attributes=(new_attributes) public

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). Sensitive attributes can be protected from this form of mass-assignment by using the attr_protected macro. Or you can alternatively specify which attributes can be accessed in with the attr_accessible macro. Then all the attributes not included in that won’t be allowed to be mass-assigned.

Update attributes on mulitple models

Updates attributes on multiple models, saves each if validations pass. 

  def update_multiple
    @items = Item.find(params[:item_ids])
    @items.each do |item|
      item.attributes = params[:item].reject { |k,v| v.blank? }
    end
    if @items.all?(&:valid?)
      @items.each(&:save!)
      flash[:notice] = "Updated items!"
      redirect_to items_path
    else
      flash[:notice] = "Please enter valid data."
      render :action => 'edit_multiple'
    end
  end
