Django-tastypie: Any example on file upload in POST?

Could anyone give a complete example on using the tastypie FileField, both server-side and client-side please?

Here's what I have tried:

#models.py
class Foo(models.Model):
    img = models.ImageField(upload_to="images", null=True, blank=True)
    body = models.CharField()

#api.py
class FooResource(ModelResource):
    img = fields.FileField(attribute="image", null=True, blank=True)
    class Meta:
        queryset = Foo.objects.all()

If I try to create a foo object using curl, e.g.,

>>> curl -F "body=test" -F "img=@local_img.png" http://localhost:8000/api/0.1/foo/

A foo object is successfully created, but the img field is null. I can see in debugger that when saving the bundle object indeed has a img field which contains a InMemoryUploadedFile object, so the request is probably ok. Where am I doing wrong? Code snippets are most welcome, thanks!

Your Resources should look like this:

class FooResource(ModelResource):
    img = fields.FileField(attribute="img", null=True, blank=True)
    class Meta:
        queryset = Foo.objects.all()

The attribute should correspond to the field in the model. As stated in the documentation:

ApiField.attribute

A string naming an instance attribute of the object wrapped by the Resource.
