Render data from an API into a Vue Template

I am successfully fetching api in vue but how to properly render it? "undefined id of null" is what I get in console error

this is the axios call I made

  axios.getOrder(id).then(response => {
    this.cart_content = response.data
    console.log(this.cart_content)
  })

this is how I'm trying to render in in vue

       <div v-if="cart_content">
          <ul v-for="i in cart_content" :key="i.id">
            <li>
              <p>{{i.name}}</p>
              <p>{{i.items.quantity}}</p>
              <p>{{i.items.unit_price}}</p>
            </li>
          </ul>
        </div>

the API is available when I console.log, it looks something like this.

id:'',
data:array[1]

the "data array" is where the details I need, can anyone tell me how to get these data.

Because your data is collected in an asynchronous way, it's not initially available to your component, hence it errors out. You'll need to fetch the data on a component lifecycle method, something like this:

import axios from 'axios';

export default {
  data() {
    return {
      cart_content: [],
      id: ''
    }
  },
  created() {
    this.getOrder(this.id)
  },
  methods: {
    getOrder(id) {
      axios.getOrder(id)
        .then(response => {
          this.cart_content = response.data;
        });
    }
  }
}

methods: {
getsomething(){
var apicall = axios.get("https://jsonplaceholder.typicode.com/users");
apicall.then(resp => {
for(var x = 0; x < resp.data.length; x++){
for(var dataCount = 0; dataCount < resp.data.length; dataCount++)
{
if(resp.data[dataCount].id == resp.data[x].id)
{
this.cart_content = resp.data[x].id;
}
}
}
})
}
}
<template>
<div>
  <div v-if="cart_content">
          <ul v-for="i in cart_content" :key="i.id">
            <li>
              <p>{{i.name}}</p>
              <p>{{i.items.quantity}}</p>
              <p>{{i.items.unit_price}}</p>
            </li>
          </ul>
        </div>
</div>
</template>

Apparently my code is not wrong after all I just had to include the name of the array of object from the response to get what I wanted (cart_content.data) in v-for thanks for helping me out here guys I appreciate your time
