Question
In a Rails model how can I check if a URL on the same Rails server exists?
I'm using dragonfly and am trying to check the existence of an image from a path such as /media/BAhbBlsHOgZmIikyMDExLzExLzIxLzEwXzNxXzQyXzI5NF9Wb3NraG9kMi5qcGc
FileTest.exists? won't work because I don't have the file path and I can't open the URL because I don't have the server hostname.
Solution
You can get hostname from controller.
request.host
request.host_with_port
OTHER TIPS
Did you try using RAILS_ROOT
?
FileTest.exists?("#{RAILS_ROOT}/public/#{filename}")
