Rails 6, Paperclip, S3, s3_direct_upload @attachment.save s3_direct_upload 完成后不保存
Rails 6, Paperclip, S3, s3_direct_upload @attachment.save not saving after the s3_direct_upload completes
我已经从 Rails v4.2 的旧版本到 Rails v6 重写了一个名为 FilterTrak 的应用程序，除了图片上传的一部分，我现在一切正常。
该应用程序使用 Paperclip、aws-sdk-v1 和 s3_direct_upload。我之前遇到了 s3_direct_upload 的问题，我开始工作了。我现在遇到的问题是，在将文件上传到 s3 之后，它应该保存附件，这会给我一个来自数据库的 ID，然后调用应该启动的辅助进程。
由于未知原因，@attachment.save 没有保存，因为它没有保存，所以没有回调到第二个进程，该进程应该将文件移动到 S3 上的 perm 位置，然后保存该信息进入数据库。我曾尝试手动调用第二个进程，但由于附件未保存，因此未生成 ID。由于我没有可使用的 ID，因此我无法手动或以其他方式调用第二个流程。我相信我已经解决了控制器和 @attachment.save 行的问题。如果我在那之后检查@attachment.save，我会得到@attachment.save FALSE。此代码目前在 Rails 的旧版本上正常工作。所以我假设由于新版本 Rails 中的某些更改，这部分无法正常工作。我花了 2 个多星期的时间试图解决这个问题，但我没有取得任何进展。我正在考虑更改应用程序以使用活动存储，但由于 @attachment.save 是我认为不起作用的部分，我不知道这是否真的有任何好处，因为文件上传似乎没有据我所知是问题所在。因为它确实成功上传到我的 S3 存储桶到 /uploads 文件夹中。
这是 attachments_controller.rb 文件。

如果我检查@attachment.save，我得到这个：
@attachment.save:false
据我所知，在 after_create 回调中调用 :queue_processing 的第二个进程未启动的原因是 @attachement.save 未保存。为什么它不节省我不明白。我已经尝试了各种手动方法来尝试强制保存但它不起作用，我尝试添加@attachment = Attachment.save，我尝试添加@attachment = Attachment.create（attachment_params ), 我尝试在 @attachment.save 之前添加 @attachment = Attachment.create(attachment_params[:id]) 并且无论我做什么它都不会保存，我只是不明白为什么它不会保存。旧版本 rails 上的相同代码确实保存并在那时工作。
如果有人有任何想法，我很想听听，将不胜感激。我假设问题来自 @attachment.save 但我想也可能是 s3_direct_upload 没有正确进行回调，但我不知道如何解决该部分。我在 js 文件中做了 console.log 语句，它确实到达了正确的位置并且它确实触发了 s3_direct_upload 过程，据我所知，因为我放置了各种 console.log 条目每一步都在里面，我能告诉你每一步都在正常工作。
我也尝试升级到更高版本的 aws-sdk（版本 3）和 kt-paperclip，它做同样的事情所以它似乎不是 paperclip 或 aws 的故障我最好可以告诉。我什至想弄清楚如何手动从数据库中获取下一个 ID，然后在 @attachment.save 之后手动调用 queue_proccessing（我曾尝试这样做）。我无法让它工作的唯一原因是因为 @attachment.save 没有保存，所以它没有返回 ID，没有 ID 我不能手动调用它。
非常感谢任何帮助。我什至愿意雇用或支付某人的帮助，因为我非常困惑并且需要理解这个问题的答案。我有第二个应用程序在相同位置以相同方式失败。这个其他应用程序也是从 Rails v3.2 的更旧版本到当前版本的重写。这是我唯一无法修复的部分。
如果有人想让我 post 任何其他事情请告诉我，我会非常乐意 post 任何其他任何人都可以提供帮助的事情。
谢谢，
斯科特
在 @attachment.save
试试@attachment.valid？检查对象是否有效
如果对象无效，则通过 @attachment.errors.full_messages 检查错误消息
您可以清楚地看到缺失和无效的属性
这里
" @attachment: #<附件 id: nil, service_id: 1137, user_id: nil, direct_upload_url: "https://mybucket.s3.amazonaws.com/uploads/16365640...", upload_file_name: 无, upload_content_type: 无, upload_file_size: 无, upload_updated_at: 无, 已处理: false, created_at: 无, updated_at：无，当：无>”
您可以看到 user_id 缺少设置用户 ID 然后重试
我希望在此之后你的问题得到解决
我已经从 Rails v4.2 的旧版本到 Rails v6 重写了一个名为 FilterTrak 的应用程序，除了图片上传的一部分，我现在一切正常。
该应用程序使用 Paperclip、aws-sdk-v1 和 s3_direct_upload。我之前遇到了 s3_direct_upload 的问题，我开始工作了。我现在遇到的问题是，在将文件上传到 s3 之后，它应该保存附件，这会给我一个来自数据库的 ID，然后调用应该启动的辅助进程。
由于未知原因，@attachment.save 没有保存，因为它没有保存，所以没有回调到第二个进程，该进程应该将文件移动到 S3 上的 perm 位置，然后保存该信息进入数据库。我曾尝试手动调用第二个进程，但由于附件未保存，因此未生成 ID。由于我没有可使用的 ID，因此我无法手动或以其他方式调用第二个流程。我相信我已经解决了控制器和 @attachment.save 行的问题。如果我在那之后检查@attachment.save，我会得到@attachment.save FALSE。此代码目前在 Rails 的旧版本上正常工作。所以我假设由于新版本 Rails 中的某些更改，这部分无法正常工作。我花了 2 个多星期的时间试图解决这个问题，但我没有取得任何进展。我正在考虑更改应用程序以使用活动存储，但由于 @attachment.save 是我认为不起作用的部分，我不知道这是否真的有任何好处，因为文件上传似乎没有据我所知是问题所在。因为它确实成功上传到我的 S3 存储桶到 /uploads 文件夹中。

