How to "separate" v-model from each other?

Question

Vue.js

There is a list of products that is pulled from the database. When adding this product to the general list, an input field appears for each product so that a person can enter a quantity and the price is calculated according to this quantity. But the problem is that the v-model is the same for everyone and, therefore, the field is automatically filled in the same way for everyone. How to avoid it? It is necessary that each input field be independent of the others.
Here is the code:

tr(v-for="item in cartItems")
                td
                    img(:src="item.img" class="imgs")
                td
                    span {{item.title}}
                td
                    input(v-model="value")
                td
                td
                    span {{item.price}}
                td &#8381
                td
                    span {{sumValue}}
                td 
                    span(@click="removeToCart(item)" style="cursor: pointer") &#x2716

Answer 1

You use v-for
You can get index in addition to item
And now you can declare a variable of type an array of objects

...
data: {
  items: []
}
...

And correspondingly

...
input(v-model="items[index].name")
...

It's like one of the solutions.
