Rails: Remove Blank Values from Collections

Copy['foo', nil].compact
# => ['foo']

# You can use the splat operator to ignore nil values when constructing an array
['foo', *nil]
# => ['foo']

Copyarray = [1, "", nil, 2, " ", [], {}, false, true]

# Any Rails version
array.reject(&:blank?)
# => [1, 2, true]

# Since Rails 6.1+
array.compact_blank
# => [1, 2, true]

Copyhash = { a: 1, b: "", c: nil, d: 2, e: " ", f: [], g: {}, h: false, i: true }

# Any Rails version
hash.reject { |key, value| value.blank? }
# => { a: 1, d: 2, i: true }

# Since Rails 6.1+
hash.compact_blank
# => { a: 1, d: 2, i: true }
