This won't work as you expect. The first file named 'foo' will be saved
as 'foo'. The second as 'foo_2', but the third will still only return a
count of 1 (since you are doing an exact match of the name) and you'll
attempt to save it as 'foo_2' also.
You could try changing the query line to something like:
c = Photo.objects.filter(name__startswith=self.name).count()
but that's not really right either since you'd find matches if
self.name was a prefix of another photo.
You might just want to do an os.listdir() to be certain. Something
like:
i, name = 1, self.name
files = [f for f in os.listdir(SAVE_DIR) if
f.startswith(self.name)]
while name in files:
name = self.name + '_' + str(i)
i = i + 1
self.name = name
