Upload Images to Existing Records' Attachment Field in Bulk
Hi,
I had such task for thousands of images, and upload files to the record is limited to 1000 files.
So I wrote script for that to run from button, which uploads all files loaded to 'Files' field.
The script asks table to load and field to read file names. After completion, it cleans 'Files' and if any files left 'orphaned', you can review and check.
The toughest part was - to check whether part of files are already existing in table, so they won't be uploaded. If you have duplicate file names, script possibly will load them to the first record, where it found such name. I had unique names for all files, so I hadn't test such scenario.
preparation: you need to create the table 'uploader' with 'Files' - attachment field, 'Status' , single-select with options 'LOADING' and 'idle' and button to run script.
I had no time to add 'Status' field detect/auto-create and to make the better readable code, and I won't have such tasks in future plans, so I just can share it 'AS IS'
