Alias field in Realm function

MongoDB Atlas Atlas Triggers & Functions

Sure. Its a webhook in Realm.
I’m not actually using a Realm “Function” but a Realm 3rdParty HTTP webhook.

Here is the code:

/*

  • getStudents webhook function request handler.
  • Get a list of students for the given arguments
  • arguments: accountId
  • console execution ex: exports({query: {accountId:‘5e89f69d1c9d440000929b9a’ }}, new HTTPResponse())
    */

exports = async function getStudents(payload, response) {
const {accountId } = payload.query;
const db = context.services.get(“mongodb-atlas”).db(“usersDB”);
const students = db.collection(“students”);
console.log(getStudents accountId:${accountId});

const query = { accountId:accountId };
//const projection = { "studentId": "$_id", };
const projection = { "_id": 1, "studentId":"$_id", "firstName":"$firstName","lastName":"$lastName",  "accountId":"$accountId"};

console.log ('getting students query:', JSON.stringify(query));

response.setHeader("Content-Type","application/json");

//await students.find(query).toArray()
await students.find(query, projection).toArray()
.then(result => {
    if(result) {
      response.setStatusCode(200);
      //response.setBody(`{"students":${result}`);
      response.setBody(`{"students":${JSON.stringify(result)}}`);
    }
    else {
      console.log("students not found:",JSON.stringify(result));
      response.setStatusCode(404);
      response.setBody(`{message:"No students not found for given criteria"}`);
    }
}).catch(err => {
  console.log("error getting students:",err);
  response.setStatusCode(500);
  response.setBody(`{error:${err}}`);
})

}
