- What's this?
except(*keys)
public
Returns a hash that includes everything except given keys.
hash = { a: true, b: false, c: nil } hash.except(:c) # => { a: true, b: false } hash.except(:a, :b) # => { c: nil } 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(params[:person].except(:admin))

Passing an array of keys to exclude.
Use the “*” before passing the array in. For example:
PARAMS_TO_SCRUB = [ :created_at, :updated, :id, :format ] params.except!( *PARAMS_TO_SCRUB )
