How To Get A List Of All Currently Registered MIME Types With Rails

Posted by Weston Ganger

Rails was complaining about mime types already registered, so I wanted to check what MIME types were already registered in my app.

We can do this easily through Rails console.


# List all registered
Mime::EXTENSION_LOOKUP.map{|x| x}

# Or Check for a specific type
Mime::Type.lookup_by_extension(:pdf)
