Custom Settings Update Trigger

Finally getting back into some more development... We had a situation where in order to make the code dynamic it made sense to use Custom Settings. I have never used them before today, there are Hierarchy and List Custom Settings. Hierarchy can only have one set of values per Profile or User, while List can have multiple values for a single Custom Setting.

The problem is that we need a way to dynamically add a 'Level' to a custom object based on the record type of the object. If a new record type is added all we want the sys admin to do is add a new custom setting and have the code do the rest. So long as the new custom setting and the record type have the same name the code will work.

First the code looks to the Custom Setting and pulls all values out of it and stores them in a list. Next we determine the size of the list, then we run a for loop that loops through if statement no more than the size of the list. If it finds that the field called 'Record_Type__c' in our Custom Setting called Level_Setting__c matched the name of the record type of the territory. (I had to use a formula field that just pulls the record name because I could not find a field on the custom object that was the name of the record type.) Finally if it finds a match it sets the custom field on the Custom Setting called Level__c equal to the text field Level__c on the Territory.

So long as the Record Type and the Level in the Custom setting are both in the correct order numerically and the record type names match up, this code working alongside the Custom Setting will work nicely.


trigger BeforeInsertUpdateLevelUpdateTrigger on Territory__c (before insert, before update) {

for(Territory__c t: trigger.new){

List<Level_Setting__c> levelSet = Level_Setting__c.getall().values();
//Pull values from the Custom Setting 'Level_Setting__c'

integer size = levelSet.size();
for(integer i=0; i<size; i++){
                      //Loop through the list of Level_Settings__c to find a match to the record type
if(levelSet[i].Record_Type__c == t.RecordTypeName__c ){
t.Level__c = levelSet[i].Level__c;
}
}
}
}
