活動存儲導軌保存 blob 和附件數據，但存儲中沒有文件

Question

我正在使用 spree 開發在線商店應用程序。 用戶希望在購物車表單中上傳文件圖像（當然如果不進行下一步，數據將在幾個小時內自動刪除）。 它將為一個選定的變體提供一個附件。 所以因為它使用主動存儲，我必須在 line_item.rb 中聲明has_one_attached:user_file_attachment line_item.rb 。 在add_item.rb里面我正在使用這些代碼

if line_item.nil?
    opts = ::Spree::PermittedAttributes.line_item_attributes.flatten.each_with_object({}) do |attribute, result|
    result[attribute] = options[attribute]
    end.merge(currency: order.currency).delete_if { |_key, value| value.nil? }

    line_item = order.line_items.new(quantity: quantity,
                                           variant: variant,
                                           options: opts)
else
    line_item.quantity += quantity.to_i
end

# here where i place the code to attach the file. I'm using dummy method first.
line_item.user_file_attachment.attach(
            io: File.open('D:\SamplePic\Sample.jpg'),
            content_type: 'image/jpeg',
            filename: 'file_' + Time.zone.now.to_s + '.jpg'
)

它創建[active_storage_blobs]數據和[active_storage_attachments]數據。 但如果我檢查存儲內部，則沒有創建任何內容。

但。 如果我使用order而不是line_item ，它會在存儲中創建數據 blob、附件和文件。

# here where i place the code to attach the file. I'm using dummy method first.
order.user_file_attachment.attach(
            io: File.open('D:\SamplePic\Sample.jpg'),
            content_type: 'image/jpeg',
            filename: 'file_' + Time.zone.now.to_s + '.jpg'
)

如果我檢查order.user_file_attachment.attached? 和line_item.user_file_attachment.attached? 兩者都是返回 true。 但是我在控制台中看到，命令一個有語句Disk Storage (9.3ms) Uploaded file to key....

但是如果我使用line_item，它不會有Disk Storage (9.3ms) Uploaded file to key...

順便說一句，如果我錯了，請糾正我。 我還是新手使用 Spree，還在學習結構。

Answer 1

已經找到方法了。 但我不知道有沒有更好的方法。 隨意評論我的錯誤。 ;)。

我查看了 output 以及我可以做出什么可能性，我發現：我無法將這些代碼放入add_item.rb甚至為此文件中的 function 創建另一個函數/過程。 然后，我注意到只有第一次出現問題，第二次提交時，代碼按預期工作。

因此，在add_item.rb中，我在add_item過程中的result之后將它放在cart_controller.rb中。

def add_item
    spree_authorize! :update, spree_current_order, order_token
    spree_authorize! :show, @variant
    result = add_item_service.call(
        order: spree_current_order,
        variant: @variant,
        quantity: params[:quantity],
        options: params[:options]
    )

    # result.value = its line_item obj

    # here where i place the code to attach the file. I'm using dummy method first.
    result.value.user_file_attachment.attach(
        io: File.open('D:\SamplePic\Sample.jpg'),
        content_type: 'image/jpeg',
        filename: 'file_' + Time.zone.now.to_s + '.jpg'
    )

    render_order(result)
end
