I found the problem in my machine.It is the version problem.
In django 1.0.2 it was not working. when i upgraded to version 1.1 it

how to identified what changed in an instance due to save of a ModelForm?

[Margie Roginski]

Let's say I have a model and an associated ModelForm and am doing the
typical save of the ModelForm to modify the instance.  I'd like to
generate a report that identifies what fields were changed and what
the old and new values were.  I initially did this by doing a deepcopy
of my instance, then saving the ModelForm, then just comparing the
copy with the saved instance.  This works fine when I have no
ManyToMany fields.  But now that I have a ManyToMany field, I find
that deepcopy doesn't really "deepcopy" the ManyToMany field.
Instead, after I save the ModelForm, the deepcopy of the instance now
points to the new ManyToMany field.  IE, if my Manytomany field is
'publications' and the model form specifies 3 new publications, the
deepcopied version of the instance (created prior to saving the
ModelForm) now has a field 'publications' which contains those 3 new
publications.

It looks like to get this right I would have to subclass
ManyToManyField and provide a __deepcopy__ method.

Is there some easier way of doing this that I'm missing?

Thanks!

Margie

Save yourself a headache and ditch godaddy. They're fantastic for domain
purchasing, but leave you wanting when it comes to hosting. Especially
for something like Django. I might suggest http://webfaction.com/ as a
reasonable alternative. Trust me in that any amount you may have prepaid
for godaddy hosting will be worth nothing when compared to the amount of
frustration you will face trying to get something setup on a host that
isn't accomodating.

[Matias]

Where did you get the files?
if you go to the pyfacebook at google
http://code.google.com/p/pyfacebook/the project is now hosted in
github.
So if you downloaded from google it may be outdated.
The installation is much more simpler than what the tutorial says, so i
recommend to download from http://github.com/sciyoshi/pyfacebook/tree/master

ImageField width_wield

[TheIvIaxx]

Assume i have the following:

class Image(models.Model):
image = models.ImageField(upload_to="path/to",
width_field="width", height_field="height"

do i create new Integer fields there for width and height?  With this
i can do things like:

>>> Image.objects.get(pk=1).image.width

However this is just opening the file with PIL which is slow.  The
documentation suggestions the width/height will be updated upon save,
thus being quick :)

class Image(models.Model):
image = models.ImageField(upload_to="path/to",
width_field="width", height_field="height"
width = models.IntegerField()
height = models.IntegerField()

did not seem to do anything.  Am i missing something?

Thanks

Could be a permissions issue - what user is apache running under?

Also, you might want to try enabling the 'allow service to interact
with desktop' option to see if that works. If it does, you might have
to look at another solution or somehow impersonating another user to
do the printing as there are security risks associated with this
option.

Model Theory 101 - Video Sharing App

[thornomad]

Hi - need some suggestions.

I am trying to put together an app that allows users to submit links
to videos at popular video sharing sites (e.g., youtube, vimeo, etc)
-- the links get submitted, data about the video (title, description,
play count, etc) is collected from the respective site and populates
model fields, and the video entry is queued for review.

Caveats: I would like to keep the original "synced" data in its own
field and the "approved" data (as edited) in separate field.  I
imagine that the data first gets brought into the "edit" field, admin
may make changes and save, but the "originating" data will remain
separate and continue to be updated (synced).

This means I need at least

I am stuck, though, on the most appropriate/logical approach to this
app.  Some approaches I've considered.

[1] My first thought is to create base model "Video" (with the main
fields) and then create child models like YoutubeVideo and VimeoVideo
and BlipVideo ... when the user submits a url, would do a regex on it
in the view, and send it through the appropriate child class.  I could
then grab the base Video model in my views (not having to distinguish
the type of video) and use a "leaf" technique (eg,
http://www.djangosnippets.org/snippets/1031/) to run the child's
"sync" or "update" command.  CONS: seems tacky and not easy to build
on.  The leaf technique isn't working when I override the save()
function in leaf models.

[2] Perhaps create only a single model and then create separate
classes/functions to handle the the syncing of data based on the
URLField data ... so, perhaps when Video.update() is called, it would
run the logic then to see what kind of url it has, and how to update
it.  CONS: I thought maybe I could just create a ForeignKey field to a
non-model group of classes with common functions (update, sync,
etc) ... but I am not sure how, or if, I can do that.

[3] Outsourcing.

