This is a feature of Django, not of the registration app.

If you take a look at the code in django.contrib.auth you'll find your answer.

Problems with ImageField

[Stupid Dustbin]

Hi,

recently I decide to try out the ImageField but it gives me some
problems.

in my models it is

image = models.ImageField(upload_to='/toy_images/')

in my settings.py here are my media settings

MEDIA_ROOT = '/media/'

MEDIA_URL = MEDIA_URL = 'http://localhost:8000/media/'

ADMIN_MEDIA_PREFIX = '/admin_media/'

The image doesn't get uploaded and I'm unable to figure out what
wrong. :(.

Thanks

I think that's best, if you're happy with the class name as the type
(and normally that would be most natural).

You can't change the underlying data type for the automatically
generated primary key without changing Django's source.

So your choices are either to write a custom field or, more easily,
manually alter the type of the primary key column after the table has
been created (see
http://www.djangoproject.com/documentation/model-api/#providing-initial-sql-data
 ).

django.db.transaction.commit_unless_managed() is probably going to be
necessary, since you're implicitly in a transaction here.

Using non-ASCII characters with Django 0.96 is unfortunately not
completely solid. Sometimes things work, sometimes they don't. It's why
we had to put all the work into making things use unicode internally.
Translations are an area that are particularly vulnerable to problems,
since ASCII strings end up being changed to non-ASCII.

There's a not a lot we can do about this except recommend that you
upgrade to use subversion trunk (which will require a bit of porting of
your code). I realise that might not be the easiest solution, but, as I
said, it wasn't possible to fix all the problems without a major change,
so at some point we had to make that change.

Malcolm

Indeed.

I spent a bit of time on Monday going through the differences between
trunk and the GIS branch, looking at what ideas can be usefully merged
back and how trunk can help out things like the GIS changes. Justin is
to be commended for his reasonably unintrusive design changes. They look
very restricted and unlikely to break anything.

So anybody who's staying away from the GIS branch because of some
perception that it's less stable than trunk and they can do a better job
locally should re-evaluate. Trunk maintainers (well, at least one of
them) are paying attention to what's going on in the various branches
and looking for ways to make things easier in the background. It's solid
now and can only become less and less divergent over time.

Malcolm

Only members are allowed to post on this list. Please have confidence

it simply increases the spam. I dont even mark stuff from this list

Everyday I tag about 1-3 messages using GMail's in-built spam
filtering button. The number has gone down from about 6-10 every day.
I don't think Google groups do filtering on email sent to groups and I
think the spam filters are trained per account (each account gets its
own spam filter training data). My biggest gripe with Google's
in-built spam filter button is that it tags entire "conversations" and
does not seem to allow you to tag individual messages. So if a Groups
subscriber replies to a spam message his email (and email address)
gets included in my spam filter training data.

Re: Dictionnary problem trough session

[Francis Lavoie]

Ok, I found my problem.

Because I was storing a object into the session dictionnary, when I called
method to add, modify or delete object's value, the session didn't get
saved.

Are you looking for blogs which write about Django (and thus which
you'd want to read), or blog software written with Django?

Overriding Default Primary Key Type?

[gordyt]

Howdy Folks!

I've got a new project coming up that will generate gazillions (that's
a technical term for a whole lot) of objects for certain objects in
the model.

Is it possible to get Django to use a really large integer type for
the automatically-generated primary key, like a serial or bigserial in
postgresql?

Many thanks!

Yes, assuming ROLE is defined in your models file you will need to import it
when you want to use it from another file.  But that is not why you got a
404 (page not found).  Given that code, you'd only get a 404 if the
Karateka.objects.get call raises Karateka.DoesNotExist.  So you didn't even
get as far as the roles= line (there's no reason to include that in the
try/except btw).  If you had gotten as far as the roles= line and if you had
not imported ROLE from wherever it is defined, you would have gotten a
NameError "Global name ROLE is not defined".

That's not right. There's a lot o filtering going on.
What we see is the few that slips through. After a bit
of spam filter training, these will be gone as well.
After that, the spam senders will figure out a new way
to slip through the filter(s), the filter(s) will learn
and improve, the spam'ers will figure out a new way, the
filter's..., and so on. I get a few spam's now and then
on other lists as well, including Google Groups lists.
Nevertheless, the latest porno spam's are appalling.

After reviewing a few of them, they all appear to have computer
generated gmail.com addresses, I wouldn't be surprised if email from
within the gmail domain is less scrutinized than email originating
remotely.  Or that email going into google groups is not filtered and
then once it originates from the group servers it's given a pass by some
of the filtering.

