Rendering array of file names

Question

I'm trying to print list of files from current directory. I used

@files = Dir.glob('*')

and in views i'm trying to print using

<%= @files.each {|file| puts "<li>" + file + "</li>"}%>

But instead it prints me just array of filenames, without <li> tag. WHat am i doing wrong?

Have you ensured you're viewing the raw output, not rendered in the browser's viewport? — alex

As alex said, puts will probably push it to server logs, here's what you can do:

<% @files.each do |file| %>
  <li><%= file %></li>
<% end %>

Since you have the = before the @files, you're seeing the string output of an array.

use

<% @files.each do |file| %>
<li> <%= file %></li>
<% end %>

You seem to not get the syntax of erb syntax right.

puts will print the values in logfile not on webpage

in helper

def display_files(dir='*')
 list = ""
 files = Dir.glob(dir)
 @files.each do |file|
  list << "<li>#{file}</li>"
 end
list

end

In view
