  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.
