Re: Track "before" and "after" state of an object when editing in the Admin?
I had a very similar problem where I needed to track all changes to models throughout the entire application. I've posted my solution at http://pastebin.com/2Wc4Nwcd for you to take a look at. Basically, as was previously suggested, I've hooked into the various pre_*, post_* and m2m_changed signals that are available. My code will log all changes to models unless the model is included in a DONT_LOG_MODELS tuple in the app settings. Changes to m2m relationships are stored against the model containing the m2m. Hope this helps. Cheers, Tony -- You received this message because you are subscribed to the Google Groups "Django users" group. To post to this group, send email to django-us...@googlegroups.com.

Re: Use Subversion to Download the Latest Django Version
TortoiseSVN is a graphical SVN client. If you right-click you should see an option for Tortoise that, when expanded, contains a check out option. From there, just follow the wizard.

Can a model generate custom SQL when loading/saving a field?
I'm running into a bit of a problem with Django's models. I have a VARCHAR field that needs to be stored with the content AES_ENCRYPT then HEXed (done on the MySQL server). What I'd like to have happen is for the Django model to generate "AES_DECRYPT(UNHEX(field), salt)" when the field is loded by the model and "HEX(AES_ENCRYPT(field, salt))" when the field is saved by the model. Is there a way to make this happen, so far I'm not turning up anything. Cheers, Tony Czeh -- You received this message because you are subscribed to the Google Groups "Django users" group.
