如何解决“无法批量分配受保护的属性:translations_attributes"错误? [英] How to solve the "Can't mass-assign protected attributes: translations_attributes" error?

问题描述

我正在使用Ruby on Rails(3.2.2)， globalize3 (0.2.0)和 batch_translations (0.1.2)ruby-gems.我想解决使用batch_translations ruby​​-gem时产生的以下问题:

I am using Ruby on Rails (3.2.2), globalize3 (0.2.0) and batch_translations (0.1.2) ruby-gems. I would like to solve the following problem generated when using the batch_translations ruby-gem:

ActiveModel::MassAssignmentSecurity::Error in Admin::ArticlesController#update

Can't mass-assign protected attributes: translations_attributes

在我的ROOT_RAILS/Gemfile文件中，我有:

...
gem 'globalize3'
gem 'batch_translations'

在我的ROOT_RAILS/app/models/admin/article.rb文件中，我有:

class Admin::Article < ActiveRecord::Base
  translates :title

  # This is needed to make the batch_translations to work.
  accepts_nested_attributes_for :translations

  ...
end

在我的ROOT_RAILS/app/views/admin/articles/_form.html.erb文件中，我有:

<%= form_for(@admin_article, :url => admin_article_path) do |f| %>
    <%= f.label :title %><br />
    English translation:
    <%= f.text_field :title %>

    Italiano translation:
    <%
      # Note: I am using the '<%= f...' instad of '<% f...' otherwise
      # batch_translations doesn't output the input field in the
      # front-end content.
    %>
    <%= f.globalize_fields_for :it do |g| %>
      <%= g.text_field :title %>
    <% end %>
<% end %>

在我的ROOT_RAILS/app/controllers/admin/articles_controller.html.erb文件中，我有:

class Admin::ArticlesController < ApplicationController

  def update
    @admin_article = Article.find(params[:id])

    respond_to do |format|
      if @admin_article.update_attributes(params[:article])
        format.html { redirect_to admin_article_path(@admin_erticle), notice: 'Article was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: @admin_article.errors, status: :unprocessable_entity }
      end
    end
  end

  ...
end

当我显示编辑表单时，所有作品都有效，但是当我提交该表单时，出现了上面提到的错误. 如何解决以上错误?

更新

我在ROOT_RAILS/app/models/admin/article.rb文件中使用以下代码找到了解决方案:

I found the solution by using the following code in the ROOT_RAILS/app/models/admin/article.rb file:

class Admin::Article < ActiveRecord::Base
  translates :title

  attr_accessible :translations_attributes
  accepts_nested_attributes_for :translations

  ...
end

...但是确定可以访问:translations_attributes吗?

... but making the :translations_attributes accessible is it sure?

推荐答案

自最新版本的rails对其进行修补以来，这将是一个问题.您可以在配置中更改它.参见 http://weblog .rubyonrails.org/2012/3/30/ann-rails-3-2-3-has-been-released/了解详情.

This will be an issue with the newest version of rails since they patched it. You can change it in the config. See http://weblog.rubyonrails.org/2012/3/30/ann-rails-3-2-3-has-been-released/ for details.

我可以确认您的attr_accessible解决方案是正确的.

I can confirm that your attr_accessible solution is correct.
