使用 Carrierwave 和 Kaminari 进行图像分页

我正在尝试使用 Kaminari gem 对一系列照片进行分页。这些图像正在 Dog 模型的 show 动作中显示，并且照片已使用 CarrierWave 上传到名为 DogPhoto 的单独模型。 DogPhoto属于Dog，Dog有很多DogPhoto。

Dog 控制器的显示操作如下所示（@dog 在过滤器之前加载）：

def show
  @dog_photos = @dog.dog_photos.page(params[:page]).per(1)
end

并且显示视图如下所示：

<div id="dog_photos">
  <% if @dog_photos.count > 0 %>
    <% @dog_photos.each do |dog_photo| %>
      <%= image_tag dog_photo.photo_url %>
    <% end %>
    <%= paginate @dog_photos %>
  <% else %>
    <%= image_tag("dog-with-no-photo.png", :border => false) %>
  <% end %>
</div>

加载页面时，将显示正确数量的照片的分页链接（每张照片一页）。但是，仅显示第一张照片。当用户单击“2”时，它会显示dog-with-no-photo.png 后备图像。

I'm attempting to paginate a series of photos using the Kaminari gem. The images are being displayed in the Dog model's show action, and the photos have been uploaded using CarrierWave to a separate model called DogPhoto. DogPhoto belongs to Dog, and Dog has many DogPhotos.

The Dog controller's show action looks like this (@dog is loaded in a before filter):

def show
  @dog_photos = @dog.dog_photos.page(params[:page]).per(1)
end

And the show view looks like this:

<div id="dog_photos">
  <% if @dog_photos.count > 0 %>
    <% @dog_photos.each do |dog_photo| %>
      <%= image_tag dog_photo.photo_url %>
    <% end %>
    <%= paginate @dog_photos %>
  <% else %>
    <%= image_tag("dog-with-no-photo.png", :border => false) %>
  <% end %>
</div>

When the page is loaded, the pagination links are displayed for the correct number of photos (one page per photo). However, only the first photo is displayed. When the user clicks on "2" it instead shows the dog-with-no-photo.png fallback image.
