how to access object values in lightning component

I want to render a table dynamically in lightning. I have a list of data of transaction (Custom object) and list of string which contains API name which data i want to render.
I have created a child component and wrapped it in nested aura iteration to display the data. But I am unable to access the value.

aura:iteration items="{!v.Transactions}" var="trans">
       <tr>
       <aura:iteration items="{!v.fieldNames}" var="field" indexVar="ind">
         <td><c:TransactionOutputField object="{!trans}" fieldName="{!field}"/></td>
       </aura:iteration>
       </tr>
     </aura:iteration>

child component
___________________

<aura:component>
  <aura:attribute name="object" type="Object" />
  <aura:attribute name="fieldName" type="String" />
  <aura:attribute name="fieldVal" type="String" access="private" />
  <aura:handler name="init" value="{!this}" action="{!c.myAction}"/>

  {!v.fieldVal}
</aura:component>

controller
__________

({
    myAction : function(component, event, helper) {

        var obj = component.get("{!v.object}");
        var field = component.get("{!v.fieldName}");

        console.log(JSON.stringify(obj));
        console.log(field);

        var value = obj.field;
        console.log(value);

        component.set("v.fieldVal", value);

    }
})

debug value in the obj :

{"Id":"a0l1q000000BYLQAA4","Name":"0002000332","akritiv__Amount__c":0,"akritiv__Balance__c":0,"akritiv__Source_System__c":"SAPG","akritiv__Batch_Number__c":"20181003124027"}

debug value in the field :

akritiv__source_system__c

}

I have a custom object named custom list view where all the details from the vf page will be stored . From there in want to fetch newly created list view and add it to the lightning component and display data.

Thanks,

workbench rest explorer is showing 200 ok status but in debug log in am getting 400 bad request error . and the same code is working sometimes

Here is my code,

@RestResource (urlMapping='/rateupdate/test/*')
global class SampleRESTService {
@HttpPost
global static void doPost(){


RestRequest req = RestContext.request;

Map<String, Object> body = new Map<String, Object>();
String cur = '';
Double rate = 0.00;
String id;
String jsonBody = req.requestBody.toString();

if (!String.isBlank(jsonBody)) {
body = (Map<String, Object>)JSON.deserializeUntyped(jsonBody);
if (body.containsKey('currency')) {
cur = (String)body.get('currency');
CurrencyType ct = [Select id,IsoCode,ConversionRate From CurrencyType where isActive=true And IsoCode=:cur];
system.debug('currencyType====='+ct);
id = ct.Id;
}

if (body.containsKey('rate')) {
rate = (Double)body.get('rate');
}


}

Http h = new Http();
HttpRequest req1 = new HttpRequest();
req1.setEndpoint(URL.getSalesforceBaseUrl().toExternalForm() + '/services/data/v28.0/sobjects/CurrencyType/'+id+'?_HttpMethod=PATCH');

Map<String,double> rateMap =new Map<String,double>();

rateMap.put('ConversionRate',rate);

String body1=JSON.serialize(rateMap);
system.debug('body==='+JSON.serialize(rateMap));

req1.setBody(body1);
req1.setHeader('Authorization', 'OAuth ' + UserInfo.getSessionId());
req1.setHeader('Content-Type', 'application/json');
req1.setMethod('POST');
HttpResponse res = h.send(req1);

system.debug('response====='+res);

}

}

Json i am posting from workbench:;

{
   "currency": "USD",
   "rate": 9.00

}
