狂欢：相对更改图像位置

Question

我的资产存储在Amazon s3存储桶中，但对于开发模式，我已将图像存储在

下

app/assets/images/spree/products/

文件夹。由于spree视图中的url评估为，因此不会在服务器呈现上加载图像    /spree/products/1/small/vanillabreeze00.jpg?1375747478"

我希望将其更改为/assets/spree/products/1/small/vanillabreeze00.jpg?1375747478  因为这就是图像存在的地方。

我正在使用：

gem 'spree', :github=> 'spree/spree', :branch=> '2-0-stable'
gem 'spree_gateway', :git => 'git://github.com/spree/spree_gateway.git', :branch=> '2-0-stable'
gem 'spree_auth_devise', :github => 'spree/spree_auth_devise', :branch=> '2-0-stable'
gem 'spree_variant_options', :git => 'git://github.com/ScienceInc/spree_variant_options.git', :branch => 'spree2'

Answer 1

狂欢图片位置功能由paperclip gem提供。

它在Spree :: Image here：

中配置

https://github.com/spree/spree/blob/v2.0.4/core/app/models/spree/image.rb#L11-12

这两行列出：

1. 网址 - 从网络服务器获取图片的网址
2. 路径 - 存储图像的文件系统路径

您可以使用以下配置值自定义它们：

https://github.com/spree/spree/blob/v2.0.4/core/app/models/spree/image.rb#L23-24

所以在你的情况下，你可以设置：

Spree::Config[:attachment_url] = '/assets/spree/products/:id/:style/:basename.:extension'

话虽如此。我会建议不要这样做。

存储在Rails中/ app下的内容应该受版本控制。由于这些图像可以上传（创建新图像），删除，修改等等。这会改变这些图像，迫使您一直更新存储在版本控制中的图像。

我建议遵循标准的Spree配置，而不是从

移动图像

  

应用程序/资产/图像/礼包/产品/

到

  

公共/礼包/产品

您可以放心地从版本控制系统中忽略public / spree下的所有文件，一切都应该很棒！

以下组合最终为我提供了最新的Spree（2-3稳定版）。将S3.yml占位符替换为您的实际S3凭据。我一起使用了'雾'和'回形针'宝石。
