Hi there, i hope you'll are good. I have the follow question: I have a form to storage imagen to s3 and that works pretty good: However the problem is i need to update the routes of those images in other for id and route column. It works nice when i want to save the route in the table of the resource. but if is another table and i would need the id of the resource i am saving the images? how can i do that? Basically. save the routes of the images in another diferente table of the resource i am using to storage images to s3.
