Post-processing for Django FileFields.

Project description

django-processedfilefield: Post-processing for Django FileFields. Takes a dict of field names on the model, mapped to post-processing functions. These functions could convert a PDF to text, thumbnail an image, etc.

Example:
>>> class TestModel(models.Model):
...     content = ProcessedFileField(upload_to='content', variations=dict(
...         content_first_10_bytes=lambda file: file.read()[:10]
...     ))
...     content_first_10_bytes = models.FileField(upload_to='content_first_10_bytes')
...
>>> obj = TestModel.objects.create()
>>> obj.content = ContentFile('abcdefghijklmnopqrstuvwxyz')
>>> obj.content.name = 'alphabet'
>>> obj.save()
>>>
>>> assert obj.content_first_10_bytes.read() == 'abcdefghij'
