instance method `attributes=`

Ruby on Rails 3.1.12

Since v2.2.3 Last seen in v3.1.12

Available in: v2.2.3 v2.3.18 v3.0.20 v3.1.12

Compare with:

attributes=(new_attributes, guard_protected_attributes = nil)

Allows you to set all the attributes at once by passing in a hash with keys matching the attribute names (which again matches the column names).

If any attributes are protected by either attr_protected or attr_accessible then only settable attributes will be assigned.

The guard_protected_attributes argument is now deprecated, use the assign_attributes method if you want to bypass mass-assignment security.

class User < ActiveRecord::Base
  attr_protected :is_admin
end

user = User.new
user.attributes = { :username => 'Phusion', :is_admin => true }
user.username   # => "Phusion"
user.is_admin?  # => false

Parameters

new_attributes req
guard_protected_attributes opt = nil
