我正在构建我的第一个续集模型,因为您可以看到它在创建关联对象时会导致大量嵌套
var values = [],
userAttributes = sequelize.models.userAttributes,
user = User.build(),
name = userAttributes.build({name: 'name', value: 'params.name'}),
fbprofile = userAttributes.build({name: 'fbprofile', value: 'params.fbprofile'}),
phone = userAttributes.build({name: 'phone', value: 'params.phone'});
user.save().then((user) => {
name.save().then((name) => {
fbprofile.save().then((fbprofile) => {
phone.save().then((phone) => {
user.addUserAttributes([name, fbprofile, phone]);
});
});
});
});
我该如何避免这种情况?

Sequelize有一个Bluebird承诺实例。从那里你可以使用Promise.all方法
var values = [],
userAttributes = sequelize.models.userAttributes,
user = User.build();
user.save()
.then((user) =>
sequelize.Promise.all([
userAttributes.create({name: 'name', value: 'params.name'}),
userAttributes.create({name: 'fbprofile', value: 'params.fbprofile'}),
userAttributes.build({name: 'phone', value: 'params.phone'})
])
.then((recordsArray) =>
user.addUserAttributes(recordsArray);
)
);
