It didn't help.

Thanks for inspiration, although smart_unicode() and encode('utf-8')
in save() is not helping much, after changing /usr/lib/python2.5/xml/
sax/expatreader.py, line 207:

--BEFORE --

   try:
# The isFinal parameter is internal to the expat reader.
# If it is set to true, expat will check validity of the
entire
# document. When feeding chunks, they are not normally
final -
# except when invoked from close.
self._parser.Parse(data, isFinal)
except expat.error, e:
exc = SAXParseException(expat.ErrorString(e.code), e,
self)
# FIXME: when to invoke error()?
self._err_handler.fatalError(exc)

-- AFTER --

   try:
# The isFinal parameter is internal to the expat reader.
# If it is set to true, expat will check validity of the
entire
# document. When feeding chunks, they are not normally
final -
# except when invoked from close.

data = data.encode('utf-8') # this makes difference

self._parser.Parse(data, isFinal)
except expat.error, e:
exc = SAXParseException(expat.ErrorString(e.code), e,
self)
# FIXME: when to invoke error()?
self._err_handler.fatalError(exc)

It works. Thank you!

XML serialization and Unicode

[l5x]

Hello,

first of all, congratulations!

I have a problem. When trying to open template I get following error:

self._parser.Parse(data, isFinal)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0142' in
position 154: ordinal not in range(128)

I use latest SVN version (1.1) revision 11367. I have # -*- coding:
utf-8 -*-  line at the beginning of the file, and __unicode__ method
is set on the model, which I serialize and on Log model as well.

My serialization:

[ some model ... ]

def save(self, force_insert=False, force_update=False):
super(Record,self).save(force_insert, force_update)
data_xml = serializers.serialize("xml", Record.objects.filter
(id=self.id))
Log.objects.create(user=user, action="zapis", type="Record",
  object=self.id, data=data_xml)

Deserialization:

[ my model: Log ... ]

def deserialized_object(self):
for obj in serializers.deserialize("xml", self.data):
return obj.object   [1]

[1] There is only one object so I use return on the first try.

My template:

{% ifnotequal log.deserialized_object.value
log.previous.deserialized_object.value %}
something
 {% endifnotequal %}

It doesn't matter how do I put data to database: manually using create
() or via form.save(), and it is in UTF-8. In addition I don't have
any problems with database and unicode in other parts of my project,
only during this deserialization.

I tried to pass data to deserializer after using force_unicode, but
the result is the same.

I would appreciate any help.

Best regards,
Luke

If anybody is interested - it works fine with PostgreSQL (psycopg2)
and SQLite3. No luck with MySQL 5 (MySQLdb).

It occured after I had recompiled mod_python 3.3.1 on Apache2.2.3 with
Python2.5 instead of Python2.4.

I can import MySQLdb using both Python2.5 and Python2.4.

With Python2.4 I could perform 'syncdb' but now it is: Connection
object has no attribute 'get_server_info'.

My distro is Debian Etch 4.0 Stable. Django is the newest SVN.

Does anybody know how to fix it?

Yes, I know about it, but I deleted my new parts of code and it is
still the same result. My Eclipse+PyDev doesn't show any mistakes as
well. If there is no other suggestions - I will just check my code
line by line to check what it may be.

Thank you.

You are right. When I load the page I can see the proper value in the
source - it's working. But when I submit the data I get: "(Hidden
field user) Select a valid choice. That choice is not one of the
available choices."

How can I fix it?

fields = ('user', 'big', 'main', 'description')
==

def gallery(request):
data = request.POST.copy()
try:
a = data['main']
other = Photo.objects.filter(user=request.user)
for o in other:
o.main = False
print "main? ", o.main

I have two issues:

1) When I use photo_form.save() I get: (1048, "Column 'user_id' cannot
be null"), despite the fact that the user is in the POST data:
description:u'my desc'
user:   u'2'
2) I wrote:

pre_data = {'user': request.user.id }
photo_form = PhotoForm(pre_data)

And there is a HiddenInput for User ForeignKey in the PhotoForm

But is there any other way to pass the information about User?

