Hi,

Let’s say in Model1 I require ‘net/http’, and in Model9 I also require  
‘net/http’ because I forgot it was already required in Mode1, will that  
cause a problem?

Should I redundantly require libs? Should I put require statements in a  
common place? What’s the consensus on that?

Best regards,

Nope. The second require will be ignored (note that ruby just looks at  
the string you pass require - you could force it to load net/http a  
second time by doing require ‘/usr/local/lib/ruby/1.8/net/  
http’ (assuming that is where those files were on disk)).
