Exploring the world of Vue.js object mapping

I currently have the following object:

data: () => ({
            customer: {
                item: {
                    name: undefined
                }}
})

This object is being used in the template as follows:

<v-number
separator="."
decimal="2"
group-by="3"
error-text="system.global.customer"
v-model="customer.item.name"
></v-number>

However, I am encountering an error:

[Vue warn]: Error in render: "TypeError: Cannot read property 'name' of undefined"

What could I be doing wrong?

On the other hand, this section of code works correctly:

data: () => ({
            customer: {
                item: undefined}
})
v-model="customer.item"

Answer №1

Check out this code snippet

data() {
  return {
    user: {
      product: {
        title: "Sample Product"
      }
    }
  }
},

Can you elaborate on where the v-model directive is being used and explain the purpose of your template?
