Question

trying to make link to my recent uploaded image

<%= link_to (image_tag (post.image_url(:thumb))), post.image.url(:original), :class => 'postimage' %>

how ever it’s not working, at all…

   <% @post.image do |image| %>

   <%= link_to (image_tag (post.image_url(:thumb))), post.image.url(:original), :class        => 'postimage' %>

 <% end %>

the fun part is that

<%=  @post.image %>

works. but only shows /uploads/post/image/3/eKoh3.jpg

Answer 1

This line looks wrong to me:

<% @post.image do |image| %>

(btw your gist actually says @post.image.each do |image|, which I’m assuming is what you meant to do above)

If you are mounting an uploader on your Post model’s :image attribute, then this makes no sense. A mounted uploader allows you to upload one image, and you can’t iterate over it using each.

I’m not sure what you’re trying to do. Are you trying to iterate over all the versions? Try post.image.versions.each

Are you trying to upload multiple images? Carrierwave can’t help you with that directly. You’ll need to create a new model, Image, and mount your uploader there. Your Post will need a line like

has_many :images

And your Image model will need to belong_to :post. You’ll also need to figure out how to upload and manage images in that new table.
