Re: i18n variable string translation

[Aaron Lee]

Another problem I am facing is it seems some pages are not being translated
until I hit certain page, after that everything is fine. I am not exactly
sure what the problem is but if you guys experience this problem, would
appreciate some insights.

i18n variable string translation

[Aaron Lee]

Hi guys,

In http://www.djangobook.com/en/2.0/chapter19, there is a paragraph

Translation works on variables. Again, here’s an identical example:

def my_view(request):
sentence = 'Welcome to my site.'
output = _(sentence)
return HttpResponse(output)

(The caveat with using variables or computed values, as in the previous two
examples, is that Django’s translation-string-detecting utility,
django-admin.py makemessages, won’t be able to find these strings. More on
makemessages later.)
It's a bit confusing, one one hand it says Translation works on variables,
on the other hand, it says makemessages won't be able to find these strings.

Which one is right? The makemessages section didn't mention how to "fix"
this problem neither.

Any ideas?

unable to create en-gb for localisation

[Aaron Lee]

Hi,

I am trying to create a UK version of my site and ran into some problems.
I am manually setting my LANGUAGE_CODE to 'en-gb' and use
django-admin.py makemessages -l en-gb and then run compilemessages

For some reason it's not picking up the localised string, I am pretty sure
my setup is correct because I did the same experiment for uk (Ukraine).

Looking at Django's conf/locale I couldn't find an example of Great Britain
English translation setup. Any idea what may go wrong? Thanks

django memcached errors

[Aaron Lee]

Lately I have been seeing the following errors from memcached
[fa...@1246486554.949771] mcm_get_line():1542: memcache(4) protocol error:

to the memcache server: Bad address: Bad address

I am using the latest Django from trunk, libmemcache-1.4.0.rc2,
cmemcache-0.95. I also searched over Google and it seems like a mystery of
how and why it happens. At then end they fall back to python-memcached even
though it's slower.

Anyone know what the problem is?
I wasn't able to reproduce it so it's hard to track down.

Re: Django DB strange behavior

[Aaron Lee]

Thanks James and Karen,
Yes indeed it was the problem, I updated the my.cnf to have
transaction_isolation set to READ-COMMITTED and it works fine now.
Is there any benefit of this approach of the other (connection autocommit)
i.e. performance-wise ?

Django DB strange behavior

[Aaron Lee]

Today I just stumble upon a very strange bug and I am not sure if that's
Django bug or not.

Here's the context:
I have a model Job which has a status field.

For debugging, I run python manage.py shell and do

jobs = Job.objects.filter(status__in=['A'])

*I am using MySQL 5.0 InnoDb*

Re-running this command will NOT get updated result even if a new job with
status 'A' is inserted to the DB (I explicitly turned off buffer_pool cache
and no query cache)
I then open another terminal and do python manage.py shell and run this
command and I got the newly updated result set.

So in summary:
- calling Job.objects.filter(status__in=['A']) does NOT get the latest
result from the DB, running the SQL statement directly in mysql client does
result the correct result.
- do the same query on another shell (i.e. a new python manage.py shell)
correct gets the updated result, but repeated execute gets back stale data
- checking the connection.queries[-1] shows a new SQL was sent to the DB.
- I even turned on MySQL proxy to intercept the incoming query and verify
that a new query was sent.
- ALTER TABLE jobsdone_job ENGINE=MyISAM does the magic and everything works
correctly i.e. repeated execution yields the latest data from the DB.

So is there some InnoDB specific thing in Django that does some "smart"
caching?

Re: admin sorting in ManyToMany fields

[Aaron Lee]

Just to be clear, the ManyToManyField will have 'a', 'c', 'b' listed under
Person1's admin interface with 'a' and 'c' highlighted.
What I want to achieve is to order the name => 'a', 'b', 'c' with 'a', 'c'
highlighted for Person1 and 'b' highlighted for Person2.

What I want to achieve is when I edit Person1 in the admin interface, I want
to order the Name.name i.e. 'a', 'c'
instead of according to 'a','c''s primary key in Name. So I am a bit
confused why Person2 comes into the picture.
Think about a person can have multiple names e.g. screenname, nickname,
username etc ...

I believe that's a legitimate use of ManyToManyField?

Re: proper way to use S3Storage and Django ImageField

[Aaron Lee]

Yes and yes,
here are my settings in settings.py

# Storage Settings
DEFAULT_FILE_STORAGE = 'libs.storages.S3Storage.S3Storage'
AWS_ACCESS_KEY_ID='xxx'
AWS_SECRET_ACCESS_KEY='xxx'
AWS_STORAGE_BUCKET_NAME='userprofile'
from S3 import CallingFormat
AWS_CALLING_FORMAT=CallingFormat.SUBDOMAIN
AWS_HEADERS = {
'Expires': 'Sat, 10 Jan 2049 00:00:00 GMT',
'Cache-Control': 'max-age=86400',
}
#

and I also verified that I have a bucket called "userprofile" in my Amazon
account.
In the DB I have
mysql> select * from userprofile_avatar;
++-+-+-+---+
| id | image   | user_id | date| valid |
++-+-+-+---+
|  4 | userprofile/cs1.jpg |   2 | 2009-01-19 13:46:12 | 0 |
++-+-+-+---+

But I am still getting the exception saying the backend doesn't support
absolute paths.
In django/db/models/fields/files.py line 52 _get_path
  return self.storage.path(self.name)

and my self.name is userprofile/cs1.jpg

Any suggestions?

