Good morning, I'm new to the Ionic / AngularFire branch and I'm having a hard time recovering the value of a child from within my Database. The idea is to take this value and store it in a variable so I can make some comparisons within my code.
This is my Database ]
Thisismyattempttorecoverthevalueofchild"typeuser"
try this:
this.db.object('clientes/'+this.id)
.valueChanges()
.subscribe(statususer => {
var statusCliente = statususer.status;
});
When I manually assign the userId within the path
this.afData.object('Usuários/pqMaisUMrWUrk8v8TZmvzQjd1H82/Dados Pessoais/typeuser')
Full function:
constructor(
public navCtrl: NavController,
private afData: AngularFireDatabase,
private afAuth: AngularFireAuth) {
this.afAuth.authState.subscribe(user => {
if(user) this.userId = user.uid})
this.afData.object('Usuários/pqMaisUMrWUrk8v8TZmvzQjd1H82/Dados Pessoais/typeuser')
.valueChanges()
.subscribe(dataclient=>{
console.log(dataclient)
this.typeUser=dataclient;
});
}
I get the value of the child "typeuser" and store it in a variable.
ButwhenIputthevariableuserId(asdescribedbelow)Iget"null" as a return.
this.afData.object('Usuários/'+this.userId+'/Dados Pessoais/typeuser')
Full function:
constructor(
public navCtrl: NavController,
private afData: AngularFireDatabase,
private afAuth: AngularFireAuth) {
this.afAuth.authState.subscribe(user => {
if(user) this.userId = user.uid})
this.afData.object('Usuários/'+this.userId+'/Dados Pessoais/typeuser')
.valueChanges()
.subscribe(dataclient=>{
console.log(dataclient)
this.typeUser=dataclient;
});
}
After trying several times performing checks to verify the values of the variables in the HTML page I discovered that the values were there in the variables but were not being passed to the other functions. I was able to solve by leaving only the getIdUser function inside the constructor and inside it calling the others and it worked!
constructor(
public navCtrl: NavController,
private afData: AngularFireDatabase,
private afAuth: AngularFireAuth) {
this.afAuth.authState.subscribe(user => {
if(user) this.userId = user.uid
this.searchTypeUser()});
}
searchTypeUser(){
this.afData.object('Usuários/'+this.userId+'/Dados Pessoais/typeuser')
.valueChanges()
.subscribe(dataclient=>{
console.log(dataclient)
this.typeUser=dataclient
this.redirect()});
}
redirect(){
if (this.typeUser=='client') {
this.navCtrl.push(ClientPage)
}if(this.typeUser=='coordinator'){
this.navCtrl.push(CoordinatorPage)
}if(this.typeUser=='promoter'){
this.navCtrl.push(PromoterPage)
}if(this.typeUser=='admin'){
this.navCtrl.push(ConsolePage)
}
}
