I'm writing my first Laravel Vue component and I have this error in console.
[Vue warn]: Computed property "options" was assigned to but it has no setter.
I just miss to update the options of the second select with the updated values I have in this.countries.
After the change this.countries get updated but the values of the options of the country_id select are not changing. I've tried adding computed but I get this error.
What am I doing wrong?
<template>
<div>
<div class="form-group continent_id">
<select name="continent_id" v-model="continent_selected" id="continent_id" class="selectpicker" data-live-search="false" title="Pick a continent" v-on:change="getAllCountries(continents)">
<option v-if="continents.length>0" v-for="continent in continents" v-bind:value="continent.id">
</option>
</select>
</div>
<div class="form-group country_id">
<select name="country_id" v-model="country_selected" id="country_id" class="selectpicker" data-live-search="true" title="Pick a country">
<option v-for="(country, index) in countries" v-bind:value="country.id" >
</option>
</select>
</div>
</div>
</template>
