On top of the above post, I've come accross an error when trying to
sync my db (with having simplified list_displays not those from
above).  When ever I order my classes in the model file like

Fixture
...
Result
...

I run syncdb and get this:

$ python2.4 manage.py syncdb

Which I understand because i'm referring to an object that has yet to

from the first scenario.  The 2 classes are shown below:

ImageWithThumbsField for multiple thumbnails

2007-03-02 Thread omat * gezgin.com


I came across several approaches for managing thumbnails of images and
then I wrote mine to allow user to specify any number of thumbnail
images to be created.

When initializing the field class, specify the dimensions that you
want to have like:

photo = ImageWithThumbsField(upload_to = 'path', dims = ((60, 60),
(120, 120), (600, 600)))


And this class takes care of creation and deletion of the images:

class ImageWithThumbsField(models.ImageField):
def __init__(self, dims = None, *args, **kwargs):
super(ImageWithThumbsField, self).__init__(*args, **kwargs)
self.dims = dims

def save_file(self, new_data, new_object, original_object, change,
rel, save):
super(ImageWithThumbsField, self).save_file(new_data,
new_object, original_object, change, rel, save)
directory = self.get_directory_name()
im = Image.open('%s%s/%s' % (settings.MEDIA_ROOT,
 directory,
 new_data['image_file']
['filename']))
for dim in self.dims:
# resize image
scale = min(float(dim[0])/im.size[0], float(dim[1])/
im.size[1])
if scale > 1:
newim = im
else:
width = int(im.size[0] * scale)
height = int(im.size[1] * scale)
newim = im.resize((width, height), Image.ANTIALIAS)
newim.save('%s%s/%dx%d_%s' % (settings.MEDIA_ROOT,
  directory,
  dim[0], dim[1],
  new_data['image_file']
['filename']), im.format)

def delete_file(self, instance):
super(ImageWithThumbsField, self).delete_file(instance)
(directory, filename) = os.path.split(instance.image)
for dim in self.dims:
try:
os.unlink('%s%s/%dx%d_%s' % (settings.MEDIA_ROOT,
 directory,
 dim[0], dim[1],
 filename))
except (IOError, OSError):
pass

def get_url(self, dim, filename):
return '%s/%s/%dx%d_%s' % (settings.MEDIA_URL,
   self.get_directory_name(),
   dim[0], dim[1],
   filename)


What I couldn't do is to dynamically add methods to return the url of
a resized image when its dimensions are given. I want the image urls
to be accessible like img.image_60x60_url(), if a thumb with
dimensions 60x60 exists.

So, I added the get_url method that returns the url for that purpose
and tried setattr in the loop in the save_file to add those methods as
follows:

for dim in self.dims:
setattr(self, 'image_%dx%d_url' % (dim[0], dim[1]),
self.get_url(dim, new_data['image_file']['filename']))

and I couldn't access it in the views and templates. Then I tried
contribute_to_class but I couldn't find clear documentation of this
method and after some trial and error, I decided to ask for help.

Thanks for any suggestions...

Re: Using HTML/CSS as templates

I agree somewhat. Speaking as a person transitioning from Tomcat to
Django. Dealing with static files is one of the things about Django
that
does take some getting used to. I have it mostly figured out now but

Being curious to see how the experts handle this issue, I looked at
the
Cheeserater example source code.

Firstly, he uses this code in urls.py:

if settings.DEBUG:
urlpatterns += patterns('',
(r'^m/(?P.*)$', serve, {'document_root' :
Path(__file__).parent.child("media")})
)

No problems here. Makes perfect sense.

But when I took a look at the base template, a bit of ugliness reveals
itself:

http://media.jacobian.org/
cheeserater/reset.css" type="text/css">
http://media.jacobian.org/
cheeserater/cheeserater.css" type="text/css">
...

