deep_merge(other_hash, &block)
Instance Public methods
Returns a new hash with self and other_hash
merged recursively.
1 2 3 4 | h1 = { a: true, b: { c: [1, 2, 3] } }h2 = { a: false, b: { x: [3, 4, 5] } }h1.deep_merge(h2) #=> { a: false, b: { c: [1, 2, 3], x: [3, 4, 5] } } |
Like with Hash#merge in the standard library, a block can be provided to merge values:
1 2 3 4 | h1 = { a: 100, b: 200, c: { c1: 100 } }h2 = { b: 250, c: { c1: 200 } }h1.deep_merge(h2) { |key, this_val, other_val| this_val + other_val }# => { a: 100, b: 450, c: { c1: 300 } } |
