从 Django（本地 Windows ENV）上传文件到谷歌云存储时遇到问题答案

【问题标题】：Having trouble uploading file to Google Cloud Storage from Django(Local Windows ENV从 Django（本地 Windows ENV）上传文件到谷歌云存储时遇到问题

【问题描述】：

我目前正在开发一个网络应用程序，该应用程序将使用 Google Cloud Storage 上传用户文档。然而，我遇到了障碍。当我尝试继续上传时，我不断收到[Errno 2] No such file or directory: 'Marty McFly-Paycheck-06_ConditionalDirectives.pdf'。这个错误让我很困惑，因为我认为该文件将直接从我的表单文件上传中获取。

我的假设错了吗？我应该保存然后以某种方式提供文件吗？

将文档上传到 Cloud Storage 的当前代码

    #Uploading Documents function
def upload_documents(bucket_name,source_file_name,destination_blob_name):
    storage_client = storage.Client()
    storage_bucket = storage_client.get_bucket(bucket_name)
    blob = storage_bucket.blob(destination_blob_name)
    blob.upload_from_filename(source_file_name)
    print("Document Uploaded")

from .forms import DocumentUpload
# Create your views here.
def get_upload(request):
    # If this is a POST request, we will process the data -- sending it to Google Cloud Storage

    if request.method == 'POST':
        #create a form instance populated with data -- (Bound to the data previously entered that might need correction)
        name = request.POST['name']
        titleofdocument = request.POST['titleofdocument']
        doc_file = request.POST['doc_file']
        fullUpload = name + "-" + titleofdocument + "-" + doc_file
        print(titleofdocument,name,doc_file)
        print(fullUpload)
        form = DocumentUpload(request.POST)
        upload_documents("upload_documents",fullUpload,"SampleBlob")

    else:
        form = DocumentUpload()

    return render(request, 'document-upload.html',{'form':form})

【问题讨论】：

你需要传递文件。 form = DocumentUpload(request.POST) 应该是 form = DocumentUpload(request.POST, request.FILES)。

标签： python django django-forms google-cloud-storage

【解决方案1】：

上传的文件在request.FILES。您没有将文件传递给表单。试试这个。

form = DocumentUpload(request.POST, request.FILES)

【讨论】：

感谢您，这可能使我走上了正确的道路。一个问题，因为我以前从未使用过request.FILES。有没有办法动态获取文件名？
