Question

我正在尝试使用fields_for为我的用户执行编辑操作。问题是它不会在用户中保存专业版。它不会更新专业属性。

我有2个模型，pro和`user``

用户has_one亲和专业belongs_to用户。

在用户模型中，我放了：accepts_nested_attributes_for :pro, allow_destroy: true

在用户控制器中，我放了：

def user_params
    params.require(:user).permit(:name, :pro, :tos_agreement, :avatar,
                                 :avatar_cache, :is_pro,:email, :password,
                                 :password_confirmation,
                                 pro_attributes: [
                                   :type, :pro_name, :is_pro, :pro_image,
                                   :is_active, :web, :user_id, :about,
                                   :facebook, :twitter, :linkedin, :telephone])
  end

  def edit
    @user = User.friendly.find(params[:id])
  end

  def update
    @user = User.friendly.find(params[:id])
    pro = @user.build_pro
  end

最后，在我的edit.html.erb视图中，我已添加到表单中：

     <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put }) do |f| %>
    <ul class="accordion-submenu">
      <li class="semi_padding">
          <%= f.label :nombre %>
          <%= f.text_field :name, :autofocus => true %>
          <%= f.label :email %>
          <%= f.email_field :email %>
          <%= f.label "Algo sobre tí" %>
          <%= f.text_field :description, placeholder: "Soy una persona amante de la decoración..." %>
          <%= f.label "Lugar" %>
          <%= f.text_field :location , placeholder: "¿De donde eres? Ej: Bilbao"%>
      </li>
    </ul>
  </li>
    <li>
    <a href="javascript:void(0)" class="js-accordion-trigger">
    <i class="icon-switch"> </i> Contraseña</a>
    <ul class="accordion-submenu">
      <li class="semi_padding">
        <%= f.label :contraseña %>
        <%= f.password_field :password, :autocomplete => "off" %>
        <%= f.label "Confirmación de contraseña" %>
        <%= f.password_field :password_confirmation %>
      </li>
    </ul>
  </li>
  <% if @user.has_role :pro %>
   <li>
    <a href="javascript:void(0)" class="js-accordion-trigger">
    <i class="icon-store"> </i> Datos de marca PRO</a>
    <ul class="accordion-submenu">
      <li class="semi_padding">
       <%= fields_for @user.pro do |builder| %>
        <%= builder.label :facebook %>
        <%= builder.text_field :facebook, placeholder: "Facebook URL" %>
        <%= builder.label :twitter %>
        <%= builder.text_field :twitter,  placeholder: "Twitter URL" %>
        <%= builder.label :linkedin %>
        <%= builder.text_field :linkedin,  placeholder: "Linkedin URL"%>
      <% end %>
      </li>
    </ul>
  </li>
  <% end %>

我可以看到params在日志中，但是，它们没有得到保存。有什么建议？谢谢！

Answer 1

试试这个：

pro = @ user.build_pro（params [：pro_attributes]）

Answer 2

尝试更改强params方法，您需要传递id以进行更新

params.require(:user).permit(:id, :name, :pro, :tos_agreement, :avatar,
                                 :avatar_cache, :is_pro,:email, :password,
                                 :password_confirmation,
                                 pro_attributes: [
                                   :user_id, :type, :pro_name, :is_pro, :pro_image,
                                   :is_active, :web, :user_id, :about,
                                   :facebook, :twitter, :linkedin, :telephone])

Fields_for不保存更新数据
