Hi 
I have one custom object margin_calculator_... and this object have lookup of Opportunity.when we update Opportunity at a particular stage here [ stagename-'Margin cal...' () ]in this stage if there is at least one record in my custom object margin_calculator_... it should allow to update oppty at this stage or if there is no custom object records for that oppty it should not allow to update oppty at that stage.
i tried too much but not able to do in both condion.my code is working 
but something is missing please help me out.
Thanks in advance.
your help will be appericiated.

my code is as follows-
trigger OpportunityTrigger on Opportunity (before update) {
    List<Margin_Calculator_Version__c> marginLst =new List<Margin_Calculator_Version__c>();    
    marginLst = [SELECT Id, Name, Opportunity__r.Id FROM Margin_Calculator_Version__c WHERE Opportunity__r.Id IN :Trigger.new]; 
    
        
        
        for(Opportunity opp:Trigger.new){
            for(Margin_Calculator_Version__c marginversion:marginLst){
                Set<Id> oppId = new Set<Id>();
                
                oppId.add(marginversion.Opportunity__r.Id);
                
               
               
                if((oppId.Contains(opp.Id)) && (opp.StageName=='Margin Calculation'))
                {
                    
                    update opp;
                }else{
                    
                    opp.addError('Please create one record in margin version');
                }
                
                
           
        }
        
    }
    
}
    
    

 

hi
 I have custom object for Quote,opportunitylineitem,product and so on....
my requirement is to -1.only one quote should be synced with opportunity.
                      2.first delete the opportunity product list than add the line item
                        of synced Quote.
                      3.The quote line item for that(synced) quote should be populated
                        into the related opportunity product(opplineitem)

Relation ship in my objects are
 Quote-----Opportunity--Masterdetail and lookup
 Quote----Quotelineitem--Master Detail
Quotelineitem----Opportunity-- lookup
OpportunityProduct-------Quotelineitem--look up
OpportunityProduct----Opportunity--Masterdetail
OpportunityProduct-----Product-- lookup

i had achieved first(1) and second(2) but not third(3).i had written code for third condition also
but it is not working.
my handler and trigger is here

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,
