sequelize findOrCreate with include assoication

Question

使用sequelize,我有两个关联模型:

var Assessment = sequelize.define("Assessment", {
  name: DataTypes.STRING
});

var User = sequelize.define("User", {
  sid: DataTypes.STRING
});

Assessment.belongsTo(User);
User.hasMany(Assessment);

在一些应用逻辑之后,我有一个User:

User.findOrCreate( { where: {sid: "123"} } ).spread(function (user, created) {
  // user is a User
});

在这一点上,我不能得到sequelize关联用户作为一部分Assessment.findOrCreate.此代码将在数据库中创建一个新的评估记录(如果不存在),但它不会将用户密钥作为记录的一部分包含在内(而只是它只是NULL):

Assessment.findOrCreate( {
  where: { },
  include: [ { model: User, where: user.primaryKeyValues } ]
} ).spread( function (assessment, created) {
  // ...
});

---

我有一个解决方法,通过添加:

assessment.setUser(user).then( function(assessment) {
   ...
});

...但是,这会导致SQL UPDATE只是创建记录的一部分.我相当肯定应该有办法做到这一点,但无法在docs/so/etc中找到任何东西.

试试这个：您需要将User主键引用设置到创建的评估中。

Assessment.findOrCreate( {
  where: { UserId: user.id },
  include: [ User ]
} ).spread( function (assessment, created) {
  // assessment should contain a User property with the previously found / created user
});