Note the fixed URL for the link to the CSS. In the author's case, he
seems to be fortunate that
the URLs for the media are the same in both production and development
environments.
In general however, the URLs may have to be modified - although this
ought to be easy since
this is within a template.

connecting to multiple databases

2007-03-02 Thread Ewout ter Haar

I have two legacy databases which I can connect to
django separately without problems. I would like to read data from
one, wrangle the data a bit, and write them to the other.

How would I go about that, given that, as I understand it, I can
import the settings only once. I would seem that in principle it would
not be difficult to make a new database connection in mid-script
(I don't need the admin interface necessarily)

I tried to use the multi-db branch, and it worked very nice. But I had
to switch back to trunk because of a bug I encountered, and there are
other django applications running on the same machine, for which
I cannot risk to use a non-production quality branch.

Also, I gave up on the multi-db branch after reading this from Jacob:
(http://groups.google.com.br/group/django-developers/browse_thread/thread/ae4261bb3aa4ea01/)
"A maintainer/champion: for any big feature to have longevity, someone
needs to commit to maintaining the code for the foreseeable future.
Nothing would be worse than to merge in something big like multi-db
and have it break in three months because nobody understands it. If
the maintenance plan for a big feature involves forcing me or another
committer to do more work, it's just not gonna work out."

I hate having to say "no" to cool features like multi-db, but since
this is a volunteer-run project, we have a limited amount of time
available. "

I read this as saying that that the multi-db will never be incorporated
in trunk, because even if all the bugs would be worked out, even if there
would be documation, etc, etc, there is no commiter that wants to maintain
it. If it will never be in trunk, I don't want to use it.

(Am I being controversial here? I don't want to be. I am not
criticizing anybody,
just making explicit my personal reasoning. I don't know how to better manage
branches or contributions in general, and the django developers are doing a
wonderful job in open-source community management. That said, given the
above quote, I do wonder how any branch not developed by commiters
will ever make it into trunk.)

Django Filebrowser and more than one TinyMCE instance

2007-03-02 Thread Dirk Eschler


Hi,

i'm using the Django filebrowser together with TinyMCE in one of my projects. 
Inserting a adv_link from the file browser into the TinyMCE popup only works 
in the first TinyMCE instance.

In the second instance the link becomes #mce_temp_url#. Oddly enough, the link 
is displayed correctly in the TinyMCE popup, but after hitting update to 
apply the link and close the popup, it is rendered into #mce_temp_url#.

Is there any way around this problem?

Best Regards.

Re: Recursion in templates... again

2007-03-02 Thread Adrián Ribao Martínez


Sorry, I didn't find a perfect solution, but I think that it can be done.
You can use the "unordered list" filter in the template and fill an array in 
the view using recursive methods. Then you pass the array to the filter and 
it's done. You can also create your own filter tag, is not difficult, you can 
find some info in the section "extending the template system"
http://www.djangoproject.com/documentation/templates_python/#extending-the-template-system
and in the several files under the django installation path:
 They're in django/template/defaultfilters.py and 
django/template/defaulttags.py, respectively.

I hope this help you.

Avoiding trailing slash in links in templates

2007-03-02 Thread Sambhav


Hi,

I want to use this http://www.example.com/2007/mar/02/?time=2100
instead of http://www.example.com/2007/mar/02/2100/

But when I use this in the template I get this- 
http://ww.example.com/2007/mar/02/?time=2100/
Note the trailing slash. And I can't use it as a GET parameter.

This time parameter is calculated in the view and passed to the
template to use in the link.

Am I doing this totally wrong?
Any way I can avoid that? Can I do this using some other way?

Any help will be appreciated.

Newbie: Admin / Model help


Hi I'm having a problem with some of my modelling for an app I'm
building.

