2009年8月27日 · result = ERB.new(template).result(namespace.instance_eval { binding }) #=> Name: Joan Maragall. The code above is simple enough but has (at least) two problems: 1) Since it relies on OpenStruct, an access to a non-existing variable returns nil while you'd probably prefer that it failed noisily. 2) binding is called within a block, that's it, in ...
