Re: How to add a defaults database to a theme ?

[Fred Kiefer]

Hi Bertrand,

I think you are misreading the compiler warning. This just complains that the 
class that this method is on already has an instance variable with the name 
„defaults“. You should just use a different name for your local variable 
instead. Maybe something like „user_defaults“?

Hope this helps,
Fred
