I want to delete the id attribute of a model but failed, it comlains that
the model has no attribute 'id'. But I use hasattr() checked it and it does
has the attribute.
My sample code
product = Product.objects.get(pk=_id)

del product.id

I have a small background task (executed by using threading.Timer) which I
want to start up when the server starts, but doesn't need to start when a
management command runs.
The background task performs operations on the database, so relies on
importing the models etc.
I have tried using the A
Hi,
Wouldn't it be possible to use celery and tasks for this purpose?
http://www.celeryproject.org/
You could have it running all the time and have a flag in the database for
when the server is running?

Hi Simon,
You are right. Package easy_select2 calls the url method, which you can see
here:
https://github.com/asyncee/django-easy-select2/blob/master/easy_select2/widgets.py#L32
I'm going to report them that problem and I'll try also find a solution.
Cheers

I usually do
product.id = None
product.pk = None
But I'm not sure whether that's the best way to do it

Andreas,
Thanks for your answer. Certainly it looks like running celery might alleviate
the issue with threading stopping the management commands, but the problem with
your suggestion lies with that flag. If My code was able to identify that the
server is running to the point of being able to s
Oh ok,
Sorry I misunderstood your problem. How about running the celery task and
then checking if http://localhost is up?

Why do you want to delete the id field. The idea of a primary key field is
central to relational databases. If you to suppress the automatically generated
primary key then you need to assign another field as the unique primary key: as
far as I know that will prevent the id field being created.
At least I use it as part of the process to save a copy of an existing
model instance

Stating the value of either the id or pk field to None is the recommended way
to rest the primary key when you take a copy of a record, but Xudong wanted to
delete the field entirely: which I don't understand.

Hi all…
I have some models in a `test.py` file. How can I view the SQL that will be
generated for them?
Something like `django-admin sql` or similar but for models defined in
`test.py` not in `models.py`.

I have a ModelAdmin class where I am using callables to define accessors to

I.e.

readonly_fields=(field_name, other_field)
Ultimately I need to translate the labels, but
