How to specify :path and :url to save img in Paperclip, Rails 3.0.12

Question

I'm using Paperclip with my Rails 3.0 app in order to add an avatar to a user, and it won't save the image because the paths are off. Heres what I get:

Started GET "/profilepics/small/missing.png" for 127.0.0.1 at 2012-04-11 23:38:29 -0700

ActionController::RoutingError (No route matches "/profilepics/small/missing.png"):

My user model has:

    has_attached_file :profilepic, :styles => { :small => "150x150>" }

What should I put for :path => & :url => ?

Form looks like :

      <% form_for @user, :html => { :multipart => true } do |f| %>

      <%= f.file_field :profilepic %>

      <% end %>

Logs look like :

Started GET "/system/profilepics/small/missing.png" for 127.0.0.1 at 2012-04-12 00:33:51 -0700

ActionController::RoutingError (No route matches "/system/profilepics/small/missing.png"):

Answer 1

See my sample:

   has_attached_file :avatar, :styles => { :thumb => "50x50#", :large => "1000x1000>", :medium => "200x200#" },
     :default_url => "/system/avatars/:style/missing.png",
     :url  => "/system/:attachment/:id/:style_:filename",
     :path => ":rails_root/public/system/:attachment/:id/:style_:filename"

• :default_url - is the path for the default image, when the user didn't upload any avatar
• "#" - this symbol is to crop image

then you can show your images as such:

<%=image_tag(@user.avatar.url(:thumb))%>
<%=image_tag(@user.avatar.url(:medium))%>

Works now!!!

For people struggling with the same issue, here's a few important things to ALWAYS make sure and check:

1. In your form, always specify { :multipart => true } otherwise, the form won't accept file attachments.

   <%= form_for @user, :html => **{ :multipart => true }** do |f| %>
   

2. In your user.rb (or whatever model you want to add attachments to ), make attr_accessible :photo (or whatever you name your attachment)

3. ALWAYS restart your server after installing a new Gem.

:) Thanks guys!!!!

There is no need to given url and path option if you simply want to display an image.

Use this line in show page and it will display image...

     <%=image_tag(@user.profilepic.url(:small))%>

And enjoy..............
