Rails設計fields_for不工作

我正在使用Devise，但我認爲這不是很重要。Rails設計fields_for不工作

我根本沒有看到fields_for被創建。

這些都是我的文件：

new.html.erb

<%= form_for(resource, :as => resource_name, html: { id: 'registration_form', class: '' }, :url => registration_path(resource_name)) do |f| %> 

    <!-- Error messages --> 
    <%= devise_error_messages! %> 

    <%= render 'new_user_fields', f: f %> 

    <!-- Fields for user-information --> 
    <%= f.fields_for :user_info do |f| %> 

     <%= render 'shared/user_info_fields_for_sign_up', f: f, resource: resource %> 

    <% end %> 

    <!-- Fields for driver-information --> 
    <%= f.fields_for :driver do |f| %> 

     <%= render 'shared/driver_fields_for_sign_up', f: f, resource: resource %> 

    <% end unless resource.driver.nil? %> 

    <!-- Submit button --> 
    <%= f.submit "Sign up", class: "" %> 

<% end %>

共享/ _user_info_fields_for_sign_up.html.erb

<%= f.label t :label_gender %> 
<%= f.collection_select :gender_id, Gender.all, :id, :type, class: '' %> 

<%= f.label t :label_first_name %> 
<%= f.text_field :first_name, class: "" %> 

<%= f.label t :label_last_name %> 
<%= f.text_field :last_name, class: "" %> 

<%= f.label t :label_year_of_birth %> 
<%= f.text_field :year_of_birth, class: "" %> 

<%= f.label t :label_country %> 
<%= f.select :country_alpha2, options_for_select: { Country.all }, class: '' %> 

<%= f.label t :label_city %> 
<%= f.text_field :city, class: "" %> 

<%= f.fields_for :languageskills do |f| %> 

    <%= render 'shared/languageskill_fields', f: f %> 

<% end unless resource.user_info.languageskills.empty?%> 

<%= link_to_add_fields t :label_add_language, f, :languageskills %> 

<%= f.label t :label_interests %> 
<%= f.text_field :interests, class: "" %> 

<%= f.label t :label_about %> 
<%= f.text_field :about, class: "" %>

RegistratiosController.rb

def new 
    super 
    resource.build_user_info 
    resource.user_info.languageskills.build 
    if params[:is_driver].to_i == 1 
     resource.build_driver 
    end 
    Rails.logger.debug(resource.build_user_info.inspect) 
end

的_new_user_fields.html.erb被裝載沒有任何問題。我已將所有可能的符號插入application_controller.rb中的設計輸入參數。雖然這並不重要，對吧？

您能否指點我正確的方向？我沒有看到我的錯誤：S

剛剛找到了錯誤的來源，並會爲它打開一個新帖子。

在我的控制，我可以不叫

resource.build_nested_model

。但是當我在視圖中調用它時，它就可以工作。當它傳遞給視圖時，嵌套模型似乎不會保存到資源中。
