Talking about Ninja.
I am actually trying to figure out how I can distribute my crud APIs in
seperate python modules (one per model ) and make a package in my app.
Then How all the routs can be imported in the project urls.py at once.
Any suggestions?
Regards.

Also, ive recently ran into some of the limitations of drf and am
looking into moving to an api that can be less coupled with orm.
Django-ninja looks promising.

Hello.
I am seasoned SQLAlchemy user and quite good in node's sequelise ORM.
But I am new to the one with Django.So here's my situation.
I am developing an accounting (book keeping ) automation software
service.
So there are accounting rules (Debit = Dr and credit = Cr) for double
entry book keeping.
Every transaction will have 2 or more amounts, at least 1 each for
dr or
Cr.
These entries are called vouchers.
We also store retail bills, receipts and payments again all in
different
tables.
But the bills and receipt&payment tables are connected to the voucher
table.
The software generates reports such as cash flow, meaning day's
opening
balance, total Drs, total crs, and final closing balance (DRs - Crs).
then there are Profit and Loss as well as balance sheet reports.
All this needs a lot of aggregations (sum and counts ) and also
joining
of invoice + voucher and recept&payment + voucher tables.
so here are my questions.
1: given the fact that I have created materialised views in
Postgresql,
should I even care to model them and use the ORM syntax instead of
raw
query? What would perform better?
2: datasets are going to be huge some times in terms of shear rows
(all
transactions aka vouchers ) or some times sum and count will be
used in
complex queries on a huge dataset.
Again, should I rely on raw queries or will ORM plan the queries
for me
better? Should I instead create stored procedures and call them
from my
REST API?
talking of which,
3: I am using Django REST Framework and serialising records is an
option
to get json output.
Should I use it or just go with raw queries and convert output to
JSON
as required?
Again performance is a question.
Tip, My team is very proficient in SQL and yours truely can modestly
call himself an expert in the same, so maintenance is not an issue
here.
Regards.
Krishnakant.
