Question

我需要多次在路径：“ suppliesData.supplies”，路径“ altRecipes.altRecipe”和路径“ employee”处使用相同的路径“ recipes”填充模型。

  Table.updateTable(id, order, {}, (err, order) => {
  if (err) {
    throw err;
  }
  Order.populate(
    order,
    {
      path: "recipes",
      populate: {
        path: "suppliesData.supplies",
      }
    },
    (err, order) => {
      if (err) {
        throw err;
      }
       Order.populate(
    order,
    {
      path: "employee",
      }
    },
    (err, order) => {
      if (err) {
        throw err;
      }
     Order.populate(
    order,
    {
      path: "recipes",
      populate: {
        path: "altRecipes.altRecipe"
      }
    },
    (err, order) => {
      if (err) {
        throw err;
      }
      res.json(order);
    }
  );
});
    }
  );
});
    }
  );
});

}

在documentation中明确指出：

如果您使用相同的路径多次调用populate（），则只有最后一个才会生效。

//下面的第二个populate()调用将覆盖第一个，因为它们 //都填充“粉丝”。

Story.
  find().
  populate({ path: 'fans', select: 'name' }).
  populate({ path: 'fans', select: 'email' });
// The above is equivalent to:
Story.find().populate({ path: 'fans', select: 'email' });

在我的情况下，路径“ suppliesData.supplies”和“ altRecipes.altRecipe”都填充了配方，因此，我可以理解发生了什么，但是，它们没有解释如何解决该情况，因此我找不到任何示例关于如何做。

非常感谢任何帮助。

编辑：很抱歉，看错了杰森，这就是那个

更新：我做了显示的更改，现在它填充了雇员和路径：“ altRecipes.altRecipe”，但没有填充路径：“ suppliesData.supplies”（或者是，它确实填充了“ suppliesData.supplies”，但是被覆盖由“ altRecipes.altRecipe”），因此它正按文档所述运作。.问题仍然相同，如何处理？

猫鼬使用相同的路径多次填充
