Question

我正在尝试使用hasMany通过关联使用此处的示例：http://docs.sequelizejs.com/en/2.0/docs/associations/#belongs-to-many-associations

基本上，我的模型是：

User:
User.hasMany(models.Projects, {through: models.Project_User});

Project:
Project.hasMany(models.User, {through: models.Project_User});

Project_User has custom fields:
 status
 is_default

问题是当我尝试使用

添加到此时

 user.setProjects(project).then(function(res){

在插入之前删除之前存在的值之前，它会删除Project_User中的记录。

Executing (default): SELECT status,is_default FROM `Project_Users` AS `Project_User` WHERE `Project_User`.`UserId` = 26;
Executing (default): DELETE FROM `Project_Users` WHERE `UserId` = 26 AND `ProjectId` IN (1726)
Executing (default): INSERT INTO `Project_Users` (`id`,`is_admin`,`ProjectId`,`UserId`) VALUES (NULL,0,873,26);

如何防止DELETION发生???

Answer 1

您应该使用templates/joomlatemplate代替：

addProjects()

sequelize association hasMany通过在插入