Hope this makes sense and folks have some feedback about how they
might approach this.  I would like this to be easily expandable -- for
example, add YouTube and Vimeo support to start, and easily add other
sites without having to "hack" it.

I know this is a huge question, but am interested in your "Design
Approach" thoughts ...

Thanks,
Damon

Re: template tag response None. but why?

[MIL]

Hi again. Sorry to disturb you again, but I ran into another issue
related to this template tag I wrote.

I get the following error:

TemplateSyntaxError at /
Caught an exception while rendering: Truncated incorrect DOUBLE value:
'user'


I am not sure what it means exactly, but I beleive the error is
produced by the template tag somehow.

Here is my template tag as it looks now:

@register.tag
def total_num_objects(parser, token):
# {% total_num_objects in viblevraske.User as num_users %}
bits = token.contents.split()
if len(bits) != 5:
raise TemplateSyntaxError, "total_num_objects tag takes exactly 
5
arguments"
if bits[1] != 'in':
raise TemplateSyntaxError, "second argument to 
total_num_objects tag
must be 'in'"
if bits[3] != 'as':
raise TemplateSyntaxError, "fourth argument to 
total_num_objects tag
must be 'as'"
return CountObjectsNode(bits[2], bits[4])


class BlogNode(Node):
def __init__(self, user, varname):
self.user, self.varname = user, varname

def render(self, context):
try:
context[self.varname] = 
Blog.objects.get(user=self.user) # I
beleive this line is causing the trouble
except ObjectDoesNotExist:
return ""



I dont know if its possible to help me with this little information,
but it would be nice :o)

Thanks :o)

Configure Django project in a subdirectory using mod_python. Apps and Admin not found.

[David]

HI guys. I was trying to configure my django project in a subdirectory
of the root, but didn't get things working.(Locally it works perfect).
I followed the django official django documentarion to deploy a
project with mod_python. The real problem is that I am getting "Page
not found" errors, whenever I try to go to the admin or any view of my
apps.

Here is my python.conf file located in /etc/httpd/conf.d/ in Fedora 7

LoadModule python_module modules/mod_python.so

SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonOption django.root /mysite
PythonDebug On
PythonPath "['/var/www/vhosts/mysite.com/httpdocs','/var/www/vhosts/
mysite.com/httpdocs/mysite'] + sys.path"

I know /var/www/ is not the best place to put my django project, but I
just want to send a demo of my work in progress to my customer, later
I will change the location.

For example. If I go to www.domain.com/mysite/ I get the index view I
configured in mysite.urls. But I cannot access to my app.urls
(www.domain.com/mysite/app/) and any of the admin.urls.(www.domain.com/
mysite/admin/)

Here is mysite.urls:

urlpatterns = patterns('',

 url(r'^admin/password_reset/$',
'django.contrib.auth.views.password_reset',  name='password_reset'),
(r'^password_reset/done/$',
'django.contrib.auth.views.password_reset_done'),
(r'^reset/(?P[0-9A-Za-z]+)-(?P.+)/$',
'django.contrib.auth.views.password_reset_confirm'),
(r'^reset/done/$',
'django.contrib.auth.views.password_reset_complete'),
(r'^$', 'app.views.index'),
(r'^admin/', include(admin.site.urls)),
(r'^app/', include('mysite.app.urls')),
(r'^photologue/', include('photologue.urls')),
)

I also tried changing admin.site.urls with
''django.contrib.admin.urls' , but it didn't worked. I googled a lot
to solve this problem and read how other developers configure their
django project, but didn't find too much information to deploy django
in a subdirectory. I have the admin enabled in INSTALLED_APPS and the
settings.py is ok.

Please if you have any guide or telling me what I am doing wrong it
will be much appreciated.

Thanks.

Double check your url patterns.  The {% url %} tag causes your entire url
configuration to get processed, and any errors will get reported as being
due to the {% url %} tag, even though that specific tag is blameless.  The
problem is likely in something you recently added/changed in your url
configuration.

Executing a queryset with MySQL's SSCursor cursor class

[Sam Tregar]

Hello all.  I'm wondering how I can tell Django to use
MySQLdb.cursors.SSCursor instead of the default MySQLdb.cursors.Cursor.  The
critical difference here is that SSCursor uses mysql_use_result and streams
data from the server rather than loading it all into memory at once.
Anybody know if that's possible?  My searches of the docs and code haven't
turned up much yet.

