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