从视图中列出金字塔模板文件

Question

I want to make some of my templates user editable inside my web app (the actual template, not just replacing content via replacement variables). But I can't figure out how to get a list of template files.

Obviously if I know the real path I can just us regular python tools. But is there a way to get the actual file location with the some.package:templates/template.pt syntax?

I want to get a list of template files in, let's say some.package:templates/email/ . Is there a way of doing that?

To go from a dotted asset specification you may use pyramid.path.AssetResolver , as the documentation states, it looks like this:

from pyramid.path import AssetResolver

a = AssetResolver()
resolver = a.resolve('myproject:templates/foo.pt')
print(resolver.abspath())
# -> /path/to/myproject/templates/foo.pt

Specifically it has this to say about resolving paths:

If spec is an absolute filename (eg /path/to/myproject/templates/foo.pt ) or an absolute asset spec (eg myproject:templates/foo.pt ), an asset descriptor is returned without taking into account the package passed to this class' constructor.

However I would highly recommend against letting users modify the template files inside your package directly. What I would recommend instead is that you in your installation procedures have a way of copying all your templates out of your package, and then using Pyramids asset override mechanism to sub out the existing asset specs with a new location. At that point you can use the standard Python open/close file methods to have the user update the templates.
