How to redirect to master page?

hi friends,

i have created two objects 1)Job 2)Job Task

and there is a master detail relationship between Job and JobTask...

i have created visualforc page to create new Job and Jobtask as well...

i am getting problem while deleting Job Task from its Detail page... Because after deleting it goes to standard list of jobtask...

i want that after deleting any jobtask it should go back to respected Job... i have written apex for this but not able to fetch id of master record...

could any one provide me code to override delete of job task

 

here is my code but not able to retrieve id ob JOB

 

 

public class DeleteJobTask
{
    private final JobTask__c objJT;
    public DeleteJobTask(ApexPages.StandardController controller)
    {
    this.objJT=(Holiday__c)controller.getrecord();
    }
     public PageReference checkDelete()
     {
        try
        {
        Database.delete(objJT);       
        }
        catch(System.DMLException e)
        {
        return null;
        }
        PageReference p =  new Pagereference('/apex/JobDetailPage?id=);
        p.setRedirect(true);
        return p;
     }

}

hmm, field is not been added in the query in this line : Class.DeleteSpecItem.checkDelete: line 18,.

so either add the field in that query or I'm not sure here but give below code a try:

 

public class DeleteJobTask
{
    public Id JobId;
    private final JobTask__c objJT;
    public DeleteJobTask(ApexPages.StandardController controller)
    {
    this.objJT=(Holiday__c)controller.getrecord();
    }
     public PageReference checkDelete()
     {
       JobId = [Select Id, Job__c from Holiday__c where Id =:objJT.Id limit 1].Job__c;
        try
        {
        Database.delete(objJT);       
        }
        catch(System.DMLException e)
        {
        return null;
        }
        PageReference p =  new Pagereference('/apex/JobDetailPage?id='+JobId);
        p.setRedirect(true);
        return p;
     }

This can be done, Before deleting a JobTask, store the Id of its Job and after deleting, redirect to that id.

Like:

 

public class DeleteJobTask
{
    public Id JobId = new Id();
    private final JobTask__c objJT;
    public DeleteJobTask(ApexPages.StandardController controller)
    {
    this.objJT=(Holiday__c)controller.getrecord();
    }
     public PageReference checkDelete()
     {
        if(objJT != null && objJT.Job__c!= '') 
            JobId = objJT.Job__c; // Replace Job__c with actual lookup field name.
        try
        {
        Database.delete(objJT);       
        }
        catch(System.DMLException e)
        {
        return null;
        }
        PageReference p =  new Pagereference('/apex/JobDetailPage?id='+JobId);
        p.setRedirect(true);
        return p;
     }

}

 Hope it helps.
