[newforms-admin] prepopulate_from

[Almir Karic]

i have an error caused by the following line (which worked without
problems on regular django trunk)

slug = models.SlugField("url_prefix",max_length=50,unique=True,prepopulate_from=('name',),help_text='e.g.
"janez_marijan_potokar_novak" (PAZI, SUMNIKI)')

any ideas what am i doing wrong?

<snip traceback>

If you're using newforms-admin, you should read this page carefully:
http://code.djangoproject.com/wiki/NewformsAdminBranch
The particular bit that applies to your code is the section headed
"Changed prepopulate_from to be defined in the Admin class, not
database field classes".
As described there, take the prepopulate_from attribute out of the
model definition and move it into the Admin class, so that it reads:
prepopulated_fields = {'slug': ('name',)}
