For testing set
|
|
Synchronization server that is syncing published files from local to
|
|
any of implemented providers (like GDrive, S3 etc.)
|
|
Runs in the background and checks all representations, looks for files
|
|
that are marked to be in different location than 'studio' (temporary),
|
|
checks if 'created_dt' field is present denoting successful sync
|
|
with provider destination.
|
|
Sites structure is created during publish and by default it will
|
|
always contain 1 record with "name" == self.presets["active_site"] and
|
|
filled "created_dt" AND 1 or multiple records for all defined
|
|
remote sites, where "created_dt" is not present.
|
|
This highlights that file should be uploaded to
|
|
remote destination

Each Tray app has assigned its own self.presets["local_id"]

Tray is searching only for records where name matches its

|
|
"active_site" could be storage in studio ('studio'), or specific
|
|
"local_id" when user is working disconnected from home.

If the local record has its "created_dt" filled, it is a source and

process will try to upload the file to all defined remote sites.

Remote files "id" is real id that could be used in appropriate API.

Local files have "id" too, for conformity, contains just file name.

It is expected that multiple providers will be implemented in separate

classes and registered in 'providers.py'.
