Note: In the same app i have used the Carrierwave and able to display the image as wel for that model which is Category, but have problem with Product model, i am trying to using carrierwave to upload files for Product model..

Answer 1

shouldn’t it be

image_tag product.image2_url.to_s?

beacause you are using the uploader called image2!
