For use with the FileColumn Rails plugin.
Returns nil if person is nil; otherwise, returns the (possibly nil) result
of url_for_image_column
, passing in all of
options
except :file_column_field. Options:
:file_column_field
- the image file column within
person
; by default, :avatar
:file_column_version
- one of the versions of the file_column;
no default
If :file_column_version is not specified, all other options are passed to
url_for_image_column
as options
(see
FileColumnHelper)
