Problem viewing photos in Paperclip - routes error

Question

I have set up Paperclip and ImageMagick successfully on my system, and files are uploading correctly, being resized, and and being saved into the right folders.

I try to display those images in my view:

<%= image_tag @customer.logo.url(:medium) %>

No image is displayed. When I go to the image's direct url I get:

Routing Error
No route matches "/images/assets/logos/1/medium/corplogo.jpg" with {:method=>:get}

This is a local server still in development and running on Windows. My forms are multipart:

<% form_for @customer, :url => {:action => "update", :id => @customer}, :html => {:multipart => true, :id => "myform"} do |f| %>

    :path => ":rails_root/public/assets/logos/:id/:style/:basename.:extension",
    :styles => {:medium => "300x300>", :thumb => "100x100>" }

Answer 1

I found the answer to the problem, and it lies with the url declaration in the model.

Instead of:

:url => "assets/logos/:id/:style/:basename.:extension"

it should be:

:url => "/assets/logos/:id/:style/:basename.:extension"
