I use lightning data service method SaveRecord to create a record of type BoatReview__c. The boatReview__c object has following fields:
I only populate Name and comment__C field using a form on my component. I also use a helper function to populate the value of Boat__c with parent object Id. I am not sure why there is boat__c and boat__r(two variables). I show you below when I populate the boat__c value only.Before executing the LDS saveRecord method , below is how my JSON looks like:
{
"apiName": "BoatReview__c",
"childRelationships": {},
"fields": {
"Boat__c": "a021I000003VMuVQAW",
"Boat__r": {
"displayValue": null,
"value": null
},
"CreatedBy": {
"displayValue": null,
"value": null
},
"LastModifiedBy": {
"displayValue": null,
"value": null
},
"Name": {
"displayValue": null,
"value": null
},
"Id": {
"value": null
},
"Comment__c": {
"value": null
}
},
"id": null,
"recordTypeInfo": null,
"Name": "test",
"Comment__c": "<p>test</p>"
}
I also try populating boat__c and boat__r. Which gives me below JSON. I have an attr in my component which has a value for boat__c object that I using to populate.
{
"apiName": "BoatReview__c",
"childRelationships": {},
"fields": {
"Boat__c": "a021I000003VMuVQAW",
"Boat__r": {
"BoatType__r": {
"Id": "a011I00000Amwb2QAB",
"Name": "Ski Boat"
},
"Contact__r": {
"Email": "rachel@trailheadboats.com",
"HomePhone": null,
"Id": "0031I000008E0itQAC",
"Name": "Rachel King"
},
"Description__c": null,
"Id": "a021I000003VMuVQAW",
"Length__c": 15,
"Name": "The Old Man and the Sea",
"Picture__c": "/resource/Sailboats/skiboat2.png",
"Price__c": 55000,
"SystemModstamp": "2017-12-07T02:38:27.000Z"
},
"CreatedBy": {
"displayValue": null,
"value": null
},
"LastModifiedBy": {
"displayValue": null,
"value": null
},
"Name": {
"displayValue": null,
"value": null
},
"Id": {
"value": null
},
"Comment__c": {
"value": null
}
},
"id": null,
"recordTypeInfo": null,
"Name": "st",
"Comment__c": "<p>test</p>"
}
However the saveResult of recordData.saveRecord($A.getCallback(function(saveResult) returns an Error. I try to investigate the error but it prints undefined. Any idea what is wrong?
for (var i = 0; i < saveResult.error.length; i++) {
errMsg += saveResult.error[i].message + "\n";
console.log('errMsg is *** ' + errMsg);
}
component.set("v.recordError", errMsg);
errMsg prints undefined.

var errMsg = "";
// saveResult.error is an array of errors,
// so collect all errors into one message
for (var i = 0; i < saveResult.error.length; i++) {
errMsg += saveResult.error[i].message + "\n";
console.log('errMsg is *** ' + errMsg);

component.set("v.recordError", errMsg);

toastEvent.setParams({

Helper:

console.log('onInit Helper funciton in ' + event.changeType);
console.log('component value is ' + JSON.stringify(component.get("v.boat")));
console.log('component value is ' + JSON.stringify(component.get("v.boatReview")));
component.find("service").getNewRecord(
"BoatReview__c", // sObject type (objectApiName)
null, // recordTypeId
false, // skip cache?
$A.getCallback(function() {
var rec = component.get("v.record");
var error = component.get("v.recordError");
if(error || (rec === null)) {
console.log("Error initializing record template: " + error);
return;
}
console.log("Record template initialized: " + JSON.stringify(rec));
rec.fields.Boat__r = component.get("v.boat");
rec.fields.Boat__c = component.get("v.boat").Id;
component.set("v.boatReview",rec);
console.log("BoatReview template ----> : " + JSON.stringify(component.get("v.boatReview")));
})
);
}
})
Boat__cis the primary key, and stores the id value of the lookup record.Boat__ris the relationship name, and stores the data of the related object when its retrieved via soql or another method. Trying to accessBoat__c.Namewould fail, butBoat__r.Namewould be successful.isSuccessor an equivalent before trying to access the array of errors)
