The 'attrs' argument to the Widget class used with each particular
Field (the Widget is what actually renders the HTML) accepts a
dictionary which will become HTML attribute names and values. For
example:

username = forms.CharField(widget=forms.TextInput(attrs={'class': 'myclass'}))

will become:

Class Attribute in New Forms Input Elements

[Cristian]

Hi,

I've been using the old forms for a while but I'm starting to move
over to the new forms module. One difference that's annoying me is the
lack of the class attribute in the input tags. I use the class tags in
my CSS to change colors and widths. Is there a way to add those back
in (without having to dig into the django code)?

Thanks,
 Cristian

Re: weird "can't adapt" error

[Michael]

Thanks Thomas... your shot in the dark hit it's mark for me :)

I was suffering the same "can't adapt" psycopg2 error (worked fine
with sqlite), but it was due to the exact reason you stated.

Although your solution is probably better in the long run, another
solution is to simply convert the result of slugify into a normal
string (as slugify now returns a django.utils.safestring.SafeUnicode
object and the psycopg2 cursor cannot convert this to a string). For
example:

>>> from django.template import defaultfilters

>>> self.group_slug = defaultfilters.slugify(self.name)

becomes:
>>> self.group_slug = str(defaultfilters.slugify(self.name))

Thanks again! It's been causing me headaches...

Re: weird "can't adapt" error

[[EMAIL PROTECTED]]

This is just a shot in the dark, but I just solved a similar problem
that just popped up for me.

I noticed that you are creating slugs for your object near where the
error happens.  I had the exact same error happen when creating
slugified names.  It turned out that I was calling the built-in
slugify() filter in django.template.defaultfilters. This code changed
significantly as a part of the autoescaping code that was checked in
starting with r6671.  I didn't investigate all the way to finding out
what part of the filter code was causing the issue, I just solved it
by taking the regex logic out of the filter and putting it in my own
slugify() method.

I was running off the trunk (r6708) with psycopg2.

Hope this helps,
-Thomas

Python Question - How to show the last few elements in a list

[Greg]

Hello,
I have a session variable.  Whenever anybody adds a product to this
session variable it gets stored like so:

request.session['prod'].append(b)

This can make my session variable look like this:

[, , , ]

//

I want to show the last 7 elements in my list,  Occassionally my list
will only contain less than 7 elements...like above.  So in this case
only 4 elements will be shown.  However, I'm getting errors with how I
currently have it setup:

request.session['prod'][len(request.session['prod']) -
6:len(request.session['prod'])]

It doesn't work correctly when I have less than 7 elements in the
list.  I guess it's because I have

'len(request.session['prod']) - 6'

///

Does anybody know how I can show the last 7 elements in my list, and
if my list has less than 7 elements then it shows all of the elements?

case errors in transition to OSX

[[EMAIL PROTECTED]]

Hi,

I just transitions development machines from Ubuntu to OS X.

I noted that urls weren't processing correctly.

For example, domain.com/createAccount would show an error in the
debugging output because createaccount matched none of the patterns in
urls.py. Somewhere along the lines, the url was moved to lower case.

I'm using lighttpd. Perhaps something with mod_rewrite? Nothing I can
see.

I've temporarily solve the problem by wrapping each of the patterns in
this function:
import re
def noCase(s):
# re.I option ignores case
return re.compile(s, re.I)

This seems like a kludge. As another thread in the django group
observed, urls should be specific strings. Incorrect cases should be
auto-forwarded to the correct case.

Thoughts?

Possible causes?

Thanks,
Ivan Kirigin

If there are Python bindings for it, the upcoming filestorage changes
might actually make it very easy to integrate something like this.
I'll take a look around and see what I can find, but my findings won't
really be useful until the filestorage stuff lands in trunk.

For the record, pyClamd[1] does look promising, as it supports
scanning streams as well as files. Even before the filestorage stuff
lands, you might want to check it out.

Perl has a nice library, Geo-StreetAddress, that does some parsing and  
normalization. I looked at porting it to Python, but it has some crazy  
regex code in it. You should be able to call it from Django.

The page below has some other options (like scraping the US Postal  
Service website).

Re: File upload virus scanning

Before it's saved to a file...  that would be tricky.

