Method: Hash#stringify_keys

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

#stringify_keys(&select) ⇒ Object

Return a new hash with all keys converted to strings. Converts all keys in the Hash to Strings, returning a new Hash. With a select block, limits conversion to only a certain selection of 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.
