Newbie question: physical file path from asset specification ?

[Laurent DAVERIO]

Hello list,

sorry for asking such a newbie question (and making you work on May Day
;-), but I can't seem to find the answer by myself... :-(


I have a Pyramid app defining a few static routes, e.g. :

> for d in ('css', 'img', 'js'):
> config.add_static_view('%s' % d, 'mypkg:static/%s' % d, cache_max_age=3600)

This allows me to use static assets in my templates, e.g.:

> <img src="${request.static_url('mypkg:static/img/%s' % img_filename}" />


Now, I would like to test in my view if "img_filename" corresponds to an
existing file.

Is there an easy way to get the physical file path from the asset
specification ? Of course, I don't want to hardcode the image directory
path in my code, and I'd also like to avoid having to add a new setting
("image_dir=...") to my development.ini.

Many thanks in advance,


Laurent.

This is the purpose of the AssetResolver.

resolver = AssetResolver()

asset = resolver.resolve('mypkg:static/img/%s' % img_filename)

asset.abspath() # -> /foo/bar/static/img/...

Perfect! Thank you very much :-)