Thanks,
-sam

makemessages clutters project locale files with strings from already translated apps

[Alex Rades]

Hi,
I have many applications in my project. I've carefully translated them
launching manage.py makemessages from within each application
directory, so that each app has its own locale/ directory with
translations.

When it comes to translating project-level strings, and I launch
makemessages from the project top directory, the project .po files are
cluttered with translation strings coming from apps which are already
translated and have their own locale directory.

Is there a way to avoid this?

Thanks

Hi Dirso,

I've done something similar to what you are describing, using jQuery, 
the dynatree jQuery plugin, and some reasonable Django code.  The code 
is available at http://bitbucket.org/tpherndon/django-fedora/, and 
you'll specifically be interested in the djadora/views/browse.py and the 
djadora/templates/fedora/browse_dynatree.html and image_fragment.html files.

I implemented the code as part of a special-purpose web app for 
interfacing with a Java repository system, and the code is far from 
clean and pretty, but it should give you a decent example of something 
that is currently in production.

The way I approached it was to write a couple of views that are designed 
to handle the jQuery dynatree Ajax requests.  Dynatree does the work on 
building the tree in HTML, my views provide the data, and the models 
each have a "parent" attribute that allows the views to figure out how 
to select children for each tree level.

In retrospect, I'd do my best to reuse django-mptt, django-treebeard, or 
similar.  They aren't a direct fit for my use case, since I have 
different models that can contain each other, and from what I've seen 
they are geared to handle only a single model class pointing to itself, 
but I would follow their approach and steal code like crazy.  :)  Or, if 
I had just one kind of model, I'd just add enough Ajax views to power 
dynatree.

Hi, I want display in change_list view, user who added an object and date. I

return self.user.username

def date(self):
return self.date

-- admin.py ---
class OneAdmin(admin.ModelAdmin):

Hi again. I tried that. But it doesnt change anything.

Here is what I tried:

class BlogNode(Node):
def __init__(self, user, varname):
self.user, self.varname = user, varname

def render(self, context):
try:
context[self.varname] = Blog.objects.get(user=self.user)

return ""

and I tried this as well:

def render(self, context):
try:
context[self.varname] = Blog.objects.get(user=self.user)
except ObjectDoesNotExist:
context[self.varname] = None
return ""

admin javascript not working

[Joseph Brown]

I'm having trouble getting the admin javascript to function in production
(debian/apache2).  I've tried creating a sybolic link in the django root
folder, and using a location Alias in apache, but the result is the same.
Admin css files load, images load, and you can view the js files, but they
do not function.

In particular, the calendar date and time images do not render on date/time
fields and my prepopulate fields don't render (this all works in
development)

settings.py:
ADMIN_MEDIA_PREFIX = '/media/'

apache2 default:
# tried this with and with out a symbolic link in the django site's root
#Alias /media
/usr/share/python-support/python-django/django/contrib/admin/media

SetHandler None


You can also *view* all the applicable js files .. they just don't do
anything:

wrong

any RDBM worth its salt can go to tens or hundreds of millions before
you feel it.  granted, of course, that you use appropriate indexes.

Django will automatically add the most important indexes for you.

You can:

2) use sqlalchemy-migrate for database migration and initial data

Different DB tables for models based on object relations.

[zayatzz]

Hello

I'm just as big django newbie as im mysql (or any other sql, for that
matter) newbie. Correct me, if im wrong, but as i understand that the
more rows there is in a table, the slower aquiring stuff from it will
be, right? Since i have an idea, that (if its successful) will
eventually hold hundreds of thousands if not millions of rows of
similar information in one table. For that reason i think its better
to separate this info somehow and as i understand, it is possible to
create new database tables that hold only information related to
certain object - for example to hold only comments to one specific
article in one database table, comments of another article in another
and etc...

Can anyone give me an example of how to do it with django or at lest
point me towards where to find that kind of example. The problem is,
that as im not native english speaker nor very good with sql, i just
dont know what i should google for to find that kind of information.

Thanks!
Alan

Google Group Listserv integration to Django Admin

[Carl Feldhaus]

Hey Guys, you think there is a way to integrate a ListServ from Google
Group into the admin of django?

