You can place this snippet in management/commands/ and have it upload files from disk into objects in your database. Usage: ``` python manage.py upload_file_to_model myapp mymodel myfield 1 field_name /some/file/path ```
This snippit is meant to be used with the pre_delete signal to delete any files associated with a model instance before the instance is deleted. It will search the model instance for fields that are subclasses of FieldFile, and then delete the corresponding files. As such, it will work with any model field that is a subclass of FileField.
This code runs well on Django 1.4 also with the Admin panel. It's important to get the storage and the path before delete the model or the latter will persist void also if deleted.

This snippet in the one to improve the method described in [http://djangosnippets.org/snippets/679/](http://djangosnippets.org/snippets/679/). It uses some jquery extensions to make the task more easier: **jquery.timers.js**, **jquery.progressbar.js**, **jquery.form.js**.
Usage described in this blog post: [Django: FileField with ContentType and File Size Validation](http://nemesisdesign.net/blog/coding/django-filefield-content-type-size-validation/) Snippet inspired by: [Validate by file content type and size](http://djangosnippets.org/snippets/1303/)
The title says it all — a subclass of FileSystemStorage which will overwrite files. Note that saves which fail part way though will leave the original file intact (see `test_upload_fails`). Based roughly on http://djangosnippets.org/snippets/2044/ .
There's no direct way to save the contents of a URL to a Django File field: you're required to use a File instance but those can only safely wrap normal files, not the file-like object returned by urllib2.urlopen. Several examples online use urllib.urlretrieve() which creates a temporary file but performs no error handling without writing a ton of hackish code. This demonstrates how to create a NamedTemporaryFile, fill it with the URL contents and save it, all using APIs which raise exceptions on errors.
`GzipFileSystemStorage` is a `FileSystemStorage` subclass that transparently compresses files. [More Info](http://theidioteque.net/blog/2009/9/29/gzipfilesystemstorage/)
A simple way to handle file validation by checking for a proper content_type and by making sure that the file does not go over its limit upload size limit. In the example I am checking to make sure the file is an image or a video file then I check to make sure that the file is below the max upload limit. if conditions are not met, then a validation error is raised
In-browser testing frameworks (I'm using [Windmill](http://www.getwindmill.com/)) have trouble testing file uploads because javascript's security policy prevents them from setting the value of file input fields. Instead the tests must issue some sort of "fake" file upload request, but implementing this on an ad-hoc basis quickly gets ugly. This middleware is designed to support fake file uploads as transparently and as thoroughly as possible. For example, it is careful to properly trigger any file upload handlers so that things like upload progress reporting will work correctly. It can also simulate a slow file upload by sleeping between reads from the file. From the client-side point of view, each input field of type "file" has a similarly-named hidden field automatically prepended. Test scripts can simply set the value of this hidden field to trigger a fake upload, rather than having to set the value of the file input field itself.
This function emulates the file upload behaviour of django's admin, but can be used in any view. It takes a list of POST keys that represent uploaded files, and saves the files into a date-formatted directory in the same manner as a `FileField`'s `upload_to` argument.
A FileField Widget that displays an image instead of a file path if the current file is an image. Could also be used with sorl.thumbnail to generate thumbnail images. **Example** class FileUploadForm(forms.ModelForm): upload = forms.FileField(widget=AdminThumbnailWidget) class Meta: model = FileUpload class FileUploadAdmin(admin.ModelAdmin): form = FileUploadForm admin.site.register(FileUpload, FileUploadAdmin)
This adds a checkbox in the admin site that removes the reference to a file uploaded via a FileField (or ImageField). It does not delete the actual file.