But this might get you started: http://www.clamav.net/ .  It'll run a

Re: Custom ManyToManyField widget in admin

[Julien]

Thanks again Kamil for your help!

Ok, now I'm trying to put everything together. Sorry I'm just starting
with Django and I am still a bit lost.

What I am not sure about is:
- where to put the view?
- how to hook the view to the model
- how to hook the template with the view.

Could you provide a full example, based on the summarization below?

Thanks a lot!


models.py:
---

class Country(models.Model):
name = models.CharField(max_length=50)
def __unicode__(self):
return self.name

Re: Custom ManyToManyField widget in admin

[kamil]

You would achieve it using "regroup" template tag
First get cities in your view
and create template with code:

var countries = {
{% regroup cities by country as grouped %}
{% for group in grouped %}
"{{ group.grouper.name }}: [
{% for city in group.list %}
'{{city.name}}' ,
{% endfor %}  ]
{% endfor %}
}


(If it dosnt work straigt away just look at  "regroup" template tag in
the docs - idea is there)

add url of this template to js list in model admin code and thats
all :)

question about list_display

[Lucemia]

hello every one:

I have a simple question about list_display feature of Django's admin
site

http://www.djangoproject.com/documentation/model-api/#admin-options

class
Person(models.Model):
first_name =
models.CharField(max_length=50)
color_code =
models.CharField(max_length=6)

class
Admin:
list_display = ('first_name',
'colored_first_name')

def
colored_first_name(self):
return '%s'
%
(self.color_code,
self.first_name)
colored_first_name.allow_tags =
True
colored_first_name.admin_order_field = 'first_name'

It is about how to use color in list_display.
When i use it, I didn't correctly get the colored field of
first_name.
Only get strings like '%s'  in this
field.
Is there anything I misunderstand to make it work correctly?

thanks

There's not really a concept of "source language" with gettext. Instead,
the strings you mark for translation are included verbatim in the PO
file (where they are called msgids). Your translators must be able to
read the msgid stringsto translate it, but that's the only requirement.

Malcolm

Re: How to access method parameters

[keithb]

getattr returns a function, so you want to be sure to call it before
calling split.

var2 = var().split('\\')[1]

Re: How to access method parameters

[Greg]

I tired doing that.  However I guess the end result for var is
different for each way:

var = getattr(self, 'get_%s_filename' % shape)
var = self.get_round_filename()



Because, after I assign var I do the following:

var2 = var.split('\\')[1]



When I use 'var = getattr(self, 'get_%s_filename' % shape)' I then get
the following error:

AttributeError at /admin/plush/photo/add/
'function' object has no attribute 'split'

File upload virus scanning

[leifbyron]

Hi there,

Is anyone aware of a command-line tool that can be used to scan file
uploads for viruses before they are saved to a file? I know this is
not specifically a Django question, but I'm sure a lot of people would
find the answer useful.

Thanks,
Leif

Re: weird "can't adapt" error

[Jarek Zgoda]

OK, filed a ticket, but really I do not have any idea as what might be
"usable information" in this case, just copied what I posted here.
What makes me thinking there's a bug somewhere, is that the code works
for psycopg and sqlite3, but fails for psycopg2.

Is not that I don't want to use:
Image.objects.filter( book__library_owner=request.user)
but I can't use it if I want to create a generic funtion, because
depending of the distance from the model to the model who has the
owner field, it can be:
Image.objects.filter( book__library_owner=request.user) or
Book.objects.filter( library_owner=request.user)
I pass the module to the function:
very roughly:
def list_items_by_owner( module, parent_id ):
for field in module._meta.fields:
 if field.name == 'owner':
 return True
for field in module._meta.fields:
   if field.rel and not field.null:
   parent = field.rel.to
   new_parent_id
   out = list_items_by_owner( parent,  new_parent_id)
   ...

Anyway, what I'm trying to get is quite complicated and the code above
is not correct at all, it was only for trying to explain what I want.
I think I need somethig similar to django.db.query.fill_table_cache
but I'm not sure.

This could be used as a row-level permissions. it has some
inconvenient because depending on the number of ForeignKeys, the
recursive function might take longer.

I'm pretty sure I didn't explain myself clear, I do my best :-)

Thank you.

