I want to store the documentId created in collection as the field/property as docid in the same document. I am using cloud firestore.
It is showing error "ReferenceError: doc is not defined" whenever I try and store the doc.id
db.collection("Colleges").doc(user.uid).collection('Internships').doc().set({
CompanyName :this.I_company,
InternshipTitle : this.I_title,
duration: this.duration,
amount:this.I_amount,
week:this.week,
docid: doc.id
})

Indeed, a call to the doc()
method of a CollectionReference
without any path will return a DocumentReference
with "an automatically-generated unique ID".
But you have to do as follows: first get the new DocumentReference
, then use the set()
method on this DocumentReference
.
var docRef = db.collection("Colleges").doc(user.uid).collection('Internships').doc();
docRef.set({
CompanyName :this.I_company,
InternshipTitle : this.I_title,
duration: this.duration,
amount:this.I_amount,
week:this.week,
docid: docRef.id
})
However, you may double check if you really need to write the docRef.id
in a specific field of the document, because in any case you can get it later with the id
property.
