module ActiveSupport::Inflector

"business".classify # => "Busines"
Singular names are not handled correctly:

"posts".classify # => "Post"
"egg_and_hams".classify # => "EggAndHam"
Examples:

follow +classify+ with +constantize+.)
Note that this returns a string and not a Class. (To convert to an actual class
Create a class name from a plural table name like Rails does for table names to models.

def classify(table_name)
  # strip out any leading schema name
  camelize(singularize(table_name.to_s.sub(/.*\./, '')))
end
