awesome... it was all in that [:1]!
now, next issue...
"OperationalError at /admin/galleries/gallery/
(1054, "Unknown column 'galleries_gallery.status' in 'field list'")"
i just added the status field as i wasn't worried about any of that
previously... now, it appears to be causing issues. I've ran syncdb,
but it doesn't seem to be adding this new column. I gather it is very
very important to consider your required fields before syncing
originally... how do i go about fixing this issue?
thanks again
