/
And, it recently went online. However, i started receiving complaints
from students that it doesn't work.
After some debugging i came to realize that it gives an error message
only if the "Team name" field is entered. Otherwise, it runs fine.
Also, i know, i can change the Debug option in settings.py to avoid
displaying the error log.
Here is the relevant code in the models.py file

class Team(models.Model):
name = models.CharField(maxlength=255)
def __str__(self):
return self.name
class Admin:
pass

class TeamMember(models.Model):
team = models.ForeignKey(Team)
first_name = models.CharField(maxlength=255)
last_name = models.CharField(maxlength=255)
email = models.EmailField()
entsoc = models.BooleanField("Member of Entrepreneurial
Society", default=False)
grad_date = models.IntegerField("Expected graduation date",
blank=True, null=True)
def __str__(self):
return "%s, %s" % (self.last_name, self.first_name)
class Admin:
pass

Any help would be greatly appreciated.

Thanks,
Prateek

Just look for "width:" and backtrack a bit to see if it applies to a label.

A really wonderful way to answer CSS questions like this is to use
Firefox and install Firebug. You can then display any page and use the
Inspect button in Firebug to tell you which CSS value came from which
CSS style line and even change it in the browser to test out what
effect any change would have.

Re: deseb installation in ubuntu

your previous bug was a standard import issue unrelated to deseb. 
however this looks like it may be a real one.  let me look into it.

actually you'll use "author_list" here - list_detail.object_list appends
"_list" to the value set for "template_object_name"

I don't want to discuss for discuss, but I'm not in agreement with you
with this last paragraph. deseb is useful for database evolution (for
example for adding models to modeles file), that I think it's very
frequent request for normal users, not only developers.

For this reason is for that I want to install deseb. For migrate my
database more easyly

For the other hand, how do you know that my error using deseb is path
python error?. After I put "import deseb" in settings.py and run
"python manage sqlevolve analisi" I get the following error:

 python manage.py sqlevolve analisi

If you see, it appears that deseb is starting (BEGIN line). So, the
path seems to be good (at least it detects deseb). Isn't ?
How can I know if it's path problem or another thing?

You'd replace "what goes here" with what you put in
"template_object_name": "author" (only without the quotes). Of course,
it'd be a little more readable if you use the plural "authors", since
you're getting a list of more than one author.

You'll have to derive the delete() method, and add an os.remove/

How to delete an image off the file system?

[Greg]

Hello,
I have a function 'thesignal' that deletes the Photo record from a db
table.  However, after that is done the photo's still appear on the
file system.  How do i delete these photos?  Here is what I have so
far:

///

models.py

class Photo(models.Model):
photo = models.ImageField(upload_to="site_media/thumbnails/")
thumbnail = models.ImageField(upload_to="site_media/thumbnails/",
editable=False)
thumbnail2 = models.ImageField(upload_to="site_media/thumbnails/",
editable=False)

/

sig.py

def thesignal(sender, instance, signal, *args, **kwargs):
from mysite.plush.models import Photo
a = Photo.objects.get(id=instance.image.id)
a.delete()



I assume I need to add some code to my 'thesignal' function

Re: Signals error - I can't do a import

[RajeshD]

Perhaps try the import this way:

//

sig.py

def thesignal(sender, instance, signal, *args, **kwargs):
 from mysite.plush.models import Photo
assert False, "It got here"


//

What a handy example for the patch here:
http://code.djangoproject.com/ticket/5701

:)

N.B. There is some doubt that the included patch will be included in
Django due to provenance issues with the copied functools code.  There
is a current thread on django-dev regarding this.

Django is a framework for *Python programmers*. You do need to have some
understanding of Python in order to be able to diagnose anything but the
most trivial problems. It would be redundant for us to repeat
information that is already in the Python documentation, so if your
expectations are that you will never have to read anything beyond
Django's documentation, then you are going to find things fairly
difficult.