If you put /print "hello"/, the server should print it with given

I think that you should use JS/AJAX to update the page after it is

MultiWidget, value_from_datadict, SplitDateWidget

[l5x]

Hello,

Based on this thread: 
http://groups.google.com/group/django-users/browse_thread/thread/fd450734295e450f/68d466b0d6b24eb7

I have the following code for the SplitDateWidget:

class SplitDateWidget(forms.MultiWidget):
def __init__(self, attrs=None):
widgets = (Select(attrs=attrs, choices=DAY_LIST),
Select(attrs=attrs, choices=MONTH_LIST), Select(attrs=attrs,
choices=YEAR_LIST))
super(SplitDateWidget, self).__init__(widgets, attrs)

def value_from_datadict(self, data, files, name):
return [widget.value_from_datadict(data, files, name + '_
%s' % i) for i, widget in enumerate(self.widgets)]

def decompress(self, value):
if value:
print 'value: ', value
value=unicode(value).split('-')
return [value[2],value[1],value[0]]
return None

And I don't know what do I need to change in value_from_datadict to
get this work after request.POST. As for now I get error: "Ensure this
value has at most 3 characters (it has 22)."

I didn't use delete_file, but if you can't solve this you can write

Anyway I'm also curious how to do that without signals.

Re: Best way to make content in templates

[l5x]

Isn't it just putting variable into template? I don't know if I
understand you correctly but for example:

models.py

Image(models.Model)
name = CharField(...)
location = ImageField(...)

YourModel(models.Model)
image = ForeignKey(Image)
user = ForeignKey(User)

(...)

index.html:



views.py:

(...)
from django.template import RequestContext
def my_request_context():
my_model = MyModel.objects.get(user=request.user)
# you can get the Image : my_model.image
return my_model # or my_model.image

and then use it when you need (rememer to add it to
TEMPLATE_CONTEXT_PROCESSORS in settings, and to call the request
context everytime you need it in views in 'render_to_response')

But I don'f now if it is what you need.

You should focus on http://www.djangoproject.com/documentation/templates_python/
(everything is written there)

Re: just starting out with django along with the tutorial - getting a type error

[l5x]

I don't know if it could help, but anyway you should:

1) add the following line at the beggining of models.py

# -*- coding: utf8 -*-

2) change the order of stuff in models, at first fields: CharField
etc, then classes (Admin, Meta) and methods at the end (__unicode__
etc).
3) add after 'coding', at the beggining:

from django.utils.encoding import smart_unicode

3) on model Ticket:

def __unicode__(self):
return self.ticket_numb

change it to:

def __unicode__(self):
return smart_unicode(self.ticket_numb)

I suppose that's the reason. You are returning Integer (ticket_numb is
integer) in __unicode__ when django expects unicode string.

Hope it will help.

overriding User model list_display and fields in Admin

[l5x]

Hello,

I couldn't find the information how to override the 'list_display' and
'fields' of the Django (SVN) User model in Admin interface.

I need to display User altogether with his two profiles. I know that
there is a get_profile(), but I want to display everything related to
User in the Admin, in one place (the same for adding/changing).  Is
there any way to do that? Can I subclass it somehow in a way that it
will work with further Django releases?

If not, is there a possibility to display on the first profile a link
to another profile and vice versa? How can I do that?

If there is no possibility, I suppose the only solution will be to
join these two profiles and show information from the User model in
custom list_display of that 'super profile'.

Any ideas? If my thinking is incorrect, please feel free to correct me.

Doesn't it depend on server ?

If it is by design - it is ok. I thought that I just can't find
information *how* to do it. Thanks for your time & effort.

Re: Attrs in models

[l5x]

This is a great stuff and I'm really glad that you show me that, but I
still wonder if it is possible to do sth like that in a model ;-)
I mean:

Model looks like that:

class ShortNews(models.Model):
url = models.URLField("URL")
description = models.CharField("Desc", maxlength="200")
author = models.ForeignKey(User, editable=False)
date = models.DateTimeField("Date", auto_now_add=True)
status = models.IntegerField("Status", editable=False, default="0")

and I don't know why it is not possible to do sth like:

class ShortNews(models.Model):
url = models.URLField("URL", attr['class':'required'])
description = models.CharField("Desc", maxlength="200",
attr['class':'highlight'])
 ..etc

It's much faster than doing that at every form_for_* and you don't
have to have it spread all over the code. But the point is, that I
don't know if there is something which can allow to do that :)

Thanks,
l5x

Re: Attrs in models

[l5x]

And what if I need a class only in selected fields ?:)
Can I pass it somehow through a list of the fields ?

Something like that should be nice:

list_of_required = ['name', 'username']
MyForm = form_for_model(MyModel, form=
BaseYourForm(list_of_required))

Hm. I guess that I only have to modify the loop:

for i in self.fields:
self.fields[i].widget.attrs['class'] =
'yourclassname'

But what's the name of field ? i.name ? or what ?

Hm.. I suppose that if you change the name of model it'll be okay.

Attrs in models

[l5x]

Hello,

is there any possibility in django to put a widget into a model
instead of creating the whole forms for each model (using widgets
render)? I only need to add a css class to each field in a model...

Best regards
