How to create a variable name from the value of a string in Ruby on Rails?
This instance_variable_set("#{foo}", "cornholio") needs to read instance_variable_set("@#{foo}", "cornholio")

I was looking for the answer for the same question but with an other thought. Because other people might ending up here looking for my answer here my question and solution:

def some_function(key, interpolation_var, value) t(key, :#{interpolation_var} => value)end
