ruby-on-rails - Active Storage + rails 不适用于 docker + nginx

问题描述

我在带有 Docker 和 Nginx 的 rails 6 中使用主动存储。我正在通过 rails 控制台上传图像，即

object.images.attach(io: File.open("#{Rails.root}/image_path"), filename: "image.jpg")

上传成功，但文件未存储在指定位置，即Rails.root.join("storage"). 为此，我没有得到图像文件。

我不确定问题出在 Docker、Nginx 还是 ActiveStorage

请帮忙...

解决方案

我相信您的 docker-compose.yml 中存在命名约定问题

services:
  db:
    image: mariadb:10.3.29
    restart: unless-stopped
    volumes:
      - .:/my_app
      - db-volume:/var/lib/mysql

在卷中，由于您已给出文件夹名称my_app，因此为服务my_app服务创建文件，而不是为app服务创建文件。所以.:/my_app应该更改为您的应用程序服务名称，即.:/app. 修改所有卷，它应该可以工作。
