Rails - Jun 2009 - How to persist file upload fields after a validation error.

Hi all,

Is there an easy way to not lose the file field input from the user
after a validation error?  It pisses people off to have to choose
their files again just because some other field didn''t pass a
validation.  I''ve googled this and just haven''t come up with
much of
anything.

Thanks.

I''m pretty sure you can''t do that for security reasons. 
Nothing to do
with rails of course it''s just a browser thing.

Just imagine if you could pre-fill file upload fields!

Good luck!

I save the file and store it''s location in a session variable, then
you can get to the file again on resubmission.
You will need a strategy to clean up orphaned files where the user has
not re-submitted the form
