Thanks for > the feedback. The way I see it, any good design will end with you setting up separate instances of your code per client. You COULD have a "client id" field in every single model that will be distinguished between clients, but this will be difficult. For one, you're going to need to create a new User model (Totally doable, actually, but a hassle), and trying to maintain all those different clients in the same tables is just begging for mix-ups and errors. As said above, if you use apache, I would try using the worker MPM and mod_wsgi, and just make sure that all your code is thread safe. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: gettext is not defined - js error in admin calendar.js
You have to do like that :
And define in you urls.py
(r'^jsi18n/$', 'django.views.i18n.javascript_catalog', {'packages':
'django.conf'}),
Let me know if it does works :)

Handling Dynamic Image Uploads
Hi, I can't figure out how to handle image uploads in a form that accepts a variable number of uploads. I would happily use Django newforms to take care of it, but I'm using a form that can be extended to include multiple file uploads (implemented by dynamically adding file input tags to the DOM). What are my options? Can I use python in the view to copy the uploaded image from a tmp directory to the file system? To my knowledge, I can't use an UploadedFile object without using form.ImageField or file.FileField in the template. New to Django and loving it - but ran into this bump. Thanks so much!

makemessages create invalid msgid in django.po file
The base language of my site is Chinese. I want to change to English
when user select language perferrence.
In my base.html, I have
{% trans "产品" %}
I generated django.po file using
django-admin.py makemessages -l en
In django.po file of en locale,
#: .\templates\base.html.py:36
msgid "å…¬å ¸äº§å“ "
msgstr "Products"
As you can see, the generated msgid is scrambled and invalid. This
caused translation failed. If I manually changed the msgid to be
msgid "产品"
msgstr "Products"
The translation works. I verified that my base.html is utf-8 encoded.
Anyone know what is the reason for the scrambled msgid in django.po
file? I suspect this is an encoding issue on makemessages command, but
don't know how to resolve this.

You're missing something. You are assuming that setting Foo.id to be None will create a new Bar object. Since "id" is not the primary key of the Bar model, this won't be the case. Your code is creating another copy of Foo and then changes the parent to which the shabda object points. The primary key of shabda doesn't change throughout this process.

You can't really do this without diving deep into the internals of the model creation stuff. Which means you should probably be questioning the approach. If the name and description aren't the same every time, then it's not a common piece of data and doesn't really belong in the abstract base class. Abstract base classes are for data that is the same in every subclass.

First, create an instance of the form using a dictionary of data which should fail, then check that is_valid() is False and inspect the error dictionary to make sure it got the right message.

you can simply create a form on your test case and pass in dictionary
to mimic request parameters. I have blogged about it and you can find

Re: Problem with i18n - "en_US" locale translations coming through for "en"
Hi Fran,
Sorry if I can't help but I've been looking myself for a possibly
quick answer to a strange problem regarding i18n.
I am running latest svn rev and the strangest thing is that in the
admin app I am presented with both LANGUAGES and LANGUAGE_CODE.
My custom templates however do not recognize these variables, even
though they're being passed through the same middleware and context
processors (or at least I'd like to believe that)
Maybe i'm just thinking out loud,
Regards
RiCardo

How can I do it? The model that you are using for the m2m relation is just another model, so if you want to modify an instance of that model, select an instance it and change it directly. >>> p = person.objects.get(name='Juan') >>> r = relation.objects.get(person__name='Juan', instrument__name='Djembe') >>> tamb = instrument.objects.get(name='Tambourin') >>> r.instrument = tamb >>> r.save() Also - as a matter of style, it's a good habit to get into the capitalization scheme suggested by PEP8 [1] - that means that class/model names should be captialized (i.e., class Person, not class person) [1] http://www.python.org/dev/peps/pep-0008/ Yours, Russ Magee %-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Or possibly a change to PostgreSQL 8.3 from something earlier. This could
be the result of the change "Non-character data types are no longer
automatically cast to TEXT" described here:
http://www.postgresql.org/docs/8.3/static/release-8-3.html
This was "fixed" (by Django code automatically adding a cast) for
search-type lookups (like, contains, etc.) per this ticket:
http://code.djangoproject.com/ticket/6523
But that change doesn't affect equal lookups, which is what you are doing.
The SQL shown actually looks like the PostgreSQL change may be exposing a
latent bug in your code. 'category = 0' rather sounds more like it should
be 'category = ""' or 'category is null'. I'd take a look at the code
causing that SQL to be generated and see if it is really doing what you
intend it to.

