我有以下情况：

  • 模型.py

    class ShapeFile(models.Model):
    name = models.SlugField()
    file = models.FileField(upload_to=get_upload_path)

def get_upload_path(instance, filename):
    return os.path.join("my","custom","path",filename)

  • 视图.py

    def shapeIng(request):
    if request.method == 'POST':
        form = UploadForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()

这样上传的文件是不是自动分块了？如果不是，我想按照文档中的建议将其分块，我尝试了以下方法

  • 模型.py

    from django.core.files.storage import default_storage

class ShapeFile(models.Model):
    name = models.SlugField()
    file = models.FileField(upload_to=get_upload_path)

def get_upload_path_2(filename):
   return os.path.join(default_storage.path(''),"my","custom",
       "path","%s" % filename)

  • 视图.py

    from os import makedirs
form os.path import dirname
from django.core.files.storage import default_storage

def shapeIng(request):
    if request.method == 'POST':
        form = UploadForm(request.POST, request.FILES)
        if form.is_valid():

            # Split uploaded file into chunks
            fileName = request.FILES['file']
            filePath = get_upload_path_2(fileName)
            handle_uploaded_file(fileName, filePath) # Uploads the file

            form.save() # Uploads the file again!!!

def handle_uploaded_file(fileName, filePath):
    makedirs(dirname(filePath))
    with open(filePath, 'wb+') as destination:
        for chunk in fileName.chunks():
            destination.write(chunk)

它可以工作，但文件会以符合 Django 文档的名称存储两次，例如myFile.zip和 *myFile_1.zip*。与我一起存储的那个save()我不确定它是否被分块。您能否向我解释一下分块是否在 ModelForm 中是自动的，并可能给我一个工作示例？我是否需要重新定义save()方法以正常存储“名称”字段并分块“文件”字段？谢谢。
