Using lightning:flow
component, we can invoke a flow in Lightning runtime. This component requires API version 41.0 and later. Here is an example to delete all Contact records from an Account using a flow.
Here I’ve created a flow and the flow is invoked by a lightning component, and that lightning component is configured with a QuickAction on Account object.
1. Go to Setup | Quick Find – Search Flows | New Flow
2. Create a variable as “AccountId”
3. Create a sObject Collection Variable as “CollectionOfContacts”
4. Create a Fast Lookup to get Contacts with Account Id
5. Create a Decision to check Account has contacts.
6. Default Outcome in Decision
7. Create Fast Delete to delete Contacts
8. Set the Fast Lookup as a starting element, indicated by the green down arrow. Then, connect the flow element “Fast Lookup” to “Decision” and “Decision” to “Fast Delete”.
9. Create a Lightning Component to invoke the flow.
Lightning component:
<aura:component implements="force:lightningQuickActionWithoutHeader,flexipage:availableForRecordHome,force:hasRecordId"> <!--Custom Styles for Modal Header and Footer--> <aura:html tag="style"> .cuf-content { padding: 0 0rem !important; } .slds-p-around--medium { padding: 0rem !important; } .slds-modal__content{ overflow-y:hidden !important; height:unset !important; max-height:unset !important; } </aura:html> <!--Declare Attributes--> <aura:attribute name="hasError" type="Boolean" default="false"/> <!--Modal Header--> <div class="modal-header slds-modal__header slds-size_1-of-1"> <h4 class="title slds-text-heading--medium">Delete Contacts</h4> </div> <!--End Modal Header--> <!--Modal Body--> <div class="slds-modal__content slds-p-around--x-small slds-align_absolute-center slds-size_1-of-1 slds-is-relative"> <form class="slds-form--stacked"> <aura:if isTrue="{!!v.hasError}"> <div class="slds-align_absolute-center"> Do you want to delete all contacts? </div> <aura:set attribute="else"> <div> <div class="slds-text-color_error">Error on Contact record deletion. Please forward following error message to your admin:</div> </div> </aura:set> </aura:if> <div> <!--Lightning Flow Attribute--> <lightning:flow aura:id="deleteContactFlow" onstatuschange="{!c.statusChange}"/> </div> </form> </div> <!--End of Modal Body--> <!--Modal Footer--> <div class="modal-footer slds-modal__footer slds-size_1-of-1"> <lightning:button variant="Brand" class="slds-button" label="Confirm" onclick="{!c.handleConfirm}"/> <lightning:button variant="Neutral" class="slds-button" label="Cancel" onclick="{!c.handleClose}"/> </div> <!--End of Modal Footer--> </aura:component>
Lightning JS Controller:
({ //Confirm handleConfirm : function(component, event, helper) { //Find lightning flow from component var flow = component.find("deleteContactFlow"); //Put input variable values var inputVariables = [ { name : "AccountId", type : "String", value : component.get("v.recordId") } ]; //Reference flow's Unique Name flow.startFlow("Delete_Contact_From_Account", inputVariables); }, //Close the quick action handleClose : function(component, event, helper) { $A.get("e.force:closeQuickAction").fire(); }, //Flow Status Change statusChange : function (component, event, helper) { //Check Flow Status if (event.getParam('status') === "FINISHED_SCREEN" || event.getParam('status') === "FINISHED") { var toastEvent = $A.get("e.force:showToast"); toastEvent.setParams({ title: "Success!", message: "Contacts deleted successfully!", type: "success" }); toastEvent.fire(); $A.get("e.force:closeQuickAction").fire(); $A.get('e.force:refreshView').fire(); } else if (event.getParam('status') === "ERROR") { component.set("v.hasError", true); } } })
10. Configure above created lightning component on Account object Quick Action.
11. Add created quick action on Account object page layout.
12. Here is the quick action to delete all contacts.
