I have a question on  
“ActiveRecord::Associations::AssociationProxy.set\_belongs\_to\_association\_for”  
it is a protected method.

```
    def set_belongs_to_association_for(record)
      if @reflection.options[:as]
        record["#{@reflection.options[:as]}_id"] = @owner.id

```

unless @owner.new\_record?  
record["#{@reflection.options[:as]}\_type"] =  
@owner.class.base\_class.name.to\_s  
else  
record[@reflection.primary\_key\_name] = @owner.id unless  
@owner.new\_record?  
end  
end

I was wondering why class.base\_name was used for the record type and  
not class.name?
