Saraag Generic CSV reader- Dynamic casting
Hi,
I'm trying to create a generic CSV reader that will read from a Blob into list of records. This class would be called from a controller. This is my first draft. Arguments include file, fieldnames which sort of acts as the map and then the object name. I want to be able to detect what the object is and then read the CSV into a list of records of that type. Not sure what I have here would work (since I'm using PUT method on the generic sObject)
public List<sObject> readCSVRecords(Blob fileContent,List<String> fieldNames,String objName){
Schema.SObjectType targetType = Schema.getGlobalDescribe().get(objName);
List<sObject> returnList=new List<sObject>();
if(fileContent!=NULL&fileContent.size()<MAXFILESIZE){ //currently limited to 2MB
fileString=fileContent.toString();
fileLines=fileString.split('\n');
fileLinesSize=fileLines.size();
for(Integer i=1;i<fileLinesSize;i++){ //leave out headings
String[] inputvalues = filelines[i].split(',');
Integer y=0;
sObject rec=targetType.newSObject(objName); //How do I cast this dynamically?
for(String s:fieldNames){
rec.put(s,inputvalues[y]);
y++;
}
returnList[i-1].add(rec);
}
return returnList;
}
else
return NULL;
}// end readCSVRecords
I would appreciate any help
Thank you
Forgot about this post, I figured out the issue. I used newSObject incorrectly. Here is the correct code:
//---Method Name: readCVSRecords
// Arguments: file content as blob,filed names as list, objname as string,recordtypeid or NULL, boolean to indicate load default values on record.
// Return: List of SObjects
// Description: Call this method with a blob, objectname,fieldnames that correspond to the CSV as list, optional recordtypeid and boolean to indicate if default values are to be loaded.
// Note: fieldnames should follow the exact order of values in CSV. You can may be enhance this by reading fieldnames from the file itself (use fieldapi names as column headers)