Re: weird "can't adapt" error

[Jeremy Dunck]

"Can't adapt" is quite a vague error that psycopg2 issues.

Your issue is (apparently) something to do with encoding, and that's
different than Sandro's issue.

Please include more information, especially if you do decide to file a
ticket.  I can't help with the info given so far...

I understand you're running wsgi rather than mod_python, but if you're
running multiple interpreters, you'll still have the problem discussed
there.

Re: weird "can't adapt" error

The problem in my case seems to be strictly related to psycopg2

Should I file a ticket?

There might be. First, you'd have to explain what you didn't like
about doing queries like:

Image.objects.filter( book__library_owner=request.user)

Since you don't want to change your models, only your Library model
maintains the source of ownership and so, by definition, all your
queries would have to lead to a check on the Library.owner field
thereby ending up with filters like xyz__library_owner=some_user.

When you're passing in something to iregex, you're using the database's
syntax for regular expressions. So, yes, it varies across databases.

The question doesn't make sense. 404 and 500 status codes are special
cases in that they are generated in response to certain exceptions. All
other status codes are generated directly by your views by returning an
HttpResponse and setting the status code (or returning one of the
special classes in django/http/__init__.py).

So there's no reason to be generating the other status codes via the
default handlers: you're execution path will never get to the point
where the request/response handler (wsgi.py or modpython.py) is handling
an exception for some other response code.

Malcolm

If you mean that every single time you access the field the choices
might be different, then you don't want to be using 'choices' here. You
want a many-to-many field instead. If you mean that you won't know the
value of choices until the *first* time you access the field, read this:

I think I understand now. I thought the error you mentioned was part
of your own code, so I apologize for my misunderstanding. It looks
like you had a version of IPython designed for Python 2.4, but it was
being run against Python 2.5. It was making an assumption about how
__builtin__.exit worked, which was no longer valid.

You should be able to use IPython again, as long as you make sure to
get a version that's compatible with Python 2.5.

I don't use IPython myself, so I can't verify any of this, but that
seems to be what happened to you.

That's interesting, but I think that leaving the models untouched
would be better.
Do you think there is a different way?

As usual, I'll respond to this as I've been doing a good bit of work
in this area lately. There's no "official" way to do this yet, but
there are ways to get the job done. Take a look at the links below for
more information on some techniques.

I'm doing a good bit of work on making Django handle renaming a bit
better, and I'm hoping it will land during the next sprint on December
1. There's no guarantee of that, of course, but that's my personal
goal. That will be documented thoroughly when it lands, and I'll make
an announcement here on django-users whenever that is, sprint or not.

Re: problem with "python manage.py shell"

[Nader]

I have looked at my system and found that I has installed also
Python-2.4.4 and IPython. I have firstly uninstalled Python-2.4.4 and
tried once more the same command "python manage.py shell'' in project
directory. I have got the same  problem. Then I have uninstalled the
IPython also, and the problem is solved!
If I do "python manage.py shell'' I get :

Python 2.5.1 (r251:54863, Oct 26 2007, 01:35:31)

It is Ok! I don't understand what the problem was.

Thank for the giving some indication!

ImageField file naming

[Chris Hoeppner]

Hi there!

I've seen this in patches and stuff before, but most don't work anymore.
Perhaps some Django-insider could advice me how to make Django rename
uploaded files according to some schema when saving them to disk?

Preserving the original filename is ok for most cases, but sometimes it
just doesn't make sense.

It would be nice to be able to include this in the upload_to parameter.
Something like
'upload/%(model_name)s/%(instance_id)s.%(mimetype_extension)s' perhaps?
Maybe, if the parameter ends with a slash, the handler could know "ok.
this is a directory. let's keep the original filename".

Just brainstorming, anyways. I don't know enough about Django internals
to come up with a patch like this.

~ Chris

Re: problem with "python manage.py shell"

[Marty Alchin]

Well, all that tells me is that you're running Python 2.5, which i
already knew from the nature of your error message.

Allow me to rephrase. The message you saw *is expected* under Python
2.5. The code you listed probably worked before, but it *will not
work* in Python 2.5 or future versions of Python.

So the real issue is this: why are you trying to modify
__builtin__.exit? It's not allowed, so you'll need to find another way
to do whatever it is you're trying to do.

