Merge a hash with the key/values of a string in ruby
- by LazyJason
Hi there,
I'm trying to merge a hash with the key/values of string in ruby.
i.e.
h = {:day => 4, :month => 8, :year => 2010}
s = "/my/crazy/url/:day/:month/:year"
puts s.interpolate(h)
All I've found is to iterate the keys and replace the values. But I'm not sure if there's a better way doing this? :)
class String
def interpolate(e)
self if e.each{|k, v| self.gsub!(":#{k}", "#{v}")}
end
end
Thanks