Even if the required knowledge is only how import paths work and how to
configure them, you need to do some background work here. We aren't
going to cover a lot of that information in Django's documentation
because it is so fundamental to the way Python works that it is covered
in the standard docs already.

The concept of a "normal user" is fairly nebulous, since that could mean
somebody developing with Django or just using a Django application (an
installer -- the role you are playing -- would not typically be the
normal target audience for something like this). Unless you are
installing pre-packaged versions of everything (which you aren't), you
at least need to have a sys-admin's understanding of Python (which means
knowing about standard import paths, etc) to get things working.

I'm also a bit concerned about what you expect to happen at the end of
this project. Something like deseb is *only* useful if you are
developing with Django, and only in semi-advanced situations. Which
means writing Python code. It's not really a tool for somebody just
starting out.

Regards,
Malcolm

Switching between databases with same project/model

[[EMAIL PROTECTED]]

We are in the process of moving an existing webapp/database to
django.  One of the features of our existing setup is the ability to
have a command line tool post data from a remote client to a
production version of our database for all to see or post to a test
database for personal/informal consumption.

We're planning on starting with 0.96 django and I'm looking for a
workaround to the one DB per project design.

The command line tool for submitting data to the DB is using the
django model and api.  To match our previous design we would need
multiple databases with the same schema with just different database
names.

Now my question.  Is there an easy way to change the database settings
dynamically?  Ideally I'd like to parse the url and call a view
function with the appropriate database settings.  This would allow us
to host one webapp for both DB's.

I'd also like our command line tool to grab the DB name from the args
and pass it to the django settings for the model.


If there's no easy way to do this the only idea I've had is to host
two versions of the project on the same web server with different DB
settings.  We could then wrap the command line tool with a sed script
to edit the setting.py file on a remote client using the tool before
submitting data to the server.

Any feedback is appreciated.

Cheers,

-Brian

Need help with related objects.

[aabele]

Hallo - i'm kind of newbie in django, but actually like it very much.
I need to make a search panel in web site where users could search
worker by name, city etc, and by working time and day. I would like to
make this panel using django db-api, not raw sql.

Here are two models.
--
class worker(models.Model):
name = models.CharField(max_length=100,blank=True)
city = models.CharField(max_length=100,blank=True)
address = models.CharField(max_length=100,blank=True)
notes = models.TextField(blank=True)

class WorkingDay(models.Model):
day = models.ForeignKey(Notary)
worker = models.ForeignKey(Notary)
wrk_from = models.TimeField(blank=True,null=True)
wrk_to = models.TimeField(blank=True,null=True)
--

I made search function, and while I tried to search by the field of
first model it worked quite well. Now I'm stock with the search by
workingdays.

--
worker_list = worker.objects.filter(**notary).extra(
select = {
'found_wrk_days': 'SELECT COUNT(*) FROM worker_WorkingDay
WHERE worker_WorkingDay.worker_id = worker_worker.id etc blabla ... ',
},

where=['found_wrk_days > %s'],
params=[0,]

)
--
Any help (or just link to rtfm subject :) will be appreciated. Thanx
in advance.

Sounds like a circular import problem.

You might want to try this:

No it's not working. that's why I am making this signal stubs.

Signals error - I can't do a import

[Greg]

Hello,
I have a very strange error.  When a Style gets deleted I want my
signal to get called and the signal function will delete the
appropriate photo.  I created a new file called sig.py which just
contains my 'thesignal' function.  The problem arises when I do 'from
mysite.plush.models import Photo' in my sig file.  I get the error
'ImportError: cannot import name Photo.  I have no idea why it's doing
this?  I wonder if it has something to do with because I'm doing a
'from mysite.plush.sig import thesignals' from within my models.py
file.  I wonder if since both .py files are importing functions from
each other if that is causing the error.  However, in all the
documentation I've read about signals the examples do the same
thing.

