DJango 1.8 test case fails with IntegrityError error

[Jose Paul]

I am trying to run DJango 1.8 test cases with DB2

Several insert statement fails 

Here is the insert command generated by test case.

INSERT INTO "AUTH_USER" ("PASSWORD", "LAST_LOGIN", "IS_SUPERUSER", "USERNAME", "FIRST_NAME", "LAST_NAME", "EMAIL", "IS_STAFF", "IS_ACTIVE", "DATE_JOINED") VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)

Value : (None, None, True, u'superuser', None, None, None, False, True, u'2015-09-17 12:31:09.562000')

ibm_db_dbi::IntegrityError: Statement Execute Failed: [IBM][CLI Driver][DB2/NT] SQL0407N  Assignment of a NULL value to a NOT NULL column "TBSPACEID=2, TABLEID=24, COLNO=1" is not allowed.  SQLSTATE=23502\r SQLCODE=-407

Except last_login none of the field are nullable .

But still DJango testcase generate insert statement  as above and pass None as value which fails .

Why this happens ?.

Why correct non null values are not generated for non null field .

Please help .Thanks ,

Jose

Hi Jose,

I looks like ibm_db_django doesn't support Django 1.6+ yet.

Hi Simon,

I am working on this support .

But the test case generates sql with null values for non null fields.

We cannot change the model ,because this is part of python ,i believe.

The problem might be the schema generated for the table from the model .
I can see only one field as non null in DB2.

Is this different from other database?.

Thanks,
Jose