Re: proper way to use S3Storage and Django ImageField

[Aaron Lee]

So I guess S3Storage doesn't work with ImageField? Can anyone confirm that?

proper way to use S3Storage and Django ImageField

[Aaron Lee]

Hi all and David,

I followed the http://code.larlet.fr/doc/django-s3-storage.html
installation and created a simple model

class Avatar(models.Model):
"""
Avatar model
"""
image = models.ImageField(upload_to="userprofile")
user = models.ForeignKey(User)

By using the upload_to="userprofile" (which is also the example given on the
django-s3-storage.html)
the path would be something like userprofile/my.jpg
which would trigger the file storage backend exception

File "/usr/local/src/djtrunk.latest/django/core/files/storage.py", line 81,
in path
raise NotImplementedError("This backend doesn't support absolute paths.")
where name is userprofile/my.jpg

What's the recommended way of using S3 with ImageField?

How to populate a form field with a Select widget

[Aaron Lee]

I would like to populate a form field which uses a Select widget with
choices in views.py.
I understand I can pass the initial arg to the form but I couldn't find the
correct value to pass.

The choices is a list of tuple
CHOICES = ( ('P', 'Pending'), ('A', 'Active'), ('D', 'Done'))

Any hints?

admin sorting in ManyToMany fields

[Aaron Lee]

Hi I have a ManyToMany field names in my class and I would like to show the
names in sorted order (according to 'name') in the admin interface when I
edit a Person. Right now it's showing by the pk order of Name. What's the
right way to override this order? Thanks
class Name(models.Model):
  name = models.CharField()

class Person(models.Model):
  code = models.CharField()
  names = models.ManyToManyField(Name)

class PersonAdmin(admin.ModelAdmin):
  list_display = ('code',)
  ordering = ('code',)

admin.site.register(Person, PersonAdmin)

template tags for simple comparison

I found this wiki and seems pretty useful in general, is there any reason
why it's not included in Django by default?

Thanks Justin, I was using MySQL and it looks like I do need Postgres to get
the best gis support.
Do people normally switch their DB backend entirely or do they start a new
project for geo stuff and connect the main site to this as a separate
backend? I can see the pros and cons of each approach. Just want to hear
about people's experience

I followed the example and did:
def test_zipcode():
zipcode_mapping = { 'code' : 'ZCTA5CE00',
'mpoly' : 'MULTIPOLYGON',
}
zipcode_shp = '/usr/local/share/census/fe_2007_us_zcta500.shp'

lm = LayerMapping(Zipcode, zipcode_shp, zipcode_mapping)
lm.save(verbose=True)

and tried a few zipcode in Admin interface. I see several problems and want
to make sure it's a data error rather than installation error:

1. There's no 08544 zipcode after the layer mapping. 08544 should point to
Princeton NJ.
2. I do see 08540 and 08542. 08542 seems correct but 08540 shows North
Pole??
3. I also did a shp2pgsql dump with srid=4269 which seems the closest match
of the prj file as compared to spatial_ref_sys in the pgsql db.
 shp2pgsql -s 4269 fe_2007_us_zcta500 zipcode > zipcode.sql
and 08544 is not there.

If so, it does look like the zipcode is incomplete even though the dataset
is fairly recent and from census. Do you have recommendation on what maybe a
better DataSource?

Let say I want to do something similar to your example of HoustonCrimeMap,
and I use Geopy to perform the geocoding to get back the (lat, lon) for each
crime event location and I also want to show the events within a certain
radius R from a point P. Do you store the lat lon as a Point for each event
and construct a polygon of a circle(P,R) and check if the event point is
contained inside the polygon?

What do you recommend as the best practice?

Thanks

GeoDjango question about US zipcode lookup and spatial query

[Aaron Lee]

Hi all,

I am checking out GeoDjango and going through the installation and
presentation.
I esp. like this one which is very well done
http://geodjango.org/presentations/GeoDjango%20-%20A%20world-class%20Geographic%20Web%20Framework%20(DjangoCon%20-%20Sept.%206,%202008).pdf

I do have a few basic questions
- on slide 37, there's a Zipcode model, how does one populate this model?
Are we using fe_2007_us_zcta500.shp? If so, is there a program which
converts the zipcode shape from the shape file?

- on slide 41, there is an Address model, does GeoDjango provide geocoding
which converts it to (lat, lon) for spatial query? If not, does it mean that
one has to query Google/Yahoo/MSFT WebServices?

Thanks
-Aaron

confused about django-tagging usage

[Aaron Lee]

Hi,

I am a bit confused about the best practices for using the django-tagging.
>From the docs/overview.txt. It seems you can either have the tags
stored inside a model OR you can have them stored on the tagging_tag
table.

E.g.
   class Link(models.Model):
   ...
   def add_tag(self, tagname):
  Tag.objects.add_tag(self, tagname)
   def get_tags(self):
  Tag.objects.get_for_object(self)

vs

   class Link(models.Model):
   ...
   tags = TagField()

Assuming the tags are common and have significant overlap across the
objects, it seems better to store them outside the model?
I guess the advantage of using TagField is you can generate a
ModelForm automatically and be represented by a
tagging.forms.TagField. But then you can also workaround it by having
something like

class LinkForm(forms.ModelForm):
   tags = TagField()
   class Meta:
  model = LinkForm

But you probably have to do some manual work to populate this field
from your views by calling the get_tags() to fill this out?

Just curious on what your experiences are.
