I have a table where I am trying to delete all but the 10 most recent
records. My code is as follows:
cnotes = Channelnote.find(:all, :order => 'tstamp DESC', :limit =>
10, :conditions => ["deleted=0"])
Channelnote.delete_all;
for cnote in cnotes do
g=cnote.save
end
However, it deletes ALL records in the table, seeming to NOT write
cnotes back. Can anyone please explain to me why/ Myu log for this is
enclosed below:
