파일이 업로드되지 않고 데이터베이스에 저장되지 않습니다

Question

저는 장고에 파일을 저장하고 업로드하는 데 문제가있었습니다. 나는이 튜토리얼을 읽고 실행하고있다. 나는이 붙어 있었어요 :

'tuple' does not support the buffer interface 

문제는 views.py에서 오는 것으로 보인다, 그것은 절약 사이 어딘가에 중지합니다. 나는 ... 당신이 올바른 방향으로 날 지점 수있는 희망

• 업데이트 : 그것은 이제 데이터베이스에 저장 , 난 그냥 newdoc에서 모든 필드를 추가했습니다.

  file_path = request.FILES['file_path'] 
  

Answer 1

FileField는 업로드 된 파일 개체를 나타냅니다에서 내 테이블에 NULL 값을 허용하지 않는 문제가 있지만입니다. 따라서 파일이 아니라 경로이 아닌 파일을 전달해야합니다.

def index(request): 
    # Handle file upload 
    if request.method == 'POST': 
     form = DocumentForm(request.POST, request.FILES) 
     if form.is_valid(): 
      newdoc = Files(file_path = form.cleaned_data['file_path']) 
      newdoc.save() 
      # print(request) 

documentation on file uploads은 이것에 대해 자세히 설명합니다.

Answer 2

나는 이미 내 문제를 해결했다고 생각하며,이 솔루션을 게시 할 때이 작업을하려는 다른 초보자가있을 경우에 대비해 생각합니다. 참고 : 파일 필드의 이름을 'File_path'에서 내 DocumentForm에있는 'file'로 바꾸면 이름 혼란을 피할 수 있습니다.

def index(request): 
    # Handle file upload 
    if request.method == 'POST': 
     form = DocumentForm(request.POST, request.FILES) 

     if form.is_valid(): 
      # Upload the File 
      uploaded_file(request) 
      # Save in database 
      newdoc = Files(
       file_path = 'media/'+request.FILES['file_path'].name, 
       file_name = request.FILES['file_path'].name, 
       file_size = request.FILES['file_path'].size, 
       file_type = request.FILES['file_path'].content_type, 
       # Other data fields here.. 
      ) 
      newdoc.save() 

     # Redirect to the document list after POST 
     return HttpResponseRedirect(reverse('upload.views.index')) 
    else: 
     form = DocumentForm() # A empty, unbound form 

    # Load documents for the list page 
    documents = Files.objects.all() 

    # Render list page with the documents and the form 
    return render_to_response(
     'upload/index.html', {'documents': documents, 'form': form}, RequestContext(request) 
    ) 

def uploaded_file(request): 
    uploaded_filename = request.FILES['file_path'].name 

    # save the uploaded file inside that folder. 
    full_filename = 'media/'+uploaded_filename 
    fout = open(full_filename, 'wb+') 

    file_content = ContentFile(request.FILES['file_path'].read()) 

    # Iterate through the chunks. 
    for chunk in file_content.chunks(): 
     fout.write(chunk) 
    fout.close()
