Janno Rip Call Apex Class from Trigger after Update on Object
Hello everyone,
I guess this is as standard as it gets but I still struggle as newby in apex classes and triggers.
I have an apex class that - as for now - is being invoked by a process builder. But in regards of performance I want to switch to an apex trigger.
Here is the class:
Public class generateQuotePdfDocumentByTrigger{
//https://github.com/Rakeshistom/Auto-Generates-Quote-PDF
public static void QuoteCreate (List<Id> quoteIds) {
//Initialize the quote url
String quoteUrl = '/quote/quoteTemplateDataViewer.apexp?';
//Get the Quote Template Id from Custom Settings
String quoteTemplateId = Label.QuoteTemplateId;
//List variable to get all the Quote Documents
List<QuoteDocument> lstQuoteDoc = new List<QuoteDocument>();
if(!quoteIds.isEmpty() && quoteIds.size() > 0) {
for(Id quoteId :quoteIds) {
//Construct the quote URL to generate PDF
quoteUrl += 'id=' + quoteId;
quoteUrl += '&headerHeight=197&footerHeight=80';
quoteUrl += '&summlid=' + quoteTemplateId;
//call the quote url
PageReference pageRef = new PageReference(quoteUrl);
//get the quotePdf
Blob quoteBlob;
if(Test.isRunningTest()) {
quoteBlob = Blob.valueOf('Generate Pdf');
} else {
quoteBlob = pageRef.getContentAsPDF();
}
//initialze the QuoteDocument to hold the quote pdf for insertion
QuoteDocument quoteDoc = new QuoteDocument();
quoteDoc.Document = quoteBlob;
quoteDoc.QuoteId = quoteId;
lstQuoteDoc.add(quoteDoc);
}
}
if(!lstQuoteDoc.isEmpty() && lstQuoteDoc.size() > 0) {
Database.insert(lstQuoteDoc);
}
}
}
What I like the trigger to do is the following:After "Create_PDF__c" is set to "true" - invoke the apex class.
This is what I got so for but yeah...
Error: Compile Error: Method does not exist or incorrect signature: void generateQuotePdfDocumentByTrigger() from the type CreatePDFQuote_JTo at line 7 column 9
trigger CreatePDFQuote_JTo on Quote (after update)
{
for(Quote currentQuote : Trigger.New)
{
if(currentQuote.Create_PDF__c == true ) {
generateQuotePdfDocumentByTrigger();
}
}
}
Thanks in Advance!
trigger CreatePDFQuote_JTo on Quote (after update) { List<Id> quoteIds = new List<Id>(); for(Quote currentQuote : Trigger.New) { if(currentQuote.Create_PDF__c) { quoteIds.add(currentQuote.Id); } } if (quoteIds.size() > 0) { generateQuotePdfDocumentByTrigger.QuoteCreate (quoteIds); } }unfortunately I am running in the following error:
The flow tried to update these records: null. This error occurred: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY: CreatePDFQuote_JTo: execution of AfterUpdate caused by: System.VisualforceException: Getting content from within triggers is currently not supported. Class.generateQuotePdfDocumentByTrigger.QuoteCreate: line 33, column 1 Trigger.CreatePDFQuote_JTo: line 15, column 1.
@InvocableMethod public static void QuoteCreate(List<Id> quoteIds) { callFutureMethod(quoteIds); } @future(callout=true) public static void callFutureMethod (List<Id> quoteIds) { ... }It is now working and the class does what it should meaning creating PDFs. However I am creating 3 PDFs now at once for 1 quote. Is this due to (before update) ?
