File replacer mix-in
Hey. I needed a fix to make some (but not all) models in an existing app delete the previous content of a FileField after update. I figured out a workaround, but should I be wary of anything with this implementation, or is there a better way to do it? Thanks. -Mick. from djano.contrib.contenttypes.models import Model class OrderedModel(Model): dev save(self): # Some custom save code to facilitate ordering class FileReplacerMixin(): def save(self): # Code to check each FileField for changes and delete as appropriate. # Now I can have Ordered or Unordered models which # either replace files or keep the previous content around, such as: class OrderedModelWhichReplacesFiles(OrderedModel, FileReplacerMixin): def save(self): # Call the mix-in to replace files FileReplacerMixin(self) # Call the parent class's save function super (OrderedModelWhichReplacesFiles, self).save() -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: v1.2 message framework - messages created outside of the request cycle
I've encountered same issue. My solution is simple model and
middleware:
class OfflineNotification(models.Model):
user = models.ForeignKey(User)
message = models.TextField()
level = models.PositiveSmallIntegerField(default=20)
created = models.DateTimeField(auto_now_add=True)
class OfflineNotificationsMiddleware:
def process_request(self, request):
if request.user.is_authenticated():
notifications =
OfflineNotification.objects.filter(user=request.user).distinct('message')
for notification in notifications:
messages.add_message(request, notification.level,
notification.message)
if notifications:
OfflineNotification.objects.filter(user=request.user).delete()
Hope it will help you.

Re: Chat
If you are using XMPP (which I do recommend) you'll want to check out the JS library Strophe (http://strophe.im/) which handles XMPP over HTTP. You will still need a server side BOSH endpoint, either a connection manager that allows you to connect to existing xmpp servers, like gtalk or jabber.org. https://github.com/twonds/punjab Or use the built in support for BOSH in Ejabberd, or Openfire. An example of django + strophe +ejabberd project is speeqe.com It is a multiuser chat site.

Re: Serving static/dynamic files under same suburl
Nginx can test to see if a file is available, and if it exist load that instead
of proxying the request to django.
location / {
alias /var/www/static/;
if (!-f $request_filename) {
proxy_pass http://127.0.0.1:8000;
}
}
Now if /var/www/static/foo.js exists, but /var/www/static/bar.js does not
foo.js will be served as a static file by nginx and the bar.js request will be
passed to django where you can use a template to dynamically serve it.

Re: oAuth 2.0
First are you trying to preform actions on the user's behalf on a thrid party site, or are you trying to authorize third parties to take an action on behalf of a user of your site? (are you a Client or a Server in this case?) if you are a Client you need to request a request_token for the service you are authenticating with, redirect the user to an authorization url for them to login/authorize you, and then exchange the request token for an access_token. That is what the python-auth2 django example code does. If you are a Server wanting to hand out keys to authenticate your service's users, there is a Server class in python-oauth2 that will be very helpful (especially in checking request signatures) But I dont know of any example django code (Someone else might). _Mick On Thursday, March 3, 2011 at 2:51 AM, Олег Корсак wrote: > Yes.

python-oauth2 doesnt support generating new tokens, just verifying based on
them. It is up to how you want to generate tokens, and where to store them.
Perhaps use the uuid module built into
python(http://docs.python.org/library/uuid.html), or some other way of creating
unique strings. some people (twitter) like to include the account id in the
token, which certainly helps debug at times, but isnt at all needed.

Re: ManyToManyField and get_or_create
I have the same problem, looks like it's a bug: https://code.djangoproject.com/ticket/18896 On Friday, 31 August 2012 18:55:39 UTC-4, Matt Long wrote: > > Bump? > > Almost exactly 4 years later, I've ran into this exact same issue in > Django 1.4.