I'd be surprised if I haven't gotten more than a hundred spam from this
list alone.

I'm subscribed to a number of Google Groups-based lists, and I've seen
spam make it to every single one of them, so django-users is not
unique in that regard. It is a fairly high-traffic list with a large
number of subscribers, which I imagine makes it a more tempting target
for a spammer, but I've seen identical spam messages make it onto the
lists for other popular frameworks and for popular JavaScript toolkits
which use Google Groups as well.

This is one of the few lists where I get spam in my gmail account at

Sounds like you're hitting bug 4787 
(http://code.djangoproject.com/ticket/4787), where the change in 
queryset on the field doesn't get propagated to the widget. You can work 
around by assigning to the widget's choices directly :
ticketform.fields['server'].widget.choices = 
ticketform.fields['server'].choices
(after changing the field's choices, obviously)

Re: Help With Modeling This

[Joe]

You could also add some functions to the models to add pull the
related data

class TagItem(models.Model):
...

def get_related_artists(self):
   # pull the data
   return data

That function is available in the template and can be called inline so
to speak.

Re: spam

Are the other lists powered by Google Groups?  Are they as active as 
Django's list?

Perhaps you should direct your complaints to Google, as I don't think 
the people on this list (or even the owners of the list) can do much 
about it (aside from moderating every new user/post).

The format of these porn spam's is new,
I do believe the filtering will take care
of it soon enough. Takes a few of these to
train the spam filter(s).

Yes, I can get this to work, but it requires knowing exactly how 
Django is going to construct the queries -- what tables will be 
listed and what aliases used.  That means code you get to work now 
may easily break in the future if Django changes how it builds 
queries.  I would not be at all surprised if code that works today 
for this breaks when queryset-refactor lands on the trunk.  But, if 
you really need to make this work, it can be done.

Note that when an alias is used, you must use "real_table AS alias 
lock_type" in the LOCK TABLES statement.

Here's an annotated transcript of how I got lock tables with a 
non-trivial query to work with my DB.  Where I displayed the sql for 
the query I manually split the lines to highlight the tables involved 
in the query.  (Note my database existed before I ever started using 
Django so the tables and column names are not what you might expect 
for a Django DB.)

--

Entry "DJANGOREINHARDT"

Clues.objects.select_related().filter(EntryID__Entry='DJANGOREINHARDT')

It sounds like you're looking for

which, serendipitously happens to use tagging as an example :)

Help With Modeling This

[[EMAIL PROTECTED]]

I've run into a problem trying to model something in Django and could
use some advice.  In a nutshell, I'm trying to relate a single table
to multiple (other) tables using a single foreign key field and
foreign key type.  I'm aware of the manytomany relationship type of
Django but I don't think this will provide the functionality I'm
looking for.

Based on the model below, I have tables named "Artist", "Album" and
"Song".  What I'm trying to accomplish is making lists of records from
these tables and assigning a tag to them.  This will let me pull a
list by tag name and have access to all of its items.  For example, I
might have a Tag named "Legends Of Jazz" that contains 10 tag items.
Some of the tag items point to an Album and some point to an Artist.
Based on the ForeignID field and ItemType relationship, I can create
this list in the database.  A problem arises when I try to extract the
list in a view or template.  There is no "hard" relationship establish
that I use to get items.  If I pull a list of TagItems, how would I
then get the artist or song?

I realize that some readers might question the purpose of creating a
soft relationship like this.  The reason is that it allows me to
create new entities in the database and then establish a relationship
without code or database changes.  If I decided to start tagging
"Genres" or some other type of entity then I would only need to add a
new ItemType to the database table.

The end goal is to pass a list to my template and format each item
according to its type.  I'm actually going to have a view picking tags
at random in order to present different music to the user as they
navigate the site.  This way the site appears to be more dynamic and I
don't have to keep adding content.  Just create some new Tags.

I would appreciate any advice on how to accomplish this in Django.

Here is my current model:

from django.db import models

Re: gettext is not defined - admin site

[ygneo]

Some advances in my investigation about this error.

The problem seems to be in the characters codification. I don't know
if django or maybe apache are codifying badly the special characteres
in spanish needed for translations. The same error happened when I try
to translate title and branding in templates of the Admin Site. I had
to delete every "trans" from templates y put the text directly,
without possibility of translation. I remenbered that recently and I
decided to do the same in calendar.js and DateTimeShorctus.js, getting
disappear all gettext calls and using directly spanish text for
months, days and Today link.

