Convert A Symbol To A Constant
If you have a symbol and need to convert it to a constant, perhaps because of some metaprogramming induced by a polymorphic solution, then you may start off on an approach like the following. In fact, I've seen a number of StackOverflow solutions like this.
That is great for one-word constant names, but what about multi-word constants like OpenStruct
. This approach will not work for the symbol :open_struct
. We need a more general solution.
The key is to ditch #capitalize and instead use another ActiveSupport method,
#classify`.