I have a neighborhood website and we are working on the member
directory, paypal integration for dues but the only thing outside of
the admin is this Listserv and it would be amazing to get it
integrated so its all in one so I dont have to work on keeping two
section (website/listserv) up todate.

Thoughts or suggestions?

I rely on scoping for my templated menus -  I do the following in child
templates to mark a menu item current -

In projects_base.html.djt, say:

{% extends "base.html.djt" %}

{% block menubar0_projects %}
{% with 1 as current %}
{{ block.super }}
{% endwith %}
{% endblock %}

So,it's effectively like the content of the menubar0_projects block in
base.html.djt getting a variable "current" defined. This allows me to
keep all my menu definitions in one template, rather than just
overriding the block wholesale.

I'm a django newbie, maybe there was some other way to do it,
but it works fine.

Re: print PDF on windows

[mettwoch]

I'm now using Foxit Reader. Thanks for the tip. The following works
perfectly in the Django shell and prints the document in
attachment.file.path to the specified network printer:

p = Popen (['C:\\Program Files\\Foxit Software\\Foxit Reader\\Foxit
Reader.exe',
'/t',
attachment.file.path,
'SM03\\HPCOMPTOIR0'])

The same code works silently in a Apache / mod_wsgi context but does
not produce any result on the printer. Do You have any ideas?

You might want to look at django.contrib.databrowse - it sounds like
it does what you want. See:

Re: Path issue with tinymce and MEDIA_ROOT

Hi Wendy, sorry for the delay.

When you use the HTMLField model field you don't need any reference to
TinyMCE in your forms or views, apart from rendering the form media.
For example:

... {{ form.media }} ... 

The admin interface already does this automatically. Django should now
add the Javascript imports for TinyMCE.

It seems you have also added a reference to the django-tinymce view?
Anyway it is trying to load TinyMCE from three places. Ironically, all
three URLs point to the wrong location: error 404 means 'not found'.

I'm not sure how you have set-up serving static files. Maybe you have
forgotten to add something like this to your urls.py:

# Serve static files on development server
if settings.DEBUG:
urlpatterns += patterns('',
(r'^static/(?P.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT}),
)

That would make sense.

Right, that's correct. That view only configures TinyMCE to convert
all textarea elements.

You can try these URL in your browser:
/Users/wendy/mycode/static_media/js/tiny_mce/textareas.js
/static_media/js/tiny_mce/tiny_mce.js

Good luck!

django models/ sqlalchemy

[ajay]

HI,
I have used sqlalchemy for database model creation instead django
default ORM.
Now i need to use fixture to load the initial data as i run test
cases.
This is error message "DeserializationError: Invalid model
identifier:"
The models are not defined in models.py file as i am using
alchemy .
Is there any way i can use fixture to load initial data in my
database .

my structure of app look like this
 models.py
 views.py
  alchemy.py - database models are defined here .
  tests.py


   I am using json as serialized data.

With Thanks
Vijay

Re: Raw HTTP request processing?

[John]

Thanks but it seems that in this example (if I have understood
correctly) it loads the entire request into memory. I need to convert
stuff on the fly using streams on both input and output as both may be
huge. I have a number of stages of transformation and it wouldn't take
very many requests to bring the machine to a grinding halt if
everything is being done in memory at each stage.

I have decided to do it in java with jetty, servlets and embedding
jython (which bizarrely for large datasets seems to be more efficient,
standard c python perfomance plunges after certain in memory data
sizes - I believe its the GC strategy not scaling well from what I
have heard).

Forms for views

[gentlestone]

I'm looking for a support for viewing models in templates.

Forms is a nice support but it is made for editing objects, not for
viewing objects. I found some attemps on the internet, like using
forms with ReadOnlyWidgets, but I thing it is not the way.

Forms are great, because a template-designer can use the general
as_table() and don't have to know too much about the model. And also
the dependency between the model and templates are isolated via Forms.
And also it is good when a template-designer can iterate through form
fields or directly use fileds like form.theField attribute.

Unfortunately there is no such support for viewing model instances in
templates. Yes of course, there is a possibility use the "dot" like
instance.theAttribute in the template, but this means strong template
dependency on models and also the template designer can't use _meta
informations like verbose names and so. Yes, I can make for my models
some methods like constructTemplateDictionaryForXyView, feed the
dictionary with model attributes and models opts, but what I am
looking for are support classes like Form and ModelForm for
constructing dictionares for HTML rendering from models metamodels.

