relative_path_to and non-routed representations

[Sean Davis]

I am trying to use the relative_path_to() helper function from a blog entry.  I create a summary representation that is not routed (returns nil) for inclusion in a blog index page.  I have in the blog entry:

<%= relative_path_to('/assets/plot.png') %>

However, I get this error:

RuntimeError at /blog/testing-for-non-differentially-expressed-genes/

Cannot get the relative path to /assets/Rplot001.png because the current item representation, <Nanoc::ItemRep name="summary" binary=false raw_path="" item.identifier="/blog/testing-for-non-differentially-expressed-genes/">, is not outputted (its routing rule returns nil)

It makes perfect sense to me, but is there a way to use the relative_path_to() in this situation?

Thanks,

Sean

Hi Sean,

If a routing rule returns nil, that means that the item (e.g. your plot.png) will simply not be written to disk into the output directory. If you want to link to that file, it will need to be written, which means that the routing rule needs to return something non-nil.

I think that Sean actually means that his blog entry is routed to nil,
not the image file. The blog entry wants to reference the (routed)
image with a relative path but can't.

Use a non-relative path here then relativize_paths after?

Thanks, Justin.  What you suggest will work just fine.

Yes, this was the problem I was trying to solve.