Below is my code:



models.py

from django.dispatch import dispatcher
from django.db.models import signals
from mysite.plush.sig import thesignal

class Photo(models.Model):
photo = models.ImageField(upload_to="site_media/thumbnails/")
thumbnail = models.ImageField(upload_to="site_media/thumbnails/",
editable=False)
thumbnail2 = models.ImageField(upload_to="site_media/thumbnails/",
editable=False)

class Style(models.Model):
name = models.CharField(maxlength=200, core=True)
theslug = models.SlugField(prepopulate_from=('name',), blank=True,
editable=False)
image = models.ForeignKey(Photo)

dispatcher.connect(thesignal, signal=signals.post_delete,
sender=Style)

///

sig.py

from mysite.plush.models import Photo

def thesignal(sender, instance, signal, *args, **kwargs):
assert False, "It got here"

//

The problem arises whenever I add the line 'from mysite.plush.models
import Photo' from within my sig.py file.  My command prompt
immediately errors out with 'ImportError: cannot import name Photo'

Sorry James, but I'm not a programmer. I only want to run deseb easyly
as I run django.
The think I like to django is that it's simple: no SQL knowledge is
required, no programming language knowledge required, 

I choose django among others (ruby on rails requires SQL, symphony
have more complicate organization, etc. )for this reason

Perhaps I have to read python doc, but my intention is only follow
deseb/django documentation. If normal user have to read python doc,
then django became not simple, I think

But, thanks for your recommendation

Regards,
Xan.

In theory (following instructions) I have only to touch settings.py
Why now I have to change manage.py?

What change I have to put in DJANGO_SETTINGS_MODULE?

Re: How to allow a ForeignKey field to be null

[Greg]

Jeremy,
I tried and it still doesn't work.  Below are part of my models.py and
views.py files:



models.py

class Delivery(models.Model):
name = models.CharField(maxlength=100)
url = models.CharField(maxlength=100)

class Orders(models.Model):
s_name = models.CharField("Name", maxlength=100, blank=True)
s_address = models.CharField("Shipping Address", maxlength=100,
blank=True)
s_city = models.CharField("Shipping City", maxlength=100,
blank=True)
s_state = models.USStateField("Shipping State", blank=True)
s_zip = models.CharField("Shipping Zip", maxlength=100,
blank=True)
delivery_method = models.ForeignKey(Delivery, null=True,
blank=True)

/

views.py

def success(request):
o = Orders()
o.s_name = request.session['orderdetails']['s_firstname'] + " " +
request.session['orderdetails']['s_lastname']
o.s_address = request.session['orderdetails']['s_address']
o.s_city = request.session['orderdetails']['s_city']
o.s_state = request.session['orderdetails']['s_state']
o.s_zip = request.session['orderdetails']['s_zip']
o.save()

/

Notice how when I'm creating a new order in my view I don't specify a
value for o.delivery_method.

Here is the error that I'm getting when I get to o.save():

IntegrityError at /plush/cart/success/
plush_orders.delivery_method_id may not be NULL

Thanks for any help

I dont want to use that, because it is basically unmantained - what it
does is very nice and if I were sure this works with django 1.0 and
such I would use it. Also I dont want to re-write D-M because it does
a lot of things I dont need.

Hm, I dont want that, because *all* fields are to be translated in
every language. Its just simpler that way. No field sharing between
languages.

about my question: there seems no solution to make a model with
uniqueid=language+id? (I know mysql/postgres can do it)

Re: Better FileField

[Marty Alchin]

As Malcolm mentioned, I put a lot of time into a patch to solve a
great many problems with FileField, even more than the ones you
mentioned. It's not in trunk yet, and I don't know when it will be,
but I'll answer your questions to give you an overview of how things
will likely work. Keep in mind that it does more than this, but since
these are your concerns, I'll address just those.

> * I don't want to store the files in MEDIA_ROOT, since
>the access needs to go through django for authentication.

