File Type Extensions Missing in Uploaded Files

I'm using paperclip version 2.5.0 to upload text-like documents (word,
text, pdf). While uploads do take place there are two show-stopping
issues:

1. Regardless of which file type is used (doc, txt, pdf) the resultant
uploaded file ALWAYS ends with a "." (dot).

2. The "path" property returns the path and filename WITHOUT the dot, so
the file can not be accessed.

I've pasted the model that contains the attachment code at:

Does anyone know what could be wrong? Thanks.

I was checking the project page https://github.com/thoughtbot/paperclip
and it says paperclip is failing... maybe that's the reason

I think you should debug the normalize_file_name method and check the extension variable
