Hi Rao

Rao

hey Tyler,

How are you and whats that you are trying to do

Tyler Zika

So it looks like I'm trying to create multiple records, each of which use a different object type, on a single visualforce page

Rao

If I get your question right you need to create a VF page where you can create a bunch of input fields and get input on both Parent and child object and save both at the same time correct?

Tyler Zika

Yup

Rao

so you have 2 object in master detail 1) Custom object A - master 2) Custom object B- child correct?

Tyler Zika

Check it out

there is a 3rd object

All 3 need to be created on a single page

Rao

gotcha

1) You need to understand what is a controller/ Standard controller/ Extension

Tyler Zika

I do sorta

I think an extension will work for my problem, correct?

Rao

it will but

do you need a standard controller is the question

Tyler Zika

all I need to do is create new records

User fills out the form, and hits save

Rao

Ok lets focus on that first

<apex:page sidebar="false" standardStylesheets="false" standardController="Custom_Object_A__c">
    <apex:form>

    <apex:pageBlock title="Create Two New Records">

        <apex:pageBlockSection>
            <apex:inputField value="{! Custom_Object_A__c.Name}"/>
        </apex:pageBlockSection>

        <apex:pageBlockSection>
            <apex:inputField value="{! Custom_Object_A__c.Custom_Object_B__r.Name}"/>
        </apex:pageBlockSection>

        <apex:pageBlockButtons>
            <apex:commandButton action="{! save }" value="Save" />

This is your problem : Custom_Object_A__c.Custom_Object_B__r.Name

your data model is Custom object A ( Parent) and Custom object B(child)

you can use . (dot) notation only when you are accessing parent fields from child

Tyler Zika

9:53 PM

Yeah I got that thanks

Rao

for the other way you need a SOQL query to get the relationship

since you are building this on a standard controller you need to have extension defined to query the child fields from the parent

Step1 :

in the above code define an extension

<apex:page sidebar="false" standardStylesheets="false" standardController="Custom_Object_A__c" extensions="sensible_named_controller">

sensible_named_controller: define a controller / apex class name and save your vf page

let me know when you do this and we can write the extension for this page

Tyler Zika

Okay so use the standard controller for the parent object?

Rao

Salesforce for the sake of convenience provides prebuilt methods like save/ insert/ delete etcc...

when you do not wnat to have your custom logic written out you can use a standard controller and save the record

when you have a custom save logic then you go and start controller / extension

To answer ur question : Yes use parent object as the standard controller

let me know if the page saved and prompted you to create a class

Tyler Zika

K i made the extension and included it in my class

Rao

10:08 PM

awesome can you post your extension

Tyler Zika

public class NewSurveyExtension {

}

Rao

just a min

how do you want your design to be

Step 1: save parent record

Step 2: save the child 1

Step 3: save the child 2

(or)

Get all the parent child1 child2 on the same page, take all the info process it in the controller

Tyler Zika

I'm not sure, the first one seems right

Also, I'm not sure if this affects the decision, I want to be able to dynamically create multiple childs on the page if the user hits a button

and preview the records on one page before saving them

Rao

hmm so there is one button and the user hits save, and the parent/ child1 / child 2 record needs to be saved correct

<apex:page sidebar="false" standardStylesheets="false" standardController="Custom_Object_A__c" extensions="NewSurveyExtension">
	<apex:form>

	<!-- Custom object A fields-->
	<apex:pageBlock title="Create Two New Records">

	<apex:pageBlockSection>
	<apex:inputField value="{! Custom_Object_A__c.Name}"/>
	</apex:pageBlockSection>

	<apex:pageBlockButtons>
	<apex:commandButton action="{! save }" value="Save" />
	</apex:pageBlockButtons>

	</apex:pageBlock>

	<!-- Custom object B fields. -->
	<apex:pageBlock title="Create Two New Records">

opps sorry

The page should look like this then

<apex:page sidebar="false" standardStylesheets="false" standardController="Custom_Object_A__c" extensions="NewSurveyExtension">
<apex:form>


<apex:pageBlock>

<apex:pageBlockSection>
<apex:inputField value="{! Custom_Object_A__c.Name}"/>
</apex:pageBlockSection>

</apex:pageBlock>


<apex:pageBlock>

<apex:pageBlockSection>
<apex:inputField value="{! Custom_Object_A__c.Name}"/>
</apex:pageBlockSection>

</apex:pageBlock>

Tyler Zika

shouldn't the apex:inputField for B & C be this
<apex:inputField value="{! Custom_Object_B__c.Name}"/>
<apex:inputField value="{! Custom_Object_C__c.Name}"/>

Rao

10:23 PM
