Rails 6、Paperclip、S3、s3_direct_upload @attachment.save 在 s3_direct_upload 完成后不保存

[英]Rails 6, Paperclip, S3, s3_direct_upload @attachment.save not saving after the s3_direct_upload completes

問題描述

我已經將一個名為 FilterTrak 的應用程序從舊版本的 Rails v4.2 重寫為 Rails v6，現在除了圖片上傳的一部分外，我的所有工作都可以正常工作。

該應用程序使用 Paperclip、aws-sdk-v1 和 s3_direct_upload。 我之前在使用 s3_direct_upload 時遇到了問題。 我現在遇到的問題是在將文件上傳到 s3 后，它應該保存附件，該附件將從數據庫中給我一個 ID，然后調用應該啟動的輔助進程。

由於未知的原因，@attachment.save 沒有保存，並且因為它沒有保存它沒有回調第二個進程，該進程應該將文件移動到 S3 上的永久位置，然后將該信息保存到數據庫中。 我曾嘗試手動調用第二個進程，但由於附件未保存，因此未生成 ID。 由於我沒有可使用的 ID，因此無法手動或以其他方式調用第二個進程。 我相信我已經解決了控制器和@attachment.save 行的問題。 如果我在那之后立即檢查@attachment.save，我會得到@attachment.save FALSE。 這段代碼目前在舊版本的 Rails 上運行。 因此，我認為由於較新版本的 Rails 中的某些更改，這部分無法正常工作。 我花了超過 2 個星期的時間試圖解決這個問題，但我沒有取得任何進展。 我正在考慮更改應用程序以使用活動存儲，但由於 @attachment.save 是我認為不起作用的部分，我不知道這是否真的有任何好處，因為文件上傳似乎不在問題是據我所知。 因為它實際上確實成功上傳到我的 S3 存儲桶到 /uploads 文件夾中。

這是attachments_controller.rb 文件。

class AttachmentsController < ApplicationController
  load_and_authorize_resource except: [:create]
  skip_authorization_check only: [:create]

  before_action :set_service, only: [:create, :update, :destroy]
  before_action :set_attachment, only: [:update, :destroy]

  def create!
    @attachment = @service.attachments.new(attachment_params)
    @attachment.when = params[:when]
    @attachment.save 
  end

  def update
    respond_to do |format|
      if @attachment.update(attachment_params)
        format.html { redirect_to @attachment, notice: 'Attachment was successfully updated.' }
        format.json { render :show, status: :ok, location: @attachment }
      else
        format.html { render :edit }
        format.json { render json: @attachment.errors, status: :unprocessable_entity }
      end
    end
  end

  def destroy
    @attachment.destroy
    respond_to do |format|
      format.html { redirect_to customer_filter_service_path(@customer, @filter, @service), notice: 'Picture was successfully removed.' }
      format.json { head :no_content }
    end
  end

  private
    def set_service
      @customer = Customer.find(params[:customer_id])
      @filter = @customer.filters.find(params[:filter_id])
      @service = @filter.services.find(params[:service_id])
      #@attachment = Attachment.find(params[:id])
    end

    def set_attachment
      @attachment = Attachment.find(params[:id])
    end

    def attachment_params
      params.require(:attachment).permit(:direct_upload_url)
    end
end

這是attachments.rb模型（將存儲桶名稱更改為mybucket）

在您單擊“選擇文件”按鈕並選擇您的一個或多個文件后，這是上傳過程的開始，並且再次天氣它是 1 個文件或 10 個文件，它們都成功上傳到 S3 到 /uploads 文件夾中。 進度條出現，構建，完成，然后像預期的那樣消失。 第二個過程永遠不會啟動。

這是@service.attachments 的轉儲

這是同一時間點的@attachment：

@attachment: #<Attachment id: nil, service_id: 1137, user_id: nil, direct_upload_url: "https://mybucket.s3.amazonaws.com/uploads/16365640...", upload_file_name: nil, upload_content_type: nil, upload_file_size: nil, upload_updated_at: nil, processed: false, created_at: nil, updated_at: nil, when: nil>