Perhaps some more code could explain what you're trying to do, and how
best to get around it.

I'm not sure what exactly you're trying to do here, but I'll hazard a
guess as to what the "problem" is. Prior to Python 2.5,
__builtin__.exit was a string containing something like "Use Ctrl-Z
plus Return to exit." (on Windows anyway). In Python 2.5,
__built__.exit is a class, which exits the interpreter, when called.
So the following line was invalid under Python 2.4, but became
possible with Python 2.5.

>>> exit()

It looks like you're relying on __builtin__.exit being a string, which
is no longer the case if you recently upgraded to Python 2.5.

Yes, not only is it possible but it happens to be the most common
case: develop on your workstation (Mac, Windows, Linux, doesn't
matter) and then push to a production environment.

> would I face any problems along the way?

That depends on your experience with web application development and
deployment as well as how well your ISP supports Python and all other
dependencies of your application.

Start with the Deployment section under here: 
http://www.djangoproject.com/documentation/

You can always come back here if you experience any specific problems.

Re: Include tag - encoding

[Gabriel Farrell]

I don't know details on this, but there have been a lot of
improvements to the Unicode handling in versions since 0.96, so an
obvious suggestion would be to upgrade to the latest Subversion
trunk.  That will most likely solve your problem.

Re: Complicated question

[RajeshD]

>From what I understand, you want a generic ability to declare an owner
item for any model object.

Django's generic relations work that way. Take a look at the examples
here:

http://www.djangoproject.com/documentation/models/generic_relations/

Specially, instead of TaggedItem in that example, you could have an
ObjectOwner model class. And instead of TaggedItem.tag you would have
TaggedItem.owner_user

Your other objects will not need an owner field anymore. They would be
like the Mineral class in the example linked above.

Hope this gives you a starting point.

Hi Horace,

Depending on your webhost, you will need to use fastcgi or mod-
python.  See http://wiki.dreamhost.com/index.php/Django as an example
-- therein are the steps necessary to get Django running on DreamHost,
a large webhost that supports fastcgi.

Also see http://www.djangoproject.com/documentation/modpython/ and
http://www.djangoproject.com/documentation/fastcgi/.

The tutorial simply covers first steps using the dev server; for
production deployment behind a real web server, visit the

Complicated question

[Grupo Django]

Hello, I'm programing a kind of admin zone for users, where users can
add, manage and delete objects.
I want to do it generic, but I have a big problem now.
Imagine these models:

from django.contrib.auth.models import User
class Library ( models.model ):
library_name = models.CharField(..)
owner = models.ForeignKey( User )

class Book( models.model ):
library = models.ForeignKey( Library )
title = models.CharField(...)

class Image ( models.model ):
front_page = models.ImageField(..)
book = models.ForeignKey( Book )

What I want is a function wich returns the class that have the field
owner, populating the fields tables and where to use it with the extra
method of the object. I have seen fill_table_cache in query.py, but I
don't really understand how it works and if it's suitable for my
needs.
I need it because I want to show only the images that belong to an
user, so I need to make something similar to:
images = Image.objects.filter( book__library_owner = request.user )
I started the recursive function but I almost got crazy and this
morning I deleted everything. As I'd like to do it general, It should
work for diferent models at diferents levels of distance from classes.
i.e.
words = Word.objects.filter( page__book__library__owner =
request.user ) or
libraries =Library.objects.filter( owner = request.user )

Do you have any suggestions?

Thank you very much.

One common Python solution is to snag PyParsing and extend their 
streetAddressParser.py example

http://pyparsing.wikispaces.com/Examples

There are some holes in it (most notably "rd" missing from the 
numberSuffix definition, but the cardinal directions may need 
expansion too from just "N S E W" to include "NW SW NE SW"), but 
it should get you pointed in the right direction and be fairly 
easily extensible.

I've tried with regexps, and it gets *really ugly*.

An alternative might be using the USPS website (or ERSI, Google, 
or Yahoo's website(s)) to do the work for you, but that may not 
scale well and might violate their ToS.

Street address normalisation

[hajo]

I have an issue with users doing a lookup on street address.

the issue is the following:

If the address the user wants is 123A mockingird st. It'll mess up on
street; str. etc...

