10121	ImageField (and FileField) loses data when re-saving from admin	Ville Säävuori	Karen Tracey	"I have a following model with an `ImageField`:

{{{
class PublicCategoryManager(models.Manager):
    """"""
    Custom manager for displaying only public categories.
    """"""
    def get_query_set(self):
        return super(PublicCategoryManager, self).get_query_set().filter(is_public=True)
    
class Category(models.Model):
    """"""
    Category for products. Can relate to itself.
    """"""
    name = models.CharField(max_length=200)
    parent = models.ForeignKey('self', blank=True, null=True, related_name='child', verbose_name='parent')
    image = models.ImageField(blank=True, null=True, upload_to='categories/')
    is_public = models.BooleanField(default=True)

	 ...

    objects = models.Manager()
    public_objects = PublicCategoryManager()

    def save(self, force_insert=False, force_update=False):
        if not self.date_added:
            self.date_added = datetime.now()
        ...
        super(Category, self).save(force_insert, force_update)

}}}

it has a following Admin class 

{{{
class CategoryAdmin(admin.ModelAdmin):
    ...
    save_as = True
    save_on_top = True
    prepopulated_fields = {""slug"": (""name"",)}
    raw_id_fields = ('parent',)
}}}

Image works OK when first saving it. But when re-saving the object (with of without editind any data) from the admin, the data on the imagefield (in db) is erased. When saving the data from python shell everything works OK.

We're using Python 2.5 and the latest SVN version (r9791) of Django."		closed	contrib.admin	dev		fixed	admin, ImageField, save		Accepted	0	0	0	0	0	0
