Rails Hotwire + Admin Namespace

Question

我有一个运行rails 6.1.3.2的应用程序。我开始迁移到使用hotwire而不是ujs。我的应用程序使用一个管理名称空间来允许用户进行编辑，通过这个创建项目。下面的路线-

resources :event_attachments
namespace :admin do
  resources :event_attachments
end

当通过管理视图对event_attachment进行更新时，turbo_stream不是在处理管理视图中的部分，而是在查看EventAttachmentsController。我不知道它为什么要这么做-任何建议都会很感激。

管理员:EventAttachmentsController-

  def update
    if @event_attachment.update(event_attachment_params)
      respond_to do |format|
        format.turbo_stream do
          render turbo_stream: [
            turbo_stream.update("flash", partial: "shared/flash", locals: { notice: "Event image updated" }),
            turbo_stream.replace(:event_attachments, partial: 'admin/pages/event_attachment', locals: { event_attachment: @event_attachment })
          ]
        end

        format.html do
          redirect_to edit_admin_event_attachment_path(@event_attachment), notice: 'Event image updated'
        end
      end
    else
      render :edit, status: :unprocessable_entity
    end
  end

这是我在admin/event_attachments上的表格样本-

<%= form_for([:admin, event_attachment], :id =>  dom_id(event_attachment)) do |f| %>
  <%= f.text_field :title, :placeholder => "Event image name *" %>
<% end %>

Rails服务器日志(作为测试，我在主event_attachments视图中创建了一个部分)-

这里的问题似乎是表单发送请求到的url中的问题。如果您查看日志，您将看到它说是EventAttachmentsController#update处理，这是因为在您的形式中，URL是错误的。我的想法是，您应该从使用form_for和[]改为使用form_with

<%= form_with(url: admin_event_attachments_path, :id =>  dom_id(event_attachment)) do |f| %>
  <%= f.text_field :title, :placeholder => "Event image name *" %>
<% end %>
