ruby on rails - error accessing to public directory

Question

I would like to ask you if is possible to show data, which I've to saved in /public/my_dir_for_data.

If I try to display an image from this directory, I get "Routing error". Probably when I would to saved the data to root of my application, e.g. /my_data, everything will be ok... but I like this structure of RoR application and I will be glad, if I could to use the directory in in /public...

Exist any way, how to do? (and simultaneously security?)

Answer 1

If a file exists, rails won't go into the controller stack, if it can't find the file, it will assume that it's a dynamic action and go into the controller stack.

So, if a file exists at #{Rails.root}/public/directory/file.png and you navigate to domain.com/directory/file.png it should work render the file.

Are you sure all the directory and file names are the same on both sides?
