I have a puted property that populates an array, however i'm working with this array afterwards (pushing from & to it) and i want once the array is empty, to remain empty (said puted property not to populate it again).How can i do that? I'm using a puted property because i'm fetching data from the Vuex store via getter. Here's the property in question:
populateAvailableMachines() {
Object.values(this.userData).forEach(user => {
if (this.$auth.user().id == user.id) {
if (this.availableMachines.length == 0) {
Object.keys(user.machine).forEach(key => {
this.availableMachines.push(user.machine[key].machine_name);
});
}
}
});
},
And here's the method that pushes/splices:
addMachineTab(item) {
let index = this.availableMachines.indexOf(item);
this.selectedMachines.push(this.availableMachines.splice(index, 1));
},
What i want to achieve is, once all the values from the available machines array are moved to the selected machines array, not to re-run the puted property that populates the empty available machines array.

Reset to default 5It' not remended to make puted
properties produce any side effects like data
mutating.
It would better to move populateAvailableMachines
function to methods and call it only once (e.g. on mounted).
Use watcher instead.
watch: {
userData: {
handler: function (val, oldVal) {
if(this.availableMachines.length > 0){
// put your populate logic here
}
},
deep: true
}
},
Besides, you may need to initialize your data(userData
and availableMachines
) in created
or mounted
hook.
