Instance Method Details

#deep_reject!(call_on_hash = false, &blk) ⇒ Object

Takes nested Hashes: And rejects values that return true from the block:

{a: {b: {c: ""}, d: ""}}.deep_reject! { |k,v| v.blank? }
# => {:a=>{:b=>{}}}

If you want to call the block on Hash-type values after they’ve been iterated thru, pass true as the first argument.
