Rails的：不能大规模指派保护的属性：奖品，optininpartner

Question

我不断收到这个错误，我已经做模型入店的属性：

class Contest < ActiveRecord::Base 
attr_accessible :optinpartners_attributes, :prizes_attributes, :css, :description,  :enddate, :promotion, :rules, :slug, :startdate, :title 


accepts_nested_attributes_for :optinpartners 
accepts_nested_attributes_for :prizes 


    has_many :contest_entries 
    has_many :contestants, :through => :contest_entries 


    has_many :contest_prizes 
    has_many :prizes, :through => :contest_prizes 

    has_many :contest_optins 
    has_many :optinpartners, :through => :contest_optins 

确切的错误是：

Can't mass-assign protected attributes: prize, optininpartner 


app/controllers/contests_controller.rb:49:in `new' 
app/controllers/contests_controller.rb:49:in `create' 

根据我的理解：如果该属性在模型中可访问，这应该不成问题。但是，大规模分配也是一个安全漏洞，所以如何在不牺牲安全性的情况下解决这个问题？

编辑： 由于要求：这是Contest的_form.erb.html文件。而这个片段是奖品和加入项目

<h2> Enter information on prizes </h2> 

<%= f.fields_for :prize do |builder| %> 

<%= builder.label :prize, "Prize" %><br/> 
<%= builder.text_field :prize%><br/> 
<br/> 
<%= builder.label :description, "Description" %> 
<%= builder.text_field :description%> 


<%end%> 
<hr> 

<hr> 
<h2> Enter information on Opt-In Partners </h2> 

<%= f.fields_for :optinpartner do |builder| %> 

<%= builder.label :name, "Name of Partner" %> 
<%= builder.text_field :name%> 

<%end%> 
<hr> 

Answer 1

取而代之的是复数：optinpartners_attributes，：在attr_accessible prizes_attributes，用单数形式 - ：optionpartner_attributes和：prize_attributes。

attr_accessible :optinpartner_attributes, :prize_attributes, :css, :description,  :enddate, :promotion, :rules, :slug, :startdate, :title
