problem with trigger ??

my code is :

trigger createUser on Student__c (after insert) {
Profile p = [select id from Profile where name='Standard Platform'];
for(Student__c stud: Trigger.new)
{
User u = new User(alias = 'student', email=stud.Email_ID__c, emailencodingkey='UTF-8', firstName=stud.First_Name__c, lastname=stud.Last_Name__c, languagelocalekey='en_US', localesidkey='en_US', profileid = p.id, timezonesidkey='Europe/London', username=stud.Enrollment_No__c+'@user.com');
insert u;
stud.User__c=u.ID;
}
}

kiranmutturukiranmutturu
try this

trigger createUser on Student__c (after insert) {
Profile p = [select id from Profile where name='Standard Platform' limit 1];
if(p != null){
for(Student__c stud: Trigger.new)
{
User u = new User(alias = 'student', email=stud.Email_ID__c, emailencodingkey='UTF-8', firstName=stud.First_Name__c, lastname=stud.Last_Name__c, languagelocalekey='en_US', localesidkey='en_US', profileid = p.id, timezonesidkey='Europe/London', username=stud.Enrollment_No__c+'@user.com');
insert u;//remove this and add to a list and insert the same after the loop
stud.User__c=u.ID;
}
}
}

Profile p = [select id from Profile where name='Standard Platform'];

Please check if the above query gives you any records..
AmitSahuAmitSahu
Use : "Standard User" for your query.. might work if you dont have any Standard Platform profile.

now i have updated the code

trigger createUser on Student__c (after insert) {
Profile p = [select id from Profile where name='Student'];
for(Student__c stud: Trigger.new)
{
User u = new User(alias = 'student', CommunityNickname=stud.Enrollment_No__c,email=stud.Email_ID__c, emailencodingkey='UTF-8', firstName=stud.First_Name__c, lastname=stud.Last_Name__c, languagelocalekey='en_US', localesidkey='en_US', profileid = p.id, timezonesidkey='Europe/London', username=stud.Enrollment_No__c+'@abcinstitute.com');
insert u;
System.resetPassword(u.Id, true);
stud.User__c=u.id;
update stud;
}
}

 

 

and error is

Error: Invalid Data. Review all error messages below to correct your data. Apex trigger createUser caused an unexpected exception, contact your administrator: createUser: execution of AfterInsert caused by: System.FinalException: Record is read-only: Trigger.createUser: line 8, column 1

Remove the update command
viv1viv1

but i want to assign that user to student...

student is lookup to user !!
AmitSahuAmitSahu
You cannot update the same record in the after trigger. You can use a method in class with future annotations.

Hi Viv,

 

Try below code :-

 

trigger createUser on Student__c (before insert) {
Profile p = [select id from Profile where name='Student'];
for(Student__c stud: Trigger.new)
{
User u = new User(alias = 'student', CommunityNickname=stud.Enrollment_No__c,email=stud.Email_ID__c, emailencodingkey='UTF-8', firstName=stud.First_Name__c, lastname=stud.Last_Name__c, languagelocalekey='en_US', localesidkey='en_US', profileid = p.id, timezonesidkey='Europe/London', username=stud.Enrollment_No__c+'@abcinstitute.com');
insert u;
System.resetPassword(u.Id, true);
stud.User__c=u.id;

}
}
