关于python：Flask-Uploads：如何与Application Factory一起使用

Flask-Uploads : how to use with application factory

我正在尝试在我的项目中实现Flask-Upload。但是，我遇到了麻烦，因为我正在使用应用程序工厂功能，并且无法从应用程序中的其他文件访问UploadSet！

文件：app / __ init __。py

from flask_uploads import UploadSet, configure_uploads, IMAGES

def create_app(object_name):
...
images = UploadSet('images', IMAGES)
configure_uploads(app, images)

文件：app / controllers / editions.py

from flask_uploads import UploadNotAllowed

# this is one of my route files, registered in a blueprint
editions = Blueprint('editions', __name__)

...
# inside one of the routes
poster = request.files.get('poster')
try:
filename = images.save(poster)
except UploadNotAllowed:
flash('The upload was not allowed.', category='warning')
else:
# add to db...

这当然是行不通的，因为未定义images。但是如何从应用程序导入它？

我尝试过：

import app
app.images.save(...)

from flask import current_app
current_app.images.save(...)

from app import images

均无效。
有什么想法吗？

PS：除此以外，我的应用程序中的所有其他东西都工作正常。

我在这里发布后马上就知道了。它很简单，但是找不到它的解释：

在控制器/视图文件上，路径为：

from flask_upload import UploadSet, IMAGES

my_upload_set = UploadSet('my_upload_set', IMAGES)

# (...) routes where you can use:
image = request.files.get('image') # or whatever your form field name is
try:
filename = my_upload_set.save(image)
except UploadNotAllowed:
flash('The upload was not allowed.', category='warning')
else:
# add to db

在app/__init__.py文件上：

from app.controllers.my_view import my_upload_set
from flask_uploads import configure_uploads

def create_app(object):
(...)
configure_uploads(app, my_upload_set)

这应该像一种魅力！
任何问题都让我知道...
