This is an example RD for a simple service letting people do annotations to some object list through the web interface. It's kept in the docs repo because Markus does not have a live service that could show what do do for this kind of thing. The tutorial assumes this is available at http://docs.g-vo.org/editsample_q.rd for id in range(int(self.sourceToken)): yield dict(zip( ["id", "ra", "dec", "remarks"], [id, random.random()*360, random.random()*180-90, None])) return T.a(class_="buttonlike", href="/\rdId/edit/form?" +urllib.parse.urlencode({ "id": data[0], "remarks": data[1] or ""}))["Edit this"] \internallink{\rdId/view} with base.getWritableAdminConn() as conn: if 1!=conn.execute("UPDATE \schema.objlist" " SET remarks=%(remarks)s" " WHERE id=%(id)s", inputTable.args): raise base.ValidationError("No row for id '{}'".format( inputTable.args["id"]), colName="id") return rsc.TableForDef( self.outputTable, rows=list(conn.queryToDicts("SELECT * FROM \schema.objlist" " WHERE id=%(id)s", inputTable.args))) # or remove the return clause and let this run to redirect # back to somewhere else, like the result display. raise svcs.Found("/\rdId/view?"+urllib.parse.urlencode({ "id": inputTable.args["id"], "__nevow_form__": "genForm"}))
