New Rails Plugin Mimetype_fu

mimetype_fu/ is a new plugin I just wrote. It’s simple and it can be really useful if you need to get the mime type of a file already on your server.

During one of my project, I add to migrate old assets from a legacy system to a new Rails app. The new app uses attachment fu and even though techno weenie did an amazing job, attachment_fu validation is based on the content type. A_fu gets the content type coming from the CGI query.

Unit test has a helper faking this process but in real life, if you use a Flash uploader (Flash doesn’t give you the proper mime type/content type) or if you want to migrate files, the attachment_fu validation won’t work for you.

The solution is simple: mimetype_fu/

mimetype_fu/ extends the File class and is really easy to use:

Expect a post showing how a ninja would use the mimetype_fu / attachment_fu combo :)
