I am little confused how to push all objects from array to mongoose array field. Do I have to use loop?
I have created an inventory model where itemlist is an array of itemschema field
const itemlistSchema: mongoose.Schema = new Schema({
item: {
type: Schema.Types.ObjectId,
ref: "Item",
required: true,
},
quantity: {
type: Number,
required: true,
},
});
const inventorySchema: mongoose.Schema = new Schema(
{
code: {
type: String,
trim: true,
required: true,
unique: true,
},
user: {
type: Schema.Types.ObjectId,
ref: "User",
required: true,
},
shop: {
type: Schema.Types.ObjectId,
ref: "Shop",
required: true,
unique: true,
},
itemlist: [itemlistSchema],
},
{ timestamps: true }
);
module.exports = retailMongoose.model(
"Inventory",
inventorySchema,
"Inventory"
);
If I get an array from frontend or as input how can I update this inventory with items.
Suppose I get this array from frontend:
shop_id = "uniqueShopId"
items = [
{
item:"itemId",
quantity:20
},
{
item:"another itemID",
quantity:11
}
]
How can I push this to my inventory model. Every shop will have single inventory , so I can find inventory by shop_id.
Can any one help please? Thank you ❤️
I have created this solution which works for me.
//add items to inventory.itemslist
let itemsList = inventory.itemlist;
// console.log("Db itemsList ==>", itemsList);
//check if item already exists in inventory
for (let i = 0; i < items.length; i++) {
const item = items[i];
// find item in inventory
var itemInInventory = itemsList.findIndex(
(anitemInInventory: any) =>
// console.log(anitemInInventory.item_id.toHexString(), item.item_id)
anitemInInventory.item_id.toHexString() === item.item_id
);
// console.log("itemInInventory ==>", itemInInventory);
}
console.log("Existing Item ==>", itemInInventory);
if (itemInInventory > -1) {
//send error if item already exists
return res.throw_4906_ITEM_ALREADY_EXISTS(
"Item already exists inside inventory. Cannot add again ,you can update it"
);
}
items.forEach((item: any) => {
if (!item.item_id || !item.quantity) {
return res.throw_5005_INCOMPLETE_REQUIRED_FIELDS(
"Adding items invalid config"
);
}
itemsList.push({
item_id: item.item_id,
quantity: parseInt(item.quantity),
});
});
inventory.itemlist = itemsList;
await inventory.save();
return res.throw_2101_INVENTORY_UPDATE_SUCCESS("Items added to inventory", {
inventory,
});
