Django Azure загрузить файл в хранилище BLOB-объектов

0 голосов
/ 17 февраля 2019

У меня есть приложение, которое должно загрузить файл в контейнер хранилища BLOB-объектов Azure.Я очень долго пытался и следовал каждому учебнику безрезультатно.

Я установил следующее: 

pip3 install django-storages[azure]

Вот мой файл settings.py: 

DEFAULT_FILE_STORAGE = 'backend.custom_azure.AzureMediaStorage'
STATICFILES_STORAGE = 'backend.custom_azure.AzureStaticStorage'

STATIC_LOCATION = "static"
MEDIA_LOCATION = "http://{AZURE_ACCOUNT_NAME}.blob.core.windows.net/media"
MEDIA_ROOT='http://{AZURE_ACCOUNT_NAME}.blob.core.windows.net'

AZURE_ACCOUNT_NAME = '<mystorageaccount>'
AZURE_ACCOUNT_KEY = '<my key here>'
AZURE_CUSTOM_DOMAIN = f'{AZURE_ACCOUNT_NAME}.blob.core.windows.net'
AZURE_LOCATION=f'{AZURE_ACCOUNT_NAME}.blob.core.windows.net'

STATIC_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{STATIC_LOCATION}/'
MEDIA_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{MEDIA_LOCATION}/'

Вот .backend / custom_azure.py <- мой класс хранения для клиентов </p> 

from storages.backends.azure_storage import AzureStorage

class AzureMediaStorage(AzureStorage):
    account_name = '<mystorageaccount>' 
    account_key = '<mykey>'
    azure_container = 'media'
    expiration_secs = None

class AzureStaticStorage(AzureStorage):
    account_name = 'mystorageaccount'
    account_key = '<my key>'
    azure_container = 'static'
    expiration_secs = None

Вот мой .account / models.py: 

from django.db import models
from django.urls import reverse
from django.contrib.auth.models import User
from billing.models import Subs
from PIL import Image
import phonenumbers
from backend.custom_azure import AzureMediaStorage as AMS

class MasterAccount(models.Model):
    image = models.ImageField(default='default.jpg', storage=AMS, upload_to='profile_pics')
    profile_pic = models.FileField(default='default.jpg', storage=AMS, upload_to='profile_pics')

    def __str__(self):
        return "MasterAccount Number: " + str(self.number)

    def save(self, *args ,**kwargs):
        super().save(*args ,**kwargs)
        img =  Image.open(self.image.path)

        if img.height > 300 or img.width > 300:
            output_size = (300, 300)
            img.thumbnail(output_size)
            img.save(self.image.path)

IЯ запускаю это в Apache. (не runserver)

ПРОБЛЕМА: я выяснил, что с этой конфигурацией я могу получить все файлы из хранилища BLOB-объектов, включая медиа-файлы и статические файлы.Все они появляются идеально.Однако, когда я пытаюсь добавить и сохранить экземпляр MasterAccount, он barfs с ошибкой абсолютного пути:

Так что, похоже, несмотря ни на что, он просто передает имя файла «default.jpg», но не делает »не знаете куда его отправить?

Нужно ли менять настройки в лазури?Мой конфиг все не так?Пожалуйста помогите, я ломал голову над этим и утомлял Google в течение приблизительно 3 недель!Спасибо !!!

ОБНОВЛЕНИЕ

После полезного предложения, приведенного ниже, я могу, по крайней мере, теперь войти в панель администратора.но всякий раз, когда я пытаюсь отредактировать модель MasterAccount, нажимая на нее, я получаю ошибку typeError:

Разобрался с проблемой.Я следовал руководству по Amazon S3, а затем применил те же принципы к сценарию Azure.В конце концов, я уверен, что разработчик этого класса хотел, чтобы все было одинаково.

mysite / custom_azure.py <- просто поместите его в ту же папку, что и ваш файл settings.py </p> 

from storages.backends.azure_storage import AzureStorage

class AzureMediaStorage(AzureStorage):
    location = 'media'
    file_overwrite = False

mysite / settings.py 

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, '<directory that houses the static files>/static'),
]

