I have this model files where I have a property that is response that inside has an array errorMessages and inside my Vue component I want to show errors one by one, not in array format.

Is there any way to do it?

 { "files": [ { "fileObject": true, "size": 9387, "name": "file_4444.pdf", "type": "application/pdf", "active": false, "error": true, "success": true, "postAction": "http://localhost:8000/api/v1/car/upload", "timeout": 0, "file": {}, "el": { "__vue__": null }, "response": { "uploadDone": 0, "uploadFail": 1, "errorMessages": [ "User not found", "Car not found", ] }, "progress": "100.00", "speed": 9591, "data": {}, "headers": {}, "id": "096vnj6rov9t", "xhr": {} } ] }

<template> <div class="example-drag"> <div class="upload"> <ul v-if="files.length"> <li v-for="(file, index) in files" :key="file.id"> <span>{{file.name}}</span> - <span v-if="file.error"> {{ file.response.errorMessages }} <md-icon>thumb_down</md-icon> </span> <span v-else-if="file.success">success <md-icon>thumb_up</md-icon> </span> <span v-else-if="file.active">active <md-icon>thumb_up</md-icon> </span> <span v-else> ... </span> </li> </ul> ... </template>

you need to iterate over the errorMessages array

<ul v-if="files.length"> <li v-for="(file, index) in files" :key="file.id"> <span>{{file.name}}</span> - <span v-if="file.error"> <ol> <li v-for="err in file.response.errorMessages> {{ err }} </li> </ol> </span> </li> </ul> 

Or use the .join method of the array ( ['hola', 'mundo'].join(", ") => 'hola, mundo')

<span v-if="file.error">{{ file.response.errorMessages.join(", ") }}</span>
