Comment:
Sorry to re-open, but the notion that an error is raised when attempting
to access attributes on a missing file is a wildly impractical default.
It assumes that "everyone at all times will have a full, up-to-date copy
of the media folder, that is exactly in sync with the database they're
running against".
If you're coding in a little bubble, eg pre-launch, against some bollocks
test data-- sure, lets raise errors and annoy ourselves. But in the "real
world" this is often/usually not the case and means you have to move
around massive media libraries and databases just to work on the site at
all, without resorting to temporarily commenting stuff out or hacking up a
custom field.
The default should be to return None, overridable through the field/model
definition (eg silent=False). And there should be an exists() method too,
why not? @aaugustin your presumption above "that you have bigger problems"
is totally irrelevant in many production scenarios.
