我有一个很简单的问题:
用户模式:class User < ActiveRecord::Base
devise :database_authenticatable,
:recoverable, :rememberable, :trackable, :validatable
attr_accessible :id, :email, :password, :password_confirmation, :remember_me,
:firstname, :lastname, :mobile_phone, :user_type, :department_id, :department_attributes
belongs_to :department
accepts_nested_attributes_for :department, :allow_destroy => false
部门模型:
class Department < ActiveRecord::Base
has_many :users
accepts_nested_attributes_for :users, :allow_destroy => true
我创建了一个表单,可以使用simple_form:
从现有用户中选择我的部门成员<%= simple_form_for @department, :validate => true do |form| %>
<%= form.error_messages %>
<%= form.association :users, :prompt => 'assign a user', :label => 'User'%>
<%= form.button :submit %>
<% end %>
然后我(尝试)通过部门控制器更新我的用户:
def update
@department = Department.find(params[:id])
respond_to do |format|
if @department.update_attributes(params[:department])
...
生成以下错误:
WARNING: Can't mass-assign protected attributes: user_ids
我的猜测是一些设计设置产生了这个错误,但我不知道是哪些。
你能帮忙吗?谢谢!
将attr_accessible :user_ids
添加到您的Department模型中。
