如何使用Django和Google App Engine Blobstore API上传文件 [英] How to upload a file using Django and Google App Engine Blobstore API

问题描述

我有一个我正在开发的应用程序：

• Django 1.5


• Google App Engine


• Google Cloud SQL


• Python 2.7.5

使用Cloud SQL我正在使用纯Django，而不是no-rel版本，充分利用了Django ORM。

在应用程式的管理员部分，我想使用表格上传使用GAE Blobstore API的csv档案。

我想要实现的是将文件上传到Blobstore和Blob Key，将引用此上传的文件保存在我的模型中。

去做这个吗

感谢您的帮助。

解决方案

将文件作为Django表单的一部分上传，您可以按照BlobStore指令手动处理uplaod，然后获取BlobKey，并将其保存为Django模型中的字符串。这可能是最直接的方式。

另一种选择是将存储组件djangoappengine（专为Django-nonrel设计），并适应它与普通的Django一起使用。我不认为这有什么理由不适用（在你做了一些努力去适应之后）

I have an app I am developing using:

• Django 1.5
• Google App Engine
• Google Cloud SQL
• Python 2.7.5

As using Cloud SQL I am using the pure Django not the no-rel version making full use of the Django ORM.

In the admin part of the app I want to have a form to upload a csv file using GAE Blobstore API.

What I want to achieve is the uploading of the file to the Blobstore and the Blob Key referencing this uploaded file to be saved in my model.

How would I go about doing this?

Thanks for your help.

解决方案

If you're not uploading the file as part of a Django form, you can manually handle the uplaod as per BlobStore instructions, then fetch the BlobKey, and save it as a string in your Django model. That's probably the most straighforward way to go.

https://developers.google.com/appengine/docs/python/blobstore/

Another option is to take the storage component in djangoappengine (designed for Django-nonrel), and adapt it for use with normal Django. I don't think there's any reason why this shouldn't work (after you put some effort into adapting it)
