Update : Implementation for Django 1.5 at GitHub. Even though there is few changes the following tutorial is also useful for 1.4. Update : The source at GitHub has also implementation for Django 1.4 in addition to 1.3. To download source for the project, visit or clone it: > git clone With that knowledge I implemented a project that makes possible to upload files and show them as list. I spent over 2 hours to dig up all the pieces to understand how this works. The same function is available as a template filter.Phew, Django documentation really does not have good example about this. Returns None if no URL could be generated. Tries to generate a publicly accessible URL for the given file.

By default the content type will be detected via mimetypes.guess_type() using file.name.

content_type: Overrides the file's content type in the response.

The default is to let the browser decide how to handle the download. Alternatively, you can pass a string to override the file name. If this is True the file object's name attribute will be used as the file name in the download dialog.

save_as: Forces the browser to save the file instead of displaying it (useful for PDF documents, for example).

So, you always have to provide a view that uses this function. This is used either for checking permissions before approving a downoad or as a fallback if the backend doesn't support publicly accessible URLs. Serve_file(request, file, backend=None, save_as=False, content_type=None)

backend: If defined, you can override the backend specified in settings.py.

If True the backend will try to make the upload non-accessible to the public, so it can only be served via serve_file().

private: If False the backend will try to make the upload publicly accessible, so it can be served via the public_download_url template filter.

url: The target URL where the files should be sent to.

Returns a tuple with a target URL for the upload form and a dict with additional POST data for the upload request. Prepare_upload(request, url, private=False, backend=None) Please take a look at the backends which are shipped with django-filetransfers to see if something fits your solution better. This default configuration should work with practically all servers, but it's not the most efficient solution. The default public downloads backend simply returns None. The default download backend transfers the file in chunks via Django, so it's definitely not the most efficient mechanism, but it uses only a small amount of memory (important for large files) and requires less resources than passing a file object directly to the response. The default upload backend simply returns the URL unmodified. PUBLIC_DOWNLOAD_URL_BACKEND = '_download_url' You can specify the backends in your settings.py: PREPARE_UPLOAD_BACKEND = '_upload' There are three backend types which are supported by django-filetransfers: one for uploads, one for downloads via serve_file(), and one for public downloads.

Otherwise the public download URL is used. template tag returns the second argument which is our fallback URL. Return direct_to_template(request, 'upload/upload.html', Upload_url, upload_data = prepare_upload(request, view_url) View_url = reverse('_handler')įorm = UploadForm(request.POST, request.FILES) This is an example upload view: from filetransfers.api import prepare_upload

The extra POST data is just a dict, so you can pass it to your JavaScript code if needed. Handling uploadsįile uploads are handled with the prepare_upload() function which takes the request and the URL of the upload view and returns a tuple with a generated upload URL and extra POST data for the upload. convert uploaded images via the Image API. Note for App Engine users: When accessing a file object from UploadedModel you can get the file's BlobInfo object via _info. The upload_to parameter for FileField defines the target folder for file uploads (here, we add the date). In the following we'll use this model and form: class UploadModel(models.Model):įile = models.FileField(upload_to='uploads/%Y/%m/%d/%H/%M/%S/')

Otherwise, the Blobstore API is disabled. In order to use the Blobstore on the App Engine production server you have to enable billing. You don't need any special configuration. Note for App Engine users: All nrequired backends are already enabled in the default settings. Then, add "filetransfers" to your INSTALLED_APPS.

You can install the package via setup.py install or by copying or linking the "filetransfers" folder to your project (App Engine developers have to use the copy/link method).
