我用Rails 3.2.6Rails的嵌套形式插入空
我們有在運作，直到最近（不完全肯定時錯誤發生開始）嵌套形式。現在查詢傳入空值。
輸出示例：

所以你可以看到屬性被髮送。我們的控制器是這樣的。
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

我真的不喜歡這個協會成立，但它是它是什麼。發生了什麼事是嵌套形式
<%= 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 %>
以某種方式傳遞字段和Rails是把在零點。我沒有attr_accessible警告。如果我對文章進行更新，它會保存資產數據。因此，我認爲初始化出了問題，但我不確定是什麼。
TLDR 儘管attr_accessible具有嵌套屬性，Rails並沒有將值傳遞到SQL查詢中。
編輯
的contentTypesController有一些在此之前，我原本以爲是問題的過濾器（他們仍然可我還是搞清楚是如何被使用的話）
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
如果有人能夠指引我走向正確的方向，我會非常高興。我對發生錯誤的地方感到不知所措。 – Micharch54 2012-07-12 17:28:05
任何過濾器之前？ – Renra 2012-07-12 17:37:08
我已編輯帖子以顯示過濾器。這也是我的第一個想法。 – Micharch54 2012-07-12 18:07:09
