## I am using a YAML file for my app config, loading it :

## raw\_config = File.read(RAILS\_ROOT + “/config/app\_config.yml”) APP\_CONFIG = YAML.load(raw\_config)[RAILS\_ENV].symbolize\_keys

It’s running well as long as I use alpha keys

development:  
seve:  
api\_token: e09cba8653489749388797926512bb75

then APP\_CONFIG[:seve][“api\_token”] gives me  
e09cba8653489749388797926512bb75

BUT I need to use a ‘numeric’ project\_id key , like 123456 rather  
than seve, and writing

development:  
123456:  
api\_token: e09cba8653489749388797926512bb7

gives me a syntax error, unexpected tINTEGER (which I can  
understand…)

how can I user a numeric key ?

thanks fyh
