def render_ms_excel_2003_xml_for_download(scoped_collection,
attributes,
column_headers,
filename=nil)
klass = scoped_collection.klass
if klass.superclass == AbstractSmarterModel
column_types = klass.attribute_db_types
else
column_types = {}
attributes.each do |attr|
column_types[attr] = klass.columns_hash[attr.to_s].type
end
end
filename ||= "#{klass.model_name.human.pluralize}"\
" #{Time.now.in_time_zone.strftime('%Y-%m-%d
%k_%M')}"\
".excel2003.xml"
send_data render_to_string(
:template => 'shared/index',
:locals =>
{ :models => scoped_collection,
:attributes => attributes,
:column_types => column_types,
:column_headers => column_headers}),
:filename => filename,
:content_type => "#{Mime::MS_EXCEL_2003_XML.to_s}; "\
"charset=utf-8",
:disposition => 'inline'
end

I use `render` together with `send_data` here only because i've found no
way to specify the default file name with `render`.

Thanks for an opinion.
