If I store the path/filename of an image in the database how do I
prevent “image_tag” helper from throwing an exception if a filename/path
has not been set?
<%= image_tag @product.image %>
or
<%= image_tag url_for_file_column(“product”, “image”) %>
Many thanks, K.
Does this work?
<%= image_tag(@product.image) if @product.image %>

Kris-
You can use this:
<%= image_tag @product.image rescue nil %>
<%= image_tag url_for_file_column(“product”, “image”) rescue nil %>

i might do something like so…
<%= image_tag product.get_image, :border => 0 %>
class Product < ActiveRecord:Base
…
returns either the image (path/name stored in db)
or default image name if image is nil (null in db)
def get_image
# default_product_image.jpg in public/images directory
(image.nil?) ? “default_product_image.jpg” : image
end
end
