View Callables as a Class and Dependency Injection

Hello everyone, >From the object-oriented point of view, a Pyramid View (instance of a callable class) depends on the context and the request. Pyramid, correctly injects those dependencies into the view, during a view's class instantiation (while processing a Request). Assuming that a view depend

Re: View Callables as a Class and Dependency Injection

You can always get more stuff out of the registry in your view's init method, making it behave like an adapter for more items. The ZCA registry can accomplish most of what you would normally use a dependency injection framework for, and is there as request.registry. Check out the online ZCA book.

Having spent a lot of time with pytest over the past year, I think it could be interesting to make an IViewMapperFactory that supported dependency injection into view callables the same way that pytest fixtures are injected into test functions. While essentially be equivalent to request propert