Get m2m id to update the m2m model.
Hello, I try to update a m2m relation. So this is the problem: models.py --- from django.db import models class instruments(models.Model): name = models.CharField(max_length=10) class people(User): objects = UserManager() phone = models.CharField(max_length=9, blank=True, null=True) movil = models.CharField(max_length=9, blank=True, null=True) class relations(models.Model): person = models.ForeignKey(people) instrument = models.ForeignKey(instruments) def __unicode__(self): return '%s => %s' % (self.person, self.instrument class concerts(models.Model): title = models.CharField(max_length=80) date = models.DateTimeField() description = models.TextField() musicians = models.ManyToManyField(relations, blank=True, null=True) def __unicode__(self): return self.title If I add some concerts with musicians, and I need to change the relation of the person with the instrument. I think updating the relations class using the id to update the instrument. How can I get the IDs of the relations associated to the m2m (musicians) field? If I use: >>> from my_project.test.models import concerts, relations, people, instruments >>> b = concerts.objects.get(id = 2) >>> b.title u'Test2 Concert' >>> b.musicians.all() [ Djembe>, Tambourin>, Djembe>] But I want to change the relation 'Juan => Djembe' to 'Juan => Tambourin'. How can I do it? Thank you very much. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Keeping track of song play count in django and flash
i'm looking at this problem too. 1. either the flash player can send a javascript/ajax ping to a url where it can be logged 2. or the songfile can be a django served url which logs and then redirects to the actual static URL. probably the second is easiest.

Since you're running different versions, have you looked at the
backwards incompatible changes page? This issue is described there:
http://code.djangoproject.com/wiki/BackwardsIncompatibleChanges#Removeddictionaryaccesstorequestobject
Basically, you can no longer do request['key'] to get a value from the
request object, or request.has_key('key'). You have to do
request.REQUEST.has_key('key').

This sounds like a difference in the way your database is set up. Are
you sure you have the same table definitions, collations, charsets,

Re: Possible pug with Model inheritence - Inserts instead of Update
ah ok. you will have problems here because the parent class also has a database record and an id. it would be messy I think to try to fool django. better would be to make a kind of save_as or maybe you can copy the object and it will also copy its parent class. or make a specific method for this class that returns a clone with just the fields you want to copy for the history. there is some pluggable app called "django-versions". check this out and see if it works for you. -f;lix On Oct 12, 8:23 pm, shabda <[EMAIL PROTECTED]> wrote: > As long as model_obj.id is None, Django does an Insert, I want an > insert to happen all the time.

Attachment not recognized as such in EmailMultiAlternatives email
Hi, When I create a EmailMultiAlternatives email and attach a PDF attachment after having provided both a text and HTML body the PDF attachment is not recognized as such by an email client (although the text and HTML representations are correctly displayed). It looks like the EmailMultiAlternatives email does not include an mulitpart/mixed wrapper arround the multipart/alternative views. Any suggestions? Is this intentionally or a bug?

That means nobody who read the list yesterday and had time to answer questions knew the answer. Asking the same thing again isn't particularly helpful to anyone. Instead of reposting, did you consider doing some independent research? I've never run Django on Jython but a simple Google search on "Django Jython mysql" reveals this project as the 1st hit: http://code.google.com/p/django-jython/ It apparently has PostgreSQL and sqlite backends, and lists MySQL as "Should be easy to implement" here: http://code.google.com/p/django-jython/wiki/DevelopingNewDatabaseBackends So it doesn't appear there is a mysql backend for Django on Jython available at the moment. Further investigation of the Google hits reveals at least one blog of someone who maybe started on one, so that also might be a place to look further.

