Rendering array of file names

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?

in helper

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

end

In view

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

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.
