[英]Mongoose model schema referencing not working - Ecommerce model
I am creating multi vendor ecommerce platform, with the following schema.我正在创建具有以下架构的多供应商电子商务平台。
var user = new Schema(
{
uid: { type: String, index: true, unique: true },
firstName: { type: String, required: true, default: null },
lastName: { type: String, default: null, default: null },
userEmail: { type: String, unique: true, required: true, lowercase: true, },
userProfileImg: { type: String, required: true, default: null },
userDesignation: { type: String, default: null },
userMobile: { type: Number, required: true, default: null },
products: { type: Schema.Types.ObjectId, ref: 'Product' },
}
);
var product = new Schema(
{
sku: { type: String, required: true, unique: true },
title: { type: String, required: true },
category: { type: Array, default: [] },
images: { type: Array, default: [], },
groups: { type: Array, default: [], },
price: { type: Number, default: null, },
unit: { type: String, default: null, },
quantity: { type: Number, default: null, },
description: { type: String, default: null, },
},
);
var AllUser = mongoose.model('User', user, 'AllUsers');
var Allproducts = mongoose.model('Product', product, 'AllProducts');
how can i save multiple products while referring to multiple users?如何在引用多个用户的同时保存多个产品? Later i want to populate products based on the users.
后来我想根据用户填充产品。
Your problem is in referencing the collection.您的问题在于引用集合。 In here when you compile your models
在这里编译模型时
var AllUser = mongoose.model('User', user, 'AllUsers');
var Allproducts = mongoose.model('Product', product, 'AllProducts');
you use Product and for database collection you use AllProducts.您使用 Product,而对于数据库收集,您使用 AllProducts。 That's the problem so...try doing it like this
这就是问题所以...尝试这样做
var Users = mongoose.model('Users', user, 'Users');
var Products = mongoose.model('Products', product, 'Products');
Give it a proper naming convention.给它一个适当的命名约定。
Also there is s typo here in this code.. here I have fixed it这段代码中也有错别字..在这里我已经修复了它
var product = new Schema(
{
sku: { type: String, required: true, unique: true },
title: { type: String, required: true },
category: { type: Array, default: [] },
images: { type: Array, default: [] },
groups: { type: Array, default: [] },
price: { type: Number, default: null },
unit: { type: String, default: null },
quantity: { type: Number, default: null },
description: { type: String, default: null}
}
);
also in your user schema也在您的用户架构中
var user = new Schema(
{
uid: { type: String, index: true, unique: true },
firstName: { type: String, required: true, default: null },
lastName: { type: String, default: null, default: null },
userEmail: { type: String, unique: true, required: true, lowercase: true,
},
userProfileImg: { type: String, required: true, default: null },
userDesignation: { type: String, default: null },
userMobile: { type: Number, required: true, default: null },
products: [{ type: Schema.Types.ObjectId, ref: 'Product' }]
}
);
make products as an array type so that you can store multiple product ids将产品设为数组类型,以便您可以存储多个产品 ID
