Hey guys, i’m having some problem querying my data with firebase.
I have the below structure
The user has some pets and i want to get a list of all pets the user has in the pets node.
I did the following approach:
for (let petUID in this.user.pets) {
this.af.database.object("/pets/" + petUID ).subscribe(data => {
this.ownPets.push(data);
});
}
At the end i get all the pets in my ownPets
variable.
But it just like awkward to me this approach.
If any data is updated in the pets node from a pet that is inside the ownPets
array, this pet is pushed again and i get the outdated and the new pet inside the ownPets
.
I tried another approach: use the query method and send an array of objects in the equalTo
but i get an error saying i can’t send an array of objects.
this.af.database.list('/pets', {
query: {
orderByChild: "name",
equalTo: ["pet1", "pet2"]
}
}).subscribe (data => {
console.log(data);
});
Anyone have a better approach i can use?
Thanks
