Though inherited, the edit, delete, and save methods don't serve a function when used with the KnowledgeArticleVersionStandardController class.
The following example shows how a KnowledgeArticleVersionStandardController object can be used to create a custom extension controller. In this example, you create a class named AgentContributionArticleController that allows customer-support agents to see pre-populated fields on the draft articles they create while closing cases.
/** Custom extension controller for the simplified article edit page that appears when an article is created on the close-case page. */ public class AgentContributionArticleController { // The constructor must take a ApexPages.KnowledgeArticleVersionStandardController as an argument public AgentContributionArticleController( ApexPages.KnowledgeArticleVersionStandardController ctl) { // This is the SObject for the new article. //It can optionally be cast to the proper article type. // For example, FAQ__kav article = (FAQ__kav) ctl.getRecord(); SObject article = ctl.getRecord(); // This returns the ID of the case that was closed. String sourceId = ctl.getSourceId(); Case c = [SELECT Subject, Description FROM Case WHERE Id=:sourceId]; // This overrides the default behavior of pre-filling the // title of the article with the subject of the closed case. article.put('title', 'From Case: '+c.subject); article.put('details__c',c.description); // Only one category per category group can be specified. ctl.selectDataCategory('Geography','USA'); ctl.selectDataCategory('Topics','Maintenance'); } }
/** Test class for the custom extension controller. */ @isTest private class AgentContributionArticleControllerTest { static testMethod void testAgentContributionArticleController() { String caseSubject = 'my test'; String caseDesc = 'my test description'; Case c = new Case(); c.subject= caseSubject; c.description = caseDesc; insert c; String caseId = c.id; System.debug('Created Case: ' + caseId); ApexPages.currentPage().getParameters().put('sourceId', caseId); ApexPages.currentPage().getParameters().put('sfdc.override', '1'); ApexPages.KnowledgeArticleVersionStandardController ctl = new ApexPages.KnowledgeArticleVersionStandardController(new FAQ__kav()); new AgentContributionArticleController(ctl); System.assertEquals(caseId, ctl.getSourceId()); System.assertEquals('From Case: '+caseSubject, ctl.getRecord().get('title')); System.assertEquals(caseDesc, ctl.getRecord().get('details__c')); } }
