# ActiveRecord::Persistence::ClassMethods

### Public Instance Methods

create(attributes = nil, options = {}, &block) click to toggle source

Creates an object (or multiple objects) and saves it to the database, if validations pass. The resulting object is returned whether the object was saved successfully to the database or not.

The `attributes` parameter can be either be a Hash or an Array of Hashes. These Hashes describe the attributes on the objects that are to be created.

`create` respects mass-assignment security and accepts either `:as` or `:without_protection` options in the `options` parameter.

#### Examples

    # Create a single new object
    User.create(:first_name => 'Jamie')

    # Create a single new object using the :admin mass-assignment security role
    User.create({ :first_name => 'Jamie', :is_admin => true }, :as => :admin)

    # Create a single new object bypassing mass-assignment security
    User.create({ :first_name => 'Jamie', :is_admin => true }, :without_protection => true)

    # Create an Array of new objects
    User.create([{ :first_name => 'Jamie' }, { :first_name => 'Jeremy' }])

    # Create a single object and pass it into a block to set other attributes.
    User.create(:first_name => 'Jamie') do |u|
      u.is_admin = false
    end

    # Creating an Array of new objects using a block, where the block is executed for each object:
    User.create([{ :first_name => 'Jamie' }, { :first_name => 'Jeremy' }]) do |u|
      u.is_admin = false
    end

    # File lib/active_record/persistence.rb, line 40
    def create(attributes = nil, options = {}, &block)
      if attributes.is_a?(Array)
        attributes.collect { |attr| create(attr, options, &block) }
      else
        object = new(attributes, options, &block)
        object.save
        object
      end
    end
