Filename

Rails
1

Hi,

I am using attachment_fu plugin for uploading files. Can anybody tell me
how to access the filename in the Model before the file gets uploaded ?
Actually I want to a system where the users will be able to upload files
if the filenames matches with the existing filenames already stored in a
different table. Can anybody advice me on how to solve this problem ?

Thanks
Saurav

as far as i understand, using attachment_fu, you cannot get the
filename in the Model BEFORE the file gets uploaded.

One solution to you problem could be :

i. Make the use enter the filename (or path) in a textfield.
ii. Make an ajax call to the server with the filename, to verify
whether it exists in the database.
iii. Enable the upload button / display error message depending on the
result of the ajax call.
