Method: Fusu::Hash::Except#except

Defined in:

lib/fusu/hash/except.rb

#except(hash, *keys) ⇒ Object

Returns a hash that includes everything but the given keys.

hash = { a: true, b: false, c: nil}
Fusu::Hash.except(hash, :c) # => { a: true, b: false}
hash # => { a: true, b: false, c: nil}

This is useful for limiting a set of parameters to everything but a few known toggles:

@person.update(Fusu::Hash.except(params[:person], :admin))

# File 'lib/fusu/hash/except.rb', line 11

def except(hash, *keys)
  except!(hash.dup, *keys)
