Angular 6 Firebase each time upload should add new value (now its only changing the same)
I have my upload function which uploads some values to firebase real time database :
saveTeam(){
this.db.object(`projects/${this.auth.userId}/teams/${this.team.name}`).set(this.team)
}
It creates in DB like this :
Projects/UserID/Teams/TeamNamen {
name: string; empName: string;
}
I want that I could add as many empNames as I want. How to achieve it ?

It depends a bit on what the meaning of the collection of empNames.
If you just want a list of the names, in the order in which you added them, you can use Firebase's push() function:
var teamRef = firebase.database().ref(`projects/${this.auth.userId}/teams/${this.team.name}`);
teamRef.child('empNames').push(newEmpName);
This creates a list like this:
"empNames": {
"-LKJDSF2398y2uhd": "Name 1",
"-LMdswein2rasASD": "Name 2",
"-LO123dsi2r3AD1s": "Name 3"
}
However if each empName value can be in the team only once, it's really a mathematical set, instead of a list. In that case you'd use a different structure in Firebase:
"empNames": {
"Name 1": true,
"Name 2": true,
"Name 3": true
}
In this collection each name is guaranteed to be unique. You create it with:
teamRef.child("empNames").child(newEmpName).set(true);

However if each empName value can be in the team only once, it's really a mathematical set, instead of a list. In that case you'd use a different structure in Firebase:
"empNames": {
"Name 1": true,
"Name 2": true,
"Name 3": true
}
In this collection each name is guaranteed to be unique. You create it with:
teamRef.child("empNames").child(newEmpName).set(true);
