Retrieve the field values of record in Lightning Component

Question

I am using the Lightning Data service in my Lightning Component to update a case record, before I do update the record I need to check on the field value and update accordingly. Below is my component

<aura:component implements="flexipage:availableForRecordHome,force:hasRecordId" access="global"  >
<aura:attribute name="loaded" type="Boolean" default="false" />
<lightning:spinner variant="brand" alternativeText="Loading..." class="{!(v.loaded? 'slds-show': 'slds-hide')}" />
 <lightning:recordEditForm aura:id="form" 
        objectApiName="Case" 
        recordId="{!v.recordId}"
        onsubmit="{!c.handleSubmit}"
        onerror="{!c.handleError}"
        onsuccess="{!c.handleSuccess}">
        <lightning:inputField aura:id="statusInput" fieldName="Status" class="slds-hide" />
        <lightning:button variant="brand" type="submit" label="Transfer" />
 </lightning:recordEditForm>    
</aura:component>

and the controller is like

  {
    handleSubmit: function(component, event, helper) {
    component.set('v.loaded',true);
    event.preventDefault();     
    
    var fields = event.getParam('fields');
    var country = fields.Account_Country__c;
    if( country == 'XYZ')
    {
        fields.OwnerId = 'XXXXXXXXXX'; 
    }
    else
    {
        fields.OwnerId = 'YYYYYYYYYYY'; 
    }
    console.log(JSON.stringify(fields)); 
    component.find('form').submit(fields); 
    $A.get("e.force:refreshView").fire();        
}, 

Here the country field is always undefined in the controller I tried even changing the to like below

   var country = component.get("v.recordId").Account_Country__c;

Even this is not returning the field value associated with the case record.How can I reterieve the field value so I can use them in the controller.

Answer 1

Its because you are missing the lightning:inputField for Account_Country__c

<lightning:inputField aura:id="accountCountryInput" fieldName="Account_Country__c" class="slds-hide" />

And you can access it like

var fields = event.getParam('fields');
var country = fields.Account_Country__c;

Also, the below code will never work as it a recordId, not the record itself.

var country = component.get("v.recordId").Account_Country__c;