The 2 models of interest i'm using are

class Fixture(models.Model):
  team = models.ForeignKey(Team, "Team", core=True, help_text="The
Howden team involved in the fixture e.g. Under 8's or Senior 1st
Team.")
  venue = models.CharField("Venue", maxlength=1,
choices=Fixture_Choices, core=True, help_text="Home or Away.")
  date = models.DateField("Date", core=True, help_text="Date of
fixture DD/MM/YY.")
  opponent = models.CharField("Opponent", maxlength=100, core=True,
help_text="Name of Opposition to be played.")
  KO = models.TimeField("Kick Off Time", help_text="Time of Kick Off
in 24 hour clock format, e.g. 10:00, or 14:00")
  competition = models.ForeignKey(Competition, "Competition",
core=True, help_text="Competition fixture is for e.g. East Riding
County League 4.")
  class Admin:
pass
list_display = ('date', 'team', 'opponent', 'venue', 'KO',
'competition')
list_filter = ['date', 'team', 'competition']
search_fields = ['date']



class Result(models.Model):
  result = models.OneToOneField(Fixture, "Fixture from", core=True,
help_text="Select the fixture this is the result from.")
  howdenscore = models.IntegerField("Howden Score", core=True,
help_text="Score obtained by the Howden Team e.g. 3")
  opponentscore = models.IntegerField("Opponent Score", core=True,
help_text="Score obtained by the opposition team e.g. 0")
  class Admin:
pass
list_display = ('result', 'howdenscore', 'opponentscore',)
list_filter = ['result',]
search_fields = ['result']

I was wondering in the admin panel for the result, I have list_display
= ('result', 'howdenscore', 'opponentscore')
Is there anyway I can get that admin page to show some of the details
from the fixture class? e.g.
list_display = ('fixture.date', 'fixture.team', 'fixture.venue',
'fixture.opponent', 'howdenscore', 'opponentscore')


TIA (again)

Re: DateField


Thanks for the quick reply Tim,
I dont think people entering m/d/y instead of d/m/y will be a problem
as Its what I think to be the common form in the UK (although I
realise americans often use m/d/y).

I was referring to my model when using the admin page to add a date so
that it only accepts date in the dd/mm/yy format.  And again only
displays that date format to the user.

I'm not sure this question makes a whole lot of sense without
some clarification...dates should be handled transparently as
date objects all over the place.  They have year/month/day
properties that can be accessed, and timedelta objects can be
added or subtracted from them.  They have no inherent "format"
other than a tuple of values (or as a *nix timestamp or what have
you).

The only time the format of a date should come into question is
on actually presenting it to the user (and when reading it from
the user).  For presenting the date, there's the "date" filter
which allows you to format the date in all sorts of ways:

{{ mydatefield|date:"d-m-Y" }}

Reading back the date, one reason for the -MM-DD format is
that it's internationally unambiguous.  If you get a date in the
format 1-2-2006, should that be interpreted as Feb 1st or as Jan
2nd?  It depends on where you are.  Clearly if one of the first
two fields is > 12, you have a definite answer.  But when both
are 1<=N<=12  you have an ambiguity that's better to ensure that
the person entering data means what the program interprets.  If
you must allow your data-entry folks to use d/m/y you may be able
to employ the time.strptime() function to extract what you want.
 Just be prepared to get folks entering m/d/y instead of d/m/y

if everything fails, you can still return to the hard way and use:

{{ form.field1 }} {% if form.field1.errors %} {{
form.field1.errors|join:"" }}{% endif %}

It works pretty well for me and many others.  Writing a template tag

Jinja is super cool. But I would like to keep the PyLucid package small.

Navigations with django

2007-03-02 Thread Sulo


hi guys,

im sorry if this question is frequently asked but what is the right
way to make a navigation in django ... when a database backend is used
for site content storage...

the first question is ... how to link to the sites ... the first idea
is to but an encoded form of the content title in the url ... but this
is some kind of stupid cause if the title changes the search engines
will no longer find the site ... but this is just a minor question ...

the main thing is ... how to put the navigation as an item into
django ... i tried to put it as a template tag inside ... and wrote a
navigation template tag ... but if one wants a section/category/item
navigation this thing ends up kind of messy ...

so the question is is there any std way to build a navigation or how
do you build navigations ... so that i can learn from you ... im kind
of new to django so please be gentil ;-)

thanks for your attention ;-)

regards

DateField


In my models I use DateField quite a few times, is there any way I can
adjust it so it stores information in the database as dd/mm/yy and
retrieves/handles it in this way too rather then its current -mm-
dd format?

