Re: Migrating older 1.4 project to 1.9
As stated above, take small steps. Take the time to read the release notes for each minor version. Most of the minor versions are bug fixes and you can scan through them. Pay close attention to migrations if using South. In Django 1.7 South is not used. Django incorporated migrations into the core code. In Django 1.6 you will add code to settings.py to prepare you for Django 1.7 migration format (if using south). Each third-party installed app will also have specific requirements if upgrading from South. Read the docs for each installed app. I am in the process of updating four Django 1.5.5 / DjangoCMS 2.4.3 applications. It is a painful time consuming process. I am documenting what I am doing to publish for others but it seams each application has its own upgrade propblems. -- You received this message because you are subscribed to the Google Groups "Django users" group.

obtaining related object from django.db.models.fields.related.ForeignKey
Hi all, from a model object, I can get a related object shortcut, using the name of the foreign key field: >>> m1 = Mailbox.objects.get(pk=38) >>> str(m1.localdomainfk) 'framailx.de' But if I have the foreign key field instead of its name, I can only get the pk of the related object: >>> f1 = Mailbox._meta.get_field(‚localdomainfk') >>> f1.value_from_object(m1) 7 Can anybody show me, how to get the related object shortcut, if I have only the local object and the foreign key field?

Looking for ways to improve my skills
Hi All, I have been working with Python for just over 3 years now and have recently taken up django. I have completed both the polls app and have created an address book app by following a tutorial on youtube. I am looking fro ways to improve my competence with django and possibly some end to end website projects. Can anyone provide me with some links as to where I could find resources for improving my skills and then avenues for using these skills to generate income? Thanks in advance.

django-extensions: dumpscript/runscript manytomany with through= broken?
Hello, I was wondering if anyone knows a good way to handle restoring a backup taken with a m2m intermediary model. I'm trying to upgrade from my sqlite database to a real database and would like to keep the data that was created thus far. Basically the models look like this: class Message(models.Model): subject = models.CharField(max_length=64) ... recipients = models.ManyToManyField(User, through='SentRecord', blank=True) class SentRecord(models.Model): message = models.ForeignKey(Message) recipient = models.ForeignKey(User) sent_at = models.DateTimeField(auto_now=True) So I've tried both dumpdata/loaddata and dumpscript/runscript. The former basically quietly ignores the records but everything else is OK -- but no Messages or SentRecords. So I've tried two approaches -- first problem was regarding the fact that SentRecord and Message refer to one another and so one has to be created first. dumpscript picked SentRecord to do first -- totally sensible. But It can't comply with the above model because the .message foreign key will create a column that enforces NOT NULL. OK fine, I changed the above model to allow null on message, since it basically does this sequence: 1. create sent messages, with no message pk 2. create messages 3. then it *should* fill in the sent messages .message pk... but instead it blows up because because it generates stuff like this: app_message_1.recipient.add( importer.locate_object(User, 'id', 1, ... Which is a big no no because of the through record it's using wrong manager. It should be getting the sent records already created and setting the .message pk on those instead of trying to add Users directly to the message, as though it were a regular m2m. I'm just wondering if anyone knows if this is a fixed issue and I'm just 'holding it wrong'... otherwise I'll be faced with some stark choices, fix django-extensions to get my way... or do some ugly sed/awk to patch it up.
