# A predictable string to use when generating an input name for this champ.
#
# Rail's FormBuilder can auto-generate input names, using the form "dossier[champs_attributes][5]",
# where [5] is the index of the field in the form.
# However the field index makes it difficult to render a single field, independent from the ordering of the others.
#
# Luckily, this is only used to make the name unique, but the actual value is ignored when Rails parses nested
# attributes. So instead of the field index, this method uses the champ id; which gives us an independent and
# predictable input name.
