hi everyone,
first of all: I'm totally new to django. I did the tutorial and now I
want to go beyond what I've learnt there ... and write a simple app to
manage all my projects in some kind of a archive.
whenever I create a new project via the admin view, a directory with
the name of the project is created in the file system. but in case the
projects gets renamed I also want the directory to be renamed.
how can I compare the old and new value of a field?
in admin.py:
class ProjectAdmin(admin.ModelAdmin):
def save_model(self, request, obj, form, change):
if not change: # new project
os.mkdir("some/absolute/path/" + obj.name_short) # (how
would I use
MEDIA_ROOT here?)
else:
# rename dir from old to new obj.name_short
# but how do I know what value obj.name_short had
before?
pass
obj.save()
thanks a lot in advance!
