This only saves the @person but not the @address. Shouldn’t it save  
both?

```
 @person = Person.new(params[:person])
 @address = Address.new(params[:address])
 @person.address << @address
 @person.save

```

here is what I have:

class Person \< ActiveRecord::Base  
has\_many :addressables  
has\_many :addresses, :through =\> :addressables  
end

class Address \< ActiveRecord::Base  
has\_many :addressables  
has\_many :people, :through =\> :addressables  
end

class Addressable \< ActiveRecord::Base  
belongs\_to :address  
belongs\_to :person  
end

Any help would be appreciated,  
Thanks  
Serge

Hi Folks,

I just upgraded rails from 1.0.0 to 1.1.2. Suddenly, some of my “if  
conditions” stopped working as expected. It seems as though  
Rails/ActiveRecord now treats tinyint(1) columns as boolean instead of  
integers (like v1.0.0).

I was just wondering if anybody else has experienced similar behavior?  
If  
so, is there a quick work-around that doesn’t involve me doing a search  
and  
replace and retesting my entire app?

TIA!

No, at present you have to explicitly create the Addressable object.

You may be better of using a has\_and\_belongs\_to\_many association,  
since your Person\<-\>Address association has no accessory attributes.
