i have a function 'filter' which is suppose to filter data from firestore based on name. I am able to get the whole data from firestore

Issue

My challenge is in the collection reference in my function. My collection is like 'users/user.id/mat'is this the correct way of doing this. Please help

filter(){
    this.mat = this.afs.collection('users/user.id/mat', ref => ref.where('name','==','testUID')).valueChanges()
    console.log(this.mat);
    return this.mat
   }

Solution

You have to subscribe to the valueChanges():

this.afs.collection('users/user.id/mat', ref => ref.where('name','==','testUID')).valueChanges().subscribe(response =>{
    if(response){
       console.log(response);
    }
});
