Filtering 'timestamp' data from Firebase
I am using AngularFire2 and trying to query a certain range of data based on TimeStamp.
The code I am using is as follows:
this.db.list('timeRecords/' + this.userID + '/' + this.teamRef, ref
=> ref.orderByChild('timeStamp')
.startAt("<starting_timestamp>")
.endAt("<ending_timestamp>"))
.valueChanges().subscribe(data => {
console.log(data)
})
The data returns an empty array !!
The data at the Firebase DB (on the specified node i:e 'timeRecords/' + this.userID + '/' + this.teamRef ) is shown in the public gist at the following URL:
https://gist.github.com/DevlprArup/3fe83e6e6082d5b1d419bc8a1831cef4
How do I get an Array containing the specified range ??

all in all it looks quite okay to me. Only thing i can see is that you put in "..." timestamp as starting / ending timestamp. Please make sure it is a number!

after checking your link with the data it kinda looks like you are querying the wrong way. could you try this:this.db.list('timeRecords/' + this.teamRef + '/' + this.userID?
