Jesus Ferreras Save error: Initial term of field expression must be a concrete SObject: LIST<EventRelation>
I need help. I want to create a batch class to update values from another object. this is my code but it is giving me this error
anyone can help? Thanks.
This is the start and execute section
global Database.Querylocator start(Database.BatchableContext bc){
return Database.getQueryLocator([SELECT ID, Comentarios_Invitados__c,EventRelationId__c,Estado_Invitado__c,fecha_del_evento__c FROM Informe_icex__c where fecha_del_evento__c>=LAST_N_DAYS:1]);
}
global void execute(Database.BatchableContext BC, List<sObject> scope){
// Create a map for the chunk of records passed into method.
Map<ID, Informe_icex__c> iMap = new Map<ID, Informe_icex__c>((List<Informe_icex__c>)scope);
List<EventRelation> eRList = [SELECT Id,response,status FROM EventRelation WHERE Id IN
:iMap.keySet()];
for(Informe_icex__c i : jobMap.values()){
if(!eRList.isEmpty()){
i.Comentarios_Invitados__c = eRList.response;
i.Estado_Invitado__c = eRList.status;
}
}
update iMap;
}
Hello, there are some problems in the code
iMap.keySet() this contains the id of Informe_icex__c object.
But you are fetching EventRelation from that id.
List<EventRelation> eRList = [SELECT Id,response,status FROM EventRelation WHERE Id IN
:iMap.keySet()];
Again you are assigning value from a list directly like
i.Comentarios_Invitados__c = eRList.response;
Either you do eRList.get(0) or use loop to get it covered.
And also before updating do this
List<Informe_icex__c> listToBeUpdated = new List<Informe_icex__c>();
then in loop after assigning do like this
listToBeUpdated.add(i);
Outside loop
if(listToBeUpdated.size()>0){
update listToBeUpdated;
}

Hello souvik9086
I made the changes but have this error 'Save error: Variable does not exist: listToBeUpdated'
List<EventRelation> eRList = [SELECT Id,response,status FROM EventRelation WHERE Id IN
:iMap.keySet()];
for(Informe_icex__c i : jobMap.values()){
List<Informe_icex__c> listToBeUpdated = new List<Informe_icex__c>();
if(!eRList.isEmpty()){
i.Comentarios_Invitados__c = eRList.response;
i.Estado_Invitado__c = eRList.status;
listToBeUpdated.add(i);
}
}
if(listToBeUpdated.size()>0){
update listToBeUpdated; //the error is Save error: Variable does not exist: listToBeUpdated
}
}
I can do, can help
Thanks,
You have to declare the list variable before the for loop like this
List<Informe_icex__c> listToBeUpdated = new List<Informe_icex__c>();

in this case I have this error 'Save error: Initial term of field expression must be a concrete SObject: LIST<EventRelation>' the original error
Map<ID, Informe_icex__c> iMap = new Map<ID, Informe_icex__c>((List<Informe_icex__c>)scope);
List<EventRelation> eRList = [SELECT Id,response,status FROM EventRelation WHERE Id IN
:iMap.keySet()];
List<Informe_icex__c> listToBeUpdated = new List<Informe_icex__c>();
for(Informe_icex__c i : jobMap.values()){
if(!eRList.isEmpty()){
i.Comentarios_Invitados__c = eRList.response;
i.Estado_Invitado__c = eRList.status;
listToBeUpdated.add(i);
}
}
if(listToBeUpdated.size()>0){
update listToBeUpdated;
}
}
I mentioned that in my first post that
"Again you are assigning value from a list directly like
i.Comentarios_Invitados__c = eRList.response;
Either you do eRList.get(0) or use loop to get it covered."
You have to use that one value not the list.

There are several basic mistake in your code.
Map<ID, Informe_icex__c> iMap = new Map<ID, Informe_icex__c>((List<Informe_icex__c>)scope);//In the below query you are comparing EventRelation's Id with Informer_icex__c Id and they will never match and hence this wont return any value
List<EventRelation> eRList = [SELECT Id,response,status FROM EventRelation WHERE Id IN :iMap.keySet()]; List<Informe_icex__c> listToBeUpdated = new List<Informe_icex__c>(); for(Informe_icex__c i : jobMap.values()){ if(!eRList.isEmpty()){//in the below lines : You cannot assign a list to field, where erList is a list and you can access fields of a single object not a list i.Comentarios_Invitados__c = eRList.response; i.Estado_Invitado__c = eRList.status; listToBeUpdated.add(i); } } if(listToBeUpdated.size()>0){ update listToBeUpdated; } }
Hello is true, I saw that the ErList list is empty,
what is the correct syntax, I am beginner in that, can you help me?
List<EventRelation> eRList = [SELECT Id,response,Status,RelationId,EventId,RespondedDate FROM EventRelation WHERE Id IN
:iMap.keySet()];
System.Debug('EventRelation Records 1 : ' + eRList);
Thanks,
anyone can help me with this batch, the problem is that I'm not finding the records of the entity EventRelation to update the records of the entity Informe_icex.
Thanks
Map<ID, Informe_icex__c> iMap = new Map<ID, Informe_icex__c>((List<Informe_icex__c>)scope);
System.Debug('iMap Records : ' + iMap);
List<EventRelation> eRList = [SELECT Id,response,Status,RelationId,EventId,RespondedDate FROM EventRelation WHERE Id IN
:iMap.keySet()];
System.Debug('EventRelation Records 1 : ' + eRList); // the results is empty
List<Informe_icex__c> listToBeUpdated = new List<Informe_icex__c>();
for(Informe_icex__c i : iMap.values()){
System.Debug('EventRelation Records 2 : ' + eRList);
System.Debug('Informe_Icex Records: ' + i);
if(!eRList.isEmpty()){
i.Comentarios_Invitados__c = eRList[0].response;
i.Estado_Invitado__c = eRList[0].status;
listToBeUpdated.add(i);
}
}
if(listToBeUpdated.size()>0){
update listToBeUpdated;
}
Hello Avidec9,
the problem is that I'm not finding the records of the entity EventRelation to update the records of the entity Informe_icex,
I think that my error is the red line, because the result of this list is empty.
