Creating ruby constants from strings safely 08/02/2023

Using the .constantize method

 # If the constant does not exist, this will raise a NoMethodError exception
"Foo::Bar".constantize

Safer alternative: Using the .safe_constantize method

 # It returns nil if the constant does not exist
"Foo::Bar".safe_constantize
