I'm having a problem in pushing these data to an nested object.
Here is what I put on postman as JSON format:
"productId":"621256596fc0c0ef66bc99ca",
"quantity":"10"
here is my code on my controller
module.exports.createOrder = async (data) => {
let product = data.productId;
let oQuantity = data.quantity
let totAmount = data.totalAmount
return User.findById(product).then(user =>{
user.userOrders.products.push({productId:product})
user.userOrders.products.push({quantity:oQuantity})
if (user) {
return user.save().then((savedOrder,err)=>{
if (savedOrder) {
return user
} else {
return 'Failed to create order. Please try again'
}
})
} else {
return "try again"
}
})
}
my schema is:
userOrders:[
{
products:[
{
productName:{
type: String,
required: [true, "UserId is required"]
},
quantity:{
type: Number,
required: [true, "Quantity is required"]
}
}
],
totalAmount:{
type: Number,
required: [true, "Quantity is required"]
},
PurchasedOn:{
type: Number,
default: new Date()
}
}
]
})
i got these error on my CLI
user.userOrders.products.push({productId:product})
^
TypeError: Cannot read properties of null (reading 'userOrders')
Currently i wish to just put these data from postman to the nested object but i think im not using the push use-case well. Any tips?
user is not found and contains null. User.findById(product) returns an empty result. The ID product can't be found in User. First, check if the user was found, then, push the products:
module.exports.createOrder = async (data) => {
let product = data.productId;
let oQuantity = data.quantity
let totAmount = data.totalAmount
return User.findById(product).then(user => {
if (!user) {
return "try again";
}
user.userOrders.products.push({productId:product})
user.userOrders.products.push({quantity:oQuantity})
return user.save().then((savedOrder, err) => {
if (savedOrder) {
return user;
} else {
return 'Failed to create order. Please try again';
}
});
});
};