這是同時轉儲的參數：

params#<ActionController::Parameters {"url"=>"https://mybucket.s3.amazonaws.com/uploads%2F1636564061858-fi8lg02378-65280638d6d13515e74449339d1aa926%2FDES+LOGO+%28512x512%29.jpg", "filepath"=>"/uploads%2F1636564061858-fi8lg02378-65280638d6d13515e74449339d1aa926%2FDES+LOGO+%28512x512%29.jpg", "filename"=>"DES LOGO (512x512).jpg", "filesize"=>"86383", "lastModifiedDate"=>"Wed May 24 2017 11:55:08 GMT-0700 (Pacific Daylight Time)", "filetype"=>"image/jpeg", "unique_id"=>"fi8lg02378", "attachment"=>#<ActionController::Parameters {"direct_upload_url"=>"https://mybucket.s3.amazonaws.com/uploads%2F1636564061858-fi8lg02378-65280638d6d13515e74449339d1aa926%2FDES+LOGO+%28512x512%29.jpg"} permitted: true>, "when"=>"before", "controller"=>"attachments", "action"=>"create", "customer_id"=>"419", "filter_id"=>"990", "service_id"=>"1137"} permitted: true>

如果我檢查 @attachment.save 我得到這個：

@attachment.save:false

據我所知，在 after_create 回調中名為 :queue_processing 的第二個進程沒有啟動的原因是因為@attachement.save 沒有保存。 為什么它不保存我不明白。 我嘗試了各種手動方法來嘗試強制保存但它不起作用，我嘗試添加@attachment = Attachment.save，我嘗試添加@attachment = Attachment.create(attachment_params)，我嘗試添加@attachment = Attachment.create(attachment_params[:id]) 都在@attachment.save 之前，無論我做什么它都不會保存，我只是不明白為什么它不會保存。 舊版本 rails 上的相同代碼確實可以保存，並且可以在那時工作。

如果有人有任何想法，我很樂意聽到並且非常感激。 我假設問題來自@attachment.save，但我想也可能是 s3_direct_upload 沒有正確進行回調，但我不知道如何解決該部分的故障。 我在 js 文件中的 console.log 語句中做了，它確實到達了正確的位置，據我所知，它確實觸發了 s3_direct_upload 過程，因為我在每個步驟和每個步驟中都將各種 console.log 條目放入其中我能說的最好。

我還嘗試升級到更高版本的 aws-sdk（版本 3）和 kt-paperclip，它執行完全相同的操作，因此我能說的似乎不是 paperclip 或 aws 的故障。 我什至願意弄清楚如何手動從數據庫中獲取下一個 ID，然后在@attachment.save（我已經嘗試過）之后手動調用 queue_proccessing。 我不能讓它工作的唯一原因是因為@attachment.save 沒有保存所以它不返回一個 ID，沒有 ID 我不能手動調用它。

非常感謝任何幫助。 我什至願意雇用或支付某人的幫助來解決這個問題，因為我很困，需要了解這個問題的答案。 我有第二個應用程序在同一個位置以同樣的方式失敗。 另一個應用程序也是從更舊版本的 Rails v3.2 重寫為當前版本。 這是我唯一無法修復的部分。

如果有人想讓我發布任何其他內容，請告訴我，我將非常樂意發布任何其他任何有用的東西。

謝謝你，斯科特

在@attachment.save 上試試@attachment.valid？ 檢查對象是否有效 如果對象無效，則通過@attachment.errors.full_messages檢查錯誤消息您可以清楚地看到缺少和無效的屬性

這里“@attachment：#<Attachment id：nil，service_id：1137，user_id：nil，direct_upload_url：“https://mybucket.s3.amazonaws.com/uploads/16365640...”，upload_file_name：nil，upload_content_type：nil ,upload_file_size:nil,upload_updated_at:nil,processed:false,created_at:nil,updated_at:nil,when:nil>"你可以看到user_id丟失設置用戶id然后再試我希望在這之后你的問題得到解決