My solution was to only look at the first "word" in the search box; So
if you have a mockingbird Lane and a mockingbird circle I would return
both. I also ignored street numbers; (This is for a market area
search; not one specific address)

My issues doing this right now are: I'm missing numbered streets
(F.ex: 14th street)

This seems like asuch a common problem; are there any libraries for
this; what is the "correct" way to handle this? How do google;
Mapquest and Yahoo do this? (I don't have quite their resources; but
it would point me in the right direction...)

Thank you very much and everybody have a great thanksgiving.

Hajo

Re: How to define choices that works in admin interface?

[David Marko]

Using this I could create a static list only. But what I mean is
dynamic list based on database query.
I have the following model for keeping the list of different choices .

class Choice(models.Model):
TYPES = (
('os_type','OS Types'),
('os_type','OS Types'),
)

type = models.CharField(verbose_name='Type', maxlength=30,
choices=TYPES, null=False, blank=False)
value = models.CharField(verbose_name='Key', maxlength=30,
null=False, blank=False)
label = models.CharField(verbose_name='Value', maxlength=30,
null=False, blank=False)

@classmethod
def get_choices_for(self, type):
l=[(k.value,k.label) for k in self.objects.filter(type=type)]
l.extend([('','- select -'),])
l.sort()
return (l)

 then on the another model I would like to make specific choices
available:
type = models.CharField(verbose_name='OS', maxlength=30, choices =
Choice.get_choices_for('os_type'), null=False, blank=False)


... but using this technique doesnt work as Django runs
Choice.get_choices_for('os_type')  only one time when application
starts up ... so it doesnt reflect changes made to Choices table.

Include tag - encoding

[cwurld]

Hi,

I have a block of text that I load into a webpage using an {%
include  %} tag. I have two versions of the include file. One in
English, the other in Spanish. I have no problem loading either one.
However the Spanish characters in the Spanish file are not displayed
properly.

I tried putting some of the Spanish text directly in the webpage and
that text was properly displayed. So I am guessing that the include
tag is getting the content from the file as if it were ascii and not
utf-8.

I am using version 0.96.

Any suggestions?

Thanks,
Chuck

How to create groups from code?

[Jose Jiménez]

Hello everybody,

I'm starting a project in django. I need some custom permissions that
i created in the model with "class Meta". Now i need to create
some groups. I've seen that i can create groups from the
administration panel, but... i would like to create from source code,
so, if other person downloads the code and installs django, could make
a "syncdb" and automagically has the same groups.

I've been looking for in google but i haven't found anything. Is it
possible??

Sorry for my english, i hope you understand me.

Thanks.

You need to use django.test.TestCase, not unittest.TestCase. The
latter knows nothing about fixtures. :)

Freenode and django related channels

[ikks]

Hi, some spanish speakers folks are resurrecting a channel on
freenode, it's called #django-es , I would like to know if someone
nicknamed dashinho is on the list.  Or is there a django-freenode
agreement ongoing for the django related channels.

/msg chanserv info #django-es

-ChanServ-  Channel: #django-es
-ChanServ-  Contact: dashinho, last seen: 1 year 47 weeks 3 days
(0h 28m 32s) ago
-ChanServ-   Registered: 1 year 48 weeks 1 day (17h 56m 37s) ago
-ChanServ-Mode Lock: -s+ntc
-ChanServ-  Channel: #django-es
-ChanServ-  Contact: dashinho, last seen: 1 year 47 weeks 3 days
(0h 31m 45s) ago
-ChanServ-   Registered: 1 year 48 weeks 1 day (17h 59m 50s) ago
-ChanServ-Mode Lock: -s+ntc

/msg nickserv info dashinho

-NickServ-Nickname: dashinho
-NickServ-  Registered: 2 years 11 weeks (21h 4m 29s) ago
-NickServ-   Last Seen: 26 weeks (17h 30m 6s) ago
-NickServ-   Last Seen Address: [EMAIL PROTECTED]
-NickServ-  Last Seen Quit Msg: Read error: 113 (No route to host)
-NickServ-Nickname Options: Secure, AllowMemos, MemoNotify,
MemoSignon

Then I went to freenode staff asking for help and I got the following:

 which channel?
 #django-es
 We are starting to meet there
 I would like to contact the op, asking for privileges
 He hasn't been online for 26 weeks currently
 or take control over the channel if s/he doesn't appear.
 There's an ongoing group registration for the django project I
believe.  Hopefully when that's completed we should be able to sort of
the channel for you.
 Ok, thanks, I will ask to django people, thanks

In advance, thanks for your help.