It's a solution for the application I'm doing, 'cause it doesn't have
to be translated, but I think it's not a good solution, and I'm still
wondering waht is the origin of the problema. Exactly the same app
works fine in the same django version but over Ubuntu 7.04 with python
2.5 instead of SuSE 9.X with python 2.3, where I found the problem.

Any idea about this issue?

(Sorry if my english is not so good)

MyISAM table locking.

[Peter]

Hi All,

I tried writing some code to do table locking on a MySQL MyISAM
database.  I used the code below, which seemed to work in basic
examples, but the code would complain of accessing a non-locked table
whenever I made a more complex query such as
objects.filter(__) saying
that the table __ wasn't
locked with "LOCK TABLES", even though I had locked the table for the
foreign key.  Furthermore, it failed to lock if I tried to reference
the table using the syntax of the form of the complex query.

Has anyone had success running table locks?

The code:  (note: I was getting connection using: from django.db
import connection)


 def lock_tables(connection, args):
 
'''
Performs a table lock with the given connection, args is a
list of tuples
with (, )
**Remember to call unlock_tables at some point after this
call
'''
if not len(args):
raise Exception("Must supply args to lock table!")
cursor = connection.cursor()
try:
tbl_clause = [MySQLdb.escape_string(x[0] + " " + x[1]) for x
in args]
except:
raise Exception("Args was improperly constructed")
cursor.execute("LOCK TABLES %s" % MySQLdb.escape_string(',
'.join(tbl_clause)))

def unlock_tables(connection):
 
'''
Unlocks all table locks for the given
connection
'''
cursor = connection.cursor()
cursor.execute("UNLOCK TABLES")

Re: How to select all the values from my Field attribute 'choices?

[äL]

Hello Karen

I have the same problem as Greg has.

If I try to use your code I got an "page not found" error.
Here is my code:

views.py
### CODE ###
def Karateka_edit(request, karateka_id):

from kav.info.models import Karateka

try:
karateka  = Karateka.objects.get(id = karateka_id)
roles= [y for x,y in ROLE]
except Karateka.DoesNotExist:
raise Http404
return render_to_response('info_karateka_edit.html', {
 'karateka'  : karateka,
 'roles'   : roles,
 'user'  : request.user})
### END CODE ###

Do I need to import ROLE like Karateka or do I have an other error in
my code?
Regards,
äL

This is a popular question that I've found a solution to.  It 
might be kinder in the queryset refactor (Malcolm?), but for the 
time being, this is what I've used:

http://groups.google.com/group/django-users/browse_thread/thread/24de9d4b74935296/

Because of the way the underlying SQL builds the query, you 
basically end up asking for two contradictory conditions of the 
same row:

   WHERE x = 1 AND x = 2

which, as you discovered, returns no rows.

The solution I've found is to use an extra() call to build an 
IN/EXISTS[1] subselect that asks what I want.  Thus, it becomes 
something like

   WHERE EXISTS(
 SELECT 0
 FROM  i
 WHERE  AND
   i. = .id
 ) AND EXISTS(
 SELECT 0
 FROM  i
 WHERE  AND
   i. = .id
 )

-tim

[1] FWIW, I've found EXISTS to be faster in PostgreSQL and IN to 
be faster in SQLServer; haven't profiled MySQL or sqlite.

Hi,

I used something like this, but used the root logger (getLogger()).

If there is a call to logging.log(...) before you add your handler,
python automatically inserts one for you. This means the if-statement
above will be false (and addHandler() would not be called), even on the first 
run.

"and" type query over related objects

[James Cordiner]

Hi,

I need to be able to query an object that has a set of related  
objects - the query is to find which objects contain the same set of  
query objects. For example the main object could be a research paper  
and the related object would be a set of topics that the papers could  
contain.

class Topic(models.Model):
 label = models.CharField(maxlength=255)

class Paper(models.Model):
topic = models.ManyToManyField(Topic)

I have tried a few approaches, I thought I could simply chain a  
series of filters or AND some Q objects:

In [28]: p=Paper.objects.filter(topic=t2).filter(topic=t)

In [29]: p
Out[29]: []


In [39]: Paper.objects.filter(Q(topic=t)|Q(topic=t2))
Out[39]: [, ]

In [40]: Paper.objects.filter(Q(topic=t),Q(topic=t2))
Out[40]: []

But these don't work and I end up with an empty query set, but there  
is  a Paper object with both a t and t2 object.

Thanks,
jms.

Re: syncDB

[Marcin Mierzejewski]

Hi,

>From Django Book:
"syncdb command is a simple sync of your models to your database.
It looks at all of the models in each app in your INSTALLED_APPS
setting".

But you can uses --settings option for manage.py.

