Set value if value is not nil Ruby syntax

Is there a nicer way of doing the following in Ruby?:

user.some_property = something if !something.nil?

So, set user.some_property to the value of something if something is not nil. I need to make that check or Rails throws an error.

Thanks

I'm sorry, but I can't see why:

user.some_property = something unless something.nil?

is preferable to:

user.some_property = something if something

Unless you want some_property to be set as false when something = false rather than nil.

I think the obvious choice is 

user.some_property = something unless something.nil?

But if you do this, you need to think about the consequences of user.some_property potentially being nil. A good way to handle this might be a default value for some_property on initialization
