Structuring enormous/complex Django initiatives, and using a companies and products layer in Django initiatives : django

Hi all,

Here is a lengthy post so I’ve copied my two questions for a TL;DR. I’ve also bolded the questions within my post so that you might perhaps make a choice for any context while you happen to imagine that it can perhaps well support your solutions.

  • is there any publicly on hand (paid is k) literature or coaching on hand that covers how to simplest construction a enormous, ongoing, worn Django venture?

  • Does any individual dangle any journey writing complex Django applications with a companies and products layer as discussed in the linked vogue handbook? How has it gone for you? Has it saved more time than it’s spent having to override or reimplement Django’s supplied batteries?

I am the sole developer of a Django-basically basically based mostly web application. This application used to be developed by a dinky team (including myself) in a digital consultancy, so it’s miles rather enormous. I dangle since moved on from that role and now work with the patron elephantine-time as their sole FT developer. I contract out as need be, nonetheless, previously I dangle done the overwhelming majority of the building work.

If any of you will dangle worked for a hourly-billing consultancy, or dangle considered code written by one, you will realize the ability shortcomings. The codebase is absorbing ultimate and does thoroughly, but loads of the work used to be done ad-hoc and well-known issues indulge in assessments dangle been largely overlooked. The advance of the codebase might additionally be in need of some TLC with the hindsight of how mighty the venture has became.

Now now not now not up to within the literature I read, now not much is mentioned about how to construction these elevated initiatives. Folks talking about deliberately sterile ‘todo’ applications is largely unhelpful, as my application faces issues that are either deliberately sidestepped by malleable outlined requirements, or now not dealt with as a result of the (lack of) complexity of toy applications.

So my first question is, is there any publicly on hand (paid is k) literature or coaching on hand that covers how to simplest construction a enormous, ongoing, worn Django venture? This venture has moved some distance past a assortment of generic CRUD views and does some impressive stuff. Sadly, I receive that I’m able to now not assert to quite loads of conversations on this subreddit or someplace else when discussing venture construction.

Of all places, it used to be a subsidized post within the Django Data newsletter that I noticed the HackSoftware (never heard of them either) Django vogue handbook for endeavor applications. There might be a absorbing little bit of stuff in right here that I trust that I disagree with. Nevertheless, this yarn touches heavily on the thought that of including a companies and products layer in an application, which might perhaps encapsulate all commercial common sense / actions out of doorways of a note/invent coupling, with the intent being that most efficient the companies and products layer interacted with mannequin / ORM code.

The advantages of this are evident, it can perhaps well be much more straightforward to check commercial common sense within the (chubby) companies and products layer with out referring to your self with views, kinds, or loads of the ORM. It also enables for easy re-exercise, yada yada.

Here is now not truly groundbreaking. It be a in vogue pattern and evident while you happen to can dangle an intuition for separation of concerns. Nevertheless on the planet of Django where the usage of issues indulge in ModelForm and generic class-basically basically based mostly views appear to be quite the norm, it’s miles rather of a departure. Here is where the downsides attain in. Things indulge in generic class-basically basically based mostly views (esp. database mutating views indulge in CreateView, UpdateView.etc) muddy the waters and strictly speaking might perhaps well now not be feeble in their default states. Things indulge in ListView seem indulge in they’d be gorgeous. The magic of ModelForms — or at the least the default effect() methodology—might perhaps well now not be feeble. These seem indulge in they are mighty time-savers to me for the time being.

I purchase seeing a little bit of writing (and even it used to be a conference voice) by Django REST Framework creator(?) Tom Christie about such an structure, where he equally educated against using Django REST Framework ModelSerializers and as a replace suggests using in vogue Serializers for mutating files through your companies and products layer. This equally looks indulge in it would introduce quite loads of extra work, and the DRF documentation looks to counsel that ModelSerializers and generic CRUD ViewSets are the vogue ahead. A companies and products layer looks indulge in it can perhaps well damage this.

Does any individual dangle any journey writing complex Django applications with a companies and products layer as discussed in the linked vogue handbook? How has it gone for you? Has it saved more time than it’s spent having to override or reimplement Django’s supplied batteries?

Thanks in advance.
