+17. 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.