The new patch allows you to specify any root location you like,
independent of MEDIA_ROOT. You can even specify a root for any or all
of the FileFields in your project.

> * The containing directory should be given by the model of the FileField.
>   Example:
>

>if myfriend has id=1234 the file should be in .../myfriends/1234/

Given that you would be able to specify a different root directory for
each FileField, the model name would be easy to include, it just
wouldn't be automatic. As for including the ID as part of the path,
that's something a few other people have requested, and I'm still
trying to work out if there's a decent way to go about that. As it
stands, the patch doesn't support it.

> * The database should contain the unicode filename.

I'm not a unicode expert, so I won't pretend to know about the
"should" aspect of this, I'll defer to Malcolm on that. The patch
would, as Malcolm mentioned, provide a way for you to override how the
FileField generates the filename for use on the filesystem, as well as
what's stored in the database. So it would be fairly simple to include
this functionality on your own, even if it's not part of the standard
mechanism.

Yes, and more. :)

Mostly.

The new FileField patch provides a different (better, in my opinion)
approach to this, so I expect that ticket would end up getting closed
with a note on how to use the new system to do the same thing. We'll
see.

This sounds more like a bug in *your* code than a bug in Django. There
is no limit that I'm aware of. "too many values to unpack" often
happens when you try to unpack what you think is a tuple but is
actually a sting... ie ('test') instead of ('test',).

No one can really help unless you post a traceback though.

Any halfway capable filesystems can handle non-ASCII characters, so this
is just an arbitrary restriction. It's something that could be
overridable (since people want pretty much arbitrary control over the
filename anyway, it's just another part of that), but it's not a default
requirement.

There's a ticket in track by Marty Alchin to redesign large portions of
the FileField storage and the like. That should solve most of your
issues.

Better FileField

[Thomas Guettler]

Hi,

I like django, but not models.FileField.

* I don't want to store the files in MEDIA_ROOT, since
   the access needs to go through django for authentication.

* The containing directory should be given by the model of the FileField.
  Example: 

class MyFriend(models.Model):
picture=models.NewFileField(...)

   if myfriend has id=1234 the file should be in .../myfriends/1234/

* Unicode filenames should be encoded in pure ascii in the filesystem.
   The encoding should be reversable, so that you can get the unicode
   string back. This could be done with utils.http.urlquote().

* The database should contain the unicode filename.

Has someone the same problems?

Has someone solved/coded this?

  Thomas

PS:
This patch only uses a better filename normalization: 
http://code.djangoproject.com/ticket/3119
The unicode name get's lost.

No, it shouldn't. It should return a string that can be coerced to ASCII
(there's no such things as non-7-bit ASCII, so you can leave the prefix
off), but the type of the object is unicode in order to be consistent
with everything else Django returns.

linking to external resources

[bayo opadeyi]

Hi,
I am new to django and am rewriting a site i did with php.
In the php app, i could link to some external .pdf or .chm files like this
file_name, where the path and filename were
drawn from a mysql database, and the file
will just open. while trying to reproduce this functionality in django,
i've tried putting the files in /site_media/resources' folder and
linking to it from
the template via  which works
well for the .pdf files (they open in the browser), but .chm files try to
open in the browser and just shows me lots of (IMHO) garbage
Help, anyone?

Re: Multilanguage - I know what I want, should I do it this way?

[Horst Gutmann]

Well, IMO you would have some ForeignKey back to a language neutral
model where you can also store those fields you want to share in all
languages. Then you could use the unique_together attribute for the
Meta class of your language-dependent model.

Something like:

class Article(models.Model):
   pubdate = models.DatetimeField()

class ArticleI18n(models.Model):
   article = models.ForeignKey('Article)
   language = ...

   class Meta:
   unique_together=(('article','language'),)

Just an idea :-)

Multilanguage - I know what I want, should I do it this way?

