pyramid_assetgen 0.2.1

AssetGenRequestMixin custom request factory mixin class that can be used to integrate Assetgen with a Pyramid application.

Configure your Pyramid app (e.g.: in your main / WSGI app factory function):

from pyramid.request import Request
class MyRequest(AssetGenRequestMixin, Request): pass
config.set_request_factory(MyRequest)
config.add_directive('add_assetgen_manifest', add_assetgen_manifest)

(Note that the AssetGenRequestMixin argument must come before Request in your request factory class definition).

Expose the directory your assetgen’d static files are in as per normal using add_static_view and then register an assetgen manifest for the directory you’ve exposed by calling add_assetgen_manifest with the same path or pyramid asset specification you passed to add_static_view, e.g., assuming you have a manifest file at 'mypkg:static/assets.json:

config.add_static_view('static', 'mypkg:static')
config.add_assetgen_manifest('mypkg:static')

If your manifest file is somewhere else, use the manifest keyword argument to specify where it is, e.g.:

config.add_assetgen_manifest('mypkg:static', manifest='/foo/bar.json')

Once configured, you can use request.static_path(path, **kw) and request.static_url(path, **kw) as normal, e.g.:

request.static_url('mypkg:static/base.js')

Under the hood, static_url will now check the path to the static file you’re serving and, if it’s in a directory that you’ve exposed with an assetgen manifest, will look in the manifest file for a key that matches the path (relative to the directory) and, if found, will expand it.

So, for example, if you have registered a manifest containing:

{'foo.js': 'foo-fdsf465ds4f567ds4ds5674567f4s7.js'}

Calling:

request.static_url('mypkg:static/foo.js')

Will return:

'/static/foo-fdsf465ds4f567ds4ds5674567f4s7.js'
