Displaying images from directory in ruby on rails3

Question

I am developing simple web application in ruby on rails 3, where users can upload images and uploaded all images has to be displayed. Successfully i uploaded images into folder(photos) which is located in public and stored their url path in database.I am getting problem in displaying images.

image.html.erb

<% @photo.each do |photo| %>
  <table>
    <tr> 
      <td><img src = "#{photo.url}" /></td>
    </tr>
  </table>
<%end%>

in photos controller

def image
  @photo = Photo.all
end

when iam giving path(photos/pic1.jpg) the loop has been working but it displaying only one image, if iam using photo.url it has been not displaying any image.

To render some variable value into erb template you should use <%= ... %> instead of regular string interpolation #{...}. In your case you can do:

<img src = "<%= photo.url %>" />

Or, better, you can use image_tag helper:

<%= image_tag photo.url %>
