我在Rails 3.2.6中
我们有一个直到最近才运行的嵌套表单（当错误开始发生时并不完全确定）。现在查询传入空值。
示例输出：

因此您可以看到正在发送的属性。我们的控制器看起来像这样。
def new
@article = Article.new
@asset = @article.build_asset
end
def create
@article = Article.new(params[:article])
if @article.save
flash[:notice] = 'Article was successfully created.'
redirect_to @article
else
render :action => "new"
end
end

我真的不喜欢这种关联设置但它就是这样。发生的事情是嵌套表格
<%= f.fields_for :asset do |asset| %>
<fieldset class="span8">
<legend>Asset Description</legend>
<div id='a_title'>
<%= asset.label :name, "Title <span class='req'>*</span>".html_safe %>
<%= asset.text_field :name, :class => 'asset_textarea counter', "data-max" => 255 %>
<br/><span></span>
</div>
<div id='a_desc'>
<%= asset.label :short_desc, "Teaser<span class='req'>*</span>".html_safe %>
<%= asset.text_area :short_desc, :class => "span7 asset_textarea counter", "data-max" => 255, :rows => 7 %>
<br/><span></span>
</div>
</fieldset>
<% end %>
以某种方式传递字段并且Rails将空值放入。我没有attr_accessible警告。如果我对文章进行更新，它将保存资产数据。因此，我认为初始化出了问题，但我不确定是什么。
TLDR 尽管attr_accessible具有嵌套属性，但Rails没有将值传递给sql查询。
修改
contentTypesController有一些我最初认为是问题的过滤器（它们仍然可能是我仍然在弄清楚它们是如何被使用的）
class ContentTypesController < ApplicationController
before_filter :clean_syndication_partners, :only => [:update]
before_filter :setup_existing_content_instance_variable, :except => [:index, :new, :create, :sort, :update_json, :vid_search, :search_library]
#before_filter :setup_new_content_instance_variable, :only => [:new, :create]
before_filter :get_sections
before_filter :get_sites
def clean_syndication_partners
@asset = Asset.find(params[:id], :include => :content)
@asset.syndication_partners = []
end
def get_sites
@sites_all = Site.all(:include => :sections)
end
def get_sections
@sections = Section.all(:include => :site)
end
def setup_existing_content_instance_variable
@asset = Asset.find(params[:id], :include => :content) if @asset.nil?
instance_variable_set("@#{@asset.content.class.name.underscore}", @asset.content)
end
# def setup_new_content_instance_variable
# pub_keyword = false
# current_class = self.controller_name.singularize
# @content_type = current_class.downcase
# if params[current_class]
# cur_content= current_class.camelize.constantize.new(params[current_class])
# #cur_content.asset = Asset.update_attributes(params[current_class][:asset_attributes])
# else
# cur_content= current_class.camelize.constantize.new
# #cur_content.asset=Asset.new
# end
# #cur_content.asset.creator=current_user
# #instance_variable_set(:@asset, cur_content.asset)
# instance_variable_set("@#{current_class}", cur_content)
# end
end
答案 0 :(得分：0)
您忘记将其添加到文章模型中：
accepts_nested_attributes_for :asset, allow_destroy: true
答案 1 :(得分：0)
该问题最终导致从3.2.5升级到3.2.6。我认为这是由于我们使用类继承只是为了共享资产关系。我们回滚了，我们将在未来重新检查这段关系。
