Multiple Paperclip default_urls

Question

I am using Paperclip to upload an image to my Project model and I want to have an array of default images (not depending on the style, but different images) is that posible? To pass an array instead of just one URL to the :default_url option?

Thank you,

Answer 1

No idea if this will work, but it's worth a try. Put the images 0.png, 1.png, 2.png, 3.png, 4.png on disk, and then in your model:

has_attached_file :image,
  lambda {{
    :default_url => "path/to/images/#{rand(5)}.png"
  }}

Put your other options in the lambda as well.

Answer 2

Well I didn't use the lambda function but I got the idea from Ben's answer. I just have the files (0.jgp, 1.jpg ...) and then I can just have

:default_url => "path/to/images/#{rand(5)}.jpg"

With no lambda ;-)

Thank you very much!

Answer 3

So close: If you want the images to change randomly, and not just on first load of the model:

:default_url => lambda { "path/to/images/#{rand(5)}.jpg" }
