Emmanuel Corona attachment on new record
Greetings!
I have a custom object and a visualforce page for it.
On the page i would like to let the user create a new record and upload 2 files (2 attachments)
But i don't know how to catch the record id and then add the file to it....
Here is my code... I'll really appreciate your help.
Page:
<apex:page standardController="Arco__c" extensions="myArcoExtension,reCAPTCHA,AttachmentUploadController" title="Captura de Referenciados" showHeader="false" standardStylesheets="false">
<apex:composition template="{!$Site.Template}">
<apex:define name="body">
<apex:form >
<apex:messages id="error" styleClass="errorMsg" layout="table" style="margin-top:1em; background-color: #FF9300" />
<apex:pageBlock title="" mode="edit" id="sider2_header" >
<apex:pageBlockButtons rendered="{!(verified)}">
<apex:commandButton value="Enviar" action="{!savearco}" />
</apex:pageBlockButtons>
<apex:pageBlockSection title="Programa de Referenciados" collapsible="true" columns="1" >
Por favor, captura los datos de la persona que referencias:
<apex:inputField value="{!Arco__c.Name}" label="Nombre (s)" required="True" style="width: 200px; height: auto; background-color: #E0FFFF" styleclass="input"/>
<apex:inputCheckbox value="{!Arco__c.Aceptaci_n__c}"/>
<apex:outputText value="Arco: "/><apex:inputText value="{!parentId}"/><br/>
<apex:outputText value="Archivo: "/><apex:inputFile value="{!attach.body}" filename="{!attach.name}"/><br/>
<apex:commandButton value="Adjuntar" action="{!upload}"/>
Class
public class myArcoExtension
{
private final Arco__c webarco;
public myArcoExtension(ApexPages.StandardController stdController)
{
webarco = (Arco__c)stdController.getRecord();
}
public myArcoExtension(){}
public PageReference saveArco()
{
try {
insert(webarco);
}
catch(System.DMLException e)
{
ApexPages.addMessages(e);
return null;
}
PageReference p = Page.informacion_enviada;
p.setRedirect(true);
return p;
}
ublic with sharing class AttachmentUploadController
{
public AttachmentUploadController(ApexPages.StandardController controller) {
}
public String parentId {get;set;}
public Attachment attach {get;set;}
public AttachmentUploadController()
{
attach = new Attachment();
}
public ApexPages.Pagereference upload()
{
attach.ParentId = parentId;
insert attach;
return new ApexPages.Standardcontroller(attach).view();
}
}
this means you have to add the code inside this
public myArcoExtension(ApexPages.StandardController stdController)
{
webarco = (Arco__c)stdController.getRecord();
attach = new Attachment();
}

Whenever you are doing a insert call on a sobject, the Id gets automatically updated in the Sobject Id Field
So after insert call you will get id in "webarco.Id"
Hello Avidev9!
Thank you for you response, so I only need to to replace the parent id for webarco.id???
Just make sure you do it after insert call.
mmmm maybe i'm not understanding ....
I change :
attach.ParentId = parentId; on the AttachmentUploadController class and i get a compilation error Variable does not exist: webarco.id
Or maybe i'm not explaining well...
I have a class for insert the new record called myArcoExtension.... at this time this only insert.
I have another class called AttachmentUploadController... it only works if i have the record id.
On the page i have only a field (at the moment) asking for the Arco Name, and a field for one attachment... when i press the save button i get an error because i don't have the record id to attach the file...
I'll really appreciate if you can explain me more a detail.
Ok let me try to do that :) i really appreciate your help with this thing, maybe is so easy but i'm new in sfdc and visualforce world XD
Hello Friend!
Please can you tell me if the logic is now ok before move the code ?
public class myArcoExtension
{
public Id recId
{ get;set; }
private final Arco__c webarco;
public myArcoExtension(ApexPages.StandardController stdController)
{
webarco = (Arco__c)stdController.getRecord();
}
public Attachment attach {get;set;}
public myArcoExtension(){}
public PageReference saveArco()
{
try {
insert(webarco);
attach = new Attachment();
attach.ParentId = webarco.id;
insert attach;
return new ApexPages.Standardcontroller(attach).view();
}
catch(System.DMLException e)
{
ApexPages.addMessages(e);
return null;
}
PageReference p = Page.informacion_enviada;
p.setRedirect(true);
return p;
}
/* Clase testMethod para validar el código y cubrir el porcentaje de cobertura */
public static testMethod void myTest() {
Lead lead = new Lead();
lead.FirstName = 'Emmanuel';
lead.LastName = 'Corona';
lead.Company = 'MCM Telecom';
insert lead;
//Create the controller
ApexPages.StandardController sc = new ApexPages.StandardController(lead);
//Create the instances of the controller
myArcoExtension myPageTest = new myArcoExtension();
myArcoExtension myPageTestSC = new myArcoExtension(sc);
myPageTestSC.saveArco();
}
}
Just merge all the functions and variables keep everything intact.
and replcae the parent with "webarco.id"
I'm doing things wrong... i get errors when i merge the class...
