Question

我有两个模型，服务和照片。在服务模型下，belongs_to：user和has_many：photos和has_many_attached：images。

在照片模型属下属于：service

在“照片”查看器下，我试图显示与每个服务关联的图像。

当我尝试删除图像时，出现ID错误的找不到图像。

查看器如下所示：

<% if @service.images.attached? %>
<br/><br/>

<div class="row">
  <% @service.images.each do |image| %>
    <div class="col-md-4">
      <div class="panel panel-default">
        <div class="panel-heading preview">
          <%= image_tag image %>
        </div>
        <div class="panel-body">
          <span class="pull-right">
            <%= link_to service_photo_path(@photos, image), remote: true, method: 'delete', data: {confirm: "Are you sure?"} do %>
              <i class="fa fa-trash-o" aria-hidden="true"></i>
            <% end %>
          </span>
        </div>
      </div>
    </div>
  <% end %>
</div>
<% end %>

照片控制器如下所示：

class PhotosController < ApplicationController

  def create
    @service = Service.find(params[:service_id])

    if params[:images]
      params[:images].each do |img|
        @service.photos.create(image: img)
    end

    @photos = @service.photos
    redirect_back(fallback_location: request.referer, notice: "Saved...")
  end
end

  def destroy
    @photo = Photo.find(params[:_id])
    service = @photo.service

    @photo.destroy
    @photos = Photo.where(service_id: service_id)

    respond_to :js
  end
end

路线：

service_photos POST /services/:service_id/photos(.:format)photos#create 
service_photo DELETE /services/:service_id/photos/:id(.:format) photos#destroy

Answer 1

替换

@photo = Photo.find(params[:_id])

具有：

@photo = Photo.find(params[:id])

我认为您有错字！ id不是_id

此外，在您看来，请替换：

service_photo_path(@photos, image)

具有：

service_photo_path(@service, photo)

Rails：ActiveRecord :: RecordNotFound在没有ID的情况下找不到照片
