I am encountering a perplexing issue with my angular app that is connected to Firestore. Despite following the documentation closely, when I query for documents in a collection based on a specific condition, the array returned contains every single document in the collection.
The code snippet below showcases the call to the collection within the component:
this.FirebaseService.getDocsByParam( 'versions', 'projectId', this.projectData.uid )
.then((snapshot) => {
var tempArray = [];
var docData;
snapshot.forEach((doc) => {
docData=doc.data();
docData.uid=doc.id;
tempArray.push(docData);
});
this.versionList = tempArray;
this.versionData = this.versionList[this.versionList.length-1];
this.initializeAll();
})
.catch((err) => {
console.log('Error getting documents', err);
});
This is the Firebase service responsible for making the call:
getDocsByParam( collection, getParam:string, paramValue:string ) {
var docRef = this.afs.collection(collection, ref => ref.where(getParam, '==', paramValue));
return docRef.ref.get();
}
Furthermore, the screenshot below illustrates the versions collection, displaying one of the retrieved documents that doesn't even contain the required field.
