Help Navigating Soql query in visualforce

Hi, I created a parent to child query that will relate son to father but I can not get the Name, Age__c from the Father__r. I am trying to return results in my visualforce page using outputfield. Could any one help.

 

 

  


        son = [select Id, First_Name__c, Last_Name__c, Age__c, 
               (Select Id, Name, Age__c From Fathers__r) 
               from Son__c
               where name=:ApexPages.currentPage().getParameters().get('id')];


 

 

 

  <apex:outputField value="{}"/>  

  <apex:outputField value="{}"/>

 <apex:smileysurprised:utputField value="{!son.Fathers__r.Name}"/> 

 

Assuming that the relationship name is correct!

When I try to put that in I get this error:

 

Error: Could not resolve the entity from <apex:outputField> value binding '{!Son__c.Fathers__r.Name}'. outputField can only be used with SObject fields.

Hey

 

Your current query is child to parent btw i.e. sons are children of parents, and your 'main' query object is son. Therefore your query should be:

 

 

son = [select Id, First_Name__c, Last_Name__c, Age__c, 
               Fathers__r.Id, Fathers__r.Name, Fathers__r.Age__c
               from Son__c
               where name=:ApexPages.currentPage().getParameters().get('id')];



Your page could then output the father's details like so:

 

<apex:outputText value="{!son.fathers__r.name} />
