#deep_merge from rails
activesupport/lib/active_support/core_ext/hash/deep_merge.rb Returns a new
hash with self
and other_hash
merged recursively.
h1 = {:x => {:y => [4,5,6]}, :z => [7,8,9]} h2 = {:x => {:y => [7,8,9]}, :z => "xyz"} h1.deep_merge(h2) #=> { :x => {:y => [7, 8, 9]}, :z => "xyz" } h2.deep_merge(h1) #=> { :x => {:y => [4, 5, 6]}, :z => [7, 8, 9] }

Same as deep_merge
, but modifies self
.
# File lib/grape/util/deep_merge.rb, line 16 def deep_merge!(other_hash) other_hash.each_pair do |k,v| tv = self[k] self[k] = tv.is_a?(Hash) && v.is_a?(Hash) ? tv.deep_merge(v) : v end self end
