Django API specifications and dot notation -

is there tree django dot notation can navigate , discover options dot operator of sub class?

for example can have

models.foreignkey

models.datetime

models.charfield

etc. etc.

but options? know have inheritance (i.e., check example in parent classes django.db.models ) wondering if aware of place info gathered in 1 place ( example java http://docs.oracle.com/javase/7/docs/api/ )

that's not django, that's python. dot-notation used object paths, not inheritance. did this:

from django.db import models 

this python instruction, telling interpreter locate module django.db, lookup models in , make available in current context. happens specific item submodule. possible because in python modules actual objects (some kind of singletons).

what want know what's inside module. if so, may either @ django's fields documentation or list content of module in python shell, using dir(models) (will return lots of useless stuff).

by way, equivalent:

from django.db import models foo = models.charfield(max_length=42) bar = models.integerfield()  django.db.models import charfield, integerfield foo = charfield(max_length=42) bar = integerfield()