Re: How to define choices that works in admin interface?

[Michael]

The following worked for me:

model field:
type = models.CharField(max_length=10, radio_admin=True,
choices=CHOICE_LIST)

where CHOICE_LIST is a tuple of tuples, defined inside the model if
local, outside if you need it in multiple models,  like:
CHOICE_LIST = (('dbasename1', 'displayname1'), ('dbasename2',
'displayname2'),)

radio_admin=True causes the list to be displayed as a radio select
list (instead of a select/drop list or something.)  The docs at
http://www.djangoproject.com/documentation/model-api/ say the
radio_admin is new in the developmental version.

Hope this helps,
 Michael

Django rocks: Key Ingredient

Hi all, I just wanted to let you all know that we've recently opened
up http://keyingredient.com/ -- we're using django
(+linux,memcached,mysql,sphinx,perlbal,pound...) and things are
running pretty smoothly so far.  The site lets you find, add, and
collect recipes but also goes one step further and allows you to
publish (as in paper) and syndicate (via widgets) your recipes.  I'd
like to thank the Django team and contributors for all their hard
work!

Sounds like you're looking for the getattr() call in the standard 
library...something like

   get_filename = getattr(self,
 'get_%s_filename' % shape)
   var = get_filename()

Well, to be fair, it's doing what it's supposed to be doing, just not
what you want it to do. :) Try something like this instead:

def create(self, wsize, hsize, shape):
func = getattr(self, 'get_%s_filename' % shape)
var = func()

That will look for 'get_round_filename' if you pass in 'round', or
'get_square_filename' if you pass in 'square', etc. Hope it helps.

How to access method parameters

Hello,
I have the following code in one of my classes

self.create(50, 50, "round")

def create(self, wsize, hsize, shape):
var = self.get_shape_filename()
etc

///

I get an error whenever it hits the line 'var =

In the above case I'm sending 'round' to the method.  So it's supposed
to be get_round_filename.

Re: Django / Apache Problem (ignores SetHandler)

[Marcin Mierzejewski]

Hi,

You can use django.views.static.serve.
In my application I have the following link in my urls.py

(r'^css/(?P.*)$', 'django.views.static.serve', {'document_root':
'%s/templates/css' % APPLICATION_ROOT }),
(r'^javascript/(?P.*)$', 'django.views.static.serve',
{'document_root': '%s/templates/javascript' % APPLICATION_ROOT }),
(r'^images/(?P.*)$', 'django.views.static.serve',
{'document_root': '%s/templates/images' % APPLICATION_ROOT}),
(r'^media/(?P.*)$', 'django.views.static.serve',
{'document_root': '%s/media' % APPLICATION_ROOT}),

Where APPLICATION_ROOT is the physician path to my Django application.

And when I want to access to image file, I use the following link: /
images/image_name.jpg.

Marcin

Django / Apache Problem (ignores SetHandler)

[idioglossiahh]

Hi everybody,
There are lots of discussions on the internet concerning this topic - but I
couldn't find any information that helped me. I know that this is not 

necessarily a Django topic but perhaps there are more people here who find
this information helpful.

I am trying to get my Djano project to run on Apache with mod_python.
Everything works fine - but static content like images and css files is not 

displayed/loaded properly.

My directory structure looks like this:
/home/websites/mydomain (root directory of my Django application)
/home/websites/mydomain/static/images (dir for images)
/home/websites/mydomain/static/css (dir for css files)

At the end of my httpd.conf file I have added this:

DocumentRoot "/home/websites/mydomain"


SetHandler python-program
PythonPath "['/home/websites'] + sys.path"
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mydomain.settings
SetEnv PYTHON_EGG_CACHE /tmp/egg-cache
PythonDebug On
AuthType Basic
AuthName "Administration"
AuthUserFile /usr/admin/web/.htusers
Require valid-user



SetHandler None



SetHandler None


But if I call this url in my browser:
http://www.mydomain.com/static/images/image.jpg

I just see standard "Page not found (404)" error page generated by Django.
Which is quite strange because the settings in my httpd.conf say that images 

and static content should NOT be handled by Python/Django.

