Hi All,

I have list of candidates  for batch.so I have to assign task to them.for giving task,I have to select the students and once click continue,task should be assigned to selected candidates. and should show only remaining unselected students,so that we can assign task to remaining students.

I am able to do this but once selected one student and task is inserted for that student and next i select another student and trying to insert,The task is assigning to first student which i selected previously and inserting again.means the list is not cleared .can any one help me in this .below is my code.

Hi,
I have a scenario where on account we have a field called primarychild text box and in contacts of account  we have ischild checkbox field,if ischild is checked for one contact and the ischild should be false for remaining contacts of that account  and checked contact lastname should be displayed on account primarychild text box. 
I have tried but I am not able solve it.

As i am new to coding I can able to analyse but not able to implement .here is my code  where i tried to get record of contacts based on account id and for every account I am checking its contacts and if  ischild is updated to true old records should be false. 

trigger checkonecontact on Contact (before update) {

Set<Id> s=new Set<Id>();

for(contact c:trigger.old){
   s.add(c.accountId);
}


Map<id,contact> cmap=new Map <id,contact>([select name,childeligible__c,account.accountchild__c  from contact where accountId in:s]);

for(account a:[select name,accountchild__c from account where id in:s]){
        Contact obj = cmap.get(c.id);


}


}



 

I have wrote a trigger that display error if rating ==hot,for this trigger I wrote testclass but I am getting testclass fail showing following error.
and it is also showing other trigger Trigger.updateAccount,why?can anyone help me 

System.AssertException: Assertion Failed: Expected: The Last Name "hot" is not allowed for DML, Actual: updateAccount: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object Trigger.updateAccount: line 2, column 1

Hi All,

Below is the trigger where when contacts are created, there is field called Count_of_Contacts__c  in account which counts no of contacts and display in account field Count_of_Contacts__c.In this I have a doubt regarding map,Please explain me.  

mapcon.put(c.accountid,listcon.size());//In this line we are putting accountids which are in contact object,to get the size of contacts
mapcon.get(ac.id)​       //in this line we are using account reference and getting id for size,but we have to call like this                      know mapcon.get(c.accountid) to get the size,because we have created map which taking accountids of contact,but how it is taking ac.id which is in account for getting size.


trigger contactcountaccount on Contact (after insert) {
list<Id> listContact = new list<Id>();
list<contact> listcon=new list<contact>();
list<account> listAcc= new list<account>(); 

set<Id> s=new set<Id>();
for(contact c:trigger.new){
s.add(c.accountid);
}

list<account> accountId = [select id,name,Count_of_Contacts__c from account where id in:s];
list<contact> contactId=  [select id,accountid,name from contact where accountid in:s];
map<id,Integer> mapcon=new map<id,Integer>();


for(account A:accountId)
{
for(contact C: contactId){
if(c.accountid==a.id){
listcon.add(c);
system.debug('this are list of contacts if ids are equal'+listcon);
mapcon.put(c.accountid,listcon.size());           //please explain
system.debug('this are map of con accountid and consize '+mapcon);


 }
}
}
if(listcon.size()>0){
for(account ac:accountId){
if(mapcon.get(ac.id)==null){                    //please explain
system.debug('GET account id into map'+mapcon.get(ac.id));

ac.Count_of_Contacts__c =0;
}
else{
ac.Count_of_Contacts__c = mapcon.get(ac.id);
system.debug('getting how many contacts with id'+ac.Count_of_Contacts__c);

}
listAcc.add(ac);

}

}

if(listAcc.size()>0)
update listAcc

Hi,
I have a scenario where on account we have a field called primarychild text box and in contacts of account  we have ischild checkbox field,if ischild is checked for one contact and the ischild should be false for remaining contacts of that account  and checked contact lastname should be displayed on account primarychild text box. 
I have tried but I am not able solve it.

As i am new to coding I can able to analyse but not able to implement .here is my code  where i tried to get record of contacts based on account id and for every account I am checking its contacts and if  ischild is updated to true old records should be false. 

trigger checkonecontact on Contact (before update) {

Set<Id> s=new Set<Id>();

for(contact c:trigger.old){
   s.add(c.accountId);
}


Map<id,contact> cmap=new Map <id,contact>([select name,childeligible__c,account.accountchild__c  from contact where accountId in:s]);

for(account a:[select name,accountchild__c from account where id in:s]){
        Contact obj = cmap.get(c.id);


}


}

Hi All,

Below is the trigger where when contacts are created, there is field called Count_of_Contacts__c  in account which counts no of contacts and display in account field Count_of_Contacts__c.In this I have a doubt regarding map,Please explain me.  

mapcon.put(c.accountid,listcon.size());//In this line we are putting accountids which are in contact object,to get the size of contacts
mapcon.get(ac.id)​       //in this line we are using account reference and getting id for size,but we have to call like this                      know mapcon.get(c.accountid) to get the size,because we have created map which taking accountids of contact,but how it is taking ac.id which is in account for getting size.


trigger contactcountaccount on Contact (after insert) {
list<Id> listContact = new list<Id>();
list<contact> listcon=new list<contact>();
list<account> listAcc= new list<account>(); 

set<Id> s=new set<Id>();
for(contact c:trigger.new){
s.add(c.accountid);
}

list<account> accountId = [select id,name,Count_of_Contacts__c from account where id in:s];
list<contact> contactId=  [select id,accountid,name from contact where accountid in:s];
map<id,Integer> mapcon=new map<id,Integer>();


for(account A:accountId)
{
for(contact C: contactId){
if(c.accountid==a.id){
listcon.add(c);
system.debug('this are list of contacts if ids are equal'+listcon);
mapcon.put(c.accountid,listcon.size());           //please explain
system.debug('this are map of con accountid and consize '+mapcon);


 }
}
}
if(listcon.size()>0){
for(account ac:accountId){
if(mapcon.get(ac.id)==null){                    //please explain
system.debug('GET account id into map'+mapcon.get(ac.id));

ac.Count_of_Contacts__c =0;
}
else{
ac.Count_of_Contacts__c = mapcon.get(ac.id);
system.debug('getting how many contacts with id'+ac.Count_of_Contacts__c);

}
listAcc.add(ac);
system.debug('final list listAcc'+listAcc);

}

}

if(listAcc.size()>0)
update listAcc

I wrote a class when record is inserted it is redirected to another page and should display that record as output field.I wrote a test class for first class,but i dont know how to write test class for pagereference and 2nd class.Please help me

class 1(save record)
-----------
public with sharing class saveInputController {
public string positionname{set;get;}
   
   
    public PageReference saveposition() {
    position__c p=new position__c();
     p.name=positionname;
     insert p;
     PageReference posPage = new PageReference('https://c.ap2.visual.force.com/apex/showinput?id=' + p.name);//I didnt covered this in test class .
     posPage.setRedirect(true);
     return posPage;
    }
}
testclass for class one
------------------------------------

@isTest
public class testsaveInputController{

public static testmethod void v1 (){
position__c p= new Position__c(name='maha');
insert p;
position__c p1= new Position__c(name='maha1');
insert p1;
position__c p2= new Position__c(name='maha2');
insert p2;
Test.startTest();
saveInputController sic=new saveInputController ();
PageReference myVfPage =sic.saveposition();
Test.stopTest();
System.assertEquals('maha', myVfPage );
}
}



class2(display as outfield)(I am not knowing how to write testclass for this because of page reference)
--------------------------------------
public with sharing class showinputcontroller {
public List<position__c> p{get;set;}

public showinputcontroller(){
p=[select name from position__c where name like :ApexPages.currentPage().getParameters().get('id') limit 5];
}

}
