I'm working on a script to upload a file to a file repository (zope folder) and generate a custom file name. My intention is to use a LocalFS object (instead of the Zope folder) once this bit is sorted. My goal is to rename the file based on the filename and extension variables that I'm passing to the script. The part I'm stuck on is the syntax of this part: manage_addFile(id='%s%s % (filename, extension)', title='', file=file) In this example I'd like to set the id to 'thefile.jpg' TIA, David +++++++++++++ [ script ] +++++++++++++++ #parameters file, filename='thefile', extension='.jpg' """ Uploads a file to the repository with a crafted id.