I am ready to write such support for myself, but it is a long task and
propably i am thinking in wrong way, because nobody has written it yet.

Return custom view depending on user

[Sandra Django]

Hi friends, another doubt...
I have a group, where all users that belongs to this groups only can access
to a form, and I want that when anyone is logged, go directly to that form,
not to Django view by default. How I can do it? Depending on the group,
return that form.
Thanks for any help,

Re: json serialization error on arrays

[John]

When I have arrays of 100,000+ the performance of lists gets
unacceptable in standard c python. That's why arrays exist in python!

After doing research and testing, I have decided to rebuild the
project in java with embedded jython. For some bizarre reason jython
performance increases with large datasets in memory where standard c
python plunges (From what I hear its that the GC strategy doesn't
scale).

I also can't use django at having to read and convert everything in
memory etc is going to be too bad a hit. Shame, as I like django but
it won't do for this project as there are many assumptions that don't
fit my requirements - I would have to hack it to death to get what I
want and that is a waste of time.

Everything is going to have to be stream based (conversions happening
on the fly) and use efficient use of memory internally for arrays etc.
I now will be using jetty, servlets, jython as I can optimise
everything easily for huge data sets. There is a maximum permissible
time lag for each request.

Newbie Django project, suggestions for code improvement?

[Matt Conrad]

I wrote a little concentration game in Django and put it up on Google
App Engine:

http://matt-scratch.appspot.com/

I'm sure there are some awkward places in the code where I could
leverage Django better.  If anyone is curious and would like to
comment or make suggestions, the source code (Django/SQLite version)
is here:

http://matt-scratch.appspot.com/downloads/ccsite-1-01.zip

If you download it, you'll want to visit /init_colors/ first thing
after running syncdb.  The game won't be playable until the colors are
initialized.  You'll also need to customize settings.py.

The part of the project that bugs me the most is the URL routing.  It
seems awkward to have a matching URL for each view.  I bet there is a
tidier way.  There may be other obvious Djangonic improvements I don't
see yet.

Any suggestions appreciated.

Matt

I tried with reopening the command prompt after setting the path via

also I tried with setting the path in the active command prompt, but
it didnt work.
Anyway if i give "sqlite3" in the command prompt, it gives me the

Admin search error (using auto complete FK widget)

[maco]

Jannis Liedel writes about a great widget for FK fields
http://jannisleidel.com/2008/11/autocomplete-form-widget-foreignkey-model-fields/

I manged to get it to work on one site, but not on others.

Widget uses admin search functionality through url:
/admin/app/model/search/?
q=foo_fields=my_field_label=my_app_name=my_model

However, on some sites using same code and on the same server (running
django 1.1 and python 2.5) I get error:

invalid literal for int() with base 10: 'search'
Exception Location: /Library/Python/2.5/site-packages/django/db/models/
fields/__init__.py in get_db_prep_value, line 361
Python Executable: /System/Library/Frameworks/Python.framework/
Versions/2.5/Resources/Python.app/Contents/MacOS/Python
Python Version: 2.5.1

I tried several different aps, models and fields and got same result.
I googled about the error and all could get was that django can't
search on date fields that have None as default value, but that is not
the case for me here.

I'm not sure I understand the source of your confusion.

The Django install instructions indicate that if you want to use the
Django development code, you should have a checkout of the 'trunk'
director i.e.,:

svn co http://code.djangoproject.com/svn/django/trunk/ django-trunk

In this example, django-trunk is a complete checkout of the Django
code, and it is the directory against which you should be generating
your diff.

Add the patch wherever seems appropriate. Look around for a similar
tests, and put your tests alongside those. If there really is nothing
similar, add a new test module.

However, don't get too hung up on exactly where to put the tests. If
the location you pick isn't ideal, it will get moved by the committer
when your patch is added to trunk. As a patch contributor, the most
important step is to write the test in the first place, and to put it
somewhere so that it can be executed to demonstrate the validity of
your patch.

Yours,
Russ Magee %-)

I don't really understand what you are asking.  I don't know who the "one"
is in your last question nor what "all that stuff" is.

Yes, you are expected to generate diffs from the root of trunk, as requested
in the third bullet here:

http://docs.djangoproject.com/en/dev/internals/contributing/#patch-style

Anyone regularly contributing or using patches from trac will generally be
using an svn checkout of trunk, or a git (or some other DVCS) clone of the
same, so I don't understand what the problem is you are concerned with here?

