Hi All , getting the error while completing this module. While my application is running correctly.

Error: Challenge Not yet complete... here's what's wrong: The campingList JavaScript helper isn't saving the new record to the database or adding it to the 'items' value provider.

I am copying code for the finding the bug.

Apex Class:
public class CampingListController {
	@auraenabled
    public static List<Camping_Item__c> getItems (){
        List<Camping_Item__c> CI = [select id, name,price__c,Quantity__c,Packed__c from Camping_Item__c ];
        return CI;
    }
    @auraenabled
    public static Camping_Item__c saveItem (Camping_Item__c CampingItem){
        insert campingItem;
        return campingItem;
    }

Hi Fernandez & Jeff,
 Thanks for your quick response. However the error is not with the js variable name . I have shifted the some code from CampingList.js to CampinListHelper.js . Now i completed the challenge. See the below updated code.

CampingList.js

    doInit  : function(component, event, helper) {
		var action = component.get("c.getItems");
        action.setCallback(this, function(response){

Hi,

Try changing 'lstItems' for 'items' in lines #26, #29 and #31 in CampingList.js

It worked for me! Let me know if it helps you!

We just updated this module with some new code. Please try the challenge check again. Sorry for the inconvenience.

I am getting "The campingList JavaScript controller isn't setting the 'item' as a parameter or saving the record correctly." even though the code is working and updating Salesforce as it should when a camping item is created
Richard Clarke - Artisan ConsultingRichard Clarke - Artisan Consulting
FYI in my campingListController.js I had to comment the call to "helper.createItem(component, item)" and move all that code into the controller then the challenge passed.  I did not change any code, just moved it from the helper to the controller.

It seems as though there was some confusion between "Camping" and "Campaign" on this one. I know that this issue has long-since been resolved, but I would be sure to correct the naming issue before continuing. In coding, small issues like these can create hours of work. 

Secondly, the helper did not appear to change anything. It received the information, but did nothing with it. That was all completed in the non-helper .js file. That could explain the error message: 

"Error: Challenge Not yet complete... here's what's wrong: The campingList JavaScript helper isn't saving the new record to the database or adding it to the 'items' value provider."

i was still encountering problems even after i checked the answers here
had a problem with the set params function for the action - i was using different name for the signature where calling the apex controller.
another problem was that updating view method block should have be placed in the helper and used only when the component is valid and and the response status is "SUCCESS"

I have also an issue with this.

My code works but cannot pass trailhead

 

campingListHelper.js

 

```

({
    createItem : function(item, action, component) {
        var items = component.get("v.items");
        
        action.setParams({
            "item" : item
        });

        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                
                items.push(item);
                component.set("v.items", items);
                component.set("v.newItem",{ 'sobjectType':
                                           'Camping_Item__c',
                                           'Name': '',
                                           'Quantity__c': 0,
                                           'Price__c': 0,
                                           'Packed__c': false });
            }
        });
            
        $A.enqueueAction(action);

    }
})

```

campingListController.js

 

```

({
    clickCreateItem : function(component, event, helper) {
        var validListItem = component.find('itemform').reduce(function(validSoFar, inputCmp){
            inputCmp.showHelpMessageIfInvalid();
            return validSoFar && inputCmp.get('v.validity').valid;
        }, true);    
        
        if (validListItem) {
            var currentItem = component.get("v.newItem");
            var newItem = JSON.parse(JSON.stringify(currentItem));
            var action = component.get("c.saveItem");  
            helper.createItem(newItem, action, component);
           
        }
    },
    doInit : function(component, event, helper) {
         // Create the action

            }
        });
        // Send action off to be executed
        $A.enqueueAction(action);
    }
})

```

 

CampingListController.apxc

```

public class CampingListController {    
    
    @AuraEnabled
    public static List<Camping_Item__c> getItems() {
        System.debug('Called get Items');
        List<Camping_Item__c> campingItems = [SELECT Name, Price__c, Quantity__c, Packed__c FROM Camping_Item__c];

           System.debug('error found'); 
        }
        
        return item;
        
    }
}

```

 

my error message is

```` 

Challenge not yet complete... here's what's wrong:
The campingList JavaScript helper doesn't appear to have the correct functionality. Ensure that it is saving the new record to the database and in the callback, pushing the new record to the array of existing items (e.g., v.items) and setting the modified array of items to the 'items' value provider to display the updated list.

 

```


thanks for any help!
