Here's what I'm trying to accomplish... I have a person model and that peron has a home_country. Currently, home_country is an INT in the table. What I want to be able to do is convert the INT into a Country object when I pull it from the db. In order for the HTML helper functions to work, I overloaded the object.inspect method to provide default method functionality. If I called person.home_country it should invoke the inspect and return to me whichever method I define. This works in the script/console however, it does not work when using the helper functions. I #<Country:...>. Couple of questions: Is there a better way to do this? And why do I experience different behavior in the console and the HTML results? Thanks for your help.

Hello Thomas, 2005/11/30, Thomas S. <email@example.com>: > different behavior in the console and the HTML results? The console inspects return values, while ERb uses to_s. That is why you see different results from the console than on the Web. That being said, which helper are you using ? You should be doing something like this: <%= collection_select :person, :home_country_id, Country.find(:all), :id, :name %> See how I am saying the value is coming from home_country_id instead of home_country ? That's because when the values come back, the home_country_id will be updated, and when the object is saved, the DB will contain the right value. If instead you said home_country, then you'd have a problem - you'd try to assign a Fixnum to a Country instance - not good. Hope that helps !

I'll give that a shot and see how it works. I was alos looking for feedback on the approach to make sure I wasn't heading down the wrong path. Thomas