[simono]

Hi,
I'm currently working on a simple CMS that needs to be multilanguage.
I've read through all the posts on the list and came up with this
simple solution. My use scenario is like this:

* translations are per model (not per field)
* language selection is per request (saved in a cookie or so)

I would do it like this:

all models have an additional language field (charset or so). This
field could be added automagically for every model. But lets make it
explicit in the example:

class Foo(models.Model):
title = models.CharField()
content = models.TextField()
language = models.CharField(max_length=5)

Question 1: the combination of language+id is unique for every entry.
Can I use the two as one primary keys in django? I want several
entries with the same id (!) but different languages to make the
following work. I guess this is a problem for django ORM.

Then I would write a custom Manager, that takes care of loading the
correct language-version for a certain entry ID. something like this:

class FooManager(models.Manager):
   def get_query_set(self):
return super(FooManager,
self).get_query_set().filter(language=cookievalue_or_smth)

thanks for any input.
greetings
 simon

Re: Label and input Filed overlap

Re: Format date according to locale

[Michal Konvalinka]

I suppose that django should do this. In documentation are mentioned
some constants, which are present in
django/conf/locale/en/LC_MESSAGES/django.po : DATE_FORMAT,
DATETIME_FORMAT and others.

How can I use it in python and template code?

The label width (in terms of screen layout) is defined by the style
sheet that the admin app uses
(django/contrib/admin/media/css/forms.css) so one way to fix your
problem would be to edit that file or include your own style sheet
after the forms.css which overrode the label element's width.

There isn't anything explicitly in the API to support this, although
it has been discussed many times. Search the archives (including
django-developers) for 'm2m intermediate'.

There is also a workaround solution, described here:
http://www.djangoproject.com/documentation/models/m2m_intermediary/

TransactionManagementError behind mod_python only

[olivier]

Hi group,

my setup : win xp, python 2.5, apache 2.2.4, postgres 8.2, mod_python
3.3.1,  psycopg2 2.0.5

I have some views decorated by @transaction.commit_manually.
I do transaction.commit() or transaction.rollback() before response,
as I should.

Everything is running fine when I run the development server.
Behind mod_python, I get :
TransactionManagementError: Transaction managed block ended with
pending COMMIT/ROLLBACK

Does anyone know what's going on and what could be the source of the
problem ? I know very little about Apache.

Thanks,

Olivier

Label and input Filed overlap

[Nader]

Hallo,

I have used the Admin interface in my model. In presentation of Admin
page some of the labels have been not present completely. I give an
example:

 This the definition of a attribute in a model
transferMechanism = models.CharField(primary_key=True, maxlength=100)

But in presentation page It has been overlapped with the input field:

transferMechanism ( here comes the widget).
I can't display the widget here but the widget has been overlapped on
the last 3 characters of label.

My question is: How can I self adjust the distance between them? It
isn't meant to make the label name shorter.

Would you give me some information please?

With regards,
Nader

Django uses docutils and restructured text for the documentation of

Just out of interest: Does anyone know how the core of the django

Re: Users vs Sites

[MarcoX]

Good morning Chris.
Thank you for the reply.

I'm developing a CMS (Content management system).
I have 4 sites for 1 customer. For this 4 sites the users are the
same, but the inner users (journalist) that write the stories for the
CMS can write only for 1 site. Then I need to only bind a group of
users (journalist group) to write stories for a unique site.

The permissions that now is possible to specify in django admin
doesn't permit to carry out these specific ties.
I hope that my explanation is enough clear, otherwise I try to explain
it better.

Many thanks.

drdukk, sorry for lack of response on mailing list.  The beta version
of the book has been out for quite a while and is not in line w/
django is some respects.

Even so, when reporting errors like this, putting code on dpaste.com
as well as (full) traceback will generally get you a more helpful and
informed response.

Glad IRC worked for you.  :)

Re: How to delete a table?

