The problem is that in your factory form, you named the field "image_1",
which then gets included in the filename, but in your actual db.imagebiens
table, the field name is "image". When the download function receives the
image name, it assumes the "imagebiens.image_1" prefix refers to table and
field name. It then checks that Field object in order to figure out its
associated uploadfolder. Of course, because there is no
db.imagebiens.image_1 field, this lookup fails.
