Ruby Hash check is subset?
contain, hash, ruby, subset
Solution
Since Ruby 2.3 you can also do the following to check if this is a subset
hash = {a: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: 7}
{} <= hash # true
{f: 6, c: 3} <= hash # true
{f: 6, c: 1} <= hash # false
Problem
How can I tell if if a Ruby hash is a subset of (or includes) another hash? For example: ``` hash = {a: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: 7} hash.include_hash?({}) # true hash.include_hash?({f: 6, c: 3}) # true hash.include_hash?({f: 6, c: 1}) # false ```
