Question

我有多个模型合作伙伴， PartnerUsers ， ContentRequest 和 UserContents 。

协会就像

// Association between Partner & PartnerUsers
m.Partners.hasMany(m.PartnerUsers);
m.PartnerUsers.belongsTo(m.Partners);

// Association between PartnerUsers & UserContents
m.PartnerUsers.hasMany(m.UserContents);
m.UserContents.belongsTo(m.PartnerUsers);

// Association between Partner & ContentRequests
m.Partners.hasMany(m.ContentRequests);
m.ContentRequests.belongsTo(m.Partners);

现在我正在使用急切的加载，我不知道如何使用多个预先加载。我这样做

Partner.find(
  where: {
    id: id
  },
  include: [PartnerContents, ContentRequests],
  include: [{
    model: PartnerUsers,
    include: [UserContents]
    }]
  )
  .success(function(partner){ 
  })

但是没有给我 partner.partnerContents＆amp; partner.contentRequests

我有** patner.partnerUsers [0] .userContents **

如果我这样做的话

Partner.find(
  where: {
    id: id
  },
  include: [PartnerContents]
  //include: [{
  //  model: PartnerUsers,
  //  include: [UserContents]
  //  }]
  )
  .success(function(partner){ 
  })

我有 patner.partnerContents

建议我如何通过协会获得所有三个，例如 patner.partnerContents，patner.contentRequests和patner.partnerUsers [0] .userContents

Answer 1

请参阅documentation options.include

检查一下：

Partner.find({
    where: {
        id: id
    },
    include: [
        PartnerContents,
        ContentRequests,
        {
            model: PartnerUsers,
            include: [UserContents]
        }
    ]})
    .success(function(partner) {

    });

包含在sequelizeJs中的多个热切加载