Any hints for me? I'm using Apache 2.2.0 and mod_python 3.1.3

You could also override the save method of your model and simply
replace all hyphens with underscores there for the slugfield.

Re: using "select_related" .Does it works?

It would. As Samuel points out, select_related's only job is to save
you some database trips. The examples I cooked up above will work fine
with or without select_related(). In this case, select_related won't
save him any DB trips but the image.instrument and image.channel
statements would still lead to the related objects (Django will simply
make additional DB calls to follow those relations.)

You can also get the same DB savings as select_related() by explicitly
joining the instrument and channel tables using the .extra method and
its tables keyword[1]

Re: postgresql problem with django api (iregex)

It tries, but isn't heroic.  The options for total portability would
be either no regex support at all (since SQLite doesn't support it),
or an adapting shim (as it currently does) or maybe even dropping
SQLite as an option.

I think the adaptation approach is a good option.

Not really-- you could build your regex based on the engine:

from django.conf import settings

if settings.DATABASE_ENGINE == 'sqlite':
   re = something
else:
  re = something_else

That may make you cringe, but it only makes explicit what is really
going on when you push to prod w/ modified code anyway.

how fixtures can be load in django tests?

[michel bruavics]

Hi djangos,

I check out the django.test.client and want to load a fixture file
called "myfixture.xml".

I added in my project setting a folder (called fixtures):
FIXTURE_DIRS = ('/workspace/project/fixtures/')

myfixture.xml is inside of the folder fixtures.

now I try to load the fixture in my tests.py:

class TestSurfer(unittest.TestCase):
fixtures = ['myfixture.xml']


But it doesn't load the fixture.
I try other names, other places but nothing works for me. I only can
load a file when it's named "initial_data.xml".

Can somebody tell me what I do wrong?


thanks, regards michel

Normally, one would use a foreign key in this case:

choice = models.ForeignKey(Choice)

Consistency between Django syndication framework & generic views (at least)

[[EMAIL PROTECTED]]

Hello,

After reading and viewing the screencast on syndication framework [1],
I let a comment on the site where the "obj" comes from ?

Michael points me to the right url and the answer in the doc [2]

[1] 
[2]  

My concerns is that even if it's two distinct features of Django,
naming convention should be the same I think and that "object" should
be used instead of "obj". At least for consistence purposes.

I do not know if it applies to other part of Django.

Does it make sense ?

Re: postgresql problem with django api (iregex)

[cesco]

Thanks for the reply.
I'm actually trying to match a word boundary with "\\b" before and
after the string, not a backspace. Still one thing is unclear to me:
isn't the django API supposed to be portable across different database
platforms? Does iregex make an exception because of SQLite lack of reg-
exp support? If that's the case then the code has to be changed when
moving to production (that is, likely to a different database
platform)?

Thanks again
Francesco

How to define choices that works in admin interface?

[David Marko]

How to define choices for filed that works in admin interface? When I
define CharField as below, the list of choices is computed intially
and doesn't refresh when data changes in Choices table.

type = models.CharField(verbose_name='Type', maxlength=30, choices =
Choice.filter(""), null=False, blank=False)

Thanks for any hint.

Re: Custom ManyToManyField widget in admin

[Julien]

Hi,

When I look at the html source code generated for the regular
ManyToManyField's widget, it's an html form, not javascript...
Are you sure there is no other way?

Could you please give a full example?

I've spent quite sometime practicing with the tutorials but I'm a bit
lost on this one.

Thanks a lot!

Re: Custom methods for ManyToManyManager

[Tomi Pieviläinen]

Thanks for food for thoughts. Looking at your code got me thinking and
in the end my problem was really simple. I was using the examples in
the documentation a bit too literarily and tried:

def get_query_set(self):
return super(MaleManager,
self).get_query_set().filter(sex='M')

while I shouldn't use super but just self.get_query_set() which
returns the filtered set.

