How to render a text file without changing its formatting?
Currently I am using
<%= File.read(''/path/to/file.txt'') %>
to render my file on the screen, but this puts the whole file in one
line. How would I output the file on the screen the way it is saved in
the .txt document? (I can''t use render_file)

But browsers don''t have any particular rules for plain text, and will run them out in a single line if that''s all that is there. You might try running it through the simple_format view helper to see if that fixes things for you. That will at lease put a br at the end of each single line break and a p at every double-line-break. It''s not going to render other tags, like lists or similar.

For instance if you''re getting that file from an end user through some sort of file upload you better make sure you sanitize it before sending it back to the browser to be rendered. That''s what we would call "user provided data" and you should never trust user provided data. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If not on 3 then certainly it must be sanitised. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
