Question

我有2个猫鼬模特/模式（产品和商人）。在产品上执行.find（）时，它会按预期返回所有产品，但是当它为Merchants执行时，它会返回所有内容（商家和产品数据），而它应该根据定义的架构返回商家。我的mongoDB服务器上有一个集合，其中包含我的所有商家和产品。

知道我缺少什么吗？

由于

商家模式

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var MerchantShema = new Schema({
  merchants: [{
    merchant_id: Number,
    price_current: Number,
    price_rrp: Number,
    aff_link: String,
    merchant_product_id: Number,
    aw_image_url: String,
    cost_scoop: String,
    created_at: Date,
    updated_at: Date
  }]
});

module.exports = mongoose.model('Merchants', MerchantShema, 'products');

产品型号

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var ProductSchema = new Schema({
  ean: Number,
  aw_product_id: Number,
  product_name: String,
  product_brand: String,
  product_description: String,
  img_sml: String,
  img_lrg: String,
  cat: String,
  sub_cat: String,
  weight: String,
  rating: String,
  created_at: Date,
  updated_at: Date,
  merchants: [{
    merchant_id: Number,
    price_current: Number,
    price_rrp: Number,
    aff_link: String,
    merchant_product_id: Number,
    aw_image_url: String,
    cost_scoop: String,
    created_at: Date,
    updated_at: Date
  }],
  nutrition: [{
    calories: Number,
    protein: Number,
    fat: Number,
    sat_fat: Number,
    carbs: Number,
    sugar: Number,
    salt: Number,
    calories: Number
  }],
  ingredients: String,
  flavours: String,
  is_active: Boolean
});

module.exports = mongoose.model('Products', ProductSchema, 'products');

我的路线

  app.get('/api/products', function(req, res) {
    Products.find(function(err, products){
        if (err) return console.error(err);
        return res.send(products);
    })
    .where('is_active').equals('true')
  });

  app.get('/api/merchants', function(req, res){
    Merchants.find(function(err, merchants){
      if (err) return console.error(err);
      return res.send(merchants);
    });
  });

Answer 1

查看商家模型定义。您在导出中呼叫产品：

module.exports = mongoose.model('Merchants', MerchantShema, 'products');

这应该是

module.exports = mongoose.model('Merchants', MerchantShema, 'merchants');

我注意到的另一件事是你有两个叫做“卡路里”的钥匙。

我运行了代码，它现在正确地带回了商家。但是，当您调用产品时，它会将商家作为该架构的一部分返回，因为商家已包含在产品中。另一种方法是使用嵌套模式。您可以阅读其他帖子中的内容：Mongoose subdocuments vs nested schema

希望有所帮助。

模型没有返回预期的内容
