I am using the following tutorial to upload images to "Files" pre defined collection.
http://devcenter.appery.io/tutorials/...
My design requirement is that I need to automatically update the file name to something with a specific tag. I've tried to modify the request of the db__file_upload_service and added "File Name" parameter. Then I've added a JS to the "File Name" parameter in request"
return 'foo_bar_';
The file/images are getting successfully uploaded, however, the name is never what I want (but is some default file name code that Appery uses).
How can I add a custom name to file while it's being uploaded?