AZURE_ACCOUNT_NAME = '<azure container name>'
AZURE_ACCOUNT_KEY = '<azure account key for this container>'
AZURE_CUSTOM_DOMAIN = f'{AZURE_ACCOUNT_NAME}.blob.core.windows.net'
AZURE_LOCATION = '<blob container name>'
AZURE_CONTAINER = '<blob container name>'

STATIC_LOCATION = 'static'
STATIC_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{STATIC_LOCATION}/'

STATICFILES_STORAGE = 'storages.backends.azure_storage.AzureStorage'
DEFAULT_FILE_STORAGE = 'mysite.custom_azure.AzureMediaStorage'

Также обратите внимание, что если у вас есть следующее в вашем mysite / urls.py из какого-то другого учебника или чего-то еще: 

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

вам нужно удалить строку MEDIA: 

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

из модели, удалить любую ссылку на «хранилище» и просто оставить опцию «upload_to» следующим образом: 

thumbnail = models.ImageField(default='default.jpg', upload_to='video_thumbs')

все этопросто работал.

не заставляйте себя делать следующее, чтобы проверить себя: 

python3 manage.py collectstatic

надеюсь, это поможет другим людям !!!

Я просмотрел исходный код azure_storage.py из jschneier/django-storages для хранилища Azure и документ для Хранение Azure , ваша проблема вызвана невернойзначение AZURE_LOCATION в settings.py, которое должно быть "" или префиксная строка большого двоичного объекта в качестве имени подпапки в контейнере, например <container name>/<prefix string as AZURE_LOCATION, such as A/B/..../ ><filename>.

Вывод основан на анализе кода ниже.

Функция _get_file при LINE 34 ниже использовала self._storage.service.get_blob_to_stream метод Storage SDK, а значение параметра blob_name равно self._path, которое появилось self._path = storage._get_valid_path(name) при LINE 32 внутри __init__ функции дляAzureStorageFile: 

#LINE 32 inside def __init__(self, name, mode, storage):
    self._path = storage._get_valid_path(name)

# LINE 34
def _get_file(self):
    if self._file is not None:
        return self._file

    file = SpooledTemporaryFile(
        max_size=self._storage.max_memory_size,
        suffix=".AzureStorageFile",
        dir=setting("FILE_UPLOAD_TEMP_DIR", None))

    if 'r' in self._mode or 'a' in self._mode:
        # I set max connection to 1 since spooledtempfile is
        # not seekable which is required if we use max_connections > 1
        self._storage.service.get_blob_to_stream(
            container_name=self._storage.azure_container,
            blob_name=self._path,
            stream=file,
            max_connections=1,
            timeout=10)
    if 'r' in self._mode:
        file.seek(0)

    self._file = file
    return self._file

Затем функция storage.__get_valid_path с зависимой функцией _path в LINE 173: 

#LINE 147
location = setting('AZURE_LOCATION', '')

#LINE 173
def _path(self, name):
    name = _clean_name_dance(name)
    try:
        return safe_join(self.location, name)
    except ValueError:
        raise SuspiciousOperation("Attempted access to '%s' denied." % name)

def _get_valid_path(self, name):
    # Must be idempotent
    return _get_valid_path(self._path(name))

def _open(self, name, mode="rb"):
    return AzureStorageFile(name, mode, self)

def get_valid_name(self, name):
    return _clean_name_dance(name)

def get_available_name(self, name, max_length=_AZURE_NAME_MAX_LEN):
    """
    Returns a filename that's free on the target storage system, and
    available for new content to be written to.
    """
    name = self.get_valid_name(name)
    if self.overwrite_files:
        return get_available_overwrite_name(name, max_length)
    return super(AzureStorage, self).get_available_name(name, max_length)

Таким образом, вы можете увидеть код возврата blob_name от _path до _get_valid_path, который присоединился к AZURE_LOCATION с name.Если использовать {AZURE_ACCOUNT_NAME}.blob.core.windows.net в качестве location, имя загружаемого большого двоичного объекта будет отличаться от загруженного имени большого двоичного объекта, а не однозначного соответствия.
