Thanks Dave,
below is a version of the code as is, inches a variant of what you
suggested I think...
#
-------------------------------------------------------------------------------
@auth.requires(auth.has_membership(role='super'))
def del_op_audios():
try:
# Before we delete the db references, find the uploaded file
name/path
#
upload_path_name = db.audios.the_file.uploadfolder
#try to get the name of the uploaded file (not original file)
# - what does this need to be???
# print db.audios.the_file and you get a sensible filename, e.g.
"audios.the_file.87f39e4b2eac56a2.7331343035323830332e706466.mp3"
# but I don't seem to be able to get that name as a string to
pass to os.path.join????
upload_file_name = db.audios.the_file.??????? or ??????
print(f'upload_file = "{upload_file_name}"')
print(f'upload_path = "{upload_path_name}"')
# since we've got record_versioning turned on, we can't truly
delete the record
# with a "del db.audios[request.vars.record_id]"
# so go directly to db and delete the record
# - Relying on the SQL CASCADE being enabled
#
db.executesql(f'DELETE FROM audios WHERE
id={request.vars.record_id};')
# Commit the changes
db.commit()
# Now that the record is gone, delete the associated uploaded file
# something like this ...
#
os.remove(os.path.join(request.folder, upload_path_name,
upload_file_name))
session.op_result = 'Success - DELETE successful'
except Exception as why:
session.op_result = f'Failed - {why}'
redirect(URL('default', 'list_all_rows'))
What am I missing?
