To Class

This gem adds a to_class method to ActiveSupport::Inflector, Symbol, and String that combines the functionality of ActiveSupport’s camelize and constantize methods—it will convert the object in question to Camel case and then try to find a declared constant with the corresponding name. This allows you to easily get a class from its name with one simple method invocation.

:user.to_class       #=> User
'user'.to_class      #=> User
:blog_post.to_class  #=> BlogPost
'blog_post'.to_class #=> BlogPost
