Hi!

Im validating name field in "dev" model by checking its uniqueness. but while editing that particular entry, the system again validates for uniqueness of name. so if i dnt change name while editing , it gives me error: name has already been taken.

my update code is :    1. def updateDevice    2. @device=Dev.find(params[:id])    3.
   4. @devtype=Devtype.find_by_id(params[:device][:devtype_id])    5.
   6. if request.post?    7.
   8. @device.update_attributes!(params[:device])    9. redirect_to :action=>"showDevices_admin"   10. end   11.
  12. end

what is the problem exactly?? Thanx in advance! sups
