Yes, first you generate your custom key, second you specify it as the id of
an object.
id = 'A1B2C3D4E5'
foo = Foo(id=id)
foo.save()
This code would create a record in the database. I also have to note that
if you read this record to an object, changed it and saved it, the record
wouldn't change

Hello Soumen, you should use a CharField with the primary_key=True
attribute for your model. This way no no automatic primary key field is
generated, your field will be implicitly unique and non-null though. Only
one primary key is allowed in a model.
class Foo(models.Model)
id = models.Cha
In the documentation they are specified, How to set Primary Key in Django
model but In my case, I want to generate custom Primary Key?!

Hi Soumen,
Are you looking for this?
https://docs.djangoproject.com/en/3.0/ref/models/fields/#primary-key
You should be able to create a field in your model and set the primary_key
to True

Hi all,
I have a custom primary key, but I can NOT get data from db.

**models.py**
class BuildRecord(models.Model):
sku_name = models.CharField(max_length=600, primary_key=True,
db_column='SKU_name')
download_link = models.CharField(max_length=1500,
Thank you for your time and response Malcom, I appreciate it very
much.

I am trying to make a pk for an object that starts with the year
followed by seven additional digits. YYXXX I want the digits to
automatically increase like normal.
I'm guessing I need to pass force_insert=True to my save if not
self.pk. I'd appreciate some advice.
TIA

4. I delete the db file and then from the command line I run:

Sorry if I'm missing something really basic here but I am a bit

Catriona,
Only AutoFields are auto-incrementing in Django. If you want to use a
custom primary key that isn't an AutoField, you will need to populate
the primary key yourself (or else create a custom trigger for it),
just as you would for any other column that is both NOT NULL and
UNIQUE.
uot;
FOR EACH ROW
WHEN (new.id IS NULL)
BEGIN
SELECT TEST_EMPLOYEE_SQ.nextval INTO :new.id FROM dual;
END;

COMMIT;
Am I missing something here?
Thanks again

Catriona,
I have very little Oracle experience, but also no reason to think that
setting a custom primary key would be different from any other
database backend.
The documentation is here:

Wouldn't it be nice (useful?) if just after inserting the pk value (in

insertion of pk values is a good alternative when dealing wit

Hi,
to avoid big drop-down lists in admin interface I'm using
"raw_id_admin=True" inside ForeignKey(), so I can enter
object IDs manually. But what happens if my related object has
a _non-numeric_ custom primary key?
In my case I've a string as a custom primary key and I&
33 matches
