我正在尝试在Rails 4中创建一个应用程序。我很难设置基本关系。
我有用户，个人资料，视觉，个性和模型的模型。资格。
协会是：
User.rb
Profile.rb
belongs_to :user
has_one :personality
accepts_nested_attributes_for :personality
has_many :qualifications
accepts_nested_attributes_for :qualifications, reject_if: :all_blank, allow_destroy: true
has_one :vision
accepts_nested_attributes_for :vision, reject_if: :all_blank, allow_destroy: true
Vision.rb
belongs_to :profile
Personality.rb
belongs_to :profile
Qualifications.rb
belongs_to :profile
控制器是：
用户

从上面可以看出，我已经尝试了各种不同的解决方案，包括使用cocoon gem（我已经用于资格模型）。
没有任何作用。显示在配置文件显示页面上的唯一属性是存储在配置文件表或用户表中的属性。属于配置文件的所有模型都不显示在配置文件中。显示与配置文件具有多态关联的模型。
目前，当我保存并尝试此操作时，本地主机服务器会显示一个名为＆＃39;未经许可的参数：个人资料＆＃39;的错误。我可以看到资格，表单中的条目显示在服务器中，但它们不会出现在配置文件页面上。对于其余每个嵌套属性 - 它们都不会显示在配置文件显示页面上。 rails控制台显示个性的所有属性（其个人资料页面显示的用户的个人资料ID为零）。
在我的个人资料表格中，我根本无法显示愿景表单字段。我想这可能是因为我补充说：
reject_if: :all_blank, allow_destroy: true
接受我的个人资料模型中的视觉接受嵌套属性 - 但是对该部分进行评论并不能改善这种情况。
我之前问过这个问题，但找不到任何帮助。
Rails - Displaying associated attributes - unpermitted parameters
我已经尝试了我在该帖子中列出的每个解决方案（我认为我在帖子末尾附上的网站点文章是我能够找到的最接近相关的内容）。
我没有尝试检查或改变的事情。谁能看到我做错了什么？
当我尝试通过向个人资料表单的个性部分添加条目来更新个人资料时，服务器显示以下输出：

采取MIHAILS建议
我将个性表单字段替换为：
<%= f.simple_fields_for :personality do |ff| %>
<div class="form-inputs">
<%= ff.input :average_day, :label => "What does your day to day work life involve?", as: :text, :input_html => {:rows => 5} %>
<%= ff.input :fantasy_project, :label => "Describe your fantasy project", as: :text, :input_html => {:rows => 5} %>
<%= ff.input :preferred_style, :label => "How do you like to work (distributed teams, on site, easy going about it)?", as: :text, :input_html => {:rows => 5} %>
</div>
<% end %>
当我尝试这个时，个性表单字段不会作为所有
的个人资料表单的一部分呈现采取MIHAILS后续建议
我将配置文件控制器中的构建个性化操作替换为：
@profile.personality = Personality.new
之前是：@ profile.build.personality
当我尝试这个时，我得到了和以前一样的错误 - 我根本看不到个性的表单字段。
采取行动的建议：
如果我采取新行动：
@profile.build_personality
我仍然无法看到人格领域的形式。没有改变先前的尝试
进一步更新
似乎Mihail的第二个建议中的解释与TRH的建议具有相同的效果。目前，我的配置文件控制器有这个新动作：
def new
@profile = Profile.new
@profile.qualifications_build
@profile.build_vision
@profile.build_personality
@profile.addresses_build
authorize @profile
end
它还没有用。
采取MIHAIL＆＃39;下一步建议
def new
@profile = Profile.new
@profile.qualifications_build
@profile.build_vision
@profile.build_personality unless personality
@profile.addresses_build
authorize @profile
end
我仍然无法看到个人资料表单字段。
解决方案：
def new
@profile = Profile.new
@profile.qualifications_build
@profile.build_vision
@profile.build_personality unless @profile.personality
@profile.addresses_build
authorize @profile
end
# GET /profiles/1/edit
def edit
@profile.build_personality unless @profile.personality
end
答案 0 :(得分：3)
问题在于人格领域的局部。如果您仔细查看在更新时提交给服务器的属性，您会发现它们是错误的。
"profile"=>{"profile"=>{"personality"=>{"average_day"=>"sdf"}}
因此，要解决此问题，您需要检查此部分并仅在其中保留嵌套字段块。
<%= f.simple_fields_for :personality do |ff| %>
<div class="form-inputs">
<%= ff.input :average_day, :label => "What does your day to day work life involve?", as: :text, :input_html => {:rows => 5} %>