A committer when considering the patch will expect to be able to apply it to
the root of the trunk.  If you don't generate diffs from the root, or post
multiple diffs to a ticket that need all be applied, then the committer has
to figure out which all pieces are supposed to go together and where to put
each one.  This is much more likely to result in errors than a single diff
generated from the root of the trunk, thus we request single diffs generated
from the root of the trunk.

Whichever seems like the best match.  Without looking at the ticket or
existing tests too closely, I'd guess the extending the existing
error_messages test would be fine.

Authentication integration with Netegrity SiteMinder?

[Adam Stein]

Using Django v1.1/mod_wgsi v2.5.

I'm forced to use CA's Netegrity SiteMinder to authenticate users.  I
couldn't find anything regardng integration with Django (so that Django
can provide authorization).  I have integrated Django authentication
with an LDAP server, but I need to use SiteMinder instead because of
corporate policy.

Figure I would ask to see if anybody has already done this before I try
to figure this out from scratch.  SiteMinder gives me the login name in
an environment variable which I can then tie into the Django user
system.

That's how to do it.  Note that changing the system path via the GUI does
not affect already-open command prompts so you will need to open a new
command prompt or manually do the path update in the command prompt you are
using also.

Re: annotate() type coercion

[Georg Göttlich]

Hello Karen,

thanx a lot for the information and sorry for being so unspecific.
Sounds like my problem. I'm using python 2.5 and sqlite3 (in my dev
environment). So I'll try to upgrade sqlite.

Cheers,
Georg

Though since you don't mention OS, DB, and Python level it is hard to be
sure.  Windows with Python 2.5 and using sqlite is the only time I recall
this being reported, though.  If that is what you are using then at a
minimum you will want to update the level of sqlite you are using.  If not,
details of exactly what you are running would help.

Problem with running the database shell through cmd lime

[Arul]

Hi all,

I am using the sqlite database for django application. I need to alter
the table and i tried to use "manage.py dbshell" command. It shows me
"Error: You appear not to have the 'sqlite3' program installed or on
your path."

I tried downloading the sqlite3.exe file and used "sqlite3 c:\project
\mydb.sqlite" command.
It opens an sqlite prompt and allows me to alter the table.

But i need to use it with the django using the "manage.pt dbshell"
command.
I tried adding the sqlite.exe path to the windows system path. It
didnt work.

Please let me know how to acheive this.

Thanks,
Arul

Re: Django + Godaddy

[Nanopino]

i've actually have semi success in getting django to work on godaddy.
It displays the "Congratulations on your first Django-powered page."
You will have to be signed up for the linux shared hosting Deluxe or
higher plan in order for fastcgi to be enabled. I can show you how to
get it up and running but the only problem is that once it is up and
running you can't do anything with it because the pysqlite2 and python
bindings for mysql aren't installed making django useless. I'm trying
to see if godaddy tech support will "yum install python-sqlite2" but i
really doubt it. They keep trying to upsell me to a VPS. I've been at
them for 2 weeks now... :-/

annotate() type coercion

[Georg Göttlich]

Hello everybody,

I'm not sure if this is a bug in django or if it works as designed.
That's why I'm asking here first, before filing a bug.

When using annote() on a model, it's date values become unicode
values.

Is this normal behavior and if so, is there a way to prevent this?

Coltrane application not appearing on the admin index page

[Gath]

Guys,

Am going through the practical django book and am trying the weblog
application in Chapter 4, but when i go to test the application on my
cms application (that i created from the same book, from Chapter 2 &
3) "coltrane" application does not appear on the admin index page as
the book suggest.

This is my INSTALLED_APPS in the settings.py in the cms application;

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.admin',
'django.contrib.flatpages',
'cms.search',
'coltrane',
)

My admin.py file in the coltrane application looks like this;

from django.contrib import admin
from coltrane.models import Category

class CategoryAdmin(admin.ModelAdmin):
pass

admin.site.register(Category, CategoryAdmin)

Please note when i run the syncdb, the tables are created properly.

Am using Django 1.1
Python 2.6
Windows Vista.

What am i missing out.

_() function in templates

[nabucosound]

I recently discovered that in templates you can do

{{ _("string")|filter }}

so "string" is translated before being filtered.

