A library for using the wiring dependency injection library with the Pyramid web framework. pyramid_wiring injects views and provides a request scope for dependencies.
Include pyramid_wiring in your configuration:
config.include('pyramid_wiring')
Create the object graph with all your dependencies and pass it to the Configurator:
graph = Graph() ... config.set_object_graph(graph)
pyramid_wiring will validate and add all of your views to the graph during configuration and set a default view mapper that injects requested dependencies.
To make sure the WiringViewMapper is applied to all of your views, include pyramid_wiring before adding any views.
See the wiring documentation. Your views can request dependencies as usual - for example, in a view function:
from wiring import injected
@view_config(route_name='users', request_method='GET')
def users(request, dao=injected('user_dao')):
return dao.get_users()
Or a class-based view:
class UserView(object):
def __init__(self, request, dao=injected('user_dao')):
self.request = request
self.dao = dao
@view_config(route_name='users', request_method='GET')
def users(self):
return self.dao.get_users()
You can also get the graph directly from the application registry if needed:
def view(request):
graph = request.registry.graph
# do something
A new RequestScope is also included:
from pyramid_wiring import RequestScope
graph.register_scope(RequestScope, RequestScope())
graph.register_factory('database', Database, scope=RequestScope)
