Nested Forms Image Preview

In documentation hasn't been specified how to preview/show images after upload. The solution is very easy.

From the form helper object, you should be able to access the model object:

<%= image_tag f.object.image_url(:thumb) %>

NB:

• :thumb is the style of the uploaded image. You can specify which style you would like to preview.
• image_url depends on how you named the attribute. In some cases it can also be image like: f.object.image(:thumb)
