Simply save file to folder in Django
提问by Jon
I have a piece of code which gets a file from a form via POST.
我有一段代码，它通过 POST 从表单中获取文件。
file = request.FILES['f']
What would be the simplest way of saving this file to my media folder in
将此文件保存到我的媒体文件夹的最简单方法是什么
settings.MEDIA_ROOT
I was looking at this answer, among others, but I had errors refering to undefined names and invalid "chunks" method.
我正在查看这个答案等，但我在引用未定义的名称和无效的“块”方法时出错。
There must be a simple way to do this?
必须有一个简单的方法来做到这一点？
EDITUpload method in my views.py:
在我的 views.py 中编辑上传方法：
def upload(request):
folder = request.path.replace("/", "_")
uploaded_filename = request.FILES['f'].name
# create the folder if it doesn't exist.
try:
os.mkdir(os.path.join(settings.MEDIA_ROOT, folder))
except:
pass
# save the uploaded file inside that folder.
full_filename = os.path.join(settings.MEDIA_ROOT, folder, uploaded_filename)
fout = open(full_filename, 'wb+')
file_content = ContentFile( request.FILES['f'].read() )
# Iterate through the chunks.
for chunk in file_content.chunks():
fout.write(chunk)
fout.close()

You can use django FileField, it support specify a upload_toparameter, like this:
您可以使用 django FileField，它支持指定upload_to参数，如下所示：

you can upload files to django server : :
您可以将文件上传到 django 服务器 ::
from django.shortcuts import render
from django.conf import settings
from django.core.files.storage import FileSystemStorage
def upload(request):
folder='my_folder/'
if request.method == 'POST' and request.FILES['myfile']:
myfile = request.FILES['myfile']
fs = FileSystemStorage(location=folder) #defaults to MEDIA_ROOT
filename = fs.save(myfile.name, myfile)
file_url = fs.url(filename)
return render(request, 'upload.html', {
'file_url': file_url
})
else:
return render(request, 'upload.html')

Using default_storageis better than FileSystemStorage.
使用default_storage比FileSystemStorage.
You can save file to MEDIA_ROOTwith FileSystemStoragebut when you change DEFAULT_FILE_STORAGEbackend in the future this may not work anymore.
您可以将文件保存到MEDIA_ROOTwithFileSystemStorage但是当您DEFAULT_FILE_STORAGE将来更改后端时，这可能不再起作用。
If you use default_storage, in the future if you want to use aws, azure etc as file store with multiple Django worker your code will work without any change.
如果您使用default_storage，将来如果您想使用 aws、azure 等作为具有多个 Django 工作器的文件存储，您的代码将无需任何更改即可运行。
default_storage usage example:
default_storage 用法示例：
from django.core.files.storage import default_storage
# Saving POST'ed file to storage
file = request.FILES['myfile']
file_name = default_storage.save(file.name, file)
# Reading file from storage
file = default_storage.open(file_name)
file_url = default_storage.url(file_name)

Use the following code to update a FileFieldor ImageField. Django will upload the file to settings.MEDIA_ROOTper default.
使用以下代码更新 aFileField或ImageField. Django 将settings.MEDIA_ROOT默认上传文件。
from os.path import basename
from django.core.files import File
self.model.file_field.save(basename(path), content=File(open(path, 'rb')))
Afterwords you can access:
后记您可以访问：
The path like this:
路径是这样的：
self.model.file_field.path
The url like this:
网址是这样的：
self.model.file_field.url
