It works! Now whenever users upload an attachment to a workorder/task I can access the file directly from my Evolution To-Do list. The trick(s) were to upgrade to the latest Evolution [3.0.x] and that Vobject automatically base64 encodes the attachment value [so if you do it yourself you end up with base64 encoded base64 encoded data]. The vobject code to pull this off, and make a happy Evolution client, looks like: # ATTACHMENTS if task.attachments: for attachment in task.attachments: print attachment handle = ctx.run_command('attachment::get-handle', attachment=attachment) if handle: data = handle.read() attach = todo.add('attach') attach.encoding_param = 'BASE64' attach.value_param = 'BINARY' if attachment.webdav_uid: attach.x_oracle_filename_param = attachment.webdav_uid attach.x_coils_filename_param = attachment.webdav_uid attach.x_evolution_caldav_attachment_name_param = attachment.webdav_uid attach.x_coils_attachment_uuid_param = attachment.uuid attach.x_coils_attachment_size_param = str(attachment.size) attach.fmttype_param = attachment.mimetype attach.value = data Since I could find this information no where I figured it was worth posting somewhere. <http://vobject.skyhouseconsulting.com/> <https://sourceforge.net/projects/coils/> _______________________________________________ evolution-hackers mailing list firstname.lastname@example.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers
