HI, i am practicing for Salesforce developer 1.  I came across this question and the answer offered didnt make any sense to me.

The operation manager at a construction company uses a custom object called Machinery to manage the usage and maintenance of its cranes and other machinery. The manager wants to be able to assign machinery to different construction jobs, and track the dates and cost associated with each job. More than one piece of machinery can be assigned to one construction job. What should a developer do to meet these requirements?

1. Create a lookup field on the machinery object to the construction job object
2. Create a junction object with Master-Detail Relationship to both the machinery object and the construction job object.
3. Create a lookup field on the construction job object to the machinery object
4. Create a Master-Detail lookup field on the machinery object to the construction job object

The answer provided was n.3.  I would have gone with n.2.

Would you be able to help me with this and explain the answer to this by any chance

Many thanks
 

Hi,

I have a page listing all applications per job. the application object has a picklist field called ApplicationStatus__c.
We need to be able to select an applicationStatus for each of the applications and save it.
For some reason the selected value from the picklist is not being passed back to the controller.  and the value returned is the initial one ('New').  

public with sharing class JobCandidateController {

    public List <application__c> ListOfApplication {get; set;}
    public List<WrapperApplications> ApplicationWrappersList {get;set;}
   public List <WrapperApplications> ListOfApplicationWrapper {get; set;}

    
    
    private final candidate__c Cand;
    
    public string selectedValue { get; set; }
     
   
    
   
    public JobCandidateController() {       
        
       
       ListOfApplicationWrapper = new List<WrapperApplications>();
       ListOfApplicationWrapper = GetCandidateList();    
        
      
         system.debug ('******Selected VAlues are************ '+ ListOfApplicationWrapper);
       
             
        
    }

    public List <WrapperApplications> GetCandidateList() {
    
   
       
    ApplicationWrappersList = new List <WrapperApplications>();

                   = :ApexPages.currentPage().getParameters().get('id')];
                   
           for (application__c appl : ListOfApplication)
           
           {
           ApplicationWrappersList.add(new WrapperApplications(appl, getOptions() ,'New'));
           
           }
               
                   
              return ApplicationWrappersList;
    }
    
    
   

public List <selectoption> getOptions()
{

    
    Schema.DescribeFieldResult statusFieldDescription = Application__c.ApplicationStatus__c.getDescribe();  
        
   
    
    List<SelectOption> options = new List<SelectOption>();

    
    for (Schema.Picklistentry picklistEntry : statusFieldDescription.getPicklistValues())
    {
        options.add(new SelectOption(pickListEntry.getValue(),pickListEntry.getLabel()));
        system.debug ('******PickList VAlues are************ '+  pickListEntry.getValue());
        
    }
    
    return options;
}

     this.selectedValue = selectedValue;

       ca.app.ApplicationStatus__c = ca.selectedValue;
        //ca.ApplicationStatus__c = selectValue ;
        ListOfApplicationToUpdate.add(ca.app);
