Question

我有以下情况：

models.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)

views.py

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

这样，文件是否自动上传？如果不是，我想按照文档中的建议将其分块，我尝试了以下

models.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)

views.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)

它可以正常工作，但文件存储两次，名称符合Django文档，例如 myFile.zip 和* myFile_1.zip *。与save()一起存储的那个我不确定它是否被分块。你能否向我解释一下，如果在模型框架中自动分块，可能会给我一个有效的例子吗？我是否要重新定义save()方法以便正常存储“名称”字段并将“文件”字段分块？感谢。
