You said that doing @lead.illustration = upload_image (presumably at
this point) did not work. It should do, provided that
params[:lead][:illustration] is not present. If it is then the value
from upload_image will be overwritten by the value from params when
you call update_attributes. Another possibility is that if the
illustration is the only field being changed then update_attributes
may not actually save the record (as it does not think anything has
changed).
Probably leaving it as you have it is the simplest solution.
