I have a model, Image, with paperclip attachments. The necessary routes  
are currently simply defined by

resources :images

As each image is available in different sizes (styles, really), paths  
effectively look like this

/images/1.png?size=thumb

Which isn’t pretty at all. I’d rather have

/images/1.png (for the default size)  
/images/1/thumb.png

To get this, I’ve defined my routes like this

resources :images  
get ‘images/:id(/:size)(.:format)’ =\> ‘images#show’, :as =\> :image

The second line overwrites the image\_path and image\_url helpers  
generated by the first line. Is there another solution that doesn’t  
involve overwriting and makes resources generate the size routes? One  
important constraint is that I need the :size option on #image\_path; it  
would not help to have additional routes with different names.

Hey,

have you tried match? I’m using it and still can use \_path and \_url  
without a problem.

I’m sorry if I gave the wrong impression, I can still use all the \_path  
and \_url helpers. It’s just that I’m looking for a more elegant  
solution.
