Creating an object with a FileField programmatically
Hello,
I want to be able to add files inside a model to test that model.
However, I'm unable to find in the documentation any mention on how to
do so. I asked on IRC and somebody suggested the following:
from django.core.files import File
from myproject.myapp.models import MyModel
fd = open('/path/to/file')
f = File(fd)
obj = MyModel.objects.create(file_field=f)
f.close()
fd.close()
However, when I try to access obj, I get the following exception:
SuspiciousOperation: Attempted access to '/path/to/file' denied.
Is it how one is supposed to "attach" file into a model? If so, what
could be causing my problem?
Thanks,
Vincent

What happened to the template engine in SVN?
Hello, I have been looking at the Jinja templating engine lately to be used in our web sites. Their web site claims that it is in average three times faster than Django's templating engine. I decided to see that for myself by designing a few, simple test cases. The biggest surprise came not from the fact that Jinja was faster, but how much slower the Django SVN template engine was compared to the Django 0.96 engine. I have posted the result as an Excel chart here: http://www.flickr.com/photos/[EMAIL PROTECTED]/2363195045/ Could anyone tell me if they have similar experiences with the latest Django builds?

ManyToMany fields in database lookups
Hello, I have a curious problem with a complex filter in 0.96: Merchant.objects.filter(Q(categories_fr__name__icontains=s) | Q(categories_en__name__icontains=s)) this returns an empty queryset even when 's' is in categories_fr. Changing categories_fr__name with an attribute directly in the object has the same effect. It seems that a ManyToMany field with no elements nullifies the entire query. Is this a bug, or am I misunderstanding something? Thank you, Vincent. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Generalizing media files URLs
Hello,
My coworker and I have a sizable Django project called Gestio. We're
pretty much done writing it, so now we're making sure that it'll work
without hitches wherever we may install it. Thanks to the {% url %}
tag, we can choose to place the application under /, /gestio, /webapps/
gestio or whatever, the URLs are dynamically resolved. The same
cannot be said for media files however.
We are trying to come up with a general and simple way to refer to
static files, but so far, we haven't come up with anything we like.
Here are some things we considered:
1. Writing our own {% media_file "images/foo.png" %} tag. The problem
is that tags are not embeddable in other tags, so we couldn't use some
of our other tags (e.g.: {% icon {% media_file "images/foo.png" %} %})
2. Using {% url %}. Same problem as above, but with the added down-
side that the tags code would be even longer.
3. Concatenating MEDIA_URL with the image file (e.g.:
{{ MEDIA_URL }}images/foo.png) This is very ugly IMHO, because the
two parts of the URL are not visually "connected". If braces are
involved, I'd rather have all my information inside rather than a
little inside and a little outside.
4. Using a filter such as {{ "images/foo.png"|media_file }}, but this
is pretty ugly. It would however work in tags and keep everything in
braces. This is currently the best solution I can think of.
If anyone has other ideas or experience with this particular problem,
please share!
Thanks,
Vincent.

Multilingual site best practices
Hello,
I work for a company who develops web sites and web applications for
clients in Quebec. People in Quebec mainly speak french, but there
are english speaking people too. Most sites we make eventually want
to have a french and english version with french being the "main"
version.
I would like to know if anyone could share best practices for
multilingual sites. I also have some questions:
1. In the {% trans %} and {% blocktrans %} tags, should I include the
full text, or just a quick description and enter the full text in
the .po files?
2. As I said, french is the main language in Quebec, so if I write a
site in french and am later asked to translate it, will the accented
characters cause a problem if they're used in the msgid of the .po
files?
3. It seems the server always has to be restarted after the .po files
have been compiled. Is that so? If I don't have root access to the
server to restart Apache, is there a way I can have the new
definitions appear on the site?
Thanks for the input,
Vincent.

SQLite + float vs MySQL + Decimal
Hello, I found a curious problem in my application when I put it into production this week: when a models.FloatField is "extracted" from the database, its type changes depending on the database. With SQLite in development, I got back floats, while on MySQL in production I have decimals. As mentionned in other posts, decimals are not serializable in JSON. We are using Django 0.96 (and have no intention to use the Subversion branch.) Is it possible to fix the problem without applying a patch? I don't have root access to the production environment, so I can't apply patches. Vincent. >>> # Development environment w/ SQLite >>> from gestio.inventory.models import * >>> import django >>> type(Item.objects.all()[0].loss) >>> django.VERSION (0, 96, None) >>> >>> # Production environment w/ PostgreSQL >>> from gestio.inventory.models import * >>> import django >>> type(Item.objects.all()[0].loss) >>> django.VERSION (0, 96, None) >>> --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Will Django.core.validators remain stable
Use validators in newforms.
class MyForm(newforms.Form):
secret_phrase = newforms.CharField(label='Secret phrase',
required=True)
def clean_secret_phrase(self):
if self.cleaned_data.get('secret_phrase') == 'xyzzy':
return True
else:
raise newforms.ValidationError(u'This is not the secret
phrase.')

Re: Object list generic view + list
My problem is that I need to sort on a field in a another table. I
found a workaround:
File.objects.select_related().filter(...).order_by('app_table.column')
It works for me because the foreign key cannot be NULL.

Re: Hard-coded sting in IFEQUAL
It works fine with me:
>>> from django.template import Template, Context
>>> t = Template('''{% ifequal s "Some Thing" %}Equal{% else %}Not equal{%
>>> endifequal %}''')
>>> t.render(Context({'s': 'foo'}))
'Not equal'
>>> t.render(Context({'s': 'Some Thing'}))
'Equal'
What version of Django are you using?

Re: Developing without tempplates
There's more than one way to do it (with apologies if you don't like Perl). One thing I like to use is IPython which allows you to start a Python interpreter from any point in your code with the entire context. So to test a function, you could add the following lines at the bottom of the function body: from IPython.Shell import IPShellEmbed IPShellEmbed()() When this point is reached, you will have a complete interactive Python interpreter to play around with your variables. Another way would be to use the pprint module (standard in Python) to display only the variables you want.
