A quick bit of grepping shows that signals are being used internally.

I'm looking at Satchmo. Parts of it are close enough that I can adapt to how it is configured. Unfortunately, the product models and client models don't fit well, esp. the product model. I posted a similar message on the Satchmo list with greater detail but have not received any suggestions. Basically, the products I have to integrate are a set of services that can be subscribed to for short and long periods of time. Discounts are available based upon quantity of service as well as duration of service. I can certainly relate my own work with the existing models via M2M and FK but that, I believe, will be outside the scope of the Satchmo app. I am at a loss as to how to interject my required changes between the various classes. I don't want to have to 'wrap' every Satchmo class with my own - it seems a recipe for disaster 8^( After I send this message, I'll dig further into signals and the dispatcher to see if I can be a little less clueless. Thanks for giving me something to look at. Also, I just encountered last night about class templates (I think thats what they were called) in Django. I have to go back and read in detail this evening and see what I might be able to appropriately leverage.
