Method: Hash#stringify_keys!

Defined in:
lib/core/facets/hash/symbolize_keys.rb

#stringify_keys!(&select) ⇒ Object

Destructively convert all keys to strings. This is the same as Hash#stringify_keys, but modifies the receiver in place and returns it. With a select block, limits conversion to only certain keys.

foo = { :name=>'Gavin', :wife=>:Lisa }
foo.stringify_keys!    #=>  { "name"=>"Gavin", "wife"=>:Lisa }
foo                    #=>  { "name"=>"Gavin", "wife"=>:Lisa }

This method is considered archaic. Use #rekey instead.
