"""
Custom column/table names
If your database column name is different than your model attribute, use the
``db_column`` parameter. Note that you'll use the field's name, not its column
name, in API usage.
If your database table name is different than your model name, use the
``db_table`` Meta attribute. This has no effect on the API used to
query the database.
If you need to use a table name for a many-to-many relationship that differs
from the default generated name, use the ``db_table`` parameter on the
``ManyToManyField``. This has no effect on the API for querying the database.
