Model __table_name__ empty

[Srikanth Bemineni]

Hi.

I am trying the new cqlengine models as part of the datastax driver. , here I am not able get the __table_name__ from the class

from cassandra.cqlengine.models import Model

class User(Model):

uid = columns.UUID(primary_key=True,default=uuid.uuid4)

fname = columns.Text(primary_key=True,required=True)

lname = columns.Text(primary_key=True,required=True)

user_id = columns.Text(primary_key=True,required=True)

email_id   = columns.Text(primary_key=True,required=True)

password = columns.Text(primary_key=True,required=True)

salt = columns.Text(required=True)

User.__table_name__ gives me None. 

Do I need to set this ?

Model.__table_name__

Optional. Sets the name of the CQL table for this model. If left blank, the table name will be the name of the model, with it’s module name as it’s prefix. Manually defined table names are not inherited.

Hello,

You don't need to set this attributes. The table name will be automatically set to "user" in your case.

Thanks,

Alan

Hi Alan,

No, it is still showing as None. The __table_name__ is not set to User

With regards

Srikanth,

Why do you need to access __table_name__? You can do User.column_family_name(include_keypspace=False)

Hi,

I can use that, but in the first place why __table_name__ seems to be not working.

I think it's working as intended. This optional attribute is used to specify the table name by defining it on the table.

http://datastax.github.io/python-driver/api/cassandra/cqlengine/models.html#cassandra.cqlengine.models.Model.__table_name__

We don't set any of those double-underscore class attributes after model definition.

The actual table name for a model is taken from that attribute or derived from the class name. Model.get_column_family_name is the way to get the actual table name.