Custom form/formset for edit inline
Hi, I'm trying to figure out how to use a custom form for when editing objects inline in the admin. The case is something like this: I have Images that have foreign keys to image galleries. When editing a gallery, the images associated with it are edited inline. The image model has quite a few options, so the listing on each gallery page gets pretty long. Images also have a field for sorting weight. I would like to implement simons snippet for sorting inline objects with drag and drop (from http://www.djangosnippets.org/snippets/1053/), which is pretty unusable with a very long page. I would therefore like the image form to collapse, showing only the ordering field, title and hopefully a thumbnail of the image. I know I could probably do this via a custom template, but that felt a bit messy for some reason. So, I decided to take a shot at learning a bit about customizing the admin form stuff via formset factories. I tried reading the docs, googled a bit but couldn't get it working. So far I've done the following: 1. Create a normal ModelAdmin-subclass for both Image and ImageGallery 2. Created a ModelForm-subclass for the galleries to get the extra JS stuff in to get the draggable stuff working 3. Created an ImageInline (subclass of admin.StackedInline) 4. Pointed to the ImageInline from the ModelAdmin options for ImageGallery 5. In the ImageInline-class, I specified the formset-option, pointing to... 6. ...the ImageInlineFormset, which a formset created with inlineformset_factory, that in turn specifies a form in the function call, namely... 7. ...ImageInlineForm, which is a subclass of ModelForm. There, I've specified exactly how I want my fieldsets laid out. My admin.py is up at http://dpaste.com/83994/ Nothing seems to take in changing the inline form for the image though. I get no errors, but the form stays the same... I'm not 100% sure about everything I'm doing every step of the way here, so... Have I got all this backwards? I just assumed that since I can specify a formset-option on the inline, I should be able to use a formset created through inlineformset_factory, and, in creating that, pointing to a custom ModelForm... //emil --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

order_by on a QuerySet translates to 'ORDER BY' in the SQL SELECT sent to
the database. So you have to order_by something known to the database. You
can force the calculation & result to be part o fthe SQL select and thus be
something you can specify in order_by by using extra():
Thing.objects.extra(select={"calcz" : "x / y * %d" %
A_CONSTANT},order_by=["calcz"])
Whether that's "best" depends on how complicated your actual computation is,
how many rows you have in your table, how often you do this select vs.
update rows, etc. Alternatively you could store z directly in the database
and avoid having to do the computation for every row when you do the
select. But then you have to ensure z stays in sync with changes to x & y.

Re: Possible pug with Model inheritence - Inserts instead of Update
As long as model_obj.id is None, Django does an Insert, I want an insert to happen all the time. (Sort of like trying to get FullHistory, wherein I can roll back my object to a previous state.

Ordering object collection by computed field?
Hi!
I have a model like this:
class Thing(models.Model):
x = models.PositiveIntegerField()
y = models.PositiveIntegerField()
def z(self):
return self.x / self.y * A_CONSTANT
In a view I would like to retrieve a collection of Things ordered by z
(the computed field). I expected the order_by method to do the trick
like this:
things_collection = Thing.objects.order_by('z')
...but order_by will only work for fields actually stored in the
database (the above gives a "Cannot resolve keyword 'z' into field").
What would be the best way to implement a custom order_by that allows
ordering of computed model fields? Or have I missed some feature for
this in Django?

Peter

DEFAULT_CHARSET doesn't really matter here since it has nothing to do with
the database or communicating with the database. See:
http://docs.djangoproject.com/en/dev/ref/settings/#setting-DEFAULT_CHARSET
It's used for encoding HttpResponse objects, not for database communiction.

This is odd. MySQLdb appears to be using latin-1 for the connection
charset, yet Django always sets the connection charset to utf8, see:
http://code.djangoproject.com/browser/django/tags/releases/1.0/django/db/backends/mysql/base.py#L242
Somehow that is being overridden or is not working on your machine. Have
you specified anything in DATABASE_OPTIONS in your settings.py? What
version of MySQL are you using?

