My issue is that in my subscribeEquippedItems(): Observable method after
mapping to an array of type Item for some reason the output is an empty
array instead of a array.
So just to test that I was getting objects back I did the following in the
constructor of my class:
this.subscribeTest()
.subscribe(items => { console.log('TEST: '); console.log(items); });
Which calls the following method in that class:
subscribeTest(): Observable<any> {
return this.af.database.list('users/uniqueIdIsHere/equippedItems');}
This output an array of 3 objects in the console. They are like this:
[Object, Object, Object]
When opened they look like:
Array[3]
0: Object
title: "testtitle"
active: false
1: Object
2: Object
In my class that will display the items I have:
loadItems() {
this.itemsService.subscribeEquippedItems().subscribe(x => {
// this.equippedItems = x;
console.log(x);
});}
Which calls the itemsService:
subscribeEquippedItems(): Observable<Item[]> {
let yoyo = Observable.of(new Array<Item>());
this.session.uid.subscribe(x => {
console.log('users/' + x + '/equippedItems'); // this is correct vaue
yoyo = this.af.database.list('users/' + x + '/equippedItems')
.map(Item.fromJsonList).do(z => {
console.log('trying to map here');
console.log(z);
}).do(s => {
console.log('STARTSTARTSTARTSTART: ');
console.log(s); // this shows as an empty array in console
console.log(' : FINISHFINISHFINISH');
});
});
return yoyo;}
Here is the item class:
public title: string;public active: boolean;
static fromJsonList(array: any): Item[] {
console.log('tester');
console.log(array); // blank array shows on console
return array.map(Item.fromJson);}
static fromJson({title, active}: any): Item {
return new AvatarItem(title,active);}
constructor(title: string, active: boolean){
this.title = title;
this.active = active;}
