merge(hash, &block) Instance Public methods This method has the same semantics of update, except it does not modify the receiver but rather returns a new hash with indifferent access with the result of the merge.

merge!(other_hash) Instance Public methods Alias for: update

replace(other_hash) Instance Public methods Replaces the contents of this hash with other_hash. h = { "a" => 100, "b" => 200 } h.replace({ "c" => 300, "d" => 400 }) # => {"c"=>300, "d"=>400}

reverse_merge(other_hash) Instance Public methods Like merge but the other way around: Merges the receiver into the argument and returns a new hash with indifferent access as result: hash = ActiveSupport::HashWithIndifferentAccess.new hash['a'] = nil hash.reverse_merge(a: 0, b: 1) # => {"a"=>nil, "b"=>1}

reverse_merge!(other_hash) Instance Public methods Same semantics as reverse_merge but modifies the receiver in-place.
