How to create a variable name from the value of a string in Ruby on Rails? -

-

i want create instance variable in controller used in view:

foo = "bar" instance_variable_set("#{foo}", "cornholio")

in view, use @bar that:

@bar => "cornholio"

this generates error: 'bar' not allowed instance variable name

working in rails 3.1

this instance_variable_set("#{foo}", "cornholio") needs read instance_variable_set("@#{foo}", "cornholio")

based on this post. tried in irb ruby 1.93; post 2009.
