Re: [python-uk] hexagonal Django

This may be getting tenuous, but here's another example of what I think of as a "no-business-logic" app, and how we test-drove it: http://www.obeythetestinggoat.com/test-driving-a-docker-based-postgres-service-using-pytest.html Part of my blockage may come from the words "business logic" -- we d

Re: [python-uk] hexagonal Django

I think what you describe is a common situation. When I reorganised that application in a Django project, that was one aspect that bugged some of my coworkers. But I think there is potentially still some value there. The resulting one line business functions create a well-defined seam between

Re: [python-uk] hexagonal Django

You know, if you started writing a stand alone module called pythonanywhere that has no dependencies and was imported and used by Django, Tornado, and any of the other bits and pieces I think you might find a *few *things to put in there... Not that I have any knowledge of that code base, of cours

Re: [python-uk] hexagonal Django

Thanks Peter! I was speaking to Brandon at Pycon this year and he was telling me this was going to be his next talk to take on the road, and I was definitely looking forward to seeing it. Matt O'Donnell was also there, and he's done a talk on this sort of thing recently too ( https://www.youtube.

Thanks for the Brandon talk link: I hadn't seen it yet and I'm eager to see anything new from him. > Oates I did embark on the Django refactor, and in my mind it was a success of sorts. Obviously we didn't derive any immediate business value from that refactor, but it did demonstrate that the

Re: [python-uk] hexagonal Django

The Brandon Rhodes talk sounds like a nice way of looking at the problem. What I've done with my latest BIG DJANGO APP is to put the business logic into a pure Python module, Which Django imports, initialises with a storage adaptor (which makes mocking this adaptor easy) and then uses. The storage

Re: [python-uk] hexagonal Django

Thanks everyone. I've been enlightened, encouraged and forewarned by the responses to my initial question. (and thanks for the Rich Hickey talk, I hadn't seen that one) I absolutely empathise with the warnings to avoid needlessly creating extra layers or plumbing. I have a colleague who says

Re: [python-uk] hexagonal Django

I go a little way in this direction. I rarely go as far as dependency injection for business logic, but a good habit I picked up is to ensure that my business logic is put in appropriate places somewhere other than view functions, and all queries are kept with the models (ie. as Manager methods), a
