Sequelize.js how to show error on create when using the .on("error") syntax? -

-

I am trying to explain how to pass the client due to the failure of creation.

I am using the recommended status code and I want to add details to the X-ray-ridge header. But when I use the "(") syntax, how do I pass the fault object in the callback function

thanks 

  player.create ({name: Req.body.name, fname: req.body.fname, email: req.body.email,}). Console log ('player creation worked!'))) .on ('error', function (player1) {'success', function (player1) {res.status (201) .jsonp (player1) Res.header ("X-status-reason:", "Where's my err.description?"); Res.status (400) .jsonp (player1); console.log ('an error in player creation')})  
 
 First error error codeback should be  error ,  Player1  
 
 )

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
