RegistrationsController#create 中的 ActionController::UnknownFormat (Devise)

Question

我正在尝试通过模式窗口（远程：true）进行设计注册，并在发生某些验证错误时在后端完成所有操作并通过呈现 javascript。到目前为止，我在路上，我的验证消息似乎工作得很好，但是直到我尝试上传图像时，我才得到未知格式错误页面。我已经尝试了一些东西，但由于我对 RoR 很陌生，我的想法走到了尽头。下面是我的registration_controller、模态视图和屏幕截图。

我还没有成功注册对象，所以代码在这一点上可能包含一些问题，但现在描述的问题阻碍了我继续前进。

我将非常感谢您对此提供的任何帮助。 谢谢你，米罗斯拉夫。

当我不上传任何图像时，正确渲染 create.js.erb 并显示错误消息

当我尝试使用回形针上传图片时出现错误页面

Answer 1

文件上传不适用于远程表单。您应该使用其他方式上传文件。

例如；

• https://github.com/JangoSteve/remotipart
• https://github.com/tors/jquery-fileupload-rails

我的建议是使用 remotipart。

Answer 2

如上所示 http://www.mehmet.pw/category/ruby-on-rails/

只需更改registration_path(resource_name)，取出resource_name，使其不查找resource.model，只查找resource...

IT 使用此代码为我工作（修复了相同的错误）：

    <h2>Sign up</h2>
<%= devise_error_messages! %>
<div class="container">
  <%= form_for(resource, as: resource_name, url: user_registration_path, format: :json) do |f| %>
    <form class="form-horizontal">

      <div class="form-group">
        <%= f.label :first_name %>
        <%= f.text_field :first_name, class: 'form-control' %>
      </div>

      <div class="form-group">
        <%= f.label :last_name %>
        <%= f.text_field :last_name, class: 'form-control' %>
      </div>

      <div class="form-group">
        <%= f.label :phone %>
        <%= f.telephone_field :phone, class: 'form-control' %>
      </div>

      <div class="form-group">
        <%= f.label :email %>
        <%= f.email_field :email, class: 'form-control' %>
      </div>


      <div class="form-group">
        <% if @minimum_password_length %>
          <em>(<%= @minimum_password_length %> characters minimum)</em>
        <% end %>
        <%= f.label :password %>
        <%= f.password_field :password, class: 'form-control' %>
      </div>

      <div class="form-group">
        <%= f.label :password_confirmation %>
        <%= f.password_field :password_confirmation, class: 'form-control' %>
      </div>


      <div class="actions">
        <%= f.submit "Create", class:"btn btn-primary btn-lg"%>
      </div>

    </form>
<% end %>
<div class="container-fluid">
  <%= render "devise/shared/links" %>
