Hi,

      Below is the sample code for trigger to fulfill your requirement.

 

trigger updateManager on Contact (before insert) {
for ( Contact c : trigger.new) {
	if(c.CreatedBy != null)
	{
		Id MAnagerID= [ select id,ManagerId from user where id=: Userinfo.getUserId()][0].Managerid;
		string MAnagerNAme= [ select id,Name from user where id=: MAnagerID][0].Name;
		system.debug('=================' +MAnagerNAme);
		c.Manager__c = MAnagerNAme;
	}
}
}

  Did this answer your question? If not, let me know what didn't work, or if so, please mark it solved.

Hi,

    Sorry, i missed the update command in the sample code:

trigger updateManager on Contact (before insert) {
for ( Contact c : trigger.new) {
if(c.CreatedBy != null)
{
Id MAnagerID= [ select id,ManagerId from user where id=: Userinfo.getUserId()][0].Managerid;
string MAnagerNAme= [ select id,Name from user where id=: MAnagerID][0].Name;
system.debug('=================' +MAnagerNAme);
c.Manager__c = MAnagerNAme;
update c;
}
}
}

Its not updating still. My Manager filed is a look up field and.. I have a question as to Y cant we have ManagerID for Manager__c; Y are we providing ManagerName.

 

 

  Id MAnagerID= [ select id,ManagerId from user where id=: Userinfo.getUserId()].Managerid;
        system.debug('****' +MAnagerId);
 string MAnagerNAme= [ select id,Name from user where id=: MAnagerID].Name;
  system.debug('=================' +MAnagerNAme);
        c.Manager__c = MAnagerID;
        update c;

Hi,

        This is the updated sample code.change the Manager Name to manager id and then it works fine.

 

trigger updateManager on Contact (before insert) {
for ( Contact c : trigger.new) {
if(c.CreatedBy != null)
{
Id MAnagerID= [ select id,ManagerId from user where id=: Userinfo.getUserId()][0].Managerid;
string MAnagerNAme= [ select id,Name from user where id=: MAnagerID][0].Name;
system.debug('=================' +MAnagerNAme);
c.Manager__c = MAnagerID;
update c;
}
}
}

Hi Here is my final code  after modifications 

trigger updateManager on Contact (before insert) {
for ( Contact c : trigger.new) {
if(c.createdby.Name != 'xx' )
{
Id MAnagerID= [ select id,ManagerId from user where id=: Userinfo.getUserId()][0].Managerid;

c.manager__c= MAnagerID;
//update c;
}
}
}

 What I dont get is . It doesnot wok when I give c.createdby!= NULL.   I do not understand why doesnt it takes null.

 

This works fine.

In a before insert trigger, any more than first degree references (lookup fields) will evaluate to null (perhaps http://cloudnow.wordpress.com/2011/04/04/apex-bloopers-why-art-thou-null/ explains it a bit better)

 

so c.CreatedById will not be null, but c.CreateBy.Name will be Null, as that value is not available in the contex just yet.

 

This value will be available in say a before update trigger.

 

Also this trigger isnt buklified, if you intend for it to be used en masse, then here goes

 

trigger updateManager on Contact (before insert) {
Id[] createdByIds = new Id[]{};
for ( Contact c : trigger.new)
createdByIds.add(c.CreatedById);

Map<Id, User> createdMap = new Map<Id,User>([ select id,ManagerId from user where id IN :createdByIds]);

for(Contact c: trigger.new)
{
if(c.createdbyId != null)
c.manager__c= createdMap.get(c.CreatedById).ManagerId;
}
}

}
