Retrieve data from firebase database using ionic3 angularjs
-1
I am trying to Retrieve data from firebase database, but the problem is when I use code onAuthStateChanged to allow user to read or write data and I got the error:
property 'map' does not exist on type '{}'
getpost (){
this.fire.auth.onAuthStateChanged(function(user) {
if (user) {
this.userId = user.uid
console.log(user)
this.itemsRef = this.db.list(`report/`);
this.items = this.itemsRef.snapshotChanges().pipe(
map(changes =>
changes.map(c => ({ key: c.payload.key, ...c.payload.val() }))
)
);
} else {
// No user is signed in.
}
});
}
ionViewWillLoad(){
this.getpost()
}
rules database
{
"rules": {
"users": {
"$uid": {
".write": "auth.uid === $uid"
}
}
}
}
