Issue

When I edit records that have attachments the file_field is still in the form, this time without any files selected and when I submit the form to update the record all of the previous attachments get removed How can I keep them?

Solution

In a controller, you can restrict the attachment field,

def update
  @object.update(object_params)
end

def object_params
  params.permit(:name, :details,...) #remove attachment field from this list
end

Hope this will help you.