This is useful for me until this ticket is being commited:

http://code.djangoproject.com/ticket/5972

Anyone knows where in Django documentation is this _() use documented?
I can't find it...


Thanks!

Adding tests to a patch

[Peter2108]

I'm trying to help fix but #6138. I've done a patch for the code and a
separate test.py module. But someone ('Alex') added a request to
"Please put the tests in the same diff as the patch itself, it is
possible to use svn add locally". I'm at a loss here I'm afraid. The
only way I know to generate a single diff that included a patch to
trunk/django/forms/forms.py  and to the trunk/tests/regressiontests/
forms/forms.py is to set up subversion in the 'trunk' folder. But then
can one apply the patch if one does not have all that stuff?

Also where should one place this test - in  trunk/tests/
regressiontests/forms/forms.py or in  trunk/tests/regressiontests/
forms/error_messages.py or in a separate module even?

I browsed arund the bug list but could not find anything helpful, some
had no tests, some had tests in a separate file, but I could not find
one as a model.  I am getting a bit discouraged at the moment.

Thanks for any help,

Peter

Now go read documentation about the django.root option required when

This can occur because Apache normally runs as a special user and that
user will need permissions to access the files in your home account.
The error can thus indicate it doesn't have that permission.

Re: turn of CASCADE ON DELETE

hmm, I found the answers
1. use a pre_delete signal instead of overwrite the model's and
queryset's delete methods
2. use a specific exception subclass and catch it int the view
Am I correct?

What Django installation instructions tell you to set PythonHandler to
mod_python.publisher? Read the Django documentation for deploying with
mod_python again.

No actually. The 'var/www' is likely totally unnecessary and if they
don't prefix project site everywhere as necessary in urls.py and in
imports, then you would actually want:

  PythonPath "['/home/me/', '/home/me/SshConnector/'] + sys.path"

Your render() method should return something, even if it's a blank
string. The default value returned by a function in Python is None, so
the template is simply showing this (converted into a string, ie
'None').

You can use the template.Variable() class to access the real variable
referenced the name you pass to the tag. See

No, syncdb won't do anything - or rather, it will recreate the models
from scratch with the new names, leaving the old ones still there.

The easiest thing to do would probably be to use the db_table option
in the models' Meta class, setting it to the old table names, then
everything will just work (although it might be a bit confusing if you
ever need to access the database manually).

django.utils.translation.activate(), passing the language code you
want to become the active translation (and its complement,
django.utils.translation.deactivate(), which takes you back to the
default).

in the first place this wrong. It should be:

turn of CASCADE ON DELETE

[gentlestone]

Because of Django CASCADE ON DELETE behavior I want to refuse deletion
of the object with related objects. I overwrote my del method in the
model:

def delete(self):
"Allow only if there are no related objects"
seen_objs = CollectedObjects()
self._collect_sub_objects(seen_objs)
if len(seen_objs.items()) > 1:
raise Exception("This instance has related objects!")
super(MyModel, self).delete()

The manager's delete method does'nt call the object's delete method.
So I have to rewrote the manager's delete method also.

But this is not DRY.

What is the correct solution?
How can I propagate the  Exception("The signature has related
objects!") to HTML? Because ugettext_lazy("The signature has related
objects!") does'nt works.

Internationalization in commands (cron usage)

[Tomáš Drenčák]

Hi,
I'd like to send mass email from custom command which will be called
by cron. Problem is that each email could be in different language.
How can I change actual language so ugettext and template rendering
will return correct localized string?
When I don't change anything, internationalization uses default
langue.

thanks,
  tomas

Hey,

The project is located under:  /home/me/SshConnector/
Here is my configuration:


Options Indexes FollowSymLinks MultiViews

allow from all
AddHandler mod_python .py
PythonHandler mod_python.publisher
SetEnv DJANGO_SETTINGS_MODULE SshConnector.settings
PythonPath "['/home/me/SshConnector/', '/var/www'] + sys.path"

And restarted Apache.

But I'm getting:
The requested URL /html/search/ was not found on this server.
Up typing:

Any ideas what is going wrong?
Thanks.

Change my model names - consequences?

[adelaide_mike]

After adding a model to my Django 1.0.2 app I would like to change the
names of two models.  Will the syncdb take care of this for me?  I
anticipate I will need to change the table names in PostgreSQL.

Any caveats?  Any hints?  TIA
