Avatar image upload upon replacement.

[lehins]

Avatar image uploading works fine, same with replacement of the image if the file was selected.
There is an exception:

'ImageFieldFile' object has no attribute 'content_type'

when clicked on upload button without selecting a new file, but only after initial upload.
The reason is that when no file selected

djangobb_forum.fields.ExtendedImageField.save_form_data()

gets an argument 'data' of type ImageFieldFile? instead of InMemoryUploadedFile?.
The way I fixed it was just to check for the instance type:

    def save_form_data(self, instance, data):
        if data and self.width and self.height and isinstance(data, InMemoryUploadedFile):
            content = self.resize_image(data.read(), width=self.width, height=self.height)
            salt = sha1(str(random.random())).hexdigest()[:5]
            fname =  sha1(salt + crowdsite.settings.SECRET_KEY).hexdigest() + '.png'
            data = SimpleUploadedFile(fname, content, data.content_type)
        super(ExtendedImageField, self).save_form_data(instance, data)

I hope the fix will be applied in future, or other solution to the bug implemented. Thanks, and thank you for the fine forum.

same bug was fixed 1 month ago

i set content_type='image/png' becouse we always converted images to png, maybe this field will be replaced to sorl later, but i don't like 100500 dependence :)