[TopRamen]

Greg, if you do not mind losing any sample data you may have in your
tables, you could do a 'python manage.py reset . This will
execute the output of 'python manage.py sqlreset  in your
database. Basically, it will delete your tables, and re-run a syncdb,
which will re-build your database's tables based on your model
definition.

Add Column to ManyToMany Generated Table

[TopRamen]

Gentlemen, I'm new to the Django seen and am currently working on my
first application in it. In part of my model, I have a ManyToMany
relationship between the Purchase class and the Product class. The
ManyToMany relationship is called products and is in the Purchase
class. I'd like to add some additional columns/fields to the
automatically generated ManyToMany table. In this case, Django makes a
new table called _purchase_products. I'd like to store some extra
info in this table such as a password for a download for example. Is
this possible in Django? I've combed the Model API and Google and
can't find an answer to this anywhere.

The only alternative I can think of is to manually make my own
ManyToMany table by actually hand coding a 3rd class with two foreign
key fields... one pointing to Purchase, and the other to Product. Is
this what I should do to get around not being able to add additional
columns to the auto-generate ManyToMany table? Thanks in advance!

Re: Users vs Sites

[Chris Hoeppner]

There *can* be other solutions, but most would be cumbersome and ugly,
like adding a "group" column to each table (the simple way), or using a
polymorphic relationship (the cleaner, leaner, and harder way).

You'll find yourself coding an authorization system on top of django's.
And when it's done, there is the thing I'd call "let the admin know
about it".

What kind of system are you pretending to build? Maybe a few more
details could get me on the right track.

Re: Validation of dynamically generated forms

[pinco]

Frank,

your snippet works great. I just removed the int conversion on
bf_data, since I want to have f.is_valid() = false if the user submits
something different than an integer.

Without you I would never be able to solve the problem.

Thanks a lot.

Format date according to locale

[Michal Konvalinka]

Hi,
I couldn't find anything about formatting a date according to locale.

I have four languages in my settings.py, I use language switcher and
everything works fine. I have a date, for example
date_of_birth = models.DateField(null=True, blank=True)
in my model and I don't know how to format it according to selected locale.

Thanks for any hint.
Michal

Re: Integrate xmpppy with django

[Jarek Zgoda]

This is the simplest (and for me - obvious) way of doing such things.
I see 2 possiblities: either write it as a "long-running", traditional
daemon (if you do not have your own XMPP server) or as Jabber/XMPP
server component. The former is simpler, the later gives you more
flexibility and seems more stable (only one point of failure).
You can always ask assistance on PyXMPP mailing list if you have any
questions, I am sure Jacek Konieczny will help you with Jabber/XMPP
issues.

utils.text.urlquote returns unicode?

[Thomas Guettler]

Hi,

I looked at the source of urlquote:

utils/text.py:

def urlquote(url, safe='/'):
"""
A version of Python's urllib.quote() function that can operate on unicode
strings. The url is first UTF-8 encoded before quoting. The returned string
can safely be used as part of an argument to a subsequent iri_to_uri() call
without double-quoting occurring.
"""
return force_unicode(urllib.quote(smart_str(url)))

1. safe gets ignored. I created a patch:
   http://code.djangoproject.com/ticket/5734

2. why force_unicode()?
  urllib.quote should return a 7 bit ascii string.

 Thomas

Sorry, I forgot to say that I search for a solution without using 
formfield_callback.

Re: problem with ChangeManipulator

[Gio]

if I do:

articolo = Articolo.objects.get(codice = c)
print articolo.id

I'm on Django 0.96, btw

Ah, sorry, I missed that.

Did you follow these steps?
http://code.djangoproject.com/wiki/AddWYSIWYGEditor#UsingTinyMCEwithflatpages

If so, you've just got your src attribute for your script tags wrong.

I am trying to have tinyMCE for flatpages... Should I be using a model
for that?
