You can explicitly name the table in the SQL database by filling in the db_table field in the metadata of a model. In a conventional declaration, the metadata stays within the nested class named "Meta" -
So one way to dynamically create multiple models, each pointing to a table, is to dynamically create those models with
type calls, changing the required data - you can store those models in a dictionary, so you can access same at runtime.
If this is done in code top level - that is, executed when the models.py file is loaded, it will almost certainly work. It may work lazy, with models being created dynamically as they are needed too - but it might not, if Django does some ORM action at the time it loads the tables.
from django.db import model
class BaseFinanceiro(models.Model):
# declare os campos normalmente
class Meta:
abstract = True
tabelas_extras = "financeiro0718 financeiro0818 financeiro0918 ...".split()
# acima, é só uma forma com menos digitação de criar uma lista
modelos = {}
for nome in tabelas_extras:
meta = type('Meta', (), {'db_table': nome})
modelos[nome] = type(nome, (BaseFinanceiro,), {'Meta': meta})
Of course I only used the "name" as a string because it was the example you gave - access can be even more straightforward if you use as a pair of "month, year" is a tuple in Python: models [9, 18] - or even a datetime.date object) - but then, of course, it depends on how you will access those templates in the rest of the code.