这是同时转储的参数：

如果我检查@attachment.save，我得到这个：
@attachment.save:false
据我所知，在 after_create 回调中调用 :queue_processing 的第二个进程未启动的原因是 @attachement.save 未保存。为什么它不节省我不明白。我已经尝试了各种手动方法来尝试强制保存但它不起作用，我尝试添加@attachment = Attachment.save，我尝试添加@attachment = Attachment.create（attachment_params ), 我尝试在 @attachment.save 之前添加 @attachment = Attachment.create(attachment_params[:id]) 并且无论我做什么它都不会保存，我只是不明白为什么它不会保存。旧版本 rails 上的相同代码确实保存并在那时工作。
如果有人有任何想法，我很想听听，将不胜感激。我假设问题来自 @attachment.save 但我想也可能是 s3_direct_upload 没有正确进行回调，但我不知道如何解决该部分。我在 js 文件中做了 console.log 语句，它确实到达了正确的位置并且它确实触发了 s3_direct_upload 过程，据我所知，因为我放置了各种 console.log 条目每一步都在里面，我能告诉你每一步都在正常工作。
我也尝试升级到更高版本的 aws-sdk（版本 3）和 kt-paperclip，它做同样的事情所以它似乎不是 paperclip 或 aws 的故障我最好可以告诉。我什至想弄清楚如何手动从数据库中获取下一个 ID，然后在 @attachment.save 之后手动调用 queue_proccessing（我曾尝试这样做）。我无法让它工作的唯一原因是因为 @attachment.save 没有保存，所以它没有返回 ID，没有 ID 我不能手动调用它。
非常感谢任何帮助。我什至愿意雇用或支付某人的帮助，因为我非常困惑并且需要理解这个问题的答案。我有第二个应用程序在相同位置以相同方式失败。这个其他应用程序也是从 Rails v3.2 的更旧版本到当前版本的重写。这是我唯一无法修复的部分。
如果有人想让我 post 任何其他事情请告诉我，我会非常乐意 post 任何其他任何人都可以提供帮助的事情。
谢谢， 斯科特
在 @attachment.save 试试@attachment.valid？检查对象是否有效 如果对象无效，则通过 @attachment.errors.full_messages 检查错误消息 您可以清楚地看到缺失和无效的属性
这里 " @attachment: #<附件 id: nil, service_id: 1137, user_id: nil, direct_upload_url: "https://mybucket.s3.amazonaws.com/uploads/16365640...", upload_file_name: 无, upload_content_type: 无, upload_file_size: 无, upload_updated_at: 无, 已处理: false, created_at: 无, updated_at：无，当：无>” 您可以看到 user_id 缺少设置用户 ID 然后重试 我希望在此之后你的问题得到解决
