Rails - Mar 2006 - Re: Displaying related tables in forms.. probably an easy qu

Steve - 

That was the issue.. It seems obvious now, but I needed to reference 

Property.PropertType.name instead of property.propertytype.name

Thanks!!

The fact that you named property_type the way you did with an underscore

makes it especially important that you understand how Rails deals with 
names. I''m not 100% sure, but try referencing property.property_type, 
with the underscore. Rails will know it as PropertyType and 
property_type depending on the context, but not as propertytype.
