Hello everyone I could use some help on the using future Methods trailhead. Please keep in mind I am not an Apex coder at all but I am trying to learn as much as I can.

Here is the Task

Create an Apex class with a method using the @future annotation that accepts a List of Account IDs and updates a custom field on the Account object with the number of contacts associated to the Account. Write unit tests that achieve 100% code coverage for the class.
Create a field on the Account object called 'Number_of_Contacts__c' of type Number. This field will hold the total number of Contacts for the Account.
Create an Apex class called 'AccountProcessor' that contains a 'countContacts' method that accepts a List of Account IDs. This method must use the @future annotation.
For each Account ID passed to the method, count the number of Contact records associated to it and update the 'Number_of_Contacts__c' field with this value.
Create an Apex test class called 'AccountProcessorTest'.
The unit tests must cover all lines of code included in the AccountProcessor class, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.

I have written an Apex class and a Test class but I think I am doing them both Wrong: because when I try to check the challenge i Get this error

Challenge Not yet complete... here's what's wrong: 
The 'AccountProcessorTest' test class doesn't appear to be calling the 'AccountProcessor.countContacts' method between Test.startTest() and Test.stopTest().


When I run the Test class I get this error :

System.QueryException: List has no rows for assignment to SObject

Here is the CLASS:
 
public class AccountProcessor {
     @future

  public static void someFutureMethod(List<id> scope) {

   Account[] updates = new Account[] {};
        for (AggregateResult ar : [
                select AccountId a, count(Id) c
                from Contact
                where AccountId in :scope
                group by AccountId
                ]) {
            updates.add(new Account(
                    Id = (Id) ar.get('a'),
                    Number_of_Contacts__c = (Decimal) ar.get('c')
                    ));
        }
        update updates;
    }

}

Here is the Test Class:
 
@IsTest
public class AccountProcessorTest {
  public static testmethod void TestAccountProcessorTest() {
 
Test.startTest();
     Account a = new Account();
        a.Name = 'Test Account';
        Insert a;
      
      Contact cont = New Contact();
      
      cont.FirstName ='Bob';
      cont.LastName ='Masters';
      cont.AccountId = a.Id;
      Insert cont;

    Test.stopTest() ;
     Contact ACC = [select AccountId from Contact where id = :a.id LIMIT 1];

 
        System.assert(Cont.AccountId != null);
        System.assertequals(cont.id, ACC.AccountId);

  }}

I have used alot or diffrent google searches to get me this far. But I have not Idea if Im even remotly close to the right answer or not.


 
On the using basic in checking Formula challege. I have done the challege and tested the results but I cant get it to validate that its correct. I have re written the formula Multiple times now and everytime when I test it the validation fires as expected. But I can get it to validate through trailhead. I get the following error.

"Challenge Not yet complete... here's what's wrong: 
The validation rule does not reference the 'IsClosed' and 'CloseDate' fields correctly. Take a look at the requirements again."

Here is the challenge:

Your number-crushing sales team has so many deals in the pipeline, you’re starting to see occasional problems with data quality. Namely, sales reps are forgetting to update the close date to a date in the future. Make a formula that requires an opportunity to have a CloseDate of today or any future date. Hint: this formula should reference the hidden IsClosed checkbox field on the Opportunity object, and you will be creating the formula as an Opportunity validation rule.The validation rule should be on the Opportunity object
The validation rule should be named 'Close_Date_Alert'
The validation rule should fire if IsClosed is not selected and CloseDate is yesterday or earlier
The validation rule should display the error 'Hey McFly, unless you are planning to go back in time, please update your close date' at the top of the page when triggered


Here is the formula I currently have in there:


CloseDate < TODAY() && NOT(IsClosed)

I have probably written this like 10 diffrent ways and cant get it to properly validate.


 
please help me ....

Two team members need to view and update Accounts, but only one should be able to see and edit the Rating field. Create one profile and one permission set with field level security to solve for this use case.The profile must be named 'Basic Account User' and result in an API name of 'Basic_Account_User'. It should use the 'Salesforce' user license type.
The permission set must be named ‘Account Rating’ and result in an API name of 'Account_Rating'.Check Challenge
Using a Standard List Controller, create a Visualforce page which displays a list of Accounts with links to their respective record detail pages.The page must be named 'AccountList'.
It must reference the Account standard controller.
It must have a recordSetVar equal to 'accounts'.
It must have a Visualforce apex:repeat component.
The repeater must have the var attribute set to 'a'.
The repeater must use the <li> HTML list tag
The repeater must use the apex:outputLink component to link to the respective record detail page
HINT: Record detail pages can be reached by placing a record ID at the root of the URL (e.g. '/<record id>')

I tried this code i am able to retrieve the records and clicking on each record showing  the detail page of that record.But Still Trail Head is showing error.Can someone guide me if  I am wrong


<apex:page standardController="Account" recordSetVar="accounts">
    <apex:pageBlock title="Accounts">
      <apex:repeat value="{!Accounts}" var="a">
      <li>
       <apex:outputLink value="{!URLFOR($Action.Account.view, a.id)}">{!a.Name}
       </apex:outputLink>
     </li>
   </apex:repeat>
   </apex:pageBlock> 
</apex:page>
 
Hello developer heroes!

I'm working through the Apex modules on Trailhead and can't seem to get past this one: https://developer.salesforce.com/en/trailhead/force_com_programmatic_beginner/apex_triggers/apex_triggers_bulk.

Hopefully this doesn't read like a 'please complete the course for me' kinda post, but I have written a trigger that I believe meets the criteria but it isn't passing the check, so I wanted to seek the guidance of the experts.

The challenge is to do this:

Create an Apex trigger for Opportunity that adds a task to any opportunity set to 'Closed Won'.

To complete this challenge, you need to add a trigger for Opportunity. The trigger will add a task to any opportunity inserted or updated with the stage of 'Closed Won'. The task's subject must be 'Follow Up Test Task'.The Apex trigger must be called 'ClosedOpportunityTrigger'

- With 'ClosedOpportunityTrigger' active, if an opportunity is inserted or updated with a stage of 'Closed Won', it will have a task created with the subject 'Follow Up Test Task'.
- To associate the task with the opportunity, fill the 'WhatId' field with the opportunity ID.
- This challenge specifically tests 200 records in one operation.


And here is the trigger I have come up with, which compiles OK and stands up to a manual (though admittedly unbulkified) test:
trigger ClosedOpportunityTrigger on Opportunity (after insert, after update) {

    List<Task> taskList = new List<Task>();
    
    for (Opportunity opp : [SELECT Id, StageName FROM Opportunity WHERE StageName = 'Closed Won' AND Id IN :Trigger.new]){
                    
            taskList.add(new Task(Subject = 'Follow Up Test Task',
                                  WhatId = opp.Id));
       
    }

    if(taskList.size()>0){
        
        insert taskList;
        
    }
    
}
I have tried replacing the SOQL with a straightforward 'for (Opportunity opp : Trigger.new)' and having the taskList.add inside an IF that checks for Closed Won - no luck. I also thought about checking to see if the stage was being changed to Closed Won, rather than the trigger firing on every edit, but I don't think this is what the module is asking for.

Where do you think I'm going wrong?

Huge thanks in advance!

Hi,

On a workflow, I am concatenating Subject and Description on Case; I would like to add a line break between the two, but none of the following work :

 

Subject + "\n" + Description

Subject + '\n' + Description

Subject + "<br>" + Description

 

What should I use ?
