Question

我正在尝试在mongodb中创建一个新的集合，给予写入确认权限

我试过这样做

db.createCollection(databaseName, { w: 1 });

但它给我的错误说

MongoError: The field 'w' is not a valid collection option. Options: { w: 1 }

Answer 1

db.createCollection("log", { capped : true, size : 5242880, max : 5000 } )

试试这个并创建集合

db.createCollection("log1", { w: 1} );

这也会创建集合

并检查MongoDB版本

mongoDB 3.4.7错误字段'w'不是有效的收集选项
