Hi,
the challenge is as follows :

Create a camping component that contains a campingHeader and a campingList component.
1.The campingList component contains an ordered list of camping supplies that include Bug Spray, Bear Repellant, and Goat Food.
2.The campingHeader component contains an H1 heading style with a font size of 18 points and displays 'Camping List'.

so i made a lightening application named "camping.app" having code :

<aura:application >
    <br/><br/><br/>
    <c:campingHeader/>
    <c:campingList/>  
</aura:application>


where lightening component "campingHeader.cmp" having code :

<aura:component >
    <h1> Camping List </h1>
</aura:component>

for I have "campingHeader.css" having code :
.THIS {
}

h1.THIS {
    font-size: 18px;
}

and lightening component "campingList.cmp" having code :

<aura:component >
    <ol>
       <li>Bug Spray</li>
       <li>Bear Repellant</li>
       <li>Goat Food</li>      
    </ol>
</aura:component>

when i preview the application it is working nice; but when checking the challenge it says :
"Challenge Not yet complete... here's what's wrong: 
The 'camping' Lightning Component does not include either the campingHeader or campingList component."

please help me know where I m doing wrong. Thanx waiting for your reply

Challenge - Create a form to enter new items and display the list of items entered. To make our camping list look more appealing, change the campingHeader component to use the SLDS. Similar to the unit, style the Camping List H1 inside the slds-page-header. Modify the campingList component to contain an input form and an iteration of campingListItem components for displaying the items entered.
The component requires an attribute named items with the type of an array of camping item custom objects.
The component requires an attribute named newItem of type Camping_Item__c with default quantity and price values of 0.
The component displays the Name, Quantity, Price, and Packed form fields with the appropriate input component types and values from the newItem attribute.
The JavaScript controller checks to ensure that the Name, Quantity and Price values submitted are not null.
If the form is valid, the JavaScript controller pushes the newItem onto the array of existing items, triggers the notification that the items value provider has changed, and resets the newItem value provider with a blank sObjectType of Camping_Item__c.


My answer - 
<aura:component >
<aura:attribute name="items" type="Camping_Item__c[]"/>
<aura:attribute name="newitem" type="Camping_Item__c[]"  default="{ 'sobjectType': 'Camping_Item__c',
                   'Quantity__c'=0, 'Price__c'=0}"/>
 <p>Name:
        <ui:inputText value="{!v.newitem.name}"/>
    </p>    
  <p>Packed:
        <ui:inputCheckbox value="{!v.newitem.Packed__c}"/>
     
    </p>    
  <p>Price:
        <ui:inputCurrency value="{!v.newitem.Price__c}"/>
    </p>
    <p>Quantity:
        <ui:inputNumber value="{!v.newitem.Quantity__c}"/>
    </p>
</aura:component>


Error -

Challenge Not yet complete... here's what's wrong: 
The campingList component isn't iterating the array of 'items' and creating 'campingListItem' components.

Please share the correct solution.

<!--campingListItem.cmp-->
<aura:component >
	<aura:attribute name="item" type="Camping_Item__c" required="true"/>

	<ui:outputText value="{!v.item.Name}" />
	<ui:outputCheckbox value="{!v.item.Packed__c}" />
	<ui:outputCurrency value="{!v.item.Price__c}" />
	<ui:outputNumber value="{!v.item.Quantity__c}" />
	<ui:button label="Packed!" press="{!c.packItem}"/>
	
</aura:component>

<!--campingListController.js-->
({
	packItem : function(component, event, helper) {
		var button = event.getSource().get("v.disabled");
		component.set("v.item.Packed__c", "true");
		component.set(button, "true");
	}
})

What am I doing wrong?

 

Hi, I am having trouble with the "Attributes and Expressions" module from trailhead.

Here is the challenge:
Create a Lightning Component to display a single item for your packing list.

• Create a component called campingListItem that displays the name (ui:outputText) and the three custom fields using the appropriate output components.
• Add an attribute named 'item' for type Camping_Item__c.

I created an component named campingListItem and this is the code:

<aura:component >
    <aura:attribute name="item" type="<my_domain>__Camping_Item__c"/>
    
    <ui:outputText value="{!v.item.Name}"/>
    <ui:outputCheckbox value="{!v.item.<my_domain>__Packed__c}"/>
    <ui:outputCurrency  value="{!v.item.<my_domain>__Price__c}"/>
    <ui:outputNumber value="{!v.item.<my_domain>__Quantity__c}"/>
</aura:component>

The error that I am getting is: "Challenge Not yet complete... here's what's wrong: 
The packingListItem Lightning Component's attribute tag doesn't exist or its attributes are not set correctly."

With this, I tried to create another component, with the name "packingListItem", but It didn't work.

Can anyone help me?

Thanks,

Hi,
I am not able to understand the below question correctly Please help me out. - 
Create a class that has a method accepting two strings. The method searches for contacts that have a last name matching the first string and a mailing postal code (API name: MailingPostalCode) matching the second. It gets the ID and Name of those contacts and returns them.The Apex class must be called 'ContactSearch' and be in the public scope.
The Apex class must have a public static method called 'searchForContacts'.
The 'searchForContacts' method must accept two incoming strings as parameters, find any contact that has a last name matching the first, and mailing postal code matching the second string. The method should return a list of Contact records with at least the ID and Name fields.
The return type for 'searchForContacts' must be 'List<Contact>'.
