Is it possible in djanggo to access current request's session variables
inside _pre_save or _post_save function?
I need to save current login userid into a "last_update_userid" field
automatically by simply calling .save()
Thanks

Gdday,
After few days of intensive reading of django source codes, I don't
quite get the reasoning behind a few of key python-django design
decision that came into use in django model:
1. why use ONLY meta class in 1st place? class inheritance seems to be
much simpler, less magic, and has e

DB API documentation stated that:

Had just rewritten a basic portion of my voucher-processing accounting
model and logics to django ORM over the new year's week end.
So far, it shows up as 15% of the original lines of code, and more
readable as well (SQLs are now gone). And with the admin page
immediately available for me t

Hi Alice, try accessing via its class:

Hi, need a hand on this.
I have two applications, called accounting and enterprise, located in
myproject/accounting and myproject/enterprise. enterprise has a model
which has foreign keys in accounting. so I import it beforehand:

I agree, there seems to be a small typo in django/core/management.py
col_type = db.DATA_TYPES[data_type]
if col_type is not None:

rel_field.__dict__]
field_output.append('%sNULL' % (not f
Sure thing, Arthur.
From my observation, it's a kind of convention built into django on
every ForeignKey field. Those get a default column name with '_id'
suffix. But it's easily overridden by specifying db_column parameter. As
of Primary key, the only magic I know is if a model does not have
You meant another table that designed specifically to link those fields?
This come to mind:
class CompanyAccount(meta.Model):
company = meta.ForeignKey(enterprise.Company)
account = meta.ForeignKey(accounting.Account)
or better, a OneToOneField since a company's main account is s
No, the foreign key looks the same, but logically it's for different
purpose. You can easily imagine a table of Paint Suppliers, with a field
for their cheapest color product. And another table listing all color
products from all suppliers, with a field identifying which supplier
owns the pro

In my experience, some designers used primary key to enforce logical
parent/child relationship (where the parent's pk is prefixed into one of
the child's primay key), and usually to signify the pk fields to be
"uneditable" since it actually also doubles as "foreignkey", the value

I think you meant __dict__, instead of __dict__(). Secondly, that would
still copy the primary key, which turns into update query on save.
An easy way to duplicate in choice case would be to set id as False

Maybe it would be useful for all Django model objects to gain

There is still complication for non autofield primary key. And it's just

It used to be that if user does not define the environment variable,
django tell us with a more helpful line like

Your setting might be using DEBUG = True, which save all SQL queries and
