annotate gpp/downloads/management/commands/dlcatreport.py @ 532:ff67946fd4b0
For #242, move the updating of the POTD sequence into a new signals module.
When photos are deleted from the admin changelist in bulk, the individual
delete() functions on the photo objects is not called. However, the post_delete
signal is called for each object.
