node.js - 在 Keystone.js 中显示带有描述的图库图像时出现问题

Question

我是 Keystone.js 和 Mongodb/nodejs 开发的新手，但我已经喜欢它了。

我正在尝试更改 Keystone 中的默认图库行为，以便为图库中的每个图像添加名称和描述，因为“Types.CloudinaryImages”似乎不允许这样做。可在 Image gallery with caption using CloudinaryImage on keystonejs 上找到我添加了一个新的“图像”模型并修改了我的主页(应显示图库的位置)的路线。

检查控制台日志时，查询确实会检索图库并填充图像的链接，但我的代码显示它们时出现问题。

尝试不同的选项后，我找到了一个可行的解决方案。这可能不是最好的，所以如果有人提出任何补充意见，我将不胜感激。

工作解决方案:我只是修改了jade模板来更改图片源url。

//Portfolio section                                                                                                                               
section.grid#portfolio                                                                                                                            
        if galleries.length                                                                                                                       
                each gallery in galleries                                                                                                         

                                  figure.effect-portfolio.wow.fadeInDown(data-wow-duration="1500ms")                                              
                                         img(src="#{gallery.heroImage.image.secure_url}")                                                         

                                         each image in gallery.images

                                           a(href="#{image.image.url}", title=gallery.name, data-lightbox-gallery=gallery.name, data-lightbox-hidpi="#{image.image.url}")                                                                                                                              

        else                                                                                                                                      
                h4.text-muted There are no image galleries yet.

请注意，保留“if gallery.exists”声明不起作用。我不明白为什么......
