Attachment_fu_fixtures problem

Hey guys,

I’m using attachment_fu plugin to upload images. It’s working fine and I
wanted to add some fixtures for testing and all that. The readme says
you online need to install the plugin and put "attachment_file: " into
the yml files.

The problem is that I get following error:
Mysql::Error: Unknown column ‘attachment_file’ in ‘field list’: INSERT
INTO photos (attachment_file, description) VALUES
(‘public/images/victoria.jpg’, ‘default’)

Since there’s nothing to do but extract the plugin into the
vendor/plugins folder I have no idea what to do. Anyone had the same
problem and can help me with that?
