我正沿着Lynda.com上的Ruby on Rail 3 Essential Training教程進行操作。我在創建活動記錄條目時遇到困難。這是我在控制檯中遇到的錯誤。ActiveModel :: MassAssignmentSecurity ::錯誤:無法批量分配受保護的屬性:
1.9.3p125 :007 > user = User.new(:first_name => "Mike", :last_name => "Jones")
ActiveModel::MassAssignmentSecurity::Error: Can't mass-assign protected attributes: first_name, last_name

from script/rails:6:in `require'
from script/rails:6:in `<main>`
這是我在我的模型:
class User < ActiveRecord::Base
attr_accessible :first_name, :last_name
end
我在做什麼錯。我有導軌3.2.3
謝謝你的工作!沒有意識到這很簡單。 – 2012-04-17 01:16:35
重新加載!在控制檯應該重新加載控制檯,所以你不必重新啓動它 – ejunker 2012-10-03 00:56:16
