Javascript Parse Object Save（）插入重复记录

我有一个带有insert函数的解析应用程序，它在javascript数组上保存一个对象（Audit），然后保存一个子对象（DetailAudit）

问题是，有时此函数会在数据库中插入多个子记录（DetailAudit）

在插入新记录之前，我试图查询子记录是否存在，但save（）方法在实际查询之前执行

插入方法如下所示：

function insert(form,handler){
    var audit = new Audit();
        audit.set("type",Type.createWithoutData(form.auditoria));
        audit.set("folio",form.folio.toUpperCase());
        audit.set("start",moment(form.inicio, 'DD/MM/YYYY').toDate());
        audit.set("end",moment(form.fin, 'DD/MM/YYYY').toDate());
        audit.set("objectives",form.objetivos);
        audit.set("goals",form.alcances);
        audit.set("audits",form.auditores);
        audit.set("auditTest",User.createWithoutData(form.auditorTest));
        audit.set("auditLeader",User.createWithoutData(form.auditorLider));
        audit.set("group",form.grupo);
        audit.save().then(function(audit){
                    var procesos = form.tab;

                    procesos.forEach(function(item) {

                        // Here I tried to query for the existence but didn't work

                        var detail = new DetailAudit();
                            detail.set("process",AuditProcess.createWithoutData(item.procesoId));
                            detail.set("clauses",item.clausulas);
                            detail.set("standar",Standar.createWithoutData(item.estandarId));
                            detail.set("area",Area.createWithoutData(item.areaId));
                            detail.set("auditor",User.createWithoutData(item.auditorId));
                            detail.set("method",item.metodologia);
                            detail.set("comment",item.comentario);
                            detail.set("questions",0);
                            detail.set("grade",0);
                            detail.set("comment",item.comentario);
                            detail.set("audit",audit);
                            detail.save({
                                success:function(detail){
                                    var pros =  new ProcessScheme();
                                        pros.set("title","EQUIPO, INSTALACIÓN Y MATERIALES")
                                        pros.set("content","....")
                                        pros.set("detail",detail)
                                        pros.save();
                                    var pros =  new ProcessScheme();
                                        pros.set("title","ENTRADAS")
                                        pros.set("content","....")
                                        pros.set("detail",detail)
                                        pros.save();
                                    var pros =  new ProcessScheme();
                                        pros.set("title","SALIDAS")
                                        pros.set("content","....")
                                        pros.set("detail",detail)
                                        pros.save();
                                    var pros =  new ProcessScheme();
                                        pros.set("title","INFORMACIÓN DOCUMENTADA")
                                        pros.set("content","....")
                                        pros.set("detail",detail)
                                        pros.save();

                                    var pros =  new ProcessScheme();
                                        pros.set("title","INDICADORES DE DESEMPEÑO")
                                        pros.set("content","....")
                                        pros.set("detail",detail)
                                        pros.save();
                                    var pros =  new ProcessScheme();
                                        pros.set("title","CONOCIMIENTOS, ENTRENAMIENTO Y HABILIDADES")
                                        pros.set("content","....")
                                        pros.set("detail",detail)
                                        pros.save();
                                    var pros =  new ProcessScheme();
                                        pros.set("title","ANÁLISIS DE RIESGO")
                                        pros.set("content","....")
                                        pros.set("detail",detail)
                                        pros.save();
                                },
                            });

                        var audits = [];
                            audits.push(User.createWithoutData(item.auditorId))
                            if(audits.length == procesos.length){
                                audit.set("audits",audits);
                                audit.save();
                            }
                    });

                    sendEmail(audit);

                    handler({status:200,msn:"Auditoría creada exitosamente",res:audit});
            }).catch(function(error){
                    handler({status:500,msn:"Error al crear usuario",res:error});
            });
}

正如我所说，在插入DetailAudit对象之前，我试图查询DetailAudit对象是否存在，但查询总是返回空结果

这个项目刚刚进入我的手中，我对这个解析服务器主题真的很迷茫，任何建议都会有帮助。

您可以创建一个新的主题，以确保集合的唯一性。这将防止重复插入

db.collection.createIndex( <key and index type specification>, { unique: true } )

您还可以使用以下命令通过解析保存多个对象：

Parse.Object.saveAll([arrayOfObjects])

Parse.Object.saveAll([arrayOfObjects])
