Question

I’m want to display different image version:

first article: big banner

second: small banner that float to right/left

so, first thing: use cycle() but dont work:

= cycle(image_tag(banner_big), image_tag(banner_small)

or

= image_tag(cycle(banner_big_path, banner_small_path))

Only first image is displayed

There’s a proper way to make one like that ?

Answer 1

Your problem is that rails is expecting you to call cycle with the same set of strings each time. At the moment you’re passing a different pair of strings to each call to cycle, so rails resets the cycle each time. New cycles always start with their first value, hence the result you describe.

Assuming your articles had methods called small_path, big_path, something like

article.send(cycle("big_path","small_path"))

Should return alternate image paths.
