Instance Method Details

#avatar_url_for(person, options = {}) ⇒ Object

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)
