To use the local adapter which stores files on the same server the Symfony2 instance runs, you have to provide a directory.
# app/config/config.yml
oneup_flysystem:
adapters:
my_adapter:
local:
directory: "%kernel.root_dir%/../uploads"
lazy: ~ # boolean (default "false")
writeFlags: ~
linkHandling: ~
permissions: ~
For more details on the lazy
parameter, take a look at the Symfony documentation.
For the other parameters, take a look at the Flysystem documentation.