Re: Possible pug with Model inheritence - Inserts instead of Update
well this is interesting and curious what you are trying to do. why are you trying to do this self.id= None ? what is the real world purpose ? can you give a non abstract example ? in any case since Bar is a subclass of Foo there are two database tables. you set Bar id to None, but the object still has a Foo ptr id, so ultimately there is still only one object. that is, I think, the primary key that is accessed when using Bar.objects.all() really, you have broken it by this self.id = None, so I would expect more problems On Oct 12, 9:16 am, shabda <[EMAIL PROTECTED]> wrote: > My models.py > > class Foo(models.Model): > name = models.CharField(max_length = 100) > > def save(self): > self.id = None > super(Foo, self).save() > > class Bar(Foo): > created = models.DateTimeField(auto_now_add = 1) > > This gives me, > > In [1]: from djcalendar.models import Foo > > In [2]: shabda = Foo(name = 'Shabda') > > In [3]: shabda.save() > > In [4]: Foo.objects.all() > Out[4]: [] > > In [5]: shabda.name = 'Shabda Raaj' > > In [6]: shabda.save() > > In [7]: Foo.objects.all() > Out[7]: [, ] > > Which is what I expect.

Re: Why does MySql gives warning? Incorrect string value: '\xE6\x9D\xB1\xE8\xA8\xBC...' for column 'title' at row 1
thanks too for this. rather than alter the table manually of course, it should have been created correctly the first time. mysql will create new tables with the character encoding of the database. you can set that this way: alter database cruxxial_md CHARACTER SET = utf8; now tables created with syncdb will have the correct encoding. mysql will create new DATABASES with the charset that was used to start the server mysqld --character-set-server=utf8; which is often out of our control on hosted environments, or even when using handy os x control panels to start the db. so I guess a tip is : when you create the database, make sure to alter the charset before running syncdb. but what does the unittest runner do ?? (since it creates its own database) it also creates a latin1 db: CREATE TABLE `website_releasefeedback` ( ... ) ENGINE=MyISAM DEFAULT CHARSET=latin1 I wonder if django should create all tables with UTF-8 regardless of how the db is configured.

Re: Blank and null values for a foreign key
Fabio,
If you define de foreignkey in the license model, you can create persons
without a problem. The only requirement then for creating a license would be
that it needs an existing person. Something like this:
class Person(models.Model):
name = models.CharField(max_length=30)
class License(models.Model):
person = models.ForeignKey(Person)
number = models.IntegerField(max_length=10)
Regards,
Gerard.

Thanks a bunch. I've solved this a couple times before on this list, so you might find either of these two threads (and the python code for creating a corresponding columnize template filter) useful: http://groups.google.com/group/django-users/browse_frm/thread/b5f531e2aba49b4a/ http://groups.google.com/group/django-users/browse_frm/thread/a9ca56a9f601271a/ It also allows you to tweak the values returned for the "empty" cells when it squares it off (your content of your last two nodes), so you can pad with the empty string, or you can use something like " " as your padding.

Better still, see

which may well have solved this problem for you in a tidily-packaged way.

You appear to have an error in your own code, as evidenced by the final line of the traceback (when in doubt, always *read* the error message): "Tried view_form in module px.heroes.views. Error was: 'module' object has no attribute 'view_form'" This says that your code tries to access something named "view_form" in the module "px.heroes.views", but that there is no such thing available. This raises an exception, which breaks everything. (and the reason why you see this in the admin is because the admin uses reverse URL resolution, which means it has to be able to import all of your views -- any error, anywhere, in any of your views, will break everything) -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Blank and null values for a foreign key
Hi all!
I have two models, Person and License.
class License(models.Model):
number = models.IntegerField(max_length=10)
class Person(models.Model):
name = models.CharField(max_length=30)
license = models.ForeignKey(License,verbose_name="Centro di
costo",blank=True,null=True)
class PersonAdmin(admin.ModelAdmin):
list_display = ('name', 'license')
ordering = ('name','license')
list_filter = ('name','license')
As you can see, a new person can be added with no license at all:
"blank=True,null=True" options. That's what I want.
In my admin panel I get the list of all the persons I have added. I
wish I could filter or order this list so that I get all the persons
that have no license.
The point is, if I use "blank=True,null=True" I'm not allowed to have
this filtering/ordering in my admin panel. (The table I get in the
admin panel can't be ordered by the column "license".)
If I only use the "blank=True" option, then I am allowed to order by
license but no "empty" values are then allowed when adding a new
person. This way, each person must have a license, which is not the
case.
Well, I guess I could use a not-existing license number instead of
null. For example 00 instead of NULL. But it seems tricky and
I might need that number in the future.
How can I solve this?
Thanks, Fabio.