Thanks

Rich text editor

2007-03-02 Thread Alessandro Ronchi


Hi to all.
I'm trying to add a rich text editor to a field of my model, following
the tutorial on
http://code.djangoproject.com/wiki/AddDojoEditor

I have this directory structure:

./
./gallery
./gallery/locale
./gallery/locale/it
./gallery/models.py
./gallery/views.py
./locale
./locale/it
./manage.py
./media
./media/dojo (with all the contents of dojo-0.4.1-kitchen_sink.tar.gz )
./media/dojo/dojo.js
./media/js
./media/js/admin
./media/js/admin/AddRichTextEditing.js
./settings.py
./urls.py

into
i have a class with

description = models.TextField(_("description"),help_text='Rich Text
Editing.', blank=True, null=True)
and
class Admin:
js = ['media/js/admin/AddRichTextEditing.js']
pass


The problem is that it doesn't replace the "Rich Text Editing." with the
 editor.

maybe my mistake is on media settings or directory structure?
Must I have something in urls?

in my settings.py I have:

# Absolute path to the directory that holds media.
# Example: "/home/media/media.lawrence.com/"
MEDIA_ROOT =
 '/home/aronchi/documenti/sviluppo/workspace/Brunori/museobrunori/media/'

# URL that handles the media served from MEDIA_ROOT.
# Example: "http://media.lawrence.com";
MEDIA_URL = 'http://localhost:8000/media'

# URL prefix for admin media -- CSS, JavaScript and images. Make sure to use
 a # trailing slash.
# Examples: "http://foo.com/media/";, "/media/".
ADMIN_MEDIA_PREFIX = '/media/'


Is there some other better editor?

Thanks in advance.

Transfer-Encoding: chunked =? Content-Length

2007-03-02 Thread meledictas


Hi all,

Don't know this is a right place to ask this question :(

I got problem when I used django to serve xml-rpc request. By
definetion, The Content-Length of request must be specified and must
be correct (http://www.xmlrpc.com/spec). But some client, they siad
that Transfer-Encoding: chunked." is a valid alternative to Content-
Length. I think this confict to xml-rpc spec. Some web test tools make
a request this way (jmeter) and the problem is django server doesn't
understand it and raise xml.parsers.expat.ExpatError:no element found:
line 1, column 0 exception

If I use Apache instead of django server, will problem be solved?

Any sugguestion is welcomed

Regards

Re: Filtering a blank date field

2007-03-02 Thread Phil Powell


Well, to answer my own question, it turned out that the Q object was
the key to this.  It allows me to use a more complex OR statement,
rather than the usual AND.  So I've ended up with:

class ActiveManager(models.Manager):
  def get_query_set(self):
objects = super(ActiveManager, self).get_query_set()
objects = objects.filter(Q(active_from__isnull = True) |
Q(active_from__lte = datetime.datetime.today()))
objects = objects.filter(Q(active_to__isnull = True) |
Q(active_to__gte = datetime.datetime.today()))
return objects

Filtering a blank date field

2007-03-02 Thread Phil Powell


I'm writing a custom Manager to only return objects which fall within
dates set for Active From and Active To fields.  It currently looks
like this:

class ActiveManager(models.Manager):
  def get_query_set(self):
objects = super(ActiveManager, self).get_query_set()
objects = objects.exclude(active_from__lt = datetime.datetime.today())
objects = objects.exclude(active_to__gt = datetime.datetime.today())
return objects

Here's the gotchya though: if either of those dates aren't set, I want
the object to still be returned.  i.e. if Active From isn't set, then
it's date should be treated as the beginning of time.

An easy fix would be for me to make these required fields, but I'd
quite like them to be optional.  Is there any way I can do this
without writing a custom query?

Steve,

are you importing the correct forms?

from django import newforms as forms

I forgot to change my import once and i got a similar error until
i fixed the import statement.