./manage.py syncdb --settings=mysettings

where mysettings.py contains only your application in INSTALLED_APPS
---
INSTALLED_APPS = ( 'myproject.myapps' )

newforms ModelChoiceField queryset

[Gonzalo Delgado]

Hello there,
  I'm using Django 0.96 here. I've got a couple of models 
related by a ForeignKey that look more or less like this:

 class Server(models.model):
 name = models.CharField(maxlength=20)
 users = models.ManyToManyField(User)

 class Ticket(models.model):
 desc = models.TextField()
 server = models.ForeignKey(Server)


 Then, I define a form to load tickets:

 from django import newforms as forms

 class NewTicket(forms.Form):
 desc = forms.CharField(widget=forms.Textarea())
 server = forms.ModelChoiceField(queryset=Server.objects.all())

OK then, what I want to do is filter the servers in the form according to the 
current user (request.user). The only way I've been able to do this (so far) in 
a view is this:

serversbyuser = Server.objects.filter(users=request.user)
ticketform = NewTicket()
ticketform.fields['server'] = 
forms.ModelChoiceField(queryset=serverbyuser)

 The question is: why doesn't something like this work:

ticketform.fields['server'].queryset = 
Server.objects.filter(users=request.user)
?
 It doesn't end up on any error, but the rendered form doesn't filter out the 
server choices.. any clue?

 Regards.

syncDB

[AngelCaido]

I don't know if this was asked before, but I can't seem to find an
answer
I want to syncDB for a specific application in my site.
Something like when you do

python manage.py sql MyApplication

and it only generates the SQL for that application.
Can I do something like:

python manage.py syncdb MyApplication

Thanks...

You can use many-to-one relation to split Task for more then one
model.
http://www.djangoproject.com/documentation/models/many_to_one/

Task(models.Model):
Description

DueDate(models.Model):
task = models.ForeignKey(Task)
due_date

Status(models.Model):
task = models.ForeignKey(Task)
status

And now, you can assign permission individually for every model.

Marcin

Before I was using pydev 1.2.5 with eclipse 3.2 with mylar.  Now I
just upgraded to eclipse 3.3 and pydev 1.3.10.  Debugger is working,
now I can click on classes, it just takes me there.

If try to install pydev 1.3.10 from eclipse install manager, then you
will get mylar package error.  Just download,

Authorization Model at the Field Level

[Manakel]

Hello Everybody,

I'm kind of new to Django (less than 1week now).
I have the task to migrate an existing web application to django.

This web application had a Authorization model at the Field level.

If i take  a  TASK model for demonstration.

TASK has a progress status field and a due date field
realisator user can only change the status field
owner can change both the status field and
the
initalize the due date field
project manager can initialize the due date field but also change it.

Is there any best practice to manage this kind of very fine grained
authorisations in Django?

Server error/Template Context processors

[Ryan K]

Hi. When there is a server error (error 500 returns) the template
context processors don't seem to be doing anything (not passed to the
template).

I have this template context processor:

import llcom.settings

def site_context(request):
""" Add URL prefixes from settings file to request context """
site_context = {
'link_prefix': llcom.settings.LINK_PREFIX,
'static_prefix': llcom.settings.STATIC_PREFIX,
'no_flash': request.LANGUAGE_CODE in
llcom.settings.NO_FLASH_LANGUAGES,
}
return site_context

and this in my settings:

TEMPLATE_CONTEXT_PROCESSORS = (
'llcom.custom_cp.site_context',
'django.core.context_processors.auth',
'django.core.context_processors.debug',
'django.core.context_processors.i18n',
'django.core.context_processors.media',
)

'static_prefix' is where my media is. But when a 500 error occurs, the
'static_prefix' (as well as 'link_prefix') settings aren't making it
to the template and style sheets are applied. 404 errors are fine. Any
reason for this?

Thanks,
Ryan

Re: i18n model field not translated

[otonk]

problem solved..

it lies on the django.po

i havent remove the

#, fuzzy

mark.. thats why its not translated

link: 
http://groups.google.com/group/django-users/browse_thread/thread/e8476fa11cefc2b7

Notice that the message in question is marked as "fuzzy". That means
the
translation does not quite match the source string. I cannot read
Chinese well enough to know if the string is at all close, but one
obvious difference is that the source string contains a "%d" format
marker whilst the translation contains a "%s" marker.

By default, fuzzy translations are not included in the output. A
translator has to check each one, verify it is correct (or correct it)
and remove the fuzzy comment. Then the result will be include in the
MO
file.

You may wish to update the file and submit a diff of the changes to
Trac
so that it can be committed.


Thanks for the group..
