error while fetching notification data from firebase
0
Hello I'm new in react native. I'm working on push notifications through firebase. I have implemented the functionality of notification. But the problem is I'm not able to fetch the data from the firebase real time database. Here is my code to fetch the data from firebase. I just want to fetch the events which is shown in image.
fetchFriendsList=(eventId)=>{
let allEventsList = [...this.state.allEventsList];
firebase.database().ref('/events').child(eventId).once('value').then((snapshot) => {
let data = snapshot.val();
let items = Object.values(data);
allEventsList.push(items);
this.setState({allEventsList : allEventsList});
ToastAndroid.show("kk>"+allEventsList.length , ToastAndroid.SHORT);
}).then((data)=>{
}).catch((error)=>{
//error callback
console.log('error ' , error)
})
}
//get event id from user events
deleteOldEvents=()=>{
let eventsList = [...this.state.userEventsList];
for(var i=0;i<eventsList.length;i++){
this.deleteFromFireBase(eventsList[i].eventId)
}
}
//app users remove that not in contacts
deleteFromFireBase=(eventId)=>{
let timeRemaining = 1;
firebase.database().ref('/events').child(eventId).once('value').then((snapshot) => {
let data = snapshot.val();
let STime = data.sTime; // start time
let eventDate = data.eventDate;
timeRemaining=this.remainingTimeInMin(STime,eventDate);
}).then((data)=>{
//remove from events
if(timeRemaining < 0){
this.setState({removeEventsList:});
firebase.database().ref('/events').child(eventId).child('friends').once('value').then((snapshot) => {
let data = snapshot.val();
let items = Object.values(data);
this.setState({removeEventsList:items});
}).then((data)=>{
//remove event data from users node
let removeEventsList = [...this.state.removeEventsList];
for(var i=0;i<removeEventsList.length;i++){
let getPhone= removeEventsList[i].phone
firebase.database().ref('/users').child(getPhone).child('/events').child(eventId).remove();
}
//remove whole event from event node
firebase.database().ref('/events').child(eventId).remove();
}).catch((error)=>{
//error callback
console.log('error ' , error)
})
}
}).catch((error)=>{
//error callback
console.log('error ' , error)
})
}
