jobskill_ref.delete is not a function

Call the doc() method and pass references of database, collection name and ID of a document that we want to delete. Assign it to a constant called docRef. Let's make a deleteDoc() query to perform deleting a document from a cities collection in Cloud Firestore.
Which of the following method is used to delete a field from a particular document in firebase? Deleting Fields For deleting a specific field from a document, use the FieldValue. delete() method when we update a document.
You can only delete a document once you have a DocumentReference to it. To get that you must first execute the query, then loop over the QuerySnapshot and finally delete each DocumentSnapshot based on its ref.
var jobskill_query = db.collection('job_skills').where('job_id','==',post.job_id); jobskill_query.get().then(function(querySnapshot) { querySnapshot.forEach(function(doc) { doc.ref.delete(); }); }); I use batched writes for this. For example:
var jobskill_ref = db.collection('job_skills').where('job_id','==',post.job_id); let batch = firestore.batch(); jobskill_ref .get() .then(snapshot => { snapshot.docs.forEach(doc => { batch.delete(doc.ref); }); return batch.commit(); }) ES6 async/await:
const jobskills = await store .collection('job_skills') .where('job_id', '==', post.job_id) .get(); const batch = store.batch(); jobskills.forEach(doc => { batch.delete(doc.ref); }); await batch.commit(); If you love us?
