Javascript Loopback.io包含多个模型查询条件

对于单个模型查询，我们可以对查询中定义的条件应用条件操作，其中and/or运算符应用于一系列条件：

{ where: {<and|or>: [condition1, condition2, ...]}}

---

是否可以在上述条件1、条件2上应用和/或操作，即返回所有模型，使其与所包含模型范围内定义的条件相匹配。

我相信您可以按照以下代码示例执行此操作：

Post.find({
  include: {
    relation: 'owner', // include the owner object
    scope: { // further filter the owner object
      fields: ['username', 'email'], // only show two fields
      include: { // include orders for the owner
        relation: 'orders', 
        scope: {
          where: {orderId: 5} // only select order with id 5
        }
      }
    }
  }
}, function() { ... });

这是为包含过滤器记录的

Post.find({
  include: {
    relation: 'owner', // include the owner object
    scope: { // further filter the owner object
      fields: ['username', 'email'], // only show two fields
      include: { // include orders for the owner
        relation: 'orders', 
        scope: {
          where: {orderId: 5} // only select order with id 5
        }
      }
    }
  }
}, function() { ... });
