If you try to access to .read() in an InMemoryUploadedFile object, you'll
get an empty string unless you don't call .seek(0) so it gets to the
beginning of the file.
To test, just write a model like this:
{{{
#!python
class TestModel(models.Model):
photo = models.ImageField(upload_to='test/',
validator_list=[validators.CustomValidator()])
class Admin:
pass
}}}
And this validator:
{{{
#!python
class CustomValidator(object):
def __call__(self, field_data, all_data):
print "Size: " + str(field_data.size)
print "Len: " + str(len(field_data.read()))
}}}
We get:
{{{
Size: 378054
Len: 0
}}}
Attached patch solves this issue.
