Django admin not working with cassandra db engine

[filipnovotny]

Hello,

with cassandra as the only db engine and django 1.9 on python 3.5, I have the following error when accessing django_admin:

NotImplementedError at /admin/login/ subclasses of BaseDatabaseOperations may require a quote_name() method

if I add that method to operations.py, I have another bug in init.py in getattr: raise AttributeError(attr) ... with attr='operators'

Isn't the cassandra engine supposed to work with django-admin?

Thank you!

I'll fix it in next version. Thanks for the report!

Any news regarding this issue ?

[r4fek]

@nirkra you shouldn't get this error on the latest version of dce.

@r4fek I'm a newbie on django programming, so I dont know if I am doing it right, but I'm receiving the same error. Regards.

Please try now. Make sure that all your cassandra models inherit from django_cassandra_engine.models.DjangoCassandraModel.

Hi,

I have tried to create a super user for Cassandra django admin. However, I am getting the same NotImplementedError. The error says "NotImplementedError : Method not available on Cassandra model fields

I am using python version 2.7.13 and django version 1.10.5

Hi, I used following example model in django admin page:

class ExampleModel(DjangoCassandraModel): example_id = columns.UUID(primary_key=True, default=uuid.uuid4) example_type = columns.Integer(index=True) created_at = columns.DateTime() description = columns.Text(required=False)

But when I try to add row into it I got following error:

return datetime.utcfromtimestamp(value) TypeError: an integer is required (got type str)

I think the front end passed a string instead of int to the mode.

Could someone help me with this? Thanks a lot!

Regards, Zhe
