Instance Method Summary

• #deep_merge(other_hash, &block) ⇒ Object

  Source: ActiveSupport - https://github.com/rails/rails/blob/b2eb1d1c55a59fee1e6c4cba7030d8ceb524267c/activesupport/lib/active_support/core_ext/hash/deep_merge.rb Returns a new hash with self and other_hash merged recursively.

• #deep_merge!(other_hash, &block) ⇒ Object

Instance Method Details

#deep_merge(other_hash, &block) ⇒ Object

Source: ActiveSupport

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:

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 } }

#deep_merge!(other_hash, &block) ⇒ Object