Here is the class for insert
public class myArcoExtension
{
public Id recId
{ get;set; }
private final Arco__c webarco;
public myArcoExtension(ApexPages.StandardController stdController)
{
webarco = (Arco__c)stdController.getRecord();
}
public myArcoExtension(){}
public PageReference saveArco()
{
try {
insert(webarco);
}
catch(System.DMLException e)
{
ApexPages.addMessages(e);
return null;
}
PageReference p = Page.informacion_enviada;
p.setRedirect(true);
return p;
}
/* Clase testMethod para validar el código y cubrir el porcentaje de cobertura */
public static testMethod void myTest() {
Lead lead = new Lead();
lead.FirstName = 'Emmanuel';
lead.LastName = 'Corona';
lead.Company = 'MCM Telecom';
insert lead;
//Create the controller
ApexPages.StandardController sc = new ApexPages.StandardController(lead);
//Create the instances of the controller
myArcoExtension myPageTest = new myArcoExtension();
myArcoExtension myPageTestSC = new myArcoExtension(sc);
myPageTestSC.saveArco();
}
}
Here is the class to upload
public with sharing class AttachmentUploadController
{
public AttachmentUploadController(ApexPages.StandardController controller) {
}
public String parentId {get;set;}
public Attachment attach {get;set;}
public AttachmentUploadController()
{
attach = new Attachment();
}
public ApexPages.Pagereference upload()
{
attach.ParentId = parentId;
insert attach;
return new ApexPages.Standardcontroller(attach).view();
}
}
I get error like the public upload function is not correct and other like unexpected token
Can you explaine me? :)
public Attachment attach {get;set;}
public ApexPages.Pagereference upload()
{
attach.ParentId = parentId;
insert attach;
return new ApexPages.Standardcontroller(attach).view();
}
just copy the stuff to the other controller and add this line in the constructor "attach = new Attachment();"
Ok i have this now
public class myArcoExtension
{
public Id recId
{ get;set; }
private final Arco__c webarco;
public myArcoExtension(ApexPages.StandardController stdController)
{
webarco = (Arco__c)stdController.getRecord();
}
public myArcoExtension(){}
public PageReference saveArco()
{
try {
insert(webarco);
}
catch(System.DMLException e)
{
ApexPages.addMessages(e);
return null;
}
PageReference p = Page.informacion_enviada;
p.setRedirect(true);
return p;
}
public String parentId {get;set;}
public Attachment attach {get;set;}
public ApexPages.Pagereference upload()
{
attach.ParentId = parentId;
insert attach;
return new ApexPages.Standardcontroller(attach).view();
}
/* Clase testMethod para validar el código y cubrir el porcentaje de cobertura */
public static testMethod void myTest() {
Lead lead = new Lead();
lead.FirstName = 'Emmanuel';
lead.LastName = 'Corona';
lead.Company = 'MCM Telecom';
insert lead;
//Create the controller
ApexPages.StandardController sc = new ApexPages.StandardController(lead);
//Create the instances of the controller
myArcoExtension myPageTest = new myArcoExtension();
myArcoExtension myPageTestSC = new myArcoExtension(sc);
myPageTestSC.saveArco();
}
}
The record is now inserted.... but the attachment is not there... i don't get any error message... :(
I thought we replaced this line "attach.ParentId = parentId;" with the record id (webarco .Id)
And how are you calling the upload method ?
The class is:
public class myArcoExtension
{
private final Arco__c webarco;
public myArcoExtension(ApexPages.StandardController stdController)
{
webarco = (Arco__c)stdController.getRecord();
}
public myArcoExtension(){}
public PageReference saveArco()
{
try {
insert(webarco);
}
catch(System.DMLException e)
{
ApexPages.addMessages(e);
return null;
}
PageReference p = Page.informacion_enviada;
p.setRedirect(true);
return p;
}
public String parentId {get;set;}
public Attachment attach {get;set;}
public ApexPages.Pagereference upload()
{
attach.ParentId = webarco.id;
insert attach;
return new ApexPages.Standardcontroller(attach).view();
}
/* Clase testMethod para validar el código y cubrir el porcentaje de cobertura */
public static testMethod void myTest() {
Lead lead = new Lead();
lead.FirstName = 'Emmanuel';
lead.LastName = 'Corona';
lead.Company = 'MCM Telecom';
insert lead;
//Create the controller
ApexPages.StandardController sc = new ApexPages.StandardController(lead);
//Create the instances of the controller
myArcoExtension myPageTest = new myArcoExtension();
myArcoExtension myPageTestSC = new myArcoExtension(sc);
myPageTestSC.saveArco();
}
}
And in the page i have this...
<apex:page standardController="Arco__c" extensions="myArcoExtension" title="Interesado en Contratar Servicios de MCM" showHeader="false" standardStylesheets="true">
<apex:composition template="{!$Site.Template}">
<apex:define name="body">
<apex:form >
<apex:messages id="error"
styleClass="errorMsg"
layout="table"
style="margin-top:1em;"/>
<apex:pageBlock title="" mode="edit">
<apex:pageBlockButtons >
<apex:commandButton value="Save"
action="{!savearco}"/>
</apex:pageBlockButtons>
<apex:pageBlockSection title="Contact Us"
collapsible="false"
columns="1">
<apex:inputField value="{!Arco__c.Name}"/>
<apex:outputText value="Archivo: "/><apex:inputFile value="{!attach.body}" filename="{!attach.name}"/><br/>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:define>
</apex:composition>
</apex:page>
that essentially means you never inserted the attachment
I thought that the save method will call it in automatic...
So what do you suggest me??? i don't know how i could call the upload method :(
is possible to add two action in one single button???? i tried it but i i could not make it possible ... Thank you so much for your support and patience
Use this
public PageReference saveArco() { try { insert(webarco);upload(); } catch(System.DMLException e) { ApexPages.addMessages(e); return null; } PageReference p = Page.informacion_enviada; p.setRedirect(true); return p; }
I get the next error
Attempt to de-reference a null object
El error está en la expresión '{!savearco}' del componente <apex:page> en page arco2
public PageReference saveArco()
{
try {
insert(webarco);
upload();
}
and here
attach.ParentId = webarco.id;
this means you have to add the code inside this
public myArcoExtension(ApexPages.StandardController stdController)
{
webarco = (Arco__c)stdController.getRecord();
attach = new Attachment();
}
My friend you are a master!!!!
Is working now!!!
Thank you thank you thank you so much!!!! I really appreciate your help :D
