Hi folks,
My  custom object (Test) which contains (name ,phone number and email fields)and the records inside the test object only visible to the my team leader and his manager..other user,leader and manager cannot view those record in test objects. for that I've created Apex trigger:

trigger Test_Share on Test__c (after insert) {

Id i=UserInfo.getUserId();

//ID groupId = [select id from Group where Type = 'Organization'].id;

if(trigger.isInsert){

List<Test__Share> testShare= new List<Test__Share>();
     for(Test__c t : trigger.new){

        Test__Share ts = new Test__Share();


        ts.ParentId = t.Id;
        ts.UserOrGroupId = ParrentIdClass.getParrentId(i);



        ts.AccessLevel = 'edit';

        ts.RowCause = Schema.Test__Share.RowCause.Test_Access__c;
        testShare.add(ts);
    }
Database.SaveResult[] TestShareInsertResult = Database.insert(testShare,false);
}
}

Apex Class: public class ParrentIdClass {

public static Id getParrentId(Id i){
    String ParentUserName;
    Id ParentUserId;
    User u = new User(id=i);
    u = [select u.UserRoleId from User u where u.Id =: UserInfo.getUserId()];

    System.debug('UserRoleId='+u.UserRoleId);


    UserRole ur = new UserRole(id=u.UserRoleId);
  ur = [select ur.Id, ur.Name, ur.ParentRoleId from UserRole ur where ur.Id =: u.UserRoleId];


    System.debug('UrId='+ur.Id);
System.debug('UrName='+ur.Name);
System.debug('UrParentRoleId='+ur.ParentRoleId);


    if (ur.ParentRoleId != null){
        //  check if there's a ParentRole
      UserRole ur1 = new UserRole(id=ur.ParentRoleId);
      ur1 = [select ur1.Id, ur1.Name, ur1.ParentRoleId from UserRole ur1 where ur1.Id =: ur.ParentRoleId];
    System.debug('UrId='+ur1.Id);
  System.debug('UrName='+ur1.Name);
  System.debug('UrParentRoleId='+ur1.ParentRoleId);
      if(ur1.ParentRoleId != null){
          //  last level in the hierarchy
          UserRole ur2 = new UserRole(id=ur1.ParentRoleId);
          ur2 = [select ur2.Id, ur2.Name, ur2.ParentRoleId from UserRole ur2 where ur2.Id =: ur1.ParentRoleId];
          System.debug('UrId='+ur2.Id);
    System.debug('UrName='+ur2.Name);
    System.debug('UrParentRoleId='+ur2.ParentRoleId);
            ParentUserId=ur2.Id;
            return ParentUserId;
      }
         else{
          // no more ParentRoleId
          ParentUserId=ur1.Id;
           return ParentUserId;
        }
     }
    else{
      // no ParentRoleId
      ParentUserId=ur.Id;
        return ParentUserId;
  }
}
}

But it doesnt work for my scenario..

Please Help!