Error Handeling

[Rufman]

Hey

I know that django has error handlers for errors 404 and 500.
My question: Could I just make my own handler and add it to the
defaults in django.conf.urls.defaults? (for example 403 Forbidden)

Thanks

You can easily generate cities list to the javascript dynamically

what makes my case different from this is that the same code creates
probelm from one browser and not from another in a repeatable way. Both are
firefox but running on linux (no probelma) or windows (can't adapt).

I didn't solve it, but it's a month it doesn't happen again...

Re: Custom ManyToManyField widget in admin

[kamil]

Hi Julien

The simple way is hijack city select box with javascript.
You add
js=['http://here comes path to your script']
to admin options in your model
js can look like this:

var countries = {'england': ['London','Manchester'], 'france':
['Paris'] }

document.forms['your_form'].id_country.onchange = function()
{ listCities(this.value) };

function listCities ( country ) {
document.forms['your_form'].id_city.options.length = 0
var l = countries[ country ].length;
for (var i = 0; l > i; i++) {
document.forms['your_form'].id_city.options[i] = new
Option( countries[ country ][i], countries[ country ][i]);
}
}

I hope it helps :)

Re: using "select_related" .Does it works?

[Samuel Adam]

The purpose of select_related() is to limit the number of connections
to the database server.

An analogy would be that if you have a webpage with 4 CSS file
inclusions ( >> from pm.models import Message
>>> from django.db import connection
>>> message = Message.objects.get(pk=1)
>>> '%s sent a message to %s' % (message.sender.username, message.recipient.user
name)
u'admin sent a message to admin'
>>> len(connection.queries)
3
>>>

With select_related(), only one:
>>> from pm.models import Message
>>> from django.db import connection
>>> message = Message.objects.select_related().get(pk=1)
>>> '%s sent a message to %s' % (message.sender.username, message.recipient.user
name)
u'admin sent a message to admin'
>>> len(connection.queries)
1
>>>



The footnote of the select_related chapter is very important:

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

Note that select_related() does not follow foreign keys that have
null=True.

Usually, using select_related() can vastly improve performance because
your app can avoid many database calls. However, in situations with
deeply nested sets of relationships select_related() can sometimes end
up following "too many" relations, and can generate queries so large
that they end up being slow.

In these situations, you can use the depth argument to
select_related() to control how many "levels" of relations
select_related() will actually follow:

b = Book.objects.select_related(depth=1).get(id=4)
p = b.author # Doesn't hit the database.
c = p.hometown   # Requires a database call.

The depth argument is new in the Django development version.

Re: Custom ManyToManyField widget in admin

[Julien]

Hi Kamil,

Thanks a lot for your suggestion!

I have a few remarks though. The list of cities is dynamic, in the
sense that you may add, remove cities from the database at any time
using the admin interface.
So how can we fetch dynamically the list of available cities to
display them in the select widget?

Also, isn't there a "recommended" way of doing? Hijacking with
javascript seems more like a trick. I may be wrong.

Thanks!  ;)

Re: weird "can't adapt" error

[Jarek Zgoda]

I just started receiving the same problem when I try to save an object
that has non-ASCII values in char field (the values are all properly
decoded to unicode)> This seems related to psycopg2 backend, as I do
not observe such behaviour on my dev server with sqlite3 backend. The
model is similar to:

class Label(models.Model):
title = models.CharField(max_length=200, unique=True)

the code that leads to exception is like:

t = 'żołędzie'.decode('utf-8')
label = Label(title=t)
label.save()

The traceback from ipython:

/home/zgoda/www/zgodowie/blog/models.py in save(self)
 42 if not self.slug:
 43 self.slug = slughifi(self.title)
---> 44 super(Label, self).save()
 45
 46

/home/zgoda/www/.python/lib/python2.4/site-packages/django/db/models/
base.py in save(self, raw)
257 cursor.execute("INSERT INTO %s (%s) VALUES
(%s)" % \
258 (qn(self._meta.db_table),
','.join(field_names),
--> 259 ','.join(placeholders)), db_values)
260 else:
261 # Create a new record with defaults for
everything.

ProgrammingError: can't adapt

The docs say select_related() does not follow foreign keys that have
null=True. In your example it would do nothing.
