mongoose在insertMany上重复键错误

我想设置我的testing分贝，插入多个angular色项目

... // ADD 3 roles in first group const roleA1 = { _groupId: groups[0]._id, name: 'admin', description: 'can RW group, user', users: [], permissions: permissions1 }; const roleA2 = { _groupId: groups[0]._id, name: 'manager', description: 'can R group, can RW user', users: [], permissions: permissions2 }; const roleA3 = { _groupId: groups[0]._id, name: 'employee', description: 'can R group, can read user', users: [], permissions: permissions3 }; // ADD 2 roles in second group const roleB2 = { _groupId: groups[1]._id, name: 'manager', description: 'can R group, can RW user', users: [], permissions: permissions2 }; const roleB3 = { _groupId: groups[1]._id, name: 'employee', description: 'can R group, can read user', users: [], permissions: permissions3 }; // ADD 1 role in third group const roleC3 = { _groupId: groups[2]._id, name: 'employee', description: 'can R group, can read user', users: [], permissions: permissions3 }; // ADD 1 role wo any group const role4 = { name: 'visitor', description: 'no permissions', users: [], permissions: [] }; return Role.insertMany([roleA1, roleA2, roleA3, roleB2, roleB3, roleC3, role4 ]) .then((insertedRoles) => { console.log('Successfully created test roles in groups'); return insertedRoles; }) .catch((e) => { console.log('Error inserting many: %j', e); return e; }); 

我在roleB2上得到一个重复的密钥。 （name'manager'）…但名称字段在angular色模型中不定义为唯一

  /** * Role Schema */ const RoleSchema = new Schema({ _groupId: { type: ObjectId, ref: 'Group'}, name: { type: String, required: true }, description: { type: String, trim: true, }, users: [{ type: ObjectId }, { _id: false }], permissions: [PermissionSchema] }); 

没有isNew标签被设置。 怎么了 ？

感谢您的反馈意见

UPDATE

mongoose的奇怪输出debug … roles.count被复制…
